Reactor physics analysis for HANARO core conversion using high density U-Mo fuel

  • 1. Korea Atomic Energy Research Institute, Taejon (Korea, Republic of)

Description

Currently, HANARO is using U3Si/Al fuel of 3.15 gU/cc. To enhance the utilization of HANARO, core conversion using high density U-Mo fuel is studied. Minimal core conversion considered maintains fuel shape and only changes fuel density. U7Mo/AI of 4.0/4.5 gU/cc which has been irradiated at HANARO, and U7Mo/AI of 5.0/4.3 gU/cc for the next irradiation test are considered. Important reactor physics parameters such as linear heat generation rate, neutron flux, and reactivity, are compared. A new core model for U7Mo/Al fuel offers additional 4 irradiation sites. U7Mo/ Al core give cycle length extension of 16% and 27%, but a little bit of neutron flux decrease. The increase of linear heat generation rate in a compact U7Mo/Al core is suppressed by the optimized design of fuel assembly. Reactivity effects of U7Mo/Al core are similar to the current core. Core conversion using high density U-Mo fuel give additional irradiation sites and extension of core cycle without any significant loss
