Which term describes water that flows in and around a reactor?

• A. Electron
• B. Reactor coolant
• C. Plant components
• D. Neutron

Answer: (B)

Water that flows in and around a reactor is called the reactor coolant. Its main role is to remove the heat produced by fission, helping keep the reactor core at a safe temperature. In many reactors the coolant circulates through the core and heat exchangers, and in some designs it can also act as a moderator, but its primary function described here is cooling. The other terms don’t fit because electrons and neutrons are subatomic particles involved in the reactions, not circulating water, and plant components refer to parts of the equipment rather than the flowing fluid.
