Thus US agency removed uranium from blue cordial (8)
I believe the answer is:
'blue cordial' is the definition.
'sociable' can be an answer for 'cordial' (thesaurus). I am not sure about the 'blue' bit.
'thus us agency removed uranium' is the wordplay.
'thus' becomes 'so' (synonyms).
'us agency' becomes 'cia' (I've seen this before).
'removed uranium' becomes 'ble' (I can't justify this - if you can you should give a lot more credence to this answer).
'from' acts as a link.
Can you help me to learn more?
(Other definitions for sociable that I've seen before include "Marked by friendliness" , "Friendly - gregarious" , "Easy in company" , "Fond of others' company" , "Friendly and pleasant" .)
