Abstract :
The problems of volumetric neutron source (VNS) creation on a tokamak base with moderate to high aspect ratio (A = 3–4.5) and a multiturn normal conducting (‘warm’) toroidal field magnet system are discussed. Two main variants are analysed: torus major radius R =1.7 m (inner radiation shield thickness Δin = 0.2 m); R = 3m (Δin = 0.7 m). Special attention has been given to the following: stationary current drive realization with beam energy 140–160 keV; the case of plasma disruption impact in comparison with ITER; some engineering aspects of VNS development including the divertor problem and choice of insulation, the TF system and vacuum vessel concept, facility assembling/disassembling.
