| Title | Potential Missile Hazards from Unrestrained Equipment Near the 345-Kilovolt and 120-Kilovolt Switchyards |
| Description | The inspectors identified a finding of very low safety significance for the licensees failure to adequately control loose materials near the 345-kilovolt and 120-kilovolt switchyards. Specifically, on September 10, 2014, the inspectors identified numerous loose items, including a flatbed of unrestrained wood, loose wooden pallets, construction cones, and other debris in and around the areas of the switchyards. This condition did not meet licensee-established expectations in its severe weather guidance. Once the condition was identified, the licensee removed the material from the 345-kilovolt switchyard; however, th
removal of items near the 120-kilovolt switchyard was not completed until after severe weather had entered the area, including a tornado watch being initiated at the site. No violation of regulatory requirements was identified. The finding was of more than minor safety significance because if left uncorrected, it would have the potential to lead to a more significant safety concern. Specifically, the loose items could affect proper operation of the switchyard during periods of high winds, potentially causing a loss of the switchyard and a reactor scram. The finding was a licensee performance deficiency of very low safety significance because it: (1) was not a loss of coolant accident initiator; (2) did not cause a reactor trip AND the loss of mitigation equipment relied upon to transition the plant to a stable shutdown; (3) did not involve the complete or partial loss of a support system that contributes to the likelihood of, or cause, an initiating event AND affected mitigation equipment; and, (4) did not increase the likelihood of a fire or internal flooding event. The inspectors determined this finding affected the crosscutting area of human performance and the avoid complacency aspect (H.12) due to the licensees failure to recognize and plan for the possibility of mistakes, latent issues, and inherent risk, even while expecting successful outcomes. Specifically, long-term projects increased the number of loose materials near the switchyards, and the complacency thereof, to a point where licensee personnel did not identify these items as potential missile hazards. |
