Primary among the changes was the decision to run the reactor at much higher …

Nov 9, 2016 · Nuclear power plants use heat generated in the atomic fission to generate steam and produce electrical power. The fuels for reactors are usually radioactive isotopes of uranium and plutonium. When these materials undergo fission, they break down into smaller elements and release energy and subatomic particles. A nuclear reactor produces and controls the release of energy from splitting the atoms of certain elements. In a nuclear power reactor, the energy released is used as heat to make steam to generate electricity. (In a research reactor the main purpose is to utilise the actual neutrons produced in the core. In most naval reactors, steam drives a ... Nuclear power stations are a major source of energy for many countries around the world.
