Abstract

The PDX (Poloidal Divertor Experiment) tokamak will be the first magnetic fusion device to produce intense neutron fields requiring substantial biological shielding. The basic component of the biological shield for PDX is an existing 81 cm thick, high-density concrete shielding wall surrounding the machine. The principal additional shielding requirement is a roof shield over the machine to reduce air-scattered skyshine dose into the PDX control room and to the site boundary. A roof shield consisting of 50 cm of water in polyethylene tanks was selected to meet design objectives of effectiveness, weight, removability, and cost. The controlling factor on water thickness in the tanks is the gamma-ray skyshine dose at the site boundary. Additional shield doors, thin walls, and plugs are required to satisfy the control room radiation requirement.
