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 long-forgotten settlement in a muddy field ...

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 ...

Nuclear Plant in southeastern United States case study
Turning Liquid Waste into Solid Money Savings using QUIK-SOLID© Project Background: A nuclear plant located in southeastern United States had to dispose of approximately 7,000 gallons (26,488 L) of liquid sludge that resulted from aggressive preventive maintenance activities. The plant stored the watery sludge in B-25 boxes (90 ft each). The slightly contaminated waste consisted of free ...

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 ...

Counting solutions LSC technical tips from PerkinElmer
The advance of the nuclear industry in all its forms coupled with growing concerns for possible environmental contamination has led to an increased interest in the quantification of radioisotopes in the environment. Radionuclides currently present in the environment originate from a variety of sources such as fallout from nuclear weapons testing, and in discharges from both nuclear and ...

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 ...

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 ...

CJSC ECOMET-S facility for reprocessing and utilisation of radioactive metal waste: operating experience
The principal objective of the paper is to present operating experience in management of radioactive metal waste, originating at nuclear power facilities of the Russian Federation. Issues of radioactive metal waste recycling by melting, with the purpose of unrestricted re-use in industry, or restricted re-use within the nuclear industry, have been considered. The necessity for using a method of ...

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 ...

Evolution of Disposal Cell Cover Design Used for Uranium Mill Tailings Long-Term Containment
ABSTRACT Technology used to design protective covers overlying hazardous and low-level radioactive waste cells evolved significantly during the course of the Uranium Mill Tailings Remedial Action (UMTRA) Project. Our country's operational experience in long-term containment of hazardous and radioactive wastes has been gained primarily through efforts expended by the UMTRA Project ...

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 ...

Ionising Radiation
Introduction The energy level of some types of radiation is high enough so that when they interact with matter they cause the formation of electrically charged particles or ion-pairs and break molecular bonds. These so-called ionising radiations are by their nature potentially harmful to life; at high doses they can be lethal and at lower doses can cause genetic damage. Ionising radiation occurs ...

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 ...
