Nuclear power plants use uranium to operate, whose extraction from mining and enrichment to make fuel for power plants, has a devastating impact on the environment.
This is clearly explained by engineers and Sergio Zabot Monguzzi Carlo, in their recent book "Nuclear Illusion" (ed. Melampus).
As in all mines, the main extraction techniques involve the excavation in the open air or in tunnels. The ore is extracted by drilling the rock or exploding dynamite. Although workers spend more time in booths, in order to limit exposure to radiation, radioactive dust contaminate the surrounding area and the excavations are carried by winds.
If the uranium is too deep tunnels are excavated and the ore is subjected to a time-consuming chemical process, it exposes workers to very high levels of radiation.
mines where instead of using the technique Leaching is pumped into the soil solution of sulfuric acid, with a devastating result for the aquifers, and contaminated by radiation!
During the uranium enrichment increases the concentration of the fissile material for a sufficient amount of neutrons the triggering of the nuclear reaction.
The process of uranium enrichment is difficult and needs a high energy consumption, also produces huge amounts of depleted uranium.
The land is rich in uranium, already now the uranium extracted from existing mines is not sufficient to meet the demand, and use military stockpiles accumulated during the Cold War.
With the construction of new reactors, the uranium price will rise, we will search for new mines, devastating new territories.
In short, the last few decades of uranium mining and uranium prices will always be higher.
The environmental impact is considerable because Uranium processing produces a significant amount of CO2 emissions. Another downside is the large amount of water used in the production of uranium and the need to work with tons of sulfuric acid.
At this point, the opening towards renewable sources, the ' clean energy , remains a dutiful reference point.
The photovoltaic lends itself to the protagonist. Thanks to Account energy new photovoltaic installations are on the rise, technology improves and prices drop.
Even across the ocean, in America, there is a clear trend towards renewable energy, towards what has been called " green economy." The future is in clean and renewable energy: photovoltaics!
Contribute yourself to a healthier environment as well as to have a secure economic and energy savings: photovoltaic system installed!
