Blowdown (RELAP4/MOD7, Version 2) checkout and demonstration problems
Description
The results are presented of developmental verification of RELAP4/MOD7, Version 2. Version 2 is an interim version of MOD7 designated as the blowdown code. The final version of MOD7, to be released late in 1979, will provide continuous LOCA calculational ability spanning blowdown, refill, and reflood. This preliminary assessment consisted of comparing code predictions with test data as well as exercising the code on typical large plant system models. The analysis consisted of checking code capability in three principal areas: self-initiation, fuel model, and general blowdown analysis. System models for the Semiscale MOD-1, LOFT, THTF, and PBF experimental systems were utilized to provide comparisons between MOD7, Version 2, predictions and test data
