As populations grow, countries develop and industries boom, demand for energy continues to increase. Many countries see nuclear power as a way of meeting their electricity needs while reducing their CO2 emissions. There are many misconceptions in society about nuclear power. While it may be dangerous, nuclear can solve the energy demand for a country’s growing population, particularly Australia. The truth behind nuclear physics will be discussed in this report, the types of nuclear radiations and its effects, the enormous amount of energy a nuclear reaction can produce, the developments of nuclear generators, along with suggestions for Australia regarding the development of nuclear power plant in the country. 1. The Consequences of Nuclear …show more content…
Some would interact with the body, so they are dangerous, but most would get straight out and make the body itself the source of radiation to the surrounding environment. On April 26th 1986, the world’s worst nuclear accident occurred at the Chernobyl Nuclear Power Plant in Ukraine. The explosion sent a ‘cloud of radiation’ throughout the area, including Belarus, and much of the western Soviet Union and Europe, releasing 400 times more than the atomic bombing of Hiroshima. This is because a nuclear power plant contains a lot more nuclear material than an atomic bomb. In the Chernobyl meltdown, most of the exploding was due to containment failure and explosions from steam build-up. The meltdown has produced a far higher amount of radioactive materials, because fission explosion at ground level creates more radioactive isotopes due to neutron activation in soil. Furthermore, the half-lives of the isotopes made in the Chernobyl accident are longer. Having more fissionable material increases the amount of radiation that can be produced as well as the amount of radioactive …show more content…
Nuclear Fusion is a process where small nuclei can combine to make a larger nucleus. This is permitted when the binding energy per nucleon of the product is higher. The difference in mass/energy is released. The most common fusion reaction occurs in stars, involving two hydrogen isotopes, deuterium and tritium. First, two hydrogen atoms split to produce deuterium, an electron and energy: The deuterium will then fuse with a hydrogen atom to produce helium-3 and gamma waves: Two of the helium-3 produced will then split to produce helium-4, two hydrogen atoms and gamma waves: The theory behind nuclear fusion and fission is from the famous mass-energy equivalence formula by Einstein, E=mc2. According to E=mc2, energy and mass are interchangeable. The value of the square of the speed of light c2 is very big. Just a small change of the mass m affects greatly in the energy E. Therefore, the small amounts lost mass during fusion or fission translates into a very big amount of
The engineers in Visit Sunny Chernobyl created a new frontier past the safety zone because they want to test the limits of the reactor. What the scientists didn’t account for is that fact that the reactors already had the potential of a dangerous chain reaction. (Blackwell 6) Consequently, their boundary destroying led to catastrophic consequences and the total annihilation of a land area because of massive radiation. Blackwell thought Chernobyl was so horrific he expressed that no one should visit without a “working understanding of radiation and how it’s measured” (Blackwell 7). These are some horrific consequences that followed from surpassing the
When the released neutrons attach to other isotopes of Uranium 235, this can result in a chain reaction of fission. For every generation of fission, the amount of fission is doubled, and this results in an extreme outburst of energy. The amount of energy released by this process is related to Einstein’s famous equation “E=mc2” (Wolf). Einstein's equation "E=mc2" has two sides, which are constructive and destructive. The constructive side is when energy is converted into mass, and the destructive side is when a small amount of mass is converted into energy.
All these effects were the cause of the discovery of nuclear fission and its properties. Nuclear Fusion Nuclear fusion is the process used by the sun and the stars in our solar system to produce their energy. Fusion involves smashing hydrogen atoms together at high velocities to form helium, and the matter is made into energy.
On April 26th, 1986, operators at the Chernobyl Power Plant in Chernobyl, Ukraine, ran what they thought to be a routine safety test. But fate was not on the side of these operators. Without warning, reactor #4 became unstable, as it had been operating at a low power for a possible shutdown and the reactor’s design caused it to be unsafe at this level of power. Internal temperatures rose. Attempts to cool the system produced the opposite effect. Instantly, the nuclear core surged with power. At 1:23 p.m., the reactor exploded. The first blast ripped off the reactor's steel roof. The second blast released a large plume of radiation into the sky. Flames engulfed the building. For ten long days, fire fighters and power plant workers attempted to overcome the inferno. Thirty-one of them died of radiation poisoning. Chernobyl was the worst nuclear disaster in history. It unleashed radiation hundreds of times greater than the atomic bombs exploded over Japan during World War II. [1]
Nuclear energy must be a consideration for the future with the rapidly depleting supply of fossil fuels. This type of energy can be created through nuclear fission and nuclear fusion. Nuclear fission is the splitting of a heavy atom into two or more parts, releasing huge amounts of energy. The release of energy can be controlled and captured for generating electricity. Nuclear fusion involves bombarding hydrogen atoms together to form helium. In the long run, nuclear fusion has greater potential than fission.
