AmerenUE to seek nuclear plant permit

5 April 2007 — AmerenUE will work with UniStar Nuclear to take the first step to apply for a license to build and operate a new nuclear plant, the company said.

Under the agreement, the two companies will work together in preparing a combined construction and operating license application (COLA) for filing with the U.S. Nuclear Regulatory Commission (NRC). A COLA application describes how a nuclear plant would be designed, constructed and operated.

Ameren officials said in a release that preparing a COLA, the first step in the regulatory licensing process, does not mean a decision has been made to build a nuclear plant.

AmerenUE and UniStar Nuclear need to submit the COLA to the NRC in 2008 to be eligible for incentives available under provisions of the 2005 Energy Policy Act.

UniStar Nuclear selected the U.S. Evolutionary Power Reactor (U.S. EPR) design as its technology of choice and is working with nuclear utility licensees across the nation to explore suitable sites for U.S. EPR nuclear plants, including Ameren’s nuclear plant in Callaway County, Mo. AmerenUE has operated the single-unit nuclear plant in Callaway County since 1984.

UniStar Nuclear is a new joint venture, headquartered in Annapolis, Md., equally owned by Constellation Energy Group and AREVA Inc. UniStar Nuclear helps develop, license, construct and operate new, standardized nuclear units.
