SPRIng ProjectSustainability Assessment of Nuclear Power: An
Integrated Approach (SPRIng)
A multi-criteria decision-support methodology for sustainability assessment of energy options;
Sustainability assessments of the nuclear option within an energy mix scenarios; and
Engagement with and communication of the results of research to relevant stakeholders.

In summary…
Examined the life cycle environmental impacts of all technologies within the current UK electricity mixFossil fuels are the main contributors to most impact
categoriesNuclear has a minor contribution to most impacts
IssuesReliability of existing data / assumptions within dataRelevance to the UKAvailability of data for future technologies
springspring
Next steps…
Access reliable life cycle dataUse of primary data from industry
Model the impacts of future technologies / electricity mix scenarios as defined by SPRIngNext generation reactorsCHPCSP
