A major step forward for advanced nuclear energy development in the U.S. is drawing strong support from organized labor, with North America’s Building Trades Unions (NABTU) applauding federal approval of a new reactor project in Wyoming.

The U.S. Nuclear Regulatory Commission has granted a construction permit for TerraPower’s Natrium plant in Kemmerer, marking a significant milestone for next-generation nuclear infrastructure and workforce development.
NABTU President Sean McGarvey emphasized the importance of the decision for both national energy security and job creation in the construction sector.
“The historic NRC decision to grant a construction permit for TerraPower’s Natrium plant in Kemmerer, Wyoming, is a massive win for our nation’s energy security and its working people,” McGarvey said. “TerraPower has engaged tirelessly with the committed and thorough staff at the NRC to prioritize safety and efficiency while creating middle-class, family-sustaining careers.”
The project represents one of the first advanced nuclear reactor developments to receive federal approval, signaling renewed momentum in nuclear energy investment as the U.S. seeks reliable, low-carbon power sources.
“Our members who built this nation’s nuclear infrastructure decades ago are eager to get to work constructing the next generation of this baseload energy source using advanced nuclear technology, and we are proud to do so with partners like TerraPower,” McGarvey added.
The Natrium project will be delivered under a Project Labor Agreement, a structure NABTU says ensures high standards for safety, training and workforce quality. The initiative also involves major construction partners, including Bechtel Corporation.
“This action marks a major milestone for America’s energy future and for the skilled craft workforce building it,” McGarvey said. “Securing the nation’s first construction permit for advanced nuclear reactor development under a Project Labor Agreement with major industry leaders like Bechtel Corporation is a tremendous achievement.”
He noted that the partnership between labor groups, contractors and federal regulators demonstrates how innovation can align with workforce expertise to deliver complex infrastructure projects.
“This shows what is possible when innovation is paired with the most highly trained, highly experienced building trades workforce focused on safety, quality, and long-term reliability that strengthens our nation’s energy security,” McGarvey said.
NABTU said its members are ready to support the project through all phases, with a focus on efficiency and execution.
“We look forward to providing the skilled craft necessary to deliver this project on-time and on-budget,” McGarvey said.
The Natrium plant is expected to play a key role in advancing advanced nuclear technology while reinforcing domestic energy capacity and creating long-term construction employment opportunities.
