NRC grants standard design approval for the 77 MWe US460

NuScale Power/US460 / NuScale Power Module

The U.S. Nuclear Regulatory Commission approved NuScale's uprated 77 MWe power module design, a scaled-up version from the earlier 50 MWe design. The 250 MWt (77 MWe) module is scalable to 924 MWe across 12 modules and retains the same fundamental safety case and passive safety features previously approved.

• NRC approved uprated 77 MWe design; earlier 50 MWe design approved in March 2017.
• 250 MWt per module; scalable to 924 MWe in multi-module configurations.
• Uses same fundamental safety case and passive safety features as earlier design.
• Approval supports commercial deployment of NuScale small modular reactors.
