nuclear reaction

"They are so dense that when they accrete material on their surface they can undergo runaway nuclear reactions, which we detect as novae."

Nuclear power stations typically need about 3-5% of this enriched uranium to generate a controlled nuclear reaction that releases energy.

SMRs, sometimes called "mini nukes", work on the same principle as large reactors, using a nuclear reaction to generate heat that produces electricity.

The newest nuclear reaction - Sizewell B - came into service some 30 years ago.

Atoms split naturally, but in 1919, Rutherford oversaw the first artificially-induced nuclear reaction in human history at the Victoria University of Manchester's laboratories.
