Missouri Gov. Jay Nixon and officials of two energy companies are preparing to make an announcement that could include plans for a second nuclear reactor in the state.
Nixon and leaders of Ameren Missouri and Westinghouse Electric are scheduled to make the formal announcement Thursday at a news conference in Jefferson City. Nixon's office says the announcement will be significant for energy development and economic growth in Missouri.
St. Louis-based Ameren Missouri operates Missouri's only nuclear power plant, located in Callaway County about 25 miles northeast of Jefferson City. Two efforts in recent years to expand nuclear power in Missouri have stumbled, largely amid opposition from consumers and industrial users over protections for electric ratepayers.
Nixon endorsed a previous nuclear power proposal in November 2010.
