ANAL Y:SISO F LARGE BREAK LOCA IN THE NPP AP-6111S1E, COND PHASE. Analysiso r large
break LaCA in nucle.lf power plant AP-600 ,vas done by reactor computational simulation using a
computerp rograIn COBRA IV-I. Large bre.1kL OCA is considereda s tile severesht )'Potheticaia ccident
in the prf~ssurizewd ater reactor. 1/8 synlInetricaic ore is used in tIle calculationm odel,a nd peak cladding
temperatl:lreis monitoreda s a LOCA accidentc riteria. To do tIlis analysis,i t was required such system
data during tIle transient condition from the Westinghousec alculation. Calculation results of peak
claddingt emperatured uring LOCA is 1500"Ft,h is calculations ho,vedt hat there is difference< 15%, vitIl
