Country's plan to build new

NPPs.

I&C technologies in new NPP

designs

Khmelnitsky NPP, Units 3

Khmelnitsky NPP, Units 4


Vienna

16

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.

2006-2007 – technical analysis of Units 3,4 was performed by

KIEP (Ukrainian design company).

Khmelnitsky NPP, Units 3,4. History


Vienna

17

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.

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 2008-2010 by

Ukrainian vendor.

Two FPGA-based products for Embalse (Argentina)

will be deliver by Ukrainian vendor in cooperation

with Candu Enegy Inc. in 2013-2014.


Vienna

21

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.


Vienna

22

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.

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-

1000 and VVER-440).

No Common Cause Failure

in modernized RTS.


Vienna

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 2010.

Ukrainian cybersecurity regulations have not been

developed yet.

Cybersecurity regulation adoption is possible only in

cooperation between the above two departments.


Vienna

25

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 2000.

2009-2012: 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.


Vienna

26

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
