Is nuclear power plant renewable?
Nuclear fuel (uranium) is not renewable. The plant itself has a life based on deterioration of important components, especially the main reactor pressure vessel. This is subject to intense neutron bombardment during operation, and at present can only be licensed (in the US) for up to 60 years. At the end of life it would have to be scrapped, so it is not renewable.
What are the disadvantages of electricity?
1. Electricity can cause pollution if it is generated by fossil fuels, or nuclear energy. It can affect animal life if it is generated by hydroelectric dams or tidal power. 2. Electric devices, circuits, conduits, and transmission lines present a shock hazard to people: those who use it, those who work with it, and those who provide it. Short circuits and sparks also present a fire hazard. 3. High voltage lines are thought to cause hazards to plants, animals and people who live near them, because they produce magnetic and EMF fields. 4. People who have become dependent solely on electricity may be unable to function without it in an emergency.
What are the main components of fire?
Chemically, a fire is made up of four components; the reaction itself, the fuel, oxygen, and heat. A fire cannot burn unless these four components are present in the correct proportions. The flame consists of a mixture of reacting gases and solids emitting visible and infrared light.
What is photoelectric switch?
Switches, used mainly for situations such as sentry devices or outside lights. The generation of electricity by the photovoltaic cell when light is present.
What is produced when there is resistance to the flow of electrons?
It depends on the nature of the device acting as the resistor. All basic circuit components act as resistors. Resistors dissipate energy from the current in the form of heat. Capacitors store energy in a electric field. Inductors create a magnetic field.In practice in general, heat dissipation is present in most resistive devices (including circuit wires). So common, in fact, that we call it "internal resistance". But that is effectively how we use electricity: by resisting its flow.
What types of nuclear energy generates electircity?
At present only nuclear fission can be used, in various types of reactor. The PWR and BWR are the most commonly used.
When is nuclear energy going to be used as an everyday energy?
You clearly don't understand how electricity is distributed. At present in the US nuclear power electricity is about 20 percent of the total used. This means that just about everybody uses some nuclear every day as part of their use of electricity. Nuclear power is always going to be used to produce electricity, you won't ever have one in your basement.
What process generates the heat and energy in present day nuclear power plants?
Nuclear fission is the process that generates heat and energy in present-day nuclear power plants. In this process, the nucleus of an atom is split into smaller nuclei, releasing a large amount of energy in the form of heat. This heat is then used to generate steam, which drives turbines connected to electricity generators.
How long will nuclear energy for electricity production last at the present rate of usage?
There is no telling we give it an estimate of twenty years.
How long can HIV virus stay outside the blood?
As long as the infected cellular matter is present, or may be it depends till the nuclear components of the cells decompose.
How much nuclear is available?
In the US there are 104 operating reactors at present, and they produce about 20 percent of the nation's electricity. World wide the figure is over 400 reactors and they produce about 15 percent of the world's electricity.
What fields are present near electricity?
Fields such as magnetic fields and electric fields are present near electricity. These fields are created by the flow of electric current through conductors and can interact with nearby objects and living organisms. It is important to be aware of these fields and take appropriate safety measures when working with electricity.
Do power stations use heat to generate electricity?
Yes most power stations do use heat to generate electricity. Heat energy of the fuel (e.g. burning coal, burning oil, nuclear fission) is utilized to heat water present in the boiler. This heating generates steam, which is then utilized to run the turbine. However some power stations get the energy to generate electricity without using heat (e.g. hydroelectric dams, wind power, sea wave power, solar cell generation systems).
How is nuclear energy is useful?
NUCLEAR DEBATE 1)Proponents of nuclear energy assert that nuclear power is a compact, reliable sustainable energy source that reduces carbon emissions and increases energy security. Proponents highlight that nuclear energy's operational safety record is already very good when compared to other major power plant technologies. They claim that the risks of waste and other environmental impacts are small compared to other sources of electricity and can be further reduced by improved technology in new reactors. 2)Mainly to produce electricity. Also to produce radio-isotopes for medical and industrial use 3)The two "basic types" of nuclear energy are based on fission and fussion. Fission is basically atom splitting. Fusion is the forcing together of nuclei and causing them to fuse, to stick together, and to form a new nucleus. In both nuclear reactions, a lot of heat is generated. The reactions can be set up to occur "really fast" and release energy all at one. This the idea behind the nuclear weapons. There is another idea. Because the primary useful energy released in nuclear reactions is heat, that heat can be captured to do useful work. At present, we can't do any "controlled fusion" and capture heat to generate electric power. But we can use fission to our advantage to make heat to boil water to generate steam to turn a turbine to turn a generator and make electricity. And we do this pretty well.
What is nuclear fusion and fission use for?
Nuclear fission is used as the principle of operation for a total of 104 nuclear power reactors in the US, producing 806.5 billion KWh of electricity in 2007. Worldwide figures in 2006 were 2659.7 billion KWh. Nuclear fusion has no use at present except in H-bombs, which hopefully will never be used in anger.
What are food components?
The nutrients present in the food are called food components
What is it called if the nuclear membrane is not present in the nucleus?
If the nuclear membrane is not present in the nucleus it is called untrue nucleus, prokaryotic feature.
