Utilization of Radioactive Contaminated EAF Dust as Material for Making Paving Block

Downblending Contaminated Radioactive Wastes

Dilution is the mixing of radioactive waste with non-radioactive material, whereas downblending is the mixing of high-level radioactive waste with low-level radioactive waste. These processes have been applied predominantly at nuclear sites as part of the decontamination procedures for the disposal of blended wastes in licensed facilities. Proper health and safety assessments should be carried ...

International policies and strategies for the remediation of land contaminated by radioactive material residues.

The paper addresses the international policies and strategies for the remediation of land contaminated by radioactive material residue, its main aim being to describe the misunderstandings, evolution and status of the international paradigms in this area. Thus, the denotation and connotation of the 'remediation' and 'contamination' concepts are explored, including the ambiguity they produce in ...

Utilization of Eaf Metallurgical Slag in “green” Belite Cement

În acest studiu, zgură de cuptor cu arc electric (EAFS) colectată de la Sovel S.A., Grecia şi calcar şi argilă, de la compania de ciment Titan S.A., Grecia, au fost utilizate pentru producerea şi caracterizarea cimenturilor tip belitice. Trei tipuri de clincher au fost preparate: belitic fara adaos de zgură folosit ca referinţă (BC), unul cu 5wt% EAFS (BC5) şi un altul cu 10wt% EAFS (BC10). Ana...

Making Decision Support System for Utilization of Biogas in Iran

The use of renewable energy sources is often suggested to be a good solution for climate change and the dependency to fossil fuel. Biogas utilization is a one of these promising options that can mitigate these problems since biogas is produced by the fermentation of waste, so is rich in methane and has the same characteristics as natural gas. Biogas has increasingly been noticed in different co...
