The National Nuclear User Facility (NNUF) is part of the HM Government’s Nuclear Industrial Strategy announced in 2013. The aim of the NNUF is to provide greater accessibility to world leading technologies as a collaborative effort from four complimentary hubs within the UK: the Central Laboratory of the National Nuclear Laboratory (NNL), the Culham Centre for Fusion Energy (CCFE), the Dalton Cumbrian Facility (part of The University of Manchester) and the University of Lancaster.

The National Nuclear User Facility (NNUF) was launched when HM Government’s announced its Nuclear Industrial Strategy in 2013. The aim of the NNUF is to provide the UK nuclear R&D community with better research facilities. The initial investment, £15M from the EPSRC, was in three complementary facilities at: the Central Laboratory of the National Nuclear Laboratory (NNL), the Culham Centre for Fusion Energy (CCFE), and the Dalton Cumbrian Facility (part of The University of Manchester). This investment has enabled the NNUF to provide equipment for experiments on materials that are too radioactive for university laboratories.

Subsequently, a further £1M has been invested in nuclear instrumentation at the Universities of Lancaster and Liverpool, and at CCFE.

These NNUF facilities are available for use by the whole UK nuclear energy R&D community. The NNUF is being developed by a steering committee with representatives from several universities, CCFE, DCF and NNL. One of its roles, in consultation with the R&D community, is to develop proposals for further investments, for research application across the full nuclear energy full nuclear lifecycle
