| Title | Flammable Gas Cylinders Stored in Safety-Related Area |
| Description | An inspector-identified finding of very low safety significance and a non-cited violation (NCV) of Technical Specification 5.4.1 was identified on February 8, 2011, due to the licensees failure to establish, implement, and maintain procedures for the fire protection program. Specifically, the licensee failed to implement combustible control requirements prior to storing flammable material in a safety-related area. As a result, a gas cylinder containing flammable material was stored in the D6 emergency diesel generator radiator fan room for 1 week without the required additional fire loading evaluation completed. Corrective actions for this issue included entry of this issue into the corrective action program (CAP), removal of the cylinders from the radiator fan room, and the completion of both a human performance and a causal investigation. The inspectors determined that this finding was more than minor because the presence of the gas cylinders could result in a fire affecting the ventilation system for the D6 emergency diesel generator. The finding was associated with the Initiating Events Cornerstone attribute of Protection against External Factors (Fire) and affected the cornerstone objective of limiting the likelihood of those events that upset plant stability and challenge critical safety functions during shutdown as well as power operations. Using a Phase 2 SDP analysis, the inspectors calculated an upper bound change in CDF of 3.3x10-7, which is consistent with a finding of very low safety significance. The inspectors determined that this finding was crosscutting in the Human Performance, Work Control area, because licensee personnel did not coordinate work activities consistent with nuclear safety, specifically in regard to the need to keep personnel apprised of the work impact and operational impact of the work activities.
