Cost Competitive

A Cost Competitive Nuclear Option for Multiple Applications

We have done more than figure out how to generate energy more efficiently. We’ve employed some of the most powerful minds and effective strategies to design smarter plants, which are smaller, more efficient, scalable, and cost-effective. The NuScale Power Module™, up to 60 MWe (gross) generating capacity, enables utility companies to correctly size their power plants for current needs, then add capacity as necessary.

Since the NuScale Power Module is far less complex than other designs, fabrication and installation on-site are simplified. Off-site fabrication and assembly reduces cost, and components are delivered to the site in ready to install form. As a result, construction occurs in a shorter, more predictable period of time. The workforce required to construct NuScale power plants are measured in the hundreds, not the thousands. Our short 3-year construction schedule provides greater assurance that the plant will achieve operation before unforeseen external events impact the schedule.

The NuScale Power Module has no reactor coolant pumps, no external steam generator vessels, and no large-bore reactor coolant piping. This translates into lower cost to fabricate, install, operate, maintain and decommission, thereby reducing the life-cycle cost to produce energy while lowering operational risk.

In fact, many elements are less expensive, and more efficient, with the NuScale technology. You can expect lower:

  • Total capital costs
  • Financing needs
  • Manufacturing costs
  • Transportation costs
  • Construction costs
  • Operating costs
  • Maintenance costs

A NuScale power plant requires a smaller footprint than a traditional nuclear power plant.

NuScale plants are also adaptable to demand. Additional modules can be added, providing scalability as electricity demand grows. With this approach, financial risks and costs are lower, and schedules are easier to meet.

Construction Costs

Keeping the cost of electricity low to consumers hinges upon two major cost components both of which NuScale’s design is meant to address: 1) Construction (Capital) Cost and 2) Operating Cost.

With the simplicity of NuScale’s design and the economies of small such as factory manufacturing and modular construction techniques, NuScale has engineered an inherently safe and economic solution. By removing much of the construction from the site and placing it in a controlled factory environment both cost and quality are improved over previous designs.

Simpler on-site construction also translates into faster construction times leading to significant cost savings in the financing of facilities.

The estimated construction cost for the first NuScale 684 MWe (net) plant is about $3 billion.

Operating Costs

Smarter energy means keeping an eye out for simplicity. With this in mind, NuScale design results in lower operational costs for a variety of plant systems.

  • Refueling, a significant operational cost, is turned into a routine task instead of a costly every two year evolution.
  • Smaller electric turbine sizes allow for the use of standard work horse turbines requiring little maintenance.
  • Fewer nuclear systems translate into fewer opportunities for equipment to fail and less required maintenance.
  • Operations of multiple module sites lead to centralized maintenance and reduced costs.

Improved reliability cuts down time and increases unit capacity factors to improve utilization of the plant as a capital asset.

Schedule of Construction

Completion of discrete module systems leads to earlier electricity generation as modules can be operating while others are completing their installation.

Reduced site construction time as a result of factory manufacturing and modularization reduces financial risk and lowers financing costs.

Schedule based on 51 months mobilization to mechanical completion; 28.5 months critical path - first safety concrete to mechanical completion.


Innovative self-protecting reactors eliminate any room for mistakes. Fewer safety systems lead to fewer “scrams” (nuclear system shutdowns), increasing reliability and capacity factors.

Frequently planned refueling outages by resident trained crews preclude the need to bring large capacity amounts off line and improve refueling outage time frames leading to more electricity annually flowing to the grid.

Multiple small modular systems reduce the risk of the entire plant being forced off line (single shaft failure) leading to higher capacity factors and improved generation profiles.
