| Title | Failure to store transient combustible materials in a safety-related/critical area of the Auxiliary Building in accordance with the approved Fire Protection Plan |
| Description | An NCV of the Unit 1 Operating License Condition 2.F was identified for the licensees failure to store transient combustible materials in a safety-related/critical area of the auxiliary building in accordance with the approved Fire Protection Plan (FPP). Specifically, an excessive amount of combustible trash and laundry was stored on the auxiliary building refueling floor. The stored combustible material was approximately two and a half times the allowable limit, and the amount in excess of that limit was stored without an approved transient combustible evaluation, as required by the FPP. As a result, this was an unapproved increase in fire loading due to an increase in the volume of the combustible material in the area. The licensee took immediate corrective action to issue a transient combustible evaluation and then remove the excess combustibles from the area. The licensee entered this issue into the CAP as PER 432883 and PER 455545. The finding was determined to be more than minor because it affected the protection against external events attribute of the Mitigating Systems cornerstone, in that, it affected the objective of ensuring reliability and capability of systems that respond to initiating events. This finding was evaluated using IMC 0609, Appendix F, Attachment 1, and was determined to be of very low safety significance because it represented a low degradation of fire prevention and administrative controls. The cause of the finding was directly related to the cross-cutting aspect of proper work planning in the work control component of the area of Human Performance, in that, the licensee failed to appropriately plan work activities to minimize the risk associated with an excessive amount of combustible trash and laundry in a safety related fire zone without compensatory measures. |
