Hurricane Sandy and Salem Reactors
Several days ago I wrote a post about the impact of Hurricane Sandy on nuclear reactors on in the East Coast of the United States. With respect to a particular reactor, I wrote:

Dwelling on Fukushima
I have covered different aspect of the Fukushima nuclear disaster in past blog posts. My sister blog http://www.Radiationrelations.com presents four link every day about radioactivity and nuclear issues, often dealing with Fukushima. I thought that I should explain why I dwell on Fukushima so much. Nuclear power is an important source of electric power generation in the world today.
Nuclear Power in the United Kingdom
The first commercial power plant in the United Kingdom and the world went into operation in 1956 at Calder Hill but the main reason for the reactor being built was to produce weapons grade plutonium. and the last plant built in the UK was put into operation in 1995.
Hurricane Sandi and East Coast Reactors
I have discussed the fact that nuclear reactors require an enormous amount of water to cool them in previous posts. This means that they have to be located near major sources of water such big rivers, big lakes or the ocean. Since many big cities are near large bodies of water, this makes such locations convenient for major power plants that supply electricity to cities. Unfortunately this also makes the reactors vulnerable to flooding.
Finland depends on nuclear power
Seventy percent of Finland’s power comes from coal, gas, hydro and biofuels. Some power is imported from Russia. Coal is imported from Poland and Russia. All imported gas comes from Russia. Finland has four operating nuclear reactors that supply about thirty percent of their electrical power. When the annual rainfall is low, there is a power shortfall and more electricity must be imported. Finland is working to be more energy independent.
Nulcear Fuel Monitors Powered by Heat of Nuclear Fission
The Fukushima nuclear disaster was partly caused by the tsunami triggered by the nearby earthquake. The generator room that supplied power for monitoring and cooling was located in a basement which flooded. Without monitoring and cooling , several of the reactors overheated and generated gases which exploded causing major damage to the reactor buildings.
