Title | Changes to the Approved Fire Protection Program Without Prior Staff Approval |
Description | The inspectors identified a Severity Level IV noncited violation of License Condition 2.C.(5), Fire Protection, for making changes to the approved fire protection program without the required prior Commission approval. Specifically, the licensee made a change to the Updated Safety Analysis Report that allowed the licensee to violate the requirements of 10 CFR Part 50, Appendix R, Section III.L. Specifically, when the licensee recognized that fire damage could cause a pressurizer power operated relief valve to open long enough to create a void in the reactor vessel, this was documented as acceptable when it was not in compliance with this regulatory requirement. The licensee entered this issue into their corrective action program as Performance Improvement Request 2008-004869. This finding was assessed using traditional enforcement since it had the potential for impacting the NRCs ability to perform its regulatory function. This finding is more than minor since the change required prior staff review and approval prior to implementation and it did not receive the required approval. A senior reactor analyst performed a Phase 3 evaluation and determined this performance deficiency was of very low risk significance. In accordance with the guidance in Supplement I of the Enforcement Policy, this issue is considered a Severity Level IV noncited violation because it is of very low risk significance. This finding had a crosscutting aspect in the area of human performance associated with resources because the licensee failed to maintain long-term plant safety by maintaining design margins. Specifically, the licensees choice to allow reactor vessel head voiding during an alternative shutdown in lieu of restoring the plant to compliance with the requirements of 10 CFR Part 50, Appendix R, Section III.L constituted a reduction in safety margin H.2(a) (Section 40A5.3) |
