You’ve probably seen those two massive, 400-foot concrete towers rising out of the marshland along the western shore of Lake Erie. If you’re driving between Detroit and Toledo, they’re basically impossible to miss. That’s the Enrico Fermi II NPP, or just "Fermi 2" to the folks living in Monroe County.
Most people see the steam and think "smoke," or they hear the name "Fermi" and immediately think of the 1966 partial meltdown at the first unit. But honestly? Fermi 2 is a completely different beast than its predecessor. It’s a workhorse. While the original Fermi 1 was an experimental "fast breeder" reactor that used liquid sodium, Fermi 2 is a Boiling Water Reactor (BWR). It’s the kind of tech that’s been the backbone of American carbon-free power for decades.
The Christmas Day Disaster You Never Heard About
Whenever people talk about "nuclear accidents," they usually go straight to Chernobyl or Fukushima. But Fermi 2 had its own dramatic moment that almost nobody outside of Michigan remembers.
It was Christmas Day, 1993.
The plant was running at about 93% power. Suddenly, the whole place started shaking. This wasn't a nuclear issue—it was a mechanical one. One of the low-pressure turbines literally tore itself apart. Imagine a massive steel shaft spinning at 1,800 RPM. When the blades broke loose, they became supersonic shrapnel. They ripped through the turbine casing and sliced into cooling pipes.
Over a million gallons of water flooded the basements.
It took more than a year to clean up and fix the non-nuclear side of the plant. No one was hurt, and the reactor itself shut down exactly like it was supposed to, but it remains one of the most expensive "mechanical" failures in the history of U.S. nuclear power. It’s a reminder that even when the "nuclear" part of the plant is safe, the sheer scale of the machinery involved is terrifying.
Why Enrico Fermi II NPP Actually Matters in 2026
We're in an era where everyone is talking about "the grid." Between electric vehicles and AI data centers, we need a massive amount of juice. Fermi 2 provides about 1.1 million kilowatts of electricity. To put that in perspective, that’s roughly 30% of all the nuclear power generated in Michigan.
Without it, the regional grid would look a lot different.
DTE Energy, which operates the site, secured a license renewal back in late 2016. This means the plant is cleared to keep humming along until March 20, 2045. By the time it finally powers down, it will have been operating for nearly 60 years.
Breaking Down the Specs (Simply)
If you’re into the technical side of things, here’s the gist:
- Reactor Type: GE BWR-4 (Boiling Water Reactor)
- Containment: Mark 1 (the "lightbulb" shape you might recognize)
- Cooling: Two natural draft cooling towers (the "big ones")
- Capacity: Roughly 1,170 Megawatts-electric (MWe)
The "Mark 1" containment design has been a point of debate for years, especially after Fukushima. But the NRC (Nuclear Regulatory Commission) has forced plants like Fermi 2 to install hardened vents and extra backup generators. Basically, they've beefed it up to handle "beyond-design-basis" events.
The Wildlife Refuge Nobody Mentions
Nuclear plants need a lot of space. Because you can't build houses right next to the reactor, the land ends up becoming an accidental nature preserve.
At Fermi 2, there are about 600 acres of land that are part of the Detroit River International Wildlife Refuge. It’s weirdly beautiful. You have this massive industrial complex surrounded by American lotus blossoms, bald eagles, and fox snakes. DTE actually works with the U.S. Fish and Wildlife Service to manage the habitat.
It's a strange irony: one of the most high-tech, high-risk structures in the state is also one of the best places for migratory birds to hang out without being disturbed by humans.
Is it safe?
That’s the question everyone asks.
Honestly, the "safety" of a nuclear plant is a moving target. The NRC is constantly on-site. In 2026, they have a whole schedule of baseline security inspections and "fitness-for-duty" checks planned for Fermi.
If you live in Monroe or Wayne County, you've probably heard the sirens. They test them on the last Wednesday of every month at 10 a.m. It’s a routine part of life there. The plant also hands out Potassium Iodide (KI) tablets to residents within a 10-mile radius. Is it because they expect a leak? No. It’s because the law says they have to be ready for the absolute worst-case scenario.
Most people receive less than 1 millirem of radiation a year from the plant’s operation. For context, you get about 300-600 millirems just from existing on Earth, flying in planes, and getting medical X-rays.
What You Should Actually Do Next
If you’re curious about the Enrico Fermi II NPP or nuclear energy in general, don't just rely on headlines. Here are a few concrete steps to take:

- Check the NRC Integrated Inspection Reports: These are public documents. If Fermi 2 has a "tripped" pump or a minor safety violation, it’s listed there. It's the most transparent way to see how the plant is actually performing.
- Request KI Tablets if you're local: If you live within that 10-mile Emergency Planning Zone, make sure you have your Potassium Iodide. It’s free and part of being a responsible neighbor to a nuclear facility.
- Visit the Detroit River International Wildlife Refuge: You can’t walk onto the plant grounds, obviously, but you can visit the nearby refuge areas. It gives you a much better perspective on how the plant sits in the local environment.
- Monitor DTE’s Integrated Resource Plan: This tells you how they plan to replace this power in 2045. Are they going small modular reactors (SMRs)? More wind? Knowing the long-term plan helps you understand the local economy.
Fermi 2 isn't going anywhere for the next two decades. It's a complicated, massive piece of 20th-century engineering that still powers 21st-century lives. Whether you love nuclear or hate it, there's no denying it's a permanent fixture of the Michigan landscape.
