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 Griffin workshop will provide participants with a comprehensive understanding and hands-on training of advanced reactor simulation capabilities in Griffin.
Morning session (8am – 12pm): focuses on prismatic-type high temperature reactor (HTR) applications, including hands-on training in mesh and cross section generation, depletion, and core transport calculations in steady-state and transient conditions.
Afternoon session (1pm – 5pm): focuses on fast reactor (FR) applications, including hands-on training in mesh generation and cross section generation workflow, core transport calculations in steady-state and transient conditions, and fuel management capability.
The registration deadline to ensure software download for the hands-on workshop is Wednesday, April 9th, at midnight.
