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 relationship between higher order variational principles for linear functionals of the solution to an inhomogeneous equation and Padé approximants for the same functional is shown. This leads to a deeper understanding of these higher order principles. Further, it is noted that in certain cases, the Roussopoulos functional can yield divergent results while using the Ritz procedure, shown to be equivalent to forming Padé approximants for the functional of interest, gives a generalized Schwinger normalization independent variational principle that can yield finite and convergent results.
