General Scheme of Research Reactor Mainly for Production of Fission ⁹⁹Mo

On the basis of the analysis for current circumstance and development tendency of research reactor mainly for ⁹⁹Mo production in the world, the design idea of this sort of research reactor was proposed. By the optimization and basic design, the general design parameters of the reactor were analyzed and testified. The evaluation of output activities of ⁹⁹Mo and the analysis of economics were conducted on the basically assumption. It is argued that the economics of this reactor is improved dramatically while the safety is ensured by the analysis.
