A risk-based maintenance (RBM) technique has been generated to optimize inspection and maintenance plans for fossil-fired power plants which will be deregulated in Japan. In the present study, technological advances and problems are considered that have resulted from the application of the RBM to actual boiler plants with operating times exceeding 100,000 hours. Risk is defined as the product of the likelihood of damage in plant components by the consequence due to failure of the components or system. The present study found that the RBM is a useful decision tool for determining inspection priority, mitigation of undesirable risk, extension of the inspection period, and other improvements in maintenance practice. At the same time, serious potential problems are brought out.
