Management of high level radioactive wastes

Annals of Nuclear Science and Engineering, 1974
Abstract Many groups of workers throughout the world are considering possible methods of storage or disposal of high level fission product wastes. It is the view of the United Kingdom that these wastes must be fixed in solids and must be retrievable, that is they should be stored and not disposed of.

High‐Level Radioactive Waste Management

Water Environment Research, 2010
This review highlights the status of research and advancements made in high‐level radioactive waste management programs around the world in 2010 from published technical literature, books, and reports. The review covers waste form and repository, engineered barrier and sorption, repository, biological interactions, transport and mathematical modeling ...

Leaching of Vitrified High-Level Radioactive Waste

MRS Proceedings, 1981
The work reported here is part of a study of the leaching of individual elements from waste glasses. The first part of the paper reports on leaching of the major constituents at 30°C, and leaching of the alkalis at 2°C from glass UK189; the second part describes leaching of Sr, Cs, Tc and various actinides from glasses UK189 and UK209. Compositions are

High-Level and Long-Lived Radioactive Waste Disposal

Science, 1977
No uniform international approach for handling the problem of high-level radioactive waste disposal exists. All the while, the volume of these wastes continues to grow. The only viable solution to the disposal problem is a geologic one. Burial of these wastes in solid form for long periods of time in mined cavities in salt or Precambrian crystalline ...

High‐level radioactive waste management in the USA

Journal of Risk Research, 2009
High‐level radioactive waste (HLW) disposal policy in the USA since 1987 has focused on a site in volcanic tuffs 305 meters beneath Yucca Mountain, Nevada, with current plans calling for the repository to be opened in 2017 subject to approval by the Obama Administration.

Hazards of High-Level Radioactive Waste—The Great Myth

1983
The fourth major reason for public misunderstanding of nuclear power is a grossly unjustified fear of the hazards from radioactive waste. Even people whom I know to be intelligent and knowledgeable about energy issues have told me that their principal reservation about use of nuclear power is the disposal of radioactive waste. Often called an “unsolved

Concept of a canister for high-level radioactive waste

Nuclear and Chemical Waste Management, 1982
Abstract The specific problem of developing a canister for the multibarrier waste isolation concept was considered. A conceptual design was developed for a canister that is relatively easy to fabricate, inspect, and handle. The design has the option of storing the canister or adding an overpack before storage.

Disposal of high-level radioactive wastes by burial in the sea floor

Environmental Science & Technology, 1982
The U.S. Subseabed Disposal program is discussed briefly. A short history of research work done on this disposal is given, along with how the disposal criteria were formulated. The authors conclude that the results to date indicate that the method is promising and that subseabed disposal may begin about the year 2010. (JMT)

Seabed disposal of high-level radioactive waste

1987
As with on-land disposal seabed disposal of high-level radioactive waste is a multi-barrier concept. The concept envisages that waste would be vitrified and then packed into containers and overpacks before being placed on the seabed, or buried at varying depths within its soft sediment covering and the underlying lithified sediments and oceanic basalts.
