What is NUCLEUS?
NUCLEUS is the IAEA’s web portal for providing public access to over 100 scientific, technical and regulatory resources, including databases, websites, applications, publications, safety standards, training materials, and more. NUCLEUS makes it easy to search and browse the large number of resources made available online by the IAEA.
Many of the websites or website features available through NUCLEUS can only be accessed by users with a registered NUCLEUS account. Anyone can create a NUCLEUS account, which will be valid for all sites using the common single-sign-on system of the portal.
Some NUCLEUS websites and features require additional privileges to be granted to users before they can be used. Site owners are responsible for granting users access to the protected parts of their websites.
