☢️ Nuclear Energy & Disasters
Chernobyl, Fukushima, and the fuel that could save or destroy the planet.
Chernobyl, Fukushima, and the fuel that could save or destroy the planet.
A single uranium pellet the size of your fingertip contains as much energy as 1 ton of coal — yet nuclear power generates zero direct carbon emissions. With climate change accelerating, nuclear's role in the energy mix is fiercely debated. This quiz covers how reactors work, the science behind history's worst nuclear accidents, and the future of fusion power.
Each round presents 10 randomized multiple-choice questions drawn from a pool of 50, so every playthrough is different. You get instant feedback with explanations after each answer, plus a shareable score at the end.
You'll explore nuclear fission and the physics of chain reactions, France's 70% nuclear electricity grid, the full story of Chernobyl's 1986 explosion and its HBO adaptation, Fukushima's 2011 tsunami-triggered meltdowns, Three Mile Island's impact on US nuclear policy, the waste storage dilemma, nuclear submarine technology, ITER's fusion experiment, and Marie Curie's still-radioactive notebooks.
By deaths per unit of energy produced, nuclear power is statistically among the safest energy sources ever studied — safer than coal, oil, gas, and even some renewables when lifecycle deaths are counted. However, when accidents occur they can be catastrophic in scope. Chernobyl and Fukushima caused significant radiation release, though the direct death toll from radiation is far lower than many assume.
On April 26, 1986, operators at Reactor No. 4 of the Chernobyl Nuclear Power Plant in Ukraine (then Soviet Union) were conducting a safety test with emergency cooling disabled. A sudden power surge caused a steam explosion and subsequent fire that blew off the 1,000-ton reactor lid and released 400 times the radiation of the Hiroshima bomb. 31 people died within weeks; an estimated 350,000 were evacuated. Long-term cancer deaths are disputed (4,000–93,000).
Nuclear generates electricity with near-zero direct carbon emissions, providing reliable baseload power that wind and solar cannot consistently deliver. The IPCC and many climate scientists argue it is a necessary part of reaching net-zero targets. Critics point to the unsolved problem of nuclear waste storage (needing secure containment for 10,000+ years), high construction costs ($10B+ per plant), long build times (10–15 years), and proliferation risks.
