What does TH stand for?

Professor Cywinski is a leading proponent of the development of a new, safer form of nuclear power using thorium instead of uranium.

Thorium reactors are a type of atomic reactor that can extend any perceived uranium shortage indefinately.

Regarding the nuclear energy, he said the present nuclear power capacity, which was around 3,900 MW, is expected to go up to 7,160 MW by 2012 with the completion of nine reactors which were now in progress, adding that there was a need to plan immediately to increase this capacity to 50,000 MW by 2030 through Uranium and Thorium based nuclear reactors.

Thorium was precipitated as insoluble fluoride and dumped in the depository together with other waste.

The heat lost from the Earth's surface - which originates from the core - is balanced by heat generated in the core by the radioactive decay of uranium, thorium and potassium.

On Wednesday, founding family investors in Yates, who represent about a fifth of its shares, attacked the Thorium bid for undervaluing the pub group.

The company's independent directors said the deal with Thorium -a bid vehicle set up by the management and private equity group GI Partners -was the best option considering the group's current prospects.

The emissivity of Tungsten electrodes used for TIG welding can be improved with the addition of small percentages of Thorium (102%).
