Minor Violation: On June 19, 2016, while … Minor Violation: On June 19, 2016, while operating at 82 percent power, two secondary containment access airlock doors were opened simultaneously during surveillance testing as part of STP 3.6.4.102, Secondary Containment Airlock Verification. The inspectors determined this event was caused by inadequate procedural guidance which directed the user to attempt to open one airlock door while the other door was already open. During this test, the interlock failed because the permanent magnets had rotated and were misaligned. This failure could have been identified without challenging airlock interlock integrity if the second airlock door wasnt held open. The failure to have adequate procedural guidance for testing the secondary containment airlock doors was a violation of 10 CFR Part 50, Appendix B, Criterion V, Instructions, Procedures and Drawings, which requires licensees to have procedures appropriate to the circumstance when performing safety-related activities. In response to this issue, the licensee immediately closed the airlock doors. In addition, the licensee submitted a TS change request to address the concurrent opening of two secondary containment airlock doors. The licensees corrective action program is tracking the TS change as CR 02034076, Secondary Containment Airlock Doors #225 and 228 Both Opened. Screening: The issue screened as minor because all of the questions associated with a minor issue found in IMC 0612, Appendix B were answered No due to the licensee reestablishing secondary containment operability immediately after the second airlock door opened. In addition, the inspectors considered the failure to have an appropriate procedure was less than a Severity Level IV violation in accordance with the NRCs Enforcement Policy. Violation: The failure to comply with 10 CFR Part 50, Appendix B, Criterion V, constitutes a minor violation that is not subject to enforcement action in accordance with the NRCs Enforcement Policy. The disposition of this violation closes LER 05000331/2016001.his violation closes LER 05000331/2016001.
