First steam generator for Leningrad II

Installation of the first of the four steam generators at the
Leningrad II nuclear power plant in western Russia will be completed
within the next few days, general designer of the new plant
Atomenergoproekt (AEP) said today. Installation of the remaining three
steam generators – manufactured by Atomenergomash subsidiary ZIO-Podolsk
– is scheduled to be completed by the end of September, AEP said.

Leningrad Phase II is a new nuclear power plant adjacent to the
existing Leningrad nuclear plant site. Two AES-2006 design nuclear units
are being built there, which should begin operation in 2016 and 2018
respectively. Two further AES-2006 units are planned for the site. Each
AES-2006 unit will employ four steam generators.

Steam generators are used in pressurized water reactors to transfer
heat from the reactor’s primary coolant circuit to a secondary circuit –
turning water into steam that goes on to drive turbines and generate
electricity.
