BWROG Mission

◇ The mission of the Boiling Water Reactor Owners’ Group (BWROG) is to provide a forum, in the spirit of partnership with GE-Hitachi Nuclear Energy, which allows its member utilities to maintain and improve plant safety, achieve higher plant reliability, minimize and share costs, facilitate regulatory interaction, and effectively apply limited technical resources for mutual resolution of issues applicable to two or more members. (Ref. BWROG Charter Sec. II)

￭ The BWROG is a utility lead organization designed to benefit the utility members. The member utilities decide what activities get worked and the timeline for those activities.
