Industry human performance indicators comparison project

Many commercial nuclear power plants have attempted to compare their level of human performance with other commercial nuclear power plants. Because of differences in the way plants measure their levels of human performance, very few plants could compare themselves reliably with other plants, including plants in the same fleet. The definition of an error, an event, or a station or department level event free day reset varied widely. In March 2005 representatives of 23 plants from 12 utilities met to discuss the development of a common set of human performance indicators so plants could compare their human performance with other plants. By late 2005 a basis document was completed that defined several key human performance indicators that could be used to compare the level of human performance among plants. Throughout 2006 17 plants voluntarily provided quarterly key performance indicators as defined by the basis document to INPO. This paper describes the basis document and the operating experience from the data collection.
