核供热反应堆热电联产研究是低温堆综合利用开发研究的一个重要方面。为了探索商用供热堆进行热电联产、扩大低温堆的应用领域，提高其年运行因子改善供热堆的经济性，利用５ＭＷ核供热堆（ＮＨＲ－５）为热源，通过其二回路上特殊设计的低压蒸发器和低压两相透平发电机实现核热－电力转换。用冷凝器二次侧的循环冷却水向热网用户供热，实现核供热反应堆的热电联产。结果表明，一体化自然循环式供热堆用于热电联产在技术上是可行的，整套系统表现出极好的运行性能和安全性能。

Investigation on heat-electricity cogeneration with nuclear heating reactor is one of the important aspects of exploitation and research on comprehensive utilization of nuclear heating reactors. The goal of the investigation is to experimentally demonstrate the feasibility of cogeneration with the nuclear heating reactors, raise its annual availability factor, expand its application field, therefore the economic viability of nuclear heating reactors would significantly be improved. The 5 MW nuclear heating reactor (NHR-5) was used as an energy source,and nuclear energy-electricity transformation was achieved with a specially designed low pressure steam generator set in the secondary loop, and a low pressure two phase flow turbine, meanwhile the circulation cooling water from the condenser 'was pumped to the heat grid for house heating. The experiments demonstrate that heat-electricity cogeneration using the nuclear heating reactor with integrated design and natural circulation is technically feasible and the cogeneration system shows excellent operability and safety.
