For aged power plants in Japan, the life extension beyond the original design lifetime with retaining the safety and cost-effective is needed. Therefore it is important to minimise the risk and maintenance cost to keep operating the plants until the plants become uneconomic or unsafely. Life-Cycle Maintenance (LCM) is proposed for optimising maintenance plan with reliability in the life of the plants. Risk Based Maintenance (RBM) is included in the LCM to assess the risk of components in the plants. Life Cycle Cost (LCC) and the investment assessment may be also conducted to decide the most cost effective maintenance strategy, if several maintenance strategies are proposed in RBM. In this paper, concept and an application of the LCM are described to optimise maintenance plan in the lifetime of a plant. It was found that the LCM is quite useful method to plan the most cost effective maintenance strategies in the lifetime of the plant.
