  • Low-Level Waste Projection Program Guide

    The U. S. Department of Energy (DOE or the Department) is taking a structured approach for the determination of its low-level waste (LLW) disposal needs through the development of this Low-Level Waste Projection Program Guide (referred to as the Guide). The Department has developed this Guide as part of a process to improve the management of DOE LLW. This Guide has been prepared by the Office of ...

  • 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 ...

  • 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 ...

  • Direct contact membrane distillation for nuclear desalination, Part II: experiments with radioactive solutions

    This paper proposes the application of Direct Contact Membrane Distillation (DCMD) coupled with a nuclear reactor for water desalination and for low- and medium-level radioactive liquid waste concentration. Both laboratory and pilot plant experiments were carried out using the membranes reviewed in Part I of this paper. The effects of process parameters on the productivity and quality of DCMD ...

  • 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 ...

  • Waste Management Overview

    Introduction Our Nation has entered an era in which, as a result of changing world conditions, nuclear weapons production is receiving less attention while the public is expressing increasing concern about protecting human health and preserving the quality of our environment. In response to this national concern, the Department of Energy (DOE) has made waste cleanup and environmental restoration ...

  • Management of spent nuclear fuel and its waste

    The spent nuclear fuel from the operation of nuclear power plants needs to be managed in a safe, responsible and effective way. Several possibilities exist to deal with the spent fuel. Within the so-called “open fuel cycle”, it is disposed of without further use. When “closing the fuel cycle”, the energetic component in the spent fuel, plutonium and uranium, is extracted ...

  • Review on hospital wastes and its possible treatments

    Medical waste management is of a great importance due to its potential impact to environment and consequently to human health. In the recent years, many efforts have been made by environmental regulatory agencies and waste generators to better managing the wastes from healthcare facilities. In the past, medical waste was often mixed with municipal solid waste and disposed in residential waste ...

  • Application of an intelligent decision system to nuclear waste repository option analysis

    This paper presents how the evidential reasoning approach for multi-criteria decision analysis, with the support of its software implementation, Intelligent Decision System (IDS), can be used to analyse whether low level radioactive waste should be stored at the surface or buried deep underground in the territory of the community of Mol in Belgium. Following an outline of the problem and the ...

  • Nuclear Waste: Greatest environmental challenge facing society

    Dr Tim Johnson discusses how we can tackle the nuclear waste epidemic. A world full of waste They say you can tell a lot about a society by what it throws away. Like me, I’m sure you can recall the excitement of archaeologists on numerous TV documentaries, sifting through the remains of a rubbish dump or ‘midden’ on the edge of some ...

  • Selection and design criteria of supported liquid membrane for the treatment of rad-waste

    Supported Liquid Membrane (SLM) is an emerging trace metal pre-concentration technique. It has the ability to decontaminate radionuclides even from lean secondary effluent. SLM can be considered as a part of process intensification, which implies a closed loop operation. It has reduced space requirement as well as minimised secondary effluent generation and the number of unit steps. Proper ...

  • econ VacuDry® technology proves successful for the treatment of NORM wastes

    Large amounts of drilling sludge containing low levels of natural radioactivity is a resultant by-product of the oil and gas production process. These so-called NORM-sludges (Naturally Occurring Radioactive Material) are often contaminated with both mercury and hydrocarbons. The econ industries VacuDry® technology is recognized in Germany as the first choice for the extraction of the mercury ...

  • 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 ...

Canada's largest city has arguably received the most attention with regard to ...

  • Socio–environmental nuclear conflicts: the case of El Cabril

    Since the commissioning of the 'El Cabril' Central Storage Facility for Low– and Intermediate–level Radioactive Waste (hereafter 'El Cabril'), most people living in nearby towns and villages have regarded this nuclear facility with a marked degree of rejection and distrust. This study examines the process of analysis, management and intervention specifically designed and implemented with a view ...

  • Properties and Behavior of Radionuclides

    For the purposes of this document, radionuclides should be considered to have properties similar to those of other heavy metals.This does not imply that all radionuclides are heavy metals, but that the majority of sites requiring remediation of radioactively contaminated materials are contaminated with radionuclides that have similar properties. Like metals, the contaminants of concern are ...

  • Life after barnwell

    Medical facilities that retain dumping privileges at Barnwell, South Carolina’s host site for low-level radioactive waste (LLRW) are breathing sighs of relief, while dozens of former clients from outcast states are still holding their breath.
