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. WebFor a typical mass split in the neutron-induced fission of uranium-235, the complementary fission-product masses of 93 and 141 may be formed following the emission of two neutrons from the initial fragments. The division of charge (i.e., protons) between the fragments represents an important parameter in the fission process. Thus, for the mass ...
