It is widely recognised that a good set of performance indicators can provide a partial, but important and useful measure of how well a nuclear plant is managed overall. The WANO performance indicator programme supports the exchange of operating experience information by collecting, trending and disseminating nuclear plant performance data in key areas. The data is gathered for a set of quantitative indicators of plant performance.

WANO published and distributed the first performance indicator report in April 1991. In 1993, reporting of data began for all reactor designs. Current worldwide performance indicators are published annually, including historical trends, in a WANO Performance Indicator Tri-fold Report.

These indicators are intended principally for use as a management tool by nuclear operating organisations to monitor their own performance and progress, to set challenging goals for improvement, and to gain additional perspective on performance relative to that of other plants.
