According to the IAEA website, on Jun 14, 2016, the NFCIS held information pertaining to 650 different facilities, located in 54 countries throughout the world.
The information is gathered through questionnaires that participating countries respond to, every few years, regarding their nuclear fuel storage and production facilities.

This database could help the International Atomic Energy Agency maintain an element of control over these hazardous weapons and allow one system to monitor the worldwide supply.
Since 1957 the IAEA has implemented additional offices in Toronto, Canada, Tokyo, Japan, New York City, United States of America, and Geneva, Switzerland.
The goal of the International Atomic Energy Agency is to maintain nuclear technology around the world in a safe, controlled and peaceful manner.
