[en] The radiation migration equivalent activity of the actinide wastes formed in the equilibrium state of the closed fuel cycle of the BREST-300 reactor is calculated. The permissible part of the uranium-plutonium nuclear fuel cycle wastes contains in %: Th, Pa, Bk, Cf 100, U 1, Pu 0.1 in the beginning and 0.01 in the end of the nuclear power action, Am 0.1, Cm 0.1 - 1, Np 20 - 30 in the end of the period of the nuclear power action and 100 - in the beginning and in the middle of the period. The procedures of the nuclear fuel cycle effecting on the management with the long-lived components of high-active wastes are demonstrated
