If a beam-driven D--T tokamak reactor is operated at the maximum density allowed both by pressure limitation and by 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, B/sub tmax/ equals 15T, W/sub beam/ = 200 keV, Q approximately 1.0, maximum wall loading is about 5 MW/m$sup 2$. (auth
