Sample records for alpha-bearing wastes

  1. Conditioning of alpha bearing wastes

    International Nuclear Information System (INIS)

    Alpha bearing wastes are generated during the reprocessing of spent fuel, mixed oxide fuel fabrication, decommissioning and other activities. The safe and effective management of these wastes is of particular importance owing to the radiotoxicity and long lived characteristics of certain transuranic (TRU) elements. The management of alpha bearing wastes involves a number of stages which include collection, characterization, segregation, treatment, conditioning, transport, storage and disposal. This report describes the currently available matrices and technologies for the conditioning of alpha wastes and relates them to their compatibility with the other stages of the waste management process. The selection of a specific immobilization process is dependent on the waste treatment state and the subsequent handling, transport, storage and disposal requirements. The overall objectives of immobilization are similar for all waste producers and processors, which are to produce: (a) Waste forms with sufficient mechanical, physical and chemical stability to satisfy all stages of handling, transport and storage (referred to as the short term requirements), and (b) Waste forms which will satisfy disposal requirements and inhibit the release of radionuclides to the biosphere (referred to as the long term requirements). Cement and bitumen processes have already been successfully applied to alpha waste conditioning on the industrial scale in many of the IAEA Member States. Cement systems based on BFS and pozzolanic cements have emerged as the principal encapsulation matrices for the full range of alpha bearing wastes. Alternative technologies, such as polymers and ceramics, are being developed for specific waste streams but are unlikely to meet widespread application owing to cost and process complexity. The merits of alpha waste conditioning are improved performance in transport, storage and disposal combined with enhanced public perception of waste management operations. These

  2. Solidification of alpha-bearing wastes in a ceramic matrix

    International Nuclear Information System (INIS)

    At the Karlsruher Nuclear Resaerch Center ceramic materials are evaluated as a matrix for alpha.bearing wastes, i.e. dissolver residues from reprocessing, liqiud alpha-cencentrates, ashes and residues from the acid digestion process. Included in these experiments were α-containing sudgles as they are generated by the separation of the active species from MLW-concentrates. Caoline, clay, feldspar and quartz are selected as teh raw materials as in the ceramic industry. (orig./RB)

  3. Status of high level and alpha bearing waste management in PNC

    International Nuclear Information System (INIS)

    For completing the nuclear fuel cycle in Japan, Power Reactor and Nuclear Fuel Development Corporation (PNC) has a role to promote the management of high level and alpha bearing wastes. For high level waste management, it is planned in Japan to initiate the operation of a vitrification pilot plant by 1987 for the development of the solidification process, and to make it possible to initiate trial disposal by 2015 for the development of geological disposal technology. In PNC, monolithic borosilicate glass was selected as the final form of solidification. Alpha bearing wastes have been produced in the mixed oxide fuel fabrication facility and the reprocessing plant in PNC; and the amount should increase considerably in the future in Japan. About these two areas of waste management, the policy and the research/development programs are described. (J.P.N.)

  4. The assay of encapsulated alpha-bearing waste: feasibility study

    International Nuclear Information System (INIS)

    This report contains a review of potentially applicable techniques for the determination of actinide isotopes in radioactive waste and a summary of results obtained with various prototype instruments. A schematic design of a complete assay station is derived with consideration given to practical aspects like remote handling, maintenance etc. and recommendations for further work are made. The place of waste assay in the overall quality assurance of packaged waste is also considered. (author)

  5. Decontamination of alpha-bearing solid wastes and plutonium recovery

    International Nuclear Information System (INIS)

