Self-actuated louvers for venting a CEDM cooling system of a nuclear reactor and method of using the same

摘要

An augmented cooling system for a CEDM in a nuclear reactor includes self actuated louvers or flap valve louvers which allow hot air from the head lift rig to vent and cooler ambient air to enter the rig in the event that pressure is lost for the forced cooled air which normally cools the CEDM.
