RADioactive waste management and Environmental Remediation
PI: Prof Katherine Morris / Prof Jon Lloyd
The NNUF RADioactive waste management and Environmental Remediation (RADER) user facility will support research into characterising and understanding the behaviour of radioactive species in engineered and natural environments. This science base is crucial for underpinning large parts of the UK’s >100 year, >£130 billion nuclear decommissioning, clean-up and waste management programmes.
To support this work, the RADER user facility will deliver a suite of laboratories designed to handle and analyse radioactive samples from engineered and natural environments. The facility will be co-located with Manchester University’s Research Centre for Radwaste Disposal (RCRD) and embedded within the NERC-funded Williamson Research Centre for Molecular Environmental Science (WRC), drawing on established complementary skills and expertise.
Uniquely in the UK, RADER will offer dedicated laboratories enabling users to undertake Low Level Radiometrics, Environmental Characterisation of Solids (inorganic and biological), Environmental Characterisation of Solutions and Sample Preparation, all in one location and with dedicated Experimental Officer support. Combined, these integrated state-of-the-art facilities will enable low level separations and microbiological, mineralogical and molecular-scale environmental research with a wide range of environmentally relevant radionuclides. RADER will support experiments across realistic radionuclide concentration ranges, and offer comprehensive authentic sample analyses.
Relevant topics for investigation within RADER will include radioactive waste disposal, decontamination, land management, effluent treatment and radionuclide transport in the biosphere, especially where radioactive sample handling and characterisation are required.
The new infrastructure being delivered to the RADER user facility is summarised in key areas below, and augments the already strong infrastructure in the WRC. Support is also provided from 'NNUF @ CRR' on aspects of spectroscopy, magnetism, reprocessing and computational modelling. This will create a suite of RADER laboratories able to handle low-level radiochemical separations and environmental chemistry/biogeochemistry experimental work with radioactive samples. RADER facility development was informed by extensive experience of working with radioactive, environmental samples and devised in close consultation with the UK and international academic and industrial user community.

RADER is open for research in person, or for sample analysis. The suite of new laboratories and all instruments are now fully commissioned. In the first instance please do reach out to the RADER team to discuss any requirements.
As a first step, please email firstname.lastname@example.org and email@example.com to contact RADER for a discussion about the practical feasibility of your proposed research project. Then, you will need to complete a simple NNUF application form. When doing so, please upload an email exchange between you and a member of staff at RADER, confirming the feasibility of your proposed research. Please see the access page of this website for more detail about the NNUF funded user access scheme.
