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.

It has been proposed to surround the target chamber of the Light Ion Fusion Target Development Facility with a water shield. Such a shield would effectively isolate the radioactive chamber from the environment while providing a medium in which to absorb energy imparted to the target chamber walls following the impact of the fireball. Radioactivity calculations will be presented for five different wall materials. If the water surrounding the chamber provides a damping mechanism for the wall vibrations, it also provides a medium through which a pressure pulse can be transmitted to the outer wall of the shield region. It is desirable to minimize the pressure loading upon this structure. An investigation of the effects of a bubble screen upon the propagation of the water pressure wave is presented, along with some possible criteria for the design of a screen.
