Description

The RadICS Platform is a modular platform and includes standardized modules such as logic module, digital and analog input/ output (I/O) modules, each based on the use of FPGA chips as computational engines. Globally, Radiy digital I&C equipment has been installed in over 70 major safety and control systems applications in operating nuclear power plants (NPPs).

The RadICS Platform is a new generation product, designed in 2011, that has achieved IEC 61508:2010 SIL 3 certification in a single channel configuration. In 2019, the U.S. Nuclear Regulatory Commission has approved the RadICS I&C Platform for use in safetyrelated systems in nuclear power plants. The FPGA technology provides for faster response times than microprocessor technology, with response time as fast as 5 milliseconds. The RadICS Platform consists of general-purpose building blocks that can be configured and used to implement project-specific functions and systems. The system size and architecture are scalable and flexible to fit the typical systems arrangements used in operating and new NPP systems.

The fundamental architecture of the RadICS Platform consists of a single instrument chassis containing a logic module, as well as, up to 14 other I/O and fiber-optic communication modules. This single channel configuration is an IEC 61508 SIL 3 capable digital I&C platform configuration intended for nuclear safety applications. In various configurations, a RadICS Platform-based system can be designed and manufactured to meet U.S. Class 1E requirements and support plant and system specific requirements and functions.

The RadICS Platform provides interfaces with field input and output devices (e.g., sensors, transmitters, and actuators) and display interfaces (e.g., indicators, display panels, alarm systems, etc.). Fiber-optic communication modules can be used to expand the I&C system to multiple chassis and/or communicate with external systems and plant computers. Setpoints can be adjusted using the special tuning interface. Plant and diagnostic data collected is transferred to monitoring station using redundant one-way optical communication interface.
