VIDEO: Massive 350-tonne part on its way to Darlington
Wednesday, April 10, 2019
Refurbishing a nuclear reactor is a big job and an essential 350-tonne part is now on its way to the Darlington Nuclear Generating Station.
General Electric, one of the project partners for the Ontario Power Generation (OPG) Darlington Refurbishment, manufactured the 350-tonne stator. A stator is the stationary part of an electric generator that converts the rotating magnetic field into electric current. GE shipped the stator from its Poland factory earlier this month. The part is expected to arrive at Darlington in May, according to the latest Darlington Refurbishment Project Newsletter released Thursday, March 28.
OPG’s Darlington station has been in operation since the early 1990s and is approaching the midpoint of its operating life. Replacing critical components of the CANDU reactors will extend Darlington’s operating life by 30 years or more.
OPG began the first steps in the refurbishment of its four reactors at Darlington in October 2016, beginning with unit two. The refurbishment of unit two is scheduled to take until February 2020. After unit two returns to service, workers will move on to refurbish unit three. The stator component will be used during the unit three refurbishment, which is scheduled to start in 2020. That will be followed by refurbishment of unit one, and finally unit four — scheduled to be completed in February 2026.
