A unique nuclear shield design for a high beta ignited tokamak has been completed. Maximum advantage is taken of the shielding properties of the vacuum vessel and coil structures with the remaining space being filled with bulk shielding. The basic unit is an aluminum-bronze casting with integrally cast stainless steel coolant tubes. Each module is fitted for the particular zone around the vessel. The modules are sized to minimize the decay time of induced eddy currents and, for this reason, are insulated from one another. Lifting holes are cast-in as are offsets and alignment pins. Using vertical lifts, this permits easy removal for access to components buried in the shielded zones.
