| Title | Procedure AOI-30.2 C.36, Fire Safe Shutdown Room 737-A1A, Non-feasible Operator Manual Action |
| Description | The inspectors identified an NCV of Technical Specification 5.7.1, Procedures, for the licensees failure to maintain a plant procedure to ensure that an operator manual action for fire safe shutdown (FSSD) could be feasibly performed under the current physical plant configuration. Specifically, post-fire safe shutdown procedure AOI-30.2 C.36, Revision 3, contained instructions for an operator manual action for FSSD that could not be feasibly performed following implementation of a plant design change. The licensee took immediate corrective action to install a temporary scaffold as a compensatory measure. The licensee entered this issue into the corrective action program as PER 356563 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 the procedure step in question was not a time-critical step. The cause of the finding was directly related to the cross-cutting aspect of Work Activity Coordination in the Work Control component of the area of Human Performance, in that the licensee failed to appropriately coordinate work activities, consistent with nuclear safety, to ensure that changes to the physical plant configuration would not adversely affect the feasibility of operator manual actions |
