Method for obtaining a solution of nuclear fuel not readily dissovable, especially of PuOhd 2 or (U/Pu)O2 mixed oxide

摘要

Not readily dissolvable nuclear fuel is dissolved in an airtight closed vessel or autoclave. Nitric acid is evaporated and condensed in the vessel and the nitric acid condensate trickles over the nuclear fuel disposed outside of the nitric acid undergoing evaporation.
