THE BIG PICTURE: Nuclear I&C
Progress in electronics and information technology has created incentives to replace traditional analog instrumentation
and control (I&C) systems in nuclear power plants with digital I&C systems, or systems based on computers and
microprocessors. About 40% of the world's operating reactors have been modernized to include at least some digital
I&C systems, according to the International Atomic Energy Agency. From another perspective, 90% of all digital I&C
installations have been modernization projects at existing reactors; 10% have been at new reactors. POWER looks at
nuclear plants around the world that are leading the digital revolution.

JAPAN
CHINA
In China, Qinshan
Phase III, with two
700-MW(e) CANDU
reactors, and
Tianwan-1 and -2,
with two 1,000MW(e)
VVERs, have
fully digital I&C
systems, including
both the safety and
control systems, and
partly computerized
(hybrid) humansystem
interfaces.
China's hightemperature
gas-cooled
experimental
reactor, the
HTGR-10, also has
fully digital safety
and control I&C
systems, plus a
hybrid humansystem
interface in
its main control
room.
10
In Japan, the first
fully digital I&C
system was
integrated into the
KashiwazakiKariwa-6
advanced
boiling water
reactor (ABWR) in
1996, followed
shortly by
KashiwazakiKariwa-7.
Similar
digital I&C systems
are used in
Hamaoka-5.
Tomari-3, featuring
the first all-digital
reactor control
room, began
operations in 2009.
UK
SOUTH KOREA
In the UK at
Sizewell B, a
1,250-MW(e)
pressurized water
reactor, all automatic
functions of the
safety I&C systems
are digital, and in
the main control
room, all the
qualified displays
used in the humansystem
interface are
computerized.
RUSSIA
In Russia, Kalinin-3,
which was commissioned
in 2004, is
the first VVER-1000
equipped with digital
I&C safety systems
and digital process
control systems. In
addition, both its
main and emergency
control rooms have
hybrid human-system
interfaces. A dynamic
simulator was also
installed for the
purpose of testing
control functions.
In the Republic of
Korea, three 1,000MW(e)
PWRs that
recently came online
(Shin-Kori-1 and -2
and Shin-Wolsong-1)
all have fully digital
I&C safety and control
systems and hybrid
human-system interfaces
in the control
rooms.
