Shielding calculations were performed for the DIII-D facility at La Jolla to independently assess the biological dose from radiation emitted during operation. These calculations for both the fully shielded and bare configurations are in essential agreement with those done by General Atomics. In addition to the basic test problems run by General Atomics, a bare configuration with additional air outside the facility area was calculated. The addition of air to the bare configuration caused the dose at 100 meters from the DIII-D center-line to increase by fifty-five percent. The inclusion of the various elemental constituents in the soil composition may …

Description
Shielding calculations were performed for the DIII-D facility at La Jolla to independently assess the biological dose from radiation emitted during operation. These calculations for both the fully shielded and bare configurations are in essential agreement with those done by General Atomics. In addition to the basic test problems run by General Atomics, a bare configuration with additional air outside the facility area was calculated. The addition of air to the bare configuration caused the dose at 100 meters from the DIII-D center-line to increase by fifty-five percent. The inclusion of the various elemental constituents in the soil composition may change the calculated dose, but will not change the shielding factor nor invalidate the overall conclusion of this report. The overall conclusion is that General Atomics and LLNL results are in general agreement. 5 refs., 11 figs., 5 tabs.
