All radioisotopes are constantly subject to the processes of radioactive decay until they become stable isotopes.…”

“…g At least some of the thirteen (or so) Russian reactors were similar in principle to the U.S. production reactors, in that they were water-cooled, graphite moderated, and fueled with metallic NU clad in aluminum alloy. [72][73][74] However, these reactors were equipped with additional cooling channels for nitrogen, not helium, flow through the graphite core. Other Russian plutonium or tritium production reactors may have been quite different utilizing heavy water moderation.…”

Reprocessing and/or waste management issues are of concern to the "back end" of the nuclear fuel cycle. Of course, there are a great many "nuclear fuel cycle" scenarios to consider; if not in practice, then at least in theory. The simplest conceptually is the "once through" fuel cycle in which the spent fuel is discarded. The more complex fuel cycle scenarios involve reprocessing spent nuclear fuels and a family of nuclear reactor technologies to accommodate burning and breeding for various military and commercial needs. Therefore, the selection of a specific "fuel cycle" is what ultimately imposes the engineering requirements of the reprocessing and waste management technologies. No one part is independent of the other parts in a fuel cycle flowsheet; all parts should be fully integrated. This paper presents a summary of nuclear chemistry processes, nuclear reactor technologies, associated nuclear fuel types, and the reprocessing technologies that serve the different nuclear fuel types. Comprehending how this series of topics are related to each other is a prerequisite to understanding the requirements of any reprocessing strategy. The summary materials presented here are selective, as opposed to comprehensive. More detailed information on any one subject can be found in the reference materials.
