What is Nuclear Energy, How Nuclear Power Plants Works

Published by:

Nuclear power is the production of electricity with the use of controlled nuclear reactions. Nuclear power provided about 2.1% total energy and 15% electricity to date. Obninsk power plant in former USSR was the first nuclear power plant in the world which was established in 1954.it is non renewable form of energy.

How Nuclear Power Plants Works, Technology behind Nuclear Power Plant
The production of electricity in nuclear power is dependent upon the process of nuclear fission. In this process of nuclear fission, the nucleus of an atom is segregated into further smaller parts. These free nuclei and neutrons produce energy in the form of photons or Gamma rays. It is necessary that the total energy contained in the final product is more than that of the supporting starting element. This would help the fission to provide maximum energy during the process. In simple words, in the process of nuclear fission the less powerful free nuclear are converted to more energy containing substances (nuclear). This chain of nuclear reactions generates energy to support nuclear power houses and nuclear weapons. The energy required to supply power to nuclear power plants is created in a controlled manner by using nuclear poisons. Cooling system is often used to shift the energy from reactor to some other place in the plant. This energy is used in the form of thermal energy to heat steam turbines which then run electric generators to produce electricity. The energy resulting from the nuclear fission’s million times more than the energy from the oil and gas, but it is not fully utilized in order to reduce the harmful effects of radioactive waste.

Cost of Nuclear Power Plant, Advantages & Disadvantages of Nuclear Power Plants
The initial investment require for the nuclear power plants is very high. These nuclear power plants may cost up to $10 to $20 billion. This high cost and the limited production of the uranium are the main factors associated with the high cost of project. The nuclear power plants are really efficient in terms of energy production but they increase the need for decaying nuclear waste. The proper disposal of the nuclear waste is also another important consideration while calculating the cost of power plant. The return on investment from these power plants takes a long time because the construction period of nuclear power plants is very high. It is important to analyze the price of fuel used in nuclear reactors which is most commonly known as uranium. Moreover nuclear power plants are a high risk if they are not secured properly form internal and external threat. Last but not least the cost of storing nuclear waste and decomposing it is a major concern and issue for the nuclear power plants.

Some Interesting Facts & Uses Regarding Nuclear Energy
Nuclear energy is derived using uranium which is more commonly available in earth’s crust as compared to silver. This natural resource is used to generate electric power and 95% of the total fuel can be recycled for further use. Producing electricity from uranium is much inexpensive than producing the same amount of energy from natural gas. For example if the price of uranium is doubled in the coming year it would have only 7% increase in electricity cost. However if we double the price of natural gas the cost of electricity would reach up to 70%. The solid waste discharged by the nuclear power plants is a major cost consideration before constructing the plant. It is only efficient energy power plant which is common to both developed and under developed countries of the world. For the decomposition of nuclear waste and radioactive waste separate toxin generated plants are constructed.

Quest for renewable sources of energy reaches us to the nuclear energy which is not only renewable but also environment friendly. Nuclear Energy is discovered accidentally that some of the elements emit radioactive rays due to their natural characteristic. This radioactivity, if harness properly into chain reaction would be an immense source of energy till the stability level of the atom achieved by the element. Nuclear energy is an amazing source of energy which is originated from mass when atom is breaking down into its particles or combining the particles. The process continues till the decay level reaches. In another words an atom is capable of producing energy in three different ways; fission, fusion and decay. All the three methods reluctantly produce enormous amount of energy when compared to other sources of energy like coal or oil.

The concept of nuclear energy has taken from the stars like sun which is a sustainable source of energy. Sun is a big hydrogen ball in which fusion reaction is continued from centuries and is expected to be continued till the end of this universe. The nuclear reaction is the cause of fusing the hydrogen element into helium with the release of energy and this become the chain reaction unstoppable.

Observing the phenomenon of nuclear reaction in sun which is giving heat and energy since the existence of this universe, scientists and physics are continuously busy in devising such phenomenon on earth. We have different examples of nuclear reaction that are the result of either fusion or fission. Fusion, as it is seen in the form of sun, is very difficult to create on earth. However fission is experimented in different ways. In this method radioactive elements like thorium, uranium and plutonium, etc are split and while splitting they also emit nuclear energy which is used to convert into electricity or move the turbine to run generator.

