Using 6- and 8-tube IRT-4M fuel assemblies in WWR-SM research reactor core
- 1. AS RU, Institute of Nuclear Physics, Tashkent (Uzbekistan)
Description
The WWR-SM reactor at the Institute of Nuclear Physics of Academy of Sciences (INP AS) in Uzbekistan was converted to 6-tube IRT-4M LEU (19.7%) fuel. Presently, INP intends to also use IRT-4M 8-tube FA, and a safety analysis for these 'mixed' (8-tube and 6-tube FA) cores is required by the regulatory authorities. This paper presents results of the safety analysis being performed for the 'mixed' cores. Neutronics analysis (burnup, power distributions and shutdown margin), steady-state thermal hydraulics analysis, kinetics parameters for these mixed cores are discussed in this paper. These results will be used to amend the present SAR. (authors)
