Point C power station 'will be built to withstand flood surges'
safety features are to be installed at Hinkley Point C to help
protect it from storm surges and even withstand the impact of
an aeroplane crash.
working on the new power station near Burnham-On-Sea have designed
the new measures following the nuclear disaster in Fukushima,
Japan, that was triggered by a tsunami.
of the upgrades emerged in national media reports over the weekend.
Among the major changes to be made is the installation of a 66
million gallon water tank to flood and cool the nuclear reactors
in an emergency.
is aimed at averting the kind of uncontrolled meltdown that occurred
at Fukushima when pumps used to cool the reactors failed.
Point C will also be the first nuclear power station in the country
to have an outer shell designed to withstand a large plane crash,
the Sunday Telegraph reports.
defence walls are also to be built higher around the diesel motors
that drive the cooling pumps while the motors themselves will
also be bigger.
have also been conducting surveys deep underground to ensure the
foundations cannot be undermined by any kind of storm surge.
Cann, site construction director for the £16 billion power
station, said: "Fukushima was a great tragedy, but something
we needed to pay attention to. They completely got the height
of their sea protection wrong and they didnt have enough
strength and depth around their electricity supplies."
have done some in depth analysis to make sure we have that right.
We made some changes to the design. We have made the diesel engines
bigger and we have included a huge reservoir where we have a static
water supply that we can use to cool the fuel."
plans to build Hinkley Point C were approved by the Government
in October after years of delays over the future of nuclear power
in Britain. However, the European Commission is conducting an
inquiry into whether the deal breaches EU state aid rules and
may have to be revised. This may introduce further delays.
decision to approve the new power station contrasts with the opposition
to nuclear in places like Germany where nuclear has been abandoned
over safety fears following the Fukushima Daiichi accident after
the tsunami in 2011.
tidal wave knocked out the diesel pumps that sent sea water around
Fukushimas reactors to keep them cool, causing them to overheat
and risking a meltdown that saw radioactive gas vented into the
response, engineers have redesigned their plans for Hinkley Point
C to connect a huge standing tank of water to the reactors that
can flood them should a similar accident happen there.
complete, Hinkley Point C will be the first nuclear power station
to be built since 1995 and the biggest in the UK capable
of powering seven million homes. Its four reactors will each drive
a 1.6 GW generator, which together will account for seven per
cent of Britains electricity supply.
