South Africa, the pebble bed modular reactor (PBMR) has been under design and development for approximately ten years. The PBMR is currently under licence review and final design in South Africa, which currently has a start of construction date in 2007, with a commercial operation date in 2010. At the MIT, which began revisiting pebble

Abstract. This report describes a preliminary design study of a Modular Pebble-Bed Reactor System Reforming (MPB-R) Plant. The system uses one pressure vessel for the reactor and a second pressure vessel for the components, i.e., reformer, steam generator and coolant circulator. The two vessels are connected by coaxial pipes in an …
