Conference Article: Detailed Analysis Of Pebble-Bed HTR Proteus Experiments With The Monte Carlo Code Tripoli4

Abstract

Within the framework of an IAEA co-ordinated research programme (CRP), high temperature reactor experiments with low-enriched uranium fuel were carried out at the PROTEUS facility of the Paul Scherrer Institute (PSI), Switzerland.. High quality and well-documented experimental data were obtained from 13 pebble-bed arrangements, 9 of them were deterministic loaded core configurations. In this paper a calculation-to-experiment (C/E) comparison of keff values, control rod worths and reaction rates, e.g. conversion ratios, is presented for 2 deterministic HTR-PROTEUS cores. The calculations were performed with the Monte Carlo code TRIPOLI4 in conjunction with the nuclear data libraries JEF2.2 and JEFF3. The agreement between experimental and calculated keff values, reactions rate distribution and the conversion ratios is good, however, the calculations slightly underestimates the worths of the shutdown rods.
