Abstract
Método para descontaminar una superficie metálica en un reactor nuclear refrigerado y moderado con agua pesada, donde la superficie metálica está recubierta con uno o varios óxidos metálicos que incluyen radioisótopos, y donde la superficie metálica está en contacto con un refrigerador o moderador de agua pesada, el método comprende uno o más ciclos de tratamiento comprendiendo cada uno un paso de oxidación donde la superficie metálica se contacta con una solución de un oxidante en agua pesada; un paso de descontaminación donde la superficie metálica sometida al paso de oxidación se contacta con un reactivo de descontaminación en agua pesada para disolver el único o los varios óxidos metálicos y los radioisótopos en una solución de descontaminación e inmovilizando los radioisótopos en una resina de intercambio iónico; y un paso de descomposición donde el reactivo de descontaminación en la solución de descontaminación se descompone; y donde el oxidante, el reactivo de descontaminación y la resina de intercambio iónico se proporcionan en forma deuterada y/o están libres de hidrógeno activo. Un reactor nuclear de agua pesada está adaptado para realizar el método de descontaminación.Method for decontaminating a metal surface in a nuclear reactor cooled and moderated with heavy water, where the metal surface is coated with one or more metal oxides that include radioisotopes, and where the metal surface is in contact with a heavy water cooler or moderator, The method comprises one or more treatment cycles each comprising an oxidation step where the metal surface is contacted with a solution of an oxidant in heavy water; a decontamination step where the metal surface subjected to the oxidation step is contacted with a heavy water decontamination reagent to dissolve the single or several metal oxides and the radioisotopes in a decontamination solution and immobilizing the radioisotopes in an ion exchange resin ; and a decomposition step where the decontamination reagent in the decontamination solution decomposes; and where the oxidant, decontamination reagent and ion exchange resin are provided in deuterated form and / or are free of active hydrogen. A heavy water nuclear reactor is adapted to perform the decontamination method.
