IMPROVEMENTS IN AND RELATING TO SAFETY RELEASE MECHANISMS

Patent ·
OSTI ID:4025342
A safety release mechanism for releasing a member from a parent member in response to changes in pressure in a fluid in which the releasable number is immersed is described. The device is particalarly applicable to safety rods for nuclear reactors. The mechanism consists of a push rod attached to the releasable member and operable to trip a latch mechanism joining the releasable member to the parent member and a pressure sensitive device located in the releasable member and forming an enclosed space therein. The pressure sensitive device is responsive to pressure changes between the enclosed space and fluid surrounding the releasable member. The pressure senaltive devices releases or trips the latch mechanism when a predetermined pressure change occurs. There may also be a temperature sensitive device operable on the same principal as the pressure sensitive device. (N.W.R.)
