Comparison of different variants of ATWS type accident calculations by means of the ATHLET and RELAP codes
Description
The results of thermal hydraulic analyses of anticipated transients without scram (ATWS) served as the basis for the new Emergency Operating Procedures for WWER-440/V-213 reactors. Because of the differences in the behavior of parameters in the calculations by the ATHLET code (for the Dukovany NPP) and by the RELAP code (for the Bohunice V2 plant), the major parameters in selected calculations were compared and the differences were explained on graphs. The starting calculations, in which no operator intervention was taken into account, were used for the comparison. (P.A.)
