Consume uranium in energy plant (8)
I believe the answer is:
viburnum
'consume uranium in energy plant' is the definition.
I can't tell whether this defines the answer.
'consume uranium in energy plant' is the wordplay.
'consume' becomes 'burn' (burning is a kind of consuming).
'uranium' becomes 'U' (U is the chemical symbol for uranium).
'in' means one lot of letters goes inside another.
'energy plant' becomes 'vim' (I can't justify this - if you can you should give a lot more credence to this answer).
'burn'+'u'='burnu'
'burnu' inserted within 'vim' is 'VIBURNUM'.
Can you help me to learn more?
(Other definitions for viburnum that I've seen before include "Shrub with small white flowers" , "plant" , "Wayfaring tree with small, white flowers and berry-like fruits" .)
