A collaboration between St. Louis-based Ameren Missouri and Westinghouse Electric Corporation to develop small modular nuclear reactors was passed over Tuesday for initial

funding by the U.S. Department of Energy.

The DOE will, instead, fund a similar project by Babcock & Wilcox and the Tennessee Valley Authority. The Ameren/Westinghouse partnership was seeking $452 million in funding to build the SMR's alongside the utility's Callaway county reactor.

Westinghouse Electric Corporation and St. Louis-based Ameren Missouri will collaborate on developing small modular nuclear reactors, or SMR’s, and will seek to build them at Ameren’s Callaway County plant.

Westinghouse officials say they’ll apply for $452 million in federal funding.  Plans are to build at least one and possibly five SMR's alongside Callaway’s current reactor, and to build more SMR’s at the site for export.  Governor Jay Nixon (D) described the economic potential as enormous.
