NUCLEAR ENERGY : How Do Nuclear Plants Work? Part 2

A nuclear power plant using heavy elements to generate electricity. This type of power plant can be used to produce electricity with greater numbers. In most countries this plant is used as a base load power plant (base load). This is because a nuclear power plant can operate for long periods of time and the plant life can last up to 60 years.

Operation

Heavy elements such as Uranium (U 235) or Thorium (Th232) is subject to the fission nuclear energy in a reactor to produce high pressure and temperature steam.

The steam drives turbines will then convert nuclear energy to mechanical energy. This process will then convert mechanical energy to electrical energy.


NUCLEAR ENERGY : How Do Nuclear Plants Work? Part 1

  • Pressurized Water Reactor

Pressurized Water Reactors (also known as PWRs) keep water under pressure so that it heats, but does not boil. This heated water is circulated through tubes in steam generators, allowing the water in the steam generators to turn to steam, which then turns the turbine generator. Water from the reactor and the water that is turned into steam are in separate systems and do not mix.


1. The Fuel
The fuel used in nuclear generation is primarily uranium 235. It is manufactured as small round fuel pellets. A single pellet is less than an inch long, but produces the energy equivalent to a ton of coal. The pellets are placed end-to-end into fuel rods that are 12 feet long. Over 200 of these rods are grouped into what is known as a fuel assembly.

2. Reactor
The process of producing electricity begins when uranium atoms are split (i.e., fission) by particles known as neutrons. Uranium 235 has a unique quality that causes it to break apart when it collides with a neutron. Once an atom of uranium 235 is split, neutrons from the uranium atom are free to collide with other uranium 235 atoms. A chain reaction begins, producing heat. This reaction is controlled in several ways, including by control rods which absorb neutrons. Control rods are inserted among the fuel assembly rods that hold the uranium pellets. When they are in place, they absorb the atomic particles that would normally initiate the chain reaction. When they are withdrawn from the fuel assembly, fission is allowed to occur.

3. Pressurizer
The heat produced in the reactor is transferred to the first of three water systems: the primary coolant. The primary coolant is heated to over 600 degrees Fahrenheit. In a pressurized water reactor, a pressurizer keeps the water under pressure to prevent it from boiling.

4. Steam Generator
The hot, pressurized water passes through thousands of tubes in nearby steam generators. These tubes are surrounded by another water system called the secondary coolant. The heat from the primary coolant is transferred to the secondary coolant, which then turns into steam.
The primary and secondary systems are closed systems. This means that the water flowing through the reactor remains separate and does not mix with the water from the other system or the lake.

5. Turbine
The steam is piped from the containment building into the turbine building to push the giant blades of a turbine. The turbine is connected to an electric generator by a rotating shaft. As the turbine blades begin to spin, a magnet inside the generator also turns to produce electricity.

6. Condenser Coolant
After turning the turbines, the steam is cooled by passing it over tubes carrying a third water system, called the condenser coolant or lake water. The steam is cooled so it condenses back into water and is returned to the steam generator to be used again and again.

7. Lake or Cooling Towers
At some nuclear stations, lake water flows through thousands of condenser tubes to condense steam back to water. It is then discharged down a long canal (for cooling) and eventually enters the main part of the lake. At other plants, the condenser cooling water is circulated through cooling towers to remove the extra heat it has gained. The water is pumped to the top of the cooling towers and is allowed to pour down through the structure. At the same time, a set of fans at the top of each tower pulls air up through the condenser water. This lowers the temperature of the water. After it is cooled, the condenser water flows back into the turbine building to begin its work of condensing steam again.

·                     Boiling Water Reactor

In Boiling Water Reactors (also known as BWRs), the water heated by fission actually boils and turns into steam to turn the turbine generator. In both PWRs and BWRs, the steam is turned back into water and can be used again in the process.



NUCLEAR ENERGY : Why Nuclear Energy?


Conventional Method : Fossil Fuel



Alternative Method : Nuclear Energy

NUCLEAR ENERGY : The Real Energy Source





Nuclear energy is a clean energy compare to fossil fuels such as oil, gas and coal. It also does not contribute to global warming or even toxic chemicals. Pollution caused by fossil fuels causes emissions of greenhouse gases are among the main causes of global warming. For example, a 500 megawatt power plant using fossil fuels releases up to 50 kg of carbon dioxide per second while nuclear power plants do not release this gas.

