NUCLEUS information resources

The IAEA's NUCLEUS information resource portal provides access to over 100 scientific, technical and regulatory resources, including databases, applications, publications and training material. As it is mainly meant for IAEA counterparts in the government, industry and scientific community, NUCLEUS hosts a number of resources that require registration. Many sites, however, can be accessed without a password.

ENDF Pre-processing Codes

The ENDF/B Pre-processing codes (PREPRO) is a collection of 16 computer codes designed to convert ENDF/B formatted neutron and/or photon data from the original distributed form to a form in which the data can be used in applications. 

ENDVER

ENDF File Verification Support Package. Experimental and evaluated nuclear reaction data are compiled world-wide in EXFOR and in ENDF format, respectively (see documents IAEA-NDS-1 and IAEA-NDS-10).

ENSDF Analysis and Utility Programmes

ENSDF Analysis and Utility programmes (ALPHAD, LOGFT, etc.)

Evaluated Nuclear Data File

Core nuclear reaction database containing evaluated cross sections, spectra, angular distributions, fission product yields, photo-atomic and thermal scattering law data, with emphasis on neutron induced reactions.

Evaluated Nuclear Structure Data File

ENSDF is a database that contains evaluated nuclear structure and decay information for over 3,000 nuclides.

Experimental Nuclear Reaction Data

This database, also known as EXFOR library, contains an extensive compilation of experimental nuclear reaction data, comprising data from more than 22,000 experiments. 

Siting

External Events Safety Section (EESS) portal

The EESS portal is a platform and working space for registered users that allows them to collaborate on extrabudgetary IAEA projects related to site evaluation and the protection of nuclear installations against external hazards.

Food Contaminant and Residue Information System

FCRIS is a resource on chemical food contaminants with a focus on Codex food standards and guidelines and on reducing the incidence of food trade rejections as a result of chemical contaminants and violative levels of residues.

Front Line Officer Network

Effective nuclear security detection systems and measures help to ensure the prevention and deterrence of criminal or unauthorized acts with nuclear security implications involving nuclear and other radioactive material out of regulatory control.

Fuel Incident Notification and Analysis System

Through the Fuel Incident Notification and Analysis System (FINAS), participating Member States share operational experiences to improve the safety of fuel cycle facilities.

Fusion Evaluated Nuclear Data Library

This Library contains selected evaluated nuclear data files in ENDF-6 format.

Fusion Portal

This site brings together all fusion activities organized by the IAEA.
