means, patience, management, and technical skills they are likely to have." First, neither plutonium nor uranium, the materials from which bombs are made, is "highly radioactive." They are alpha emitters and as long as they are not breathed in or absorbed through a cut they can be safely handled for hours without any significant radiological hazard. Is it really so difficult to make a crude bom...

The goal of this research is to develop electrochemically “switchable” separations that can be performed on-line with mass spectrometry for rapid elemental and isotopic analysis of actinides. The separation of uranium and plutonium, as well as other actinide elements, from complex solutions such as seawater, radioactive wastes and nuclear reprocessing solutions will benefit from a separation pr...

Low-level liquid concentrate wastes including boric acid have been immobilized with paraffin wax using concentrate waste drying system in Korean nuclear power plants since 1995. Small amount of low density polyethylene (LDPE) was added to increase the leaching resistance of the existing paraffin waste form and the influence of LDPE on the leaching behavior of waste form was investigated. It was...

Current United States military chemical protective ensembles do not provide for feeding, removing body wastes, or ensuring the hygiene of troops operating in a contaminated environment. As part of a nuclear-biological-chemical life support demonstration program, systems were developed to provide these capabilities. The nutrient system consisted of foods packaged in tube dispensers and a deliver...

The proper treatment and characterization of past hazardous waste sites is becoming more and more important as world population extends into areas previously deemed undesirable. Historical photographs, past records, current aerial satellite imagery can play an important role in characterizing these sites. These data provide clear insight into defining problem areas which can be surface sampled ...

electronic wastes (e-wastes) is the most rapidly growing segment of the municipal waste stream. e- wastes comprise 2-5 percent of municipal solid wastes, including many different electronic products. iran is the biggest consumer of electronic products in middle east. approximately, 1.2 million computers are assembled in iran every year. there are more than 40 million active cell phones in iran....

The wastes produced during the manufacture and use of paints have long been an environmental concern. Paint manufacturers have sought ways to reduce these wastes with significant success. Industrial paint users have also identified and implemented techniques and technologies to reduce their paint wastes. Frequently, these activities also result in reduced production and disposal costs. Despite ...

In this paper two common collocation approaches based on radial basis functions have been considered; one be computed through the integration process (IRBF) and one be computed through the differentiation process (DRBF). We investigated the two approaches on natural convection heat transfer equations embedded in porous medium which are of great importance in the design of canisters for nuclear ...

Of the 12 billion tons of waste generated annually in the United States; less than 10% is defined as hazardous under the provisions of RCRA. This paper summarizes the data available on some of the wastes that are defined as non-hazardous. These wastes include industrial non-hazardous waste, and several types of wastes that are currently exempted from hazardous waste regulations, such as oil and...