Almost 95% of electricity generation in Malaysia dependent on fossil fuels, namely coal, gas and oil. The cost of energy consumption will soar from time to time because most of the fuel imported from overseas and will suffer from extinction. Fossil fuels releases the carbon dioxide that contribute to global warming. This causes extreme weather changes occur such as natural disasters, floods, landslides, soil erosion and etc. Therefore, a change towards an effective alternative energy must be given due attention. Malaysia should dare to step into the nuclear era to ensure sustainable energy for a better future.

childhood life

My childhood life
Everyone said when you are a child, you are having a good happy life and you don't have any problems at all.But I think not all children are so lucky enough to have a happy childhood life experience.Me myself,I don't want to judge anyone or cretinize anybody whats going on about their life but what I'm going to talked and shared here is base on my true story about my childhood life. It's different from other normal happy family.I know life must go on but sometimes things happen when you are not expecting it,and you are just asking your self why?
I was a member of a broken family since at my young age of 5 and having a broken family was not so easy at all and the one who are the most suffering are the children. Base on my own experience, I am the one who suffered when my parents got separated.Being so poor already lack of everything then to be a member of a broken family will be the worse thing I ever had in my life.When my dad started to go away from house, I was so sad till I burst into tears without sounds that no one could hear me. I asked "How long you will go?" and begging him not to leave me.Then my dad told me "Don't you worry son I will be back soon an bring something for you ".I told him that I don't want anything from him,just always be my side is enough already. After that,my dad turn his back and I saw he started tears and hug me tightly.I know that action shows that he really love me and I couldn't forget till my last breath watching him went away from house with full of sadness.I can felt that there is something wrong going on but I couldn't said anything even my heart broke to see my dad leave us.I just discovered that my dad is not coming back after I heard a conversation of my grandparents that I need to stay with them for awhile.Staying with them is not my dream at all,even though that I can say that they gave me all their love and attention,still there's something missing.All I want is our family to be complete and reunite once again and that is my wish at all.Now,I realize how hard and completely difficult with full of sadness and trails what happened to my childhood life but i'm sure and know that everything happen there is a reasons and Allah is the most greatest Planner.When we are children we seldom think of the future but we forget to enjoy our childhood moments.As the quote says by Tom Robbins

“It's never too late to have a happy childhood.”
― Tom Robbins


I hold the says by Franklin D. Roosevelt as my inspired motivation,he said that:
“We may not be able to prepare the future for our children, but we can at least prepare our children for the future.”

BABY DUMPING

...BABY DUMPING...



CHILD is a priceless gift from Allah SWT.However,baby dumping is a social crisis and has a chronic increase time by time as many cases are occuring in Malaysian society.The baby dumpinf refers to discarding or leaving alone for a certain time being or another word is their parents did not take care of them.Almost everyday there are reports on dumped baby cases,If you don believe it you can check on the front page of the newspaper or see it on nightly news.

Baby Dumping in Malaysia
I think the most cases about baby dumping was come among teenagers because it always seen to be involved in this situation.
Baby in the Bathroom
Teenage parents give birth in a motel room and leave the child for dead in a dumpster.Next,a girl gives birth in a school bathroom at night after that 
they will throw the baby in the bathroom or dustbin.This cases must take seriously to make sure this cases can control among teenagers.

One factor that leads to child dumping is teenage pregnancy. Teenage pregnancy is defined as a teenage or underage girl becoming pregnant.This pregnancy of teenagers are a mere result of the gratification of sexual urges. That pregnancy might not happen only if studies were prioritized rather than having relationships with the opposite sex. No premarital sex, no early pregnancy. Worst thing about this is that it is the child that will suffer. If not aborted, they are dumped by their biological parents.

Another factor is the family break-up. Family break-ups happen after a long period of misunderstandings, fighting and unhappiness. Sometimes they happen suddenly and it is hard to understand why there needs to be change at all. Children are mostly affected by this kind of situation. If both their mother and father decided to a divorce and one cannot raise their child alone, tendency is that they will dump their child. This child will become homeless and found himself alone.

