Lowering Costs,
Accelerating Innovation


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.
