摘要 随着反应堆出口温度的提高,高效的动力转换技术已经成为(超)高温气冷堆的一个趋势。该文在HTR-10、HTR-10GT和HTR-PM研究的基础上,针对更高的堆芯出口温度,对高温气冷堆氦气透平循环的热力学参数进行分析、优化和设计。通过建立高温气冷堆的数学模型和优化模型,结合更符合工程经验的约束条件,确定了高温气冷堆氦气透平循环的2个设计工况点:1)接近目前工程经验的工况点,堆芯出口温度为850℃,继承HTR-10GT氦气压气机和透平的设计经验,循环压比为2.47,循环效率为47.60%;2)略带前瞻性的工况点,堆芯出口温度为900℃,堆芯入口温度为550℃,压气机压比为2.75,此时循环效率为48.92%。该文还基于这2个工况点对高温气冷堆氦气透平循环参数进行设计,将会对未来开发高温气冷堆闭式Brayton循环提供帮助。

Abstract:With gradual increase in reactor outlet temperature, the efficient power conversion technology has become one of developing trends of (very) high temperature gas-cooled reactor. Based on the HTR-10, HTR-10GT and HTR-PM, aiming at a higher reactor outlet temperature (ROT), the paper analyzes, optimizes and designs the thermodynamic parameters of the helium turbine cycle of high temperature gas-cooled reactor. Two proposed operating points are determined by the optimization model combined with the constrints of engineering experience. One of these working points is close to the current engineering experiences, inherited the design experience of the helium compressor and turbine of the HTR-10GT. Its ROT is 850℃, the cycle pressure ratio is 2.47, and the cycle efficiency is 47.60%. Another working point is slightly forward-looking. Its ROT is 900℃, the reactor inlet temperature is 550℃, the cycle pressure ratio is 2.75, and the cycle efficiency is 48.92%. And based on these two working points the HTGR helium cycle parameters have been designed. It would be helpful to develop a closed Brayton cycle coupled with a high temperature reactor in the future.
