JNC reflected on the fire and explosion incident of the bituminization facility and decided to evaluate on the safety of TRP voluntarily. This evaluation has included three activities, that is, (1)evaluation on the prevention system, (2)evaluation on the mitigation system, (3)confirmation on the method of the criticality safety analysis and the radiation shielding analysis. This report describes the results of the evaluation on the prevention system of the TRP's processes. We used HAZOP and FMEA to pick about 4000 abnormal conditions of each process up and selected about 700 abnormal transients. We estimated on a progress of all abnormal tansients and confirmed proprieties of prevention systems. We will reflect these results to improvement of system and operation manual and to education, training for stuffs and operators.
