Two accident scenarios with a steam generator ~ube rupture and loss of secondary heat sink in the Kr~ko NPP have泵阀技术论坛 (兰泵论坛)http://www.lanbeng-pump.net
been analyzed. The analyses have been performed with RELAP5/MOD2 computer code on a VAX-8650. In the first
泵阀技术论坛 (兰泵论坛)http://www.lanbeng-pump.netscenario, availability of one HPSI pump was assumed, combined with loss of secondary heat sink, following the total转载请注明出处：http://www.lanbeng-pump.net
loss of off-site power soon after identification and isolation of the ruptured SG. In the second case, the accident was
泵阀技术论坛 http://www.lanbeng-pump.netmanaged by only two centrifugal charging pumps. Lc, ss of all off-site power, causing loss of secondary heat sink, was

The symptoms of the accident led the operator into the feed-and-bleed procedure in both cases. The procedure转载请注明出处：http://www.lanbeng-pump.net
instructs the operator to cool down the p!ant by injecting cold water from the HPSl system directly into the primary泵阀技术(论坛)http://www.lanbeng-pump.net
system and discharging it through the pressurizer relief valves. In the second case, when no HPSI flow could be泵阀技术论坛 http://www.lanbeng-pump.net
