Абстракт: Today the nuclear power reactors generally use two types of fresh nuclear fuel – uranium dioxide with different level of 235U enrichment (around 95% of all fuel), and mixed uranium-plutonium oxide (MOX) fuel with its use gradually increasing. These fuels have a different isotopic composition which means spent nuclear fuels’ isotopic composition will be different as well, especially concerning the minor actinides. Minor actinides have disproportional impact on spent fuel’s activity and decay heat. The objective of this article is to calculate minor actinides’ concentrations in uranium and MOX spent fuel of WWER reactor type in order to gather data for assessing MOX fuel use impact on spent fuel management.
