GE design for Korean plant

South Korea’s Doosan Heavy Industries & Construction will manufacture and install two GE-designed 1,455-megawatt, N2R steam turbines for two new reactors at the Shin Kori Nuclear Power Plant.


Under an agreement with GE, South Korea’s Doosan Heavy Industries & Construction will manufacture and install two 1,455-megawatt, N2R steam turbines for two new reactors at the Shin Kori nuclear power plant in Kori, south eastern Korea. GE will design and provide key components for the machines, which will be the largest 60-hertz steam turbines in the world.


Shin Kori is operated by Korea Hydro and Nuclear Power (KHNP), a subsidiary of Korea Electric Power Corporation (KEPCO).


Doosan is supplying the GE-designed steam turbines as part of its contract with KHNP to help build the new nuclear power plant at Shin Kori, a two-unit pressurised water reactor facility. The machines will feature a new GE-designed, 52-inch last-stage bucket group and a three-dimensional aero steam path.


The two steam turbines will be installed as units 3 & 4 at Shin Kori, with a combined output of 2,900 megawatts. Doosan’s steam turbine order is the latest project in South Korea for GE, which has provided more than half of the Korean nuclear industry’s steam turbines.


Under the new contract, GE will design the new steam turbines as well as provide Doosan with low-pressure section buckets, a Mark VI turbine controls package, excitation components and a stator leakage monitoring system. The scope of the contract also includes technical services, spare parts, training and performance testing. The equipment will be shipped to Korea in January 2010 and the new units will begin commercial operation in 2013.

GE says the N Series steam turbines are two-stage, reheat, tandem compound designs for nuclear applications up to 1,500 megawatts. N Series turbines feature monoblock rotors, delivering reliability and low maintenance costs.
