Load Analysis of Hypothetical Ruptures and Optimum Design of H-Type Anti-Whip Restraint Devices for High Energy Pipes Based on Bilinearity Method

In order to deal with the dynamic effects induced by the hypothetical ruptures of the high energy pipes in nuclear power plants,the physical isolation and anti-whip restraint devices should be adopted based on the mechanical analysis during the NPP design.This paper not only introduces the calculation methods of jet forces,jet energy and characteristic lengths of circumferential rupture of high energy pipes based on the optimum mechanic mode,but also presents one new bilinearity method which could be used for the design and verification of the H type anti-whip restraint devices.
