After more than 30 years of successful operation the Embalse Nuclear Power Plant has started the refurbishment for the Life Extension Project. Pressure Tubes and other main components of the Primary Coolant System will be replaced. CANDU Fuel Activities during the 2013-2015 period were strongly influenced by the reduced utilization of the Embalse reactor as a result of the preparation of the Power Station for the LE works The main objectives of Fuel Engineering activities during this period were oriented to reduce the fuel production costs, to increase fuel behavior knowledge and to improve some specific QC aspects like the characterization of the structural stability of the fuel pellets. Some new acceptance criteria were developed in this field. At the Embalse NPP, different specific activities were done in order to storage new and irradiated fuel according to the plant configuration status. Along with this some improvements in transportation are in progress. The fuel performance has been consistent with previous years showing the maturity of the nuclear system which is evidenced year after year by parameters like the failure rate and the average fuel discharge burnup. These parameters show that the design and fabrication improvements adopted in previous years had no adverse effect on the on-service performance of the fuels.
