Standardized design & kit-of-parts

We embrace key design innovations to enable product-based standardization while accommodating coal fleet and heat source diversity. These include automated design, seismic isolation, ‘kit-of-parts’-based design, standardization of supporting systems across multiple heat source vendors, and a ‘universal adaptor’ heat transfer and storage system. These innovations enable a licence once, build many approach, and complete reusability of the design for each site, each time.


Standardized heat source systems

TerraPraxis is leading a world-class consortium in developing the standardized physical system designs and project delivery tools for coal plant owners to rapidly repower their coal-fired power plants with advanced heat sources, such as small modular reactors, that can be delivered as standardized modules from the manufacturer. These technologies can provide clean, affordable, and reliable electricity to billions of people worldwide while limiting the disruption to communities by sustaining and growing local jobs and community tax revenues associated with existing plants.


Seismically isolated standardized buildings

Seismic variations usually require site-specific design which can be costly. Our partners at the University at Buffalo are global experts on nuclear plant seismic isolation. They have found that separating the reactor building from the building’s foundation via seismic isolation allows for a reusable building design across multiple sites of varying seismic risk. It enables the plant to be designed for a range of seismic conditions and licensed once, allowing for a rapid roll-out.


Commercial-grade supporting buildings

We are designing the plant so that there is a clear demarkation of what needs to be in a safety-grade building and what does not. This enables the use of commercial-grade building systems for the non safety grade systems.


Thermal energy storage and steam generators

Thermal energy storage de-links the new heat island safety case from the existing power island, enabling flexible generation and continued use of the balance of plant. The molten salt storage tanks shown here are part of a standardized but customizable heat transfer and storage system. A range of advanced heat sources can be housed in a standardized building and connected to steam generators by a molten-salt-based thermal transport system. The building-integrated reactor system can be configured for a variety of site layouts, energy, and heat demands. Standardization and reduction in design work enables higher volume manufacturing for all aspects of the plant, and delivers significant cost reductions.


Repurposed or new turbines, generators, and cooling systems

Generators and cooling systems are likely to be reusable. The installed base of coal power plant steam turbines varies. The range of advanced heat sources varies as well. The EVALUATE application makes initial assessments of what combinations of heat sources and existing steam turbines allow for steam turbine reuse.


Reuse of grid connection and transmission

Existing coal plant grid connections are extremely valuable assets. They greatly simplify the deployment of repowered coal plant electric power generation.


Completed repowered plant

TerraPraxis has partnered with Bryden Wood to design a standardized, modular building system, benefitting from the design innovations of seismic isolation and separation of the heat island from the power source. The system is designed with a technology-agnostic approach to accommodate a wide range of advanced heat sources, allowing customers to choose from a wide range of advanced heat sources, including light water reactors (LWRs) that are available today, or advanced fission and fusion heat sources, that are projected to be available in the late 2020s.
