Centre for Radiochemistry Research

Centre for Radiochemistry Research. It is a world-leading academic department dedicated to fundamental and applied research in nuclear and radiochemical science. Operating within the University of Manchester, the Centre builds upon a historic legacy in the field dating back to the work of Ernest Rutherford and Hans Geiger. Its mission encompasses advancing the nuclear fuel cycle, environmental remediation, and pioneering the chemistry of radioactive elements.

History

The origins of radiochemistry at the University of Manchester are deeply intertwined with the pioneering nuclear physics experiments of Ernest Rutherford in the early 20th century. Following the dawn of the Atomic Age, formalized research in radiochemistry expanded significantly. The Centre itself was formally established in 1965, consolidating expertise during a period of rapid growth in the United Kingdom's civil nuclear program. It evolved from the university's long-standing Department of Chemistry, leveraging the region's deep industrial links with facilities like the Sellafield nuclear site. Throughout the late 20th century, the Centre contributed to national priorities, including research related to the Advanced Gas-cooled Reactor and nuclear waste management. Its sustained excellence led to its recognition as a premier hub for actinide and radiochemistry research in Europe.

Research focus

The Centre's research portfolio is strategically aligned with global energy and environmental challenges. A primary focus is the nuclear fuel cycle, encompassing studies on fuel fabrication, the chemistry of used nuclear fuels, and advanced separation techniques like those explored in the EUROACT project. Significant effort is dedicated to the environmental behavior of radionuclides, investigating their migration in ecosystems such as the Sellafield site and developing novel remediation strategies. Fundamental science is centered on the synthesis and characterization of actinide and lanthanide compounds, probing unique bonding and electronic structures. This work supports applications in nuclear medicine, including the development of targeted alpha therapies and novel radiopharmaceuticals. Research also extends to nuclear security and forensics, aiding international safeguards administered by the International Atomic Energy Agency.

Facilities and equipment

The Centre operates specialized, secure laboratories designed for handling radioactive materials across a wide range of activities. These include modern radiochemical fume hoods, gloveboxes, and alpha-tight containment systems for work with transuranic elements. Key analytical instrumentation includes inductively coupled plasma mass spectrometry for ultra-trace analysis and gamma-ray spectroscopy systems utilizing high-purity germanium detectors. For molecular-level characterization, researchers utilize the Harwell Science and Innovation Campus facilities, including the Diamond Light Source synchrotron for X-ray absorption spectroscopy. The Centre also benefits from proximity to the National Nuclear Laboratory and direct collaborations with the Dalton Nuclear Institute, providing access to further specialized nuclear infrastructure and hot cell facilities.

Key personnel and collaborations

The Centre is led by Professor Steve Liddle, an expert in actinide chemistry and a fellow of the Royal Society of Chemistry. The faculty includes renowned researchers such as Professor Francis Livens, whose work focuses on environmental radiochemistry. The Centre maintains a deeply collaborative ethos, partnering extensively with major national bodies like the National Nuclear Laboratory, the Nuclear Decommissioning Authority, and the United Kingdom Atomic Energy Authority. Internationally, it is a key partner in consortia funded by the European Commission and the Engineering and Physical Sciences Research Council. Strong industrial links exist with companies such as Sellafield Ltd, Jacobs Engineering Group, and Westinghouse Electric Company. These partnerships ensure the translation of fundamental research into practical solutions for the global nuclear industry.

Notable achievements and impact

Researchers at the Centre have made seminal contributions to understanding the fundamental chemistry of the actinide series, publishing high-impact studies in journals like *Nature Chemistry* and *Angewandte Chemie*. Their work on the interaction of radionuclides with mineral surfaces has directly informed safety case models for geological disposal facilities, influencing policy for organizations like Radioactive Waste Management Limited. The Centre played a pivotal role in the EU ACTINET network, integrating European actinide research. Its development of novel chelating agents for plutonium decorporation has advanced medical countermeasures for radiation exposure. Furthermore, the Centre's alumni hold influential positions worldwide in academia, national laboratories such as Los Alamos National Laboratory, and regulatory agencies, cementing its role in educating the next generation of leaders in nuclear science.
