Dear Mr. Parr:
Enclosed are 40 copies of a report entitled "A Reaction to Cracking of Austenitic Stainless Steel Piping in Boiling Water Reactors."
This report is a revision to a report provided to you on October 18, 1976.
Subsequent to the original issue of this report there have been numerous incidents attributed to Intergrannular Stress Corrosion Cracking (IGSCC).
Based on these incidents, PP5L has modified its position on IGSCC, which included additional design changes at SSES.
For this reason and to provide PP5L's response to your letter of February 15, 1978, this report has been revised and updated.
Very truly yours, N.
