The Pros And Cons Of Pu-239

774 Words4 Pages

Humans create waste that the Earth cannot recycle quickly, if ever at all. One such product is the plutonium made at the Manhattan Project Hanford Site in what is now known as the Tri-Cities (Richland, Pasco, and Kennewick) area of Washington State. Plutonium 239 is a man-made radioactive chemical created for the plutonium bomb used on Nagasaki, Japan on August 9, 1945 to help end World War II. Plutonium 239 (Pu-239) is ”the ninety-fourth element in Mendeleyev's periodic table, is an artificial radioactive nucleus produced in large quantities by reactors when nuclei of uranium 238 capture an extra neutron apiece” (Plutonium 239). Also, “Pu-239 has a half-life of 24,100 years” (Backgrounder on Plutonium), meaning that it will take over 240,000 …show more content…

The Hanford site actively operated for over four decades. The site has 177 underground containment tanks that hold millions of gallons of high-level radioactive waste that is a result of the production of Pu-239. In 1987, Westinghouse Hanford Company, responsible for the cleanup of the nuclear waste-storage, discovered a problem with one of the tanks known as 101-SY. The tank should have been regularly venting low levels of hydrogen gas that would have been non-flammable. However, the hydrogen gas was building up in the tank. When the tank did vent, it was releasing flammable levels of hydrogen gas. This became a big concern because if a spark occurred at the time the tank was venting and ignited the gases, the chemical reaction it would cause, could release the nuclear waste into the environment. Scientists and Engineers researched and studied the tank and it’s contents along with devising a plan to solve the issue. They designed and installed a new pump which is still being monitored (Valenti, 1993). Even though the Department of Energy has possibly found a solution for this problem, there are still other environmental concerns with storing the waste, such as tanks corroding and …show more content…

The damage that would be done if this high-level nuclear waste leaked from the tanks into the ground and seeped into the Columbia River would be extremely detrimental and irreparable. “The waste is stored in large carbon steel tanks that were constructed between 1943 and 1986” (Beavers) that are buried underground. There are 149 single-shell tanks (SST’s) that were built between 1943 to 1964 and there are 28 double-shell tanks (DST’s) that were built between 1968 to 1986. As of 2014, an estimated 67 SST’s are suspected to be leaking and that about 750,000 gallons of waste leaked into the vadose zone, which is the land area that lays atop the Aquifer (Beavers). This should be of great concern to not only the residents of the Tri-Cities and Washington State, but to both the nation and the world. The Hanford site contains about two thirds of the nation’s high-level nuclear waste and the containment tanks are only meant to hold this waste for a temporary amount of time. I majority of the tanks still being used have already exceeded their intended lifespan. All this means that more tanks will corrode and leak. It is only a matter of time before more leaks occur from other tanks and if it has not happened yet, this high-level nuclear waste will seep into the Columbia River and end up in the Pacific Ocean. The global problem with this is amplified by the fact that the lifespan of these

Chapter 4 describes the horrific consequences of pre-1991 landfills. Humes writes, “Trash, sometimes with hazardous chemical waste mixed in, had been buried carelessly all over the country for decades without installing plastic barriers and other protections now deemed essential to containing landfill pollution”( 2013 p.92). Humes describes a tragic incidence near Niagara Falls, New Jersey in the 1970s. “In the 1950s, there was a residential community near Niagara Falls in New York. The community was built on what had been at one time a toxic chemical disposal site” (Humes, 2013, p.92).

When the nuclei of Uranium-235 and Plutonium-239 undergo nuclear fission, they produce waste as a by-product, which is known as nuclear waste or “fission fragments”. (Leslie Corrice, 2015) This waste contains radioisotopes, which are radioactive isotopes that have long half-lives. This means that the radioisotopes are able to stay in the atmosphere for hundreds of thousands of years, which is extremely hazardous to the earth’s environment. Very commonly this waste contaminates water and ruins the quality of both air and soil, which in turn devastates the planet.

Expected Cause The expected cause of the explosion was said to be vapor space of acrylonitrile tank 80 following a strike from “St Elmo’s fire” which entered through the pressure relief valve that is located at the top of the tanks. At the time of the explosion they had Acrylonitrile being pumped into tank 80. Eye witnesses said it was bad weather that caused lightning rather than malpractice; but there was no one that actually saw the tanks being hit by

During the better part of 1940, part of industrial Denver, CO, was home to a chemical weapon manufacturer for the World War II effort. The manufacturer, The Rocky Mountain Arsenal, continued operations beyond the war, and their waste disposal practices led to the contamination of many natural resources until it finally ceased all activity in 1982. In 1987, RMA was placed in the National Priorities List, a series of US toxic waste sites that would need long-term cleanup to be funded by the federal government’s Superfund initiative.

