【摘要】 中国先进研究堆(CARR)采用的燃料组件在国内尚属首次加工与使用。为了保证燃料组件的完整性和安全性,满足堆安全运行的需要,对燃料板和组件的结构稳定性、流致振动、临界流速、热循环、堆内辐照等进行了设计验证试验。结果表明,CARR燃料组件的设计和加工工艺是合理的,谈组件在反应堆实际运行条件下是稳定和安全的。更多还原

【Abstract】 CARR fuel assemblies are manufactured and used for the first time in China.To ensure the integrity and the safety of the fuel assembly under CARR operation conditions,CARR Project Department arranged a series of design validation tests,such as the tests for structure stability,flow-induced- vibration(FIV),critical velocity,heat circulation,in-pile irradiation and etc.The test results indicated the design and manufacture of CARR fuel assembly are reasonable,and the fuel assembly will be stable and safe under CARR operation condition.更多还原
