1  Career Path / Navy Nuke / Re: Af. American Female with Bachelors degree in Physics go enlisted??? on: Jul 10, 2011, 06:31
I would recommend that you do not join as enlisted if you really want to be an engineer.  If you want to be a nuclear engineer it should take two more years of college in Engineering past your physics degree.  Then you can do whatever you choose in nuclear power. There are two major issues you will need to overcome:

 1.  If you go through the enlisted training program, they will not provide you with a Nuclear engineering degree.  This you will need to accomplish on your own, at the only instiututions in the country who can provide you with an ABET qualified degree, a civillian college or University. (this takes several years to complete, there are no real shortcuts, and no, physics is not engineering.  I am speaking the truth check the state licensing laws for engineers.) Also, there is not a whole lot of available free time in the first two years of the program for your own private study time.

2.  You will be tied to the enlisted nuclear program for 6 years, very few options and possibiliies will be available once you are in the program.  You will not be guaranteed selection for officer programs no matter what a recruiter will tell you or even your command once you in the navy.  These are very selctive programs and previous college performance plays a huge role( ie. Grade Point Average - GPA).  Your reported GPA of 2.73 is not good, meaning not very competitive.  Consider the fact that even though physics is a science and obviously more technical than say sociology,  The sociology degree with a 4.0 will get the nod because of GPA and proven success in their college endeaver.  It may not be fair but that is what happens.  If you do the math for time spent, 2 years in college is shorter than 6 years in the Navy by 4 years.  This is more important in accomplishing the goal I think.

I have some experience in this, I Spent over 7.5 years in the enlisted nuclear program.  I entered the navy with degree in Physics from the University of Minnesota, GPA 2.43.  I applied three times for OCS and was never selected.  I was sailor of the year at my command and made E-7 in just under 7 years.  There was no way to get to be a nuclear engineer in the navy for me, and that is a fact.  I completed another engineering degree while I was on active duty.  I left the Navy at 7 years 7 months and became a profesional engineer.  I have built civillian Nuclear power plants and supervised operations in them as an engineer, after I left the navy.  I am a consultant now.





2  Career Path / Navy:Getting In / Re: Nuke Deppers, Ship Dates, and Stories on: Aug 30, 2010, 10:57
     When I went to bootcamp, back in the day - late 1980's, to qualify the response here.  I was immediately grabbed (By my own volunteering with four others) and put into the Drill and choir group my first week.  After 9 days I was essentially done with the company, they forced us to take the final bootcamp physical training test and if we passed it, we were done with PT tests for the rest of Boot Camp.  We had a different schedule than the other companies, we got up earlier every day and did real simple calisthetics, breakfast and then drill/choir training for about three hours then it was off to lunch and afternoon classroom navy military training stuff.  After 4:00 PM everyday we were back in the barracks adn we did not have to do anything with thcompany like marches or anything else.  It was pretty easy and low stress compared to how the rest of our boot camp company training went.  It was pretty sweet deal back in Orlando at the time. I was there over Easter holiday, and we sat in the Pool/Gymnasium (WSPT building in Navy Terms) watching movies and ate pizza with the staff all day.  I look back on that whole 8 weeks and I hardly even remember anything bad because it flew by and I was glad to be over with that "recruit" stage. 

     We had a really fake ship mockup, the USS Bluejacket to pretend to do Battlestation drills and run around to different locations.  It was not all that realistic, no sound powered phones ar any fun navigational stuff.  Bootcamp seems long but it sure has its purpose.  The guys who served as drill instructors all tried to explain the their philosophy to me which was "We create a product for the Navy".  When each sailor leaves bootcamp, they know how to salute and the basic rank structures and the terms used in the navy.  They strive to hit that mark with every graduate.  So, whoa be fall you, the first week out of Bootcamp and you ignore saluting the Captain of "A" School.  They know everyone was taught how to do it and when at Boot camp.  No sympathy from anyone about that kind of stuff.  The montra, "never Volunteer for anything" may be true at times, but in boot camp when I volunteered for the drill team it worked out for the best I think.
3  Career Path / Navy:Getting In / Re: What do you think is the nuke school passing percentage and why? on: Aug 05, 2010, 08:18
     Something to get on thread topic.  I looked into the Graduation rate from My class in 1988 at NPS and it shows a first week light side class total of 705 students.  In my service record it shows 440 graduates 24 weeks later.  Some of those students were rolled back to other classes and a few went on to officer programs, but most were academic or personnel reliability program (PRP)failures.  I saw a similar rate in 1989 as a SPU reviewing student records as they came into prototype.  Then in 1990 things really started to change, we really started feeling the pump versus filter phenomenon as prototypes were getting less available due to age (S1G Decomm, S8G Waterbrake Broken, S1C decom plans, D1G COH for over a Year, MARF in a 2+ Year refuel, and the first two float-o-types were not ready yet in Charleston).  As I trained students through part of 1991 I noticed that less and less were failing out at Power school.  Other friends of mine who went back to prototype after I rotated to the fleet were giving me the same information. 
     
