Abstract
1487566 Reactor control COMBUSTION ENG Inc 26 Sept 1974 [27 Sept 1973] 41956/74 Heading G6C Neutron absorber rods 38, e.g. for emergency shut-down are arranged in a laterally spaced array and means affords lateral compaction as they move longitudinally and lateral uncompaction when their support member stops. The array thereby avoids any jamming due to possible distortion of the duct through which they move. As applied to a sodium-cooled fast reactor the control element assembly (10, Figs. 1, 2, neither shown) comprises a drive mechanism (12), a drive extension (14), a latching device (16), absorber assembly 18 and a hexagonal housing 20. The housing is arranged for sodium cooling via its lower end, and assembly 18 is supported from a member 40 by pivoted arms, e.g. 94, the arms being supported by hinges 106, see also Fig. 3 (not shown). The deceleration of the rod assembly is assisted by a dash-pot.
