Introduction
When people talk about nuclear power, the conversation usually focuses on climate change: nuclear plants don't burn fossil fuels, so they're often pitched as a "clean" solution (Höffken & Ramana, 2024). But there's a part of the story that rarely makes headlines: the waste and risk this technology creates; they don't fall on everyone equally. Clean energy social equity is often overlooked, and they tend to land hardest on Indigenous peoples, low-income communities, and people who had no say in the decision to build these facilities near their homes. This is what researchers call environmental injustice, and with nuclear energy, it shows up at almost every stage (Höffken & Ramana, 2024).
What Is Environmental Injustice?
The idea is simple: environmental harms, such as pollution, toxic waste, and contaminated land, are not spread evenly across society. Historically, they've been dumped in places where the people living nearby have the least political power to fight back. This pattern was first documented in the 1980s, when communities noticed that toxic waste sites were disproportionately located in poorer, minority neighborhoods (Bullard, 1990, 1994). Since then, the same pattern has been observed again and again with energy projects, including nuclear power (Lee & Byrne, 2019).
There's also a second layer to this injustice: it's not just about people alive today. Some nuclear waste stays hazardous for hundreds of thousands of years. That means people who haven't even been born yet will inherit this waste and the burden of managing it, without getting any benefit from the electricity it once produced. Researchers who study this call it "intergenerational injustice" (Taebi et al., 2012; Schlosberg & Collins, 2014). And the harm isn't limited to humans, either; scholars studying areas around Chornobyl and Fukushima have documented lasting effects on plants and animals (Mousseau, 2021; Mousseau & Møller, 2020), which has led some to argue that justice discussions need to move beyond just human concerns (Tschakert et al., 2021).
The Nuclear Chain
To understand where the harm comes from, it helps to walk through how nuclear power actually gets made; it's a long chain, not a single step.
Mining uranium. It starts with digging uranium ore out of the ground. Uranium naturally comes bundled with other radioactive elements, including a radioactive gas called radon (Eisenbud & Gesell, 1997). Much of the world's uranium has historically been mined on lands occupied by Indigenous peoples in the United States, Canada, Australia, and India, among others (Kuletz, 1998; Eichstaedt, 1994; Gilles, 1996; Green, 2016; van Wyck, 2010; Jarding, 2011; Gupta, 2023) ,and the Navajo Nation in the U.S. is one well-documented example of a community that has suffered serious health consequences from mining activity (Brugge et al., 2007; Brugge & Goble, 2002). Researchers have given this pattern names like "nuclear colonialism" (Kuletz, 1998) and "radioactive colonialism" (LaDuke & Churchill, 1985), and describe it as remote, marginalized communities becoming the main bearers of the risk a process some call "peripheralization" (Blowers & Leroy, 1994; Park & Sovacool, 2018).
Processing the ore. Only a small amount of usable uranium exists in each ton of rock, so processing it leaves behind huge piles of leftover waste, called "mill tailings." These tailings still contain toxic metals and radioactive material (Makhijani et al., 1995), and they're often stored in the same communities where the mining happened.
Enrichment. The uranium needs to be concentrated further to fuel a reactor. This step also produces leftover "depleted uranium," a substance that became widely known after it was used in weapons during the Gulf War, raising health concerns for soldiers and civilians alike.
Running the reactor. Once fuel is in a reactor, it produces electricity but also releases small amounts of radioactive gas and liquid into the air and water, including tritium and noble gases like Argon-41 (Makhijani, 2023; Berg, 2004), and it creates "spent fuel," which is extremely radioactive and stays hot and dangerous for a very long time.
Reprocessing (in some countries). Instead of storing spent fuel, some countries chemically separate plutonium to reuse as fuel (International Panel on Fissile Material, 2015). This process creates even more waste streams, which are often released into the atmosphere or water bodies (NRPA, 2002), and raises the risk that the plutonium could be diverted for weapons.
Long-term storage. Eventually, all this waste needs somewhere to go often deep underground, for tens of thousands of years. No country has fully solved this problem yet (Ramana, 2018).
Accidents. On top of all this, nuclear plants carry a standing risk of catastrophic accidents, as seen at Chornobyl and Fukushima, as well as several near-misses (Brown, 2019; Kastchiev et al., 2007; Lochbaum et al., 2014; Smith, 2006). Sociologist Charles Perrow argued that because of how nuclear plants are technically built, it's impossible to predict in advance exactly what kind of accident could occur (Perrow, 1984) and that includes newer, smaller reactor designs, not just large ones (Ramana, 2021; Ramana & Mian, 2014). When accidents do happen, they can contaminate large tracts of land, making them uninhabitable for decades, or even centuries.
Where Policy Falls Short
Lack of Cumulative Impact Assessments: Standard environmental policies evaluate each new industrial permit in isolation. They fail to account for the cumulative burden of multiple polluting facilities concentrated within a small geographic area.
Disenfranchisement in Policymaking: Marginalized communities frequently lack access to legal resources, and their voices are routinely excluded from the bureaucratic processes that approve zoning changes or industrial developments.
Prioritizing Macroeconomics Over Local Equity: Energy and environmental policies are often justified by broad societal benefits such as economic growth or lower energy prices, while ignoring the localized human costs and policy failures that disproportionately affect lower-income communities.
