EDF unveils fresh details on new fish deterrent technology to be used at Hinkley Point C

 An alternative acoustic fish deterrent (AFD) system is being proposed for
the Hinkley Point C nuclear power station near Burnham-On-Sea to end a
bitter row over some of the site’s environmental measures.

The move sees EDF, which owns the nuclear power site, drop the controversial idea to
create new salt marshes along the Severn Estuary rather than fit AFDs to
the station’s water intake turbines. The company had been applying to the
Environment Agency for permission to not fit AFDs due to the high cost and
the danger for divers involved in fitting them in the fast-flowing tides
and poor visibility of the Bristol Channel.

Now, Hinkley C stakeholder relations head Andrew Cockcroft has said an innovative new form of AFD could be used. Mr Cockcroft said it was EDF’s preferred solution to the
issue of deterring fish from swimming too close to the Hinkley intakes and
being sucked in. He told Burnham-On-Sea.com: “The technology, pioneered
in the South West, is proven and deployed internationally.” “We are now
working with experts to provide the scientific data to underpin the case
for using it at Hinkley Point C.”

“We have received positive feedback
from environmental groups and this option is now our preferred solution
rather pursuing salt marsh creation.” Andrew Cockcroft adds that all salt
marsh design and development would be paused while work continues in 2025
to prove the effectiveness of the new AFD system. The new AFDs are already
used in fishing fleets around the world, with the technology using
electronic transducers to target specific fish species with high-frequency
sound.
