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 the 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 including some safety systems and several other special systems.
We provide:
- 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 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 the 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 belong to the fourth generation reactors. We work on projects in the Czech Republic and abroad and we also work with different organizations ensuring 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 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 also develop and manufacture special power blocks such 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 modernization of the instrumentation and control system of operated power plants and also on supply of new built blocks, we participate in modernization of I & C of research reactors in the Czech Republic and abroad, focusing within the following disciplines:
- I & C for the primary circuit of NPP
- I & C for the secondary circuit of NPP
- I & C common unit components
- I & C in auxiliary parts
- I & C for research reactors and small reactors
- Special Applications
Instrumentation and control system for the primary circuit of the nuclear power plants
We provide a complete supply of most control systems for the primary part of the nuclear power plants. You can find our systems in all safety classes of control systems (A, B, C according to EN 61226) and they are realized based on platform SandRA Z100 and Z200.

BOP (Balance Of Plant) control systems
We provide a comprehensive supply of control systems for BOP of NPP. You can find our systems in safety classes C control systems according to EN 61226 and those non-classified. The system is realized based on platform SandRA Synergy DCS.
These systems provide essential needs of nuclear power plant in spite of the fact that they belong to neither the primary nor the secondary part of the power station unit.
ZAT more reliable and sustainable solution is convenient for the operator. It unifies technical solution and centralizes operation control into few centres with permanent staff. Thanks to this the work which is necessary on the individual operating files is coordinated in a better and more efficient way.
I & C of BOP includes:
- I & C system of NPP water control
- Pumping and cleaning stations of waste water
- Technological and sewage sink plant
- Damping and measuring object of waste water
- Energy recovery systems for gravity waste water from NPP
- Industrial gas management
- Industrial water supply
- Valve chamber reservoirs
- Heat exchanger
- Stations of the cold source
- Low-pressure compressor station
- Auxiliary boiler room
- Water treatment for cooling tank with splash
- Control system for non-unit own consumption
- Lubricating oil and diesel fuel management