    Nuclear activities in the Radiochemistry building of Fontenay-aux-Roses Nuclear Research Center concern principally the study of fuel reprocessing and the production of transuranium isotopes. During these activities solid wastes are produced. In order to improve the management of these wastes, it has been decided to build new facilities: a group of three glove-boxes named ELISE for the treatment of α active solid waste and a hot-cell, PROLIXE, for the treatment of solid wastes. Leaching processes were developed in order to: decontaminate these wastes and recover actinide elements, particularly the highly valuable plutonium, from the leachates. The processes developed are sufficiently flexible to be able to accommodate solid wastes produced in other facilities. Laboratory studies were conducted to develop the leaching process based on the use of electrogenerated Ag(II) species which is particularly suitable to provoke the dissolution of PuO2. Successful exhaustive Pu decontaminations with DF(Pu) higher than 104 were achieved for the first time during the treatment of stainless steel PuO2 cans (future MELOX plant) by electrogenerated Ag (II) in nitric acid medium

  6. Options for the decontamination of alpha-bearing liquid wastes

    International Nuclear Information System (INIS)

    This document reviews the processes potentially available, and their state of development, for the removal of alpha activity from aqueous waste streams. In present practice, most such streams are treated by precipitation, usually with an iron hydroxide, but the potential role and limitations of other precipitants, of ion exchange techniques and solvent extraction are also discussed as well as newer electrochemical methods. Because of the importance of precipitation, and the fact the α-activity often occurs in suspended form in wastes, the methods for solids separation and concentration are considered in some detail, together with other physical processes such as evaporation. The equipment and operational aspects are also discussed, particularly for precipitation, ion exchange and solvent extraction treatments. The conclusions relate to an extensive table in which the different methods are compared. The optimum treatment or combination of treatments will depend on the waste stream and other circumstances (particularly on the chemical and radiological constituents of the waste, and its rate of arising) and the aim of this work is to give an initial guide to the choice among the options.

  7. Controlled-air incineration of alpha-bearing solid wastes

    International Nuclear Information System (INIS)

    The Los Alamos Scientific Laboratory is completing a study of controlled-air incineration (CAI) as a technique for volume reduction and stabilization of combustible transuranic-contaminated solid wastes. To demonstrate feasibility, a process has been assembled and operated on synthetic and contaminated combustibles. This paper summarizes the CAI project history, process design, provisions for radioactive operation, experimental results to date, and future plans. Achievements include operation at the design feed rate as well as combustion of separate feed compositions including cellulosics, polyethylene, polyvinyl chloride (PVC) and latex rubber. Refractory life has been satisfactory to date, with studies continuing. The offgas cleanup system has proven to be extremely effective; the final high-efficiency filters showing virtually no pressure drop increase. The ability of the system to process high concentrations of PVC has been demonstrated with no chloride-induced degradation detected. Chloride and sulfate removal from the offgas has been excellent with concentrations reaching 8 and 10 ppM maximum, respectively, in the process condensate

  8. Developments in the treatment of solid alpha-bearing wastes at the PNC plutonium fuel facilities

    International Nuclear Information System (INIS)

    Some results of experiments done in PNC are presented on volume reduction technics for alpha-bearing wastes. A pilot wood milling machine automatically mills the plywood frames of nipple connected HEPA filters, which result in fine sized wooden chips, two nipples and the filter components. The filter components are melted in an induction furnace to be homogeneous solids. These methods and incineration of wooden chips reduce the stored volume of HEPA filters to 1/50 -- 1/100. PVC and neoprene rubber are decomposed in concentrated sulfuric acid, followed by oxidation with nitric acid. The acid digestion process generates chlorine-rich gas, from which only chlorine is selectively absorbed in water. An alpha-bearing vessel and a glovebox are cut at their installed places without spread of plutonium contamination outside the greenhouses. (auth.)

  9. Geological disposal of spent fuel and high level and alpha bearing wastes

    International Nuclear Information System (INIS)

    The International Symposium on Geologic Disposal of Spent Fuel, High Level and Alpha Bearing Wastes, organized jointly with the Commission of the European Communities and the OECD Nuclear Energy Agency, was held in Antwerp, Belgium, from 19 to 23 October 1992. The symposium was attended by nearly two hundred participants from 25 countries and four international organizations. There were 35 oral presentations of papers and 20 poster papers related to the symposium theme: progress towards the demonstration of safe disposal. Seven technical sessions dealt with: progress in programmes of international organizations; progress in site characterization programmes and methods; progress in repository design concepts, construction techniques and engineered barrier design; high level and alpha bearing waste characterization and waste acceptance; repository concepts for direct disposal of spent fuel; progress in developing, testing and validating repository performance assessment models; and progress in national and international programmes for disposal. The technical presentations addressed disposal in all the principal geological media currently under consideration: clay, crystalline rock, salt and volcanic tuff to achieve the objectives of safe final disposal.

