Sand in storm covers uranium in country (5)
I believe the answer is:
sudan
'country' is the definition.
(Sudan is an example)
'sand in storm covers uranium' is the wordplay.
'in storm' indicates an anagram (I've seen this in other clues).
'covers' means one lot of letters goes inside another.
'uranium' becomes 'U' (U is the chemical symbol for uranium).
'sand' with letters rearranged gives 'sdan'.
'sdan' placed around 'u' is 'SUDAN'.
'in' is the link.
(Other definitions for sudan that I've seen before include "Country divided by the Nile" , "Country W. of Ethiopia" , "Sun ad for the African state" , "Country south of Egypt" , "African nation" .)
