| Title | Failure to Properly Implement a Compensatory Fire Watch As Required by the Fire Protection Program |
| Description | A finding with two examples of very low safety significance and an associated non-cited violation of Technical Specification 5.4.1.c was self-revealed when required compensatory fire watches were discovered to have been terminated while the fire systems were still impaired. Specifically, the licensee failed to maintain compensatory fire watches for Fire Zone 3.1-1, Unit 1 Electrical Cable Tunnel, and for Fire Zones 10.1-2, 2B Diesel Fuel Oil Storage Room, and 10.2-2, 2A Diesel Fuel Oil Storage Room, required by procedure OP-MW-201-007, Fire Protection System Impairment Control, and as described in the Technical Requirements Manual (TRM) limiting condition for operations. The licensee entered this issue into their Corrective Action Program (CAP) as Issue Report (IR) 1596029, Fire Watches Missed Due To 1DSH120 Installation, and IR 1603889, Fire Watch Suspended Prematurely in Diesel Oil Storage Tank Room. The inspectors determined that this finding was more than minor in accordance with IMC 0612, Appendix B, Issue Screening, because the finding was associated with the Initiating Events cornerstone attribute of Protection Against External Factors (Fire) and adversely affected the cornerstone objective of limiting the likelihood of those events that upset plant stability and challenge critical safety functions during plant operations. Specifically, required fire watches established as compensatory measures should have been maintained for the duration of the work activity so that the sites ability to promptly detect and suppress a fire would be maintained. The inspectors evaluated this issue in accordance with IMC 0609, Significance Determination Process, Attachment 0609.04, Initial Characterization of Findings. In Table 3 of Attachment 4, SDP [Significance Determination Process] Appendix Router, the inspectors answered Yes to Question E.2, Does the finding involve:...(2) Fixed fire protection systems....? Therefore, the inspectors continued the risk evaluation using IMC 0609, Appendix F, Fire Protection Significance Determination Process. Due to the equipment located in each of the affected fire zones, the two examples were evaluated independently. The first example screened as Green using the questions under Task 1.4.2 for fixed fire protection systems. For the second example, a Senior Reactor Analyst (SRA) performed a quantitative Phase 2 evaluation and determined the issue to be Green. The inspectors determined that a principle contributor to the finding was that the organization did not implement a process for planning, implementing, and executing concurrent work activities that ensured the required compensatory actions were maintained such that nuclear safety was the overriding priority (WP.1). As a result, the inspectors assigned a cross-cutting aspect of Work Management (H.5) to the finding. |
