The Journal of Nuclear Energy Science & Power Generation Technology is one of the Best Journals in Nuclear Reactors. The Journal of Nuclear Energy Science & Power Generation Technology is a peer reviewed journal and has the most expert and renowned team of editors and reviewers in the field to ensure high quality, solid scholarship and accurate information in all its publications. A nuclear reactor, or power plant, is a series of machines that can control nuclear fission to produce electricity. The fuel that nuclear reactors use to produce nuclear fission is pellets of the element uranium. In a nuclear reactor, atoms of uranium are forced to break apart. As they split, the atoms release tiny particles called fission products. Fission products cause other uranium atoms to split, starting a chain reaction. The energy released from this chain reaction creates heat.