There are others way to prevent this cases can be reduced in our society and country.For example,


  •  Sexuality Education
            Baby dumping presumbly results from unwanted pregnancy. To prevent baby dumping, it is therefore ultimately necessary to educate individuals about sexuality. we support age-appropriate comprehensive sexuality education, and recomamends that school and communities provide comprehensive sexuality education to all youth and families.
  • The government
            The government also must involve overcoming this problem from step by step and taking this matter seriously. baby hatch is indeed good way to help single mother who cannot afford to take care the baby and nowadays 'sekolah harapan' and Kewaja has already been opened for person who involved unwanted pregnancy.
  • Campaign
    To raise awareness of this issue to the public. One of the campaign's focus is "Kami Prihatin". It was launched on 23rd March 2010 and activities were organized to promote child protection policy, producing a documentary and publishing community awareness advertisements in Utusan Malaysia.
As a conclusion,baby dumping is morally and physically wrong. Teenagers should keep a distance from crimes. They have to learn to be responsible for what they have done and think maturely on the pros and cons before jumping to a conclusion. They should be able to differentiate what is good what is bad. All in all, parents and schools must play their roles in fighting baby dumping cases by imposing enough sex education for their children and always beware on their children's actions. We should put a stop on baby dumping and start to see these infants as gifts to be treasured. After all, they are your own inheritor.



We would like to share a video with you about baby dumping. :)

IMPOLITENESS

First of all,what do you know about the meaning of impoliteness?we so sure that you did know that meaning right?Okay,impoliteness is A discourteous manner that ignores accepeted social usage.
There are a picture that show the examples of IMPOLITENESS in our life.

Next,impoliteness is synonyms with this word which is it has a same meaning of it.For Example :-
Have you ever heard about "IMPOLITENESS AMONG YOUTH".There a lot of problems that youth nowadays have a bad habits such as being rude to their teachers and others.We think this problems occur because lack of discipline from parents. An early education is the main pillar in shaping a person’s personality where the role of parents in educating their children need tobe concerned. A child will know how to choose a good friend when his parents have already taught him to do so. Although the choosing good friends sort of thing seems to be not so important but friends are one of the main elements that will give a big influence after the early education.Parents should be a good teachers for their childrens.


After that, friends are one of the factors. Why friends? Because friends are the closest people once the teenagers leave their houses. Therefore, they give a big impact of influence. Thenature of most teenagers today is that they tend to follow the trends of surroundings which means mimicking their friend’s attitude. A teenager is driven to go to the ‘masjid’ to perform prayers if the majority of his friends like to do so. Such positive influence are totally good but what need to be concerned is the negative influence which are also spreading wider and wider over the years.As mentioned before, early education is really crucial to ensure whether a teenager will choose good friends or they can evaluate which is good and which is not through their surroundings observation. Some people say, to determine a person whether he is good or bad, look at his closest friends which also being used nowadays to find a life-partner. So, be wise in choosing your best friends because it will determine your future.


Next,technology also is the main factors why the behaviour of impoliteness among us become worst time by time.Cell phones and digital communication in general have completely changed the way people interact. Youth are so attached to their gadgets rather than learn acceptable social skills. Children devote an average of seven hours and 38 minutes to entertainment media each day and 66 percent of those youth own cell phones. With less human talk time, youth aren't learning how to interact in the actual world. Not only does technology limit face-to-face time, but it also has increased the amount of communication people have. The Internet and cell phones have let all impolite evils infiltrate the once polite, isolated culture.Therefore, the media needs to pay a lot more attention to what they are showing in their programs becausewhether they realize it or not, indirectly they may turn the future generations into monsters.


Finally, a solid strategy in spreading awareness must be constructed among the community to make sure the next generation will get a better future. Everybody needs to play their role in establishing a harmonious community doesn't matter whether they are parents, teachers, media or even the governments. This can easily be achieved when everybody works together by putting aside their differences and interests on materialistic things. Come on and lets join us to fight impoliteness to restore back our humanity values in our hearts.

