Abstract:
After the using of the low-enriched fuel in HFETR, the MJTR can only use the low-enriched fuel. In order to enable MJTR to continue its important role in scientific research, production and technological development, four schemes of low-enriched cores have been designed in this paper, and the analysis of physics, thermo-hydraulics and safety have been conducted. The results of these analyses indicate that, the design of low-enriched cores is able to meet the task requirements, and the safety of the reactor is ensured.
