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.

A germanium crystal has been used to measure the absolute intensity of gamma rays from the decay of 238Pu, 212Pb, 212Bi, and 208Tl in a 1 ½-W SNAP-15A heat source. In practically all cases, agreement with other measurements is excellent. In addition, the amount of 236Pu impurity originally present in the sample can be measured with an accuracy of 4%. It is estimated that the 236Pu content in a fuel sample that is several months old can easily be measured with an accuracy of 10%.
