PWSCC = primary water stress corrosion cracking
IGSCC = inter-granular stress corrosion cracking
Both are in service concerns.
(You did mention QC, I've extended that to QA/QC/NDE for the answer since you were not very specific as to your intent)
I provided a link to 10CFR50.55B. from there with proper research, you should have found 10CFR50.55A in which is a reference to
NRC Regulatory Guide 1.84, Revision 34, "Design, Fabrication, and Materials Code Case Acceptability, ASME Section III" (October 2007) http://www.nrc.gov/reading-rm/doc-collections/reg-guides/power-reactors/active/01-193/01-193r2.pdfpage 6 of that document references under the Section III portion to ASME code case N-659 and N-659-1 which is for UT in Lieu of radiography. The NRC has disallowed that code case for the time being for all proposed and current new construction projects. Therein is your answer.
The best thing you can do for yourself is learn to read everything related. The NRC and the ANI/ANII will not be so kind as to provide you even a starting point in my experience. The NRC will ask you questions they already know the answer to, and you had better know how and where to get the right answer. (rightfully so in my opinion)
To elaborate, New construction is not very well covered at this time. Getting ASNT training for UT will not cut it either by itself. EPRI is the road you want to take if your going Nuclear UT. While new construction cannot base acceptance or rejection on UT in many cases, they do have to perform PSI pre-service inspections which are in effect base line UT exams. Those exams will effectively be PDI.
Before it's all said and done, I suspect that PDI will be mandated for Section III. I cannot see it happening any other way given the requirements for PSI. It's been discussed, but there has been no need for it. The recent completion project was completed early enough that the PDI program was not effectively fully implemented (late 90's)
The second post is therefore significant in that by Sept 9 the PDI program will have the force of law, and defined by the same. I would be very surprised if PSI did not follow suit shortly thereafter.
Consider this, 2007 ASME III still references 1992 ASNT SNT - TC - 1A. new construction code simply hasn't keep up with the times. Everyone thought there was no prayer for any more nukes in the states. If Obama doesn't kill them (and I can't see how he can given the state of the U.S. energy) the resurgence of nuclear power will have many flat footed.
(imagine what would happen to this country if 1/5 of it's power was cut off)
Dunno if any of this helped but there it is.
