We want to supply the SandRA control system to all nuclear power plants in Hungary

We want to supply the SandRA control system to all nuclear power plants in Hungary

Last year, in cooperation with ŠKODA JS, we completed the replacement of the unit power control and control system and drives on all four production units of the Pakš I nuclear power plant in Hungary. “This is another nuclear power plant completely controlled by our SandRA control system. We also want to participate in the supply of controls for the planned completion of the Pakš II nuclear power plant," says Karel Stočes, director of marketing and sales of the Energy Division.

As part of our activities in Hungary, together with other Czech suppliers and economic journalists, we took part in a visit to the Pakš nuclear power plant organized by the Rosatom consortium at the end of February. In the opening presentation, the technical director of the nuclear power plant highlighted the range of supplies from Czech and Slovak suppliers during its reconstruction. "He rated our company as an excellent supplier of an excellently functioning digital system. He also mentioned the tender for turbine control and protection systems, where he talked about the participation of ŠKODA JS and ZAT companies," added František Kural, Marketing and Trade Manager of the Energy Division, who participated in the event together with Karel Stočes.

Journalists also viewed the main control room of the B4 unit and the common reactor hall for the B3 and B4 units. They also visited the reactor training center, where it is possible to simulate the operation of real parts of the equipment: reactor vessel, fuel rods, steam generator, main circulation pump and other parts, including technologies for the secondary circuit.

We are ready for supplies for the Pakš II NPP

The second day was devoted to discussions on the construction of Pakš II NPP units. Deputy director for completion of Rosatom S.V. Generalov informed the participants about the planned start of the process for selecting suppliers in April this year. The documentation for the building permit is currently being implemented, which is to be handed over by the authorities in the middle of this year, the issuance of the building permit is expected within twelve months.

"Even in the section dedicated to the completion of the nuclear power plant, we presented our project solutions and products for nuclear energy, including deliveries for Pakš I, and especially readiness for deliveries for Pakš II," states Karel Stočes. ZAT has significant references in the field of nuclear energy, the control systems of Příbram developers are deployed in nuclear power plants in seven countries in Europe and Asia. In total, this is 30 percent of nuclear power plants in the EU and 10 percent in the world. "Projects for nuclear power plants are currently being implemented in Finland, France and Armenia. As part of planned shutdowns, we also carry out service at nuclear power plants in our country and in Slovakia, where the ZAT control system is also deployed at all nuclear power plants," adds Karel Stočes.

On behalf of the Czech side, the companies ŠKODA JS a.s., Sigma Group a.s., Kabex a.s. and Essential Communication s.r.o. participated in the event. 

ZAT supplies for Pakš I NPP

Pakš I NPP blocks are controlled by SandRA Z101 and Z102 process stations, which contain special safety functions classified into the highest safety categories. These process stations implement the regulatory and safety system for controlling the drives of the reactor's regulatory cassettes. Its task is to regulate, slow down or, if necessary, stop the fission reaction in the reactor. The second system is the reactor power control system. Both systems are closely linked and work together. This delivery was carried out in cooperation with the company ŠKODA JS, and the delivered systems are crucial for the operation and ensuring the safety of nuclear power plants.
