Cutting-Edge Simulation Technology Supports Growth in Advanced Nuclear Reactors

DAVIDSON, N.C.--(BUSINESS WIRE)-- Curtiss-Wright today announced that it has delivered and completed installation of the Stage 1 Training Simulator (TSN) at TerraPower’s Natrium site in Kemmerer, Wyoming. The TSN is a full-scope simulator that will replicate plant equipment and simulate system conditions and operations to support operator training and licensing. It is built on Curtiss-Wright’s 3KEYMASTER™ simulation software—a real-time, high-fidelity simulation and analysis platform with an extensive installed base in nuclear, power, and process facilities.

“Curtiss-Wright is pleased to announce the successful development and installation of the Natrium Training Simulator at the Kemmerer site,” said Lynn M. Bamford, Chair and CEO of Curtiss-Wright Corporation. “This is a key milestone in our collaboration with TerraPower that exemplifies our ability to leverage Curtiss-Wright’s advanced technologies, domain expertise, and engineering leadership to meet the needs of next-generation nuclear reactors. As a leading global supplier of nuclear reactor technologies, Curtiss-Wright is well positioned to support the anticipated acceleration in demand for advanced reactors and continued expansion of the U.S. reactor fleet.”

“Building the world’s most advanced reactor demands an equally advanced approach to operator training,” said George Piccard, Vice President Plant Operations at TerraPower. “By working with Curtiss-Wright to deliver the Natrium Training Simulator, we are laying the foundation to scale a qualified nuclear workforce across every future Natrium plant and ensuring our operators are fully prepared long before the plant comes online.”

Under previously awarded contracts, Curtiss-Wright will also be developing the Distributed Control Systems (DCS) and the Reactor Protection System (RPS) for the Natrium plant. The Natrium plant design features a 345-megawatt sodium-cooled fast reactor with a patented molten salt-based energy storage system. The storage technology can boost the system’s output to 500-megawatts of power when needed as it is designed to keep base output steady, ensuring constant reliability, and can quickly ramp up when demand peaks—it is the only advanced reactor design with this unique feature. Kemmerer Unit 1 is expected to be the first utility-scale advanced nuclear power plant.

Curtiss-Wright maintains one of the most comprehensive and diverse portfolios of advanced nuclear power equipment, technology, and services globally to support both operating reactors and new build opportunities. Curtiss-Wright performed the work within its Nuclear Division in the Naval & Power segment.

Key Terms

distributed control systems technical

Distributed control systems are networks of small computers placed around a factory or plant that each manage specific equipment or process steps, while a central interface lets operators watch and adjust the whole operation. Think of it like many local traffic lights coordinated from a control room: if one part fails, the rest can keep running. Investors care because these systems affect a company's production reliability, safety, operating costs, and ability to scale, which in turn influence revenue, maintenance spending and regulatory risk.

reactor protection system technical

A reactor protection system is the set of automatic and manual controls and hardware that detect dangerous reactor conditions and place the nuclear reactor into a safe state (typically by initiating a rapid shutdown, or “scram,” and isolating systems as required). It uses sensors (for parameters such as neutron flux, coolant temperature and pressure, and flow) and redundant, diverse logic channels to trigger actions like inserting control rods, stopping pumps, or starting emergency cooling; its design emphasizes fail-safe behaviour and redundancy so a single fault does not prevent a protective action. The system’s role is narrowly protective—not for routine operation or maintenance—so it intervenes only when preset safety thresholds are reached or when operators command a shutdown.

sodium-cooled fast reactor technical

A sodium-cooled fast reactor is a type of nuclear power reactor that uses liquid sodium as its coolant and operates with a fast neutron spectrum, meaning it does not use a moderator to slow neutrons. Liquid sodium transfers heat from the reactor core at near-atmospheric pressure and allows the reactor to fission and/or breed fuel using higher-energy (fast) neutrons; because sodium is chemically reactive with water and air, these reactors require special piping, heat-exchange systems and safety procedures to isolate the sodium and manage chemical and high-temperature risks.
