Nuclear Energy: Reliable Solutions for a Safe Future

With extensive experience in both domestic and international markets, we offer top-notch solutions for nuclear energy. Our certified products meet the highest standards of quality and safety, as confirmed by successful deliveries to the nuclear power plants in Dukovany and Temelín. We specialize in the supply of fittings that undergo rigorous testing, including seismic testing, to ensure their reliability in the most demanding conditions.



We will complete Dukovany for you safely, reliably, and on time. We are KHNP – a global leader in reliable energy.

The Czech Republic deserves a reliable, transparent, and technologically advanced supplier for the new block of the Dukovany power plant. Only then will this investment make sense and benefit future generations of your beautiful country.

The company has passed the audit of the tender winner for the construction of the Dukovany nuclear power plant and has been included on the vendor list.

Our Experience in Nuclear Energy

We have extensive experience in the nuclear energy sector both in the Czech Republic and in international markets.
