Optimization of Equipment Maintenance for Nuclear Power Plant

Based on the analysis of the features of equipment maintenance for nuclear power plant,pre-ventive maintenance repair models were established in this paper.At the same time,considering the equip-ment of nuclear power plants,a detailed quantitative study on costs resulted from maintenance and failures was carried out.Finally,the decisions and the corresponding changes of preventive maintenance cycle were discussed with the changes of the failure probability and maintenance costs,and the maintenance cycle change curve was given.
