A study was made to determine variation in construction costs for biological shielding vs. changes in radiation levels and exposure to personnel working around a reactor. The study is based on a hypothetical production type reactor; however, various assumptions have been made to simplify and clarify the analysis. These assumed conditions may be more applicable to those related to an industrial power reactor. Comparisons are made based on the cost of constructing a biological shield that will reduce the radiation level to 1 mrem/hr at the outside face of the shield, a conservative criterion which is ofien used. Estimates of comparative costs are made for radiation levels higher by factors of 10, 50, and 100. Comparative cost estimates have also been made for biological shields made of less costly construction materials than in the assumed basic shield. The analyses primary biological shield, in the building size, in the secondary shielding walls, and in the tubings, etc. In a reactor, such as the assumed hypothetical reactor, the reduction in cost, if the radiation levels were allowed to be increased by a factor of 10, was estimated to be 7,000 or 10.3% of the 308,000 total costs of the primary biological shield. The possibility of cost reductions was analyzed in relation to the computed radiation levels in the areas around the reactor, and the expected exposure to the individuals working in these areas.
