U.S. president Donald Trump issued a collection of directives in Might aimed toward hastening the event of superior nuclear reactors. The directives, delivered through a set of 4 government orders, set formidable targets, resembling having 10 new large reactors beneath development by 2030, and overhauling the U.S. Nuclear Regulatory Commission (NRC).
One particularly eager provision instructs the U.S. Department of Energy to designate, inside 90 days, a minimum of one web site on DOE-controlled land for the deployment of a sophisticated nuclear reactor—a virtually unattainable deadline that’s arising August 21.
The orders sparked a flurry of debate throughout the nuclear trade and despatched stakeholders scrambling. Specialists weighed the promise of accelerated nuclear deployments in opposition to the potential of dropping regulatory integrity. Whether or not the U.S. authorities, navy, and trade stakeholders can meet the calls for of the directives and timelines is unclear.
As somebody with deep experience in nuclear venture improvement and licensing, I’ve chosen to focus this text on the 90-day site-selection directive—maybe the primary litmus check to see if the Trump administration will execute on its difficult deadlines.
The method for choosing a web site for a brand new nuclear plant within the United States is an arduous and sophisticated course of that blends engineering feasibility, environmental science, security, emergency planning, economics, and public belief, all whereas complying with laws and steering. It’s by no means been executed in 90 days, a minimum of not with regulatory approval.
However there may be a technique for the DOE to satisfy that deadline: Depend on websites which are already deeply ready with present documentation and few unknowns. There are two places in america that come near becoming this class: Idaho National Laboratory and Oak Ridge National Laboratory.
The right way to Choose a Web site for an Superior Nuclear Reactor
To host a business nuclear reactor in america, a web site should first obtain a license from the NRC. To get that license, reactor house owners sometimes take a few years to arrange the applying, 6 to 12 months of which is required to carry out and doc the site-selection course of. The regulator then critiques the applying and performs an environmental influence assertion (EIS)—a course of that traditionally took greater than two years, however is now required to be completed in 18 months, per new directives.
Step one in deciding on a web site is to establish the area of curiosity. Subsequent, unsuitable or problematic elements of that area, resembling these which are liable to earthquakes, flooding, or landslides, are eradicated.
Remaining areas of land within the area are then assessed for technical and environmental suitability. For a small modular reactor (SMR), a sort of superior nuclear reactor, an excellent web site dimension is a few hundred acres (about 80 hectares), whereas a thousand acres (over 400 ha) is good for a big nuclear plant. Reactors additionally want enough cooling water, which generally comes from a close-by ocean, lake, river, or aquafer.
Builders should assess the close by inhabitants and infrastructure, seek for endangered species, and assess wetlands. Enterprise elements are additionally thought-about, resembling distance to interconnection with transmission, value to put in and function cooling, and the quantity of web site grading wanted.
Lastly, candidates assign weighting values to the standards and fee websites in opposition to the assorted parameters. This iterative course of, adopted by additional discipline investigations and narrowing of choices, results in the collection of one most popular web site, with two to 4 others outlined as alternate options. After that, the NRC critiques the applying and proceeds with the environmental influence assertion course of.
DOE’s Looming Web site-Choice Deadline
It’s unclear how far alongside the DOE is in its try and adjust to the chief order’s 90-day problem to choose a web site for a nuclear plant. Assembly the deadline would require inventive considering and decisive motion.
With that in thoughts, the perfect path ahead for the DOE is to give attention to websites which have already undergone Nationwide Environmental Policy Act evaluation and a few NRC licensing. The DOE’s Idaho National Laboratory (INL) in Idaho Falls, and Oak Ridge National Laboratory (ORNL) in Tennessee, each meet these standards.
Close to INL, there are two choices: the location the place NuScale Power and Utah Associated Municipal Power Systems had been pursuing an NRC license for an SMR facility earlier than abandoning the project in November 2023, and the location proposed for the Eagle Rock uranium enrichment facility that obtained a license in 2011 however was not constructed.
