Removal of Chalk River unidentified deposit (CRUD) radioactive waste by enhanced electrokinetic process

Removal of nickel from paddy soil by electrokinetic reclamation process, a case study of Silakhor plain (Lorestan)

Background and Objective: Application of chemical fertilizers in agricultural industry is known as one of the methods of crop enhancement. However, chemical fertilizers application can lead to an increased risk of chemical pollutants entering the human food cycle.  The aim of current research was feasibility study and evaluation of nickel from paddy soils in Lorestan province. Materials and Me...

Monte Carlo simulation of contaminant release from a radioactive waste deposit

This paper addresses the problem of radionuclides transport through the artificial porous matrices constituting the engineered barriers of a permanent deposit for radioactive wastes under design by the Italian Agency for Energy and Environment, ENEA. The complexity of the phenomena involved, augmented by the heterogeneity and stochasticity of the media in which transport occurs, renders the cla...

Enhanced electrokinetic removal of phenanthrene from clay soil by periodic electric potential application.

Electrokinetically enhanced in-situ flushing using surfactants has the potential to remove polycyclic aromatic hydrocarbons (PAHs) from low permeability clay soils; however, previous research has shown that the applied electric potential produces complex physical, chemical, and electrochemical changes within clay soils that affect mass transfer and overall efficiency. This article presents the ...

Disposal of Radioactive Waste

Perhaps the most important single problem arising from the increasing use of atomic energy for peaceful purposes is how to dispose of the growing amounts of radioactive waste. Many of its complex aspects were discussed at the scientific conference on the disposal of radioactive waste held by IAEA in Monaco from 16 to 21 November 1959. The conference was organized jointly with UNESCO, with the c...
