Perry Nuclear Power Plant Docket Nos. 50-440; 50-441 Unrepresentative Radiographs for Two Borg-Warner Valve Assemblies
[RDC 79(83)]
Dear Mr. Keppler:
This letter serves as the interim report pursuant to 10CFR50.55(e) on the potential significant deficiency concerning unrepresentative radiographs for two Borg-Warner valve assemblies.
Mr. R. Knop of your of fice was notified on August 16, 1983, by Mr. E. Riley of The Cleveland Electric Illuminating Company that this problem was being evaluated.
This report contains a description of the deficiency, corrective action taken to date, and the method planned to complete our evaluation.
Description of Deficiency During our evaluation of the Borg-Warner valve radiographs performed for resolution of a penetrameter anomaly problem [RDC 73(83)], a comparison was made between the original Borg-Warner supplied radiographs and those radiographs taken by the Magnaflux Quality Services on site. As a result of this comparison, it was determined that the Borg-Warner supplied radiographs for two (2) of the forty-four (44) valves evaluated did not match the radiographs which were performed on site by Magnaflux. The two valves in question are identified as S/N 77821 and S/N 56484. The Magnaflux radiographs showed minor indications which did not appear on the Borg-Warner radiographs.
Corrective Action Taken to Date Nonconformance Reports (NR) TAS 0049 and TAS 0050 were issued against the two valves in question. Further research by Borg-Warner provided a satisfactory justification for the radiographic differences for S/N 56484 but could not provide justification for the differences associated with S/N 77821. The minor indications identified on the Magnaflux radiographs have been evaluated l
)
and are acceptable, so no hardware problem existed for either valve in question.

Mr. Jrmes G. Kappler August 31, 1983 Method Planned for Completion of Evaluation The condition found for S/N 77821 is presently considered to be an isolated instance of one discrepancy and the hardware was found to be acceptable in on-site radiographs. To provide assurance that this is an isolated case, however, a program will be implemented as follows.
Installation radiographs of weld ends of all Borg-Warner Safety-Related valves will be reviewed. Any distin-guishing indications within the base metal of the weld end will be matched up with the-original Borg-Warner Radiographs. Any discrepancies will be documented on individual NRs.
Completion of this review will be after installation of all Class 1 and 2 valves, presently-anticipated as February 1984 for Unit 1 and August 1986 for Unit 2.
Please call if there are additional questions.
Sincere
