基于和睦系统的ACPR1000核电机组保护系统优先级管理系统方案设计

通过梳理DI&C-ISG-04标准和ACPR1000核电机组对优先级管理系统（CIS）的功能要求，参考CPR1000核电机组CIS方案中的经验反馈，分析CIS设计中的诸多难点，提出了一套基于和睦系统（FirmSys）的ACPR1000核电机组保护系统CIS方案。相比CPR1000核电机组，ACPR1000核电机组的CIS方案采用了多种设计手段进行优化，如自主化和国产化设计、更优的防软件共因故障设计、更可靠的在线定期试验设计、模块化及多接口设计、就地功能设计。该设计方案已成功应用于ACPR1000核电机组，运转良好。因此本研究提出的CIS方案切实可行。 

Priority Management SystemSchemeDesign for ACPR1000 Reactor Protection System Based on FirmSys

Standard DI&C-ISG-04 and the functional requirements on priority management system?(CIS) of?ACPR1000 nuclear power unit?are reviewed. Based on the experience feedback from?CPR1000 nuclear power plant,?difficulties in CIS design?are analyzed and a scheme of RPS priority management system for ACPR1000 nuclear power plant reactor based on FirmSys?is proposed. Compared with that of CPR1000 nuclear power station, the CIS?for CPR1000 nuclear power plant is further optimized?such as the localized design based on self-reliance, better prevention of?software common cause failure, more reliable online periodic test, modular design with multiple interfaces, and onsite function design.?and the?design sheme has been?successfully applied in ACPR1000 nuclear power station.. The practice shows that the CIS scheme proposed in this paper is a feasible scheme.