     There is no doubt that attrition and performance in NFAS and NPS were treated a lot differently in the past.  Just looking through my boot camp slass photo, 21 nukes and only 5 made it to the fleet.  The program was not made for people with tout the drive to be able to finish what you started.  The program was not about "helping" students make it through.  The "help" was provided but performance standards and academics were not sacrificed for any one student.  You had to put the hard effort in and meeet the requirements on every test and class in the program or you were facing an academic board. 

     I saw once in 2 years at prototype that a civillian over ruled an "AC" Board recommendatino and allowed a student to pass.  As expected it turned out Bad.  We heard from the fleet about three months later that the guy was denuked for blazing logs on shaft alley watch on the Big E.  The crew on the ship was mad at us, the staff at prototype, and we felt bad but had absolutely no power to do anything about it once the COC made the decision.  The standards worked then, and in my opinion, they performed an important function for the type of job we were being sent to do on a ship.  Once you left power school that formal classroom experience was essentially over and you did not have time to revisit that again especially on the ship, so you had to stand alone in knowledge from NPS to get qualified and do the ultimate job you were trained for at the controls and valves in the plant, without being a risk.

     The fact that less students fail today may be good.  I am sure it saves the navy money in costs for training and recruitment.  But it also has changed the fleet a little too I am sure, speaking as a former MM.  It seemed like every command I saw back in the day there were at least two people in A-Div that had failed out of the NUke Program.  On the nuclear ships this made them really valuable to the crew and they had a lot more formal trianing than the new fireman coming in from A-school, in a lot of cases and this was a huge boost to the conventional side of the rating.  So I do not know what impact that has had on all the rating mergers and training of crewmwmbers when ther are less Nuke school failures to move ouot to the conventional side of the fleet as ready made PO3's.

  Just my view on the topic, mileage may vary , I could be wrong etc.
4  Career Path / Navy:Getting Out / Re: Is anyone here considering something non-nuclear related after leaving the navy? on: Jul 16, 2010, 04:27
    I work as a design Engineer after obtaining My P.E. License after I left the Navy.  With a P.E. your starting salary without bonuses should be 85K.  With bonuses and specialty pay such as at a construction site where you would receive per diem and other allotments it rises to about 120K.  That would be at the 2-5 year Point after leaving the navy.  All of my work is Non-Nuclear now.  It still has requirements and building codes to follow but the pace is still more interesting than doing the same work forever for a utility that will not allow you to have a pension (I left Nuclear Power when they froze mine at Excel in 2001).  You can basically work in all 50 states if you work for alarge enough company that has contracts across the U.S.  I have worked in most of the states since 2002.
    As a manager in 1997 I was making 85K in a Paper mill managing the steam plant.  When I left that job to go back to Nuclear power I was earning 93K.  After I worked in Nuclear Power in 2001 to 2002 I realized I was not happy with the job I had and I have found other work that is intersting and in need of my services.  Private industry has alot to offer people who want to take on challenges and work hard, so do not just think Nuclear Power is the only avenue after the navy to obtain good employment.
5  Career Path / Navy:Getting Out / Re: Joining Navy Reserves after 6 years active duty on: Apr 15, 2010, 02:21
When I left the Navy in the mid 90's, they were forcing nukes to take 1 paygrade down to direct cross to your conventional rate in the reserves because they were so overmanned.  That combined with the non-nuclear work turned me away.  The only unit left in Minnesota after 2005 is an aviation unit in Minneapolis.  Too far for me to travel and a lot of extra cost to be involved.
6  Career Path / Navy:Getting In / Re: SWO(N) Getting In. NUPOC Route. Did VIP Tour. Officer App questions. on: Mar 23, 2010, 12:07
The economic situation has made this era very much like the late 1980's and early 1990's for selection and retention criteria.  The Navy had their pick of the very best applicants and could afford to turn away a lot of otherwise qualified applicants.  it was very competitive then , not that it is not competitive now, but that tweak in the economy made a lot of people look at the NUPOC program in the late 1980's, and there was alot of applicants trying to get approved, just like now apparently.  Also, there appears to be alot less billets right now, in 1989 there were over 100 sub billets available in the June 1989 timeframe.  There was about the same surface billets (More Cruisers than carriers then).  All in all it was hard to get accepted for a number of years in SWO(N) (I am referring to OCS, that was my experience).  In the mid 1990's when the Seaman to Admiral Programs and STA 21 was formed, It changed the way the enlisted groups were slotted when accepted into the different Nuclear communities and the total number of available slots outside the navy.  That period lasted about five or six years after the stock market crash of 1987.  I watched it happen and followed it through the mid 1990's.  So it may be safe to predict this will be ocurring agin unless a significant number of new ships and subs are commissioned to create more billets.  The economy tends to be the navy recrruiters best friend and a college graduates biggest problem.  Good luck on getting accepted either program is great SWO(N) or subs.
7  Career Path / Navy Nuke / Re: Pros and Cons of enlisting as a Nuke! on: Nov 19, 2009, 04:05
     You will get really great opportunities to learn Nuclear Propulsion equipment.  But, it will be the navy way and in the U.S. military organization.  You will clean toilets, wash dishes, scrub barracks floors and will generally be made into a work slave for several years before you have qualified as a nuclear trained operator.  Then, you will still clean decks, do laundry and work on equipment as the navy sees fit.  This is the simple basic explanation.  You will probably have days wondering why did I volunteer for this? 

