Comparison of fission-gas effects in a transient overpower test (HUT 5-7A) to FRAS3 code predictions

  • 1. Argonne Natl Lab, Ill

Description

Fission gas has an important bearing on fuel dynamics during reactor transients. In this paper, fission-gas bubble sizes and densities, both within grains and on grain boundaries, are characterized as functions of radial location across the axial midplane of the HUT 5-7A (PNL 9-25) TOP (50 /cent/sub s/) TREAT tested fuel pin. The FRAS3 code, being developed to model fission-gas effects in reactor transients, is applied to analyze the results of this experiment. Comparisons between measured data and calculated results for the HUT 5-7A test are presented to illustrate the observed phenomena and to demonstrate the validity of the modeling approach. 13 refs
