Here is the relevant patent- http://www.wipo.int/pctdb/en/wo.jsp?IA=WO2004025666&DISPLAY=DESC
It is a bit of a disappointment, actually a big disappointment if there is nothing more - as there is apparently no real breakthrough- just typical reactor modality with a self-regulating hydride - and 5% enriched - fuel. Too bad. If there is to be a future for this kind of thing, it will probably be in a Russian or Chinese knock-off used there, not here. Maybe when used in remote tar sand areas of Canada, it can find a home. The US simply cannot make this kind of reactor cheaply enough nor safe enough for a public which demands safety first. ... sigh ... Jones
