Radioactive Waste
“Regardless of the future of nuclear power, the need to control and manage radioactive waste will persist for many decades. The objective of any radioactive waste management programme must be that undue burdens on future generations are avoided.” - Nuclear Energy Agency
Radioactive Waste
Have you seen or heard the news lately? Radioactive waste water contamination… Contracts for the disposal of radioactive waste… Nuclear sites and dumps leaking… Cancer and Death by Radiation… What is all this? More importantly what is radioactive waste?
Radioactive waste. What is it? Radioactive waste is what the name says it is; radioactive and waste. Basically, it is anything that has been exposed to a radioactive nuclear substance and is not in use of anyone anymore so it is declared as trash. Also bear in mind that any definitions or information varies in different countries. Now, there are many different types of waste, ranging from the least amount of hazard to the greatest amount of hazard. The ones with the least amount of radioactivity tend to have shorter lives. They decay in less than 30 years and are called, “short-lived”. The ones with a greater amount of radioactivity perish in more than 30 years and are called, “long-lived”. Let’s break these types of wastes into three parts. Low-level waste (LLW), Intermediate-level waste (ILW), and High-level waste (HLW).
Low-level waste are objects that we deem ‘small’ or ‘unimportant’ and have been infected with
Nuclear waste is a radioactive waste that is dangerous, and a fair percentage of people would agree on this topic. However, is it really dangerous or is it just harmful to an extent? In society, many debates are held over trying to prove to the world that this substance is harmful. In the essay, “Nuclear Waste,” Muller states clearly that he sides with the anti-nuke of the debate and how he pinpoints the facts of nuclear waste with great persuasion. Yet, it is uncertain whether Muller clearly has a good argument and/or answers the questions that many people linger to know.
• Waste from nuclear energy stays radioactive for thousands of years. Great care has to be taken in storing this waste safely.
The Institute for Energy and Environment offered and alternative in 1999 for the management of nuclear waste. For short term storage the Institute for Energy and Research (IEER) recommended nuclear waste should be stored as near and safely as possible from where it was produced. IEER suggests that the sites need to be dry and as close as possible to the place where the waste was generated to avoid a potential terrorist disaster. The funding for the extra storage on the site should come from the Federal Governments Nuclear Waste Fund.

IEER suggests that the sites need to be dry and as close as possible to the place where the waste was generated to avoid a potential terrorist disaster. The funding for the extra storage on the site should come from the Federal Governments Nuclear Waste Fund. Many repositories should be looked and studied for more than a decade and none prioritized. Finding a permanent and safe solution is very difficult and would require a lot of time because of the want for good science (Ledwidge,
Since its discovery in the late 19th century, nuclear energy has been used in a diversity of areas such as atomic bombs, medicine, reducing pollution and food irradiation (Gupta, 2012). However, one of the biggest outcomes since this discovery is nuclear energy generation. This subject is largely controversial as it has many pros and cons. It is considered to be a more eco-friendly alternative source of electricity, as it emits less carbon emissions than coal-fired power stations, for example. Yet there still an environmental risk provided by the radio-active waste and its inability to be disposed of for 100,000 years (Phillips, 2012). Today in Australia there are no active nuclear power plants but that is predicted to change in the
Disposal of the high level nuclear waste that comes from nuclear power plants continues to be a big problem. It has been challenging and costly to find safe ways to store this waste. According to a report from the U.S National Academy of Sciences, it will take 3 million years for radioactive waste stored in the U.S. as of 1983 to decay to background levels (thinkquest.org). Who wants this amount of waste stored in the environment where they live? Currently in the U.S. nuclear power plants produce 3,000 tons of this high level waste each year (thinkquest.org). If nuclear power continues to be produced, this amount of waste will only continue to increase, causing a bigger dilemma as to what to do with the waste. As the waste is removed from the plant it still contains a high level of radiation. Exposure to radiation whether it occurs in the moving process or leakage from storage not only has a negative impact on the environment but also can pose a major health threat to humans. Based on the level of exposure, symptoms to humans can range from nausea and headaches to damage of nerve cells, loss of white blood cells and even death (think .org). The potential risk of exposure is not worth human life.
