There is a certain irony in the possibility that one of southwestern Indiana’s former coal-fired power stations could someday become home to a nuclear generating facility.
For generations, coal extracted from beneath the region’s farms, forests, and communities helped power American industry. Mining provided livelihoods for thousands of families, supported local businesses, and shaped the identity of towns throughout the Wabash Valley.
Now, on ground once occupied by a coal-fired generating station, another form of energy production is being considered. The electricity that once helped sustain America’s industrial economy could eventually be produced there for an increasingly digital one.
Amazon, American Electric Power (AEP), and nuclear technology developer X-energy recently announced plans in to explore construction of a 960-megawatt nuclear facility at a former power generating station in Sullivan County. The proposal calls for 12 small modular reactors, each capable of generating approximately 80 megawatts of electricity.
According to company projections, the project could support more than 1,000 construction jobs and over 100 permanent positions. It would also help meet growing electricity demand, including that associated with data centers and artificial intelligence.
For a region with deep ties to energy production, the economic possibilities are considerable. The announcement also raises a reasonable question for those who live nearby: What happens if something goes wrong?
The proposed reactors differ significantly from the conventional nuclear plants many Americans associate with accidents at Three Mile Island, Chernobyl, and Fukushima.
X-energy’s Xe-100 reactor uses helium gas rather than water as its primary coolant. Its uranium fuel is enclosed in multiple protective layers within tiny particles known as TRISO fuel, which are embedded in graphite spheres roughly the size of billiard balls.
The design incorporates passive safety features intended to prevent severe overheating, even during certain failures of electrical power or cooling equipment. Rather than depending entirely on pumps and other powered systems, the reactor is designed to allow residual heat to escape through its vessel and surrounding structures.
Researchers working with the U.S. Department of Energy have tested TRISO fuel at temperatures reaching approximately 3,272 degrees Fahrenheit, demonstrating its ability to retain radioactive materials under extreme conditions.
Those results are encouraging, although they do not establish that a serious accident is impossible.
Even after a reactor shuts down, radioactive decay continues to generate heat. If temperatures become sufficiently high, or protective barriers are compromised, radioactive materials could potentially escape. The Xe-100’s design is intended to make such an outcome substantially less likely, but its safety must ultimately be demonstrated through engineering analysis, testing, and regulatory review.
The technology itself is not entirely new. Related high-temperature gas-cooled reactors have operated experimentally or commercially in other countries; however, the specific Xe-100 design proposed for Sullivan County does not yet have an established record of commercial operation.
That distinction is important when considering the potential consequences for surrounding communities.
Traditional large nuclear plants generally maintain emergency planning zones extending approximately 10 miles from their facilities for potential airborne radioactive releases. A broader 50-mile planning area addresses possible contamination of food and water supplies.
Advanced reactor developers have proposed much smaller planning zones, reflecting differences in reactor design and the quantities of radioactive material that could be released during an accident.
X-energy has discussed an emergency planning boundary of approximately 400 meters, or one-quarter mile, for its technology. That figure, however, is not an approved boundary for the proposed Sullivan County facility, nor does it represent an absolute limit on how far radioactive material could travel.
In the event of a release, the affected area would depend on the quantity and type of material involved, wind direction, weather conditions, and other circumstances. Contamination could extend unevenly downwind rather than spreading uniformly around the plant.
Determining the potential consequences for Sullivan, Linton, and other neighboring communities would require site-specific accident studies and atmospheric modeling reviewed by federal regulators.
The proposed facility’s configuration presents another consideration. Although each reactor would be smaller than a conventional nuclear unit, the project would place 12 reactors at one location. Safety evaluations would need to account for events that could affect multiple units simultaneously, including severe weather, flooding, or disruptions to shared infrastructure.
There are also practical questions beyond reactor safety. Water usage, radioactive waste management, emergency response capabilities, environmental monitoring, and the financial responsibilities associated with construction and eventual decommissioning would all warrant examination.
For residents and local officials, these considerations are not necessarily objections to the project. They are part of understanding what any major industrial development could mean for the area over the coming decades.
Nuclear energy offers certain advantages. It can generate substantial amounts of electricity around the clock without the direct carbon dioxide emissions commonly associated with burning fossil fuels. As electricity demand increases, those characteristics have attracted renewed interest from technology companies and utilities.
At the same time, the history of nuclear energy demonstrates why safety questions cannot be dismissed simply because serious accidents are uncommon.
The Sullivan County proposal remains in its early stages. Before construction could proceed, the project would require extensive engineering work, regulatory review, and applicable approvals from the U.S. Nuclear Regulatory Commission.
Those processes will be important not only in determining whether the facility can be built, but also in establishing what protections would exist for the surrounding communities.
There is something fitting about the possibility that southwestern Indiana, having helped fuel the nation’s industrial development for more than a century, could participate in another transformation of American energy production.
The coal miners who worked beneath this region and the engineers who might someday operate nuclear reactors above it would be separated by generations of technological progress. Their work would serve much the same purpose, though: producing the energy upon which the country depends.
Whether the former Breed station becomes part of that future remains uncertain.
For now, the proposal offers both an economic opportunity and an occasion for thoughtful public scrutiny. The technology deserves to be evaluated on its merits, its risks examined through independent analysis, and its potential consequences explained clearly to the people who would live alongside it.
The region’s energy history is already well established. What comes next deserves equal consideration.
