Safety radioactive waste disposal

Radioactive waste management is a quite mature field of application of basic geoscientific disciplines. As we will discuss in forthcoming sections, the long-term performance and henceforth the safety of radioactive waste disposal systems, deeply relies on the basic principles that control the release, mobility, and transport of the chemical elements in the geosphere. In the context of radioactive waste disposal, the waste matrix constitutes the innermost of the barriers that may control the release and ulterior transport of radionuclides through the ground-water systems.

In any case, and albeit the different regulation in different countries, as a general principle only licensed personnel working in an authorized facility are authorized to handle and use radiopharmaceuticals. Facilities and procedures are subject to periodic inspection by official radiation safety officers that control production and handling of radioactive material, its transportation, proper use, as well as personnel dosimetry and radioactive waste disposal. 

The Radioactive Waste Management Committee (RWMC) of the OECD Nuclear Energy Agency recognised the need for an internationally acknowledged, high-quality thermochemical data base for the application in the safety assessment of radioactive waste disposal, and undertook the development of the NEA Thermochemical Data...

Improved understanding of the health effects of low levels of radiation, where currently standards are set by simple linear extrapolation of health effects observed at large doses, may potentially result in reassessment, either up or down, in the safety of nuclear power and the consequences of nuclear accidents. The demonstration of a threshold for radiation effects, postulated by some researchers, would result in a major decrease in the calculated consequences of severe accidents, and would also affect design requirements for radioactive waste disposal.

This branch of chemistry began with the discovery of natural radioactivity by Antoine Becquerel and grew as a result of subsequent investigations by Pierre and Marie Curie and many others. Nuclear chemistry is very much in the news today. In addition to applications in the manufacture of atomic bombs, hydrogen bombs, and neutron bombs, even the peaceful use of nuclear energy has become controversial, in part because of safety concerns about nuclear power plants and also because of problems with radioactive waste disposal. In this chapter, we wiU study nuclear reactions, the stability of the atomic nucleus, radioactivity, and the effects of radiation on biological systems. 

Absolute safety does not exist in any human activity, and much less so in industry. I believe, however, that nuclear power plants are every day safer and that radioactive waste disposal facilities will be safer still. Generally speaking it may be said that public concern for safety in this sector has forced those involved to enhance the measures takoi. It should also be pointed out, however, diat...

There exists today an extensive literature documenting the techniques, the applications and the results of safety assessments. This basis makes it feasible to provide guidance and advice on safe r assessments for radioactive waste disposal facilities near the surface or at depth. A major part of the IAEA RADWASS documentation is being devoted to this topic. 

Note this protocol should be performed only by persons trained in the use of radioisotopes. Perform the entire operation in a designated fume cabinet use suitable safety precautions during the procedure, and approved methods of radioactive waste disposal. 

In the preparation of this publication account was taken of the reconunenda-tions of other international bodies, in particular the International Conunission on Radiological Protection (ICRP) and the OECD s Nuclear Energy Agency (NEA), on criteria for radioactive waste disposal. The safety principles contained in this book are generally consistent with the recent recommendations of these two bodies. 

It is recognized that radioactive waste disposal is only one, albeit the final, step in the sequence of operations in the nuclear fuel cycle that give rise to radiation exposure. All these operations should comply with the Basic Safety Standards for Radiation Protection adopted by the IAEA (Safety Series No. 9, 1982 Edition) and, accordingly, each one must be optimized this also iplies to the nuclear fuel cycle system as a whole in order that radiation exposures are kept as low as reasonably achievable. 

The long term safety of high level radioactive waste disposal shall be based on the multibarrier concept, and shall be assessed on the basis of the performance of the disposal system as a whole. 

It is recognized that the long term safi of a high level radioactive waste disposal system cannot be demonstrated directly. However, it can be indirectly demonstrated by evaluation using predictive analyses based on technical and scientific data. Demonstration of compliance with numerical safety criteria therefore...
