How sustainable is nuclear power for the UK?

A University of Manchester research consortium found that UK carbon emissions targets could be met with significant expansion of both renewables and nuclear electricity by 2035. However, this would require a huge increase in nuclear power to make up for the loss of current nuclear stations.
