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.
Keynotes Session

Session Chair:
Fan-Bill Cheung (PSU)
Dr. Robert (Bob) Salko performs research in the area of computational thermal hydraulics to support modeling and simulation of light water reactors and molten salt reactors. His primary focus has been on development of subchannel and system thermal hydraulics codes, which includes modeling of two-phase flow and heat transfer, coupling with other reactor modeling tools, deployment on high performance computing systems, and implementing quality assurance measures and releasing software for users in the nuclear community. Bob has been working at Oak Ridge National Laboratory for approximately ten years, where he has supported efforts in the US Department of Energy Consortium for Advanced Simulation of Light Water Reactor and Nuclear Energy Advanced Modeling and Simulation programs. Prior to that, Bob obtained his PhD in nuclear engineering from The Pennsylvania State University.
