Title | Failure to Maintain Fire Loading Within Allowable Limits |
Description | The inspectors identified two examples of a non-cited violation of Crystal River Unit 3 Operating License Condition 2.C (9), for the failure to adequately evaluate changes to the approved Fire Protection Program. Specifically, in 1999, and 2003, the licensee revised their fire protection program to increase the combustible loading beyond the maximum permissible limits for FA CC-124-116, 480V ES Switchgear Bus Room 3B and FA CC-124-117, 480V ES Switchgear Bus Room 3A, respectively without performing an evaluation to ensure compliance with the approved Fire Protection Program. The licensee initiated nuclear condition reports 461209, and 476342 to address this issue. The finding was more than minor because it affected the reactor safety mitigating system cornerstone attribute of protection against external events (i.e. fire). For both examples the selection of a low degradation rating was supported by screening criteria provided in Inspection Manual Chapter (IMC) 0609, Appendix F, Fire Protection Significance Determination Process as well as IMC 0609, Appendix F, Attachment 2 Degradation Rating Guide Specific to Various Fire Protection Elements. Based on the above criteria, this finding is screened as having very low safety significance (Green) in Phase 1 of the Significance Determination Process. The performance deficiency was not assigned a cross cutting aspect as this deficiency occurred over three years ago and is therefore not reflective of current plant performance. |
