Experimental tokamak reactor concept design for fusion-fusion hybrid reactor and volumetric neutron source

The paper presents the experiment tokamak reactor for developing a fusion-fusion hybrid reactor and volumetric neutron source (VNS). The machine main parameters are as follows: R = 3.6 m, a = 0.9 m, K = 2, B = 5.5 T and Ip = 5.3–7.0 MA. For the hybrid reactor experiment producing the nuclear fuel Pu, the operation will be a steady state with low Qp, where the neutron source N0 = 0.236 × 1020S−1, the plutonium yield GPu = 100 kg year−1, and the tritium breeding ratio T = 1.02. As a VNS, the reactor will be a multiple-testing experiment tokamak and has N0 = 1.4 × 1020S−1; the first-wall neutron load is 1.35 MW m−2, which is used to clarify the aims of hybrid reactor physics and engineering, to prove the high level waste transmutation by means of hybrid reactor and to test the nuclear components and materials, when the plasma operation is in the case of advanced parameters.
