Mitsubishi Nuclear Energy Systems Inc. (MNES) was awarded contracts to provide its water jet peening (WJP) service at two nuclear power plants.

The contracts are for work at the Wolf Creek Generating Station in Kansas and the Ameren Missouri Callaway Energy Center in Missouri.

The entire process can be conducted underwater and uses only high-pressure water. No foreign materials or heat is applied.

MNES will be responsible for the project management, and will work with contractors AZZ WSI and Structural Integrity Associates Inc.
