1. Radioactive waste

   Radioactive waste is a type of hazardous waste that contains radioactive material. Radioactive waste is a result of many activities, including nuclear medicine, nuclear research, nuclear power generation, nuclear decommissioning, rare-earth mining, and nuclear weapons reprocessing. The storage and disposal of radioactive waste is regulated by government agencies in order to protect human health and the environment. Radioactive waste is broadly classified into low-level waste (LLW), such as paper, rags, tools, clothing, which contain small amounts of mostly short-lived radioactivity, intermediate-level waste (ILW), which contains higher amounts of radioactivity and requires some shielding, and high-level waste (HLW), which is highly radioactive and hot due to decay heat, so requires cooling and shielding. In nuclear reprocessing plants about 96% of spent nuclear fuel is recycled back into uranium-based and mixed-oxide (MOX) fuels. The residual 4% is minor actinides and fission products the latter of which are a mixture of stable and quickly decaying (most likely already having decayed in the spent fuel pool) elements, medium lived fission products such as strontium-90 and caesium-137 and finally seven long-lived fission products with half lives in the hundreds of thousands to millions of years. The minor actinides meanwhile are heavy elements other than uranium and plutonium which are created by neutron capture. Their half lives range from years to millions of years and as alpha emitters they are particularly radiotoxic. While there are proposed - and to a much lesser extent current - uses of all those elements, commercial scale reprocessing using the PUREX-process disposes of them as waste together with the fission products. The waste is subsequently converted into a glass-like ceramic for storage in a deep geological repository. The time radioactive waste must be stored for depends on the type of waste and radioactive isotopes it contains. Short-term approaches to radioactive waste storage have been segregation and storage on the surface or near-surface. Burial in a deep geological repository is a favored solution for long-term storage of high-level waste, while re-use and transmutation are favored solutions for reducing the HLW inventory. Boundaries to recycling of spent nuclear fuel are regulatory and economic as well as the issue of radioactive contamination if chemical separation processes cannot achieve a very high purity. Furthermore, elements may be present in both useful and troublesome isotopes, which would require costly and energy intensive isotope separation for their use - a currently uneconomic prospect. A summary of the amounts of radioactive waste and management approaches for most developed countries are presented and reviewed periodically as part of a joint convention of the International Atomic Energy Agency (IAEA).

1. radioactive waste

   Radioactive waste is a type of hazardous waste that contains radioactive material. It is usually a product of a nuclear process, such as nuclear fission, or the use of radionuclides in science, medicine, and industry. Radioactive waste can pose significant health and environmental risks, requiring special methods for treatment, storage, and disposal to protect people and the environment.

1. Radioactive waste

   Radioactive wastes are wastes that contain radioactive material. Radioactive wastes are usually by-products of nuclear power generation and other applications of nuclear fission or nuclear technology, such as research and medicine. Radioactive waste is hazardous to most forms of life and the environment, and is regulated by government agencies in order to protect human health and the environment. Radioactivity diminishes over time, so waste is typically isolated and stored for a period of time until it no longer poses a hazard. The period of time waste must be stored depends on the type of waste. Low-level waste with low levels of radioactivity per mass or volume may need to be stored for only hours or days while high-level wastes the time frames in question range from 10,000 to millions of years. Current major approaches to managing radioactive waste 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 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 International Atomic Energy Agency Joint Convention on the Safety of Spent Fuel Management and on the Safety of Radioactive Waste Management.

Examples of radioactive waste in a Sentence

1. Jeff Navin:

   Some of the biggest national security questions facing the country run through Piketon and Kemmerer, a Post-Soviet dealAmerican reliance on foreign enriched uranium echoes its competitive disadvantages on microchips and the critical minerals used to make electric batteries — two essential components of the global energy transition.But in the case of uranium enrichment, United States once had an advantage and chose to give it up.In the 1950s, as the nuclear era began in earnest, Piketon became the site of one of two enormous enrichment facilities in the Ohio River Valley region, where a process called gaseous diffusion was used.Meanwhile, the Soviet Union developed centrifuges in a secret program, relying on a team of German physicists and engineers captured toward the end of World War II. Its centrifuges proved to be 20 times as energy efficient as gaseous diffusion. By the end of the Cold War, United States and Russia had roughly equal enrichment capacities, but huge differences in the cost of production.In 1993, Washington and Moscow signed an agreement, dubbed Megatons to Megawatts, in which United States purchased and imported much of Russia’s enormous glut of weapons-grade uranium, which United States then downgraded to use in power plants. This provided the U.S. with cheap fuel and Moscow with cash, and was seen as a de-escalatory gesture.But it also destroyed the profitability of America’s inefficient enrichment facilities, which were eventually shuttered. Then, instead of investing in upgraded centrifuges in United States, successive administrations kept buying from Russia.ImageA mural celebrates Piketon’s gaseous diffusion plant, long ago shuttered, and United States role in the local economy.Credit... Brian Kaiser for The New York TimesImageIn the lobby at Piketon plant, a miniature display of new centrifuges.Credit... Brian Kaiser for The New York TimesThe centrifuge plant in Piketon, operated by Centrus Energy, occupies a corner of the site of the old gaseous diffusion facility. Building United States to United States full potential would create thousands of jobs, according to Centrus Energy. And it could produce the kinds of enriched uranium needed in both current and new-age nuclear plants.Lacking Piketon’s output, plants like TerraPower’s would have to look to foreign producers, like France, that might be a more politically acceptable and reliable supplier than Russia, but would also be more expensive.TerraPower sees itself as integral to phasing out climate-warming fossil fuels in electricity. Its reactor would include a sodium-based battery that would allow the plant to ramp up electricity production on demand, offsetting fluctuations in wind or solar production elsewhere.It is part of the energy transition that coal-country senators like Mr. Manchin and John Barrasso, a Wyoming Republican, are keen to fix as they eye nuclear replacements for lost coal jobs and revenue. While Mr. Manchin in particular has complicated the Biden administration’s efforts to quicken the transition away from fossil fuels, he also pushed back against colleagues, mostly Democrats, who are skeptical of nuclear power’s role in that transition, partly because of the radioactive waste it creates.
