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.”

Elastic and one-phonon inelastic scattering cross sections of neutrons in graphite have been calculated for neutron energy less than 2000 k0. For the lattice vibrations in graphite, the model proposed by Krumhansl and Brooks has been used. We have also calculated the mean energy loss per collision and the mean logarithmic energy decrement. Assuming that close to equilibrium the neutron distribution remains Maxwellian, the time variation of the temperature of this distribution has been calculated. The slowing down relaxation time near equilibrium comes out to nearly 170 µsec, which compares well with the experimental value of 185 ± 45 µsec.
