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.

Heat of transports Q* of hydrogen isotopes in the α-phase of Zr have been measured in temperature regions from 623K to 673K for H and from 523K to 623K for T by analysing the redistribution process under a thermal gradient. An isotope mass dependence of Q* has not been unequivocally established though a tendency that Q*(H)>Q*(T) has been observed. These data have been discussed on the basis of the biased-jump diffusion model, and a large negative bias effect has been pointed out as characteristics of Q* of hydrogen isotopes in group-IV metals in comparison with the case of group-V metals.
