I agree with those campaigning against the dumping of ‘nuclear mud’ off the cost of Wales that we should not allow Wales to become a dumping ground for waste created by others.  There’s some question over the extent to which the waste is, in fact, radioactive, but whether it is or isn’t is irrelevant to the question of whether we should be accepting it or not.
We need to be wary, though, of double-edged swords.  If the starting point is that a country or territory creating toxic (including nuclear) waste needs to find its own method of disposal within its own territory, then it follows that anyone supporting the construction of a facility likely to create such waste must be willing to retain and dispose of the waste created once that facility is completed and operational.  Assuming that the waste is a problem for ‘somebody else’ to resolve is simply hypocrisy.
In Wales, and in the case of nuclear waste, this is a particular problem for Plaid.  Whilst some members of the party are actively campaigning against the dumping of mud from Hinkley off the coast of Wales, others are openly arguing for the construction of new nuclear power stations in Wylfa and Trawsfynydd, without ever seeming to say anything about what happens to the radioactive waste which will be produced.  But if it is wrong for England to dispose of its problem in Welsh waters, it is surely equally wrong for Wales to assume that the waste arising from any new nuclear power stations in Wales can simply be exported – whether to England or to anywhere else.
Those who support the construction of new stations – and I include in that category those who try to argue that extra facilities built on new sites are somehow not ‘new’ at all – need to be prepared to explain to people how and where they intend to dispose of the waste.  Anything else is just dishonest.