WORLD POVERTY

In this era of globalisation,there's a lot of problem that always had in all of the countries in the world which is poverty in the community.UNICEF stated that "21,000 people die every day of hunger or hunger-related causes, according to the United Nations. This is one person every four seconds, as you can see on this display. Sadly, it is children who die most often".Its a big problems to all of us and this problem need to be solved as soon as possible otherwise it will make complicated.
Next,we had found the latest percentage of people in the world at different levels from 2005



More than 80 percent of the world population lives in countries where income  diffrentials are widing.There are effective programs to break this spiral. For adults, there are “food for work” programs where the adults are paid with food to build schools, dig wells, make roads, and so on. This both nourishes them and builds infrastructure to end the poverty. For children, there are “food for education” programs where the children are provided with food when they attend school. Their education will help them to escape from hunger and global poverty.As a human,we need to more concern about this problems and give a donation like money and clothes to show our attention.Here are some picture we found in the internet at Manila.Philipines 
Rises in the costs of living making poor people less able to afford items. Poor people spend a greater portion of their budgets on food than richer people. As a result, poor households and those near the poverty threshold can be particularly vulnerable to increases in food prices.The World Bank warned that 100 million people were at risk of sinking deeper into poverty and its at the warning state to the people around the world.

Next,the world poverty problems right now is housing.many people at the Bangladesh live in poor condition and some of their people did not have house.As a prove here a picture to show their daily life with no house.

Such a sad moment when we see this picture.The children in our country live in good condition while at Bangladesh, their kids are very poor and live an unhealthy lifestyle because they cannot find any food to eat.


In the developing world, there is a pattern of inequality caused by the powerful subjugating the poor and keeping them dependent. Outside influence is often a large factor and access to trade and resources is the usual cause. It is often asked why the people of these countries do not stand up for themselves. In most cases when they do, they face incredible and often violent oppression from their ruling elites and from outsiders who see their national interests threatened.


Consider the following words from the United Nations:

Lastly,the steps to control the poverty in the world is 
  • Controlling overpopulation

Some argue that overpopulation and lack of access to birth control leads to population increase to exceed food production and other resource.Better education for both men and women, and more control of their lives, reduces population growth due to family planning.
  • Increasing personal income

The following are strategies used or proposed to increase personal incomes among the poor. Raising farm incomes is described as the core of the antipoverty effort as three quarters of the poor today are farmersEstimates show that growth in the agricultural productivity of small farmers is, on average, at least twice as effective in benefiting the poorest half of a country’s population as growth generated in nonagricultural sectors.

  • Increasing the supply of basic needs

Food and other goods

Agricultural technologies such as nitrogen fertilizers, pesticides and new irrigation methods have dramatically reduced food shortages in modern times by boosting yields past previous constraints. Before the Industrial Revolution, poverty had been mostly accepted as inevitable as economies produced little, making wealth scarce.Geoffrey Parker wrote that "In Antwerp and Lyon, two of the largest cities in western Europe, by 1600 three-quarters of the total population were too poor to pay taxes, and therefore likely to need relief in times of crisisThe initial industrial revolution led to high economic growth and eliminated mass absolute poverty in what is now considered the developed worldMass production of goods in places such as rapidly industrializing China has made what were once considered luxuries, such as vehicles and computers, inexpensive and thus accessible to many who were otherwise too poor to afford them.Even with new products, such as better seeds, or greater volumes of them, such as industrial production, the poor still require access to these products. Improving road and transportation infrastructure helps solve this major bottleneck. In Africa, it costs more to move fertilizer from an African seaport 60 miles inland than to ship it from the United States to Africa because of sparse, low quality roads, leading to fertilizer costs two to six times the world average.Microfranchising models such as door to door businesses are used to sell basic needs to remote areas for below market prices

  • Education
Research has found that there is a high risk of educational underachievement for children who are from low-income housing circumstances. This is often a process that begins in primary school for some less fortunate children. Instruction in the US educational system, as well as in most other countries, tends to be geared towards those students who come from more advantaged backgrounds. As a result, children in poverty are at a higher risk than advantaged children for retention in their grade, special deleterious placements during the school's hours and even not completing their high school education.

As a conclusion,world poverty can be solved properly if the government is clever on brings their countrie in good condition to their society.
