abstract

This paper presents a theoretical and numerical investigation of one of the postulated accidents for Boiling Water Reactors (BWRs), namely, a double-ended guillotine break of recirculation outlet line that leads to a sudden depressurization locally at the recirculation outlet nozzle. The depressurization wave front thus formed will propagate inside the reactor leading to transient loads on the internals. The paper discusses the solution to this wave propagation problem.
