TVA clears huge hurdle in race to build America's first small nuclear reactor

News ClipKnoxville News Sentinel·Oak Ridge, Roane County, TN·7/2/2026

The U.S. Nuclear Regulatory Commission has approved the Tennessee Valley Authority's plans to build a small modular nuclear reactor in Oak Ridge, Tennessee, deeming it safe and feasible. This decision advances TVA's goal to expand its nuclear portfolio and meet rising electricity demand, partly driven by data center development. The project, designed by GE Vernova Hitachi Nuclear Energy, is expected to add 300 megawatts of power.

The U.S. Nuclear Regulatory Commission (NRC) has significantly advanced the Tennessee Valley Authority's (TVA) plans to construct a cutting-edge small modular nuclear reactor (SMR) in Oak Ridge, Tennessee. In a recently released final safety evaluation report, the federal agency concluded that TVA's proposed SMR at its Clinch River site in Roane County is both safe and financially viable, recommending the issuance of a construction permit. This marks a crucial step in establishing East Tennessee as a global leader in next-generation nuclear power.

TheThe planned SMR, a boiling light-water reactor designed by GE Vernova Hitachi Nuclear Energy, is projected to add 300 megawatts of electricity to TVA's grid. The utility, which serves seven states, is pursuing this advanced nuclear technology to meet growing electricity demand, particularly from data center development and population expansion. The NRC's report was delivered ahead of schedule, attributed to efficient review processes and consistent engagement with TVA officials, including Vice President of Nuclear Programs Scott Hunnewell.

Despite an estimated cost of $5.4 billion per unit before interest and tax credits, TVA anticipates the SMRs will offer a reliable power source. The utility aims to complete the first reactor by fiscal year 2032 and has already secured $400 million in federal funding for the project. This development underscores the ongoing efforts to bolster energy infrastructure to support burgeoning technological demands.
