A contract won by a joint venture between Canadian reactor company Candu Energy and construction group Aecon for refurbishments at Ontario Power Generation’s (OPG) Pickering nuclear power station will be worth an estimated at CAD2.1bn ($1.46bn, €1.4bn), Candu Energy parent company AtkinsRéalis said.

According to AtkinsRéalis the contract includes CAD1.1bn for early works and roughly CAD1bn for the project’s definition phase.

The contract covers critical engineering, procurement and execution planning activities to extend the lifetime of the four commercial Candu heavy water reactor units at Pickering, about 45 km east of Toronto.