1 The Deepwater Horizon was a drilling rig, which had been rented by British Petroleum (BP), in the Gulf of Mexico. The rig exploded on April 20th, 2010, pouring nearly 5 million barrels of oil into the sea over a three months’ span. This environmental crisis endangered marine wildlife, as well as workers that were injured during the explosion. Of 126 people, 28 workers in total were hurt, leaving 11 that were fatally injured, while the other 17 were severely injured (Crandall, Parnell, & Spillan, 2013).

In Richard Muller’s essay on Chemical Waste in America, he points out many different problems in todays disposal techniques of nuclear waste. He brings in readers by appealing to American citizens with his visual texts, guilt, and how we must start feeling some empathy for our future generations and find a solution to prevent a massive chemical waste epidemic. Mullers argument bases off his visual texts, by showing us a reality that is going on today. Among the visual texts, Muller explains the exact quantity of chemical wastes in the United States by telling his audience that, “we have already generated more than enough nuclear waste to fill up Yucca Mountain,” which is a storage bunker for chemical waste products. Muller even includes a picture of Yucca Mountain so the audience can get a feel for the absurd amount of waste we have built up.

Groundwater contamination has been documented at 13 of North Carolina’s coal-fired power plants (“Energy-Related”). Even after wildlife advocates exposed the damage to aquatic habitats from the Dan River ash spill, Duke Energy and politicians only contemplated the state of human life rather than biological life. Although no human deaths resulted from the Dan River spill, increased

In 1939, the world’s most scientific community found out physicists from Germany learned how to split the uranium atom. Albert Einstein and Enrico Fermi fled from the Nazis and Italy are now living in the United States. They both agreed to inform the president of the dangers of atomic production, and Roosevelt agreed to proceed slowly to make an atom bomb. Late 1941, America received the code name the “Manhattan Project” for the designing of the atom bomb. The atom bomb cost $5 Billion to make during the WWII era.

This intrigued me, because the thought of something so small having an impact so large, it’s just so implausible. being the son of a scientist's, I started to snoop around. I unearthed a piece of plutonium from the Harvard University. This is what the Harvard research paper said: “Plutonium-239 is one of the two fissile materials used for the production of nuclear weapons and in some nuclear reactors as a source of energy. The other fissile material is uranium-235.

The bombing of Pearl Harbor convinced Roosevelt that more had to be done on the atomic research. By the end of 1942, bomb research had become bomb production, Manhattan Project was ran by the military with Major Leslie Groves as officer in charge. Bomb production was carried out in three locations, Oak Ridge Tennessee handled production of the bomb fuel U-235, Hanford Washington handled production of plutonium fuel, and Los Alamos New Mexico handled bomb production and assembly. These three locations became huge cities due to size of and manpower required for this project. Once the project was at a larger scale the work in factories and producing the atomic weapons employed over 130,000 people.

(Chavan, 2016). The area that would be affected if this did happen would not be inhabitable for a very long time because the half-life for the plutonium that would be released is 24000 years, this plutonium is very toxic and will cause cancer if only a tiny bit is inhaled. The cost of making a FBR is very high so the reactor would have to be operating for a very long time to make as much money as they take to build. The plutonium can also be made into nuclear weapons so they could be sabotaged by terrorist’s and used as

The Manhattan Project was an impressive, secret, wartime effort to design and build the world’s first nuclear weapon, at the hands of some of the world’s greatest physicists and mathematicians. This development was a $20 billion project during World War II that eventually resulted in the first production of uranium and plutonium bombs. Driven by the fear that Hitler’s Germany would invent the bomb first, America’s quest for nuclear explosives took less than four years and took place in facilities at Oak Ridge, Tennessee and Hanford, Washington. In this thesis paper, we will look at the history of how the Manhattan Project came to be and the scientific and technology aspects of building the atomic bomb. As well as the different methods in achieving this major milestone in human history 1 The History of the Manhattan Project

The head of this lab was Robert Oppenheimer, a famous individual in the story of the first atomic bomb. At this facility, thousands of workers assembled the device with plans to test it there. On July 16th, the plan was executed when the world's first atomic bomb was tested in the New Mexico desert. It yielded roughly 20 kilotons of explosive power and created a crater that was 10 feet deep and 1,000 feet wide. (Atomic Heritage Foundation)
