TESTING OF ENDF/B-4 WITH GCFR DESIGN CODES THROUGH ANALYSIS OF CRITICAL EXPERIMENTS

摘要

This topical report describes the data testing activities for Version IV of the Evaluated Nuclear Data File which were carried out at General Atomic Company. A total of six selected benchmark critical assemblies were analyzed using General Atomic design methods. Calculations of derived parameters such as eigenvalues, reaction rates, and central worths were compared with calculations made by other agencies. Close inspection of spectral indices indicates possible methods for code improvements. Adequacy of Version IV data is discussed.
