16 Country's plan to build new NPPs. I&C technologies in new NPP designs Khmelnitsky NPP, Units 3 Khmelnitsky NPP, Units 4 16

17 Khmelnitsky NPP, Units 3,4. History Originally there was a plan to build four VVER-1000 units at Khmelnitsky NPP site. Units 3 and 4 building was stopped in 1990 in accordance with Ukrainian Moratorium to build new NPPs. Construction of units was in 1990: Unit 3 75%, Unit 4 28%. June 2005 Government Regulation on preparation to build new units technical analysis of Units 3,4 was performed by KIEP (Ukrainian design company). 17

18 Khmelnitsky NPP, Units 3,4. Current status Reactor choice VVER-1000 (V-392), permits to improve NPP safety and to extend NPP life time for at least 50 years. January 2011 Ukraine with Russia signed an agreement for cooperation to build Units 3 and 4. May 2011 public hearings took place in Khmelnitsky region and in Kyiv. As a result, some upgrades for safety improvement of design will be agreed with reactor designer. September 2012 Ukrainian Law concerning site, design and construction of Units 3 and 4 at Khmelnitsky NPP was approved. Negotiation with Russia is in progress. 18

20 I&C research and development projects. New I&C technologies 20

21 FPGA Technology issues (1) About 50 FPGA-based Applications have been installed at Ukrainian NPPs since 2004 (Reactor Trip Systems, Neutron Flex Monitoring System, Rector Power Control and Limitation Systems, Reactor Control Systems, ESFAS, Reactor and Conventional Island Control Systems of Normal Operation). 6 FPGA-based ESFASs have been commissioned at Kozloduy-5,6 (Bulgaria) during by Ukrainian vendor. Two FPGA-based products for Embalse (Argentina) will be deliver by Ukrainian vendor in cooperation with Candu Enegy Inc. in

22 FPGA Technology issues (2) Operation experience learning. Experience transfer for CANDU and another types of reactors (not only PWR). Improvement of regulations and procedures concerning FPGA-based platforms and applications development, V&V, operation and licensing. Implementation of SIL (IEC 61508:2010) and IEC 62566:2011 based approach to qualification of FPGA-based platforms and applications. Participation in development of IAEA technical document related to application of FPGAs in NPP I&C systems. Learning cybersecurity issues of FPGA-based systems. 22

23 Diversity issues (1) Ukrainian regulations requires to implement diversity for Reactor Trip System. Original VVER-1000 design included two redundant RTS trains with three channels in each train. Original VVER-440 design included one RTS train with three channels. RPC Radiy is the sole national vendor of RTS.

24 Diversity issues (2) A regulatory decision was made to implement the main RTS and the diverse RTS from the same vendor (FPGAs vs FPGAs+CPUs). Since 2004 RTSs have been modernized for 15 Ukrainian NPP units (for both VVER and VVER-440). No Common Cause Failure in modernized RTS. 24

25 Cybersecurity issues State Nuclear Regulatory Inspectorate of Ukraine includes both: Department of safety regulation of nuclear installations (responsibilities for I&C systems safety regulation), Department of security regulation. New Ukrainian safety and security regulations were approved in 2008 and Ukrainian cybersecurity regulations have not been developed yet. Cybersecurity regulation adoption is possible only in cooperation between the above two departments. 25

26 New Ukrainian Regulation for I&C systems important to NPP safety The first edition of Ukrainian Regulatory Requirements to I&C systems important to NPP safety was approved in : the second edition of the above document was developed. 2012: the final version of the second edition of Ukrainian Regulatory Requirements to I&C systems important to NPP safety was supplied for approval. 26

27 Chernobyl issues Shelter-1 has been under different increased risks. State program of Chernobyl NPP decommissioning was approved (January 2010). Regulatory permission for start of Shelter-2 building was signed (April 2013). Shelter-2 building fulfillment is expected in After that demounting of unstable parts of Shelter-1 can be started 27
