GE Steam Power announced today that it has designed and manufactured the largest-ever (75-inch) last-stage blade for its Arabelle low-pressure rotor. The blade will enable the Hinkley Point C nuclear power plant under construction in Somerset, England to produce 3.2 GWe of CO2 free power, GE said. Once completed, this Arabelle steam turbine will be the most powerful nuclear steam turbine in operation. It was tested at GE's factory in Belfort, France.
