What Politicians Get Wrong About Nuclear Energy (And What They're Starting to Get Right)
Decades of bad takes, knee-jerk opposition, and empty promises have cost the world dearly — but something is finally shifting.
Nuclear energy has spent the better part of fifty years as a political football, kicked around by people who understood it poorly and feared it deeply. Politicians on the left treated it like a four-letter word. Politicians on the right ignored it in favor of whatever fossil fuel was polling best in their district. And the result? The United States, the country that invented commercial nuclear power, now generates barely 18 percent of its electricity from it, while fossil fuels remain dominant at roughly 60 percent. That is not a policy outcome. That is a slow-motion accident.
The good news — and there really is some, which is not something you say lightly about energy policy — is that the political picture is changing faster than almost anyone predicted. The question worth asking now is not just what went wrong, but whether the corrections happening today are serious or just good-looking theater.
The fear factory: how politicians learned to run against atoms
The political fear of nuclear energy did not materialize from nothing. It has roots in real events, real anxieties, and a genuinely complicated technology that is hard to explain at a campaign rally. But somewhere between legitimate caution and actual policy, something went badly wrong.
Three Mile Island is Exhibit A. The 1979 partial meltdown in Pennsylvania is, according to the Nuclear Regulatory Commission itself, the worst nuclear accident in American history. It killed zero people. It caused zero documented long-term health impacts in the surrounding population. What it did cause was a media firestorm, a wave of political panic, and — combined with the coincidental release of The China Syndrome just twelve days earlier — a cultural moment that politicians exploited for decades.
What followed was a regulatory response so extreme that it effectively strangled the industry. Adam Stein, director of the Nuclear Energy Innovation Program at the Breakthrough Institute, describes the aftermath bluntly: what was considered in the public interest became “just reducing risk to as low as possible,” producing “a huge volume of regulations that anybody who wanted to build a new reactor had to know.” The problem is that risk minimization at any cost is itself a risk. Every year nuclear plants weren’t built was another year coal plants kept running. Coal kills people. Routinely. At scale.
The political calculation, though, was straightforward and cynical:
Nuclear is scary and invisible
Accidents make front pages; clean daily operation does not
Environmental groups were loudly opposed
Fossil fuel donors were loudly generous
So politicians took the path of least resistance, and the country’s electricity grid paid the price.
The left’s complicated relationship with clean energy ☢️
Here is something that should embarrass progressive politicians when they look at the scoreboard: nuclear power is America’s largest source of clean electricity. Full stop. Not solar. Not wind. Nuclear. It runs at over 90 percent capacity factor, meaning U.S. nuclear plants operate at full power more than 90 percent of the time every year, far outpacing wind and solar, which are weather-dependent by definition.
And yet, for years, many Democratic politicians treated nuclear as a dirty word — sometimes literally bundling it rhetorically with coal and oil in speeches about “dirty energy.” Senator Elizabeth Warren (D-MA) previously vowed not to back the construction of new nuclear plants. California, the self-proclaimed climate leader, still has a nearly 50-year-old ban on new nuclear development, a policy that is difficult to square with the state’s stated climate ambitions.
Part of the blame belongs to environmental organizations that got this badly wrong. As energy developer Ryan Pickering told the Washington Examiner, some groups “have an interest in not dividing their donors” and kept anti-nuclear positions as a fundraising tool. That is what happens when ideology beats data.
The honest accounting looks like this:
54 percent of Americans incorrectly believe nuclear contributes to air pollution, according to the American Climate Perspectives Survey
In reality, nuclear plants emit no greenhouse gases during operation
Concerns about nuclear safety have been declining steadily since 2018
72 percent of Americans now favor nuclear energy, with those who strongly favor it outnumbering strong opponents by 5 to 1
The public got ahead of the politicians on this one. That is embarrassing for a class of people who claim to follow the science. 🔬
The right’s own blind spots 💡
Republicans did not cover themselves in glory either, just in different ways. The conservative political obsession with fossil fuels — driven heavily by donor relationships with oil, gas, and coal industries — meant nuclear was consistently undersupported even when it should have been a natural fit for a party that claims to love energy abundance and American technological dominance.
Trump’s first term paid lip service to nuclear but did relatively little structural reform. The regulatory regime governing the industry remained a labyrinthine holdover from the 1970s, designed around massive light-water reactors and completely unsuited to the new wave of small modular reactor designs that are now the actual future of the sector.
The political right also has a habit of using nuclear as a rhetorical cudgel — promising reactors for political effect without reckoning with what it actually takes to build them. Australia’s opposition leader Peter Dutton promised his first reactor by the mid-2030s if his coalition won power. New South Wales chief engineer Hugh Durrant-Whyte called the timeline “unrealistic”, noting that Australia would need “many decades” to develop the regulatory expertise, fuel supply chains, and workforce to operate a reactor. A politician promising nuclear plants like he’s promising a new highway is not nuclear policy. It is nuclear-flavored election strategy.