     If you take advantage of the important access to the Nuclear training and ignore the mundane cleaning tasks as just necessary housekeeping, then your attitude will be correct.  If you decide you are much more valuable than someone who does laundry, then you already have the wrong attitude and you will be very unhappy for your whole six year tour.  Nukes work longer hours everyday and they are expected to perform at a higher standard in their jobs, this is the heritage of the program.  So, when you see the coners or topsiders leave early each day and you are still in quals and mess cranking, you will need to understand, this is what you have volunteered to do. You will get a little more money than other Navy rates but not a lot, unless you re-enlist.  That option will not be available to you for at least two years into the program.  Military life is hard, boring sometimes and in the end usually rewarding if you take advantage of the training to the fullest degree.  But, everyone here who has been through it, probably had a very similar experience and in the end it was what the individual person made out of the job.  For some, it is a great career, others a great experience, and for some who never wanted to adapt to the navy and the nuclear program, they were bitter and unhappy and still to this day many years later despise the job for their own reasons.  It will all be up to you, to meet the challenges in front of you. 

Good Luck and thanks for choosing to serve our country.

9  Career Path / Navy:Staying In / Re: any Degree? on: Apr 16, 2009, 05:04

So where do you get your experience from?  I had no problems transferring my degree (TESC) into a masters program with an ABET school (yes their program was ABET too)  JsonD13 .


Here is where my experience comes from and many others I have discussed this with have had similar experiences.

1. Univ. of ND School of Engineering and Mines, 2. Univ. of Minnesota Institute of Technology, 3. University of New York...  None would accept a Navy Smart transcript, and they would not accept the credits on the University of New York Regents college degree I held from 1990, not even the Excelsior Degree program which was ABET accredited in 1998 would accept all of the Navy courses into their ABET Technology degree program, and that is now the Univ. of New York Regents College, it was rolled into Excelsior and my transcripts now say Excelsior on the cover letter they send.

     Specifically I am talking about the navy credits in Reactor Systems, Technology, Chemistry, Atomic Physics, radiology.  None of these would transfer directly because of the ABET credit course description requirements at each of the Universities.  ( If you carefully read the recommendation for credit information it discusses the U, L ,V etc on the smart transcript information and it dismisses any responsibility to allow acceptance any where it is entirely up to the program which you are applying. They require certain numbers of hours and levels of accreditation that do not exist in the Navy even though certain colleges do give credit for the courses.  I fought with them for six months to get the University of ND to accept 3 classes from the Nuke school training, and that was all I could get them to accept.  Other Universities were even less receptive.  Although, if I wanted a degree in Social science they would most likely transfer most of the credits that they could find an application for in their program requirements. 
10  Reference, Questions and Help / Nuke Q&A / Re: Pressure Increase = How much heat?? on: Feb 23, 2009, 09:12
The Answer to the Second Question, B) requires some different assumptions about the transient change in the pressurizer to create a plan to solve it.

