Lead and uranium atomic team use principally in remote islands (7)
I believe the answer is:
vanuatu
'remote islands' is the definition.
'Vanuatu' can be an answer for 'islands' (island nation). I am not sure about the 'remote' bit.
'lead and uranium atomic team use principally' is the wordplay.
'lead' becomes 'van' (van is the leading part of a movement or group).
'and' says to put letters next to each other.
'principally' says to take the initial letters.
The initial letters of 'uranium atomic team use' is 'uatu'.
'van'+'uatu'='VANUATU'
'in' acts as a link.
Can you help me to learn more?
(Other definitions for vanuatu that I've seen before include "Archipelago, formerly known as New Hebrides" , "South Pacific Ocean nation of 80 islands" , "Southwest Pacific island hit by Cyclone Pam in March" , "Pacific island country, formerly New Hebrides" , "Country of the south-west Pacific" .)
