Security Built Into Every NuScale Plant

The NuScale Power Module™ and power plant design enhances the intrinsic physical protection and security of the plant through the elegantly simple design, elimination of large break loss of coolant accidents, and full reliance on passive systems to cool the reactors and spent fuel for extended periods without the need for AC power, DC power or additional water following an upset condition. Other security features include:

The low power output of each NuScale Power Module allows for significant design simplification and elimination of many systems susceptible to sabotage, including the reactor coolant loops, reactor coolant pumps, and active safety systems.
A robust, low-profile, seismic Category 1 reactor building encases all reactor modules, the spent fuel pool, and all safety systems, and can withstand aircraft impact.
The small footprint of the NuScale Power Modules plant and the low profile of the reactor building due to below-grade placement of the NuScale Power Modules and spent fuel pool offer a greatly reduced target size relative to traditional LWRs.
Each module is submerged in water, which further reduces post-impact jet fuel fire concerns.
Nuclear core cooling occurs without any external power, which limits plant vulnerability and eliminates loss of off-site power as an issue.
A robust, low-profile, seismic Category 1 reactor building encases all reactor modules, the spent fuel pool, and all safety systems, and can withstand aircraft impact.
