Name of the Project
Natrium reactor demonstration project.

Location
The project is expected to be built at a retiring coal plant in Wyoming, in the US.

Project Owner/s
Terrapower and PacifiCorp.

Project Description
The demonstration plant is intended to validate the design, construction and operational features of the Natrium technology.

The project features a 345 MW sodium-cooled fast reactor with a molten salt-based energy storage system.

The storage technology can boost the system’s output to 500 MW of power when needed, which is equivalent to the energy required to power about 400 000 homes.

The energy storage capability allows for the plant to be seamlessly integrated with renewable resources.

Potential Job Creation
About 2 000 workers will be needed for construction at the project’s peak. Once the plant is operational, about 250 people will support day-to-day activities, including plant security.

Capital Expenditure
Federal funding is provided for the demonstration activity under a cost-shared cooperative agreement; the result of the project will be a commercially owned generating asset.

Planned Start/End Date
The location of the Natrium demonstration plant is expected to be announced by the end of 2021.

Latest Developments
TerraPower has said early construction activities for the natrium reactor will likely begin in 2024.

Field activities to investigate the site's geotechnical properties, including the drilling of more than 100 boreholes to evaluate the underlying soil and rock, have been under way for the past several months and are scheduled to be complete in early July, the company has said.

Key Contracts, Suppliers and Consultants
TerraPower and GE Hitachi (Natrium system); Bechtel, Energy Northwest, Duke Energy (engineering and construction partners).
