流体阻断试验是依据ASME标准设计的一种针对核电厂阀门样机的功能鉴定试验,旨在检验阀门在破口事故工况下是否能有效关闭并截断管道中的介质外溢,是保障核设施安全的一项重要试验。在核电设备国产化的驱动下,重视完善核设备质量管理体系显得尤为重要,而核设备样机的功能鉴定试验直接检验设备是否达到了设计要求,在质量管理体系中起着至关重要的作用。基于这一背景中国原子能科学研究院开展了深入 Fluid Blocking Test is a functional qualification test designed for the prototype of a nuclear power plant valve according to the ASME standard. It is designed to test whether the valve can effectively close and cut off the medium overflow in the pipeline under the condition of a breakage accident, so as to ensure the safety of nuclear facilities An important test. Driven by the localization of nuclear power equipment, it is particularly important to attach importance to improving the quality management system of nuclear equipment. The functional qualification test of nuclear equipment prototype directly tests whether the equipment meets the design requirements and plays a crucial role in the quality management system. Based on this background, China Institute of Atomic Energy conducted in-depth
