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.

The (n,α) reaction cross section for 59Ni has been measured at thermal-neutron energies. The experiment utilized dielectric, alpha-particle track detectors and a known thermal-neutron flux. Twelve measurements were made with nickel samples of different thickness and 59Ni enrichment and with track detectors of varying efficiency. The average of all measurements gave the result σ(n,α) (2200 m/sec) = 13.7 ± 1.2 b.
