The long-lead items agreement requires GE Hitachi Energy (GEH) to supply the major components needed for developing nuclear power plants, including the manufacturing of ultra-large forgings, reactor pressure vessels and steam turbine generators.

The company said that initiating the procurement and fabrication of such schedule-critical components is necessary to assure their availability if Exelon decides to proceed with building a new plant.

Exelon is in the process of selecting a location in southeast Texas as a viable site as part of its application for a combined construction and operating license for the potential Economic Simplified Boiling Water Reactors (ESBWRs).

Andy White, president and CEO of GEH, said: We are very excited to be working with Exelon and appreciate the confidence the operator of the largest US nuclear fleet has placed in GEH.
