| Title | Categorization of Operator Manual Actions as Meeting Appendix R Section III.G.1 versus III.G.2 |
| Description | The team identified a URI concerning the licensees categorization of OMAs as required for Appendix R Section III.G.1 versus III.G.2. The licensees SSA identified a number of FAs as meeting the separation criteria of Appendix R Section III.G.1. The team questioned the basis for categorizing the OMAs as required for Appendix R Section III.G.1 versus III.G.2 for certain FAs in that the FAs had numerous OMAs that appeared to be required to ensure SSD (e.g., FA 9). Appendix R Section III.G.1 specifies that one train of systems necessary to achieve and maintain hot shutdown conditions from either the control room or emergency control station(s) is free of fire damage. OMAs at the specified emergency control stations for III.G.1 compliance are allowed. Prior NRC approval is required to credit OMAs in lieu of spatial separation for III.G.2 compliance. During review of the Appendix R submittals prior to the BFN Unit 2 and Unit 3 restarts, the NRC staff accepted OMAs for certain FAs based on the SSA statements that the FAs met Appendix R Section III.G.1 separation criteria. The licensees January 27, 2009, exemption request included OMAs for III.G.2 FAs only because the OMAs for the III.G.1 FAs were considered to have been previously accepted by the NRC. Consequently, numerous OMAs may not have been included in the exemption request and may not be identified in the licensees corrective action program (CAP) if the OMAs were improperly categorized as being required for Appendix R Section III.G.1 versus III.G.2. The team discussed this with licensee personnel who initiated PER 169491 to address this issue. This issue is identified as URI 05000259, 260, 296/2009007-04, Categorization of Operator Manual Actions as Meeting Appendix R Section III.G.1 versus III.G.2, and is unresolved pending further licensee review of the SSA to determine if OMAs were properly categorized |
