    Everyone, watch Time Warp on Youtube!

    Here is the video which I guess is what Mdm Tan said in class just now.

    Q1.What is Nuclear Energy?

    Nuclear energy originates from the splitting of uranium atoms in a process called fission. At the power plant, the fission process is used to generate heat for producing steam, which is used by a turbine to generate electricity.

    Q2.The advantages of nuclear power:

    *The advantages of nuclear power include:
    Uranium is an abundant source of concentrated energy which does not release any greenhouse gas emissions. Since uranium is used as the main fuel, nuclear power plants do not contribute to higher carbon dioxide levels and global warming. Worldwide nuclear energy avoids on average the emission of more than two billion metric tonnes of carbon dioxide per year. Although nuclear power reactors are expensive to build, they are relatively cheap to operate. At about two parts per million in the earth’s crust, uranium is similar in abundance to gold, silver and mercury, however, quite small quantities are required for a large power station.

    *The disadvantages to the use of nuclear energy include:
    Uranium is a non-renewable energy source because uranium supplies are limited and they draw on finite resources that will eventually dwindle.
    Uranium and its by-products from the use in reactors are highly radioactive. The phenomenon of radioactivity was discovered by French physicist Henri Becquerel in 1896 when he noticed an exposure effect on a photographic plate stored in a drawer next to a rock that contained uranium. Soon afterwards, another French scientist, Marie Curie - who was working to understand uranium and its by-products – discovered two new elements, radium and polonium. Curie was to eventually die from the effects of radiation exposure. We now know that radioactive elements can seriously affect human health and this remains the major concern of people opposed to the use of nuclear power.

    Q3.Is Nuclear energy commented in Singapore?

    Led by Finance Minister Tharman Shanmugaratnam, the Economic Strategies Committee (ESC) in unveiling its ambitious plans for Singapore’s economic transformation suggested the feasibility of using nuclear energy to meet the base load electricity demand and ensure Singapore’s energy security in the long run.
    The government of Singapore should seriously consider if nuclear energy is something that is suitable for a country like Singapore.
    The cost of launching a nuclear power reactor from the ground up is too slow and expensive a process. And the World Information Service on Energy has rightly pointed out that when factors like construction, extraction, treatment, conversion, transport and stocking of waste are taken into account, the nuclear sector’s CO2 emissions are far from negligible.
    It takes many years to build a nuclear reactor and the billions of dollars of investment needed to build the nuclear reactors would create twice the amount of carbon pollution in that time frame. And what’s more important is that it takes away the resources needed to implement meaningful climate change proposals.
    Patrick Moore, a prominent environmentalist, said in his 1976 Greenpeace Report that “Nuclear power plants are, next to nuclear warheads themselves, the most dangerous devices that man has ever created. Their construction and proliferation is the most irresponsible, in fact the most criminal, act ever to have taken place on this planet.”In November 2000, the United Nations Climate Change talks in The Hague refused to give nuclear energy greenhouse gas credits, recognizing it for what it was: a dirty, dangerous and unnecessary technology.
    Nuclear power was dealt a further blow when a United Nations Sustainable Development Conference refused to label nuclear energy a sustainable technology in April 2001.

    Dear Yumi,

    My name is Adrian Au and I am from Singapore. I

    am a Chinese boy and my birthday is on the 19th

    of June, 1993. I am fairly good-looking boy and

    I have dark hair. I am tall and slim. I wonder

    how you look like. You must be a beautiful fair

    young Japanese girl. When I have free time, I

    like to play video games, occasionally

    rollerblading and swimming. One subject I hate

    is Chinese as I hate memorizing Chinese

    characters and therefore Chinese is my worst

    subject. I am curious how many members there are

    in your family. My family members consists of my

    mum, dad, sister Sandy, dog Ash ad hamster Bob.

    You can learn more about me and my pets by

    visiting my homepage at www.adrian.au.com. I

    want a Japanese pen pal as I want to learn about

    other countries and to make new friends. I hope

    you can write soon and I look forward to your

    reply.

    Your friend,
    Adrian Au
