The EUCG Nuclear Committee is a cooperating group of nuclear plant representatives. Their primary goal is to optimize costs and reliability performance of participating plants. Membership currently includes representatives of nuclear plants operating in the United States, Canada, China, Eastern Europe, Mexico, and Spain.

To achieve these objectives, the Nuclear Committee operates a database for comparing nuclear plant costs, staffing, and performance data. This database was originally developed in 1986 and is recognized as the best, most comprehensive source of nuclear plant data in the world. This database is updated annually and distributed to participating members.

The database includes:
    Plant and Unit Performance and Cost Data
    Nuclear Operating Cost Data — Base and Outage
    Capital Cost Data and Capitalization Policy Information
    Staffing Data

All data is requested via a web-based program. Data is delivered to participants on a give-to-get basis via a web-based query and reporting tool.
