Nuclear Energy

Nuclear Energy
Everything in life must have a beginning. It is a scientific fact. This is the same as Nuclear Energy. Nuclear energy wasn?t just discovered, it was created. Nuclear energy is the energy released by a nuclear reaction, especially by fission or fusion. From its first controlled chain reaction to be waste disposal problems, nuclear energy has made major steps. Nuclear energy began in Chicago at Stagg Field. The company that was responsible for this was Enrico Fermi. Here the company was able to create the first controlled chain reaction. The first reactors were based on natural uranium as the nuclear fuel, graphite as the moderator and water as the coolant (Prasar). This opened the floodgates for al nuclear energy. Now that we know to control the dangerous energy, we can use it without fearing drastic measures.
In 1955 underwater combat was changed forever. The first submarine, The uss Nautilus, was fueled on nuclear power. The nautilus broke all submarine records for underwater speed and endurance. It was launched in Thames River after Mamie Eisenhower smashed a bottle of champagne across the bow. Due to running on nuclear energy, this made the Nautilus able to travel for great distances at a top speed of 25 knots or more. This made the submarine a much more potent fighting craft and placed the usa a step ahead of all other countries in underwater war (Norris). Even though it was a remarkable task during the year, the navy only expected even greater submarines to come in the future. Admiral Robert B. Carney, Chief of Naval Operations commented that, ?as remarkable as this development seems to us now, the Nautilus will probably appear to our sons and grandsons as a quaint old piece of machinery which introduced the transition to a new age of power? (Norris). As the saying goes, ?You must take the good with the bad? this certainly applies with Nuclear energy. In 1957 began the first of the accidents. Over in Liverpool, England a fire erupted in a graphite-cooled reactor. This caused a 200 square mile area to become contaminated. Radiation was scattered all over the countryside. The first horrific accident has struck the world that was a result of nuclear energy. Only 19 years later, the first close call melt down had occurred. Staying in Europe, the accident occurred in Greifswalk, East Germany. A radioactive core of the reactor nearly melted due to the failure of a safety system during a fire. Thankfully not much causality occurred. Three years later though in North America, the first partial meltdown occurred. The site, Harrisburg, PA, Three Mile Island. On March 28th, one of the two reactors lost its coolant. This caused an overheating and a partial meltdown of the uranium core. Due to this, radioactive water and gases were released into the environment. Nuclear energy is beginning to be viewed negatively and dangerous. The date was April 26, 1986. The place Chernobyl, Kiev, Ukraine. This Nuclear Power Plant had four reactors. It was one of the largest plants at the time. As it usually happens an explosion and fire occurred in the graphite core in one of the reactors. This caused a leakage of radioactive material that spread over part of the Soviet Union, Eastern Europe, Scandinavia and later Western Europe. By looking on a map, you can grasp how large this accident really was. With an accident this huge, there are still repercussions today. In the Ukrainian Weekly, the author wrote, ?Chernobyl is bleeding. Seventeen years to the month after the world?s first nuclear accident, the entombing the reactor is on the verge of collapse risking the further release of radiation. Ms. Manning wrote about the accident, ?"Many of the first wave of workers who rushed to contain the explosion died within hours from the radiation pouring from the shattered reactor. To date epidemiologists place the total deaths somewhere between 15,000 and 30,000, many of which critics say could have been avoided by early safety measures. Moscow, then the capital of the Soviet Union, did not admit the accident for hours even among local populations, nor the scope of the devastation for several days. Meanwhile, people in nearby communities sunbathed and picnicked in the unusually warm spring weather around the May Day holiday, exposing themselves to the flow of radioactive particles ultimately carried by winds for hundreds of miles from the site.? This is clearly the worst accident that occurred in history of Nuclear Power Plants (Ukrainian Weekly). In conclusion nuclear energy have gone a long way since the early fifties. From controlling fusion to nuclear generated submarines to accidents, nuclear energy benefited the world greatly. Even though there have been negatives, we can?t deny that the positives outweigh the bad.
