In France, the good turned up as a prize (5)
I believe the answer is:
nobel
'a prize' is the definition.
(as in the Nobel Prizes)
'in france the good turned up' is the wordplay.
'in france the' becomes 'le' (French of 'the').
'good' becomes 'bon' (I've seen this in other clues).
'turned up' shows that the letters should be reversed in order.
'le'+'bon'='lebon'
'lebon' in reverse letter order is 'NOBEL'.
'as' is the link.
(Other definitions for nobel that I've seen before include "and 21 Across: Prestigious international award" , "Alfred -, Swedish dynamite inventor" , "Dynamite inventor, Prize founder" , "Prize-endowing Swedish chemist" , "Founder of many prizes" .)
