U (7)

Ross

I believe the answer is:

uranium

'u' is the definition.
(synonyms)

This is all the clue.

(Other definitions for uranium that I've seen before include "Source of power" , "Radioactive element used for nuclear energy" , "Fissile element" , "Mineral used in nuclear reactors" , "Chemical element used to get nuclear energy" .)

I've seen this clue in The Guardian.
