Callaway & Wolf Creek - The SNUPPS Plants


In the 1970's, 4 utilities - Kansas Electric, Northern States Power, Rochester Gas & Electric, and Union Electric - started on a path to design and build 6 standardized units. Due to depressed electrical demand following the oil embargo and the uncertainty involved with licensing new reactors following the TMI event, NSP and RG&E cancelled the Tyrone and Sterling facilities. Kansas Electric and Union Electric, with Bechtel as the architect-engineer and Westinghouse as the nuclear equipment supplier subsequently completed the design, built, and started up the Wolf Creek and Callaway plants. Both are 4 loop Westinghouse PWRs.

Callaway is located in Fulton county about 100 miles northwest of Saint Louis, Missouri. Ameren Corporation provides a page about Callaway with history. Below are some photos of the Callaway facility.
