ENCLOSURE BELLEFONTE NUCLEAR PLANT UNITS;1 AND 2 INCOMPLETE REVIEW OF DESIGN CHANGE REQUESTS BLRD-50-438/84-41, BLRD-50-439/84-37 NCR BLN CEB 8409 10 CFR 50.55(e)
FIRST INTERIM REPORT Description of Deficiency During a design review of design d1ange reports (DCRs), the analysis section responsible for the rigorous analysis of Bellefonte piping identified three DCRs which may have affected issued piping analyses but were not routed to the section for their review. Per the Bellefonte Design Project (BLP) Engineering Procedure (EP) BLP-EP 44.76, the DCR is defined as the document used to notify the piping analyst of a change to the piping that has the potential of affecting the results of an issued analysis or to notify the analyst of the need to perform a new analysis. In the case of DCRs 1349 and 869, piping modifications which had the potential of affecting rigorously analyzed piping were not reviewed by the rigorous analysis section; in the case of DCR 2760 information in the DCR (which was used by the analysis section) does not agree with the DCR 2760 information issued on the physical drawings.
Interim Progress TVA is currently investigating this problem and is initiating a review of all rigorous analyses to determine if any changes to piping designs that could potentially affect these analyses were made that were not reported to the rigorous analysis section by a DCR.
