... pressurized water reactors (PWR) is boric acid, which is often referred to as soluble boron ... By varying the concentration of boric acid in the coolant, a process referred to as boration and dilution, the reactivity of the core can be easily varied ... If the boron concentration is increased, the coolant/moderator absorbs more neutrons, adding negative reactivity ...
