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.

Reference Input Parameter Library

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

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.

Pointwise Data

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

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.

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).

Nuclear Wallet Cards

Nuclear Wallet Cards present properties for ground and isomeric states of all known nuclides. 

Nuclear Science References

The NSR is a bibliography of nuclear physics articles, spanning nearly 100 years of research and indexed according to content.

Nuclear Safety Action Plan Platform

This Platform provides a mechanism to enhance the transparency of activities associated with implementing the IAEA Action Plan on Nuclear Safety and to improve the dissemination of safety-related technical and technological information among IAEA Member States for the purpose of enhancing nuclear safety worldwide.

Nuclear Instrumentation Portal

The Portal gives access to its community of users on a wide variety of nuclear science and instrumentation topics.

Nuclear Events Web-based System

The Nuclear Events Web-based System (NEWS) is an IAEA-supported online communication channel that is linked to INES, the International Nuclear and Radiological Event Scale, which rates nuclear and radiological events according to their safety significance.

Nuclear Data for Safeguards

This data collection contains selected nuclear data for actinides and fission products as well as fission product yields for safeguards applications.

NuDat 2

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