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.

Electron-photon cascade calculations have been carried out for zero-width beams of 1-GeV electrons normally incident on semi-infinite slabs of water and aluminum. The energy deposited as a function of depth and radius is presented and compared with experimental measurements. The overall agreement between the calculated and experimental results is quite good and is adequate for most shielding purposes.
