Abstract

Un procedimiento para desprender productos de fisión volátiles de un combustible nuclear irradiado, que comprende hacer reaccionar aglomerados del combustible nuclear irradiado con un oxidante de óxido de nitrógeno a una temperatura de reacción comprendida entre aproximadamente 325º y 800ºC , durante un periodo de tiempo suficiente para formar un polvo fino, con lo que se desprenden los productos de fisión volátiles.A process for releasing volatile fission products from irradiated nuclear fuel, comprising reacting agglomerates of irradiated nuclear fuel with a nitrogen oxide oxidant at a reaction temperature of from about 325° to 800°C for a period of time sufficient to form a fine powder, releasing volatile fission products.