What is the amount of water removed from the Pressurizer to drop pressure 100 PSI?

Assumptions:

No spray actuation occurrs during the event.
Heaters are constant and no change in energy level.
No overall temperature change occurs during the time of event.
All fluid that leaves is liquid through the submerged outlet.
Ignore height diferences as small.

Initial Conditions:  Po = 2100 PSIA,  Vo = 1200 Cubic Feet

Final Conditions:   Pf = 2000 PSIA, Vf = Unknown

The relationship of the pressure of the Steam volume for a steady state system with these assumptions can be viewed as:

 PV = nRT.  An Ideal Gas relationship. Where P = Pressure, V = Volume, n = molculer ratio, R = Gas Constant

For temperatures between 65 F and 1400 F values of R and Specific Heat remain relatively stable for Water. ( ref Engineering Thermodynamics 6th Ed - Shapiro Table A-21E).

The only work or energy change of the steam is due to volumetric change.  Thus, the two states can be set equal to each other. The n and R terms are considered equal and cancel.

Po X Vo = Pf X Vf    Re-arrange this to solve for the final Volume (Vf),

Vf = Po X Vo/Pf   =  2100 PSIA X 1200 Cu Ft/2000 PSIA = 1260 Cu Ft

The difference in Volume id Vf - Vo = 1260 Cu Ft - 1200 Cu Ft = 60 Cu FT    Solution ( This is Equivelant to approximately 448 Gallons of Water.


A similar approach can be used to solve the third Question C.)

If 10 Cubic Feet of Water are added to the Pressurizer, what will be the pressure increase?

By using mostly the same assumptions as above, the P-V relationship can again be used.

No spray actuation occurrs during the event.
Heaters are constant and no change in energy level.
No overall temperature change occurs during the time of event.
All fluid that enters is liquid through the submerged surge line.
Ignore height diferences as small.

In this case though the difference in Volume is given as 10 Cu Ft Which Makes Vf = 1190 Cu FT, so the unknown value is Pf.

so set:

 Pf = Po X Vo/Vf   =  2100 PSIA X 1200 Cu Ft/ 1190 Cu FT  = 2117.6 PSIA 

Take the difference between the Vf and Vo = 2117.6 PSIA -2100 PSIA = 17.6 PSIA  Solution.

This is the simplified method of steam volume problems, there are a host of other issues that can be considered when you allow temperature and heat addition to vary during the process transient, but the results are similar in scale.
11  Reference, Questions and Help / Nuke Q&A / Re: Pressure Increase = How much heat?? on: Feb 23, 2009, 07:07
To answer this question the actual conditions in the pressurizer at the starting and ending conditions need to be stated or assumed to determine the method of reaching the final conditions.  Looking at the data you have provided, a simple set of conditions can be assumed to simplify the method of solution.  As an exercise example this is the method of solution, any actual numbers can be inserted to abtain the results.

Looking at each question as its own separate problem, take a.) first:

What is the heat needed to make a 100 PSI increase in pressure?

Assumptions:
No Spray activations occur during the pressurization.
Only heaters provide heat into the pressureizer Volume.
No overall change in Steam volume occurs.
No changes in ambient heat losses during the pressurization.
Steady rate of heat input from the heaters during the pressurization.
Initial conditions of pressurizer are that the steam and water are saturated.
Final Steam conditions are slightly superheated when heaters de-energize.
Pressurizer is indeed a cylinder without hemispherical heads.

