Higher sea levels is a serious threat to nuclear power plants: http://www.huffingtonpost.com/2014/05/19/maps-rising-seas-storms-threaten-flood-coastal-nuclear-power-plants_n_5233306.html

During Superstorm Sandy, for example, flooding threatened the water intake systems at the Oyster Creek and Salem nuclear power plants in New Jersey. As a safety precaution, both plants were powered down. But even when a plant is not operating, the spent fuel stored on-site, typically uranium, will continue to emit heat and must be cooled using equipment that relies on the plant's own power. Flooding can cause a loss of power, and in serious conditions it can damage backup generators. Without a cooling system, reactors can overheat and damage the facility to the point of releasing radioactive material.

This is the demonstration that nuclear power is dangerous. Human errors and natural disasters were and are devastating. We can't afford to produce more energy with this source, it's for the good of the people.

Its not just rising sea levels that pose a threat to Nuclear plants. The heat is also a problem for nukes, especially now during the summer. And it will only get worse with global warming!

Too cold, too warm, every change in the climate is dangerous for unstable structures. I hope they won't secure nuclear plants but close them.
