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.

Inertial-Electrostatic Confinement (IEC) is an alternative approach to fusion power that potentially offers the ability to burn advanced fuels like D-He3 in a non-Maxwellian, high density core. These aneutronic reactions are ideal for direct energy conversion; since the products energetic ions, they also offer high specific impulse for space propulsion.
The results presented here are the first potential well measurements of an IEC-type device via a collimated proton detector. They indicate that a ~15-kV virtual anode, at least one centimeter in radius, has formed in a spherical device with a cathode potential of 30 kV, and a current of 12 mA. Numerical analysis indicates D+ densities on the order of 109 cm-3, and D+2 densities on the order of 1010 cm-3.
Virtual well formation is very important to IEC devices because they are, in effect, 100% transparent electrodes that can create an electrostatic well to confine energetic ions. A brief description of the theory of IEC is given, followed by a greater description of the results.
