The fuel cycle of the fission molybdenum production

Taking into consideration economy and safeguard regulations the nuclear fuel has to be recycled. It was therefore necessary to develop a technological procedure which permits the recovery of uranium from the waste solution arising from fission molybdenum production. The so-called AMOR facility includes three main parts: (1) the dissolution of an irradiated fuel element of a research reactor, the separation of fission molybdenum and a long-time storage of this fuel element solution, (2) the recovery of uranium from solution by an extraction-reextraction process with tri-n-butylphosphate, and (3) producing the Al/UO2+x dispersion, and fabrication of the new target elements. The content of nuclear material is regularly examined by the proliferation agreement. (author)
