WebMay 5, 2024 · In a nuclear reactor, the energy comes from splitting atoms. Each fission creates two radioactive atoms – U-238, for example, might create Cs-137 and Tc-99 plus a few neutrons. Typically these fission fragments are safely contained within the fuel matrix or “rods,” – which means that one of our goals in designing a reactor ought to be ... WebThe resulting fragments, which are now nuclei with different atomic numbers, are known as fission products. Nuclear fission takes place in a nuclear reactor, which is an enclosed vessel containing a set of nuclear fuel rods that are typically made of uranium or plutonium. The fuel rods are surrounded by a moderator, typically water or graphite ... northline transport tracking

WebSep 23, 2024 · Of the 1.0 GW of reactor power, about 0.7 GW of that is dumped as waste heat through the very large radiators required. The second most massive component is the magnetic mirror at the “top” of the reaction chamber. Its purpose is to reflect the fission fragments going the wrong way so they turn around and travel out the exhaust nozzle. WebFission fragments interact strongly with the surrounding atoms or molecules traveling at high speed, causing them to ionize.
