YOU reported that the UK has stockpiled enough highly toxic plutonium to make more than 16,000 nuclear bombs and that this stockpile is so serious the Government must urgently launch a strategy for its disposal or long-term use (Echo, Sept 22).

What this long-term use is I haven't got a clue. But I am extremely worried that the Billingham salt mines will once again come into the reckoning for the disposal plans.
