Systematic Analysis Method for Radioactive Wastes Generated from Nuclear Research Facilities

Methods for the Minimization of Radioactive Waste from Decontamination and Decommissioning of Nuclear Facilities METHODS FOR THE MINIMIZATION OF RADIOACTIVE WASTE FROM DECONTAMINATION AND DECOMMISSIONING OF NUCLEAR FACILITIES

Disposal of Radioactive Wastes

Almost all major nuclear operations produce residues containing radioactive materials; in reactor operations, for example, the fission products, new elements (such as plutonium) produced by neutron irradiation and the unfissioned nuclear fuel are all radioactive. Some of this material can be put to further use: useful radioisotopes, for instance, can be extracted from the fission products and p...

Downblending Contaminated Radioactive Wastes

Dilution is the mixing of radioactive waste with non-radioactive material, whereas downblending is the mixing of high-level radioactive waste with low-level radioactive waste. These processes have been applied predominantly at nuclear sites as part of the decontamination procedures for the disposal of blended wastes in licensed facilities. Proper health and safety assessments should be carried ...

Management of Wastes from Wood Preserving Facilities

INTRODUCTION Wood preserving is a significant, diverse and well established industry with five hundred forty-seven known operating plants in the United States. (1) The principal product of these plants is chemically treated wood for use as railroad ties, utility poles, and construction materials. In 1984, the industry treated about 500 million cubic feet of wood products. (2) Wood is chemically...

Potential for energy recovery from municipal plastic wastes generated in Nigeria

Management of municipal solid wastes (MSW) in most developed societies now involves the use of thermo-chemical conversion methods. This leads to energy and material recovery while also protecting the environment. However, till date most of the wastes generated in Nigeria (including plastic wastes) are either land-filled or openly burnt. These methods are not sustainable and environmentally non-...
