Preparing for Low Enriched Uranium (LEU) in Canada's Nuclear Future

Abstract

To meet the net-zero carbon emission targets by 2050 while ensuring energy security, Canada is projecting the need for increased nuclear capacity, including large nuclear power plants and Small Modular Reactors (SMRs). This paper aims to inform the Canadian nuclear community of the imminent changes and associated responsibilities to ensure a safe and regulated addition of new nuclear technologies utilizing Low Enriched Uranium (LEU) fuels (uranium enriched below 20 wt.% uranium-235). This paper outlines the fuel enrichment processes and discusses LEU's global utilization and market trends. Regulatory requirements, safety, security and safeguards of LEU fuels are addressed including transportation considerations. Interim storage solutions and long-term disposal strategies are also described at high-level. A fact sheet on LEU is included, which summaries the key points communicated in this paper.
