WebJul 23, 2024 · The fission creates radioactive isotopes of lighter elements such as cesium-137 and strontium-90. These isotopes, called "fission products," account for most of the heat and penetrating radiation in high-level waste. Second, some uranium atoms capture neutrons produced during fission. These atoms form heavier elements such as plutonium.

WebCommon units for heat transfer rate is Btu/hr. Sometimes it is important to determine the heat transfer rate per unit area, or heat flux, which has the symbol \( \dot{Q}'' \). Units for heat flux are Btu/hr-ft 2. The heat flux can be determined by dividing the heat transfer rate by the area through which the heat is being transferred. WebAnd when the fission rate decreases, the control rods pull back. Control rods can form up of elements like Boron, Silver, Indium, and Cadmium. 4. Coolant: Coolant circulates around the reactor core in multiple (usually 2-3) loops. The coolant absorbs the heat from the nuclear fission occurring in the core and transfers it to the turbine.
