报告简介:
Nuclear energy is a vital baseload power source, capable of producing massive amounts of energy from atoms, millions of times more than traditional energy sources. It has the potential to address global energy challenges effectively. There are two main types of nuclear reactions: fission and fusion. Nuclear fission uses uranium or plutonium, which react easily with neutrons. The energy released heats water to produce steam, which spins turbines to generate carbon-free electricity.
Nuclear fusion, on the other hand, uses deuterium and tritium as fuels. These fuse to form helium and neutrons, releasing energy. The neutron energy is transferred to blanket materials, which then heat cooling agents like helium or water. However, fusion is still under development due to challenges in sustaining the reaction in plasma. Managing radionuclides, especially tritium, is a key issue in fusion research. This presentation will cover the basics of nuclear fission, fusion, and tritium science.
