The Department is supporting the UK’s National Nuclear Laboratory (UKNNL)’s work to extract americium from the UK’s civil separated plutonium inventory at Sellafield for the European Space Agency’s (ESA’s) ENDURE Programme.

Discussions are taking place with industry, public bodies and wider government prior to any decision making beyond current commitments.
