MESSAGE (ENGLISH VERSION)

Westinghouse to Upgrade Temelín's Control and Monitoring Systems

In terms of technical complexity, it will be one of the most demanding projects in the history of the

Czech Republic, worth billions of crowns. The important project must not disrupt the operation of

the key Czech emission-free power plant. Selected control and management systems will be

partially renewed and upgraded by Westinghouse as their original supplier. Westinghouse has the

greatest knowledge of its system, apart from CEZ itself, which strengthens the safe course of the

upgrade.

In 1993, the Government decided to complete two of the four Temelín generating units that were under

construction and to replace the original system with Westinghouse's then state-of-the-art digital control

and management system. This was one of the world's first links between an Eastern and American

project. Since the first unit was commissioned, it has operated here with only routine modifications and

updates. A part of the system will now undergo its first major upgrade.

“Although this is an upgrade of systems, negotiations with the existing supplier took more than a

year. Our first priority is of course to ensure safety, but we also insist that the work should not

affect the operation of Temelín itself. All this had to be carefully prepared and formulated in the

contract,” says Daniel Beneš, Chairman of the Board of Directors and Chief Executive Officer of ČEZ.

In practice, experts will replace some systems and some of the fixed equipment, including the buses and

control elements involved. Most of these are not only physically separated from each other, but also from

all external networks.

“In fact, it is a complex of several independently backed-up systems that have been operating

reliably at Temelín since 2000. This upgrade is not a solution to a sudden need, but a carefully

prepared step in the gradual renewal of the equipment with a view to the planned sixty-year and

possibly even longer operation. This is why the entire project is spread out until 2029,” explains

Bohdan Zronek, Member of the Board of Directors and Director of the Nuclear Power Division.

The contract for the control and management system upgrade was signed by representatives of ČEZ and

Westinghouse on Monday, September 13.

“This agreement requires full cooperation at all levels during the complete renewal of the affected

parts of the control system,” says Tarik Choho, President of Westinghouse Europe, Middle East and

Africa. “We are proud to be working with ČEZ on this significant upgrade of information and

control systems that will not disrupt the operation of this key Czech emission-free power source,"

he adds.

ČEZ has been preparing the control and management system upgrade project for three years, when

specialists specified the needs and, above all, the schedule of work. The physical work itself will start

together with Westinghouse this year, but some of the activities will only be possible during the planned

major outages for fuel replacement. The next one is due at Temelín in April next year.
