Sub-seabed disposal of radioactive waste

This article considers two detailed reviews of the legal aspects of Sub-Seabed Disposal of Radioactive Waste, by Richard Macrory and Ray Purdy (January 2005) and the opinion of Christopher Katkowski Q.C. and Stephen Tromans, March 2005. In substance, both reviews conclude that for a sub-seabed repository accessed from land by tunnel, the relevant International Conventions, in particular the UN ...

Waste Disposal

Introduction The final step in the waste management process is waste disposal, the permanent isolation of waste. Some wastes can be managed and disposed safely with existing facilities and proven methods. Other Department of Energy (DOE) wastes require more complex disposal facilities. DOE has conducted extensive research into alternative waste disposal methods and has concluded that deep ...

Comparing policy, regulations and institutions for geological disposal of radioactive waste and carbon dioxide

This paper compares the policy, regulatory and institutional (PRI) settings of Radioactive Waste (RW) and Carbon Dioxide (CO2) disposal for selected countries. This comparison is premised on the following arguments: (a) the policy/political acceptance of nuclear power and coal power with Carbon Capture and Storage (CCS) technology to redress the climate change challenge will ...

Knowledge management for radioactive waste disposal: moving from theory to practice

The exponential growth in the knowledge base for radioactive waste management is a cause for concern in many national programmes. In Japan, this problem is exacerbated by a volunteering approach to siting of a deep geological repository, which requires particular flexibility in the tailoring of site characterisation plans, repository concepts and associated Performance Assessments (PAs). ...

Comparison of monitoring programmes of ultimate disposal facilities for radioactive waste and carbon dioxide

Reliable and cost–effective monitoring is an important part of making geological repositories safe, effective, and acceptable for radioactive waste disposal and carbon dioxide (CO2) storage. The major objectives of monitoring should include the evolution of disposal systems compared to the baseline data of the undisturbed site, as well as the validation of the assumptions and ...

Comparative assessment of ultimate disposal facilities for carbon dioxide and radioactive waste: overview and synthesis

The world community is seeking to move towards cleaner sources of energy for electricity generation to protect the environment. In addition to renewables, nuclear power and fossil fuel plants with carbon dioxide (CO2) capture and storage (CCS) are potential clean energy sources, if their wastes, i.e., radioactive material and CO2, are ...

Public perception of ultimate disposal facilities for radioactive waste and carbon dioxide: results from a cross–national comparison

The public perception of ultimate disposal facilities for Radioactive Waste (RW) and carbon dioxide (CO2) is crucial for the selection, construction and operation of such sites. This paper presents a cross–national comparison of the public perceptions of ultimate disposal facilities for RW and CO2 in the Czech Republic, Germany and ...

Comparison of cost estimates of final disposal facilities for carbon dioxide and high–level radioactive waste

This paper presents new research and new cost calculations for carbon dioxide (CO2) disposal in Cuba and Lithuania, as well as lessons from the comparative assessment of CO2 and high–level Radioactive Waste (RW) disposal costs in several countries. Nuclear power and CO2 Capture and Disposal (CCD) ...

Research trends in radioactive waste management: a global perspective

The present study is aimed at analysing the growth of literature on radioactive waste management. International Nuclear Information System (INIS) database is used as a data source to analyse the focused areas of this field for the period 1970–2011. Journal Citation Report–2010 is used for eliciting information related to journal impact factors. The database contained a total of 101,419 ...

Removal of Radioactive Effluent Waste from Uranium Enrichments Plants

In an effort to reduce greenhouse emissions many nations and multi-national corporations are once again focusing on the development of safe radioactive sources for energy generation. After a hiatus of some 20 years commercial nuclear power plants are being developed globally to satisfy increasing global energy demands. Whether for generation of electrical power or in the production of fission ...

New regulations for release in Germany: a chance for minimisation of radioactive waste and reduction of costs

The EURATOM Basic Safety Standards provided the occasion to establish comprehensive clearance regulations in German law. The new German Radiation Protection Ordinance contains detailed regulations regarding clearance of radioactive substances with negligible radioactivity from practices subject to authorisation. For about 300 radionuclides, there are mass- and surface-specific clearance levels ...

Lysimetric studies for modelling radioactive contaminant transport in soils

To assess the movement of contaminants in the soil mass surrounded by near/subsurface waste repository, researchers have developed several mathematical and numerical modelling techniques. However, most of these techniques consider remolded state of soil mass, which fail to reproduce exact in situ conditions and also have used inactive salts as model contaminants. Hence, in order to model ...

How to treat radioactive NORM sludge with VacuDry

NORM doesn’t sound like a big thing. But Naturally Occurring Radioactive Material might let the alarm bells ring. Everyone has heard of “radioactive material” and that sounds dangerous. However, most of this material is trapped deep in the ground beneath our feet. From there it reaches the surface, for example via the water cycle. Another possible pathway for NORM to reach the ...

High technology comes to Hazardous waste disposal – Case Study

Skyrocketing hazardous waste disposal costs for the USC/ Division, of C.R. Bard, Inc., Billerica, Massachusetts led them to a high technology solution. USC/, a medical products manufacturer that develops and produces angioplasty catheters, had seen its solid hazardous waste disposal costs rise to almost $500 per 55- ga/lon drum, excluding costs associated with inplant storage, handling, and ...

Ecological solution of the problem of handling liquid radioactive wastes – LRW (by the example of FSUE SSC RF RIAR)

A sharp reduction of nuclear waste amounts is possible if their elements are considered as source material of atomic complexes – SMAC. The prospect of their possible salvaging will require technological changes and ensuring safety of storage of the material till the need arises. Long experience in deep liquid radioactive waste disposal and accounting, calculations, and motivations demonstrate ...

Identifying potential repositories for radioactive waste: multiple criteria decision analysis and critical infrastructure systems

An approach for the analysis and management of multiple criteria critical infrastructure problems is put forth. Nuclear waste management involves complex tradeoffs under uncertainty. Among all waste either generated by nature or human activities, radioactive nuclear waste is the most toxic to human health and difficult to manage: it is known that some nuclear waste material will be radioactive ...

On the removal of silver and antimony radionuclides from radioactive liquid waste by some classical means

After partial upgrading of a research reactor at the Pakistan Institute of Nuclear Science and Technology, Islamabad, some waste effluents having 110mAg and 124Sb with higher activity levels than the disposal limits piled up because the waste storage capacity was not yet enhanced. Experimental work was conducted to arrive at some optimum procedure for the treatment of the waste to ensure smooth ...

New LWT system improves safety for workers dredging radioactive materials

Problem: Cleanup crews wanted to dredge radioactive sludge from hazardous waste pits without releasing contaminants to the environment. Solution: A remote-control system encloses the radioactive material during dredging and keeps workers at a safe distance. The Weldon Springs, Mo. Superfund site and remedial action project has four pits containing low-level radioactive raffinate debris and ...

Excavation, Retrieval, and Off-Site Disposal

Introduction: Contaminated material is removed and transported to permitted off-site treatment and/or disposal facilities. Some pretreatment of the contaminated media usually is required in order to meet land disposal restrictions. Confined disposal facilities (CDFs) are engineered structure enclosed by dikes and designed to retain dredged materials. A CDF may have a large cell for ...
