Thermalhydraulic Safety Characteristics Of CANDU ... - Canteach

Loop Isolation for LOCA eventsλλλλDuring some accident scenarios, loop isolation is initiated (forexample in LOCA events were a break occurs in the reactorheaders)Isolation of the two separate loops occurs after the loopisolation signal is received (i.e., detection of a LOCA)By separating the two loops from each other, then only half thecore is affected by the breakForced circulation before the pump trips and thermosyphoningafter the pumps trip provide adequate fuel cooling in the intactloop24-May-01 CANDU safety - #4 - Thermalhydraulics.ppt Rev. 0 15
