REPORT ON TESTS CARRIED OUT WITH A SHIP MODEL REPRESENTING CONTROL ROD DRIVE SYSTEM
The control rod drive system controls fission action by moving the control rods and the follower rods in the active core of the nuclear reactor in response to signals from other components of the reactor plant. The system comprises 21 mechanisms with associated power supplies and instrumentation. Each control rod has a mechanism capable of raising or lowering the control rod either independently or in pre-selected groups. The mechanism leadscrew is mechanically coupled to the control rod, and they move in and out of the reactor core as an integral unit in response to electrical signals for positioning and fail-safe requirements. This report presents design criteria and principles of operation for the control rod drive system of the N.S. Savannah. A detailed diagram of the general assembly is provided.
