Oak Ridge, Tennessee

Different combinations of stable xenon isotopes have been sealed into each of the fuel elements in fission reactors as tags so that should one of the elements later develop a leak, it could be identified by analyzing the xenon isotope pattern in the reactor s cover gas (4). Historically, the sensitive helium mass spectrometer devices for leak detection were developed as a cmcial part of building the gas-diffusion plant for uranium isotope separation at Oak Ridge, Tennessee (129), and heHum leak detection equipment is stiU an essential tool ia auclear technology (see Diffusion separation methods).

Clinch River Breeder Reactor Project, the first large-scale demonstration breeder reactor is constructed near Oak Ridge, Tennessee. The project died for lack of support, however. 

The successful operation of the reactor and plutonium extraction plant at Oak Ridge, Tennessee led to the availability of first milligram, and then gram, amounts of plutonium starting early in 1944, The availability of milligram amounts of plutonium led to the immediate discovery of the III oxidation state. 

Pu-239 and Pu-242 is in preparation and a third, Pu-239, is planned for the future. All the isotopes are available from the ORNL Isotopes Sales Office, Oak Ridge National Laboratory, P. 0. Box X, Oak Ridge, Tennessee, 37830.
