LESSONS LEARNED FOR SPACE SAFETY FROM THE FUKUSHIMA NUCLEAR POWER PLANT ACCIDENT

摘要

On March 11 2011, Tohoku Region Pacific CoastrnEarthquake hit Japan and caused the devastating damage.rnThe Fukushima Nuclear Power Station (NPS) was alsornseverely damaged.rnThe Japanese NPSs are designed based on the detailedrnsafety requirements and have multiple-folds of hazardrncontrols to the catastrophic hazards as in space system.rnHowever, according to the initial information from thernTokyo Electric Power Company (TEPCO) and thernJapanese government, the larger-than-expected tsunamirnand subsequent events lost the all hazard controls to thernrelease of radioactive materials.rnAt the 5th IAASS, Lessons Learned from this disaster wasrnreported [1] mainly based on the “Report of the JapanesernGovernment to the IAEA Ministerial Conference onrnNuclear Safety” [2] published by Nuclear EmergencyrnResponse Headquarters in June 2011, three months afterrnthe earthquake.rnUp to 2012 summer, the major investigation boards,rnincluding the Japanese Diet, the Japanese Cabinet andrnTEPCO, published their final reports, in which detailedrncauses of this accident and several recommendations arernassessed from each perspective.rnIn this paper, the authors examine to introduce thernlessons learned to be applied to the space safety asrnfindings from these reports.
