About the Texas Nuclear Alliance
TNA is the only industry association in Texas dedicated to the advancement of nuclear technology in the state. Formed in 2022 in the aftermath of Winter Storm Uri, and comprising ofover 70 member entities today, TNA is based on the fundamental premise that if Texas and the world want low-carbon, reliable energy, it can no longer turn its back on nuclear energy. In the 89th Texas Legislature, TNA helped pass four nuclear-dedicated bills, including House Bill 14, a $350 million investment by the state in nuclear energy—the largest of its kind in the U.S—that led to the creation of the Texas Advanced Nuclear Energy Office (TANEO). TNA was formed with a singular mission: to make Texas the Nuclear Capital of the World. Nuclear is clean, safe, reliable, and secure.
