Abstract
Effort has been expended to assess the relative merits of undertaking further decay-data measurements of the main fission-product contributors to the decay heat of neutron-irradiated fissionable fuel and related actinides by means of Total Absorption Gamma-ray Spectroscopy (TAGS - sometimes abbreviated to TAS) and Discrete Gamma-ray Spectroscopy (DGS). This review has been carried out following similar work performed under the auspices of OECD/WPEC-Subgroup 25 (2005–2007) and the International Atomic Energy Agency (2009, 2014), and various highly relevant TAGS measurements completed as a consequence of such assessments. We present our recommendations for new decay-data evaluations, along with possible requirements for total absorption and discrete high-resolution gamma-ray spectroscopy studies that cover approximately 120 fission products and various isomeric states.

The content and preparation of this paper involved both the work and support of various individuals and their institutions. Our sincere thanks are extended to all colleagues who have contributed to this IAEA technical project since April 2005 when these studies were initially conceived and undertaken over a two-year period until mid-2007 as an OECD/NEA Working Party on International Evaluation Co-operation of the NEA Nuclear Science Committee. Furthermore, the IAEA is grateful to all participant laboratories for their assistance in this work since January 2009, and their support of individual staff to attend subsequent working meetings and perform related analytical and experimental activities. Futoshi Minato from the Japan Atomic Energy Agency is also gratefully acknowledged for providing decay-heat calculations for the sixteen fission systems studied herein, based on the recently released JENDL-5 libraries. Work described in this paper would not have been possible without IAEA Member State contributions. Studies at ANL were supported by the US Department of Energy, Office of Science, Office of Nuclear Physics, under contract no. DE-AC02-06CH11357 and by the National Nuclear Security Administration, Office of Defense Nuclear Nonproliferation R &D (NA-22). Work at ORNL was partially supported by the Office of Nuclear Physics, US Department of Energy under Contract No. DE-AC05-00OR22725 and by the DOE Nuclear Data Program, within the FOA 18 1903 project. Thanks are also due to all collaborators who made these particular measurements possible - colleagues at HRIBF-ORNL (D.W. Stracener) and ANL (G. Savard, D. Santiago-Gonzales, J.
