A few sample questions
1. Which was the world's first nuclear power plant to generate electricity for a commercial power grid, opening in 1956?
Answer: Calder Hall, UK
Calder Hall in Sellafield, England, opened on October 17, 1956, and was the world's first full-scale nuclear power plant to deliver electricity to a commercial grid. Obninsk (1954) was the first to generate electricity but on a smaller experimental scale.
2. The Chernobyl disaster of 1986 occurred in which present-day country?
Answer: Ukraine
The Chernobyl disaster occurred on April 26, 1986, at the Chernobyl Nuclear Power Plant in northern Ukraine (then part of the Soviet Union). It remains the worst nuclear power plant accident in history.
3. What type of nuclear reaction is used in commercial nuclear power plants to generate electricity?
Answer: Nuclear fission
Commercial nuclear power plants use nuclear fission, where heavy atomic nuclei (typically uranium-235 or plutonium-239) are split into lighter elements, releasing enormous amounts of energy as heat to generate steam and electricity.
