概要
The construction of the research reactor ‘IRR-3' started for the purpose of development of nuclear technology and first critical was achieved in 1961. A large scale modification was done to meet more de mand from researchers in 1990. So far about operation of JRR-3, there have been no big troubles and JRR-3 has been under stable operation for more than 15 years from the modification. But it is necessary to investigate a maintenance methods considering high aging. On the contrary, it is difficult to keep present maintenance because of the reduction of the budget and staff. In such situation, we should f ind an effective maintenance method which does not spoil safety and reliability. In this presentation, our investigation of the effective maintenance and actual maintenance activities on JRR-3 are shown.
