NNSA awards BWXT $1.5B defense fuels contract
The Department of Energy’s National Nuclear Security Administration has awarded BWX Technologies a contract valued at $1.5 billion to build a Domestic Uranium Enrichment Centrifuge Experiment (DUECE) pilot plant in Tennessee in support of the administration’s efforts to build out a domestic supply of unobligated enriched uranium for defense-related nuclear fuel.

The time- and space-dependent temperature distribution within a TRIGA Mark II fuel element has been measured during a series of power excursions. The temperatures were obtained from 14 thermocouples welded to the uranium-zirconium hydride fuel at various radial locations. The experimental temperatures were used to solve the radial time-dependent heat conduction equation for the local heat generation rate (power density) as a function of radius and time during each pulse. Within the accuracy of the measurement, the radial power profile was found to be independent of the fuel temperature.
