Which system is designed to prevent the contamination building from exceeding design values?

• A. Ventilation system
• B. Filtration system
• C. Scrubber system
• D. The spray system lowers reactor pressure and temperature

Answer: (D)

Containment pressure control during accident conditions is what this system targets. The containment spray system dumps water into the containment to condense steam and remove heat, which drops both the pressure and the temperature inside. Keeping containment pressure within its design value is crucial to prevent structural stress or failure and to limit potential releases to the environment. While ventilation, filtration, and scrubber systems manage air quality and remove contaminants from exhaust, they don’t directly prevent the containment from over-pressurizing the way spraying water does. So the spray system is the one designed to keep the containment within its design limits by lowering pressure and temperature.
