Title | Unit 2 Secondary Containment Inoperable Due to Door Gaps |
Description | TS 3.6.4.1, Secondary Containment, requires secondary containment to be operable during Modes 1, 2, and 3. Contrary to the above, from September 18, 2013, to September 24, 2013, and from October 2, 2013, to October 15, 2013, Unit 2 Secondary Containment had door gaps exceeding the allowable leakage criteria. During periods in which the degraded doors were relied upon for Secondary Containment pressure boundary, the Secondary Containment was inoperable. This violation screened to IMC 0609, Appendix A, The SDP for Findings at Power, Exhibit 3 Barrier Integrity Screening Questions. This violation was determined to be very low afety significance (Green) because the finding only represents a degradation of the radiological barrier function provided for the spent fuel pool and standby gas treatment system. The licensee entered this issue into their CAP as NCR 641834. The license took action to repair the degraded doors, translate the design basis requirements for secondary containment into acceptance criteria for the doors in Engineering Change 93918, Determine Reactor Building Pressure Boundary Door Seal Inspection Acceptance Criteria, and revised Procedure 0PT-34.2.2.1, Fire Door, Pressure Boundary Door, Alternate Safe Shutdown Access/Egress Door, and Severe Weather/Flood Control Door Inspections, to incorporate the criteria for Reactor Building pressure boundary doors. |
