Doosan & GE focus on nuclear turbines

20 July 2010

Doosan Heavy Industries & Construction Co., Ltd. of South Korea and General Electric have announced a long-term agreement that extends their global cooperation in the development of next-generation nuclear and fossil steam turbines and generators. The immediate focus will be the development of larger output turbine-generators for South Korea’s next generation nuclear reactors, according to company statements.

GE and Doosan have collaborated in nuclear and fossil steam turbine and generator projects since 1976, resulting in more than 19GW of fossil and 14GW of nuclear installed capacity in South Korea. Most recently, the two companies have designed and are producing what will be the largest output, 1455MW, nuclear steam turbine and generator in a 60-hertz application. (See article korea-s-apr1400-employs-largest-ever-60hz-steam-turbine in our sister magazine Modern Power Systems for details on the turbine design and development).

The steam turbines will be used at Shin Kori 3&4, APR-1400 units that are due to begin commercial operation in September of 2013 and 2014, respectively. According to the schedule on Korea Hydro and Nuclear Power’s website, the reactor vessel at Shin Kori 3 is due to be installed in August 2010.

“This agreement strengthens our relationship to develop advanced designs for the next generation of steam turbines and generators in South Korea and globally,” said Dongsoo Suh, executive vice president and head of Doosan’s Power Plant Business Group.
