Chronology of Callaway MSIV Operability Issues January 23, 2006 February 2005 The licensee completed a new MSL Break accident Analysis Case (Case 1.7). Case 17 considered the plant configuration with one MSIV actuator removed from service. The current licensee bases (CLB), including Technical Specifications (TS), and the accident analysis assumed 141 million BTUs/hr containment cooler duty. Case 17 assumed 155 million BTUs/hr cooler duty. The 155 million BTUs/hr duty was based on additional margin provided by clean, unblocked heat exchanger coils. The new Case 17 concluded the resulting peak containment temperature and pressure was bonded by CLB Cases 6 and 12 (the limiting Cases).
March 2005 Licensee prepared a 50.59 safety evaluation to add the new MSL Break accident Analysis Case (Case 17) to the CLB. The licensee concluded that prior NRC approval was required..
