The anticipated costs analysis and benefit items survey against performing the maintenance rule

In this paper, we surveyed the cost and benefit items and evaluated the costs against performing the Maintenance Rule. In the past, only one electric power company had provided the electricity without free competition in Korea. In these days, however, the electric power company was divided into two parts by the sources: atomic and hydraulic generation and thermal-power generation. Therefore, the generation sources that done have competitiveness at the price will be weeded out in the electric power market. Although the preferential goal is on the safe operation at the Nuclear power Plants (NPPs), if too much money is required to maintain or improve the safety of the NPP, the licensee could hesitate to adopt the program related to the safety even though it is a good one. Since the Risk-Informed Applications (RIA) have been using for a plant operation in recent, the condition of a plant might be changed. Therefore, considering the affects of the RIA, a method to keep the capability through the monitoring the maintenance effectiveness has been proposed. However, to perform this, a number of works, continuous collecting data and monitoring the maintenance effectiveness and understanding the reason of degrading capability, should be preceded. Therefore, a lot of man-hour is needed to develop and to manage the application method, and the licensee should pay the costs. Therefore, in the domestic circumstance, it is necessary to evaluate the cost to monitor the maintenance effectiveness. Hence, we are going to examine the cost to perform the MR and its anticipated benefit lists
