What the US Needs for Future Nuclear Power Tech to Get Off the Ground

The National Academies call for the US to be smart about new reactor designs:

"The race against climate change is both a marathon and a sprint," declares a new report from the US National Academies of Science. While we need to start decarbonizing immediately with the tech we have now-the sprint-the process will go on for decades, during which technology that's still in development could potentially play a critical role.

The technology at issue in the report is a new generation of nuclear reactors based on different technology; they're smaller and easier to build, and they could potentially use different coolants. The next generation of designs is working to avoid the delays and cost overruns that are crippling attempts to build additional reactors both here and overseas. But their performance in the real world will remain an unknown until next decade at the earliest, placing them squarely in the "marathon" portion of the race.

The new report focuses on what the US should do to ensure that the new generation of designs has a chance to be evaluated on its merits.

Most of the next generation of nuclear power designs fall into the category of what are termed small modular reactors (SMRs). These designs have two emphases: They are modular and could potentially be mass-produced, and they focus on inherent safety. Combined, these factors will theoretically allow for rapid and cheap production of reactors and a far lower footprint for the supporting power plant where the reactors are installed.
