Energiforsk Fredrik Bengtsson FPGA applications at Ringhals 2 | Fredrik Bengtsson |

2 Ringhals – the largest power plant in Sweden
FPGA applications at Ringhals 2 | Fredrik Bengtsson |

3 Ringhals AB Barsebäck Owners: Vattenfall (70,4 %) and E.ON (29,6 %)
Number of reactors in operation: 4 Production capacity: approx. 28 TWh/year Installed power: 3746 MW No. of employees: 1597 Covers approx. 20 per cent of the total demand for electricity in Sweden. Ringhals AB with subsidiary Barsebäck Kraft AB Barsebäck FPGA applications at Ringhals 2 | Fredrik Bengtsson |

4 Background - TWICE project
Objectives Safe and stable operation, high availability in the long term Provide a basis for, at least, a further 20 years operation Improve operator support and maintenance access Comply with the authorities long term safety requirements TWICE The instrumentation and control equipment at the plant has been replaced with new digital technology, including an entirely new control room and simulator Project installed FPGA applications at Ringhals 2 | Fredrik Bengtsson |

5 FPGA application used in TWICE - CIM
Component Interface Module (CIM) is a non software based module that provides the interface between the Safety System and the plant components that it controls. The CIM is also compatible for use in the non Category A, Safety Related System control systems. As used in the Safety System, the CIM receives and coordinates commands from as many as four sources to control Category A components FPGA applications at Ringhals 2 | Fredrik Bengtsson |

6 FPGA application used in TWICE - CIM
A CIM consists of one base with backplane, one communications module, and two priority logic/feedback modules. FPGA applications at Ringhals 2 | Fredrik Bengtsson |

Priority Logic/ Feedback Module A Priority Logic Card A Feedback Card A Communi- cation Module Priority Logic/ Feedback Module B Priority Logic Card B Feedback Card B The FPGA based IO serial controller (IOSC) controls the direction of the transceivers, processes the communication protocol, and creates a parallel bus between the communication module and the priority logic/feedback modules.

9 CIM Block Diagram CIM Priority Logic Card A Feedback Card A
Priority Logic/ Feedback Module A Priority Logic Card A Feedback Card A Communi- cation Module The priority logic card performs the logic needed to control and communicate with one plant component. Primarily this logic is implemented in FPGA, which has a capacity of approximately 16,000 gates available to implement the logic functions. Twenty four application jumpers connect to the FPGA. The configuration of the jumpers makes the priority logic card perform as an E1, E2, E3, E4 component control circuit. A second FPGA interfaces with a serial EEPROM used to store the CIM electronic ID.

10 Experiences The CIM modules was installed during TWICE project 287 CIM modules are used in Safety System and 367 modules are installed in Safety Related System No problem that could be related to FPGA RAB has experienced some problems with the CIM modules but this is related to the power supply of the module. RAB is monitoring and collecting data for further decision. FPGA applications at Ringhals 2 | Fredrik Bengtsson |
