This report is being made pursuant to 10CFThis report is being made pursuant to 10CFR50.72(b)(3)(v)(C), 'Event or condition that could have prevented fulfillment of a safety function needed to control the release of radioactive material.' An employee entered a secondary containment interlock and while the door was closing, another employee opened the other secondary containment interlock door thereby having two doors open. The employee immediately secured both doors in the interlock and notified the main control room supervisor. Both doors in the interlock were open for approximately 10 seconds. With both doors open, TS SR 3.6.4.1.2 was not met. This rendered secondary containment inoperable per TS 3.6.4.1. Reactor Building differential pressure, as observed in the main control room, has remained satisfactory and less than -0.25 inches of H20 at all times. Initial investigation determined that a mechanical interlock for the doors was malfunctioning. Administrative controls have been put in place to ensure the doors remain closed pending repairs to the mechanical interlock.</br>The licensee has notified the NRC Resident Inspector.e has notified the NRC Resident Inspector.  +
