The European Commission has recently launched a new initiative dedicated to Nuclear Safety in Central and Eastern Europe called after “Safety of Eastern European Type Nuclear Facilities” (SENUF). SENUF contributes to bring together all stakeholders of the nuclear safety programs for the Technical Assistance to the Commonwealth of Independent States (TACIS) and the Poland Hungary Aid for Reconstruction of the Economy (PHARE): beneficiaries, end users, Eastern and Western nuclear industries, and thus, to favour fruitful technical exchanges and feedback of experience. At present, the main focus of SENUF is the nuclear power plant maintenance as a substantial element of plant operational safety as well as life management. A dedicated Working Group has been established on plant maintenance. 10 members have joined in the starting period. After a thematic introduction the paper discusses the maintenance optimisation general aspects and current activities in the CIS and CEEC, the paper presents SENUF and reports about the first activities developed within the working group One of its major tasks in 2004 was to prepare a status report on advanced strategies to optimise maintenance. Optimisation projects have an interface with the plant’s overall life management program. Today, almost all plants belonging to SENUF members have an explicit policy to extend their service life. Thus, component ageing management, modernisation and refurbishment actions became much more important. Preliminary results of the extended inquiry are already available which show a rather homogeneous propagation of techniques and methods in general. A web-enabled database has been developed to provide maintenance managers and engineers with adequate information on “Advanced and Special Equipment, Tools, Materials and Processes” in order to help them selecting the most appropriate and cost efficient solution for their maintenance needs. Information about the existence, the main parameters of such equipment and the experience of their usage that can be valuable for others facing similar problems, will be shared through easy access by members. Currently, the activity is starting to develop into the area of Reliability-Centred and Risk-Informed Maintenance, taking benefit from cooperation with the IAEA. Further extension of the memberships is expected in the near future.
