The production of water-cooled isotopes is an important application of the CARR reactor. Based on the feasibility study on the production of water-cooled isotopes by CARR, a series of schemes are proposed and preliminary results are obtained. The design optimization calculation of the target from the economic and safety point of view is as follows. 1) Calculation and analysis of water-cooled isotope yield. The accuracy of economic indicators calculation results have a significant impact on the optimization of the program. 2) The Monte Carlo method is used to directly obtain the reaction rate, which greatly improves the accuracy of isotope yield and heat release rate of the target.
