为了扩大 ２００ ＭＷ核供热堆（ＮＨＲ－２００）的应用范围并改善其经济性，初步探讨了在ＮＨＲ－２００的技术基础上，发展热电联供小型反应堆的可能性。提出了核反应堆实现热电联供的几种可能方案，并用编制的计算机程序对其效益进行了分析；提出了小型热电联供沸水堆ＣＲ－２００的一回路方案设计，用最佳热工水力估算程序ＲＥＴＲＡＮ－０２和编制的蒸发器设计程序对ＣＲ－２００作了初步的一回路稳态热工设计和稳定性分析。结果表明，以ＮＨＲ－２００为基础并作一些改进，有可能发展成为小型热电联供沸水堆ＣＲ－２００，该堆具有比低温供热堆ＨＲ－２００更好的经济性。
In order to expand the application range of the 200 MW Nuclear Heating Reactor (NHR-200) and improve its economy, the possibility of developing cogeneration reactors for small reactors based on the NHR-200 technology has been discussed. Proposed several possible solutions for the cogeneration of nuclear reactors, and analyzed its benefits by the computer program compiled. The design of the primary circuit of the CR-200 mini-combined heat and power (CHP) reactor was put forward. The best thermal hydraulic estimation program RETRAN-02 and the preparation of the evaporator design program on the CR-200 made a primary loop steady-state thermal design and stability analysis. The results show that based on the NHR-200 and making some improvements, it is possible to develop it into a CR-200 mini-combined heat and power water reactor, which has better economics than the HR-200 low-temperature heating reactor.
