Petitions (on the National Assembly website and at sumofus.org) calling on the Welsh Government to suspend a licence to dump 300,000 tonnes of mud from the disused Hinkley Point nuclear stations 1.2 miles off Cardiff Bay have been signed by nearly 60,000.  The dredged material arises from the construction of the new power station and there are fears that dumped radioactive mud will end up on land in South Wales.
