对燃气轮机-模块化氦反应堆（GT-MHR）的余热通过氨-水动力/冷却热电联产系统回收的联合循环进行了详细的运行经济性分析。通过参数调查来评估决策变量对GT-MHR和组合循环性能的影响。然后从第一定律、第二定律和消耗经济学的角度对这些周期的性能进行优化。研究发现，将GT-MHR与氨水循环相结合，不仅提高了GT-MHR的一、二律效率，而且从运行经济性角度提高了GT-MHR的循环性能。结果表明，在以消耗经济学为基础进行优化时，两种循环相结合可使产品单位成本降低5.4%。由于联合循环中的氦气质量流量低于单独使用GT-MHR的氦气质量流量，因此总投资成本仅增加了约1%。
A detailed exergoeconomic analysis is performed for a combined cycle in which the waste heat from the Gas Turbine-Modular Helium Reactor (GT-MHR) is recovered by an ammonia–water power/cooling cogeneration system. Parametric investigations are conducted to evaluate the effects of decision variables on the performances of the GT-MHR and combined cycles. The performances of these cycles are then optimized from the viewpoints of first law, second law and exergoeconomics. It is found that, combining the GT-MHR with ammonia–water cycle not only enhances the first and second law efficiencies of the GT-MHR, but also it improves the cycle performance from the exergoeconomic perspective. The results show that, when the optimization is based on the exergoeconomics, the unit cost of products is reduced by 5.4% in combining the two mentioned cycles. This is achieved with a just about 1% increase in total investment cost rate since the helium mass flow in the combined cycle is lower than that in the GT-MHR alone.
