游泳池反应堆新型综合控制系统的研制工作已完成。它由国产高抗干扰集成电路(HTL型)为基本元件组成。为确保安全,对新保护系统进行了可靠性分析和计算。运用马尔科夫状态转移方程分析了表决系统的逻辑结构,确定采用“2/4”的局部符合逻辑,对新保护系统进行了“故障树”分析。建立了“拒动”和“误动”两棵故障树,
The development of a new integrated control system for the swimming pool reactor has been completed. It consists of domestic high-impedance integrated circuit (HTL type) as the basic components. To ensure safety, the new protection system was analyzed and calculated for reliability. The logic structure of the voting system is analyzed by using the Markov state transition equation. The local coincidence logic of “2/4 ” is determined and the “fault tree” analysis of the new protection system is carried out. The establishment of the “refused to move” and “misoperation” two fault tree,
