DPV -Reply While doing a bit more research regarding weld flaws, I discovered there is a 1998 ASME, Section lil, Division 3, Code for containment systems and transport casks for spent fuel (I have borrowed co'py in captivity). Checking the inspection requirements, I note that volumetric (RT or ' T)is specified. Aside J
from the materials / welding issues, we seem to be at cross purposes with the as-yet unendorsed code.
Perhaps we should ask for clarification of intent from NMSS? At any rate, I am still revising wording on PT (as before, decided it isn't all bad, but it still is dependent on critical flaw size). In related experience, Larry Campbell (another knowledgable individual from inspection branch) says that he used to oversee welds (electrical penetrations in containment) very similar to the cask closure welds, and they used UT for these STAINLESS STEEL welds. This gets more interesting all the time. Geoff CC:
