| 摘 要： | 简要介绍了深圳大学改造后的微型堆双计算机联网闭环控制系统的结构以及在功率控制、安全保护等方面设计时所考虑的安全原则和采取的相应措施.这些措施包括:限制反应堆的后备反应性、采用合适的双控制棒运行方式、机控/手控的停堆与紧急停堆保障、设定了运行限值/保护系统整定值/自动停堆的条件、采用双计算机联网实时监测运行参数与数据共享等,并讨论了可能的事件及其对策.由于对关键的运行参数均采用2套独立的系统进行冗余检测,保证了保护系统的冗余与独立性,提高了控制系统的安全可靠性.

| Abstract: | The configurations of the new closed-loop control system are introduced briefly.The system,served by two computers connected with LAN,is made to control Miniature Neutron Source Reactor(MNSR) which is built in Shenzhen University.The technique measures and design polestars for power control and safety protecting are described in the paper.The measures include the restricting of the built-in reactivity,using right working model with dual control bars,using control-bars dropping system in emergencies,setting the right factors for working/protection/emergencies,and taking the countermeasures for potential risks.The pivotal variables are checked redundantly and could be shared between two computers.This also enhanced the reliability of the system for the reactor. |
