The US Nuclear Regulatory Commission has approved NuScale Power’s uprated US460 small modular reactor (SMR) design that could now go into service by the end of the decade.

The uprate approval increases the power output per module to 77 MW from NuScale’s previously-approved 50 MW design. US-based NuScale said it remains the only SMR technology company with design approval from the NRC and is on track for deployment by 2030.

“NuScale’s uprated design features the same fundamental safety case and passive safety features previously approved by the NRC with a power uprate and select design changes to support growing capacity needs,” the company said in a statement.
