Title | Fire in Pressurizer Cubicle Due to Poor Work Practices |
Description | A self-revealing noncited violation of License NPF-51, Condition 2.C. (6), was identified involving the failure to follow procedures for proper control of ignition sources. Specifically, contract welding personnel failed to deenergize welding equipment and properly secure the welding rod electrodes, resulting in a fire in the Unit 2 pressurizer cubicle inside containment. This issue was entered into the licensee\'s corrective action program as Condition Report/Disposition Request 3170965. The finding is greater than minor because it is associated with the external factors attributes of the initiating events cornerstone 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. Manual Chapter 0609, \"Significance Determination Process,\" Appendix M, \"Significance Determination Process Using Qualitative Criteria,\" was used since the Manual Chapter 0609, Appendix F, \"Fire Protection Significance Determination Process,\" does not address the potential risk significance of fire protection findings during shutdown conditions. The finding was determined to be of very low safety significance by NRC management review because the finding occurred while the unit was already in a cold shutdown condition and the finding did not affect equipment necessary to maintain safe shutdown. This finding has a crosscutting aspect in the area of human performance associated with work practices because the licensee did not ensure supervisory and management oversight of work activities, including contractors, such that nuclear safety is supported H.4(c) (Section 4OA3) |
