Main Activities and Achievements in the Field of IC Development and Implementation at Russian NPPs

1. Main Activities and Achievements in the Field of I&C Development and Implementation at Russian NPPs Vladimir P. Sivokon Russian Research Center �Kurchatov Institute� (RRC �KI�), Moscow, Russia Phone +7(095) 196 9378, Fax +7(095) 190 5171, E-mail: sivla@dcmm.kiae.ru

2. General and administrative information In spring 2004 the structure of Russian Government has been significantly changed and number of the Ministries was decreased Ministry of Atomic Energy of Russian Federation was reorganized to Federal Agency on Atomic Energy (Rosatom) headed by Mr. A Rumyantsev (former Minister) In spring 2005 Mr. S. Antipov, former director of Kalinin NPP, became a President of Russian Utility �Rosenergoatom� (the only Utility of NPPs in Russia)

3. New NPP Units commissioning and plans of construction (confirmed in 2005) In December 2004 WWER-1000 Unit (Kalinin-3) was started up with the new programmable I&C systems both at low and upper levels of the Unit control Volgodonsk-2 (WWER-1000) start-up is scheduled for 2008 Kalinin-4 (WWER-1000) start-up is scheduled for 2011 Balakovo-5 (WWER-1000) start-up is scheduled for 2011 During last two years the design activities on WWER-1500 are increasing, the new NPP with WWER-1500 supposed to be started up at the Leningrad NPP site

4. Electricity generation in Russia

5. Capacity factor of Russian NPPs

6. Trend of the events at Russian NPPs

7. Current age of Russian NPP Units in Operation (calculated for the mid of 2005):I&C modernisation is executed at many Units

8. Main activities in I&C field: International cooperation IAEA (Review missions on Bushehr NPP APCS design, International DB on NPPs I&C modernization projects, Invitation of the OSART mission to Volgodonsk NPP in October 2005 and other activities) WANO (invitation and participation in peer-review missions at different plants) TACIS (projects on I&C modernization at Balakovo, Kalinin, Novovoronezh and other NPPs, modernization of Leningrad NPP full-scope simulator for HMI research of RBMK MCR) Bilateral cooperation (France, Germany, Norway, South Korea, USA and other countries)

9. Main activities in I&C field:domestic experience Design and qualification of new programmable controllers for implementation in WWER safety systems (VNIIA and Fizpribor, Moscow) Development of philosophy of the I&C design for WWER-1500 and new generation of WWER-1000 Development of VR-based simulation systems for NPPs personnel training and knowledge management Modernisation of I&C at many RBMK and WWER Units Further development of certification system for nuclear equipment, including main I&C systems

10. Main achievements in I&C field Design and commissioning new computerized I&C for Kalinin NPP (Unit-3), implementation of soft control for WWER-1000 for the first time in Russia (separate reports to be presented by Mrs. Dunaev and Bozhenkov, VNIIAES) Qualification of TPTS (manufactured by VNIIA, Moscow) programmable controllers for application in systems important to safety, their commissioning in safety and turbine control systems of Kalinin-3 Design and trial commissioning at Balakovo NPP new programmable controllers (designer and manufacturer is �Fizpribor�, Moscow) for replacement of analogue devices (UKTS) used in WWER safety and other systems. These new means provide functional succession and do not require any significant change of original project documentation on I&C. Number of I&C cabinets can be reduced by about 8 times

11. Example of microcontroller-based board designed by �Fizpribor�

12. Main achievements in I&C field (cont.) Implementation at the nuclear power plants intellectual pressure transmitters (�Metran�, Chelyabinsk) Modernization of I&C systems at many RBMK and WWER Units (for example, Balakovo, Kalinin, Kursk, Novovoronezh, Smolensk, etc.) Extension of functions of the Leningrad NPP full scope simulator (FSS) by development and connection to FSS a VR-based MCR for RBMK HMI enhancement (DS&S, RRC � Kurchatov Institute�)

13. Further development of LNPP refuelling machine VR-Simulator to train maintenance personnel RRC �KI� and IFE (Halden, Norway) developed and implemented Refuelling Machine Simulator (RMS-VR) at Leningrad NPP RMS-VR is on-line connected with RBMK FSS for the operators shift team training and in 2004 it was further enhanced to train the maintenance personnel too

14. Experience of VR-simulator creation at Leningrad NPP was used for development of multimedia training systems for Kalinin NPP Demonstration of 3D-models of equipment Showing internal design details 3D-animation of equipment components Interactive 3D- scenarios of assembling-disassembling processes

15. Problems of current importance relevant to possible international cooperation Identification of new ratio between automated and manual control for the next generation of NPPs (increasing level of automation) Unification of the I&C technical means within each safety class Use of new technologies for I&C and NPP simulators design Comparison and harmonization of Russian and international requirements on design and qualification of I&C systems important to safety, especially programmable ones Human Machine Interface enhancement for new generation of NPPs
