Workers have installed the fourth segment of the inner steel containment for Unit 1 of the Lianjiang nuclear power station under construction in Guangdong province, southern China, the China Nuclear Energy Association (CNEA) said.

Next steps will include capping the steel containment with the installation of the fifth segment, the dome.

The inner containment is a critical safety component for a nuclear plant. It is designed to prevent radioactive leakage into the environment in the event of an emergency.
