Chernobyl at last due for new reactor component (4,3)

I believe the answer is:

fuel rod

I'm a little stuck... Click here to teach me more about this clue!

'reactor component' is the definition.
I don't know anything about this answer so I cannot judge whether it can be defined by this definition.

'chernobyl at last due for new' is the wordplay.
'at last' suggests the final letters.
'new' indicates an anagram.
The final letter of 'chernobyl' is 'l'.
'l'+'due'+'for'='lduefor'
'lduefor' with letters rearranged gives 'FUEL ROD'.

Can you help me to learn more?

I've seen this clue in The Times.
