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

• A. Reactor coolant
• B. Electron
• C. Nuclear fuel
• D. Activated Corrosion Products

Answer: (A)

Water that flows in and around a reactor is called the reactor coolant. Its job is to absorb the heat produced in the reactor core and carry it away, typically through a closed loop to steam generators or a heat rejection system. This term emphasizes the role of the water as the circulating medium dedicated to cooling the reactor, rather than other substances or byproducts. The other options describe something different: an electron is a subatomic particle, nuclear fuel is the material that undergoes fission, and activated corrosion products are radioactive byproducts formed in the coolant due to irradiation.
