Reaction Control - University of Michigan

PRVs default to a closed position and open once a (typically automatic) sensor senses an unacceptably high pressure. When a PRV opens, reactor contents flow out of the reactor to either a coustion area or the open air. With fewer high-pressure contents in the reactor, the pressure within the reactor will decrease to within the acceptable limits.
