NuScale’s SMR design clears Phases 2 and 3 of Nuclear Regulatory Commission’s review process

NuScale Power announced that the U.S. Nuclear Regulatory Commission (NRC) has completed the second and third phases of review of the company’s revolutionary small modular reactor design. This development—six weeks ahead of schedule—marks a significant milestone in the company’s timeline to commercialize its technology.

NuScale’s technology is the first and only SMR to undergo design certification review by the NRC; the announcement brings NuScale closer to bringing the country’s first SMR to market, putting the US on a path to beat foreign competitors such as Russia and China in a global SMR race.

The NRC remains on track to complete its review of NuScale’s design by September 2020, and the company’s first customer, Utah Associated Municipal Power Systems, is planning a 12-module SMR plant in Idaho slated for operation by the mid-2020s based on this certified design.

Phase 2 involves publication of the safety evaluation report (SER) with open items, while Phase 3 consists of the Advisory Committee on Reactor Safeguards (ACRS) review of both the staff’s SER with open items and NuScale’s DCA. The ACRS is an independent advisor to the NRC. The entire review is now in Phase 4.

As the company nears deployment of its pioneering SMR in the US, NuScale has already signed MOUs to explore the deployment of its technology in Canada, Jordan, and Romania, and similar agreements are being discussed with various other potential customers.

In anticipation of the initial NuScale plant deployment, the company has also taken steps to build out its supply chain in recent months, signing preliminary agreements with companies that will offer technical expertise and will manufacture various components of the reactor. The most recent of these include Doosan Heavy Industries and Construction and Sargent and Lundy.

The majority investor in NuScale is Fluor Corporation, a global engineering, procurement, and construction company with a 60-year history in commercial nuclear power.



Could these new SMR replace some of Ontario's older CANDUs at a lower price than refurbished CANDUs?


They are only 50 MW / unit.
I bet they wish they could make them 100 MW.
(Might not be quite as safe i the event of a loss of coolant, though).

@mahonj: 60 MW/unit latest version, FYI.


@Nick, Every 20% helps...
I bet they have plans for all sizes, from 60 - 300, once people get comfortable with them.


Bruce Power of Ontario signed a MoU with NuScale last November.


Nuclear energy delivered to Toronto is currently 2 1/2 times the price of clean Hydro/Wind energy delivered to Montreal (and the rest of the Province) without subsidies. The gap may increase and become 3X to 4X when the total cost to rehab the 19 Ontario Hydro CANDUs is added.

Could mass produced SMRs reduce the price gap to zero?
