The results of neutron-physical studies of a fast reactor with uranium-plutonium-zirconium metallic fuel at the initial state of the transition to a closed cycle are presented. The characteristics of plutonium breeding and accumulation in the fuel-assembly lattices with uranium-dioxide fuel mixed with oxide and metallic fuel are presented. Variants of one-time fueling of the BN-800 core with metallic fuel with low reactivity excess, average burnup 80 MW·days/kg and plutonium accumulation coefficient 1.05–1.07 are examined.
