As of 30 November 2025, there has been no widely reported, serious nuclear power plant accident in the United States since the Three Mile Island partial meltdown in 1979, which is still cited as the country’s worst commercial nuclear accident (INES Level 5).(en.wikipedia.org) More recent U.S. nuclear issues include a tritium-contaminated water leak at Minnesota’s Monticello plant in 2022, which regulators characterized as minor with no offsite health impact,(en.wikipedia.org) and a variety of low‑level operational events logged in the U.S. Nuclear Regulatory Commission’s event notification reports (e.g., for 2025) that are classified as non‑emergencies and do not involve harmful radioactive fallout affecting surrounding communities.(nrc.gov) Broader coverage of nuclear energy in 2024–2025 focuses on license extensions (e.g., Turkey Point), reactor restarts (e.g., Palisades, Three Mile Island Unit 1), and SMR approvals rather than on any major accident releasing dangerous fallout on nearby (often working‑class) communities.(theguardian.com) Because Sacks’s prediction is explicitly open‑ended ("inevitably" / "at some point in the future"), and no qualifying U.S. accident has occurred since he made it on 18 October 2024, it has not been falsified or confirmed yet. Therefore the correct status is inconclusive (too early to tell) rather than right or wrong.
