Abstract
Non reflecting boundary conditions are applied to the truncation boundary o f large domains to restrict the domain to a small region of interest from w hich waves travel only outwards. In this paper, this procedure is used to c alculate the pressure field in the moderator of a pressurized heavy water r eactor after a coolant channel has failed. Non reflecting boundary conditio ns are applied to the moderator boundary while a perfectly reflecting bound ary is assumed for the channels. (C) 1999 Elsevier Science S.A. All rights reserved.
