Conclusion of a Contract for Completion of Unit 3 and 4 at Mochovce NPP

Date: 12. 6. 2009

On Thursday, June 11, 2009 a contract for completion of the nuclear island of Unit 3 and 4 at Mochovce NPP was signed in Bratislava between ŠKODA JS a.s. and Slovenské elektrárne, a.s. Thereby a two-year period of negotiations and preparations is crowned. ŠKODA JS is one of the five main contractors for this project.

Out of the four VVER 440-type units originally planned in the Mochovce locality, first two units were put into operation between 1998-1999. For the remaining under-construction and preserved Unit 3 and 4, the crucial part of mechanical supplies was delivered. The plant is a property of Slovenské elektrárne, a.s., whose majority owner became Italian company ENEL in 2006.

For ŠKODA JS, the supply of key systems for the Mochovce NPP completion project represents a great success that underlines the leading position of the company among Czech suppliers of large investment units. Contraction of this project guarantees development and expansion in the field of nuclear power industry in future years. It will also enable raising up a new generation of specialists, who will subsequently apply their skills and knowledge within the planned construction of new units at Temelín, Bohunice and Dukovany NPP.