Initial conditions        To = 642 F, Po = 2100 PSIA, Steam specific Volume Vo = .17501 Cubic Feet/LBM
                                       Water specific Volume Vo = .02615 Cubic Feet/LBM ( Ref. Saturated Steam Tables)
                                       Enthalpy: H steam = 1130.5 BTU/LBM, H Water = 683.8

Final Conditions         Tf = 665 F, Pf = 2200 PSIA, Steam Volume Vo = Vf (Reference Superheated Steam Tables)
                                       Enthalpy: H steam = 1152.1 BTU/LBM, H Water = 695.5

Pressurizer Steam Volume = 1200 Cubic FT, Total Volume = 3,205 Cubic FT, Water Volume = 2005.3 Cubic feet 
(This was computed using an inside diameter of 9'-11" given above - 6" Wall thickness X 41.5' Wall height Cylinder no hemispherical heads)

Steam Volume Calculations
Find LBM Steam to be heated:    1200 Cubic Feet X 1LBM/.17501Cubic feet = 6,856.8 LBM Steam
Find Steam Enthalpy Difference: H Steam Final  - Hsteam initial = 1152.1-1130.5 = 21.6 BTU/LBM
Find Steam Heat required:       6,856.8 LBM X 21.6 BTU/LBM = 148,105.8 BTU
Convert to KW:                   148,105.8/ 3413 Btu/KW-hour = 43.39 KW-Hour


Water Volume Calculations
Find LBM Water to be heated:    2005.3 Cubic Feet X 1LBM/.02615Cubic feet = 76,684.5 LBM Water
Find Steam Enthalpy Difference: H water Final  - H water initial = 695.5-683.8 = 11.7 BTU/LBM
Find Steam Heat required:       76,684.5 LBM X 11.7 BTU/LBM = 897,074.6 BTU
Convert to KW:                   897,074.6/ 3413 Btu/KW-hour = 262.8 KW-Hour


Add Steam and Water heat numbers together for total volume heating incurred:
262.8 KW + 43.39 KW = 306.2 KW    Solution. 

There are a number of significant transients that can occur that is why it is more difficult to solve when you include the movement of fluid and volumes as well as varying heat rates into the transient of pressure increase.  But as presented this is a simplistic method to determine full volume ehaeting while ignoring some of the other more detailed issues.  Hope this helps.  If I get time I will answer B and C Later.

     You have made an assumption about the information provided for the student.  Only data was given and stated as "realistic".  I wanted the student to get their own information on paper and get an answer.  The student never actually did provide all of the data they were using specifically the KW of their system from their table in the textbook they had.  Without their specific numbers I could not and would not do their homerwork problem for them. I was not going to do their calculations and let them run to their classroom with the homework done.  As it turns out the student never even posted their answer when Beercourt had asked them to let us know how it turned out for their exercise.  "Give a person a fish and they eat for a day, teach them to fish and they will feed themselves".  The first rule of getting someone to do their own work is teach them to "Fish" aka solve, and then they can solve for themselves. 


13  Reference, Questions and Help / Nuke Q&A / Re: Pressure Drop??? on: Feb 18, 2009, 11:21
Okay, lets use real numbers from a real Westinghouse US four loop Plant.

WBN-1, May 96
Power 1246 MWe
Flow   144,000,000 LBM/Hour = 288,461.5 GPM/ 4 Loops = 72,115 GPM/Loop
Motor KW = 5850
Pump Eff  = .73
Motor Eff  = .91
.7457 = conversion KW to HP
3960 = conversion of FT- LB/Sec through HP and seconds to Minutes
Pump curve point is determined from initial design curve (with original S/G's and pump seals installed)

Pump Head = 3,960* (.73) * (.91) * 5850 KW      (Reference Camerons hydraulics Chapter 1-18th Edition)
                          72,115 GPM * (.95) * (.7457)

                = 15,389,173.8       
                     51,087.6

                = 301.23 Feet (Water column)        Note 2.26 Feet of Water Column = 1 PSI

    Thus     301.23 Feet/2.26 Feet/PSI  =  133.2 PSI Differential head across the pump (Calculated Point)

Reference (Displayed as 125 on westinghouse P2500 computer).

This exercise that the student was asking about is not an NRC test about the FSAR, it is about how do you get the numbers that are in the design background for the plant and what do they mean.  Any one can do this same one point steady state approach at their plant using their known equipment ratings, flows and KW of the system. 

