Modernisation of the Cernavodă nuclear power plant in RomaniaPublished 16/9, 2019 at 15:32
Romania’s only nuclear power plant is located in Cernavodă, a small town near the Black Sea coast.
The power plant consists of two blocks and produces about 20% of the electricity for the entire country. One of these blocks is now being modernised thoroughly, and for this purpose around 400t of concrete had to be decommissioned in a controlled manner under the strictest safety conditions.
The Romanian company Diamond Drilling SRL, which amongst other equipment, used machinery from Tyrolit to complete the task including the dismantling. Its main assignment was to cut and remove 22 running meters of reinforced concrete walls, 4.5m high and 750mm thick, as well as 9m x 5m high concrete columns with basic measurements of 2.5m x 1.5m and 1.5m x 1.5m. Diamond Drilling SRL used the electric wire saws WCE14 and SB-E as well as the WSE2226 wall saw from Tyrolit to successfully complete the job.
Despite a very hard concrete quality (HPC 120MPa), as well as bad weather conditions and temperatures below zero, it was possible to cut the project time in half. The employees of Diamond Drilling SRL using the machines from Tyrolit thus proved that even the toughest conditions are no problem for them.
