With the present type of reactor using enriched uranium fuel, 50 - 100 years probably, but this will mean using lower grade ores. At some point, unless nuclear fusion has come good, it will become economic to use plutonium and perhaps thorium in breeder reactors, and if this technology is successful this could continue for many more years.

over 9000 days

A2. 9000 seems excessive, even 10 years is only 3650 days. Many plants experience delays in building due to the design not being fully settled before starting to build, leading to extra safety requirements or control changes. I would think about 6 years is more normal, but could be up to 10 years.

Once you have enough nuclear fuel, usually uranium enriched with U235, and have built the power plant, it doesn't cost anything to actually produce the nuclear reaction to start the reactor up. Obviously you have replacement fuel to purchase but this will be after several years.

The enrichment process used to be carried out by gaseous diffusion which used a lot of energy, but is now done with centrifuges which is more economical. Then the energy input to make all the plant and equipment, and assemble it on site, is considerable, but to put a figure to it would be quite a task.

Nuclear energy in a reactor starts as soon as it has reached criticality, there is no delay in the nuclear reactions, but as with any large plant you have to bring it up to power gradually, warming large structures slowly so that thermal stresses are not too large. From cold it would probably take a couple of days to get the plant up to full power.

Once you have the reactor fuelled and ready to go, it is just a matter of pulling the rods to achieve criticality, and the power starts to appear. I'm not sure what you mean by 'reproduce nuclear energy'

Full insertion of the control rods on receiving a scram signal takes a few seconds. That is what will have happened at Fukushima, when the earthquake struck. However there is some afterheat produced in the fuel rods, as a result of the radioactivity of the fission products. This is initially about 5% of the full reactor power, but falls off rapidly in the first 24 hours or so. Since the main reactor feed pumps will have probably lost their electrical supplies in the incident, smaller pumps are provided for emergency backup cooling, and for reliability these are supplied from diesel generators. My understanding is that these pumps and their diesel supplies survived the earthquake, but were then knocked out by the tsunami which arrived some time afterwards.

What is the difference between nuclear energy and light energy?

Light is electromagnetic energy. Nuclear energy is energy derived from nuclear reactions, and the nuclear reactions could be either fusion or fission reactions. As regards the energy that appears from nuclear reactions, it can take different forms, including the form of electromagnetic energy.


How is nuclear energy sustainable?

nuclear energy is produced by taking advantage of natural decay in large nuclei of atoms. atoms with large enough nuclei can only be produced by very large scale nuclear fusion such as stars during a supernova, and making it on earth would take enormous amounts of energy. So no, nuclear energy is not totally sustainable, but a small amount of fuel lasts a long time. For this reason energy can be stored by scientifically making large nuclei atoms and utilizing them later.


Is nuclear energy active energy?

Yes, atomic energy comes from the atomic nucleus so it can also be called nuclear energy.


What are the arguments against nuclear energy?

There are many different problems with nuclear energy as it can be highly dangerous and if not used in a proper way it can be lethal. To use nuclear power it is very expensive project which can be reaching the totals of £65 billion. It can take a very long time for some think to be less radioactive as many radioactive substances have a very high half life.


How long does it take to develope a nuclear power?

it takes about millions and millions of years to develope a nuclear power.
