EDF-UTO (unité technique opérationnelle) has awarded the consortium formed by NUVIA and GDES a new contract for decontamination services during refuelling outages covering all French nuclear power plants for the next eight years. This wide-ranging contract will include site-specific surveys and solutions for the decontamination of areas with a high risk of exposure to radiation (“décontamination lourde”). GDES will be responsible, specifically, for underwater decontamination of the floor and walls of the reactor pool. For this purpose, GDES will complement the decontamination tasks carried out by NUVIA by providing EDF with DEMOS underwater decontamination and LD9 submersible filtration equipment.
