UNITED STATES 7910250507 NUCLEAR REGULATORY COMMISSION OFFICE OF INSPECTION AND ENFORCEMENT WASHINGTON, D.C~ 20555 IE Information Notice No. 79-31 Date:
December 13, 1979 Page 1 of 1 USE OF INCORRECT AMPLIFIED RESPONSE SPECTRA (ARS)
Description of Circumstances:
Recently, the NRC was informed that, during a review of valve weights in conjuncti-0n with the as-built review for IE Bulletin 79-14 at North Anna
- Unit l, it was discovered that incorrect amplified response spectra CARS) had been used as input to the analyses of some piping on both units 1 and 2.
The reanalyses are being performed by Stone & Webster (S&W), the Architect Engineer for the Virginia Electric & Power Company's facilities. Similarly, Public Service Company of New Hampshire informed the NRC that the wrong ARS were used for the design of some containment supports at their Seabrook units.
The Architect Engineer for these plants is United Engineers & Constructors (UE&C).
The.NRC is currently pursuing this issue in detail with S&W and UE&C to deter-mine the extent of the problem and the generic implications for other facilities.
This Information Notice is provided as an early notification of a possible significant matter. It is expected that recipients will review the informa-tion for possible applicability to their facilities. Specific action has been requested by IE Bulletin 79-14.
This bulletin requires that input to seismic analyses of piping, which includes the use of the correct ARS, be verified against the as-built condition of the plant.
No specific actions are requested in response to this Information Notice.
If NRC evaluations so indicate, further licensee actions may be requested or required.
If you have any ques-tions regarding this matter, please contact the Director of the appropriate NRC Regional Office.
No written response to this IE Information Notice is required.
