10 FPGA based I&C Systems which are in operation Regulation, Control and Protection System for research reactor Was developed for research reactor VVR-M (Nuclear Research Institute in Kyiv) based on tested and approved equipment for power reactors. Research reactor VVR-M was successfully put into operation in March 2008 after I&C and electrical parts modernization 10

11 RADIY platform The above-mentioned systems are built on the Digital Radiy Platform. Radiy Platform consists of hardware components and software. The hardware includes limited number of cabinets (11) and block modules (16) of different designation. For example: - Protection forming modules, - Input analog and digital signals, - normalizing converter modules, - analog and digital output modules, - actuator control modules. 11

12 RADIY platform 12

13 RADIY platform To provide diversity oriented solutions for control systems we are using FPGA from different vendors (e.g. Altera & Actel). Software (upper level): - reception of technological and diagnostic information, - visualization of information on every control algorithm, - visualization of diagnostic information on the status of functional module components. - registration, archiving, selection and display of information 13

14 RADIY platform The main principles of RADIY platform development: - All control algorithms performed only on FPGAs: - FPGA-applications have clear and well defined structure; - FPGA-applications and schemes of control technological algorithms have direct equivalent; - Simplification of development and verification processes and reduced number of developmental errors; - Ease of integrating, commissioning and licensing digital I&C systems important to safety of NPPs 14

15 RADIY platform The main principles of RADIY platform development (cont.): - Diagnostic functions are separated from information and control functions; - Absence of a direct connection between computing processes; - Software and FPGA-application verification is based on multi-components V-shape life cycle; - Use multi-components distributed data processing structure with heterogenic networks; - Use of maximal possible quantity of own pre-developed hardware and software with positive service history for design of new I&C systems. 15

16 RADIY platform Radiy Platform meets the safety requirements of national regulations of Ukraine for nuclear applications. Ukrainian safety regulations for I&C systems at nuclear applications act in full compliance with requirements of international IEC standards and IAEA recommendations. 16

17 FPGA based I&C Systems technology - Radiy FPGA-based technology makes it possible to perform all the control functions for nuclear installation: regulation, interlock and protection; - This technology is based on the principle that FPGA chip is taken as a part of hardware and electronic FPGA-application is taken as a software part. - All critical functions are realized only in the form of electronic FPGA-application ( the main reason for common cause failure is removed. - Radiy component Platform is the basis for designing control systems which consist of upper and lower level. - all critical functions are realized at the lower level (algorithms of control/regulation, interlock and protection) 17

18 FPGA based I&C Systems technology - One way information flow is organized between levels from lower to upper level (any impact of the upper level on the lower level is excluded) - Software is used only to solve secondary tasks: - signal reception and processing, - information exchange between system components, - diagnostics, - archiving, - providing man-machine interface. Software amount is decreased Software verification expenses are reduced 18

19 FPGA based I&C Systems technology - This technology-based systems have short response time; - The systems response time does not depend on the number of actuated work algorithms (it is provided by parallel simultaneous processing of all system algorithms) - Simplicity and short time required for making changes to working algorithms ( no need to change the hardware - All the upgraded systems in nuclear applications meet safety requirements stipulated by existing rules and regulations 19

20 FPGA based I&C Systems technology The design stages of developing control systems based on FPGA - System Requirements development - Technical specification development (is verified to see the compliance with System Requirements - Design process (hardware, software, technological algorithms projects), verification to see the compliance with Technical Specification - Hardware production, software coding and making electronic FPGA application (testing) - Control system integration, validation and qualification testing 20
