Automationfor Nuclear Power Generation

What do we do?

We provide instrumentation and control system for nuclear power plants. In the past, we have implemented a number of projects not only in the Czech Republic but also abroad. We are among the four companies in the EU, which develops, manufactures, designs and provides their own instrumentation and control systems for the primary circuit of the nuclear power plants. The Czech Republic, thanks to ZAT, belongs among the world suppliers of the most advanced control systems for nuclear power plants.

  • Low operating costs Through easy maintainability of systems we will reduce your operating costs
  • Individual approach We allow connection of other systems of different world manufacturers and strive to meet all customer requirements and wishes

Offer of Services

Refurbishment of existing NPP

We modernize instrumentation and control systems of power plants in the Czech Republic and abroad with a focus on plants with pressurized water reactors. We develop, design and manufacture instrumentation and control systems for various technology of nuclear reactors VVER 1000 and VVER 440.

Advantages of our systems:

  • Operational reliability
  • High comfort of diagnostics
  • Substantial reduction of the maintenance
  • Easy control and status check

We provide:

  • Installation of the supplied equipment and its commissioning
  • Tests
  • Customer service

Construction of new nuclear power plants

We supply instrumentation and control systems for power plants in the Czech Republic and abroad with a focus on plants with pressurized water reactors. We develop, design and manufacture control systems for various technological units of pressurized water nuclear reactors.

We offer standardized and comprehensive solution for the control of technological operation sets of the primary and secondary circuits and auxiliary circuits of the power plant, with the exception of safety systems (reactor protection systems) and several other special systems.

We provide:

  • The design, manufacture, testing, installation and commissioning
  • Detail design according to customer's framework specification
  • Manufacturing documentation
  • Qualification of supplied equipment, according to the law of final destination country

Shutdown of nuclear plants

We focus on the monitoring and control of special technologies and equipment that are used in a process of terminating the life cycle of plants.

This segment of the market is just developing and we are currently working on the preparation of products which will be applied in this segment.

Research and small reactors

We modernize systems of instrumentation and control of research reactors and low power reactors, which belongs to the fourth generation reactors. We work on projects in the Czech Republic and abroad, and we work with different organizations which ensure construction of new reactors.

We provide:

  • Design and supply of control systems for specific sector of research reactors, so-called school reactors
  • Comprehensive services in the modernization of instrumentation and control systems

Special applications

We design and deliver special electronic and electrical equipment for many applications for technology instrumentation and control of nuclear power plants. We develop and manufacture a special power blocks as controlled rectifiers, converters, inverters, etc.

We design the equipment especially for our own projects, but we also offer our know-why and know-how to other customers.

Specialization

We focus on the modernization of the control system of operating power plants and also on supply of new built blocks, we participate on the modernization of I & C research reactors in the Czech Republic and abroad, focusing within the following disciplines:

Monitoring Systems for the primary circuit of the nuclear power plants

BOP (Balance Of Plant) control systems

We provide a comprehensive supply of control systems for BOP of NPP. With our systems you encounter in security classes C control systems according to EN 61226 and those classified.

These systems provide essential needs of nuclear power plant, even when neither the primary nor the secondary part of the power station block.

Reliable and sustainable solutions ZAT is convenient for the operator. Technical solution unifies and centralizes operations into few centres with permanent staff. Thanks to this the work which is necessary on the individual operating files is better and more efficiently coordinated.

I & C of BOP includes:

  • I & C system of water control of NPP
  • Pumping stations and cleaning of waste water
  • Sink technological and sewage
  • Damping and measuring object of waste water
  • Energy recovery systems for gravity waste water from NPP
  • The economy of industrial gases
  • Industrial water supply
  • Valve chamber reservoirs
  • Heat exchanger
  • Stations of the cold source
  • Low-pressure compressor station
  • Auxiliary boiler room