Nuclear reactors are designed to produce heat at a certain temperature used to break an atom as a result of fission which is kept in the reactor portion. Primary and secondary pipes are interlinked to transfer heat from primary to secondary column where it is converted into steam. This steam moves the turbine to produce electricity or to run generator.

Nuclear energy produces in fission is very useful and can better serve humanity if handles carefully.

  1. It is already said that nuclear energy is safe for the environment. It emits no harmful gases during its production process. While the nuclear reaction happens in the nuclear plant it emits no gases like CO2 etc that are harmful for the environment. Coal and oil are the main sources for the global warming and greenhouse gases effect. Nuclear energy is a great incentive for the production of electricity with no after effects.
  2. Nuclear plant is advised to keep away from the habitat and is relatively of small size as compared to other fuel plants. There are no by products and no production of harmful gasses in the process of fission. Nuclear energy is directly consumed in the form of electricity or to run turbines. It occupies less space and even then produces huge amount of nuclear energy.
  3. The only by product in the process of fission is that of water. The water is clean and without any harmful contaminants. This water is also comes out in a normal temperature and is therefore not dangerous for the aquatic life.
  4. Normally where there is a nuclear plant, the surrounding is covered with water and is therefore quite fresh environment seen over there. It can be a suitable habitat for the wild animals and birds.
  5. Nuclear energy is produced I a large quantity and can serve a large area with electricity. It is not only good for the country as it is now becoming a big source of energy. It is secure and useful in the long run.

CAUTION: It is fact that nuclear plant emits radiation that is harmful for the living things. But the amount of radiation is so less that it does not prove dangerous however in the long run it can deteriorate the surrounding. Therefore security measures are required to protect the living things that could be affected by radiations.

What is Non-Renewable Energy, Uses, Types & Resources

Published by:

Non-renewable energy is that source of energy which can not be used again and again. This sort of energy is sustainable to exhaustion. These non-renewable energies like coal, oil and gas are getting scarce. Energy sources like oil, coal and gas are known as fossil fuels.

Non-Sustainable & Non-Renewable Fossil Fuels
The natural resources like oil, coal and gas are formed into the earth’s crust in a period of decades. These energy sources can not be used again and grown in few days. Nuclear energy is the only form of non-renewable energy form which can be reused. 95% of nuclear can be used again to support electricity power plant. Non-renewable energy sources like coal and oil are getting scarce because the supply cannot meet the demand currently. Natural resources like oil and gas are major fuel component of almost all the industries of the world. The problem with most of the energy sources is that the supply is limited to the few hands. These forces can control the prices of these resources. Oil prices are rising at the will of oil producers in the world like OPERA. The downside of non-renewable energies is that these resources are controlled and owned by few countries and the reservoirs are limited. Moreover these energy sources are blamed for global warming. Our dependence on these sources has given way to extreme competition in the international market for the buying and selling of non-renewable energy sources. This is the reason why major economies of the world are switching to renewable energy sources like sunlight, wind, hydroelectricity and tidal power.

Uses of Non-Renewable Energy & Types of Non-Renewable of Energy
Non renewable energy is that form of energy which is subject to deletion. This type of energy is of many uses to us. It can be used to produce electricity, heating, cooking, transportation and manufacturing. 85% of the energy used in the industrial processes is form the non-renewable type of energy. Coal is the most abundant natural resource and it is present in the quantities of trillion of tons. Coal reserves are most prevalent in Europe, Asia and USA. Second abundant non-renewable energy resource is oil. Oil is present in the earth’s layer which is termed as Shale.

This energy resource is converted to gasoline, jet fuel, heating oil like kerosene and diesel. The production of natural gas is the result of activities used to produce oil. Natural gas is not only the base of industry but also it is transferred to domestic users by using pipes. All of the above mentioned energy products are used to generate electricity at large. Moreover they are used in mixed and processed form as fuel for various applications. Nuclear power plants are another form of nonrenewable energy whose use is dependent upon the mining of uranium. Uranium is also naturally found in earth. Uranium power plants are highly efficient in terms of energy production. Uranium is found even more commonly than silver. The energy from the uranium is extracted by nuclear fission in a controlled environment.

