.. , "l H.s > , a May 29, 1979 Mr. Boyce H. Grier, Director Office of Inspection and Enforcement, Region I U.S. Nuclear Regulatory Commission 631 Park Avenue King of Prussia, PA 19406
SUBJECT:
IE Bulletin 79-07 RLNRC-0029 Docket No. 50-485
Dear Mr. Grier:
Your letter dated April 14, 1979 forwarded IE Bulletin 79-07 concerning seismic stress analysis of safety related piping. The following information is provided in response to your letter.
The items below are numbered to correspond to the Bulletin action items.
- 1. All of the seismic analyses for safety related piping were performed properly. None of the methods specified in the bulletin were used in the analyses.
- 2. This item is not applicable because proper analysis techniques were used. Computer program listings need not be provided.
- 3. All computer codes used in the seismic analysis of safety-related piping have verified as shown below:
(a) ME 632: Verified using PISOL (EDS Nuclear Inc.),
PIPESD (URS/ John A. Blum and Associates, Engineers), and TPIPE (PMB Systems Engineering Inc.).
(b) ME 101: Verified using ME 632, TPIPE and SUPERPIPE (EDS Nuclear Inc.).
(c) TPIPE: Verified using PISOL (EDS Nuclear Inc.) and ME 632.
(d) BSAP: Verified using ME 101. 27'L 158
( e) WESTDYN: Refer to WCAP 8252, Rev. 1, " Documentation of Selected Westinghouse Structural Analysis 79070204'67
/
ROCHESTER GAS AtJO ELECTRIC CORP. SHEET No.
04TE May 29, 1979 To Mr. Boyce H. Grier 2 Computer Codes", May 1977, which is currently under NRC ceview.
- 4. Because all seismic stress analyses for safety related piping were performed using proper techniques no corrective action plan is necessary.
Sincerely yours, t r.
