Current Status of Kijang Research Reactor Project

Construction of the full-scale mock-up (Fig. 3) to establish optimized Mo-99 production system has been completed in last year. First hot test for the verification of the process is scheduled in 2018 in HANARO. KAERI's process facility handling of the intermediate-level liquid wastes and reduces purification steps from the Mo-99 production. Additionally, compact chilled carbon column concept has been developed to mitigate xenon emission from the Mo-99 production for CTBT purpose. Cold test runs for the developed fission Mo-99 process have been achieved in full-scale. Hot production test in HANARO is on standby. The hot test of fission moly (FM) target is waiting for the restart of HANARO, a research reactor at KAERI. The activity of 2 target plates after 7 days of irradiation will be 10.84 Ci by MCNP6 calculation. The normal FM target will have 8 plates. The intermediate-level liquid radioactive waste treatment is one of the main design issues in the KJRR facility. About 3 m3/yr of radioactive waste is produced during radioisotope production.
