EL CABRIL: RELEVANT ASPECTS OF MANAGEMENT LILW treatment, conditioning, characterization and disposal operations began in October 1992 in this nuclear installation. The facility has been designed and constructed to guarantee the absence of any significant impact on human beings and the environment. It is made up basically of a conditioning building, quality verification laboratories, other auxiliary installations and disposal structures, consisting of aligned cells. The operations of a complementary installation at El Cabril started up in October 2008. It is used for the disposal of very low level wastes (VLLW), such as most of those generated during the dismantling of nuclear power plants and special interventions involving the clean-up of land or contaminated facilities. El Cabril centre, as key piece of the National system, offers the robustness and operability needed to assure its safety and efficiency, as well as enough flexibility for its optimization (processes improvement, R&D programme on engineered barriers, …)
EL CABRIL: EVOLUTION IN THE IMPLEMENTATION OF REGULATORY REQUIREMENTS Waste Acceptance Criteria: ENRESA has established WAC related to the safety case for operational and post-closure phases. It also set up characterization, Acceptance and verification procedures Waste Tracking System Periodic Safety Review: El Cabril safety case has been periodically updated using the knowledge gained throughout the different phases of the Project According to CSN standards, nuclear facilities are submitted to a safety review every ten years period. 2 PSR covering the periods 1992-2001 and 2002-2011, have been carried out covering: Operating experience Experience on the aspects related to radiation protection Experience from the application of the WAC methodology Experience in the study of parameters affecting the long-term safety Experience in long-term safety assessment Regulatory changes
