Feasibility of Breed/Burn Fuel Cycles in Pebble Bed HTGR Reactors.

Abstract

The feasibility of the breed/burn fuel cycle concept, originally proposed for Pu239/U FBR applications, has been evaluated for use in a U233/Th fueled pebble bed HTGR. Because of its excellent neutron economy, its versatility with respect to fueling strategies and the high fuel burnup achievable as well as the ability to approach continuous fueling operation, the pebble bed HTGR was judged to be the best suited, of reactors currently of commercial interest, for implementation of the breed/burn fuel cycle in a thermal/epithermal system. Successul stand-alone breed/burn operation could not be accomplished in U233/Th pebble bed HTGR systems for the ranges of compositions considered in this analysis: 110 < or = C/HM < or = 450.
