We believe that is a pathway for this technology. One unique feature about liquid fuel reactors is they have the capability of consuming many different types of nuclear fuel. Some in the private sector today are leading with that characteristic to design a reactor to consume spent nuclear fuel. We have taken a commercial decision not to do that, because we think the most important thing is to bring an industrial reactor to the centre of industry quickly with existing fuel sources, which is low enriched uranium rather than spent nuclear fuel.
