Belgatom selected by ONDRAF/NIRAS to perform a study about the activation of MDS Nordion cyclotrons concrete in the frame of the assessment of their dismantling cost

ONDRAF/NIRAS, the Belgian Agency for Management of Radioactive Waste and Fissile Materials, is in charge of setting up dismantling plans for several types of nuclear installations in Belgium, including cyclotrons such as the ones owned by MDS Nordion. MDS Nordion, which is located in Fleurus, is a global leader in radioisotope technology, supplying the European market with radioisotopes used to prevent, diagnose and treat disease.

Setting up the dismantling plan of the cyclotrons is necessary to be able to calculate the associated dismantling costs. In order to assess the masses and activities of waste that will be generated during the dismantling operations, a model of the activation of the concrete of the cyclotron must be developed. To perform this modeling task, ONDRAF/NIRAS issued a call for tenders in October 2004.

Belgatom was selected as the successful tenderer by ONDRAF/NIRAS in December 2004. In the selection process, Belgatom’s expertise with the modeling of the activation of the concrete of the reactor buildings of Doel and Tihange NPPs, which was used to assess the dismantling costs of these power plants, has been a significant asset.

The project which is scheduled to last 6 months will be performed with computer code MCNPX, enabling to consider protons and neutrons in coupled mode.
