Sellafield's new nuclear lab

Sellafield's reactors and reprocessing bunkers are being decommissioned six decades after the plant began life.

It made plutonium for nuclear weapons and generated electricity for the national grid.

The Nuclear Research Laboratory's Fiona Rayment gives a guided tour of the plant's new research centre.

The lab has been designed to reinvigorate the UK's nuclear industry amid a review of how much electricity should be developed by nuclear power stations.
