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.

Thoria rods and a water moderator are arranged in a simple rectangular geometry in a multilayered configuration to produce 233U by bombardment with 14-MeV neutrons. The 233U production rate is measured by measuring the 312-keV gamma activity associated with 233Pa. Detailed neutronic calculations have been made using the versatile MCNP Monte Carlo code and the BMCCS2 cross-section library. There is very good agreement between the experimental measurements of 233U production and the corresponding calculations.