Benefits of non Renewable Energy Sources
The energy sources like coal and oil are naturally present in the earth. The mining of coal is relatively cheap and easy. Oil is very efficient form of fuel. All of these energy sources are easy to extract from earth and are convenient to use. Natural gas is much more environment friendly than coal and oil. The use of small amount of nuclear energy produces huge amount of heat with only small emission of radioactive substances. The only downside with the use of non-renewable energies is that they are depleting and are a cause of pollution.

Causes of Air Pollution

Published by:

Air consists of different gasses which readily react with other chemicals. These other chemicals sometimes come from natural environment make up of ecosystem and mostly human activities are responsible for the increasing level of air pollution. Therefore it is very necessary to control such processes which are the cause of air pollution. Among these processes the chemicals which form and also are harmful for the environment are carbon dioxide is the most common pollutant.

Human beings are the main and elementary source of carbon dioxide though not so harmful. But increasing population is becoming problem for the environment as plants are removed from a vast land areas and habitation is taking its place. This results in the form of extra carbon dioxide which is consumed by the plants. So exhalation of CO2 by human beings is also becoming danger to the air pollution. The secondary cause of carbon dioxide emission is burning of fuel.

Fuel burns in vehicles like planes, trains and cars and they are not few in number. As population is increasing the ratio of all these transportation is also directly proportional and doubles the production of carbon dioxide. This fuel is commonly fossil fuel which is very effective for the transport and also a major source of emission. Now-a-days many other renewable energy sources are introduced to replace the fossil fuel so that there is less possibility of CO2 emission.

Fuel burns in factories is another great cause of the air pollution. This fuel while burns produce a smoke of different chemicals used in different manufacturing processes. This smoke is the mixture of different chemicals and makes smog with the fog present in stratosphere layer. Smog is a very dangerous pollutant for breathing diseases and skin problems. Sulfur is an important ingredient of this smoke and together with nitrogen which is already present in large amount in the air is the cause of acid rain. This acid rain is a sever enemy of living beings on earth. The whole ecosystem infects due to acid rain. Living beings like fish, cattle, pet animals and plants.

Air is mostly recognized as O2 gas which is an evidence of human life on earth till it is present on the planet. But increasing pollution has been including different oxides due to chemical reaction which is converting oxygen into O3. O3 is known as ozone gas a poison to the life. There is dire need to slow down artificiality from life and more dependency on the natural resource so that the process of air pollution slows down.

Different types of radiation are emitting radioactive carbon in the air. Radioactivity is a burning chemical for the skin and is causing severe skin diseases among living things. The latest technologies like the latest touch screen technology are a bigger cause of radioactive rays. This emission is a silent killer to our different organs used in daily life as it affects the hearing, seeing, and touching senses commonly and the inner hidden system of man generally. We are making use of harmful rays in refrigerator, microwaves, computers and mobiles all are the sources of harmful rays and could be a possible cause of physical impairments.

Eruption of volcanoes and burning of jungles are also the causes of air pollution. Volcanoes not only barren the soil for years not able to cultivate but also spread harmful gasses in the environment which causes number of abortions and skin cancers. Burning of forest every year in the hottest areas is the cause of producing greenhouse effect in the air. Greenhouse gasses are increasing the temperature of planet earth and glaciers are melting which is making a sort of environment not favorable to human existence.

What is Biomass Energy

Published by:

Biomass energy is another form of renewable energy source and it is derived from living or dead organisms like plants, waste and alcohol mostly. Biomass energy is getting widespread popularity nowadays. Biomass energy source is most often derived from plants either to generate electricity or to produce heat.

Sources of Biomass Energy: Biomass Energy Sources

Biomass energy is derived form various sources which help in generating sufficient energy for use. The various source of generating energy from biomass are wood, waste, alcohol, garbage, landfill gases. Wood is either taken from trees or from the waste of industrial processes. The waste material of industry like paper making is really helpful in providing pulping liquor. The second major source of deriving biomass energy is from the solid waste. This solid waste is either provided by municipality waste or industrial waste. When energy is extracted either from alcohol or from the fiber present in the corn, it is termed as ethanol fuel. This ethanol fuel is really helpful in providing fuel to the cars and farm tractors. Biomass energy can also be extracted from various kinds of plants like polar, willow, hemp, corn, miscanthus, sugar cane, spice trees, eucalyptus, palm oil, switch-grass and shorgum.

