Description

Non reflecting boundary conditions are applied to the truncation boundary of large domains to restrict the domain to a small region of interest from which waves travel only outwards. In this paper, this procedure is used to calculate the pressure field in the moderator of a pressurized heavy water reactor after a coolant channel has failed. Non reflecting boundary conditions are applied to the moderator boundary while a perfectly reflecting boundary is assumed for the channels. (orig.)
