摘要
本研究的重点是开发核电站 1E 级设备的设备鉴定(EQ)测试设施,强调在设计基础事件(DBE)下确保安全功能的必要性。大韩民国(ROK)已实施国际安全标准来支持大型 NPP 项目,因此有必要开发国内 EQ 测试设施,以减少对国外设施的依赖。为了满足这一需求,我们在此建造了一个能够模拟韩国核电站中可能出现的恶劣 DBE 条件的专门设施。通过详尽的研究,为压水反应堆开发了目标温度和压力曲线,并设计了过热蒸汽喷射技术,以实现快速的温度和压力变化。本研究有助于提高国内 EQ 测试能力,在 30 秒内达到 230 °C 和 700 kPa。
Enhancing equipment qualification testing facility for nuclear power plants: Achieving rapid temperature and pressure increase during design basis events
The present study focuses on the development of an equipment qualification (EQ) testing facility for Class 1E equipment in nuclear power plants (NPPs), emphasizing the need to ensure safety functions under design basis events (DBEs). The Republic of Korea (ROK) has implemented international safety standards to support large NPP projects, necessitating the development of domestic EQ testing facilities to reduce the dependence on foreign facilities. To address this need, herein, a specialized facility capable of simulating harsh DBE conditions that may occur in NPPs in ROK was constructed. Through exhaustive research, target temperature and pressure profiles were developed for pressurized water reactors, and a superheated steam injection technique was devised for rapid temperature and pressure changes. The present study contributes to the advancement of domestic EQ testing capabilities, achieving up to 230 °C and 700 kPa within 30 s.