The pattern is consistent and frustrating:
Promise big things about nuclear for political credit
Do little to fix the regulatory and financing structures that actually block nuclear
Move on when the news cycle does
Leave the industry no further forward than before
What’s actually changing — and why it matters 🚀
Now for the part where things get genuinely interesting. Something has shifted in the political world, and it may actually stick this time.
The ADVANCE Act, signed by President Biden in July 2024, is the clearest evidence. The bill passed the Senate 88-2 and the House 393-13 — numbers that are practically science fiction in the current congressional climate. It reformed Nuclear Regulatory Commission licensing fees for advanced reactors, cutting them roughly in half. It created prizes for first-of-a-kind deployments. It streamlined environmental review. It opened the door to foreign investment in U.S. nuclear projects. It even directed the NRC to develop a licensing path specifically for microreactors.
The Harvard Law Review described it as legislation that “strikes a workable balance between maintaining trust in an independent regulator and addressing a clean energy shortage.” That is a measured take. The unfiltered version is that Congress, for one surprising moment, looked at the evidence and acted on it.
State-level politics are shifting too:
Illinois Governor J.B. Pritzker lifted a long-standing ban on large-scale nuclear construction and plans to bring 2 gigawatts of nuclear power online
New York Governor Kathy Hochul directed the New York Power Authority to add at least 1 gigawatt of new nuclear capacity
Even California, the last major Democratic holdout, is at least keeping its existing plant open
Do you think the AI energy crunch is what it finally took to change political minds on nuclear? The timing is hard to ignore. 📈
SMRs: the technology that changes the political math
Part of why the political conversation is evolving is that the technology itself has evolved. Small modular reactors — nuclear plants under 300 megawatts, designed to be factory-built and modular — address almost every objection that politicians have historically used to avoid nuclear.
Too expensive to build? SMRs are designed for factory fabrication, which the Information Technology and Innovation Foundation argues should drive down costs as the technology scales. Too big for smaller grids or remote areas? SMRs can go where large reactors cannot — off-grid, close to industrial sites, on military bases. Too slow to build? The Chinese ACP100, one of the only commercially operating SMRs in the world, went from groundbreaking to grid connection in 58 months.
The Department of Energy has selected 11 companies to participate in a pilot program targeting criticality in at least three test reactors by July 4, 2026. Companies involved include Oklo, TerraPower, Westinghouse, and Kairos Power. Big Tech has jumped in too: Microsoft, Google, and Amazon have all committed to nuclear-backed power purchase agreements, partly because they need the reliable baseload power that intermittent renewables cannot guarantee.
What SMRs do for the political conversation is just as important as what they do for the grid:
Smaller price tags make it easier to secure project financing without decades-long political debates
Factory production means construction jobs spread across manufacturing states, not just the reactor site
Modular deployment lets politicians promise a smaller, faster, more credible first step
Advanced passive safety features in many designs make the Chernobyl comparison even weaker than it already was
Now here is the real question worth sitting with: if SMRs can deliver on even half their promise, which political party will claim credit for it — and which one will have earned it?
The accountability gap: promises vs. pipelines
Being honest about the progress means being honest about what is still broken. The Trump administration’s executive orders in early 2025 directed the NRC to speed up approvals and rewrite safety rules — goals that many nuclear advocates share, in principle. But ProPublica reported that the rollout has been messy, with NRC staff afraid to voice dissenting opinions, career officials leaving in waves, and lawyers withdrawing from licensing proceedings citing “limited resources.” That is not a nuclear renaissance. That is turbulence that could delay the projects it claims to accelerate.
The Vogtle nuclear plant in Georgia — the only new large reactors built in the U.S. in recent years — came online seven years late and $17 billion over budget against an original estimate of $14 billion. Katy Huff, who ran the DOE’s Office of Nuclear Energy under Biden, told WBUR that to meet net-zero goals by 2050, the country needs nuclear growth “rivaling the fastest rate we’ve ever produced new nuclear power plants.” That is a steep ask from a standing start.
What good nuclear policy actually requires, regardless of which party is delivering it:
Stable, long-term regulatory frameworks that don’t change with each election
Off-fee funding for the NRC so it’s not dependent on industry licensing fees
Public investment in fuel supply chains, especially high-assay low-enriched uranium
Honest timelines — not reactor promises designed to win a news cycle and forgotten by the next one
Nuclear energy is not automatically the answer to every grid problem. It is a serious tool that requires serious stewardship. The politicians who get that are starting to act like it. The ones who don’t are still performing. The difference matters enormously — and the next decade will sort them into two very clear groups.
What would it take for you to feel confident that your government is making genuinely smart nuclear policy, rather than just smart nuclear politics?
