Abstract EN
Recently, several advanced computational tools for simulating reactor system behavior during real and hypothetical transient scenarios were developed.
The TRAC/RELAP Advanced Computational Engine (TRACE) is the latest in a series of advanced, best-estimate reactor system codes developed by the United States Nuclear Regulatory Commission (US NRC).
Nevertheless, the RELAP5/MOD3.3 computer code will be maintained in the next years.
The purpose of the present study was to assess how the accuracy of Bethsy 9.1b test calculation depends on the US NRC RELAP5 code version used.
Bethsy 9.1b test (International Standard Problem no.
27) was 5.08 cm equivalent diameter cold leg break without high-pressure safety injection and with delayed ultimate procedure.
Seven different RELAP5 code versions were used and as much as possible the same input model.
The obtained results indicate that the results obtained by the oldest and latest RELAP5 versions are in general comparable for Bethsy 9.1b test.
This is very important for the validity of the results, obtained in the past with older RELAP5 versions.
Due to the fact that observation was restricted to Bethsy 9.1b posttest, with its own physical phenomena, this conclusion could be generalized only for scenarios having similar range of the considered Bethsy transient conditions.
