Main Project

Mochovce Nuclear Power Plant is very close to our heart

“ENSECO pipelines are installed across the entire nuclear island of Units 3 and 4 at Mochovce.”

500

Workers

We have managed approximately 500 workers and another 250 workers under the management of our subcontractors.

1509

Tons of installed materials

We have procured, supplied and installed materials with the total weight of 1 509 tons.

10722

Valves

We have installed 10 722 valves and our work is visible in both units of the power plant.

40

Systems tested

During commissioning, we have performed non-active testing of 40 technological systems.

9646

Pipelines

We have installed a total of 9 646 pipelines in both units.

5

Main systems

Works involved 5 main elementary systems at all project stages.
