For the gradual RCS depressurization and intermittent accumulator discharge in SBLOCAs, isothermal expansion of the accumulator gas would be more appropriate [48].
SBLOCA Analysis and Comparison of Results Obtained from RELAP5-MV with NOTRUMP Code.
The results obtain from SBLOCA analysis using RELAP5-MV code in graphical form are compared with the Westinghouse results obtained through 10-inch small break LOCA analysis using NOTRUMP code.
The SBLOCA is simulated in one of the cold legs in nonpressurized side of the primary loop, with 10-inch break size.
RELAP5-MV is able to simulate a SBLOCA scenario in a similar manner to NOTRUMP code.