  10. Siting, design and construction of a deep geological repository for the disposal of high level and alpha bearing wastes

    International Nuclear Information System (INIS)

    The main objective of this document is to summarize the basic principles and approaches to siting, design and construction of a deep geological repository for disposal of high level and alpha bearing radioactive wastes, as commonly agreed upon by Member States. This report is addressed to decision makers and technical managers as well as to specialists planning for siting, design and construction of geological repositories for disposal of high level and alpha bearing wastes. This document is intended to provide Member States of the IAEA with a summary outline for the responsible implementing organizations to use for siting, designing and constructing confinement systems for high level and alpha bearing radioactive waste in accordance with the protection objectives set by national regulating authorities or derived from safety fundamentals and standards of the IAEA. The protection objectives will be achieved by the isolation of the radionuclides from the environment by a repository system, which consists of a series of man made and natural safety barriers. Engineered barriers are used to enhance natural geological containment in a variety of ways. They must complement the natural barriers to provide adequate safety and necessary redundancy to the barrier system to ensure that safety standards are met. Because of the long timescales involved and the important role of the natural barrier formed by the host rock, the site selection process is a key activity in the repository design and development programme. The choice of the site, the investigation of its geological setting, the exploration of the regional hydrogeological setting and the primary underground excavations are all considered to be part of the siting process. 16 refs

  11. Guidelines for the operation and closure of deep geological repositories for the disposal of high level and alpha bearing wastes

    International Nuclear Information System (INIS)

    The operation and closure of a deep geological repository for the disposal of high level and alpha bearing wastes is a long term project involving many disciplines. This unique combination of nuclear operations in a deep underground location will require careful planning by the operating organization. The basic purpose of the operation stage of the deep repository is to ensure the safe disposal of the radioactive wastes. The purpose of the closure stage is to ensure that the wastes are safely isolated from the biosphere, and that the surface region can be returned to normal use. During these two stages of operation and closure, it is essential that both workers and the public are safely protected from radiation hazards, and that workers are protected from the hazards of working underground. For these periods of the repository, it is essential to carry out monitoring for purposes of radiological protection, and to continue testing and investigations to provide data for repository performance confirmation and for final safety assessment. Over the lengthy stages of operation and closure, there will be substantial feedback of experience and generation of site data. These will lead both to improved quality of operation and a better understanding of the site characteristics, thereby enhancing the confidence in the ability of the repository system to isolate the waste and protect future generations. 15 refs

  12. A review of methods for the decontamination of alpha-bearing waste streams to very low-levels of activity

    International Nuclear Information System (INIS)

    This report reviews the processes presently available for the decontamination of alpha-bearing waste effluents. Evaporation, chemical precipitation, organic and inorganic ion exchange, solvent extraction, ultrafiltration, electrical and microbiological processes are considered in turn. Each type of process and its applications in the nuclear industry are briefly described together with the results from any recent development studies. From the information available the advantages and limitations of the process for alpha removal to low-levels (10-2-10-3 Bq/msup(l)) are assessed. It is concluded that no single process is capable of removing the actinides to these very low levels but that this level of decontamination should be achieved by the use of two or more processes either sequentially or in combination; e.g. the use of ultrafiltration or precipitation processes in combination with finely divided inorganic ion exchange materials. Processes involving a good solid-liquid separation, such as ultrafiltration appear to be the most appropriate for actinides which show a tendency to hydrolyse and form colloids. However, there is very limited information available on the removal of actinides by such processes, particularly at levels < Bq/ml. Electrical and biological processes are not yet sufficiently developed for their potential to be properly assessed. (author)

