Nuclear Energy Research Journals publish latest research and developments in the field of Nuclear Energy. The Journal of Nuclear Energy Science & Power Generation Technology, a peer reviewed journal publishes latest research, review articles, technical notes, commentary, scientific reports and thesis on Nuclear Energy. The energy released during nuclear fission or fusion, especially when used to generate electricity. Nuclear energy is the energy in the nucleus, or core, of an atom. Atoms are tiny units that make up all matter in the universe. Energy is what holds the nucleus together. There is a huge amount of power in an atoms dense nucleus. In fact, the power that holds the nucleus together is officially called the strong force. Nuclear energy can be used to create electricity, but it must first be released from the atom. In nuclear fission, atoms are split to release the energy.
