Climate change brings threat of sea level rise to nuclear power facilities

Nuclear power’s dark future Japan Times, 25 Nov 14  BY BRAHMA CHELLANEY “…….New nuclear plants in most countries are located in coastal regions so that these water-guzzling facilities can largely draw on seawater for their operations and not bring freshwater resources under strain.

But coastal areas are often not only heavily populated but also constitute prime real estate. Moreover, the projected greater frequency of natural disasters like storms, hurricanes, and tsunamis due to climate change, along with the rise of ocean levels, makes seaside reactors particularly vulnerable.

The risks that seaside reactors face from global-warming-induced natural disasters became evident more than six years before Fukushima, when the 2004 Indian Ocean tsunami inundated the Madras Atomic Power Station. But the reactor core could be kept in a safe shutdown mode because the electrical systems had been installed on higher ground than the plant level.

In 1992, Hurricane Andrew caused significant damage at the Turkey Point nuclear power plant in Florida, but fortunately not to any critical system. And in a 2012 incident, an alert was declared at the New Jersey Oyster Creek nuclear power plant — the oldest operating commercial reactor in the U.S. — after water rose in its water intake structure during Hurricane Sandy, potentially affecting the pumps that circulate cooling water through the plant.

All of Britain’s nuclear power plants are located along the coast, and a government assessment has identified as many as 12 of the country’s 19 civil nuclear sites as being at risk due to rising sea levels. Several nuclear plants in Britain, as in a number of other countries, are just a few meters above sea level……http://www.japantimes.co.jp/opinion/2014/11/25/commentary/world-commentary/nuclear-powers-dark-future/#.VHYvqNLF8nk
