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 10 Code of Federal Regulations (CFR) 50 Appendix B, Criterion XVI, Corrective Action, for the licensees failure 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 Abnormal Operating Instruction (AOI)-30.2 C.36, Fire Safe Shutdown Room 737-A1A, Revision 3, contained instructions for an operator manual action for FSSD that could not be feasibly performed following implementation of a plant design change. A temporary scaffold which was previously installed as a corrective action compensatory measure was removed without authorization. The licensee entered this issue into the corrective action program as Problem Evaluation Report (PER) 485043. 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, Fire Protection Significance Determination Process, 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 |
