Are you at Grand Gulf?  If so I can email you a link to some notes on the network, or even a link to all of the lesson plans if you're really in the mood to punish yourself.

Send me a PM with your work email, and I'll send it over.

If worst comes to worst, I have copied some of the notes over to my laptop and can copy them over to a thumb drive for you.  They aren't really detailed on the explantion side, just basic explanations and setpoints.

I have a bunch of BWR 4 stuff. Six isn't much different and I can help you with the differences.

Thanks, getting a handle on the licensing end, now need to learn more about the plant.

"General Description of a GE Boiling Water Reactor (BWR/6)"

This is the sales tech manual. It can be purchased in paperback, and also found here: http://www.houseoffoust.com/fukushima/ge-bwr6.pdf

Operationally, it is not quite the way BWR/6s operate today, but the systems description is accurate.

Ah, I see now what these Levels are for your unit.

Here;

http://www.houseoffoust.com/fukushima/GEMANUAL.pdf

I am really shocked that you can't get this information from your training department. Or... some licensed guy that has notes on the intranet.

Just a bump for another reference posted earlier, that has some BWR4 stuff for those interested. Plus, there is a good read on corrosion, cracking and other metallurgical problems with BWRs posted earlier in the thread.

I can email you STM's if you wish. 

They aren't copyrighted or proprietary, right?

Fair use act. read it up please sir.

I once had a copyright holder's attorney explain to me that the Fair Use Act when applied to educational purposes was a courtroom defense and he offered me the chance to put it to use.

I declined the invitation.

If you're working for a Utility I wouldn't bet my job on them giving a you know what.

Im not understanding...

Allow me to translate. 

You have THREE (read that as the number "3") current or previous training instructors and currently employed utility professionals tell you to "cease and desist" regarding sending someone (outside your plant site) your company information (i.e. STM).

I hope that helps your "understanding" on "fair use".

I'm just saying ...

Whether they are RP Techs or not is immaterial. What they are are industry veterans who understand when something is issued by your utility it's meant to stay within your utility unless someone of sufficient authority gives a written release.
I'll venture a guess your utility has a procedure that says exactly that.

eh whatever man, I get bashed in my own posts, so what does it matter?


Again,


"Allow me to ask this, I've had a few requests for information on BWR stuff at the NLO level. How do I know what I can and cant share? I was under the impression all these documents are public information."

What am I allowed and not allowed to share?



The point is none of us is your Operations Manager, you should ask him.

Lol. I've been a member here for 6 years. I should be used to it by now. Guess I still get upset when I offer help and get jumped on by the entire site seniority.



Like you're the only one. ;D

Just want to ensure you are checking your site's Updated Final Safety Analysis Report (UFSAR) and Design Basis Documents (DBDs) for these questions first. If not, find a trainer to give you a 10-min tutorial on where these electronic files reside; once you know where they are, getting accustomed to doing word searches within the pdfs will be an invaluable skill.

why does LPCS have an "AOV" check valve. What does it do?

That's called a Testable check valve. It supplies just enough pressure to allow the valve to open with no D/P. It it feels reverse flow it closes even with air pressure on it. It's used to cycle the valve after maintenance.

Before I spend hours wasting my time, can I find the basis for safety limits in tech specs?

The fortune cookie answer to nearly all Tech Specs is "to avoid breaking cladding". A very few are to avoid fuel peak centerline temp., but ultimately it is all about keeping fission fragments out of the people tank. Just like your last job  :P

Yes it's either going to be in section 2.0 Safety Limits or in the Basis for TS 2.0 in the Basis Section of TS. It depends on the version.

Your RPS setpoints which are derived from the Safety limits will be in section 3.3.1.1of the Basis portion of TS. In the old version I don't quite remember where they were at but they were either in section 2.0 or in the Basis in the back of TS.

The difference is the TS they now call standard TS have a huge basis document with all kinds of great information. The older TS have a section in the back of the book that is not so robust.

Echoing Broadzilla on reading the bases. You can find it in eB or linked from you RBS Licensing home page. If you still have trouble let me know and I will show you where on Monday

Steam Flow Trip:

If one of the 4 steam lines Isolate the other 3 pass more steam. That is if other trips don't take you out.

Ok, I've tried finding a good answer, but I am failing...

Why do we only have the capacity to inject oxygen into one condensate pump line?

That is plant specific. Only your plant can answer that but most likely it's because you only needed one line so there was no sense paying money for more.

Some of us prefer risk analysis. Though sometimes I think actuaries from insurance companies are involved.


Hmmmm... PAAA... would that would mean???
