Durability of vitrified highly active waste from nuclear reprocessing


THE future of nuclear power is often said to depend on the development of a satisfactory method for dealing with highly radioactive waste such as the liquid which is produced during the extraction of plutonium from irradiated nuclear fuel. (See recommendation 27 in ref. 1). Much attention is now being given to developing processes suitable for solidifying highly active liquid waste2 and conversion to a borosilicate glass seems the most favourable route. Here we report a recent investigation at Harwell which supports the belief that the installation of a satisfactory full-scale vitrification process will be successfully achieved.
