A particular threat to health: Why it is vital to stop the dumping of mud from Hinkley Point C in the Severn Estuary.

 Richard Bramhall: A particular threat to health: Why it is vital to stop
the dumping of mud from Hinkley Point C in the Severn Estuary. In 2018 the
French state-owned company Électricité de France (EDF) dug more than
100,000 tonnes of radioactively contaminated mud from the bed of the Severn
near Hinkley Point. Ignoring widespread protests they dumped it back into
the water less than two miles from Cardiff. This was to allow construction
of huge inlets and outlets for water to cool the reactors in the new
nuclear power station – Hinkley Point C – which EDF is building in
Somerset.

EDF held an old licence for the 2018 dump but it expired before
they could shift their target volume of nearly a million tonnes. They
applied to renew the dumping at Cardiff but, because of strong opposition
in Wales and more protective Welsh environment law, they switched to a site
at Portishead near Bristol.

This August the Marine Management Organisation
granted a licence for the Portishead operation and dumping immediately
began again. Campaigners on both sides of the estuary have now applied for
a Judicial Review. The legal challenge identifies many scientific and
regulatory issues.

This article concerns only one:- the health impact of
radioactive particles in the mud. Every nuclear power station in the world
vents dust particles. They are licensed to do this. Filters trap fragments
bigger than about 5 microns (thousandths of a millimetre) but thousands of
billions of smaller particles are released, as data published by the UN
show. Particles this size are inhalable and are biologically very mobile.
The greatest proportion are made of uranium.
