Mr. Boyce H. Grier, Director
Reference:
(a) License No. DPR-28 (Docket No. 50-271)
(b) Letter, B. H. Grier to R. H. Groce, dated April 4,1980, IE Bulletin 79-03A
Subject:
Response to IE Bulletin No.79-03A, Longitudinal Weld Defects in ASME SA-312, Type 304 Stainless Steel Pipe
Dear Sir:
The subject bulletin required all power reactor facilities with an operating l'icense to provide the following infonnation:
" Determine whether SA-312 or A-312, Type 300 Series fusion welded pipe is in use or planned for use in safety-related systems subject to design stresses greater than 85 percent of the Code allowable stresse s.
For the purpose of this check the actual wall thickness of the piping products will be considered adequate if the code requirements for pressure design of tile piping products are satisfied using 85 percent of the maximum allowable stress at the design temperature."
Vermont Yankee has determined that none of the subject pipe is in use or planned for use at our facility in safety-related systcms subject to design stresses greater than 85 percent of the Code allowable stresses.
Since our review addresses the action required in Item 1 of the subject bulletin, no further action will be taken on this issue.
The following information is submitted as an estimate of the manpower expended in the research and response for this Bulletin:
