Abstract

Recycle of regenerated uranium and plutonium fuel in thermal reactors REMIX -REgenerated MIXture of U, Pu oxides REMIX is prepared directly from the mixture of uranium and plutonium recovered in the course of SNF reprocessing and corrected with natural enriched uranium with 235 U content about 16-17%.REMIX fuel allows multiple recycling of all the amount of uranium and plutonium recovered from SNF at 100% charging the core of VVER-1000 reactor with this fuel.Composition of different types of nuclear fuel for thermal reactors: 1. Uranium oxide (3.5 -4.5 % 235 U + 238 U)single cycle, processed 2. MOX (5 -7 % 239 Pu + 238 U)single cycle, recycling with restrictions
