INSPECTION RESULTS
Licensee-Identified Non-Cited Violation 71111.05 This violation of very low safety significance was identified by the licensee and has been entered into the licensee corrective action program and is being treated as a non-cited violation, consistent with Section 2.3.2 of the Enforcement Policy.
Violation: The Waterford Steam Electric Station, Unit 3 Renewed Facility Operating License, section 2.C(9), requires that the licensee implement and maintain in effect all provisions of the approved fire protection program. The approved fire protection program as described by procedure EN-DC-161, Control of Combustibles, revision 24, required that continuous administrative fire watches be established prior to the introduction of any non-exempt transient combustible materials into designated Level 1 areas.
Contrary to the above, from March 11 to April 25, 2022, the licensee failed to establish fire watches in accordance with the approved fire protection program. Specifically, the licensee failed to establish continuous administrative fire watches in Level 1 designated areas containing non-exempt transient combustible materials. On April 25, 2022, the licensee entered condition report CR-WF3-2022-03147 into their corrective action program which states none of the required administrative continuous fire watches or hourly fire watches were found on station. These watches were required for transient combustible permits that have been open as early as March 11, 2022, and were still in place that day. The condition report notes four fire areas with Level 1 combustible control zones, as defined in attachment 4 of EN-DC-161, where fire watches were not identified:
- RAB 7, relay room
- RAB 8A, switchgear room A
- RAB 8B, switchgear room B
- RCB, reactor containment building Section 7.5 of EN-DC-161, requires a continuous fire watch to be established in accordance with procedure EN-OP-139, Fire Watch Program, revision 6, as a minimum compensatory action prior to the introduction of any non-exempt transient combustible materials into designated Level 1 areas. The inspectors reviewed this condition report and identified a partial loss of fire detection and suppression from April 14 to 16, 2022, for fire zones RAB 8A and RAB 8B, that did not appear to have appropriate continuous fire watches. The inspectors requested documentation from the licensee to validate that these fire watches were performed. No conclusive documentation was found that demonstrated the fire watches were performed.
Significance/Severity: Green. The inspectors assessed the significance of the finding using IMC 0609.04, Initial Characterization of Findings, and IMC 0609, appendix F, attachment 1, and determined the finding to be of very low safety significance (Green) because the affected areas were protected with automatic detection and suppression.
