DEVELOPMENT OF THE MARK A SAFETY ROD FOR THE HALLAM NUCLEAR POWER FACILITY
A mechanical safety rod in the control system of the Hallam Nuclear Power Facility is required to rake the reactor subcritical in an emergency arising from unusual operating conditions. A prototype safety rod was designed and fabricated for use in a developmental test program. Critical components, including the scram magnet, control element assembly, and the snubber system were tested; results were compared with performance requirements to establish conformity. The developmentul model of the completed safety rod assembly was then tested. A total of 581 cycles of operation was obtained at ambient air temperature conditions, thus concluding the first phase of the safety rod developmental testing. (auth)
