(1) TES ICR No. 5633-10 (March 15, 1983)

(2). TES Trip Report No. 1683 (March 22, 1983) i (3) SWEC EMTP d.22-0, Engineering Mechanics Seismic Report Standard Review Procedure During the original review of the seismic analysis report for Anchor Darling 10" Globe Valve, IE21 M0V-035, the TES reviewer noted that:

(1) Cantilever bending mode not computed (2) Some Class 1 allcwables were used in the evaluation for the

, Class 2 valve (3) Yoke section properties calculations contained mathematical errors LILC0/SWEC in their response stated that:

(1) Vendor technical documents are checked and reviewed for compliance with applicable specifications and documents and the results of the review are reported on a SWEC form delineating additions and corrections required for approvals.

(2) The cantilever mode was computed by SWEC for all 27 Category I valves supplied by vendor. The results of this analysis show all frequencies were above the minimum of 33 Hz.

(3) Vendor used Class 2 allowables for yoke and based non-code bolt material (A574) allowable values on Code procedures (1/4 Su).

2.0 RESOLUTION The Reference (1) disposition raised questions relative to SWEC procedures establishing review methods of vendor calculations and implementation of those procedures relative to Shoreham, and requested certain documents be made available for further TES review.

The Reference (3) procedure provides general guidelines to the SWEC reviewer of vendor seismic qualification reports. A checklist (Form 5040.51B) provides broad guidance for items to be checked, such as, consistency with specification requirements, appropriateness of analytical techniques, assumptions, etc. More specific review aspects are determined by the reviewer whose assignment is based on SWEC internal assessment of the reviewers qualifications.

The Reference (2) trip report documents the purpose and scope of the subsequent TES review and summarizes the information obtained. The review seeked to establish whether the " apparent" omission of the cantilever mode frequency check by the SWEC reviewer was indicative of an inherent deficiency in the SWEC design process as applied to Shoreham, which may have directly caused or contributed to the omission.

This subsequent review indicated that such a deficiency does not exist.

TES considers the Reference (3) approach to be sufficient for general application in the design process and not a direct cause of the original finding. However, the circumstances would indicate that an oversight in the specific review aspects occurred by failure to consider and/or record the lower cantilever mode frequency. The significance of this oversight has been assessed in Reference (1) to the satisfaction of TES and this item should be closed.
