Question 1160Deck General70% to pass
Which part of the inert gas system is designed to relieve sudden large overpressures that exceed the capacity of the mechanical P/V valves?
AI Explanation
The correct answer is B) Liquid filled P/V breaker.
The liquid filled P/V breaker is designed to relieve sudden large overpressures that exceed the capacity of the mechanical P/V valves in the inert gas system. It acts as a pressure relief device, allowing excess pressure to be vented safely. The liquid seal within the breaker ruptures when the pressure exceeds a certain limit, relieving the overpressure.
The other options are incorrect because: A) The pressure control valve regulates the pressure, but does not relieve sudden large overpressures. C) The isolation valve is used to shut off the system, not relieve overpressure. D) The deck water seal is part of the vent system, not the overpressure relief system.
