Nuclear power    engineering

We supply control and management systems for large and small nuclear reactors and related nuclear technologies, including services. We are an established player in the field of nuclear technology management supplies, both at home and abroad.

Our company's know-how includes knowledge of the legislation of the country and compliance with strict international rules. We are currently meeting the requirements of the legislation of individual state authorities for nuclear safety in the Czech Republic and in 6 other countries around the world.

Control and management systems

Project solutions for functioning and newly built nuclear power plants

Our own development

Solutions for primary, secondary and non-unit parts of nuclear power plants on our own SandRA platform

Tradition and stability

Nuclear technology management since 1972 to 30% of nuclear units in the EU and 10% worldwide

Large nuclear reactors

We supply control and management systems to operated and new nuclear power plants in the Czech Republic and abroad. We develop, design and manufacture control systems for various types of nuclear reactors, specifically focusing on nuclear power plants with pressurized water reactors.

We offer partial and complex solutions for the management of technological operating sets of the primary and secondary circuit and auxiliary operations of the power plant, including some safety systems and several other special systems.

We provide design, production, testing, assembly and commissioning, including the implementation of detailed design according to the customer's general specifications. Preparation of production documentation and qualification of the delivered equipment according to the legislation valid in the country of the end user are a matter of course for us.

SandRA Z100 and Z200

Reliable control system with life cycle management for the implementation of functions in all safety classes

Small and research nuclear reactors

We supply and modernize control and management systems for low-power reactors and research reactors. We work on projects in the Czech Republic and abroad. We cooperate with research organizations that participate in the development of 4th generation reactors.

We provide design and supply of control systems for a specific sector of research and school reactors and provide comprehensive services in the modernization of control and management systems.

For this specific sector of small, research and school reactors, we provide detailed design according to the customer's framework specification, production, testing, assembly and commissioning, including qualification of the supplied equipment according to the legislation valid in the end user's country.


We use the SandRA platform in solutions for small reactor

Maly Reaktor

Service and maintenance

We design equipment especially for our own projects, at the same time we offer our know-why and know-how to other customers as well. These are mainly designs and supplies of special electronic and electrical equipment for nuclear power plant technology management applications. We develop and manufacture special power blocks, such as controlled rectifiers, converters, inverters, etc.

We provide customers with support and services in the area of project preparation, licensing, equipment qualification with regard to legislation, training, life extension of the control system. We take care of customers in the supply and repairs of spare parts in the form of warranty, post-warranty and guaranteed service.
