Lesson Learned Dari Kecelakaan Reaktor Nuklir Fukushima Daiichi Untuk Meningkatkan Mitigasi Reaktor Serba Guna Gerrit Augustinus Siwabessy (RSG-GAS)

Abstract

[ Lesson Learned from the Fukushima Daiichi Nuclear Reactor Accident to Increase RSG-GAS Mitigation ] Indonesia with a geographic area that is relatively the same as Japan and is strongly influenced by the movement of tectonic plate causing Indonesia to be prone of tectonic earthquakes, especially Serpong City of South Tangerang, the location of the Reaktor Serba Guna - G.A. Siwalessy (RSG-GAS) was recorded in a Catalog of Significant and Destructive Earthquake in year 1821-2018, as a risky area of the earthquake. Based on this fact, this study identified and analyzed mitigation efforts carried out to reduce the risk of disaster threats due to technology failure in RSG-GAS. The research method used was qualitatively with descriptive exploratory research design, explores new phenomena and describes according to direct observation of primary data obtained through interviews with resource persons, and secondary data through document studies belonging to resource persons and literature studies. Data validation was carried out with triangulation techniques by conducting data investigations from various sources in the analysis in accordance with the research framework. Mitigation actions have been carried out before the design was arranged, precisely on the determination of prospective reactor site until the current stage of reactor operation. Reactor site evaluation is carried out on aspects of external events (earthquake, geotechnics, meteorology, hydrology, human induce, and dispersion of radioactive substances). The updating of reactor site evaluation form external events is a consideration in RSG-GAS design mitigation, including the simulation the station blackout that has been carried out in the RSG-GAS, to find out the capacity and vulnerability of the RSG-GAS against external hazards that occurred such as in Fukushima Daiichi. External hazards such as earthquake and other hazards has also been promulgated in Indonesian Regulation of Nuclear Reactor Design. To strengthen the capacity of the government and stakeholders it is necessary to revise the Government Regulation to regulate its responsibilities and authority in nuclear emergencies to ensure the safety of the community to create national security.
