Case Study Hunterston B Nuclear Power Station

Hunterston B was in operation for 46 years and provided one gigawatt of the UK’s 7.9GW nuclear capacity, enough to power to 1.7m homes.

On the decommissioning project for the nuclear power plant owned by EDF, Somers Forge supplied the shaft and pinion forgings for the gearbox. Forging, heat treating and rough machining the shaft and pinion forgings. Pictured is the finished gearbox displaying the pinion.
