Uranium Retention in Silica-Rich Natural Glasses: Nuclear Waste Disposal Aspect

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

In Search of a Nuclear Waste Disposal Site

The choice of a site for high and intermediate level nuclear waste product material disposal in Jordan requires careful consideration of hydrology, hydrogeology, geological materials, seismicity, climate and other geological factors. The purpose of this paper is to explore how these factors in Jordan may affect the ultimate decision on where to site such a facility. Taking these factors into co...

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...

Evaluation of the heat transfer rate increases in retention pools nuclear waste

In this paper, we have tried to find a solution for quick transfer of nuclear wastes from pools of cool water to dry stores to reduce the environmental concerns and financial cost of burying atomic waste. Therefore, the rate of heat transfer from atomic waste materials to the outer surface of the container should be increased. This can be achieved by covering the bottom of the pool space with c...
