Abstract: This paper summarizes some results of the Institute of Energy activities under the SENUF initiative. The SENUF stands for the Safety of European Nuclear Facilities. The purpose of these activities was to prepare the preliminary set of maintenance related performance indicators to be used by nuclear power plants in their self evaluation practice and which can be used also as an objective criterion for benchmarking purposes. To develop a maintenance monitoring system, a broad research was carried out. The objective of the research studies was to analyze the current status in the evaluation of the maintenance effectiveness and efficiency by means of the selection of quantitative indicators. The studies were extended not only to the nuclear industry, but also to other industrial sectors with advanced maintenance strategies and advanced systems for maintenance performance evaluation. As an outcome of work done, quantitative indicators were selected and a maintenance performance monitoring framework was proposed. The proposed framework includes the maintenance performance monitoring system, which defines the hierarchical structure of performance indicators distributed in several hierarchical levels in accordance with the breaking of the maintenance process into the single elements. The system consists of three hierarchical levels. On the top of a hierarchical structure is the Maintenance Excellence, from which the attributes of the maintenance program are developed. Three attributes associated with the excellence of the maintenance program are proposed as a higher level of this structure. They are: preventive character of maintenance, maintenance management and maintenance budget. Using the attributes as a starting point, eight key performance indicators were proposed to cover the key aspects of maintenance. Finally each key performance indicator is supported by a set of specific indicators representing the measurable metrics of the maintenance program. In total forty-three (43) specific indicators were selected to cover all aspects of the maintenance program for nuclear power plants. The results presented in the paper are the initial step in the development of the framework for the monitoring of the maintenance efficiency using measurable performance indicators. The paper provides some recommendations to nuclear power plants for the implementation of the proposed maintenance performance indicators system. These recommendations are based on the experience in nuclear industry, in particular the feedback from the application of IAEA operational safety performance indicators.
