摘要:通过对10MW高温气冷堆氮气透平发电装置(HTR-10GT)的堆芯、热交换器和透平压气机组等主要设备的数学建模和程序编制,初步建立起了一套模拟该装置瞬态特性的伤真程序,通过对该装置于5s时刻堆内引人0.1$阶正反应性引发的累急停堆事故的瞬态模拟,初步验证了该装置紧急停堆预案设置的安全性和合理性,证明了旁路快开阅的设计预案具有较大的安全裕度。

Abstract: A dynamic analysis code for this system was developed after the mathematical modeling and programming of important equipment of 1o MW High Temperature Gas cooled Reactor Helium Turbine Power Generation (HTR-1oGT), such as reactor core, heat exchanger and turbine-compressor system. A scram accident caused by a 0. 1 $ reactivity injection at 5 second was simulated. The results show that the design emergency shutdown plan for this system is safe and reasonable and that the design of bypass valve has a large safety margin.
Key words: helium turbine; high temperature gas-cooled reactor; scram; simulation
高温气冷堆(以下简称“高温堆”)采用全陶瓷型包覆颗粒燃料元件,以石墨为慢化剂和堆芯结构材料,以氮气为冷却剂,其主要特点是具有固有安全性和高度模块化。由于堆芯为耐高温的全瓷型结构,高温堆堆芯出口温度可
达950℃甚至更高。利用高温堆产生的高温气体直接推动气体透平发电机组是提高发电效率,发挥高温堆潜力的一个理想选择"。因工程设计、系统布置、控制手段研究等多方面的需要,对此类装置的瞬态模拟成为一个重要的研
