EXTERNAL EVENTS OF RESEARCH REACTOR TO POWER

>

The energy crisis, which has been experienced by Indonesia recently, requires an energy alternative as a part of the solution. Moreover, the nuclear power plant (NPP) as an energy source can be considered as one of the alternatives. The safety standard that has been recognized internationally should be implemented at any time, especially those regarding external events. In Indonesia, there are three research reactors, i.e. Kartini Reactor in Yogyakarta, TRIGA 2000 Reactor in Bandung and GA Siwabessy Reactor in Serpong. Based on these three, Indonesia has gained some experiences in qualification and re-evaluation of research reactors. The experience is valuable in preparing the operation of NPP in Indonesia. This paper addresses the issues in qualification and re-evaluation of research reactors as well as anticipation in qualification of NPP from the point of view of seismic hazard that, in smaller scale, has already been implemented in TRIGA 2000 Reactor, Bandung. The hazard analysis concerning TRIGA 2000 Reactor consists of three aspects, i.e., field investigation, probabilistic seismic hazard analysis (PSHA), and structural analysis. Indonesia’s experience in qualification and re-evaluation of research reactors is essential to be developed and applied in the case of NPP. The concept of qualification is similar to that of research reactor, and the differences lie on the quantitative assignment of performance goal, probability of failure, hazard category, safety and design classes. Key words: seismic hazard analysis, external events, nuclear reactor, nuclear power plant.
