Doosan Heavy Ind. sells equipment to largest U.S. nuclear power plant

SEOUL, May 22 (Yonhap) -- Doosan Heavy Industries and Construction Co. said
Friday that it has sold nuclear power plant equipment to the largest nuclear
energy generating facility in the United States.
The company said it has shipped the equipment composed of control element drive
mechanisms (CEDMs) and replacement reactor vessel heads to the Palo Verde nuclear
power plant in Tonopah, Arizona, which has a production capacity of 1,400 MW of
electricity.
The sale marks the first time Doosan has exported such equipment, including CEDMs
and reactor vessel heads, according to the company.
A reactor vessel head is used to maintain the pressure resistance of a coolant,
while a CEDM is a device used to control the degree of a nuclear reaction.
A total of 89 sets of CEDMs are installed on one reactor vessel head, Doosan
officials said.
Doosan won the right to supply the Arizona plant with control element drive
mechanisms in March 2006.
It usually takes an average of two years to manufacture the equipment for one
nuclear power plant unit, Doosan officials said.
The equipment, which has been recently shipped from Doosan's plant in Changwon,
South Gyeongsang Province, will be installed on one of the three units at the
Arizona plant.
Two additional shipments for the other units will be made in turn at six-month
intervals.
The South Korean company said that the latest shipment to Arizona is the fourth
export of nuclear equipment to the U.S. after it sent four steam generators to
the Sequoyah nuclear plant in 1999.
