核反应堆仪控系统软件验证与确认过程研究

摘要

仪控系统通过软件程序和硬件设备对核反应堆进行监测、运行以及安全保护,对核安全具有重要作用. 为保证仪控系统中软件的安全性、可靠性,需要在软件生命周期过程中,开展验证与确认工作. 论述了在核反应堆仪控系统软件开发过程中需要定义的验证与确认阶段,对每个阶段验证与确认的活动、输入、输出进行定义,以指导软件验证与确认工作的有效实施.%The instrument and control system is important for nuclear security operation such as monitoring and operating and protecting the reactor in software and hardware.The safety and reliability of software need to verify and valid in the lifecycle of software.This paper expounds the defined phases of software verification and valida-tion such as the activities, inputs and outputs within the development of instrument and control system software. This can instruct the verification and validation actions.
