DOE, General Matter team up for new fuel mission at Hanford
The Department of Energy's Office of Environmental Management (EM) on Tuesday announced a partnership with California-based nuclear fuel company General Matter for the potential use of the long-idle Fuels and Materials Examination Facility (FMEF) at the Hanford Site in Washington state.
According to the announcement, the DOE and General Matter have signed a lease to explore the FMEF's potential to be used for advanced nuclear fuel cycle technologies and materials, in part to help satisfy the predicted future requirements of artificial intelligence.

A germanium crystal has been used to measure the absolute intensity of gamma rays from the decay of 238Pu, 212Pb, 212Bi, and 208Tl in a 1 ½-W SNAP-15A heat source. In practically all cases, agreement with other measurements is excellent. In addition, the amount of 236Pu impurity originally present in the sample can be measured with an accuracy of 4%. It is estimated that the 236Pu content in a fuel sample that is several months old can easily be measured with an accuracy of 10%.
