Pipe whip restraint
WebbIt is concluded that progress in the design of piping systems in compliance with current regulatory requirements for such a postulated event depends primarily on the … Webb1 juli 2011 · In the mid-1980’s JAERI also conducted tests of pipe whip with U-bar whip restraints. The whipping pipes were 4 inch and 6 inch, pressurized at BWR as well as PWR pressures and temperatures. The tests investigated the dynamics of the whipping pipe and the formation of a hinge at the whip restraint.

WebbA nonlinear dynamic Finite Element Analysis (FEA) is then conducted using ANSYS-LS DYNA program in order to simulate the smashing of a whipping pipe against its own restraint. Break locations will be identified, the thrust force will be computed, plastic hinge formation evaluated, stress-strain curve outlined. WebbThe pipe has a straight run of length 2.286 m (90 in), a very stiff elbow, and a cantilever “stick” 482.6 mm (19 in) long. A bursting diaphragm is installed at the end of the “stick” to initiate the blowdown. The restraint is a set of three U-bolts coupled together.
WebbThe current requirement to provide pipe-whip restraints is applied within the plant to all high-energy piping with a potential for damaging structures, systems, and components essential to safe reactor shutdown. This includes primary RCS piping 30 in. and larger as well as smaller piping systems. Webbpipe whip restraints can be based on experimental data or on an analysis which, because of the complexity of the problem, is best carried out using a computer pro- gram. Since …
Webbthe pipe whip restraint and the support of the jet impingement shield in the piping system of the earlier plant are expensive to build and maintain, and lead to a potential degradation of plant safety. The LBB technology is applicable to the main coolant lines, surge lines, and pipes of the shutdown cooling system, the safety injection system.
