Dear Mr. McEwen:
Enclosed please find two attachments that are pertinent to the forthcoming meeting on the intergranular cracking of core spray safe-and in Nine Mile Point Reactor.
The first attachment is a paper, "Intergranular Corrosion Cracking of Type 304 Stainless Steel in Water-Cooled' Reactors." This paper reviews published literature with respect to:
(a) numerous instances of intergranular corrosion cracking of Type 304 stainless steel in water-cooled reactors (b) the various corrosion studies on intergranular cracking (c).the proposed mechanism on intergranular corrosion cracking
~
The second attachment is a memorandum, "Information Needed on Intergranular Corrosion Cracking." This memorandum reviews (a) recent reactor component failures and safe-end status
