Production of improved/recommended decay data files of direct application in nuclear facilities, waste management, and for various design teams.
The impact of the CRP is measured by the fact that recommended data it produced are still widely used by the user community in IAEA MS. The updated nuclear decay data parameters produced by this CRP were adopted by the Decay Data Evaluation Project (DDEP) which is the main source of decay data for radionuclide metrology applications worldwide. The data are also disseminated through the DDEP webpage.
Feedback received from the user community confirms that the CRP products are being used and have an impact on the applications.
The nuclear decay data of the minor and major actinides and their decay products that were produced by the CRP are among the most important decay parameters for applications spanning reactor operation, waste management, safeguards/nonproliferation, as well as non-energy applications. The data were included in the compilation of nuclear data for Safeguards that was produced by the Nuclear Data Section upon request from the IAEA Safeguards Department, and as mentioned above, they were adopted by the International Committee for Radionuclide Metrology through the DDEP website. The work has been published in peer-reviewed scientific journals and presented in international conferences. The CRP was therefore of the highest relevance to the Agency’s MP-1 and MP-2 programmatic activities.

Description
High quality decay data are an essential input across a wide range of nuclear applications, and none more so than in the case of the actinides and their related decay chain data. Well defined nuclear data are essential to ensure safe procedures within mining operations, various nuclear fuel cycles for energy generation, environmental monitoring, specific analytical techniques, and diagnostic and radiotherapeutic treatments in nuclear medicine. A major objective of the IAEA nuclear data programme is to promote improvements in the accuracy and quality of nuclear data used in science and technology. The contents of this report constitute the results of a coordinated research project established to assemble an updated decay data library for actinides. Recommended half-lives and decay scheme data have been comprehensively evaluated, and are tabulated in terms of a carefully selected set of actinide radionuclides.
