The Fukushima-Daiichi NPP Accident was caused by the wrong people and organization attitude for the nuclear safety. The Comprehens ive RISK is the most important factor to keep the safety for nucar system. However, the activities were based on the compliance only. Nobody consider the risk itself. To improve the experiences on RISK, all of the people and organization should always consid er the risk. The maintenance engineering based on the comprehensive risk will support the improvement of nuclear plant ex...

Maintenance Engineering considering Fukushima-Daiichi Accident

In this study, an alternative method to retrieve fuel debris and MCCI (Molten Corium Concrete Interaction) products in Fukushima Daiichi Nuclear Power Plants is proposed, where geopolymer is used for semi-stabilization of those debris. Facing the realization of this method, the fluidity and the setting time of geopolymer are regarded as one of the problems. Thus, for investigating those properties, slump flow experiment, funnel experiment and viscosity measurement will be done. In addition, the experimen...
