Abstract: Characteristics of the highly-enriched uranium targets of two types and irradiation tools currently used at JSC “SSC RIAR” to accumulate fission 99Ìî are described. The parameters for 99Ìî accumulation in the pool-type reactors are presented. Studies have been performed on possibility to convert 99Ìî production to low-enriched uranium using the existing type targets. It is shown that at the achieved fuel density values of 99Ìî accumulation yield decreases approximately by two times.

Keywords: molybdenum, pool-type reactor, target, irradiation device.
