U.S. president Donald Trump issued a set of directives in Could geared toward hastening the event of superior nuclear reactors. The directives, delivered by way of a set of 4 government orders, set formidable targets, akin to having 10 new large reactors beneath building 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, not less than one web site on DOE-controlled land for the deployment of a sophisticated nuclear reactor—an almost unimaginable deadline that’s arising August 21.
The orders sparked a flurry of dialogue throughout the nuclear business and despatched stakeholders scrambling. Consultants weighed the promise of accelerated nuclear deployments in opposition to the potential of shedding regulatory integrity. Whether or not the U.S. authorities, navy, and business stakeholders can meet the calls for of the directives and timelines is unclear.
As somebody with deep experience in nuclear challenge 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 complicated 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 finished in 90 days, not less than not with regulatory approval.
However there could be a technique for the DOE to satisfy that deadline: Depend on websites which might be already deeply ready with current documentation and few unknowns. There are two areas in the USA that come near becoming this class: Idaho National Laboratory and Oak Ridge National Laboratory.
How you can Choose a Website for an Superior Nuclear Reactor
To host a industrial nuclear reactor in the USA, a web site should first obtain a license from the NRC. To get that license, reactor homeowners sometimes take a few years to organize the applying, 6 to 12 months of which is required to carry out and doc the site-selection course of. The regulator then evaluations 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, akin to these which might be vulnerable 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, a super web site measurement is a few hundred acres (about 80 hectares), whereas a thousand acres (over 400 ha) is right 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 components are additionally thought-about, akin to 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 subject investigations and narrowing of choices, results in the choice of one most well-liked web site, with two to 4 others outlined as options. After that, the NRC evaluations the applying and proceeds with the environmental influence assertion course of.
DOE’s Looming Website-Choice Deadline
It’s unclear how far alongside the DOE is in its try and adjust to the manager order’s 90-day problem to select a web site for a nuclear plant. Assembly the deadline would require inventive pondering and decisive motion.
With that in thoughts, the perfect path ahead for the DOE is to deal with 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 positioning the place NuScale Power and Utah Associated Municipal Power Systems have been pursuing an NRC license for an SMR facility earlier than abandoning the project in November 2023, and the positioning proposed for the Eagle Rock uranium enrichment facility that acquired a license in 2011 however was not constructed.
INL has hosted 52 reactors since 1949, so it’s seemingly an appropriate place from an environmental and security perspective. Though each the NuScale and Eagle Rock websites meet the intent of the manager order, neither acquired 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 perfect selection is the 935-acre (378-ha) parcel of land on a peninsula on the Clinch River in Tennessee, adjoining to ORNL. The location is federally owned, at present managed by the Tennessee Valley Authority (TVA) and is the one web site in the USA that has acquired a inexperienced mild—an early web site allow from the NRC—for SMRs.
The Clinch River web site was partially developed within the Nineteen Seventies for the Clinch River Breeder Reactor challenge, a liquid-metal quick breeder reactor that was deserted within the early Eighties. The NRC in 2019 licensed the positioning 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 is still legitimate by way of 2039.

In Could 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 items, which might fulfill the manager order’s aims.
Clinch River Is Perfect for New Nuclear
TVA was prescient in its pondering: Its acknowledged aims for the Clinch River web site embody powering mission-critical electrical energy hundreds for nationwide protection, which aligns with the manager order’s priorities. The truth is, TVA’s 2016 utility assessed underground transmission strains to serve mission-critical hundreds on ORNL—a design characteristic that makes it much less inclined to intentional damaging acts and pure phenomena akin to tornadoes.
The realm already hosts the DOE’s largest electrical energy consumer, the Oak Ridge Reservation, which incorporates ORNL and the Y-12 National Security Complex, the place nuclear-weapons parts are manufactured and extremely enriched uranium is saved and processed. Traditionally, the area supported the Okay-25 uranium-enrichment facility, which consumed, till the Eighties, greater than 1,000 MWe. Right now, the strong energy infrastructure constructed to serve Okay-25 stays accessible in Oak Ridge, together with redundant 161- and 500-kilovolt transmission strains that transect the Clinch River web site.
East Tennessee can be house 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 house.
TVA has not, so far, catered to information facilities—one of many Trump administration’s priorities. However on 24 July the DOE named the Oak Ridge Reservation one in every of 4 areas the place it would 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 perfect 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 might tackle was bestowed upon it by way of 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’s going to require TVA to hunt inventive options and overcome its constraints. One choice can be to switch the Clinch River web site and its allow from TVA to the DOE. Or maybe the only resolution is for the DOE to contract for energy in a way that permits third-party financing of latest 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 the USA’ rising electrical energy wants and to perform the intent of the manager orders, DOE ought to designate each INL and ORNL as areas to host new nuclear reactors.
