Civil reactor in more than dangerous state? (12)

Ross

I believe the answer is:

overcritical

'in more than dangerous state?' is the definition.
(critical can mean dangerous or urgent)

'civil reactor' is the wordplay.
'civil reactor' anagrams to 'OVERCRITICAL'.
However, I am not sure how the anagram is indicated.

I've seen this clue in The Guardian.
