Physics and Design Studies for a Small Breed-and-Burn Reactor

摘要

A compact sodium-cooled B&BR has been investigated from the neutronics points of view. The initial core for the B&BR is chosen to be 60 cm. The radial reflector configuration has also been optimized in order to reduce the excess reactivity of the core. It is found that the hybrid MgO-Pb reflector provides lower excess reactivity and also lower enrichment for the initial core.
