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.

Thoria rods and a water moderator are arranged in a simple rectangular geometry in a multilayered configuration to produce 233U by bombardment with 14-MeV neutrons. The 233U production rate is measured by measuring the 312-keV gamma activity associated with 233Pa. Detailed neutronic calculations have been made using the versatile MCNP Monte Carlo code and the BMCCS2 cross-section library. There is very good agreement between the experimental measurements of 233U production and the corresponding calculations.
