Control System Design and Implementation

The control system for the Fission lines Hot Cells was designed to be a standalone system incorporating all necessary interlocks and functions to safely manage operations within the Receipt Cell and Hot Cells. The system uses a PLC, which controls all operations, safety interlocking, and event alarming. Key components and features include:

• Main Control Panel: Houses all electrical power distribution and control system equipment.
• Local Control Panels: Mounted at the front of each Hot Cell, including HMIs for system visualisation.
• Safety PLC System: A dual processor solution providing safety and standard control, achieving SIL 2 safety rating.
• Human Machine Interface (HMI): 5 Local HMIs for operator interaction, mounted on the facia of each cell.
• Network Configuration: Two networks for safety I/O island communications and HMI communications.
• Instrumentation: Includes cell pressure monitoring, gamma monitoring, and fire detection systems.

The implementation of the control system for the Fission lines Hot Cells at the CCFE MRF has resulted in a highly secure and efficient environment for the preparation and analysis of irradiated specimens. The system ensures:

• Safety: Robust interlocks and safety protocols, including emergency stops and fire detection, ensure the safety of operators and the integrity of the facility.
• Efficiency: The integrated control system allows for seamless operation and monitoring, reducing downtime and enhancing productivity.
• Scalability: The use of EtherNet/IP technology and modular components ensures that the system can be easily expanded or upgraded to meet future needs.

Overall, the project has successfully delivered a state-of-the-art control system that supports the advanced research objectives of the CCFE MRF.
