asked the Minister of Transport what measures he is taking to ensure the re-routing in transit of nuclear waste from London and other densely populated areas.

Irradiated nuclear fuel is transported under conditions which make it safe for routeing on a normal operational basis. The British Railways Board is responsible for routeing and I am satisfied that there is no reason on safety grounds to re-route the fuel flasks. I understand that the board keeps the question of routeing under review and may vary routes on operational or security grounds from time to time.