This is how it works, the why, behind the numbers that are read in the control room and in the technical manuals.  Granted this takes some basic liberties by ignoring transient analysis, but for a 1 point assessment of an steady state operating condition these are the basics of how you approach the solution.  That was what was asked initially and answered to stay on topic.  (By the way I have the numbers from this time frame because I downloaded them from the P2500 and verified them on the Eagle 21 system during full unit surveillances during initial startup and full power testing).
14  Reference, Questions and Help / Nuke Q&A / Re: Pressure Drop??? on: Feb 18, 2009, 04:42
Just like I said in my post you can put any numbers you want in the equations based on how a plant system runs specifically loop flow, HP or KW of the motor and you will get the differntial pressure number that defines the loop.  There are Many commercial 4 loop reactors and not all are the same especially around the world.  So, put in the specific plant data. I would expect to get about 70 different sets of data from the plants in the US based on different loop configurations, flow rates and pump designs.  Remember your plant is not the one the original poster is asking about, the person was asking about the one in the "Classroom textbook table exercise" Which has specific variables.  So, relax and feel good about knowing your plant parameters. 
15  Reference, Questions and Help / Nuke Q&A / Re: Pressure Drop??? on: Feb 16, 2009, 02:38
I am updating the last post to use the flow that you provided of 95,650 GPM which is divided then by 4 to get the individual loop flow.  Without you providing the KW for the loop Pump, I still used the 650 KW based on my own experience.


Pump Head = 3,960* (.83) * (.94) * 650 KW
                  23,912.5 GPM * (.95) * (.7457)

                = 2,008,234.8        
                     16,940

                = 118.5 Feet (Water column)        Note 2.26 Feet of Water Column = 1 PSI

    Thus     118.5 Feet/2.26 Feet/PSI  =  52.46 PSI Differential head across the pump 

This would be the number that reflects the conditions given by the system parameters, if the pump KW was 700 or 600 KW very little would change the range would still be in the 50 to 60 PSI differential at this flow rate condition all of the rest of the physical attributes are based on the Physics of water.

16  Reference, Questions and Help / Nuke Q&A / Re: Pressure Drop??? on: Feb 16, 2009, 02:21
you need to divide total flow by 4.  then you need the KW of the individual pump involved in one loop.  In a Westinghouse plant  4 loop 1200 MW Electric gross power output,  this should be about 650 - 700 KW.  When you multiply all of this out, you should have:

Pump Head = 3,960* (.83) * (.94) * 650 KW
                          13,678 GPM * (.95) * (.7457)

                = 2,008,234.8       
                          9,690.3

                = 207.24 Feet (Water column)        Note 2.26 Feet of Water Column = 1 PSI

    Thus     207.24 Feet/2.26 Feet/PSI  =  91.69 PSI Differential head across the pump


    Each plant has a different KW number for the pump based on normal load conditions, temperature and pressure.  But this is very realistic for the 4 loop Westinghouse design.  I have worked on the 1275 MW 4 loop plants and pump KW loads were as high as 800 KW depending on coolant temp and core fuel status of life.

If you are given the KW of the running pump in the loop at the steady state conditions you can back calculate the total pressure drop (Pump Head), based on the Pump and motor performance curves.  You can assume some industry standards for Motor efficiency = .94, and Pump efficiency = .83.  You need to have the correct Specific Gravity of the fluid pumped typically .95 for the hot water loop.  Also you need to know the Flow in the loop in Gallons per minute ( You can convert to this from a LBM/Sec number if that is given).

Then use the Equation:     Pump Brake Horsepower =  Flow(GPM) * Pump Head (In Feet) * Specific Gravity
                                                                                           3960 * Pump Efficiency

     From This you can then use the relationship that:   KW (pump) = Pump Brake Horsepower *.7457
                                                                                                      Motor Efficiency

By relating these two equations you solve for the one unknown which is:     pump head (In Feet).

You do not need to know all of the other specifics of the loop to obtain this overall number.  It includes pipe frictional losses as well as all of the other height variables and component through put losses. It does not quantify what each component headloss is only the over all total for the loop.  These numbers should be available from the system you have as basic operating parameters not related to the S/g's or the reactor fuel channels etc.  This is basic fluid flow centrifugal pump laws. 

If you don not have the pump information given such as flow or KW then you have no way to solve anything and why would you want if you do not have even basic operating data to work with.  It gives you no hard background to make system assessments.

How do they do the Lab online? 

Almost all Universities require a lab as part of their curriculum for Physics and Chemistry classes that are calculaus based.  It is strictly required in ABET programs also.  Just wondering if you knew how they get the lab work done.

When Port Nuc Instrumentation burns up the power supply at 0130, powers down, a scram occurs and there is no indication of pressurizer level, you need both if you want to get out of it with an intact set of fuel rods.  Real casualty and real recovery experience on D2G plant.  Absolutely used both, the theory and years of operating experience to maintain plant parameters while repairing the equipment.

