Welcome to PRIS

The Power Reactor Information System (PRIS) is a comprehensive data source on nuclear power reactors in the World. It includes reactor specification and performance history data. The monthly power production and power losses data have been recorded in PRIS since 1970s. Due to detailed classification of energy losses and comprehensive outage coding system, a set of internationally accepted performance indicators are calculated from the PRIS performance data.
