The lower half of the inner steel liner for the containment dome has been lifted into place for Unit 7 at the Tianwan nuclear power station under construction in Jiangsu province, eastern China.
The dome is part of the reactor building’s physical protection system, which is designed to withstand high external and internal pressures and protect against radiation release.
Russian state nuclear corporation Rosatom, supplier for the Tianwan-7 project, said the 390-tonne component was placed on top of the previously installed inner containment building steel dome, part of the inner hermetic protection system.
