TerraPower branches out into medical isotopes

TerraPower, the nuclear research venture founded by Bill Gates, is joining with Isotek Systems and the U.S. Department of Energy in a public-private partnership aimed at turning what otherwise would be nuclear waste into radiation doses for cancer treatment.

The partnership matches TerraPower’s demand for radioisotopes with the federal government’s need to dispose of nuclear material that’s been stored for decades at Oak Ridge National Laboratory in Tennessee.

Isotek, a DOE contractor that’s responsible for overseeing Oak Ridge’s inventory of uranium-233, will use the proceeds from the sale of extracted thorium-229 to accelerate the schedule for disposal of the Cold War stockpile. In a news release, the Department of Energy said the deal will save $90 million in taxpayer dollars.

TerraPower will use the thorium that it purchases from Isotek to further medical applications of radioisotope technologies.
