"Hinkley Point, Least "Suitable" Site for Britain's First New Nuclear Reactor in Years?"

"Can any such facility at Hinkley Point ever be considered seismically safe?" Quotes from.."What's that Coming Over the Hill?" 16/06/12, also see "The Threat from Tsunamis...." 29/02/12 on this blog. 

Quote: "Ask yourselves how it has come to be acceptable for, for instance; The Russian and American presidents (ostensibly -and in reality- gnashing their teeth over Poland) to cabal themselves during the recent summit in Tokyo and get their heads together on how both to repair the Kashiwazaki-Kariwa reactor (  http://www.stwr.org/land-energy-water/nuclear-power-no-panacea-critics-say.html http://en.wikipedia.org/wiki/Mihama_Nuclear_Power_Plant http://www.greenpeace.org/international/en/news/features/earthquake-fire-and-nuclear-l/ -Edited 11/12/10-), and keep the whole affair from the public?"


""Recently, an earthquake occurred along the English Channel
coast, with its epicentre at Folkestone in Kent, at
8.28 a.m. (local time) on 28 April 2007. The local earthquake
magnitude was estimated by the British Geological Survey
as 4.2ML (Walker and Musson, 2007) and no discernible
affect was reported on the sea. However, worryingly, a local
news outlet reported that coastal residents on feeling the
tremor “started rushing out from their houses and on to the
beach for safety” (Kent News, 2007)! This highlights the
need to assess the threat from tsunami and associated hazards
in Britain and, if appropriate, raise public awareness of
the potential hazards."

According to "The Natural Hazards and Earth System Sciences" organisation (go to.... http://www.nat-hazards-earth-syst-sci.net/8/587/2008/nhess-8-587-2008.pdf ) seismic events either in or on either side of The Channel are historically far from rare!

"..a 2005 BBC2 Timewatch documentary which was postponed and re-edited after the Asian tsunami due to its sudden topicality. It documented how, out of a clear blue sky on 30th January 1607, nearly 600 km of the Devon, Somerset and Welsh coast was inundated by a wave of up to 7.5m (25ft). The ‘largest and most destructive flood in British history’ , it may have been caused by a tsunami deriving from an undersea quake, the wave reaching up to 14 miles inland (to the foot of Glastonbury Tor), leaving a temporary inland sea of over 200 square miles for ten days, and drowning around 2,000. For the benefit of sceptics, the academic study the documentary was based on pointed out a 1755 seaquake off Portugal had sent out a 15m (49ft) high tsunami that killed nearly 50,000. There has also been a claim a tsunami hit Dorset in 1868 – luckily the relatively deserted stretch of shore west of Portland."

..I watched the "Timewatch" documentary when it was screened, the evidence for the tsunami it dealt with seemed very strong as too did that of they're estimation for the event's source (the point where the European continental shelf ends some considerable miles S.W of Ireland in the N.Atlantic).

"The Great Flood
The great flood was seen by some at the time
as a judgement from God on his people. It is
generally considered to have been the result
of an exceptionally high tide coupled with a
storm surge, rather than the more modern
tsunami theory. Flood prevention from a Severn barrage in this
instance would be direct, in the manner of the Thames Barrier. The
conditions for such a storm surge to occur again
are possible though of low probability..........
...A barrage could hold water out of the upstream river systems at high
tide, meaning that if there were some hours warning of flash floods, as
was the case in summer 2007, generation would cease and the
barrage sealed at the first available low water. At Gloucester this
would make a 2 metre difference to water levels on a spring tide, on a
neap tide this would mean no reduction in water levels, though still a
four metre difference further downstream at Sharpness (Berkeley
Magnox nuclear facility), close to vulnerable areas of the A38 and M5

(Underline mine; I had a pdf file map of Britain showing the various nuclear facilities which I have, unfortunately, been unable to find again having lost the file owing to a PC crash. There were two facilities detailed at the very mouth of The Severn itself on either side of the estuary. It struck me at the time that any tsunamic event which might hit the area would strike these sites with tremendous force and almost certainly distribute radioactive contaminant all over the already devastated region.)"
