Flushing of the primary cooling system has begun at the Tianwan-7 nuclear power plant under construction in Jiangsu province, eastern China, according to Russia’s state nuclear corporation Rosatom.
The operation involves pumping demineralised water through the circuits – including the active and passive safety system – to remove construction debris. It is the last step in installing the primary system.
Rosatom said the next stage will be assembly of the reactor system for the VVER-1200 pressurised water reactor (PWR) plant.
