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.
20th International Topical Meeting on Nuclear Reactor Thermal Hydraulics (NURETH-20)
Dr. Lahey is a specialist in two-phase flow and heat transfer and is widely considered to be an expert in nuclear reactor thermal-hydraulics & safety technology. He is the author of many archival papers and books, and is currently the Edward E. Hood Professor Emeritus of Engineering at Rensselaer Polytechnic Institute (RPI). He is an active consultant (technical and expert witness) and is a founding Director of PJM Interconnection LLC, the largest supplier / market operator of wholesale electricity in the country.
