What is Nuclear Waste?
What is Nuclear Waste?
8th February 2022
One of the most common concerns about nuclear energy relates to waste management. This webinar brought together international experts to explain what nuclear waste actually is, how it's managed, recycling technologies, and the realities of long-term storage solutions.
Expert Speakers
Marion Poupinel-Descambres
Strategy Director, Orano Recycling Business Unit
Marion leads strategy for Orano's recycling operations. Orano is an international nuclear fuel cycle company that manages France's nuclear waste and recycles spent nuclear fuel. France recycles approximately 96% of its spent fuel, extracting usable uranium and plutonium for reuse in reactors. Marion brings practical expertise in industrial-scale waste management and the circular nuclear fuel cycle.
Dr. Paul Cosgrove
Research Associate, University of Cambridge
Paul is a research associate at the University of Cambridge working on the physics of nuclear reactors. He lectures on the Nuclear Energy MPhil program and his research interests include computational methods and fast reactor physics. Fast reactors have the potential to consume long-lived waste from conventional reactors, dramatically reducing storage timeframes.
Discussion Topics
- Types of Nuclear Waste: Low-level, intermediate, and high-level waste classifications and volumes
- Spent Fuel Recycling: How France and other countries reprocess used fuel to extract valuable materials
- Volume & Comparisons: Actual quantities of waste produced per person over a lifetime of nuclear electricity
- Storage Solutions: Dry cask storage, deep geological repositories, and safety timeframes
- Fast Reactors: Advanced reactor designs that can consume long-lived actinides
- International Best Practice: Learning from France, Finland, Sweden, and other countries with comprehensive waste strategies

Nuclear waste management is a solved technical problem, with multiple proven approaches used successfully around the world. The total volume of high-level waste is remarkably small compared to other energy sources, and modern recycling technologies can extract over 95% of the energy from spent fuel. With advanced reactor designs on the horizon, the "waste" from today's reactors may become valuable fuel for tomorrow's clean energy systems.
