The issue of 235U enrichment has garnered significant attention among IAEA Member States, leading to dedicated efforts to establish a platform for a comprehensive examination of the current status, prospects, and challenges associated with the utilization of fuels with enrichments exceeding 5% 235U in light water reactors. This publication emerges as the result of two technical meetings, where the outcomes and conclusions regarding the benefits of using high assay low enriched uranium (HALEU) fuel are compiled, while also addressing the safety concerns that arise from its use. It provides a detailed account of technological options and associated issues related to fuel and core design, safety analysis and assessments, manufacturing, handling, transportation, storage, irradiation, and performance in both normal and accident conditions.

The utilization of high assay low enriched uranium (HALEU) fuel in light water reactors has emerged as a topic of significant concern among IAEA Member States. In response to this concern, concerted efforts have been undertaken to provide a platform that facilitates a comprehensive review of the current status, prospects, and challenges associated with the use of fuels with enrichments higher than 5% 235U in light water reactors. This publication represents the culmination of two technical meetings, where the results and conclusions regarding the benefits of employing HALEU fuel are compiled, while also taking into account the safety considerations that arise from its use.

The publication delves into a detailed account of technological options and associated issues related to fuel and core design, safety analysis and assessments, manufacturing, handling, transportation, storage, irradiation, and performance in both normal and accident conditions. It provides a comprehensive overview of the various aspects that need to be considered when utilizing HALEU fuel, ensuring that safety is paramount throughout the entire process.

By undertaking a comprehensive review of the current status, prospects, and challenges associated with the use of fuels with enrichments higher than 5% 235U in light water reactors, this publication aims to contribute to the ongoing efforts of IAEA Member States to ensure the safe and efficient use of nuclear energy. It serves as a valuable resource for policymakers, researchers, and industry professionals alike, as it provides insights into the latest developments and best practices in this field.
