NNUF-EXACT (National Nuclear Users Facility - Next Generation Accelerated Characterisation Technologies) is based at the University of Southampton and aims to be a world-leading radiochemistry facility enabling research and training in accelerated nuclear characterisation and remediation technologies underpinning civil nuclear programmes, decommissioning and site clean-up and new nuclear infrastructure. Our aim is to provide an easily accessible state-of-the-art test-bed facility and supporting infrastructure for research, technology development / validation and training in in-situ, on-site and off-site characterisation and remediation methods, including for complex / problem waste streams. The laboratory facility provides a flexible space for the development and testing of new methodologies and technologies with low level active reference materials and radiotracers. The laboratory features fume cupboards and bench and floor space with a customisable aqueous test rig to permit active testing of in-line and on-line sensors. The facility contains a portable gamma detector, an automated gamma spectrometer, a benchtop liquid scintillation counter and an SBET analyser as well as access to a vast range of radiometric and non-radiometric instrumentation via the supporting facilities. In addition to the comprehensive training offered to all users of the facility including safe working practices in a radiochemical laboratory and training in characterisation techniques and radiometric instrumentation (including sensor and on-site technologies), a series of training courses and workshops are offered. These courses will be held via e-learning as well as in lecture theatres and classrooms at the University of Southampton’s waterfront campus and delivered by leading industry and academic professionals.
