What is a reactor cell?

What is a reactor cell?

• A. The inner region of the reactor core where fuel resides.
• B. A control blade mechanism.
• C. The confinement enclosure around the reactor structure that is designed to limit the release of effluents between the enclosure and its external environment.
• D. The containment building.

Answer: (C)

The main idea is that a reactor cell is the confinement enclosure that surrounds the reactor itself to limit radioactivity release into the rest of the plant and toward the outside environment. It creates an immediate, leak-tight barrier around the reactor and its nearby systems, so any potential effluents are kept inside and typically routed through filtration or venting systems before they can escape further. This is different from the reactor core, which is where the fuel resides, or from the control blade mechanism, which moves the control rods. It’s also distinct from the containment building, which is the larger structure that houses the entire reactor area and provides broader safety containment for the facility.
