Diolch, Llywydd. If I were told to make up a story, I don't think I could make up something as unbelievable as this. The UK and Chinese Governments strike a deal with tens of billions of pounds, and as part of the deal they plan to dump 320,000 tonnes of mud from outside a nuclear power station off the coast of Wales without testing it properly. 

Many of us campaigned for years for this institution, because at times like this, we expected a Welsh Government to stand up for us. But what has Labour done? Want to dump your waste on us? No problem, fine. They've welcomed it. Let's for the moment forget about the potential health concerns and the lack of an environmental impact assessment. Why would you accept 320,000 tonnes of waste being dumped on your doorstep by your neighbour? Why would you do that?

On 20 June this year, Emeritus Professor Keith Barnham, Imperial College London, wrote to the Government to warn about the possible dangers with the mud from outside of Hinkley Point. Magnox Ltd have admitted there were cooling pond accidents in the 1960s with weapon-grade plutonium. This was new information and should have forced a rethink on the licence. In terms of safety, the Government has accepted the bare minimum. Every physicist I've spoken to says that in order to identify every kind of plutonium that you may find in such mud, there needs to be done three kinds of testing: alpha spectrometry, mass spectrometry and gamma spectrometry. This is just scientific fact—speak to the physicists—and it's being reckless to ignore this. Irresponsible. With respect, Cabinet Secretary, you don't know what you are doing.

We've had excuse after excuse that nothing can be done, that it's all the fault of Natural Resources Wales. In Wales, we have the only Government in the world that is unable to control the very agencies it has set up, and once again, through legal action by the campaigners, we've found out that it's not Natural Resources Wales who was ultimately responsible, but the Cabinet Secretary. The monumental incompetence and arrogance is staggering, and I say to every single Labour Member here today: people voted for you and they put their trust in you. Listen to them. Listen to your voters, and not the whip.

It was also established through legal action that there was no environmental impact assessment carried out for the dumping on the Cardiff Grounds and its aftermath. There was a 2,000-page document about the effect on the Bristol side, but virtually nothing about Wales. And let's flag up also that the Minister at the time, who decided not to have an environmental impact assessment, was a former lobbyist for the nuclear industry. Extraordinary—only in Wales. Only in Wales.

So, how can you allow the dumping of 320,000 tonnes of mud from outside a nuclear power station and not examine the effects on the local environment? The eyes of the world are on Cardiff today—this is an international campaign—and my amendment asks you to support an environmental impact assessment. Why would you vote against that? Forget the technicalities; let's get the assessment done. 

I'm going to quote Professor Keith Barnham, Imperial College London, now, a former particle physicist—we used to call them nuclear physicists. And he says the tests done on the Hinkley mud were done with gamma radiation detectors. Plutonium nuclei do not decay by emitting gamma rays, but rather by emitting alpha particles, for which the mud has not been tested.

You have a choice now—we all have a choice. This is the National Assembly for Wales. People vote for us to look after Wales, do things in their best interests and hold the Government to account. So, will you stand up for Wales today? Or will you let the nuclear industry dump all over our country?
