Which parameter monitors containment pressure?

Which parameter monitors containment pressure?

• A. Containment Pressure
• B. Containment Temperature
• C. Containment Leakage Rate
• D. Containment Vent Position

Answer: (A)

Direct containment pressure is the parameter used to monitor the pressure inside the containment. Pressure sensors continuously measure the containment gas pressure and feed the data to the safety system and operators, showing whether the containment is within its design limits or experiencing pressure changes during an event. Containment temperature relates to heat removal and can influence pressure indirectly, but it is not the measurement used to monitor pressure. Containment leakage rate indicates how much gas is escaping over time, useful for assessing containment integrity, but it is not the direct reading of the current pressure. Containment vent position reflects whether vents are open or closed, a control setting that can affect pressure, rather than a direct measure of the containment pressure itself.
