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 comparison is made of the experimental neutron capture background from 3 to l0 MeV of two 252Cf neutron sources, one encapsulated in stainless steel and one in Zircaloy-2. The background of the Zircaloy-2 source was significantly lower than for the stainless steel source above 6 MeV because of the absence of the high energy capture gamma peaks due to iron, chromium, and nickel. Below 5 MeV, the californium fission gamma rays are the major source of interference.
