System 80

System 80

System 80 is a pressurized water reactor design by the Westinghouse Electric Company.

ystem 80+

An updated version of the plant has been designed which was given a "+" at the end of the name. This indicates an "evolutionary" plant design - changes were made to improve costs and safety. It has a 2-loop design and can run on a 100% MOX fuel core.

The control rods differ by using both 12 finger CEAs (control element assemblies) and 4 finger CEAs. The 12 finger ones are more reactive and only used for shutdown, while the 4 finger CEAs are used to control reactivity smoothly during operation.

The System 80+ was the design basis for the Korean Standardized Nuclear Plant, and contributed many features to the AP1000 as well.

The NRC has certified the System 80+ for the U.S. market, but Westinghouse no longer actively promotes the design for domestic sale. [NRC. [http://www.eia.doe.gov/cneaf/nuclear/page/analysis/nucenviss2.html#_ftn4] .]
