There are over 20 decommissioning nuclear power plants in Japan, and the number will keep to increase in the future. Some equipment in decommissioning plants have to be kept the function until the end of the decommissioning. It is expected to be around eighty years from plant construction. In such a situation, the Aging Management Program (AMP) for the decommissioning plants has not been established. In this paper, we propose new AMP for the decommissioning plants in Japan based on some issues, using Risk Monitor to solve the difference of the risk information to the operating plants.
