TVA nominees promise to support advanced reactor development
Four nominees to serve on the Tennessee Valley Authority Board of Directors told the Senate Environment and Public Works Committee that they support the build-out of new advanced nuclear reactors to meet the increased energy demand being shouldered by the country’s largest public utility.

The University of Lowell high-resolution time-of-light spectrometer has been used to measure angular distributions and 90-deg excitation functions for neutrons scattered from 238U in the energy range from 0.9 to 3.1 MeV. This study was limited to the elastic and the first two inelastic groups, corresponding to states of 238U at 45 keV (2+) and 148 keV (4+). Angular distributions were measured at primary neutron energies of 1.1, 1.9, 2.5, and 3.1 MeV for the same three neutron groups. Whereas our elastic data are in fair agreement with the evaluation in the ENDF/B-IV file, there is substantial disagreement between our inelastic measurements and the evaluated cross sections.
