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 2009-2010

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 application used in TWICE - CIM

• A CIM consists of one base with backplane, one communications module, and two priority logic/feedback modules.

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.

Feedback Card B

Priority Logic/ Feedback Module B 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.

Experiences

• The CIM modules was installed 2009-2010 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.
