The first large-sized equipment was moved into the building in the machine room of the 3rd Power Unit of the Akkuyu Nuclear Power Plant. The Feed Water Storage Tank, an important component of the heat exchange equipment of the turbine installation, was first brought to the turbine building by an automatic wheeled platform. The experts then moved the tank to the maintenance level of the turbine with a self-propelled crawler crane with a lifting capacity of 1300 tons.
The Feedwater Storage Tank, a thick-walled vessel weighing 259 tons and 40 meters long, was transported in pieces with load-carrying equipment due to its large size. After the equipment is placed on the supports foreseen in the project, its assembly will be carried out.
AKKUYU NUCLEAR A.Ş. General Manager Sergei Butckikh said regarding the issue.
We are gradually preparing the engine room for the installation of the main equipment of the turbine plant of the 3rd Power Unit of Akkuyu NPP. The main technological level, which is 18,2 meters above the building floor, has been made capable of carrying the load of heavy equipment. Therefore, the Feed Water Storage Tank was transported directly to the turbine building after unloading and necessary customs procedures at the Eastern Cargo Terminal. After the installation of special support structures, the expert team will place the tank in its final position and weld the two parts of the tank body together. At the same time, concreting of the engine room walls is ongoing.
The Feed Water Storage Tank provides the necessary water reserve for the feed pumps of the nuclear power plant during the start-up and operation phases. The tank also stores the water discharged from other equipment in the engine room via the steam separator, superheaters and high-pressure heaters.
The equipment, which has a lifespan of at least 60 years, is designed to cover the entire operational life cycle of the VVER-1200 reactor power unit. The equipment is manufactured at the ZiO-Podolsk manufacturing plant, which operates within Rosatom's mechanical engineering division.
