Russian company JSC AEM-technology on Friday said it has started manufacturing two sets of steam generators for the third and fourth 1,000MW nuclear power units to be set up at Kudankulam in Tamil Nadu.
According to JSC AEM-technology, blanks for two sets of steam generators have to date been delivered and machining work for steam generator body shells and large branch pipes have begun.
"After inspections of shell blocks being conducted in the presence of the customer's representative, it is planned to start the assembly of SG (steam generator) bodies," the company said.
The steam generators' body is a horizontally oriented vessel with two elliptical end heads, in the middle of which hot coolant supply and removal headers are located.
According to the company, the steam generators will be shipped to India in 2018.
