First we need to find out now a Nuclear Power plant works....
There're two types of Nuclear reactors: The Boiling water reactor below..
where the water heated by fission actually boils and turns into steam to turn the generator..
And the Pressurised water reactor..
where they keep water under pressure so that it heats but does not boil. Water from the reactor and the water that is turned into steam are in separate pipes and never mix.Since the fission process creates radioactivity, all nuclear power plants must have many safety systems that protect workers, the public and the environment. For example, systems allow the fission process to be stopped and the reactor to be shut down quickly. Other systems cool the reactor and carry heat away from it or barriers to keep the radioactivity from escaping into the environment.
In reactors, radiation is contained inside small ceramic pellets about the size of an adult's finger. They are placed in long metal rods inside a reactor vessel, which is enclosed in a concrete and steel containment building.
The Chernobyl Disaster!
-
The operating crew was planning to test whether the turbines could produce sufficient energy to keep the coolant pumps running in the event of a loss of power until the emergency diesel generator was activated.
To prevent any interruptions to the power of the reactor, the safety systems were deliberately switched off. To conduct the test, the reactor had to be powered down to 25 percent of its capacity. This procedure did not go according to plan and the reactor power level fell to less than 1 percent. The power therefore had to be slowly increased. But 30 seconds after the start of the test, there was an unexpected power surge. The reactor's emergency shutdown (which should have halted a chain reaction) failed.
The reactor's fuel elements ruptured and there was a violent explosion. The 1000-tonne sealing cap on the reactor building was blown off. At temperatures of over 2000°C, the fuel rods melted. The graphite covering of the reactor then ignited. The graphite burned for nine days, churning huge quantities of radiation into the environment. The accident released more radiation than the deliberate dropping of a nuclear bomb on Hiroshima, Japan in August 1945.
Nuclear energy is a very dangerous source of energy. Radiation caused by the atoms will affect each and everyone in Singapore as it is a small island. People will have to live miles away from nuclear power plant to be safe and there are just no space in Singapore. Even then, people would die from cancer caused by radiation.
Here are some different views from important government officials :
Just like President Obama said, even though nuclear energy does not produce greenhouse gases and is environmental friendly, we cannot ensure that the nuclear waste will be stored safely.
As a resident living in Singapore, what do you think? Shall we keep up with the latest technology and expose ourselves to inevitable incidents that will affect the whole of Singapore, or dismiss the idea and avail ourselves to different types of clean energy with regard to our safety and the future generation?
