Breeding of [sup.233]U in the thorium-uranium fuel cycle in VVER reactors using heavy water

A method is proposed for achieving optimal neutron kinetics and efficient isotope transmutation in the [sup.233]U-[sup.232]Th oxide fuel of water-moderated reactors with variable water composition ([D.sub.2]O, [H.sub.2]O) that ensures breeding of the [sup.233]U and [sup.235]U isotopes. The method is...

Description
Summary:A method is proposed for achieving optimal neutron kinetics and efficient isotope transmutation in the [sup.233]U-[sup.232]Th oxide fuel of water-moderated reactors with variable water composition ([D.sub.2]O, [H.sub.2]O) that ensures breeding of the [sup.233]U and [sup.235]U isotopes. The method is comparatively simple to implement.
