How is reactor coolant chemistry managed and why?

Reactor coolant chemistry is carefully managed to prevent corrosion, minimize the buildup of radioactive contaminants, and ensure the safe and efficient operation of the reactor. The coolant, typically water, is in direct contact with the reactor core and other components, making it susceptible to corrosion and the transport of radioactive materials. In Pressurized Water Reactors (PWRs), the coolant chemistry is typically managed by adding lithium hydroxide (LiOH) to control the pH and hydrogen to suppress the formation of oxidizing radicals....
