Due to current social and economical framework, in last years many nuclear power plant owners started a program for the Long Term Operation (LTO)/PLIM (Plant Life Management) of their older nuclear facilities. A PLIM framework requires both a detailed review of the features of the main safety programs (Maintenance, ISI, Surveillance) and a complete integration of these safety programs into the general management system of the plant. Therefore PLiM should address safety as well economics, knowledge management as well as decision making, and provide an overall framework to keep the whole plant in a safe and economically sustainable condition. Moreover, new external factors, such as: large use of subcontractors, need for efficient management of spare parts, request for heavy plant refurbishment programs demand for updated techniques in the overall management of the plant. Therefore new organisational models have to be developed to appropriately support the PLIM framework. In recent years a network of European Research Organisations (SENUF) carried out many R&D tasks aiming at capturing the aspects of the maintenance programs where research is mostly needed and at developing suitable optimised maintenance models. Using the outcome of these initiatives, this paper aims at identifying the technical attributes of the PLIM program more directly affecting the decision for a long-term safe operation of a nuclear facility, and the issues related to its optimal implementation. A comparison of some of the available models is presented and an analysis of the potential impact on safety and non-safety programs is provided in order to support the development of optimised life management models.