Conversion of Biomass to Useful Energy

The conversion of Biomass into useful energy can produce heat and electricity moreover it can also be converted to bio fuels. There are three ways of converting waste and wood into useful biomass energy and bio fuels. These methods include thermal conversion, chemical conversion and biochemical conversion. Thermal conversion is the process in which various bio organisms are converted to chemical formations using heat. There are many ways to perform this conversion like combustion, torrefaction, gassification, prolysis, hydro processing and hydro-thermal upgrading. A typical thermal biomass plant is 20% to 30% efficient. Chemical conversion is the process of converting various waste materials and liquid slurring into fuels by using chemical reactions.

The natural materials like biomass are made up of molecules. In order to break these molecules, living enzymes like bacteria and other micro organisms are used. These micro organisms are helpful in performing processes like fermentation, compositing and digestion. However the process of producing ethanol from used or fresh oil is known as transesterfication. Biomass fuels are also generated by converting starch and sugar from sugar cane into alcohol. This is the same alcohol which is used for drinking. These processes are still underdevelopment and scientist worldwide is searching for the ways to improve them.

Advantages and Disadvantages of Biomass Energy

There are many advantages and disadvantages of Biomass Energy. The biomass is used and produced throughout the world. It is the most inexpensive way of producing electricity. So far it looks like an inexhaustible natural resource. Biomass energy as a renewable energy source is capable of replacing fossil fuels. Agriculture biomass energy products add more worth to agricultural activities. The growth of biomass plants and crops produces oxygen and utilize more carbon dioxide present in the air. The use of solid waste from industry and municipality helps in lowering the amount of waste. The use of biomass energy can help lower the pressure of buying foreign oil.

Alcohol, methane and ethanol are quiet efficient and environment friendly. However if these bio masses like wood and waste is burnt directly it can discharge immense pollution into the environment. Therefore it can be viable source of global warming. Biomass technology is still under the phase of development. The energy produced in the thermal conversion is the net energy. Hence there are methods require to improve the feasibility of biomass energy projects. In order to increase the potential and availability of biomass energy more research is needed.

What is Atomic Energy

Published by:

An atom is made up two parts; nucleus is the center around which electro is moving. Nucleus has positive charge with proton and neutron inside and electron has negative charge. Both negative and positive charges attract each other. The nucleus, under nuclear reaction, when fuses or fissures huge amount of energy is produced which is known as nuclear energy or atomic energy.

Atom has immense amount of energy stored in its nuclei. Nuclear reactions are the cause of harnessing atomic energy. Sun is the example of fusion reaction in which hydrogen is continuously fusing and making helium. As a result of this nuclear reaction atomic energy produced which is uncontrollable. Hydrogen atom when bombarded with neutron split into two and produce atomic energy. This however explosive for example hydrogen bomb or you can say atomic bombs are the most destructive weapons example of this atomic energy. Similarly, uranium is broken down by neutron hit on its nuclei and continuous process of splitting uranium starts called chain reaction. This characteristic of producing atomic energy in a chain reaction is the cause of long term fuel fulfillment so that it would be enough for a year.

Advantages of Atomic Energy

Sustainable Energy
With the increase threat of finishing the resources of coal and oil scientists were desperate to find a renewable sustainable source of energy. This is also evident from nuclear reaction in the form of chain reaction as tiny amount of uranium is capable of producing energy that is sufficient for long term energy requirement.

No by Products
During the procedure of nuclear reaction no byproducts like CO2, CO are formed. Large amount of byproducts in the form of waste are produced during the harnessing of coal or oil quite opposite to the nuclear power plant where there is no signs of heap of waste outside. Only water is the byproduct in case of nuclear reaction of an atom for atomic energy.

