On 2/29/2012 at 0905 (CST) during schedule … On 2/29/2012 at 0905 (CST) during scheduled surveillance testing it was discovered that Secondary Containment isolation damper 1VAD017B3 would not fully isolate. 1VAD017B3 was declared inoperable per Technical Specification 3.6.4.2 Condition A and an 8 hour action statement to isolate the affected flowpath via a closed and deactivated damper was entered. While performing subsequent actions to isolate the companion isolation damper, 1VAD017A3, it was found on 2/29/2012 at 1222 (CST) that this damper also failed to fully isolate. This left both Secondary Containment isolation dampers in the same flowpath unable to isolate, and Technical Specification 3.6.4.2 Condition B was entered with a 4 hours action statement to isolate the affected flowpath. This condition is reported under 50.72(b)(3)(v)(C), any event or condition that at the time of discovery could have prevented the fulfillment of the safety function of the structures or systems that are needed to control the release of radioactive material.</br>Further actions to isolate the flowpath were successful and both 4 hour and 8 hour Technical Specification action statements were completed within the required time.</br>The licensee informed the NRC Resident Inspector.ensee informed the NRC Resident Inspector. +
