I would like to thank Rhun and Darren for tabling this important debate today, and to thank Neil for his efforts to ensure the sediment being dumped poses no risk to human health or our environment. The Hinkley waste may be being dumped in Neil's region, but it also affects my region, home to some of the world's top beaches and a haven for marine flora and fauna. For several weeks now I've been inundated with e-mails regarding this.

I know that according to the licence holder, the sediment from the nuclear power station has been tested and deemed to be no threat to humans, and is not classed as radioactive under UK law. However, there are concerns that the testing methodology was not sufficiently robust. The testing methodology only looked at the top 1 m of sediment, and only looked at gamma particles. [Interruption.] Can I finish first, Jenny, and then I will, if I'm within time?

Research conducted elsewhere shows that higher concentrations of radionuclides are found at depths greater than 1 m. We also know that there are 16 times more radionuclides produced by nuclear reactors than were tested for. The sediment surveys tested for caesium-137, cobalt-60 and americium-241, but what about plutonium or curium? Why were these not tested for? What about strontium or tritium? Do these radionuclides not carry a risk to human health? Of course they do, but they were not tested for, nor were the other 50 radionuclides known to be present in discharge from these old nuclear power plants.

As Neil McEvoy's amendment highlights, there were incidents in the 1960s that saw radioactive discharges into the cooling ponds at the Hinkley plant, and several independent researchers believe that harmful radionuclides are contained deep within the sediment.

I understand that the Welsh Government is convinced of the safety of this material, and that it is sincere. However, a large number of Welsh residents are not convinced, and we owe it to them to prove beyond a shadow of a doubt that this material is safe before dumping it on our coastline. Until there is a thorough, scientifically robust, independent safety inspection conducted on this sediment, the licence should be suspended.

If the report categorically deems the sediment to be safe to humans, wildlife and the environment then, by all means, grant the licence. But, until then, we risk doing untold damage to our ecosystem and threaten the viability of some of the world’s top beaches, like Rhossilli and Three Cliffs bay.

The Welsh Government has to put Wales first and insist that more robust testing is carried out, and I urge Members to support the motion and support amendments for the people of Wales. Thank you.
