Title

Failure to Report a Safety System Functional Failure Per 10 CFR 50.73

Description

A Severity Level IV non-cited violation (NCV) of 10 CFR 50.73(a)(2)(v)(D) and (vii)(D) was identified by the inspectors for the licensees failure to recognize a safety system functional failure of the Unit 1 High Pressure Coolant Injection (HPCI) system and submit a licensee event report (LER) within 60 days. This issue was documented in the licensees corrective action program as Problem Evaluation Reports 177206 and 204364, and subsequently reported as LER 050-259/2009-004. This finding was considered as traditional enforcement because it had the potential for impacting the NRCs ability to perform its regulatory function. However, because this violation was of very low safety significance, was not repetitive or willful, and was entered into the licensees corrective action program, the NRC has characterized this violation as a Severity Level IV NCV in accordance with Section IV.A.3 and Supplement I of the NRC Enforcement Policy. The cause of this finding was directly related to the cross-cutting aspect of timely corrective actions in the area of Problem Identification and Resolution because the licensee failed to address previously identified deficiencies regarding the documentation of safety system mission times in a timely manner P.1(d).
