摘要
软件验证和确认(V&V)技术对于提高核电站安全级仪控系统的软件质量发挥着重要作用。在核安全级数字化控制系统(DCS)中,系统、硬件与软件三者同等重要且密不可分,因此有必要将系统和硬件也纳入V&V的范围。讨论了针对核安全级DCS中系统、软件和硬件的V&V标准体系,提出融合新核安全导则HAD 102/10—2021和新工业标准IEEE Std 1012^(TM)-2016关于生命周期要求的V&V过程模型,并阐述了3类V&V活动之间的交互关系及系统V&V和硬件V&V中的重点任务。该研究成果在自主化核安全级仪控平台和睦系统的研制及某核电站DCS工程典型项目的成功应用中,取得了良好效果。其满足核安全级DCS的质量控制需求,同时也符合HAD 102/10—2021的新监管要求。该研究为我国核行业实施系统和硬件的V&V提供了技术借鉴,有助于提升产品安全性和可靠性,也对其他高可靠性领域系统的质量控制有重要参考意义。
Software verification and validation(V&V)techniques play an important role in improving the software quality of safety level digital control systems in nuclear power plants.In nuclear safety level digital control systems(DCS),the system,hardware,and software are equally important and inseparable,so it is necessary to include the system and hardware into the scope of V&V.The V&V standard system for system,software and hardware in nuclear safety level DCS is discussed,and a V&V process model that integrates the new nuclear safety guideline HAD 102/10—2021 and the new industry standard IEEE Std 1012^(TM)-2016 on life-cycle requirements is proposed,and the interation between the three types of V&V activities and the key tasks in system V&V and hardware V&V.The research results have a good effect in the development of an autonomous nuclear safety level instrumentation and control platform rapport system and successfully applied in a typical project of a nuclear power plant DCS project.It meets the quality control requirements of nuclear safety level DCS,and also meets the latest regulatory requirements of HAD 102/10—2021.The study provides technical reference for the implementation of system and hardware V&V in China’s nuclear industry,which helps to improve product safety and reliability,and has important reference significance for the quality control of systems in other high reliability fields.
