Estimation of SMART Control & Instrumentation Reliability Via Structured Expert Judgement

智能控制和仪表(SC&I)是一种“智能”控制设备，它使用可编程电子元件来收集和处理数据，以提高性能。该项目将开发一个过程，以生成SC&I的现实可靠性估计，以支持核电站(NPP)的安全案例。民用核电，通过核裂变，是一个安全关键的行业，系统故障可能会导致严重的后果。该项目将有助于确保从安全案例中获得的风险洞察是有效的，并有效地集中资源来改善民用核电站的安全和运营。这有可能减少系统故障，这些故障可能会导致核电站发生事故，影响运营商、公众和环境。关于设备使用的决策过程的改进转化为提高核电厂的整体安全性、效率和可用性。这些因素的任何轻微改善都会带来巨大的经济效益，因为事故的成本很高，发电厂无法使用的成本也很高。除了经济效益，还包括避免事故带来的健康和环境效益，以及英国电网供应安全的逐步改善。

SMART Control and Instrumentation (SC&I) are “intelligent” control devices that employ programmable electronic components to collect and process data to enhance performance. This project will develop a process to generate realistic reliability estimates of SC&I to support nuclear power plant (NPP) safety cases. Civil nuclear power generation, by nuclear fission, is a safety critical industry where failures of systems can lead to severe consequences. This project will help ensure that risk insights from safety cases are valid and resources are focussed efficiently to improve safety and operation of civil NPPs. This has the potential to reduce system failures that could cause an incident at a NPP, affecting the operators, the public and the environment. Improvements in the decision making process about equipment use translate to improvements in the safety, efficiency and availability of NPPs overall. Any slight improvements in these factors have a large economic benefit since the cost of accidents is high, as is the cost of unavailability of a power station. Added to the economic benefits are the health and environmental benefits of avoided accidents, and incremental improvement to the security of supply of the UK grid.