INL has hosted 52 reactors since 1949, so it’s probably an appropriate place from an environmental and security perspective. Though each the NuScale and Eagle Rock websites meet the intent of the chief order, neither obtained an environmental influence assertion from the NRC for a brand new nuclear reactor. Additional, the Eagle Rock web site is adjoining to INL, not on its web site.
Maybe the best alternative is the 935-acre (378-ha) parcel of land on a peninsula on the Clinch River in Tennessee, adjoining to ORNL. The positioning is federally owned, presently managed by the Tennessee Valley Authority (TVA) and is the one web site in america that has obtained a inexperienced gentle—an early web site allow from the NRC—for SMRs.
The Clinch River web site was partially developed within the Seventies for the Clinch River Breeder Reactor venture, a liquid-metal quick breeder reactor that was deserted within the early Nineteen Eighties. The NRC in 2019 licensed the location to TVA for the development and operation of two or extra SMRs. This permit permits for as much as 800 megawatts electrical (MWe) of nuclear power and adopted a radical environmental and security evaluation that continues to be legitimate via 2039.

In Might this 12 months, TVA requested a construction permit to construct on that web site an SMR referred to as the BWRX-300, a boiling-water reactor, which might have a capability of 300 MWe. However the web site can accommodate extra SMRs and different superior or microreactor models, which might fulfill the chief order’s goals.
Clinch River Is Ideally suited for New Nuclear
TVA was prescient in its considering: Its acknowledged goals for the Clinch River web site embrace powering mission-critical electrical energy masses for nationwide protection, which aligns with the chief order’s priorities. The truth is, TVA’s 2016 utility assessed underground transmission strains to serve mission-critical masses on ORNL—a design function that makes it much less inclined to intentional damaging acts and pure phenomena resembling tornadoes.
The realm already hosts the DOE’s largest electrical energy person, the Oak Ridge Reservation, which incorporates ORNL and the Y-12 National Security Complex, the place nuclear-weapons elements are manufactured and extremely enriched uranium is saved and processed. Traditionally, the area supported the Ok-25 uranium-enrichment facility, which consumed, till the Nineteen Eighties, greater than 1,000 MWe. In the present day, the strong energy infrastructure constructed to serve Ok-25 stays out there in Oak Ridge, together with redundant 161- and 500-kilovolt transmission strains that transect the Clinch River web site.
East Tennessee can be dwelling to one of many nation’s deepest and most skilled nuclear workforces, with TVA, DOE, the College of Tennessee, and lots of private-sector nuclear firms together with Centrus Energy, Kairos Power, LIS Technologies, Nano Nuclear Energy, Orano, Standard Nuclear, Type One Energy, and X-Energy, plus quite a few smaller suppliers, all calling Oak Ridge dwelling.
TVA has not, to this point, catered to information facilities—one of many Trump administration’s priorities. However on 24 July the DOE named the Oak Ridge Reservation one in all 4 places the place it’s going to invite private-sector companions to develop cutting-edge AI data-center and energy-generation projects. An adjoining advanced-nuclear plant on the Clinch River web site would pair properly.
TVA’s New Nuclear Constraints
This uncommon mixture of attributes merely doesn’t exist elsewhere, and makes the Clinch River web site the best location to attempt to meet the provisions within the government orders. However a number of challenges lie forward.
TVA’s standing as a federally owned company comes with constraints that impede progress. Particularly, a US $30 billion cap on the quantity of debt it will possibly tackle was bestowed upon it via the TVA Act and hasn’t been elevated since 1979. TVA has been accused of moving too slowly within the improvement of superior nuclear and SMRs, and Tennessee senators and the president have referred to as for management change on the energy supplier.
Profitable execution of the directive would require management inside the Trump administration. It can require TVA to hunt inventive options and overcome its constraints. One possibility could be to switch the Clinch River web site and its allow from TVA to the DOE. Or maybe the only answer is for the DOE to contract for energy in a way that permits third-party financing of recent nuclear capability, in order that the debt doesn’t fall on TVA’s steadiness sheet.
Given the urgency, significance, and magnitude of the problem of assembly america’ rising electrical energy wants and to perform the intent of the chief orders, DOE ought to designate each INL and ORNL as places to host new nuclear reactors.
