| Title | Failure to Identify Internal Flooding Deficiencies |
| Description | The inspectors identified a finding for the licensee\'s failure to identify various deficiencies that would increase the severity of postulated internal flooding events in the auxiliary building. Specifically, the licensee did not recognize in-plant conditions that could result in the diversion of internal flood water to both emergency core cooling system pump rooms (e.g., fire main break). This finding has been entered into the licensees corrective action program as Condition Report 2008-0197. This finding was greater than minor because it was associated with the protection against external factors (floods) attribute and affected the mitigating systems cornerstone objective of ensuring the availability, reliability, and capability of systems (including flood barriers) that respond to initiating events to prevent undesirable consequences. Using the Manual Chapter 0609, Significance Determination Process, Phase 1 Screening Worksheet, the issue screened as having very low safety significance because it: (1) was not a design or qualification deficiency that was confirmed not to affect equipment operability; (2) did not represent a loss of safety function; (3) did not represent an actual loss of a single train of equipment for more than its Technical Specification allowed outage time; (4) did not represent a loss of risk significant non-Technical Specification equipment; and (5) did not screen as potentially risk significant due to a seismic, flooding, or severe weather initiating event. This finding had a crosscutting aspect in the area of problem identification and resolution, specifically, the operating experience attribute [P.2 (b)] in that the licensee failed to internalize relevant internal flooding information from other licensees, which contributed to this conditio |
