PRIS covers two kinds of data: general and design information on power reactors, and information about operating experience with nuclear power plants. General and design information covers all reactors that are in operation, under construction, or shut-down in IAEA Member States, and in Taiwan, China. Data on operating experience cover operational reactors, and historical data cover shutdown reactors, in IAEA Member States and in Taiwan, China. In these areas PRIS is considered the most complete and authoritative source of statistical data
