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.
Thermal Neutron Capture Gamma-rays
This site presents the energy and photon intensity of gamma rays as seen in thermal-neutron capture in two tables, one in ascending order of gamma energy and a second organized by Z, A of the target.
International Regulatory Network
The International Regulatory Network (RegNet) is the Portal for web-based international cooperation among nuclear safety and security regulators.
TCLAC
This site provides a shared space for programme management to project team members of technical cooperation projects for the region of Latin America and the Caribbean.
TC PRIDE
The Technical Cooperation Project Information Dissemination Environment (TC-PRIDE) system provides detailed information about all ongoing and completed technical cooperation projects, as well as various summary financial reports.
Stopping Power
This resource gives access to a collection of data, graphs and computer programmes dealing with the ranges of various ions (from protons to uranium) in materials.
Spallation Models
This site provides access to the IAEA Benchmark of Spallation Models.
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.
IAEA/WHO Network of Secondary Standards Dosimetry Laboratories (SSDL)
The joint IAEA/WHO Network of SSDLs was established in 1976 to improve the accuracy of radiation dosimetry. Through laboratories designated by IAEA Member States, the Network enables national dosimetry standards to be traceable to the international system of units (SI).
Safeguards Support Programme Information and Communication System (SPRICS)
SPRICS gives Safeguards Member State Support Programme stakeholders access to task proposal information, task information, meeting information, and point of contact information.
SAGSI on Nucleus – Standing Advisory Group on Safeguards Implementation (SAGSI)
SAGSI advises the IAEA Director General on the technical aspects of IAEA safeguards.
Research Reactor Material Properties Database
The RRMPDB is a compilation of reports on properties of structural and component materials used in research reactor cores.
Reference Products for Environment and Trade
This site gives access to more than 90 reference materials to assist IAEA Member State laboratories in enhancing the reliability and comparability of measurement results obtained by nuclear analytical techniques.
