秦山核电厂是我国自行设计、建造的第一个核电站,燃料组件是其堆芯内的主要部件,3×3考验组件是按秦山核电厂燃料组件的设计要求制成的,唯元件长度缩短以适应在HWRR试验回路中模拟压水堆稳态运行条件进行辐照考验,达到平均燃耗25GWd/ Qinshan Nuclear Power Plant is the first nuclear power station designed and built in China. The fuel components are the main components in the reactor core. The 3 × 3 test components are made according to the design requirements of the fuel components of Qinshan Nuclear Power Plant. The only component length is shortened Adapt to the HWRR test loop simulation of PWR steady-state operating conditions for irradiation test to achieve an average burn-up 25GWd /
