The know-how of project solutions from large units is also used for both research and small reactors
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.
Advantages of our deliveries
- Compliance with legislation and nuclear safety requirements
- Verified design of technical solution with regard to operational safety
- Documenting procedures in each implementation step (verification and validation of the design)
- Long-term technical support and service
- Implementation processes according to established nuclear safety culture
- Ensuring cyber security within the company, project and technical means
- Integrated quality management system and established processes
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.
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.
