Spent fuel disposal, actinide transmutation

Abstract

Reutilisation of fissile nuclides after reprocessing in light water reactor VVER-440 with inert
matrix fuel (IMF) is analysed. Development of transmutation assembly, containing two pin
types – with metal molybdenum + PuO2 mixture and with classical UO2 is described. Static
characteristics of five-year VVER-440 fuel cycle with IMF are given. Results of control rod
ejection accident analysis are presented. Necessary VVER-440 IMF fuel improvements are
mentioned.
