Safety in fusion. An inherently safe process (Spanish Edition)

While nuclear fission derives energy from splitting atomic nuclei, nuclear fusion does so by joining them, releasing energy in the process. Though both atomic reactions produce energy by modifying atoms, their fundamental differences have broad implications for safety. The conditions required to start and maintain a fusion reaction make a fission-type accident or nuclear meltdown based on a chain reaction impossible. Nuclear fusion power plants will require out-of-this-world conditions — temperatures exceeding 100 million degrees Celsius to achieve high enough particle density for the reaction to take place. As fusion reactions can only take place under such extreme conditions, a 'runaway' chain reaction is impossible