My tour was at S3G in the late 80's and into the early 90's.  For about one year we were the only protoype training in New York and the floatotypes were not built yet.  It was crazy the number of students we pushed through in that last year of operation.  I really liked living in upstate New York and I really liked the people that I worked with at the facility.  There were a lot of long hours and that 15 day marathon of dayshift to afternoons was a killer.  Time went fast though, and it helped me become a better operator and instructor later in the fleet.  I would agree that it was hard to drop students then, and is probably even more difficult now (pump vs filter issue).  To be fair though, we really only needed to drop an average of about 4 students per class back then.  We had to nurse quite a few along, but that was par for the course in prototype training. That was when  a class was 100 students ( ET,EM, MM) spread out across 4 sections. We would have up to three full classes in hull at a time to schedule watches and checkouts.  Staff EWS quals were a problem then, they were hard to get people through the watches and suck up the extra load in each section during that time.  We usually had 6 SPU's and 2 staff Sea returnees in each MM section to make the plant run, not a whole lot of slack to get through all of the other duties. 

All in all I had a good tour , never went to the green table and trained a lot of good students.  But, I did not go back to Prototype at the end of my Sea tour, I made the choice to get out because I had the feeling of "Been there, done that" and wanted to try something new.  From my original section at prototype of the 8 MM's that were there, I know two of them did go back to New York to be instructors again.  That is not a bad return of number of people who knew what to expect. 

The most important thing for staff on a second prototype tour is to have the chance to do something other than on crew watch and instructor.  They need a chance to work in classroom phase or off hull support roles to break up that intense training pace.  That is my two cents worth on Prototype duty.

There is only one university in the Country that will let you take approved ABET Classes online, while enrolled in a Engineering Degree Program, at any time of the day leading to the full degree in Engineering.  That is The University of North Dakota.  You can be located any where in the country.  You still need to take the class in the semester schedule but they are flexible on test dates and online homework assignments.  They will give you about 18 undergraduate credits like you would see listed on the ACE Smart transcript for lower level Engineering and base coursework, no vocational courses.  Then you can take most of the Llib ED courses for about $200 per credit.  The Engineering courses are another matter, they cost about $480 per credit.  But, you can sure get the traditional graded ABET Engineeriong Course work done online.  They have admission requirements and GPA requirements to continue to be enrolled.  It is a challenge, even for nukes, but it sure met my schedule while I was working a full time job. 

Gettting another type of degree from a liberal arts college is a whole different matter.  They will give you many more credits from your Navy Smart Transcript.  So, it is a matter of understanding where you want to take your education to your next position in life.  I know a lot of people who received degrees from Excelsior College online and Thomas Edison State University and it was relatively easy to get credits from NNPS, NFAS and NPTU allowed.  Then, only a few courses were required to get a Bachelors degree in science or technology. 

I know from my experience though, that all of those Navy ungraded credits on your transcript will cause red flags when trying to transfer them into an ABET college Engineering program and it takes some time to try to get them accepted.  I completely recommend completing education over the time one spends in the service and using tuition assistance and the GI bill if available.  The cost of college is enormous today and it is difficult to try and pay fo any type of a higher education.  Hopefully as time goes on there will be more Online opportunities for College degrees that are more receptive to the Navy Nuclear training Credit Evaluation.

23  Career Path / Navy Nuke / Re: Norfolk Naval Station on: Nov 29, 2008, 02:16
I spent 4 years in Norfolk and they were all the same as far as work hours and traffic.  I lived in Greenbriar ( Part of Chesapeake) just off the I-64 loop that puts you exactly half way between Portsmouth (Norfolk Naval Shipyard) and Norfolk (NOB Naval Base).  I would get up at 4:30 AM every day and drive in to the base to get there before the rush.  After parking in the lot I could be on the ship at pier 10 by 5:10 AM.  I could grab another hour of sleep and then get dresed and go to morning briefings and quarters.  Any other attempt to get to the ship in the morning after say 6:00 AM resulted in traffic gridlock and no parking left near the piers.  This was mostly true for Portsmouth Shipyard times and the Newport News Shipyard.  I was stationed in San Diego and it was not even close to that bad in the morning on I-15 or I-5.  You will get used to the traffic and the congestion though.  It is when you leave there that you realize how really bad it was from a traffic standpoint.  Additionally, when I was there in the early nineties, it was the highest murder area in the state.  There were more police officers killed in the line of duty in the Hampton Roads area in 1993 than any other metropolitan area in the country.  I believe it has become better over the years, but there were some extremely dangerous areas at night in the Hampton Roads Metro region. 

