1) Site/Situation History & Background (Fort MacMurray, Alberta) Nuclear power is a clean fuel, which results in little waste. In comparison with the traditional way of power generation, nuclear power is low-emission and high-efficiency in addition to being a carbon-free method of generating electricity. In this assessment, we are trying to figure out the contaminant sources of the nuclear power plant. The biggest threat for human’s health is the radioactivity of the chemicals which are being used to created power. Generally speaking, the radioactivity usually comes from the waste of the nuclear power plant, which is created during the nuclear reprocessing. Based on the intensity of these chemicals, they are separated into 3 levels: 1. High-level waste 2. Intermediate-level waste 3. Low-level waste One thing must be clearly pointed out is the radioactivity comes from the waste is the most harmful to health, which is why observations about this area are of high importance. In this case, we decided to focus on the high-level waste since it has the most adverse impacts on humans and the environment. Radioactivity will decrease with the increase of time. The traditional method of storing waste is burying underground until it doesn’t pose a threat to human and environmental health. We decided to choose uranium as the representative to finish this risk assessment since it is one of the most important chemical for nuclear power plant to create energy. 2) Chemical of Concern…

Three Mile Island Accident Introduction Radioactive reactants are one of the leading source of electricity in our country thus making it very important to us. Radioactive compounds that are used to run the nuclear reactor's turbines by heating water into steam which run generators to produce electricity though are a dangerous hazard to us. There have been many nuclear plants accidents in our country, but the Three Mile Island accident is one of the most significant regarding hazard management…

Nuclear Energy - Environment’s rejuvenation or a hazard!! In the early 1930s and 1940s, research was at its pinnacle yet very ‘small’, small in size, not in size of work but in size of the subject- atoms, neutrons, protons and nuclei. The works of Rutherford, Bohr, Einstein, Chadwick, Curie, Frederic, Fermi, Hahn, Strassmann all eventually led to the discovery of Nuclear Power or Energy, which is believed to be the panacea of energy crises that currently exist. It is a boon to the modern…

Simply by hearing the word nuclear people immediately steer away from the topic or dismiss it entirely. The word is tied to death and destruction but over all else fear. We think of the atomic bombs the U.S. dropped on Japan. We think of Chernobyl, Three Mile Island, and most recently Fukishima. All three melted down leaving destruction and untold consequences in their wake. Although these events were indeed disasters, they were cause by unknown factors and were the worst case scenario; Yet…

The disadvantages of nuclear energy are; national risk, environment problems and negative effect one human life. The first reasons why nuclear energy is a disadvantage for people is that it poses a national risk. There are many factors in life that may cause national risk. One of big factors which can play a big part in national risk. Nuclear products many factors to make life better, but people also use it to produce many dangerous materials; for example, weapons that are a threat to human life…

1. “Why the World May Turn to Nuclear Power” is a passage that lays out all of the main components of Nuclear energy. It is filled with statistics and real world examples, including visual aids. The major purpose of this text is to inform the reader that nuclear power is in fact a beneficial form of energy. Three images on page 18 show nuclear power in action. The bottom right picture illustrates a woman repowering her Nissan LEAF car with the help of nuclear energy. The authors tell us that…

The two sides are debating the support or fear of nuclear power plants. After the events at Fukushima, the earthquake and tsunami, the power plant sickened a lot of people due to its radiation. Professor George Monbiot and Melissa Block discuss the opinion to support nuclear power plants. He states that if so many people can die or become injured due to mining, then how is that any different than people dying or becoming sick from nuclear waste radiation? He said that coal was a bigger issue…

“I am become death, destroyer of worlds.” These famous words were uttered by the J. Robert Oppenheimer - creator of the atomic bomb - at its first test in 1945. A few months later, two bombs were dropped onto Hiroshima and Nagasaki, and the world was changed forever. Now, over 70 years later, we are using this same destructive power, but we are using it for supposedly peaceful and harmless purposes, such as creating electricity by splitting the atom. We seem to have forgotten what this power was…

We as humans are expending our fossil fuels at an alarming rate. By 2088 we will have completely run out of options for using fossil fuels for electricity (The End of Fossil Fuels). As the resources slowly diminish, people are looking for an alternative source to create electricity for both heat and light. This seems to be particularly true in the United States, where the government wants to not rely on the petroleum from countries in the Middle East. The idea is good, however the focus is less…

The use of nuclear power has been under debate for many years; with issues such as environmental impact, safety, cost, waste management, and efficiency, the cons clearly outweigh the pros. Nuclear power plants have been supplying electricity to the population for nearly 60 years, but all things must come to an end as better options emerge and humanity develops as a species. It 's only natural for things to become outdated, or be replaced by better options as they become available. Nuclear…
