Sažetak
Historically, one of the major obstacles during nodalization development was related to the memory restrictions of RELAP5 code. New versions of the RELAP5/MOD3.2 code significantly increased code capacity regarding number of nodes or level of nodalization detail, and opened space for new modeling approaches. This article presents the assessment of detailed, sliced discretization approach based on the transient analysis performed with the RELAP5/MOD3.2.2gama computer code. Both analysis are related to the experiments (tests 9.1b and 6.2tc) performed in the BETHSY integral test facility. Comparative assessment includes experimental data, calculated results from previously developed nodalization for RELAP/MOD2 (and adopted for RELAP5/MOD3.2) and the new more detailed “sliced” nodalization.
