NUCLEAR REGULATORY COMMISSION 3
WASHINGTON D. C. 20555 tA.
g, v.....f JAN 6 1980 Docket No.: 50-322 Mr. Andrew W. Wofford Vice President Long Island Lighting Company 175 East Old Country Road Hicksville, New York 11801
Dear Mr. Wofford:
SUBJECT:
REQUEST FOR ADDITIONAL INFORMATION - SHOREHAM NUCLEAR POWER STATION We have recently instituted a program of performing an independent confirma-tory piping analysis for each plant undergoing OL review.
For Shoreham this analysis will be performed by our contract personnel at the Argonne National Laboratory (ANL). The purpose of this independent analysis will be to verify that the subject piping system meets the applicable ASME Cace stress criteria. We do not intend to resolve differences between our calculated stresses and yours unless unusually large discrepancies are found or unless Code criteria are not met.
This program will allow us to verify on a sampling basis that you have correctly modeled your piping, have correctly used your computer codes, and have adequately accounted for the piping's as-built condition.
la order to proceed with our analysis, we will require certain information to be supplied for the chosen piping system. Upon receipt of this informa-tion, ANL will evaluate it to determine if additional information or clarifi-cation is required.
Following the initial review we hope to schedule a site visit to acquaint the ANL personnel with the plant and more specifically the piping system under review. At that time we can discuss the piping analysis with your design engineers and obtain any additional information required.
For the Shoreham Station, the west lead of the feedwater piping inside pri-mary containment, from the reactor vessel to the primary containment penetra-tion, was chosen. (Refer to FSAR Figure 3.6.5A-6)
For this piping system, the following information is requested:
U 93 232 8001240 1
JAN S 1330 Mr. Andrew W. W'offord 1.
piping layout and isometric drawings sufficient to model the system 2.
support drawings with support and hanger spring rates 3.
the piping design specification 4.
valve weights and CG's 5.
appropriate response spectra 6.
appropriate anchor point movements 7.
any design dhange notices not yet incorporated into the piping or support drawings (Later DCN's should be fonvarded as received).
Send the above information to:
Mr. C. K. Youngdahl Argonne National Laboratory Building 301 9700 S. Cass Avenue Argonne, Illinois 69439 As our analysis proceeds, we will also require certain of your analytical results for comparative purposes, such as the ASME Code required Design Reports.
If you have any questions on this matter. please contact us.
Sincerely,
- f.S./x).L1 1p -e L. S. Rf;benstein, Acting Chief Light Water Reactors, Branch No. 4 Division of Project Management cc: See Next Page H93 233
