New creator of atomic energy (7)
I believe the answer is:
reactor
'atomic energy' is the definition.
Although both the answer and definition are singular nouns, I cannot see how one could define the other.
'new creator' is the wordplay.
'new' is an anagram indicator.
'creator' with letters rearranged gives 'REACTOR'.
'of' is the link.
Can you help me to learn more?
(Other definitions for reactor that I've seen before include "one liable to have a meltdown if things go disastrously?" , "Producer of nuclear energy" , "nuclear facility" , "Nuclear power source" , "source of power, perhaps" .)
