A scenario study on the transition to a closed nuclear fuel cycle using the nuclear energy system modelling application package (NESAPP)

The paper presents the results of a case study on evaluating performance and sustainability metrics for Russian nuclear energy deployment scenarios with thermal sodium-cooled fast reactors in closed fuel cycle. Ten possible are considered which differ shares reactors, including options involving use mixed uranium-plutonium oxide reactors. evolution following is estimated period from 2020 to 2100 based assumptions: annual cumulative uranium consumption, needs enrichment capacities, fabrication reprocessing spent stocks, radioactive wastes, amounts plutonium cycle, accumulated depleted uranium, levelised electricity generation cost. show that system can be significantly enhanced through intensive transition authors have highlighted some issues further considerations, will lead more rigorous conclusions regarding preferred development national system.
