Experience
An applicant must have a minimum of five years experience. Training may be substituted for experience if the applicant will submit to the Board information about the program and proof of completion. This information should include curriculum, typical examinations, and passing requirements for radiation related subjects.
Experience credit allowed for formal education, company training programs and applicable military training is cummulative up to a maximum of two years. Note that an applicant may not claim work experience while in formal classroom study.
Kinda hard to meet the 5 year experience requirement and still be a junior....... 
Got it! Here's a bit of an explanation for my rookie mistake. I'm a 20-year Navy ELT (submarines) with two tender RadCon/RCSS tours, Plant Leading ELT at Prototype (635 in Charleston back in '99), two SSN LELT tours, three years as the Squadron Chem/RadCon guy, blah, blah, blah. Anyway...

http://www.nukeworker.com/forum/index.php/topic,4395.msg28914.html#msg28914, it looks like I could wiggle my tender RadCon, ELT, and time in the shipyards towards some serious SHP progression. The money is obviously enticing, but I think it's probably not smart to skip straight to SHP for my first-ever outage. I'm really good at Navy RadCon, but that + $3 will get me a cup of coffee when I'm driving around town outside the confines of the Navy base.
So I was thinkin' - which loosely translates into, "
here is where I could probably use some fixin'":
I bone up for two months on the NRRPT, and take it in Feb 08. (I'm kinda blessed in that I usually take written tests pretty well. During oral exams, let's just say I won't be doing any Right Guard commercials...) At this point I'd have to pay the exam's late-application fee, but
c'est la vie. Of course, this whole NRRPT exam for me is based on allowing my Navy "life experiences" to count toward the exam's prereqs - and I haven't seen anything yet which clearly tells me that that's OK, so this whole exam thing for me could be completely moot. However, let's just say at this point that hypothetically I do take the NRRPT in Feb 08 (however hypothetical that may be).
Even if I do pass the NRRPT, and even if I do happen to squeeze into all the SHP prereqs, I'm thinking that I oughtta tackle my first-ever outage going in as Jr HP. Maybe I'm crazy, or maybe I'm just plain dumb for thinking such thoughts, but here's how I look at the two entry-level options:
Jr HP. Compared to SHP I lose roughly $4K over the course of an outage (which ain't chump change), but I'm still payin' the bills and keepin' food on the table. If I trip up a time or two on the civilian-side learning curve, I receive a few choice epithets & a roll of the eyes, I make a mental note regarding the f--- up, and I carry on smartly. On the other hand, if I do reasonably well then maybe I get a couple people notice my name & face and say to themselves "he's OK" (which is important because paths seem to cross frequently).
SHP. I put maybe 40 extra C-notes in the bank from the outage. If I dork up a few things (or more than a few things) and do a sub-par SHP job right out of the starting blocks in front of God & country, then I'm toast; I'll be stuck deep in image rebuild/recovery mode for a pretty good stretch of time, which is not a fabulous way to be starting out one's career...
So with the Jr HP option, I loose a chunk of $$$ but should be able to manage to not lose face (and might even gain some good PR). With SHP I bank some extra bills, but may have to lay low ("You want fries with that?") for a spell after that first initial job is done.
So unless a major epiphany strikes me and changes my mind, I'm going Jr HP for my first job. And besides, it's my emphatic feeling that I oughtta have at least
one "SHP U/I" before I actually take that job on fer chrissakes. In fact, I'd like to do a Decon job even before going Jr HP, but I'm kinda worried that I could/would be "locked in" as a Decon guy after that. I could imagine that after finishing Job #1 as a Deconner, any company getting my résumé for Job #2 would raise their eyebrows and say "You did Decon at your last job? We need experienced Deconners for our outage." (And thus commences an uphill battle...) Maybe I'm wrong?
Anyway, coming full circle now and getting back to the NRRPT:
Even if I could/can satisfy all the prereqs for SHP, I plan on taking a Jr HP job (or two or three Jr jobs, depending on how hard it is for me to unlearn Navy RadCon). So I was just wondering if I'd qualify for a NRRPT bonus as a Jr HP during the first job/jobs (or if I would have to wait until I actually took on the role of SHP). Regardless of whether I get credit or not as a Jr, I'm still planning on taking the NRRPT this time around; even if it turns out that it isn't a pay-raiser for Jr HP, it can still be a door-opener.
Sorry this post is so long – hopefully it wasn't too painful to read...