There are two major categories of nuclear waste. High-level waste (HLW) and low-level waste (LLW). HLW has high amounts of radioactive materials in a small volume, and it also contains radionuclides with long half-lives .HLW is mainly composed of spent fuel and waste generated by military applications; on the other hand, LLW is generated from mining and excavation activities. [2].
Highly radioactive waste disposal has become one of the most controversial aspects of nuclear technology. As the amount of spent nuclear fuel from commercial nuclear reactors and high-level radioactive waste from defense-related processing plants has continued to mount, the issue has become increasingly contentious and politicized.2 The politicization of this issue is especially evident in the site selection process of a permanent national repository for the disposal of highly radioactive waste.
Naturally forming uranium undergoes radioactive decay by emission of an alpha particle and gamma radiation. As the decay continues, it releases radiation.This is an extreme health issue that, in large amounts, can cause cancer and liver damage.
The A simple definition of the word radioactiveis to have or develope a strong and dangerous form of energy. This could also be named radiation. A radioactive substance incvolves a very harmful form of energy that is developed betwen nuclear reactions. In the book "The Radioactive Boyscout" by ken Silversteint, there are several examples of radioactive substances being produced. The main character in the book is very as the title says "radioactive"
Nuclear waste is a by-product of the uranium enrichment process and the operation of nuclear power plants. One of the most common radioactive isotopes found in nuclear waste is plutonium-239, which is capable of causing cancer-related fatalities for millions of people in very small amounts. Other isotopes include iodine-129, cesium-137, and uranium-238, all of which are highly radioactive and have half-lives in the tens of
The primary concern when disposing of nuclear waste and cleaning the facilities that produce it is the duration of half-lives of the elements that make up nuclear waste. One example is Uranium-235, which is used widely by nations that have a nuclear weapons program. U-235 has a half-life of 703,800,000 years. This means that U-235 will take over 700 million years for it to decompose by half. It is estimated that these elements will still be hazardous for ten times their half-lives. At this rate, U-235 will take around 7 billion years for it to become non-threatening to humans. It should be noted that seasons, temperature, or any known solvents will not affect the rate of decay. During the Cold War, very little attention was paid to the high volume of radioactive waste generated and even less to its effects on the environment. U-235 is an extreme example, we still have to contend with low level radioactive waste produced daily by Industry and Medical facilities. Some of the effects on the environment are; groundwater contamination, soil contamination, buried soil and water containing waste, and underground disposal facilities storing large volumes of hazardous, radioactive waste. One such facility was the Yucca Mountain Nuclear Waste Repository, which was designated in 1987 by the NWPA Amendments, and located on federal land adjacent to the Nevada Test Site (NTS) in Nye County, Nevada some 80 miles Northwest of Las Vegas, Nevada. Congress approved the site in 2002,
The issue of radioactive waste is still an unsolved one. The waste from atomic vitality is to a great degree risky and it must be deliberately cared for a few thousand years (10'000 years as indicated by United States Environmental Protection Agency measures).
Nuclear energy is the energy released by a nuclear reaction, it uses fuel made from mined and processed uranium to generate heat and electricity. It is the world’s largest emission free energy source. Nuclear energy also has the lowest impact on the environment than other energy sources. But it can still be very harmful because of the radiation is causes and the radioactive waste it produces. Radioactive wastes are the ruins of nuclear materials that are used in providing nuclear energy. These wastes contain high levels of radiation that can be very hazardous to humans and the environment. Some people accept and support the idea of using nuclear energy and others don’t. In the following paragraphs, some major nuclear accidents and the public acceptance of nuclear energy will be discussed.
Such kind of waste emits radiations from tens to hundreds of years. These reactive radicals make the sand or the water contaminated. It is known as mixed waste. The mixture cause hazardous chemical reactions and leads to dangerous complications.
The problem with nuclear waste is getting worse everyday while we try and find a solution to dispose of the waste properly, however there are some people who think that the nuclear waste project for waste disposal is not that serious and it does not have an affect on the environment, but they are wrong because our lack of care for proper disposal of nuclear waste is having a tole on the environment where the waste is buried and the life forms around these waste sites.
