摘要
在应对数字化反应堆保护软件共因故障的有关问题时,当前国际上普通采取的设计措施为设计一套与保护系统数字化软件处理部分独立的多样式保护系统。为了探索其他可能的纵深防御及多样性设计技术,提出基于两套(假设已满足NUREG/CR6303多样性要求的)核安全级数字化仪控平台构建核电厂保护系统,该系统满足抵御保护系统软件共因故障的要求,具备纵深防御及多样性特征的反应堆保护系统。
Design of an individual diversity protection system independent to the software processing part of reactor protection system is widely internationally when coping with the related problems of software common cause failure for digital reactor protection system. In order to make a research of other possible D3 technology. An additional design scheme is proposed in this paper, that is construct a digital reactor protection system with D3character based on two different digital I&C platforms which are supposed to meet the diversity requirements of NUREG/CR 6303.
