The first services carried out at ENUSA were aimed at checking the fuel's behaviour through inspections and measurements of the fuel's most representative characteristics. For this purpose, we developed, together with Tecnatom, the equipment known as SICOM which, thanks to new updates and innovations, is still used in nuclear power plants today. The SICOM equipment family continues to grow to incorporate new capabilities and to meet the most current needs arising from fuel behaviour monitoring programmes and also from its management as irradiated fuel.

In the 1990s, ENUSA began to provide fuel leakage inspection and fuel repair services, and progressively the entire portfolio of services described in the previous paragraphs. In 1995, we founded the subsidiary ENUSA-ENWESA AIE, which works with PWR fuel, of which ENWESA Operaciones and Westinghouse Technology Services (WTS) are partners. We have also developed specific services for BWR fuel with GENUSA. The current equipment we have developed in collaboration with our technology partners and other Spanish companies contains advanced technological solutions.

In recent years, we have been carrying out campaigns in practically all the Spanish plants, in European plants where we supply fuel, and occasionally in other continents, with campaigns in the Angra (Brazil) and Maanshan (Taiwan) plants. Furthermore, in 2007 we signed an agreement between ENUSA and Tecnatom for the rendering of services in China, a market to which we have already exported our experience, technology and know-how.

As a result of all this experience in the provision of fuel services, at ENUSA we are also prepared to carry out the necessary activities for the appropriate management of irradiated fuel. We are currently participating in different plants where activities are carried out to inspect, prepare and classify fuel assemblies for dry storage. With this commitment, we are also developing the technology and processes necessary to support our customers throughout the fuel cycle.
