Occupational Exposure: The Role of Circuit Chemistry and Tube Coatings in Reducing the ORE of Advanced Water Cooled Fusion Plants and the Potential Effects of Magnetic Fields

On a conservative calculation for a nonoptimized design, the Safety and Environmental Assessment of Fusion Power (SEAFP) water cooled design (Model 2) was found to have an Occupational Radiological Exposure (ORE) which would be too high by today's standards. This paper describes the investigations which have been undertaken to reduce the expected ORE to acceptable levels. In addition, an investigation on allowable exposure to magnetic fields was carried out.
