| Title | Failure to Adequately Control Energized Temporary Power Sources with Transient Fire Loads |
| Description | An NRC-identified non-cited violation of the Fire Protection Program (FPP) was identified when the licensee failed to evaluate 600V temporary power sources installed in a housekeeping area with approved transient combustibles as required by NSD 313, Control of Combustible and Flammable Material. This issue was entered into the licensees corrective action program (CAP) and corrective actions included immediately removing the transient combustibles from the housekeeping area. The failure to evaluate the energized 600V temporary power sources as an ignition source while located in a housekeeping area with approved transient combustibles was a performance deficiency (PD). The PD was more than minor because it was associated with the Initiating Events cornerstone attribute of Protection Against External Factors - Fire, and adversely affected the cornerstone objective in that a failure of the 600V temporary power source could ignite the transient combustibles causing damage to equipment located in the 1A Diesel Generator (DG) room. The finding was determined to be of very low safety significance (Green) because the transient combustibles did not involve low flash point liquids or self igniting material. This finding was associated with the aspect of appropriately planning work activities by incorporating job site conditions which may impact plant systems, of the Work Control component in the Human Performance cross-cutting area in that the licensee did not consider the effect of energized 600V temporary power cables on transient combustibles in a housekeeping zone. |
