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.

The variances of pulse fluctuations of a periodically pulsed fast reactor have been calculated. The characteristic parameters of SORA, the 1-MW pulsed fast reactor, under development by Euratom at Ispra, have been used as input data. As a result, the relative standard deviation was found to be independent of the duration of the power pulse and the pulse shape and inverse proportional to the square root of the operation power.
