What are some of the key similarities and differences between the NuScale reactor and a traditional light water reactor?

The NuScale reactor uses the same basic fuel and core configuration as traditional commercial reactors—the core and amount of fuel are just proportionally reduced. The NuScale reactor is about 20 times smaller than a typical commercial reactor, so its components could be centrally manufactured and transported to power plant sites. Also, the SMR’s cooling systems are vastly simplified and require no pumps, power or human intervention to keep people safe during unplanned events or conditions. These inherent safety features also help to significantly reduce the calculated Emergency Planning Zone around the facility in case of a worst case accident.
