Fissile Material
In 1946 the public first became informed of U-233 bred from thorium as "a third available source of nuclear energy and atom bombs" (in addition to U-235 and Pu-239), following a United Nations report and a speech by Glenn T. Seaborg.
The United States produced, over the course of the Cold War, approximately 2 metric tons of uranium-233, in varying levels of chemical and isotopic purity. These were produced at the Hanford Site and Savannah River Site in reactors that were designed for the production of plutonium-239. Historical production costs, estimated from the costs of plutonium production, were $2-4 million / kg. There are few reactors remaining in the world with significant capabilities to produce more uranium-233.

Famous quotes containing the word material:
“It is difficult to generalize why so many Latino/as moved toward conservative ... views.... for many, I believe it is basically a matter of desiring material acquisitions. It is difficult to maintain a collective ideology in a society where possessions and power-status equal self-worth.”
—Ana Castillo (b. 1953)
