Glacier-bed geomorphic processes and hydrologic conditions relevant to nuclear waste disposal

Nuclear waste disposal.

-Experiments are described in which dose-response data have been obtained for EMT6 mouse tumour cells growing in vivo and exposed to various cytotoxic agents. A comparison has been made of the response of solid tumours in the flank and of rapidly growing lung nodules. The results are discussed with regard to their cell kinetic implications and compared with our results for the chemosensitivity ...

Developments in Nuclear Waste Disposal

Hydrologic issues associated with nuclear waste repositories

Significant progress in hydrology, especially in subsurface flow and solute transport, has been made over the last 35 years because of sustained interest in underground nuclear waste repositories. The present paper provides an overview of the key hydrologic issues involved, and to highlight advances in their understanding and treatment because of these efforts. The focus is not on the developme...

Chemical and Nuclear Waste Disposal: Problems and Solutions

The problems of waste disposal have always been with us. In biblical times, the residents of Jerusalem always burnt their wastes in the hideous Vale of Gehenna. This gave way to burial of waste or sometimes dumping it in shallow oceans. All too often the sewage pipes of the seaside towns did not even take the waste to the low tide mark; and the use of the deep oceans as a disposal site has been...

Mobile fission and activation products in nuclear waste disposal.

When disposing nuclear waste in clay formations it is expected that the most radiotoxic elements like Pu, Np or Am move only a few centimetres to meters before they decay. Only a few radionuclides are able to reach the biosphere and contribute to their long-term exposure risks, mainly anionic species like I129, Cl36, Se79 and in some cases C14 and Tc99, whatever the scenario considered. The rec...
