Abstract
An intermediate seismic support system (100) comprises substantially square-shaped seismic support base members (102) which are suspendingly supported from rod position indicator coil assemblies (48) so as to peripherally surround control rod drive mechanism latch housings (20) in order to restrain deflections of the control rod drive mechanisms (12) under seismic conditions. In addition to being remotely installed and removed as a result of being mounted upon the RPI assemblies (48), the seismic supports are also remotely adjustable relative to one another through means of radially movable adjustment blocks (126) which are caused to move radially by means of axially movable actuator blocks (130). The latter blocks (130) are controlled by means of vertically extending actuator rods (134). A seismic support ring (150) peripherally surrounds the entire array of seismic supports (102) so as to laterally constrain the seismic supports (102), the support ring (150) adapted to be connected to the control rod drive mechanism cooling shrouds which, in turn, are connected to the nuclear reactor closure head (10).
