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.

NuDat 2

NuDat 2 is a software that allows users to interactively search and plot nuclear structure and nuclear decay data. 

Photon and Electron Interaction Data

Photon Interaction Data (EPDL), Atomic Relaxation Data (EADL), Electron Interaction Data (EEDL), Excitation Data (EXDL) and Photon Anomalous Scattering factors (ASF).

Plataforma IberoAmericana Nuclear de Operadores en el área de Seguridad

This resource is a regional web-based collaboration platform supporting the development of Iberoamerican nuclear operators staff working community of practice.

Pointwise Data

​Temperature dependent cross sections for the ENDF/B-VII.1 library.

Post Irradiation Examination Facilities Database

This resource is a technical catalogue of Post Irradiation Facilities (hot cells) worldwide.

Power Reactor Information System (PRIS)

The Power Reactor Information System (PRIS), developed and maintained by the IAEA for over five decades, is a comprehensive database focusing on nuclear power plants worldwide. PRIS contains information on power reactors in operation, under construction, or those being decommissioned.

Radiation Safety Information Management System (RASIMS)

A national infrastructure for radiation safety is essential to protect people from the harmful effects of radiation. IAEA’s Radiation Safety Information Management System (RASIMS) enables Member States to assess how closely their infrastructures for radiation safety are aligned with IAEA Safety Standards’ recommendations and requirements.

Radioactive Waste Operations Benchmarking System

The WWER Radioactive Waste Operations Benchmarking System (WWER BMS) establishes industry-wide standards and guidelines for waste minimization, including source reduction, reuse, and volume reduction.

Reference Input Parameter Library

RIPL-3 is devoted to input parameters needed in calculations of nuclear reactions and nuclear data evaluations. 

Calibration of reference standards used for dosimetry measurements

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.

Research Network of Marine-Coastal Stressors in Latin America and the Caribbean (REMARCO)

The Research Network of Marine-Coastal Stressors in Latin America and the Caribbean (REMARCO) was created in 2018 with the support of IAEA technical cooperation projects. The network provides a unique space for the Latin America and Caribbean experts and institutions to share experiences, capabilities, information, protocols, and common practices addressing vulnerabilities of marine-coastal ecosystems such as chemical and microplastic pollution, harmful algal blooms, eutrophication, ocean acidification and challenges like assessing blue carbon inventories, among others.

Research Reactor Database (RRDB)

The IAEA's Research Reactor Database (RRDB) is an authoritative database containing technical information on over 800 research reactors, including critical and sub-critical assemblies in 67 countries.
