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.

We built a precision radiography system that measures shells for all current ablator materials to an accuracy of 1:104 in optical depth fluctuation and a spatial resolution of 120 m. The data obtained by the precision radiography system for undoped shells was compared with the data taken using the well-known surface measurement technique Spheremapper. Since both techniques yielded the same power spectrum for the same shell, the results of the precision radiography system were verified. When this technique is compared to the Be:Cu NIF shell, there is no significant internal layer fluctuation. To account for the growing measurement demand, a new x-ray system to accommodate measurements in 1 working day was designed.
