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.

Wall recycling and results of ICRH discharge in the HANBIT mirror device are presented. The amount of gas loading due to recycling from the wall and recycling coefficient are estimated quantitatively by the time evolution of the pressures in each region of the HANBIT mirror device during plasma discharges. These measured pressures are compared with a model calculation made in terms of a coupled set of rate equations. Also we introduce a gas recycling model based on atomic and molecular processes. In this model, enhancement of fueling due to the recycling is evaluated on the basis of the calculated probabilities of neutral and ion production by using the rate coefficients of these reactions.
