I believe that Three Mile Island needs to stay open. Nuclear Power Opinion Paper-Three Mile Island: Rough Copy Three Mile Island (TMI) is a nuclear power plant located in Harrisburg, Pennsylvania, running since 1974. In 2019, the Exelon Corporation plans to shut down Three Mile Island, an essential role in the economy that produces a large amount of Pennsylvania's electricity. This is because because they haven’t been profitable for the past 5 years, and have lost more than $300…

Ordinary Portland cement (OPC) has been commonly used in many countries for centuries. It is relatively easy to get OPC into an active binder, as it is a common practice due to its wide availability and it being economically friendly. This may seem like perfect cement. However, OPC has a significant impact on the environment caused by the CO2 emitted during the process of manufacture, which plays a big role in the increase of greenhouse gases. Therefore, a more sustainable option has to be…

CONSERVE FOSSIL FUELS The climate change is a hard situation and a big problem. Everybody is informed about the climate change, everybody knows how climate changes affect our planet, the people and our nature and environment. The biggest reason why we have climate change is because we use fossil fuels. I live an ordinary life, I go to school, I have friends and a good family. Today the majority of people in the world live a good life, we have money and we have food on our table. But how can…

(1) Basic Substance. The basic substance used to make both steel and cast iron (gray and malleable) is the metal, iron in the form of pig iron. Pig iron is produced from iron ore, which occurs chiefly in nature as an oxide, the two most important oxides being hematite and magnetite. (2) Iron Ore. Iron ore is reduced to pig iron in a blast furnace, and the impurities are removed in the form of slag (figure 2 on the following page). Raw materials charged into the furnace include iron ore, coke,…

Joseph Gore Thermal Imaging Cameras (TIC) in the Fire Service The fire service, as we know it today, has come a long way since its beginning. It began in 24 BC in Rome. One of the first technologies used were a line of men and a few buckets of water, which were used to extinguish the fire. Another of the first technologies was an axe that was used to create holes that would allow heat and smoke to escape from the structure. Compared to the ancient times, today’s technologies have improved…

Why Fossil Fuels Should Not be Banned Envision a situation in the fossil fuel industry, however, everyone lost their jobs due to the fact that fossil fuels were banned? Debate on whether or not fossil fuels should be banned is vivid, it should not at all banned. A variety of people condone that non-renewable energy is just unmistakably unacceptable since it releases greenhouse gases that are nasty for the environment with other demerits. Nevertheless, without practical or feasible…

Shearon Harris Nuclear Power Plant is located 20 miles southwest of Raleigh, NC. It is a 900 megawatt facility, which provided energy to 550,000 households. Enriched uranium (uranium dioxide pellets) is used as the fuel in the plant, which is 2-3% uranium 235. Cooling is necessary and the plant uses 800-2,600 gallons of water per megawatt hour. U-235 will decay into U-238, which is the primary waste product. Please see the PhET Simulations website for multiple simulations about nuclear…

The crash box is the car component that is attached at each end of a car’s bumper and its function is to absorb the energy produced during collision or impact. Chapter 1 describes briefly on crash boxes and their characteristics. As mentioned earlier in Chapter 1, crash boxes are designed with or without patterns. Each one of the designs have different energy absorbing characteristic depending on the design and its patterns, shape, size, etc. Most crash boxes are designed with several grooves…

Heat Recovery Steam Generator is a part of a power plant, which generates steam. The heat recovery steam generator used a gas turbine to operate, by using the flue (gas) from the exhaust of the gas turbine Figure 1. The heat exchanges process occurs between the boiler and exhaust gas, which is used to heat water in a boiler to raise the pressure of the steam. [1] In addition, the gas turbine is used for power source due to it has some advantages such as can be started quickly, can be easily…

I am all for renewable resources. I also strongly agree that natural gas is our way to wean off coal and slowly enter into renewable energy sources. I would just like to compare how natural gas can still win over renewable resources in one aspect. Let’s take a look at wind energy. As a renewable energy source, wind energy requires an immense amount…
