{{#Regex_clear:At 1308 CST on January 20, … {{#Regex_clear:At 1308 CST on January 20, 2016, the main control room received an alarm that the containment building (VR) ventilation system continuous containment purge (CCP) exhaust fan (1VR07CB) tripped. At 1311 CST, primary-to-secondary containment differential pressure was reported to be +0.411 psid. Technical Specification (TS) Limiting Condition for Operation (LCO) 3.6.1.4, Primary Containment Pressure, Action A.1, was entered due to the differential pressure outside the � 0.25 psid requirement. At 1327 CST, the CCP B subsystem was restarted and at 1339 CST, primary-to-secondary differential pressure was restored to within the limits of TS 3.6.1.4. The cause of the trip of the 1VR07CB is under investigation.</br>This event is reportable under 10 CFR 50.72(b)(3)(ii)(B) as an unanalyzed condition that could have prevented the fulfillment of the primary containment function due to the differential pressure being outside the primary containment initial conditions to ensure that containment pressures remain within design values during a loss of coolant accident. This event is reportable under 10 CFR 50.72(b)(3)(v)(D) as an event or condition that could have prevented the fulfillment of the primary containment function for the same reason.</br>The NRC Resident has been notified. }}on.
