NRC looks to leverage previous approvals for large LWRs
During this time of resurging interest in nuclear power, many conversations have centered on one fundamental problem: Electricity is needed now, but nuclear projects (in recent decades) have taken many years to get permitted and built.
In the past few years, a bevy of new strategies have been pursued to fix this problem. Workforce programs that seek to laterally transition skilled people from other industries, plans to reuse the transmission infrastructure at shuttered coal sites, efforts to restart plants like Palisades or Duane Arnold, new reactor designs that build on the legacy of research done in the early days of atomic power—all of these plans share a common throughline: leveraging work already done instead of starting over from square one to get new plants designed and built.

The thick-target neutron energy spectra of the 9Be(p,n) reaction were measured at several angles for proton-bombarding energies of 3.0, 3.4, 3.7, 4.0, and 5.0 MeV. Time-of-flight techniques were used to determine the neutron energy spectra and to discriminate against background radiation. By using lithium-loaded glass scintillators and low proton pulse rate frequency, the neutron spectra have been determined at energies as low as 70 keV. The detectors were calibrated for efficiency using the neutron spectrum of the Al(d,n) reaction, which was accurately measured using fission chamber detectors.
