Abstract

An analytical investigation is made of the effect of radial diffusion on the burn-up of fusion produced 1 MeV tritons in hot deuterium plasmas. A simple and useful expression is obtained for the anomalous burn-up ratio, defined as the predicted burn-up with and without radial diffusion effects. When applied to recent experimental results on JET and TFTR showing anomalously reduced burn-up, a diffusion constant of 0.1 - 0.2 m2/sec is inferred for the high energy tritons.