When People who actually lived there for an entire sea tour tell you how they had to go about there routine, they are not kidding about what had to be done to get through each day.  Then, there is always the unkown days where a battle group pulls in and overwhelms the base for a while until you deploy.  This can even mess up your normal routing becasue things get even worse in the short term for access and parking.  I would not want to go through all of that again just so I could go home each non-duty day.

When I was staff at prototype at New York in the early 90's I had the pleasure of meeting three Prospectove XO's and standing watch with them.  They were all very bright and very laid back, they had all commanded aviation squadrons prior to the nuke training.  They actually came through all of the training exercises pretty well and I had a lot of respect for them.  One thing that scared me was the fact that once they went through engineering drills as a watchstander they all agreed that this was great fun and they wanted to do them a lot on their ship because everyone seemed to be so enthusiastic.  Apparently we may have created some monstor's from a casualty drill practice standpoint but they sure did mean well because they saw value in us and our training. 

I saw all three of them go on to command the carriers, GW, Truman and Roosevelt following XO tours on other carriers.  One even commanded the Mount Whitney for a year.   The quality of the training program at that time was really high and although they had a senior rank, there were no corners cut, even including cleaning the LO purifier.  Even though we gave them the option of observing some one else do the practical factor.

I always thought that the selection process for those aviators must have been tough to get to that point, because they were all very talented and very intelligent.  ii hope they are still applying all of the same criteria now because as I look back on it what was being done as far as selection and training really served the navy well during the 90's.

I copied the Texas Professional Engineers Licensing Board of Information below from their website:

http://www.tbpe.state.tx.us/

You may be able to become licensed provided you meet the experieince requirements which can be found at their website also.  A licensed Engineer has to provide signed documnentation of your experience in responsible charge of different levels of work for a specified period of time following your graduation.  Go the website and go through the application requirements and the review the reapplication itself and determine if there is anything else you need to do.  Contact them when you are ready to apply prior to sending in any information because sometimes requirements change and you may need to get more data or information. 

I wish you good luck in your future.


"Basic Requirements for Licensure
There are three basic categories of requirements that must be met for licensure: Education, Examinations and Experience.

Education
You must have earned one of the following degrees or degree combinations:

1) An accredited degree, as described in subparagraphs A & B of this paragraph:
A) Bachelor of Science degree in engineering from an EAC/ABET accredited program in the United States or Board designated equivalents from Canada or Mexico, the Washington Accord, or the list of substantially equivalent as documented by ABET.
B) A Board-approved combination of a Bachelor's degree in one of the mathematical, physical, or engineering sciences and a graduate degree in engineering from a university with an EAC/ABET accredited undergraduate program in the same discipline of engineering.

2) A non-accredited degree as described in subparagraphs A & B of this paragraph:
A) Bachelor's degree in engineering technology from a TAC/ABET accredited program.
B) A Bachelor's or graduate degree in mathematical, physical, or engineering science approved by the Texas Board of Professional Engineers.

All degrees or combination of degrees must have at least:

8 hours of math beyond trigonometry (courses such as calculus and differential equations), and
20 hours of engineering sciences (courses such as mechanics, thermodynamics, electrical & electronic circuits, materials science, transport phenomena, computer engineering, etc.)

All foreign degrees from countries other than those listed in 1A above must have a Foreign Credential Evaluation and must be translated into English."

"Examinations
All applicants for licensure must take and pass the Texas Ethics of Engineering examination. The Texas Ethics of Engineering Exam is an open book examination concerning the Texas Engineering Practice Act and the Board Rules, which should be completed and submitted with a license application. Applicants must also take and pass or qualify for waivers of two examinations - the National Council of Examiners for Engineering & Surveying (NCEES) Fundamentals of Engineering (FE) examination and the NCEES Principles and Practice of Engineering (PE) examination. The FE and PE examinations are both 8-hour tests and are given twice a year at several locations in Texas (certain PE tests are given only once per year). The testing dates are scheduled for April and October. Texas residents and non-residents who are otherwise eligible for licensure may register to take the FE examination without submitting an application to the board. Applicants with appropriate experience must apply and get approval to take the PE exam."