Less Consumption
A small amount of radioactive element is sufficient as compared to the traditional fuel. Nuclear power plant is processed with a very little quantity of radioactive element. Atomic Energy is therefore very cheap source of energy. A ton of uranium could produce as much energy as million tons of fossil fuel.

Environment Friendly
Traditional sources of energy are the big reasons of environment pollution. A secure power plant is environment friendly and does not produce any contaminants to the outer environment. Mostly water that is produced as a byproduct is found around the plant and give a fresh look to the surrounding.

Disadvantages of Atomic Energy

Explosive
Atomic bombs are made from nuclear reactions so are dangerous. There are around half millions of weapons present in only Russia and America. This explosive nature of atomic energy is presenting future threats that in case of negligence or without safety measurement the atomic energy can be destructive. You would surely thinking about those nuclear wars which America invaded on Japan in Hiroshima and Nagasaki.

Radiation
Being a radioactive element a large amount of radiation produces from nuclear reaction. This radiation is very dangerous for the living beings in the long run. Meltdown is the terminology associated with the radiation emitting from the atom. Nuclear reactor in Three Mile Island creates a chaos out of none. Similarly, Chernobyl nuclear plant accidently emitted radiation that causes a lot more people died on the spot while number of people died with cancer as an after effect of this.

Nuclear Waste
Radioactive element once breaks down into its nuclei particles and emits radiation from its waste even. Nuclear waste is so dangerous that even a touch could kill a person. It is therefore special power plants are made to keep the radiation restrict and protect the outer environment.

Long Term Promise
Atomic energy is the energy that once nuclear reaction started it takes the form of chain reaction which makes us view as energy on long term. It is said that near a half decade is the normal life of nuclear plant.

Advantages of Recycling

Published by:

Scientists and researchers are busy to find out alternate resources as they are guessing the present reservoirs to be ended soon. What the dilemma it is!

 

Dilemma

Everything even man-made has nature as its basic ingredients. It means we are consuming nature if we are increasing the production. This point has taken too much time to be realized by the scientists and researchers when we have been reaching near the bottom of treasure. It means we spoil the precious treasure of nature without bothering about its importance. If we continue the same cycle there is no doubt we spare nothing for the coming generation. We must admit this fact that we have messed up the nature now it is time to reset all.

 

Savior

This is the time to take advantage from the recycle process. Instead of producing new things from the raw material snatching from the nature we must recycle the present amount of things. Present production quantity is more than enough for the population. Recycling is a reproduction plant which uses the readymade material. This readymade material has been used by the public and is discarded by them as waste material. While reproducing the used material through the process of recycling we are going to take unimaginable advantages.

 

Life Insurance

On the first place when we recycle an item we start contributing our part to save nature. Recycling means no deforestation, less consumption of water and fossil fuel. These are the most used and the most important components. If they would finish or lessen the life duration can be short as well. Recycling helps to preserve the nature for the coming generation.

 

Hygiene

Recycling helps to reduce the waste material around us which guarantees the clean surroundings. Waste attracts germs and gives birth to the harmful diseases. Different viral diseases are also common around waste heap which are sometimes long lasting as asthma or flu. Recycling provide opportunity to keep clean an organized trash disposal.

 

Saving Bank Account

Recycling is like your saving account which is profitable in the long run. If you do recycling it will give you so many benefits in return. You can see it like this account is giving you 40 % benefit per year on your balance. Recycling triangle makes profit in a triangle means all round.

It means recycling is benefited in every aspect that neglecting few disadvantages does not matter. Recycling process is a short duration process as there is no need to start from zero half material is already in prepared form. This thing saves enough time to spend free quality time with family.

There is also advantage of saving money as waste is obtained mostly free and sometimes can be purchased at low price as a second hand thing. Purchasing raw material needs heavy investment to start a new business while recycling business can be start with a little money.

Another advantage comes in the form of energy. We need energy to perform our day to day work when work is done in less time we find ourselves more energetic and relax. Energy conservation is not only done in body form. There are all those natural resources contributing their energy in the form of raw material and fuel. Recycling save all these types of energy as instead of using active raw material energy we are consuming the passive energy of waste material. Different types of waste materials like plastics, glass, wood and metal can be recycled more than thrice. It means we can preserve energy and consumed by recycling waste.