Hopefully, with accurate analysis and innovation, my research will teach the world of its past so this disaster doesn’t occur in the future. B - Summary of Evidence Chernobyl (chrn byl) is an uninhibited city in north Ukraine, near the Belarus boundary, on the Pripyat River. Ten miles to the north, in the town of Pripyat, is the Chernobyl nuclear powerstation, site of the worst nuclear reactor disaster in history ("Chernobyl", Columbia Encyclopedia). To specify, on April 26, 1986, Unit Four of the Chernobyl nuclear reactor exploded in Ukraine, injuring human immune systems and the genetic structure of cells, contaminating soils and waterways. Nearly 7 tons of irradiated reactor fuel was released into the environment—roughly 340 million curies.
Chernobyl was the greatest nuclear disaster of the 20th century. On April 26th, 1986, one of four nuclear reactors located in the Soviet Union melted down and contaminated a vast area of Eastern Europe. The meltdown, a result of human error, lapsed safety precautions, and lack of a containment vessel, was barely contained by dropping sand and releasing huge amounts of deadly radioactive isotopes into the atmosphere. The resulting contamination killed or injured hundreds of thousands of people and devastated the environment. The affects of this accident are still being felt today and will be felt for generations to come.
Nuclear energy is produced during the process named nuclear fission or nuclear fusion. The development of nuclear energy started in the 20th century and there is now worldwide recognition for using nuclear energy. Popular countries that operates nuclear power are United States, France, Japan, and Russia, the nuclear energy generates up to 6% of the world’s electricity supplies. Even though the energy is mostly used by many countries, but it may causes side effect to the living things in the environment. (WNA, 2012)
"The tops are leaping off the reactor lip" this was the first warning which the control room received before the destructive explosion in Chernobyl that occurred at 1:23 AM local time. Twenty three minute after the warning in the morning of 26 April 1989, the reactor exploded. The Chernobyl nuclear accident was an unexpected catastrophe that can happen in the history of producing nuclear power. International Atomic Energy Agency (IAEA) defined a nuclear accident as an accident that includes any activities that lead to the release of radioactive material and causes significant consequences. The location of Chernobyl city is in the north of Ukraine near the Belarus border. That nuclear accident happened when in reactor number 4 in the Chernobyl nuclear power in the Soviet Union exploded. Because of that extreme explosion, the radioactive emissions dispensed into the environment and caused immediate deaths, illnesses and many health problems. World Health Association (2013) reports that during the accident, one person died immediately and another one died in the hospital due to the harmful injuries he received. Health World Organization (WHO) (2006) also reports that a few weeks after the disaster 28 people died because of the Acute Radiation Sickness(ARS). The Chernobyl nuclear accident is one of the major disasters in the history of nuclear power which had many serious effects on humans and the environment.
Energy is created in a fusion reaction through the loss of atomic mass from the beginning to the end of the reaction. The mass of the two atoms is significantly more than the mass of the new atom, which they fused together to form. This loss of mass is subsequently converted into pure energy in the form of light and heat. The reason for this amazing discovery is that mass is just a concentrated form of energy. This understanding between the relationship of mass and energy was discovered by Albert Einstein and illustrated in his famous equation E=mc^2, where E is energy, m is mass, and c is the speed of light. Through this equation the amount of energy held within a mass can be determined. In a plasma fusion reaction between two hydrogen atoms the decrease in mass is about 4x10^-29 kg. This mass is then converted to energy, equaling 23.9 MeV. "To appreciate the magnitude of this result note that if 1g of [hydrogen] is converted to helium, the energy released… would be worth about $70,000" (Physics for scientist and Engineers 1276).
Alpha radiation/emission - Alpha particles are the nuclei of a Helium atom 42He. Consisting of two protons and two neutrons, positively charged.

One of the most significant environmentally damaging instances in history was the Chernobyl incident. In 1986, the Chernobyl Nuclear Plant in Ukraine exploded. It became one of the most significant disasters in the engineering community. There are different factors that contributed to the disaster. The personnel that were tasked with operating the plant were unqualified. The plant’s design was a complex one. The RBMK reactor was Soviet design, and the staff had not be acquainted with this particular design. As the operators performed tests on the reactor, they disabled the automatic shutdown mechanism. After the test, the attempt to shut down the reactor was unsuccessful as it was unstable. This is the immediate cause of the Chernobyl Accident. It later became the most significant nuclear disaster in the history of the
Nuclear fusion occurs when two atomic nuclei collide with enough energy to bind together to form one nucleus. Nuclear fusion occurs in the core of our sun, and is the source of its tremendous heat. In the sun hydrogen nuclei, single protons, fuse together and form a new nucleus. In the conversion, a small amount of mass is converted into energy. It is this energy that heats the sun.
Nuclear energy is generated by a process called fission. Fission occurs within the reactor of a nuclear power plant when a neutron is fired at an atom of uranium causing it to split and release subsequent neutrons.1 These are able to crash into other uranium atoms causing a chain reaction and releasing a great deal of heat energy.
