The D&D of SM-1A
With the recent mobilization at the site of the former SM-1A nuclear power plant at Fort Greely, Alaska, the Radiological Health Physics Regional Center of Expertise, located at the U.S. Army Corps of Engineers’ Baltimore District, began its work toward the decommissioning and dismantlement of its third nuclear power plant, this time located just 175 miles south of the Arctic Circle.

Shielding optimization for the Compact Ignition Tokamak baseline test cell building design is performed to minimize the cost. The design is based on iterative calculations using one-dimensional SN models calibrated to the results obtained by coupling a three-dimensional Monte Carlo model to a two-dimensional SN model. These sophisticated models remove most conservative factors in the baseline design. When a low-sodium concrete is used as the base material, the boron concentration and the thicknesses are reduced substantially. The optimal configuration that satisfies all the shielding and structural requirements shows a cost reduction of ∼14% ($4.1 million) relative to the baseline design.
