material de matriz composto de grafita e aglutinantes inorgânicos e apropriados para armazenamento final de rejeitos radioativos, processo para produção do mesmo e processamento e uso do mesmo

摘要

The present invention relates to a matrix material for the safe intermediate and/or final storage of radioactive waste, said matrix comprising graphite and at least one inorganic binder. Known materials do not guarantee that radioactive waste can be safely encased for a period of more than 10 million years. The matrix material and blocks made thereof are suitable for the safe embedding and final storage of radioactive waste for an even longer time than this. Further, blocks made of the matrix material can be easily manufactured with the radioactive waste encased in the blocks.
