According to the U.S. Energy Information Administration , nuclear power plants produced 19.6% of the total electricity generated in the U.S. in 2019. Over the last several years, however, there has been a decline in the number of operating nuclear power plants. If conventional nuclear power plants continue to be shuttered, then how will we replace this energy source? Nuclear reactors are, effectively, costly boilers.While the debate about nuclear power is contentious, one thing remains clear: it remains a critical part of our energy infrastructure. The continued development of SMR technologies may be an important and beneficial upgrade to commercial nuclear energy production.
