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.
Nuclear Criticality Safety Division Topical Meeting (NCSD 2022)
Technical Session|Panel
Wednesday, June 15, 2022|8:00–9:45AM PDT|Laguna A
Session Chairs:
Kaushik Banerjee (PNNL)
Justin B. Clarity (PNNL)
Session Organizer:
In this panel session, each panelist will discuss their country-specific approach to post-closure criticality safety in view of the final geological disposal of spent nuclear fuel and high-level radioactive waste. The discussion will include and reflect key topics presently being considered by the new international, waste management organization (WMO)-level collaboration initiative on post-closure criticality safety under the IGD-TP framework (https://igdtp.eu/). Each speaker will give a 10-minute summary with a Q&A afterwards.
