A low cost shielding system was developed for the Demonstration Tokamak Power Plant. The shielding system was designed with low cost materials to fulfill several functions and satisfy the design criteria. The reference shielding materials are water, ordinary concrete, Fe14Mn2Ni2Cr steel alloy, boron carbide, and lead. The cost of this shielding system is only 3% of the total direct cost compared to 11% in the STARFIRE design.
