Examples

A nuclear chain reaction occurs when one single nuclear reaction causes an average of one or more subsequent nuclear reactions, thus leading to the possibility of a self-propagating series of these reactions. Source: Internet

Because nuclear reaction rates strongly depend on temperature (exp(−E/kT)), achieving reasonable power levels in terrestrial fusion reactors requires 10–100 times higher temperatures (compared to stellar interiors): T ≈ 0.1–1.0 GK. Source: Internet

At 18:59 on 13 July 1954, the reactor reached critical mass and sustained Sweden's first nuclear reaction. Source: Internet

During spallation (bombardment with high energy protons), a uranium carbide target is heated to several thousand degrees so that radioactive atoms produced in the nuclear reaction are released. Source: Internet

Classification by type of nuclear reaction Nuclear fission All commercial power reactors are based on nuclear fission. Source: Internet

In engineered nuclear devices, essentially all nuclear fission occurs as a " nuclear reaction " — a bombardment-driven process that results from the collision of two subatomic particles. Source: Internet
