| Title | Adverse Changes to the Fire Prottection Program Involving Inadequate Control of Transient Combustibles |
| Description | The inspectors identified a Severity Level IV Non-cited Violation (NCV) of the North Anna Power Station, Unit 1 and Unit 2 Renewed Facility Operating Licenses, NPF-4 and NPF-7, Condition 2.D, Fire Protection Program (FPP) for making a change that adversely affected their ability to achieve and maintain safe shutdown. This led to inadequate controls of transient combustibles. The licensee initiated condition reports CR342754, Failed to submit request for transient fire loading in U- 2 safeguards, CR 397441, Appendix R fire wrap in Unit 2 Containment, and CR 396368, Appendix R fire wrap in Unit 1 Containment. The inspectors determined that the changes to the FPP involving the control of transient combustibles was a violation involving traditional enforcement because it impacted the NRCs ability to perform its regulatory function. The finding was determined to be more than minor because the relaxation of transient combustible controls described in the revisions to VPAP-2401, constituted a change which adversely affected the licensees ability to achieve and maintain safe shutdown in the event of a fire. This violation is characterized at Severity Level (SL) IV in Supplement I of the NRC Enforcement Policy, in that actual fire did not occur, and the potential consequences were limited given that defense in depth was maintained with the existence of automatic fire detection and suppression capability and the availability of fire response teams. Although the licensee failed to meet regulatory requirements that have more than minor safety or environmental significance, the inspectors were unable to confirm the introduction of excessive transient combustibles into the plant other than the problem identified on July 27, 2009. This lack of information was due to the licensee FPP changes that did not require a permit for evaluation and documentation. Because the issue is in the licensees corrective action program as CR382725, this violation is being treated as an NCV, consistent with the NRC Enforcement Policy. This violation was not screened for associated cross-cutting aspects because it dealt with traditional enforcement |
