This TECDOC provides guidance on strategy definition for decommissioning graphite moderated nuclear reactors, including the assessment of key external drivers and the identification of the main sequence of activities and associated major tasks. The importance of identifying key interlinkages between major activities is emphasised, such that the broader implications of early phase decisions are well understood. Decisions concerning the long-term management of irradiated graphite are of critical importance. The illustrative strategic roadmap presented in the publication is intended serve as a practical tool to assist the development of the detailed dismantling strategy for both power and research-oriented reactors.
Detection of Unintended or Accidental Medical Exposures in Radiotherapy Through Patient Response
IAEA-TECDOC-2138 ¦ English ¦ 65 pages ¦ Date published: 2026
Unintended and accidental medical exposures have been identified in a variety of ways, including patient responses to radiation. Many such incidents have been reported in the IAEA Safety in Radiation Oncology (SAFRON) voluntary reporting and incident learning system. Failure to recognise such exposures can have significant consequences for patients, including recurrence of disease and life-threatening medical injuries. This TECDOC provides radiotherapy professionals with an overview of case studies in which patient responses to radiotherapy were unexpected, leading to the identification of unintended and accidental medical exposures. It offers guidance to help professionals minimize or prevent such exposures and provides practical solutions for investigating these responses, along with recommendations for determining appropriate actions.

Evaluation of Three Mile Island Unit 1 Fuel Samples: Assemblies NJ05YU and NJ070G (Type 15×15)
NEA/WKP(2026)2 ¦ English ¦ 81 pages ¦ Date published: 2026
This Working Paper contributes to the data evaluation work for the Spent Fuel Isotopic Composition Database (SFCOMPO) ‒ the world’s largest open database of destructive assay data for spent nuclear fuel. The database includes measurement data for over 750 fuel samples selected from fuel irradiated in 44 reactors of 8 types. The database provides descriptions of the measured fuel samples’ characteristics and operation histories and includes datasets of measured nuclide concentrations for over 60 nuclides, key actinides and fission products, which span needs and interests of a variety of nuclear science and engineering applications, including criticality safety, reactor physics, nuclide inventory, nuclear data, decay heat, and radiation shielding. The SFCOMPO database is maintained and developed by the Nuclear Energy Agency (NEA) and managed by the SFCOMPO Technical Review Group (TRG) mandated from the NEA Nuclear Science Committee (NSC) Working Party of Nuclear Criticality Safety (WPNCS). One of the primary missions of the SFCOMPO TRG is to perform peer-review assessment of the datasets in the database and develop high-quality benchmarks and benchmark models based on these data. Destructive assay measurement data are widely recognised as one of the most reliable bases for validating the computational tools and associated nuclear data applied for predicting nuclide inventories in irradiated nuclear fuel.
