Partner with a leader in advanced nuclear innovation

TerraPower’s suppliers and collaborators provide valuable services, materials and manufactured products, and are important members of our extended team. Since 2008, TerraPower has been bringing together the strengths and experiences of the world’s public and private nuclear energy sectors. To date, TerraPower has engaged more than 80 corporations, universities and government agencies from around the globe.

We will continue to put exemplary emphasis on engaging the diversity of the nuclear supply chain, including small, disadvantaged businesses; women-owned small businesses; veteran-owned small businesses; service-disabled, veteran-owned small businesses; and HUBZone small businesses. We have found that working with a diverse supply chain strengthens our ability to deliver quality projects, enhances the capabilities of the small business community, and fosters a healthy business environment.

Supplier Registration

Please complete the new Supplier Prescreening Form and submit it along with your company’s brochure or other documents that highlight your company’s capabilities to suppliers@terrapower.com. TerraPower will not review incomplete application submissions. TerraPower reviews new suppliers on the last week of the month (submission cutoff is the 23rd of every month). Your information will be reviewed to determine whether your company capabilities are a good fit for future business opportunities. Note: If your company is comprised of different subsidiaries, divisions, or locations, a new entry will need to be submitted for each, if applicable.

Suppliers with favorable prescreening results and found to have capabilities that meet our needs will be contacted by a Contract Administrator (CA) who will provide onboarding instructions on how to register and create a profile in TerraPower’s Supplier Portal (BonFire). Please do not contact the CA directly for review status.

As a result of your registration, you may receive occasional emails notifying your company of future or existing opportunities. To learn more about how TerraPower handles your information, view our privacy policy.

THIRD QUARTER, 2023

Reactor Internals / Core Barrel Structures

“Design for manufacturing” support, fabrication, testing, and delivery of fixed structures including the core restraint system, in-vessel storage, core inlet plenum, assembly receptacles, flat baffle plates and other structures (cylindrical risers and baffles) as well as support and flow piping for reactor coolant pumps.

Sodium System Pump

Design, fabrication, and testing of a unit to pump primary sodium through a processing system. This pump provides safety related primary pressure boundary features.

Pool Handling Machine

Design, fabrication, testing, and delivery of a pool handling machine to move spent fuel within Natrium™’s spent fuel pool. This machine will be like spent fuel handling machines used in spent fuel pools at pressurized water reactors.

Reactor Supports

“Design for manufacturing” support, fabrication, testing and delivery of a Reactor Support Assembly (RSA). The RSA is the connection between the reactor to the reactor building. It is expected to bear the load from the vessels’ weight while being flexible enough to handle seismic activity/thermal expansion during operation. It is a Safety Related component. The reactor supports will be a plate type design.

Reactor Vessel Head

“Design for manufacturing” support, fabrication, testing, and delivery of a Reactor Vessel Head (RVH). The RVH shall structurally support the reactor module and various reactor components. The RVH shall anchor the reactor module to the adjacent building structure. The reactor head will be designed to ASME BPVC Section III, Division 5, subsection HBB. The RVH provides support for the reactor and guard vessels. It is expected the RVH head will require welding of at least several forgings.

Neutron Monitoring System

System integrator is required to supply detectors which monitor neutron flux in a high temperature environment around the core as well as the associated electronics for signal amplification and conditioning.

FOURTH QUARTER, 2023

Reactor Vessels

“Design for manufacturing” support, fabrication, testing, and delivery of two major Class 1 pressure vessels which will be designed to ASME BPVC Section III, Division 5, Subsection HBB/HCB. Construction of these vessels is expected to use primarily rolled plate, with limited forgings exclusive to the bottom head and the top flanges.

Fueling Floor Valve

Support the design process and manufacture of a Fueling Floor Valve. Floor valve is used as a temporary closure and opening device for reactor vessel and other containers during refueling and maintenance operations. The fueling floor valve is used at transfer ports provided in the storage cells and vessels, including reactor vessel, to permit the entrance or exit of material.

In Vessel Transfer Machine Instrumentation & Control

Design, fabrication, testing and delivery of a control system that integrates motor controllers, field sensor data acquisition equipment, field control device signal output equipment, a local human machine interface, and a programmable controller.
