Experience on Primary System Decommissioning in José Cabrera NPP

After 38 years of energetic production, the first Spanish Nuclear Power Plant in operation, José Cabrera, a 150 megawatt pressurized water reactor (PWR), shuts down in 2006. During the next 4 years, conditioning works are carried out and finally, in 2010, the National Waste Company (ENRESA) assumes the installation ownership in order to perform José Cabrera NPP Decommissioning and Closure Plan (DCP). Primary System Decommissioning belongs to DCP works and its scope includes: Steam Generator, Pressurizer, Refrigerant Circuit Pump and Primary Circuit Piping. All these dismantling activities were carried out on site, including preliminary steps before their removal (SAS installations, pre decontaminations, cutting and segmentations, segregations, etc.) and delivery to media/low activity nuclear waste disposal site.
