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.

A detailed discussion is given of the effects of energy diffusion and pitch-angle scattering on the slowing-down dynamics of a beam of monoenergetic particles being released with unidirectional velocity. Approximate solutions are given for characteristic averaged quantities like the pitch-angle averaged distribution function and different physically relevant velocity moments. The relation to previous exact investigations is discussed.
