Our company is participating in modernization of nuclear power plant Paks where we supply a new control system for all four units. We are currently handing to be dispatched a modernized system of group and individual control of regulation mechanisms of nuclear reactor VVER 440 RRCS (Reactor Rod Control System) and a system of reactor power control RCS (Reactor Control System) for unit 3. These systems are intended for regulation, suspension or slowing down of fission reaction in reactor core and they are a part of entire I&C primary circuit system.
The RRCS and RCS systems increase technical level of the VVER 440 unit equipment. From the operator´s point of view they are, compared to the original systems, advantageous mainly thanks to their higher operation reliability, high diagnostics conveniences, substantial reduction of maintenance volume as well as easier control and check of state performed by the reactor control operator. Systems of the latest generation realized by our company for VVER 440 are based on platform SandRA Z100 intended for realization of the systems related to safety of nuclear power plant.
The contract follows previous successful supplies of identical systems for units 1 and 2 of nuclear power plant Paks I. This power plant with installed power of 2000 MW is the only nuclear power plant in Hungary. Completion of the contract has been planned for May next year. We realize the contract for Hungarian client MVM together with company ŠKODA JS.
„After completion of realization and putting the third unit into operation our RRCS system will be successfully operated on ten nuclear reactors with VVER 440 technology and eleven nuclear reactors with VVER 1000 technology in four countries. In addition to this we have five further RRCS systems for VVER 440 technology under contract and the realization is supposed to have been completed in the course of two following years,“ says Karel Stočes, Director of Nuclear Power Engineering Division.
