"We don't often spend a lot of time being excited in the nuclear industry these days, but this is an exciting thing for us," Kelly told the conference. "We're ready to go."
According to some experts, thorium's advantages are most pronounced in alternative reactor designs such as molten salt reactors and pebble bed reactors, rather than in the conventional solid-fuel, water-cooled reactors in use today.
But other thorium enthusiasts believe that the best way to assert thorium into the energy scene - and thus help deliver CO2-free power - is to first put it to use in reactors that already have regulatory approval.
Thor is testing the thorium fuel in a conventional reactor at Halden cooled by "heavy water" - water that contains an isotope of hydrogen called deuterium. (Although Halden is typically described as a "test reactor," it also provides steam to a nearby paper mill).
Thor hopes to show that the thorium MOX can operate safely and efficiently in a conventional design.
PROCESSES WASTE, TOO
"We expect this experiment to yield data that will be used to demonstrate the safe, long term performance of ceramic thorium MOX fuels, and that this information will directly support the approval of commercial irradiation of such fuels," Kelly said.
By including plutonium in the fuel mix, reactors would not only generate power, but they would also eliminate dangerous waste left over from other nuclear operations and thus help address the problem of what to do with that waste. (The uranium community has similar ideas).
Thor will fabricate some of its own thorium MOX in partnership with Norway's Institute for Energy Technology. Britain's National Nuclear Laboratory - owned by the UK's Department of Energy and Climate Change - will also provide some, as will the European Commission's Institute for Transuranium Elements (ITU).
Westinghouse is helping to fund the project, as are other of Thor's industrial partners including Steenkampskraal Thorium Ltd., a South African company that is developing a thorium-fueled pebble bed reactor. Other partners include Finnish utility Fortum and French chemicals company Rhodia.
Although Cranberry, Pa-based Westinghouse does not like to discuss its thorium activities publicly - presumably because it could undermine the company's conventional nuclear business - it has at least a few thorium-connected and alternative nuclear projects in the works.
