Reactor Coolant Cleanup Optimization

摘要

Optimization of the reactor coolant cleanup systems in the boiling water reactor (BWR) and pressurized water reactor (PWR) environment is important for controlling the transport of corrosion products (metals and activated metals), fission products, and coolant impurities (soluble and insoluble) throughout the reactor coolant loop, and this optimization can contribute to reducing primary system radiation fields. The removal of radionuclides and corrosion products (predominately isotopes of cobalt and nickel) is just one of many functions (both safety- and non-safety-related) performed by primary reactor coolant cleanup systems. This work evaluates and reports on current efforts at several utilities utilizing advanced resins and cleanup optimization methods. Chemical effluent data is used to evaluate the effectiveness of these technologies. Specific attention is given to those plants or utilities who have conducted parallel testing of media.
