Description
JRR-4 is a light water moderated and cooled, graphite reflected pool type research reactor using highly enriched uranium (HEU) plate-type fuels. Its thermal power is 3.5 MW. The core conversion program from HEU fuel to uranium-silicon-aluminum (U3Si2-Al) dispersion type fuel (silicide fuel) with low enriched uranium (LEU) is currently conducted at the JRR-4. This report describes about reactivity initiated events analysis for the safety assessment of JRR-4 silicide core which have been carried out as a part of JRR-4 LEU Project. The following four cases for the anticipated operational transients have been selected and analyzed for the safety assessment. 1) Uncontrolled control rod withdrawal from zero power, 2) Uncontrolled control rod withdrawal from full power, 3) Reactivity insertion by removal of irradiation samples, 4) Reactivity insertion by cold water insertion. All analyses have been carried out by a point kinetics computer code EUREKA-2. The results show that all cases meet the safety criteria for anticipated operational transients which have been established for the JRR-4 LUE silicide fueled core. (author)
