Dynamic Load Protection Technology for Nuclear Upender and Its Application
-
摘要: 核燃料倾翻机作为翻转燃料组件的重要构件,其安全可靠性至关重要。通过对倾翻机受力情况进行合理分析,建立载荷与运动位置之间的力学模型;根据模型分析结果,提出动态超载、欠载保护方法,实时监测运动过程中倾翻机的正常载荷范围,有效保证燃料组件受力负荷限制要求。结果表明,力学模型建立合理有效,动态载荷保护可以有效地防止核燃料组件因受过大外力破损带来核泄漏的潜在危险。Abstract: As key parts of nuclear fuel assembly’s transport,the nuclear upender’s reliability is significantly important for nuclear safety.By load analysis and simulation,we establish a new mechanical model between upender’s position and load.It also mentions a new kind of dynamic load protection means by comparing the load values with adjusting overload and under load values according to upender’s position.The experiment results show that the new technology can provide more effective protection to ensure no leakage occurred due to accidental forces applied on it.
