The manipulator is a part of the equipment to unload propulsion reactor SFAs stored at the Lepse service ship.
The manipulator performs the following operations in the confined space of the Lepse storage tanks:
- aligning with an SFA top nozzle in the storage tank,
- gripping the SFA by the top nozzle or by the top of the SFA suspension,
- releasing the SFA in the storage tank,
- lifting and holding the SFA.
The manipulator drives enable vertical rotation and movement, horizontal rotation of the jaws, and the jaws closing/opening. A TV camera on the manipulator rod monitors the SFA gripping. The control system remotely controls the operation of the drives. Manual override devices are provided for the electric drives.
A lifting beam and a rotary frame are designed to transport and store the SFA manipulator.
