New impurity control methods for tokamak fusion power reactors

PDF Version Also Available for Download.

Description

Two methods of impurity control, a helium retention wall and a limiter/wall/vacuum system, are analyzed as candidates for experimental and commercial tokamak fusion reactors. Models were developed for both of these systems and used to compute the steady-state sputtered impurity and helium concentrations as well as the burn-cycle power performance obtainable with these systems. It has been found that relatively modest requirements are needed, for both of these systems, to obtain a non-impurity limited burn. In addition, power output approaching the beta-limited maximum can be obtained with the limiter system if enough of the particle flux for the limiter can ... continued below

In addition, power output approaching the beta-limited maximum can be obtained with the limiter system if enough of the particle flux for the limiter can be directed away from the plasma.
