Works on Concrete Casting Performed at Baltic NPP
OREANDA-NEWS. December 14, 2012. At the construction site of the Baltic nuclear power plant there were performed works on the concrete casting of the Unit 1 foundation plate. Works were carried out by the specialists of JSC United Energy-construction Corporation under the supervision of the branch of OJSC Concern Rosenergoatom Baltic NPP construction Directorate and the general contractor JSC NIAEP.
Pouring high strength concrete B40W6F100 was conducted in shifts. A total of 1,700 cubic meters of concrete was poured. The height of the reactor building foundation plate rose from the mark – 8.800 m to 7.150 m.
"Concreting is being performed in the cold period, today the temperature is minus 6 degrees. In order to prevent freezing and loss of concrete properties there are applied concrete antifreeze additives and hydrothermal processing of reinforcing cage of the foundation plate ", said the Head of Technical Supervision of the Capital Construction of Baltic NPP construction Directorate Vyacheslav Dynin. He noted that for today it is held of compliance monitoring of hydrothermal regime and concrete curing. After the poured concrete attains strength, builders will start construction of the protective lining of the reactor cavity and installation of the "core catcher", the details of which are arriving at the construction site.
For reference:
Baltic NPP is located in the eastern part of Neman District in Kaliningrad Region, 13 km to the south-east of Neman and 22 km to the west of Krasnoznamensk, close to the Lithuanian border. The plant is of AES-2006 design (chief designer JSC SPbAEP) with two VVER-1200 units with the installed capacity of 1200 Mw for each unit. The commissioning of unit 1 is scheduled for 2016, the second unit – for 2018.
