| Title | Inadequate Evaluation of Combustible Material Control Fire Protection Program Change |
| Description | The inspectors identified a Severity Level IV, non-cited violation (NCV) of Browns Ferry Nuclear Plant (BFN) Renewed Facility Operating License Conditions 2.C.(13), (14), and (7) for Units 1, 2, and 3, respectively, and an associated finding of very low safety significance (Green) for the failure to perform an evaluation of the impact of a change to the Fire Protection Report on the fire protection license conditions, as directed by the licensees procedure, FPDP-3, Management of the Fire Protection Report, Revision 3. The failure to adequately evaluate the impact of the change, which permitted the use of fire retardant treated wood materials as transient fire loads in safety related plant areas without further approval, resulted in the implementation of a change to the Fire Protection Program (FPP) that could have adversely affected the ability to achieve and maintain safe shutdown. The licensee also failed to submit the FPP change to the NRC for review and approval prior to implementation which impacted the ability of the NRC to perform its regulatory oversight function. The licensee entered the issue into their corrective action program (CAP) as problem evaluation report PER 812091 and issued an operations Fire Protection Section Instruction Letter to require all wood products to be evaluated when left unattended in any plant fire area. The inspectors determined that this finding was more than minor because if left uncorrected, could become a more significant safety concern. Specifically, if the licensee does not limit transient fire loads (including fire retardant treated wood) to below the capability of suppression systems or fire barrier ratings for a specific fire area as evaluated by the stations fire hazard analysis, a fire could spread to other fire areas and affect the ability to achieve and maintain safe shutdown in the event of a fire. The finding was evaluated using IMC 0609, Attachment 4, Initial Characterization of Findings, issued June 19, 2012, for Mitigating Systems, and IMC 0609, Appendix F, Fire Protection Significance Determination Process, issued September 20, 2013, and the inspectors determined the finding was of very low safety significance (Green) because the reactor would have been able to reach and maintain safe shutdown conditions under actual fire loading conditions. The SDP, however, does not specifically consider the regulatory process impact. Thus, although not related to a common regulatory concern, it is necessary to address the violation and finding using different processes to correctly reflect both the regulatory importance of the violation and the safety significance of the associated finding. The traditional enforcement violation was evaluated using the NRC Enforcement Policy, dated January 28, 2013, revised July 9, 2013, and the inspectors determined the violation was SL-IV per Section 6.1.d.2 of the Enforcement Policy, because the associated finding was evaluated by the SDP as having very low safety significance (i.e., Green). The inspectors determined failure to obtain prior NRC approval for fire protection program changes was similar to violations of 10 CFR 50.59 for enforcement purposes. No cross-cutting aspect was assigned to this finding because the cause of the finding was not indicative of present licensee performance, since the change to the Fire Protection Report occurred in 2003. |
