Nuclear Power

What’s Nuclear

power??Nuclear power is energy contained in atoms. This energy can be released as heat from a chain reaction in a radioactive element such as uranium. Nuclear power stations use this heat to produce steam, which drives turbines to generate electricity.

TWO WAYS TO OBTAIN NUCLEAR ENERGY:

1. Nuclear fission 2. Nuclear fusion

Nuclear fission and fusion:

Nuclear fusion and nuclear fission are two different types of energy-releasing reactions in which energy is released from high-power atomic bonds between the particles within the nucleus. The main difference between these two processes is that fission is the splitting of an atom into two or more smaller ones while fusion is the fusing of two or more smaller atoms into a larger one.

Uses of nuclear energy:

Nuclear Transport - There are a number of transport modes like Ships and Submarines which use Nuclear Based Propulsion.Note for the Military,Nuclear Submarines are of the most lethal weapons capable of staying under water for very long periods which diesel submarines are incapable of. Medical Applications – Nuclear Energy finds wide applications in Medical Science.Use of Nuclear Energy for X-Rays,Chemotherapy Treatments is widely known and accepted.Space and Futuristic Applications – While this technology is still immature and not widely used,Fission Reactors for powering rockets and space vehicles is very useful as the energy generated by small mass is possible which is not possible by chemical energy means.Nuclear Fusion has been said to be the holy grail for generating almost infinite amounts of energy at low cost.R&D continues to be done to develop this and other forms of Nuclear Power like Breeder Reactors etc.

Food and Agriculture – Radioisotopes and radiation used in food and agriculture.Sterile Insect Technique (SIT) involves rearing large numbers of insects then irradiating them with gamma radiation before hatching, to sterilize them. The sterile males are then released in large numbers in the infested areas. When they mate with females, no offspring are produced. With repeated releases of sterilized males, the population of the insect pest in a given area is drastically reduced. Electricity - This is the greatest use of Nuclear Power using Nuclear Fission.According to WNA “Sixteen countries depend on nuclear power for at least a quarter of their electricity. France gets around three quarters of its power from nuclear energy, while Belgium, Bulgaria, Czech Republic, Hungary, Slovakia, South Korea, Sweden, Switzerland, Slovenia and Ukraine get one third or more. Japan, Germany and Finland get more than a quarter of their power from nuclear energy, while in the USA one fifth is from nuclear. Among countries which do not host nuclear power plants, Italy gets about 10% of its power from nuclear, and Denmark about 8%.”

Facts of nuclear Energy:

There are roughly 430 nuclear power plants worldwideThere have been three major nuclear power plant disasters which occurred in 1979, 1986,and 2011.The nuclear accident which occurred in 1979 took 14 years to clean up.The United States produces more nuclear energy than any other country.Since the nuclear disaster of 2011, many nuclear power plants have shut down operation due to

safety concerns.Radiation and nuclear medicines are used to cure and treat many diseases.Uranium is a rare earth metal that is commonly used for nuclear energy production.Africa is the first country in the world to destroy all of its nuclear weapons voluntarily.Although there have been three major nuclear power plant accidents, they are said to actually

be quite safe places.Fourteen percent of the world's electricity is generated by nuclear energy.Scientists who study the interactions of atoms' nuclei are called nuclear physicists

Advantages of Nuclear Energy:

Almost 0 emissions (very low greenhouse gasemissions).

They can be sited almost anywhere unlike oil which ismostly imported.

The plants almost never experience problems if notfrom human error, which almost never happens anywaybecause the plant only needs like 10 people to operateit.

A small amount of matter creates a large amount ofenergy.

A lot of energy is generated from a single powerplant. Current nuclear waste in the US is over 90%Uranium.

If reprocessing were made legal again in the US wewould have enough nuclear material to last hundreds ofyears.

As the core gets hotter the reaction gets slower, hence a run-away reaction leading to a melt-down is not possibleModern reactors have two to ten times more efficiency than the old generation reactors currently in use around the US. New reactor types have been designed to make it physically impossible to melt down.

Disadvantages of nuclear energy:

Nuclear plants are more expensive to build and maintain.Waste products are dangerous and need to be carefully stored for long periodsof time. The spent fuel is highly radioactive and has to be carefully stored formany years or decades after use. This adds to the costs.There is presently no adequate safe long-term storage for radioactive andchemical waste produced from early reactors some of which will need to besafely sealed and stored for thousands of years.Nuclear power plants can be dangerous to its surroundings and employees. Itwould cost a lot to clean in case of spillages.

There exist safety concerns if the plant is notoperated correctly or conditions arise that wereunforeseen when the plant was developed, ashappened at the Fukushima plant in Japan.nuclear plants can render hundreds of square milesof land uninhabitable and unsuitable for any use foryears, decades or longer, and kill off entire riversystems .A lot of waste from early reactors was stored incontainers meant for only a few decades, but is wellpast expiration and, resulting, leaks are furtheringcontamination.

A nuclear power plant is a type of power station that generates electricity using heat from nuclear reactions. These reactions take place within a reactor. The plant also has machines which remove heat from the reactor to operate a steam turbine and generator to make electricity. Electricity made by nuclear power plants is called nuclear power.

What is nuclear Power plant??

Nuclear Reactor:

A nuclear reactor is a machine that uses fission to generate heat. There are different designs which use different fuels. Most often, uranium-235or plutonium-239 are the main components of these fuels.Most nuclear reactors are used to make electricity. In nuclear power plants heat from the reactor changes water into steam. The steam is then used to power electric turbines which make electricity. It is important to remember that the turbines do not change the temperature of the steam, or the amount of steam. Instead, the turbines take energy from the movement of the steam.

Nuclear power plants, and that our country !! Like a dream, is not it? The technology-rich countries in the world's major nuclear power plants boast. On 02 November last 2011 nuclear power production in Bangladesh and Russia signed an agreement. Agreement on behalf of the Minister of Science and Technology of Russia and the Russian Atomic Energy Agency Osman (ROSATAM) Director General Sergei kiriyesko signed. According to the agreement of the Russian ROSATAM IshwardiRooppur 1000 MW taderaraifinanced through credit facilities, two nuclear power plants, which

means it will sit. Whose work began in 2014 by the year 2018 is expected to be finished, and since 2018, at least 1 of the nuclear plant, according to the power supply can be found. Note that there is currently a shortage of electricity, which is about 1500 MW by the year 2018 and reach 2000 MW, of which the demand can be met by nuclear power plants. The nuclear power plant project cost is counted as 1.5 - 2.0 billion. The nuclear power plants will need to enable efficient manpower and a half to three thousand.
