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.

Studies have been performed to evaluate the isotopic neutron source 252Cf for neutron radioraphy. By special methods of fine tuning it is possible to obtain neutron radiographs that can be compared with those obtained from a nuclear reactor facility using very low collimation (gadolinium foil converter, medium resolution film, 1:25 collimator ratio). The 252Cf exposure necessary for this quality neutron radiograph is 1 mg for 100 h (or 10 mg for 10 h, etc.). A neutron source, 244Cm-Be, expected to become available as a by-product of the nuclear power program, provides neutron radiographs similar in quality to those from 252Cf.
