Production of improved/recommended decay data files of direct application in nuclear facilities, waste management, and for various design teams.
Timely updating of the recommended nuclear parameters to take consideration of a series of decay measurements induced by a previous CRP that had closed in 1986.
Impact
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.
Relevance
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.
