Three-dimensional mapping has extensively developed in the last decade; geological mapping being the area where these developments are more striking. 3D geological mapping has a myriad of applications in the domains of basin analysis, geophysics, geostatistics, geothermal and energy resources, etc. A parallel domain of development has been three-dimensional groundwater modelling: regional groun...

the disposal of nuclear wastes is one of the most controversial issues faced by authorities in japan. in this regard, a survey was conducted among 172 university students to analyze the attitude towards the sitting of a nuclear waste repository in the country. the study focused on a number of variables that influenced the perception of risks before the 2011 tohoku earthquake and tsunami. resul...

background: radiation shielding properties is an important for a material wish can be used the photon attenuation coefficients of clay produced using different rate of boron have been measured for the purpose of radioactive waste disposal. materials and methods: the measurement has been performed using gamma spectrometer contains nai (tl) detector at the photon energies of 662, 1173 and 1332 ke...

New European directives have proposed the direct application of compost and digestate produced from municipal solid wastes as organic matter sources in agricultural soils. Therefore information about phosphorus leaching from these residues when they are applied to the soil is increasingly important. Leaching experiments were conducted to determine the P mobility in compost and digestate mixture...

Here we summarize the findings of this report on the history and current status of radioactive waste management in ten countries. The case studies include four countries that reprocess nuclear spent fuel (France, Japan, Russia, and the United Kingdom), five countries that are planning on direct disposal of spent fuel (Canada, Finland, Germany, Sweden, and the United States) and one country (Sou...

In this study, Citrus sinensis (C. sinensis) solid waste was used to catalyze the conversion of free cyanide (F-CN) under alkaline conditions; conditions which represent most industrial wastewater containing F-CN. Acid hydrolysis of the solid waste increased the catalytic conversion of FCN by 3.86 compared to the unhydrolysed solid waste. The conversion of F-CN using unhydrolysed and hydrolysed...

"This study develops a methodology that allows migration decision-making to be studied in a laboratory experimental setting. Moreover, this methodology permits an examination of the importance of natural and man-made hazards in migration decisions--factors that have not been extensively studied as determinants of migration. The specific application is to the location of the U.S. nuclear waste ...

The Regional Ground Water Forum is a group of ground-water technical specialists, representing EPA's Regional Offices, organized to exchange up-to-date information related to groundwater remediation at hazardous waste sites. Proper site characterization has been identified by the EPA Regional Ground Water Forum as a major issue of concern for decision-makers at many hazardous waste sites. In or...

This paper describes the general system for regulation of disposal of solid, long-lived radioactive wastes. It outlines the relevant Government policy, the framework of legislation and arrangements for implementation, the associated guidance produced by regulatory bodies and the approach to assessment by regulators of a safety case for radioactive waste disposal. Also, for the purposes of discu...
