Power Reactor Information System

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.

PRIS 2.0 includes a new version of PRIS Statistics available to all registered PRIS users. In case you experience problems printing reports from PRIS Statistics, please ask a user with administrative privileges to log on to your Windows machine in order to download the required ActiveX control.
