BWR CDF COE Human Error Maintenance Modeling and Simulation PSA
The purpose of this study is to develop an evaluation method to optimize both cost and risk in maintenance strategy of BWR plant in long-term operation. Plant operation is simulated in a simplified model, and the condition of the components treated in the model are evaluated statistically with Monte Carlo simulation. While Probabilistic Safety Assessment(PSA) methods such as Fault Tree Analy sis(FTA), Event Tree Analysis(ETA), and Failure Mode and Effects Analysis(FMEA) are also used to estimate Core Damag...

Abstract: Outlines of, and the empirical observations from, an action research project aiming at improvement of relationship between nuclear community and the public have been reported in this paper. Ultimate goal of the project is effective reduction of social construct risk of nuclear power plants. As an initial approach to the goal, a proactive information provision scheme has been designed based on the knowledge acquired during our previous attemp t of public communication named repetitive dialogue for...

Cost of Electricity Decision-Making Method Maintenance Strategy Unavailability
In this study, a new simulation method is developed for optimization of maintenance strategy in NPP as a multiple-objective optimization problem (MOP). The result of operation is evaluated as the average of the following three measures in 3 000trials: Cost of Electricity (COE) as economic risk, Frequency of unplanned shutdown as plant reliability, and Unavailability of Regular Service System (RSS) and Engineering Safety Features (ESF) as safety measures. The following maintena nce parameters are considered...

Cost Assessment Contact Cost of Electricity Maintenance Risk Assessment s Nuclear Power Plant
Abstract The purpose of this study is to develop a method for quantitative evaluation of the running cost and safety in a Nuclear Power Plant (NPP). A new model for numerical evaluation is proposed based on the concept where the four issues such as Cost of Electricity (COE), maintenan ce cost, loss by the failures, and several risks are evaluated statistically by using the Monte Carlo simulation. The results show different d ependence on the parameters used in the model. These results would be useful to d...

Maintenance Optimization Modeling and Simulation Probabilistic Safety Assessment
The evaluation method for maintenance optimization in long-term operation of nuclear power plant (NPP) has been proposed by using Probabilistic Safety Assessment (PSA) in general. Possible troubles in the maintenance activities of NPP are modeled and simulated by using Fault Tree with failure rates of components estimated by operating experiences in Japan. The Monte-Carlo simulation has been performed to compare the maintenance strategies such as cycle extension of periodic inspection and overhaul for...
