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.

Neutron absorption cross sections for 94Zr and 96Zr were measured by an activation technique. Absolute gamma-ray counting of the radioactive daughters, with a Ge(Li) detector-multichannel analyzer system, yielded disintegration rates which were calibrated in terms of cross section with gold samples. Results, in barns, for 2200 m/sec cross sections and resonance integrals are 94Zr, 0.052 ± 0.003, 0.30 ± 0.03; 96Zr, 0.020 ± 0.003, 5.0 ± 0.4, respectively. The low value of the 96Zr thermal cross section requires that the resonance at 301 eV be p wave.
