<p>In domestic nuclear power plant, realization of stable operation, improvement of capacity factor, and reduction of maintenance cost are the most important challenge after restart for recovery of investment in safety equipment related to new regulatory requirements, achieving carbon neutral, energy security, and so on. As one of the measures, maintenance optimization for power plant components is mentioned. However, there are few applications of methods for quantitatively evaluating inspection frequency, maintenance methods, and cost for optimization. In this paper, aiming reduction of failure risk and maintenance cost during equipment life, we propose a method for predicting failure risk and maintenance cost during long-term operation by associating each failure rate of initial failure, accidental failure, and wear and tear failure estimated from actual failure cases with equipment operation(operation/maintenance) plan and results.</p>
