Dynamic Load Protection Technology for Nuclear Upender and Its Application

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.
