发帖数: 11249 | 1 Ames Laboratory is a United States Department of Energy national laboratory
located in Ames, Iowa and affiliated with Iowa State University. This is a
top level national laboratory for new research in various domains concerning
national security and resource management. The Laboratory conducts research
into various areas of national concern, including the synthesis and study
of new materials, energy resources, high-speed computer design, and
environmental cleanup and restoration. It is located on the campus of Iowa
State University.
In 1942, Frank Spedding of Iowa State College, an expert in the chemistry of
rare-earth elements, agreed to set up and direct a chemical research and
development program, since called the Ames Project, to accompany the
Manhattan Project's existing physics program. Its purpose was to produce
high purity uranium from uranium ores. Harley Wilhelm developed new methods
for both reducing and casting uranium metal, making it possible to cast
large ingots of the metal and reduce production costs by as much as
twentyfold. About one-third, or around 2 tons, of the uranium used in the
first self-sustaining nuclear reaction at the University of Chicago was
provided through these procedures, now known as the Ames Process. The Ames
Project produced more than 2 million pounds (1,000 tons) of uranium for the
Manhattan Project until industry took over the process in 1945. |
