Reactivity control of fast-spectrum reactors by reversible hydriding of

Reactivity control is examinedfor long-lived fast-spectrum nuclear reactors contain- ing yttrium hydride moderating zones. Temperature variation of thehydride provides at- tendant reversible changes in the equilibrium concentration of hydrogen which in turn control the reactivity. Storage of released hydrogen in a reservoir ...


Analysis of Advanced Sodium-cooled Fast Reactor Core Designs

Moreover, minor actinides become fissionable in a fast-neutron spectrum, enabling full closure of the fuel cycle and leading to a minimization of long-lived radioactive wastes. The sodium-cooled fast reactor (SFR) is one of the most promising candidates to meet the. Generation IV International Forum (GIF) declared goals.
