The Problem with Nuclear Power

Nuclear power cannot solve global warming:

Once seen as the solution to global climate change, nuclear power is far from it. Everywhere along the nuclear chain - from the mining of uranium to its transportation to the construction of the power plant - greenhouse gases are emitted.
Furthermore, their construction takes too long to solve global warming. In fact, investing in nuclear power deprives other efforts - such as energy efficiency, conservation and renewable energy - of further funding and development.

Nuclear plants release radiation:
The levels of radiation released in the air, water and soil are considered "safe".  However, this standard is based on how it impacts healthy, white males and does not take consideration for children that are sensitive to cancer-causing radiation.
They create harmful radioactive waste:
From mining to milling, processing to enrichment, fuel fabrication to fuel irradiation in reactors, large amounts of harmful, long-lasting radioactive waste is produced. In addition to 20-30 tons of high-level radioactive waste per reactor per year, this includes so-called "low" level radioactive waste.
The current solution for the "disposal" or "storage" of this waste is unacceptable. There is no scientifically safe place to dump this waste, and new reactors would exacerbate the problem. Additional "low" level radioactive waste would have to be dumped in landfills or incinerated, polluting the water and air.
Nuclear plants are too costly:
At $6 to $12 billion each, nuclear reactors are not a cheap solution. Nuclear power has already been subsidized hundreds of billions of dollars. Why should we, the taxpayers, subsidize the electric utility companies' investments any longer?
Development of nuclear technology brings war and terrorism:
This has been seen at the September 2007 bombing of Syria's suspected nuclear site by Israel, and the controversy over Iran's nuclear program. Reactors will always set the stage for atomic weapons production. So, as long as power plants exist, there will always be tension over the possibility of a nuclear attack. Furthermore, reactors are soft targets for terrorists to get hold of nuclear materials, so the more reactors built, the greater the risk.
Any accident will be catastrophic:
All nuclear plants are vulnerable to accidents or attacks. Nevertheless, if an accident did occur, the current evacuation plans are completely unrealistic. In addition, the Price-Anderson Act ensures the utility's liability of an accident is limited to only $10.8 billion. This is absurd, considering a serious reactor accident could cause as much as $600 billion of damage. Once again, the balance would likely have to be paid by us, the taxpayers.
There are better alternatives:
What bothers us most is we already have better, cleaner, safer and cheaper alternatives available and ready to implement. Perhaps with the recent election of our new US government, nuclear energy will be put to rest and renewable energy will be harnessed on a larger scale.
But while we wait, it is possible to start harnessing renewable energy at home.  What's more is, it does not cost very much and is rather simple to implement.  Various solar and wind power guides have already become available, which you can see in our reviews section.

Reactor Nuclear works

How the Reactor Nuclear Works

By : R.Sinuhaji

Since 1950s design and developed of power station is began. Many developed of reactor nuclear as a power station using by this design.Until the older reactors end of their working life, a new designs are being introduced.

There are a two types of nuclear reactors generated for nuclear electricity , imagine that.Splitting the atoms of certain elements and controlling the release of this energy  is the way of a nuclear reactors works.Gas or water heat with high temperature is used to make steam this is produced from that energy.Like a fossil fuel power station the steam is then used to drive turbins.The steam is used to drive a turbin which propels the submarine, these are implemented on a nuclear submarine.The neutrons are used in a research reactor.
All of the reactors operated by different way, such as fast neutron reactor, boiling water reactor, pressurised water reactor, and gas cooled reactor, but there are still a same components could found in all of that reactors such as :

Containment : The containment is usually a meter thick steel structure and concrete. The containment function is to protect from the radiation if there be an accident or incident overcome the radiation effect in the outside world, this is kind of structure design protector for the reactor core.Fuel  : Placed into fuel assemblies in the reactor core arranged from fuel rods which is arranged in tubes, using Uranium Oxide ( U02 ) .

Moderator : Heavy water or even graphite,usually water as a moderator, the function is to make it the neutron become a slow down released from fission, that’s why more fission.

Control Rods :  Used to control the rate at which the reaction occurs, they are inserted or retaken from the core of the reactor. Material such as hafniumor boron and cadmium is a made for neutron absorbing material.

Coolant : To transfer heat away from the core using a gas coolant or a liquid

Pressure Vessels or pressure tubes :This is hold the fuel and transport the coolant through the moderator, the pressure vessels is contains a series of tubes. Reactor core  and moderator and coolant contain usually steel vessels.

Steam Generator : To make steam to drive turbine from the heat of the reactor , some of the part of the cooling system is steam generatos.

Nuclear plants can be decontaminated and decommissioned or can be safety  with processed from treated to the nuclear waste it is also can be recycled.
