An overvi ew of the Master plan The cAt project in Dessel A long-term solution for Belgian category A waste MORE INFORM ATION about the cA t proje ct: www. niras-c at.be In 2006, ONDRAF/NIRAS, the body responsible for radioactive waste management in Belgium, began work on developing an integrated project of category A waste surface disposal in Dessel (cAt project). As a result, ONDRAF/NIRAS has been very busy over the past few years. The design of the cAt project is taking shape, the legal framework is being put in place for guaranteeing financing and the planning phase and the necessary licence applications are in the preparatory stages. ONDRAF/NIRAS provides an initial description of all aspects of the cAt project in its Master plan: a unique concept, integrating the Dessel repository into a project with long-term social and economic added value for the region. The Master plan articulates the vision shared by ONDRAF/NIRAS and the local partnerships STORA (Dessel) and MONA (Mol) on the cAt project in March 2010, and is based on the report from the STOLA Dessel partnership (November 2004). This Master plan will further evolve over the coming years. With time, it will be concretised on the basis of detailed implementation plans. It will thus develop into a final Master plan when all sub-projects are ready for implementation. This brochure serves as an overview of the Master plan and aims to provide all interested parties with information about the cAt project. More information about the cAt project and the complete Master plan can be consulted on www.niras-cat.be. I hope you enjoy reading this brochure.

Apart from keeping a close eye on the cAt project itself, the population would also like to be actively involved in other nuclear activities in the area. This has already been achieved today within both partnerships It is no more than reasonable to expect the cAt project to deliver a range of benefits for the local communities. These added values are included in all building blocks of the cAt project and are, thus, inextricably linked to it.

ONDRAF/NIRAS has, therefore, opted for technology that offers the best guarantees in terms of safety, environment and health. In addition, it is taking maximum precautions to also guarantee safety for the entire lifecycle of the facility. As an extra added value for the population, ONDRAF/NIRAS is also launching a health monitoring programme in Dessel and the surrounding areas in collaboration with leading research centres. work.

It is, therefore, a real challenge to obtain the necessary finance so that all of the project elements can be realised for the entire lifecycle of the installation. Who is ONDRAF/NIRAS? ONDRAF/NIRAS, the Belgian agency for radioactive waste and enriched fissile materials, has been responsible for the management of radioactive waste in Belgium since its inception in 1980. The organisation is tasked with effectively protecting the population and environment against the hazards associated with radioactive waste. In 2006, the Federal Government entrusted ONDRAF/NIRAS with the task of developing an integrated surface disposal project in Dessel. This project must provide a long-term solution for all Belgian category A waste. cAt project planning is aiming towards Who is STORA? the installation being operational in 2016. STORA, short for “Studie en Overleg Radioactief Afval Dessel” (Study and Consultation Radioactive Waste Dessel), was established in April 2005.
