Radioactive waste From Wikipedia, the free encyclopedia Jump to: navigation search Radioactive waste is a waste product containing radioactive material. It is usually the product of a nuclear process such as nuclear fission , though industries not directly connected to the nuclear power industry may also produce radioactive waste. Radioactivity diminishes over time, so in principle the waste needs to be isolated for a period of time until it no longer poses a hazard. This can mean hours to years for some common medical or industrial radioactive wastes, or thousands of years for high-level wastes from nuclear power plants and nuclear weapons reprocessing. The majority of radioactive waste is " low-level waste ", meaning it has low levels of radioactivity per mass or volume The main approaches to managing radioactive waste to date have been segregation and storage for short-lived wastes, near-surface disposal for low and some intermediate level wastes, and deep burial or transmutation for the long-lived, high-level wastes. A summary of the amounts of radioactive wastes and management approaches for most developed countries are presented and reviewed periodically as part of the IAEA Joint Convention on Safety of Spent Fuel Management and the Safety of Radioactive Waste Management.

It is often the product of a nuclear process, such as nuclear fission . Waste can also be generated from the processing of fuel for nuclear reactors or nuclear weapons The radioactivity of all nuclear waste diminishes with time. All radioisotopes contained in the waste have a half-life The faster a radioisotope is decaying, the more radioactive it will be. Another factor in deciding how dangerous a pure radioactive substance will be is the energy of the radiation. Some decays yield more energy than others. This is further complicated by the fact that few radioisotopes decay immediately to a stable state, but rather to a radioactive decay product leading to decay chains The main objective in managing and disposing of radioactive (or other) waste is to protect people and the environment. This means isolating or diluting the waste so that the rate or concentration of any radionuclides returned to the biosphere is harmless. To achieve this for the more dangerous wastes, the preferred technology to date has been deep and secure burial.

You are here: Home Page Radioactive substances Radioactive waste Radioactive waste SEPA is responsible for regulating the disposal of radioactive waste from all sites and it's storage on non nuclear sites. This page tells you about the different levels of radioactive waste and how it is currently stored. Different levels of waste There are three types of radioactive waste that must be stored or disposed of in Scotland and the UK. These are low level, intermediate and high level waste. Low level waste accounts for about 90% of solid radioactive waste produced (by volume) in the UK. It is generally made up of everyday materials, such as plastics, glass, metals and paper, which have come into contact with radioactive liquids or powders. While most of it comes from the nuclear industry, it is also produced by non-nuclear industries, such as hospitals and universities. Of the remainder, nearly 10% of waste is intermediate and 0.1% high level. Although a relatively small volume, high level waste contains over 95% of the total radioactivity of all nuclear wastes. It is therefore vital that all waste produced as a result of nuclear activity is safely stored and disposed of. In September 2001, the UK Government launched a public consultation called "Managing Radioactive Waste Safely". One key outcomes of the consultation was a decision by UK Government to set up the independent Committee on Radioactive Waste Management (CoRWM) in November 2003:

High-level Radioactive Waste Management - Wikipedia, The Free Encyclopedia Highlevel radioactive waste management concerns management and disposal of highly radioactive materials created during production of nuclear power and nuclear warheads. http://en.wikipedia.org/wiki/Radioactive_waste_disposal

High-level radioactive waste management From Wikipedia, the free encyclopedia   (Redirected from Radioactive waste disposal Jump to: navigation search High-level radioactive waste management concerns management and disposal of highly radioactive materials created during production of nuclear power and nuclear warheads . The technical issues in accomplishing this are daunting, due to the extremely long periods radioactive wastes remain deadly to living organisms. Of particular concern are two long-lived fission products Technetium-99 (half-life 220,000 years) and Iodine-129 (half-life 15.7 million years), which dominate spent nuclear fuel radioactivity after a few thousand years. The most troublesome transuranic elements in spent fuel are Neptunium-237 (half-life two million years) and Plutonium-239 (half-life 24,000 years). Consequently, high-level radioactive waste requires sophisticated treatment and management to successfully isolate it from the biosphere . This usually necessitates treatment, followed by a long-term management strategy involving permanent storage, disposal or transformation of the waste into a non-toxic form. Governments around the world are considering a range of waste management and disposal options, usually involving deep-geologic placement, although there has been limited progress toward implementing long-term waste management solutions.

A preferred rehabilitation option, one of a range of options developed by technical advisers (the Technical Assessment Group), was agreed to in 1991 by the Australian and South Australian governments and the traditional Aboriginal owners, Maralinga Tjarutja,. Work commenced on the Project in 1996 and was completed in 2000. The Project was conducted in accordance with International Atomic Energy Agency and International Commission on Radiological Protection guidelines on the rehabilitation of contaminated sites, and with relevant Australian codes of practice. The Australian Radiation Protection and Nuclear Safety Agency (ARPANSA) monitored the Project, and issued clearance certificates for the remediated areas.

Home Electronic Reading Room Basic References Students' Corner ... Games Nuclear power plants generate two types of waste: high-level and low-level. High-level waste includes the fuel used in the nuclear reactor called spent fuel . It is highly radioactive and very dangerous. It must be cooled for several years in deep pools inside the plant or in special storage facilities outside of the plant site. It can remain in the pool or later be transferred to special casks, which are like big, concrete barrels. Some of the fission products in the spent fuel will take many years to lose their radioactivity. A special disposal site is needed for this type of spent fuel. The U.S. Department of Energy wants to build such a site at Yucca Mountain, Nevada. The spent fuel, in heavy casks, would remain buried there for thousands of years. The NRC must approve and license this site to make sure it is safe. Low-level waste can come from nuclear reactors or from hospitals or universities. Low-level waste is not as dangerous as high-level waste. It can be shipped to low-level waste disposal facilities. There, it is packaged, buried in trenches and covered with soil. States are responsible for selecting new disposal sites or using those that already exist. STILL HAVE QUESTIONS?
