Nuclear power plants are capital intensive power plants and hence it is more economic to operate them at high capacity factors (or as base load plants)

What are the three requirement for a complete circuit?
-- a power supply -- a load -- low-resistance material to connect the load to the power supply
How many vA equal to 1watt?
In a.c. circuits, the watt is used to measure the true power of a load, and is determined by multiplying the supply voltage by the load current by the power-factor of the load. The volt ampere is used to measure the apparent power of a load, and is determined by multiplying the supply voltage by the load current. So the relationship between the watt and the volt ampere depends on the power factor of the load. For example a 100 VA load with a power factor of 0.8 (leading or lagging) will have a true power of 80 W.
How do you consume electricity in maharashtra?
Power is consumed whenever a load is connected to the distribution supply panel.The load is usually controlled by a switch, contactors for motors or breakers located in the distribution panel. Load on line power is consumed, load off line no power is consumed.
What percent of the world's energy does nuclear fission supply?
* There are now some 435 commercial nuclear power reactors operating in 30 countries, with 370,000 MWe of total capacity.* They supply 16% of the world's electricity, as base-load power, and their efficiency is increasing. Source: www.world-nuclear.org
What pieces of information are needed before selecting a power supply?
The main piece of information needed is the load wattage or amperage that will be connected to the power supply. Once this is known the power supply of a greater size that the load should be chosen. Also with this information the size of the wires can be calculated from the power supply to the load. Too small a wire will create a voltage drop at the load end of the circuit. This will cause under performance of the load.
Should nuclear power plants be phased out?
These plants provide base load stability to the electrical grid system while producing no greenhouse gas
How do nuclear power plants transfer energy?
The fission energy of a nuclear reactor is heat. It makes steam which runs a turbine electric generator. The electricity is put on the power grid and is sent to the load.
Is nuclear energy expensive and available at all times?
The generating cost is much the same overall as coal, the fuel cost is lower but the plants are more expensive to build. Most nuclear plants run on base load because the fuel cost is lower.
How is nuclear power distributed?
All electrical power from large plants is fed into a grid system and distributed along high voltage lines, to wherever the load is required, which will include large cities and industrial areas. So nuclear power is no different to fossil fuelled power.
Is nuclear energy available at all times?
Nuclear plants are normally run on base load, that is at a constant output, because they run with lower fuel costs than fossil fired stations. Where there is a high proportion of nuclear plant, as in France at 75 percent, some of the nuclear plants will have to load follow, that is respond to changes in national load demand, but I don't think this applies in the US with only 20 percent nuclear. Stations with higher fuel costs would be shutdown at night or other low load periods, rather than nuclear, so yes there will always be some nuclear being generated at any time.
What is the difference between Base loads and peak loads in power system?
What is the difference between base and peak load?Load is the amount of power in the electrical grid. Base load is the level that it typically does not go below, that is, the basic amount of electricity that is always required.Peak load is the daily fluctuation of electricity use. It is usually lowest in the wee hours of the morning and highest in the early evening. It also varies seasonally.Are base and peak loads provided differently?Base load is typically provided by large coal-fired and nuclear power stations. They may take days to fire up, and their output does not vary. Peak load, the variable part of the electrical supply and demand, is provided by more responsive and smaller plants whose output can be quickly ramped up and down or that can even be quickly turned on and off.
How many nuclear power plants are in the world?
There are 436 nuclear power plants in the worldThere are 441 nuclear power plants in the world. Please see the Related Link below for more information.442 as of January 19th, 2011.433 - ( under construction 185 - planned 158)There are about 430 nuclear power plants worldwide, depending on how you count them. This number does not include the plants used to power ships, of which there are something over 150. Nor does it include research reactors that do not provide electrical power to a power grid. Also not included are small nuclear power plants, such as are used in hospitals for the production of radionuclides for medical use.Use the link below to see a list.The entry says it may not be complete, but there isn't much missing. This list does not include research or prototype plants, and it does say 'major' power plants so there may be a few small ones missing. Also plants which are in decommissioning are not included, so historically there are some which have operated in the past but are now permanently shutdown.
Can wind power be used for base load power?
No. Baseload power sources have to be as reliable as possible. Wind has a capacity factor (actually electric production/nameplate potential) less than 1/3rd of nuclear/fossil thermal sources.
Can nuclear energy be built anywhere?
Nuclear energy from the 104 operating nuclear reactors flows into the high voltage transmission lines, and once that has happened it is just power along with all other sources of electric power, so most areas will have some nuclear power being supplied. Of course the grid controllers determine which way current flows depending on the power stations available at the time and the load demand variations in different places. Nuclear plants are generally operated at full base load power because the fuel costs are much lower than for fossil fuels, so the variations in load demand are absorbed by the coal and gas fuelled stations. If you mean can nuclear plants be sited anywhere, this is a different question. You wouldn't put one in a city or highly urbanised area, and you need a source of cooling water as for fossil fuel stations, so the middle of a desert wouldn't be a good place. On the other hand you are not tied to location of the fossil fuels, as the nuclear fuel can easily be supplied by road truck anywhere there are roads. The other thing is how much consumption there is in an area, there is little point in siting a plant in a remote area and then having to build a new transmission line perhaps hundreds of miles to where the load can be used.
Why do power plants rely on nuclear Energy?
To produce energy more than any other source can produce. A handful of Uranium can produce enough energy as the same as 4000 Train Load of coal [Given that each train load has around 15,000 Tons of Coal.]
Is nuclear power quite cheap to run?
The fuel cost is lower than for fossil fuel, so once the plant is built it tends to be run continuously on base load at full power, to take advantage of this. Taking the high building cost into account, there is probably not much difference overall between nuclear and fossil.
How much nuclear energy is produce yearly?
* There are now some 435 commercial nuclear power reactors operating in 30 countries, with 370,000 MWe of total capacity.* They supply 16% of the world's electricity, as base-load power, and their efficiency is increasing.
