Remix NFC: options, timeframe, technical and economic assessment of efficiency

REMIX conception is one of the advance option of NFC for LWR SNF management for U&Pu multyrecycling in existing NPP fleet, which suppose more efficient usage of natural resource and energetic potential in SNF, provide non-accumulation SNF. Three experimental REMIX fuel assemblies, (FA) containing 18 REMIX-fuel elements have been manufactured. Since 2016, they are being irradiated at Balakovo NPP. In parallel, ampules for FA irradiation in MIR research reactor and post-irradiation investigations were manufactured – some of them have already been removed and are being investigated. The next stage is to have references in the full-scale F As fabrication and irradiation. In 2018 there was the start of the safety case development program for REMIX fuel use in WWER-1000. The program includes the development and validation of computer codes for nuclear and radiation safety demonstration. There are plans for the industrial facility for REMIX-fuel fabrication construction. In 2018 the development of investment justification such facility was initiated.
