Title | Inadequate Fire Area Boundary |
Description | The team identified a non-cited violation of License Condition 2.C.(9), Fire Protection, for the failure to ensure the required separation between fire areas. Specifically, the licensee installed fire barriers on two ventilation ducts which were not in a configuration demonstrated to provide the required three-hour fire-rated separation between fire areas. The licensee entered this issue into their corrective action program as Condition Report CR-WF3-2015-00540 and established an hourly fire watch as a compensatory measure until corrective actions can be taken (Fire Impairments 15-30 and 15-31). The failure to ensure the required separation between fire areas was a performance deficiency. The performance deficiency was more than minor because it was associated with the protection against external events (fire) attribute of the Mitigating Systems cornerstone and it adversely affected the cornerstone objective of ensuring the availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences. The team evaluated this finding using Inspection Manual Chapter 0609, Appendix F, Fire Protection Significance Determination Process, dated September 20, 2013. Both emergency diesel generator rooms were equipped with pre-action sprinkler systems which would limit temperatures near the ceiling around the room exhaust ducts; therefore, the finding screened to Green at Section 1.4.3.C. This finding did not have a cross-cutting aspect since it was not indicative of current licensee performance since this fire barrier configuration was installed in the 1980s. (Section 1R05.02.b) |
