Anfield Energy to start construction of Utah uranium mine
British Columbia-based Anfield Energy has scheduled a groundbreaking on November 6 at its uranium and vanadium Velvet-Wood mine, located in southeastern Utah’s Lisbon Valley. According to Corey Dias, the company’s CEO, it will be "more than a groundbreaking—it’s a bold declaration of Anfield’s readiness to help fuel the American nuclear renaissance.”

The rate of neutron absorption in several gold and copper samples has been measured in the PCTR for two different configurations of the fuel and moderator. From these rates, and the corresponding cadmium ratios, the ratio of copper to gold absorption rates for thermal neutrons, and therefore the ratio of the thermal-neutron absorption cross section of copper to that of gold, has been determined. For a value of σAU (0.0253 ev) = 98.8 ± 0.3 barns, the result σCu (0.0253 ev) = 3.79 ± 0.04 barns is obtained.
