A non-cited violation (
NCV) was identified for failing to take adequate corrective action for the last
Updated Final Safety Analysis Report (
UFSAR) which did not include all the important information for the standby shutdown facility (SSF), the subject of two previous
NCVs. The
UFSAR did not include that the turbine-driven
auxiliary feedwater (
TDAFW) pump suction condenser circulating water makeup source was isolated by two dc
power-operated valves which open automatically on low pump suction pressure, even though it was important information to demonstrate required system power source and suction supply diversity. This finding is in the licensees corrective action program as Plant Investigation Process (
PIP) M-06-3240. This finding is more than minor because it had the potential for impacting the NRCs ability to perform its regulatory function and had a material impact on licensed activities. The inadequate
UFSAR information had been used in a
10 CFR 50.59 screening that resulted in not performing a safety evaluation when required, to determine whether prior NRC approval was needed. This issue was considered as traditional enforcement and was characterized as a
Severity Level IV. The failure to adequately update the
UFSAR for the SSF was the subject of two previous violations (
NCVs 05000369,370/2004003- 02, and
NCV 05000369,370/2005004-01 for untimely corrective action). The cause of the finding is related to the cross-cutting area of Problem Identification and Resolution because the licensee failed to thoroughly evaluate similar problems such that the extent of condition was considered and the cause resolved to prevent recurrence.
