An introduction to the issue of radioactive wastes

Deep geological disposal allows present generations to progress without leaving burdens for those of the future, but a main weakness is that although the concept is technically sound, it is rarely socially or politically accepted.

High-level wastes include spent nuclear fuel from commercial nuclear reactors and reprocessing wastes both liquids and solids from the nuclear weapons program. Visit the NEA website at http: The topic of radioactive waste seems pretty broad.

An overview of radioactive waste disposal procedures of a nuclear medicine department

Some DU is used in applications where its extremely high density makes it valuable, such as for the keels of yachts and military projectiles. Intergenerational Equity Intergenerational equity concerns are raised by the fact that long-lived nuclear waste poses a risk over many generations.

Radioactive Waste

But in addition, it is also waste that is not transuranic waste, spent nuclear fuel, or byproduct material as defined in the Atomic Energy Act AEA. Many natural mineral compounds, such as clays e. This section will summarize recent researches devoted to prepare, characterize and test new sorbent materials.

How are they classified? Kates and Braine show that gains and losses associated with a hazardous waste site linked to the nuclear waste reprocessing facility at West Valley, New York, affected more than a dozen locations stretching across the United States.

Without the proper disposal what is not dangerous has the possibilities of becoming that way.

Radioactive elements lose their radioactivity only through the passage of time and the process of radioactive decay.

The majority of waste originates from the nuclear fuel cycle and nuclear weapons reprocessing. Insoluble transition metal hexacyanoferrates have been known for decades as effective agents for the removal of radionuclides from waste solution [ 26 ].

In the meantime, many programs will have to shape new initiatives under conditions of considerable social distrust Kasperson et al. Well, Class A wastes are buried in trenches designed to contain the wastes for years, Class B wastes are buried in separate trenches designed for year containment periods.

The produced material is granular with sufficient strength for column use from sorbents that do not form or only form weak, granules. Radioactive waste is not unique to the nuclear fuel cycle. As with many issues we deal with in everyday life, we learn as we go. Tell me more about this particular disposal method.

The Nuclear Waste Policy Act was passed in A decision-making process should be set up step by step, and all the affected groups should be allowed to participate.The book thoroughly covers all issues surrounding nuclear waste: from where to locate nuclear waste in the environment, through nuclear waste generation and sources, treatment schemes and technologies, immobilisation technologies and waste forms, disposal and long term behaviour.

Drawing on the authors’ extensive experience in the processing and disposal of waste, An Introduction to Nuclear Waste Immobilisation, Second Edition examines the gamut of nuclear waste issues from the natural level of radionuclides in the environment to geological disposal of waste-forms and their long-term behavior.

It covers all-important aspects of processing and immobilization, including nuclear decay, Author: Michael I Ojovan. The NRC requires that wastes be solidified in some form after five years.

The disposal of nuclear wastes is a very real problem with which society will have to deal. Radioactive waste from nuclear medicine procedures can be dealt with either by simply storing the wastes safely till radioactive decay reduces the activity to a safe level or possibly by disposal of low-activity waste into the sewage system.

1. Introduction. The generation of radioactive wastes varies from country to country depending on the scale of applications and range of activity associated with nuclear and radioactive material utilization in.

Societal Issues in Radioactive Waste Management Placing high-level radioactive waste (HLW) in a deep geological repository has been the solution accepted by .
