  "account": "The Tennessee Valley Authority (TVA) has received federal approval to construct a BWRX-300 small modular reactor at its Clinch River site near Oak Ridge, Tennessee. This marks TVA as the first U.S. utility permitted to build the GE Vernova Hitachi reactor design, representing a growing interest in small reactor technologies to meet the increasing demand for round-the-clock power. The Nuclear Regulatory Commission (NRC) conducted its review in 14 months, four months ahead of schedule, granting TVA the green light to build the 300-megawatt unit. However, a separate operating license will still be required before the reactor can generate electricity.\n\nThe BWRX-300 is based on boiling-water reactor technology, a design utilized in commercial nuclear plants for many years. It is designed to produce 300 megawatts of electricity, approximately one-fourth of the output of the latest large reactors at Georgia's Vogtle plant. The technology aims to simplify the traditional reactor model by using water as a coolant and relying on natural circulation to transport water through the system. It also includes passive safety features that can utilize gravity, pressure, and stored water instead of solely depending on powered equipment.\n\nThe BWRX-300's smaller size and design allow for fewer components, a smaller footprint, and more factory-made parts. This could potentially reduce construction time and make projects more affordable to finance. TVA is assessing the possibility of building up to four BWRX-300 units at Clinch River, though no construction start date or final cost estimate has been disclosed. The BWRX-300's main attraction is its potential to construct multiple units from the same design, which could lead to lower costs through shared procurement, manufacturing, and construction experience.\n\nBlue Energy, a company in Texas, is also pursuing a similar approach by applying for a permit to build BWRX-300 reactors intended to power data centers. These companies are driven by the growing concern over the power demands of AI data centers, which require generation that can operate continuously, regardless of weather conditions. Nuclear power is one of the few low-carbon options that can provide consistent output, although new plants remain costly and slow to build. The industry's focus on reviving nuclear construction is primarily driven by cost, as the Vogtle project's two newest reactors in Georgia, which cost around $35 billion, were completed years behind schedule. The BWRX-300's standardized design and factory production could help address some of the issues that affected the Vogtle project.",
