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 advantages of replacing obsolete analog equipment with modern digital equipment in a pressurized water reactor are presented. Several modifications to the control system are discussed in detail, with anticipated benefits. The process of rejuvenating the protection system of old 900-MW(electric) plants is described, indicating objectives, technology employed, and new system architecture.
