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.
Country Nuclear Power Profiles
The CNPPs cover background information on the status and development of nuclear power programmes in countries with nuclear plants in operation or plants under construction, and in countries actively engaged in planning such programmes.
Contact Experts Group Database
This database is currently in the process of being transferred to the International Nuclear Information System (INIS). It has been developed to support informational exchange between the countries participating in the IAEA Contact Expert Group for International Radioactive Waste Projects in the Russian Federation (CEG).
Computer Index of Neutron Data
CINDA is a database that contains bibliographic references to measurements, calculations, reviews and evaluations of neutron cross-sections and other microscopic neutron data.
Charged Particle Cross Section Database
The Charged Particle Cross Section Database is intended for medical radioisotope production and for diagnostic radioisotopes and monitor reactions.
Basic Professional Training Course on Nuclear Safety
??The Basic Professional Training Course on Nuclear Safety (BPTC) is intended to provide a broad overview of all the safety concepts and their application to nuclear power plants and research reactors design and operation.
Atomic and Molecular Bibliographic Data System
AMBDAS is a database that provides bibliographic atomic, molecular and plasma-material interactions data of interest to fusion research.
Atomic Masses, Q-values, and Threshold Energies
This Q-value calculation programme allows you to calculate reaction Q-values and threshold energies and decay Q values based on the 1995 Update to the Atomic Mass Evaluation and to retrieve other quantities contained in this evaluation.
Atomic Mass Data Center
The Atomic Mass Data Center and its electronic bulletin are tools for the exchange of information on experimental masses, evaluation of masses, extrapolation of masses, and theoretical masses.
Atlas of Neutron Capture Cross Sections
The NGATLAS contains neutron capture cross sections in the range 10-5eV - 20MeV as evaluated and compiled in recent activation libraries.
Asian Nuclear Safety Network
The primary objective of the ANSN is pooling, analysing and sharing nuclear safety information, existing and new knowledge and practical experience among the participating countries.
Application of Safeguards to Geological Repositories
The main objective of the Application of Safeguards to Geological Repositories (ASTOR) Group of Experts is to support the IAEA’s objective to obtain credible assurance that nuclear material and technology associated with geological disposal activities are not diverted from peaceful nuclear uses.
Accelerator Knowledge Portal
This site is a knowledge resource for and by the accelerator community.
