"These reactors have been built and operated before. Currently, there are 20 fast neutron reactors operating around the world, and globally, Russia is leading the development of fast reactor technology, the association says. The technology has been around since the 1950s, according to the World Nuclear Association. But fast reactors are also more efficient with the fuel they do use, he said. "A 'fast reactor' operates in a way that does not slow down the neutrons, in comparison to 'thermal reactors' that contain a moderator, water in today's reactors, that slow down the neutrons," Marc Nichol, NEI's senior director of new reactor deployment and the project lead for the 2019 report, told CNBC.īecause fast reactors do not slow down the nuclei after the fission reaction, they are "harder to catch, so you need more fuel" to power a fast reactor, DeWitte said. In nuclear fission, when a larger atom is split into two, the resulting smaller nuclei are "going about 15,000 kilometers per second," DeWitte told CNBC.
