The AES-2006 design is the basis for implementation of the General Siting

Plan “roadmap”

2626

● Thermal power has been increased up to 3200 MW and Efficiency factor (gross) of a power unit has reached 36.2%, due to:

▬ elimination of excessive conservatism▬ improvement of steam turbine thermal circuit▬ improvement of steam parameters at the steam

generator outlets and decrease of pressure losses in steam lines

● Economic efficiency has been improved by means of:▬ optimization of passive and active safety systems

used in AES-91 and AES-92 designs▬ unification of the main equipment;▬ decrease of materials consumption

AES-2006 – the targets reached
