| Title | Failure to Perform a Transient Combustible Evaluation for Storage of Oil in a Safety Related Area in Accordance with the Approved Fire Protection Plan. |
| Description | The inspectors identified an NCV of the Unit 1 Operating License Condition 2.F for the licensees failure to store transient combustible materials in a safetyrelated/ critical area of the auxiliary building in accordance with the approved FPP. Specifically, approximately 38 gallons of hydrocarbon oil was stored inside the entrance labyrinth of the 1B charging pump room 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 predominant combustible material in the area. The licensee took immediate corrective action to remove the drum of oil from the area. The licensee entered this issue into the corrective action program as PER 371383 and PER 380910. 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 affects 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 represents 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 a large quantity of oil in a safety-related fire zone without compensatory measures. |
