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.

In preparation for an in-pile study of tritium release from lithium materials, a sweep gas and radioassay system was tested in Penn State's TRIGA reactor during both steady state and pulsed operation. Sweep gas helium, containing propane, carries tracer level tritium generated in a lithium oxalate powder to a flow-through ionization chamber for radioassay. High tritium sensitivity, the absence of tritium plateout and hysteresis, and good radiological control were demonstrated, encouraging adoption of this approach in our materials study.
