ENGLISH ABSTRACT: The feasibility of a closed loop thermosyphon for the Reactor Cavity Cooling System (RCCS) of the Pebble Bed Modular Reactor has been the subject of many research projects. One of the difficulties identified by previous studies is the precise applicability of appropriate heat transfer coefficient correlations available in literature. This article presents the numerical modelling of the current design of the RCCS, incorporating single phase inside-pipe heat transfer coefficient correlations developed by the author. A one-third-height-scale model of the RCCS was designed and manufactured on which twelve experiments, lasting at least 5 hours each, were performed. The experimental results obtained, were used to verify the theoretical model.
