The Transformational Challenge Reactor
The Transformational Challenge Reactor (TCR) Program was developed to bring to bear additive manufacturing (AM) and artificial intelligence (AI) to deliver enabling technologies for advanced reactors. TCR is now being joined with Advanced Methods for Manufacturing (AMM) and Nuclear Materials Discovery and Qualification Initiative (NMDQi) to address the whole lifecycle of nuclear materials and related technologies.

A Path Forward for Nuclear
Nuclear energy provides nearly 20 percent of America’s electricity supply. But by 2055, all current nuclear reactors based on light water technology will likely retire due to expiring licenses. There are currently no advanced reactors in operation, although multiple plans exist to invest in new reactor designs and actually build new advanced reactors to prepare for the next generation of nuclear.
The goal of the Transformational Challenge Reactor Program was simple: Leverage advances in manufacturing, materials and computation to enable adoption of technologies to facilitate delivery of reliable, low-cost clean nuclear energy for the nation.
The TCR program worked diligently to transfer its technology to the industry almost as fast as it’s being developed and demonstrated. Industry leaders are already using TCR technology to improve and implement their own designs and to provide clean and cost-competitive energy production.
Goals
Change the cost model for advanced nuclear reactors to be competitive with other technologies.
Dramatically reduce deployment timelines for new nuclear technologies.
Integrate digital data for rapid innovation.
Accelerate the adoption of advances in manufacturing, materials, and computational sciences for nuclear energy.
