If a beam-driven deuterium-tritium tokamak reactor is operated at the maximum density allowed by both pressure limitation and adequate neutral-beam penetration, the 14-MeV neutron wall loading increases approximately linearly with magnetic field or vertical elongation of the plasma. With elongation = 3, Btmax - 15 T (at the coil windings), Wbeam = 200 keV, and Q = 1.0, the maximum wall loading is ∼5 MW/m2.
