Conventional Uranium Mills - NRC.gov

feedwater pumps that circulate the water through the boiler. Nuclear plants have similar circulating water pumps and feedwater pumps. In addition, the nuclear plants have emergency equipment that supports safe operation of the reactor. Both nuclear and fossil plants have large battery banks that provide backup DC power to the plant controls.A nuclear power plant (NPP) has a large number of sensors which monitor temperature, pressure and flow rate of the process fluid. Sensors undergo physical degradation, a process accelerated by harsh environments, which results in their readings deviating from the calibration curve. Some of …A conventional uranium mill is a chemical plant that extracts uranium using the following process: Trucks deliver uranium ore to the mill, where it is crushed into smaller particles before being extracted (or leached). In most cases, sulfuric acid is the leaching agent, but alkaline solutions can also be used to leach the uranium from the ore.
