Dear Mr. Keppler:
DOCKET NOS. 50-266 AND 50-301 POINT BEACH NUCLEAR PLANT, UNii NOS. 1 AND 2 RESPONSE TO IE BULLETlH NO. 79-04 My letter to you of May 2,1979, provided a list of Seismic Category 1 piping systems in wnich 1500 lb. Velan check valves are installed and indicated tne piping systems for which re-analysis was required.
Re-analysis of these piping systems las been conpleted and we have determined that modifications to piping systems or pipe supports are not required. A sumary of resultr is providea in tne enclosu"e to tnis letter.
Piping systems were re-analyzed using Bechtel Power Corporation computer code ME-101 and valve weights provided in IE Bulletin No. 79-04.
Pipe support loads from this analysis were comared to original design loads to ensure that each support was acceptable.
In all cases, pipe support loads were less than design.
This cocoletes our response to IE Bullet a No. 79-04.
d Very truly yours, m
V Sol Burstein Executive Vice President Enclosure
