Abstract
IAEA^s research reactor data base indicates that ~50% of 225 units of research reactor in the world have been in operation for more than 50 years and about 20% of them are more than 60 years, including research reactors in Indonesia. The latest research reactor in Indonesia is multi-purpose reactor RSG-GAS 30 MW that has been operating for 37 years (Its first criticality was in 1987). In accordance with the regulation of BAPETEN, the regulatory body, to ensure sustainable safe reactor operation, a periodic evaluation on reactor safety should be performed. This periodic evaluation is one technique to evaluate nuclear reactor safety whether the reactor design, the status of the structure system and component (SSC), equipment qualification, component aging, safety performance and operation feedback, safety management and nuclear preparedness program, and radiological impact on environment still fulfil the existing safety criteria. This paper is aimed to describe the strategy and evaluation on the periodic safety review (PSR) of RSG-GAS using the reactor operation report in year 2005 - 2015, which is 10 years as regulated. The results of the reactor operation evaluation based on these data show that RSG-GAS still meets the reactor operation safety criteria and the reactor is allowed to operate until 2030. Henceforth, evaluation on the reactor operation safety for 2016 - 2025 period is necessary. In addition, safety analysis report, aging management program, and the latest operation report are also required.
