5/19/2018 NuScale Power - Safety and Security Attachment 2 Why SMR? Our Technology NuScale SMR Benefits About Us Safety Features of the NuScale Design In designing the NuScale Power ModuleTM and power plant, NuScale has achieved a NuScale has achieved a paradigm shift in the level of safety of a breakthrough in the safety nuclear power plant facility. It is a revolutionary solution to one of a nuclear power plant, of the biggest technical challenges for the current fleet of using simple passive nuclear energy facilities. systems to provide stable long-term, nuclear core NuScale's innovative and comprehensive safety features are cooling under all conditions, incorporated to provide stable long-term nuclear core cooling including severe accidents.
under all conditions, including severe accidents. These safety features include:

High-pressure containment vessel, redundant passive decay heat removal, and containment heat removal systems.
The integrated design of the NuScale Power Module, Protection Against Extreme Events encompassing the reactor, steam generators, and pressurizer, and its use of natural circulation eliminates the need for large primary piping and reactor coolant pumps.
A small nuclear fuel inventory, since each 50 MWe (gross) NuScale Power Module houses approximately 5% of the nuclear fuel of a conventional 1,000 MWe nuclear reactor.
Containment vessel submerged in an ultimate heat sink for core cooling in a below grade reactor pool structure housed in a Seismic Category 1 reactor building.