  13. Pacoma: Performance assessment of the confinement of medium-active and alpha-bearing wastes. Assessment of disposal in a clay formation in the United Kingdom

    International Nuclear Information System (INIS)

    This report describes the PACOMA assessment of the radiological impact of disposal of intermediate level and alpha-bearing wastes in a hypothetical repository situated in the clay formations below the Harwell site in the United Kingdom. The assessment includes: best estimate calculations, uncertainty analyses, sensitivity analyses and model comparisons. Results of the radiological impact calculations are in the form of doses and risks to individuals and time-integrated doses to populations, for a normal evolution scenario and a number of altered evolution scenarios. The calculated risks to individuals are well below the limit recommended by the ICRP, and the calculated collective dose over the first 10,000 years after disposal is zero. Thus the radiological impact of the disposal intermediate level and alpha-bearing wastes in a clay formation is predicted to be small. The uncertainty analyses showed that, for the normal evolution scenario, the range of predicted risks to individuals is very wide. However, these results must be treated with caution because a formal methodology for eliciting judgments about model parameter values was only applied in the case of geosphere data. The sensitivity analyses and model comparisons indicated the need for improved models and data for water and radionuclide movement in the near-surface environment

  14. Design of alpha bearing industrial waste processing facility associated with a nuclear fuel fabrication plant: incineration and ashes containment

    International Nuclear Information System (INIS)

    As part of a COGEMA project for the construction of a mixed oxide nuclear fuels production plant (UPu)O2 to be used for the recycling of plutonium in light water reactors, COGEMA, USSI and the AEC (CEA) present the main options decided upon for the creation of a treatment and embedding unit for the wastes which will be produced by the plant from 1993 onwards. A 15 kg.h-1 capacity incinerator capable of processing 420 m3.year-1 of alpha solid technological wastes is described. This description is completed by information concerning the research and development program adopted by the CEA for incineration, recovery of Pu in the ashes and the embedding of incineration ashes. An initial estimate is made of the volume reduction factor achieved by incineration (ratio of the volume of waste before incineration to the volume of embedded products)

  15. Oxidative degradation of spent ion-exchange resins and alpha-bearing wastes in aqueous medium

    International Nuclear Information System (INIS)

    Different treatment processes of spent ion-exchange resins aiming at volume reduction are under development or on fullscale operation. A new volume reduction technique for treatment of ion-exchange resin materials was developed using hydrogen peroxide as oxidizing agent in presence of catalyst. Details information for this technique is introduced in this report. A newly developed simple and economically attractive technique for oxidative decomposition of spent ion-exchange resins was studied aiming at achieving remarkable volume and weight reduction. Different factors affecting semi-continuous oxidative degradation process e.g. effect of addition rate of oxidant, pH value, grain size of resin as well as type and concentration of catalyst were studied, keeping the reaction time and weight of resins constant for both cationite and anionite forms. In conclusion, the oxidative degradation of ion-exchange resin in aqueous medium could be considered as a very attractive process. (M.N.)

  17. The European Communities R and D actions on alpha waste

    International Nuclear Information System (INIS)

    Since 1973 R and D programmes on Management and Disposal of Radioactive Wastes are being carried out by the EC. Work related directly to alpha-bearing waste from reprocessing and Pu O/sub 2//UO/sub 2/ fuel fabrication constitutes a significant part in these programmes. The paper gives an overview of these research subjects, which include actinide recovery from HLW and Medium Level Waste, alpha-monitoring, Long-term risk assessment and waste disposal, the development of treatment processes for solid wastes and characterization of conditioned alpha-bearing waste products

  18. Policy and practice of radioactive waste management in India

    International Nuclear Information System (INIS)

    The Indian program on radioactive waste management comprising two main variants: engineering subsurface repositories for low- and intermediate-level wastes and deep geological formations for alpha-bearing and high-level wastes (HLW) is presented. One of the problems deals with the matrices with improved properties for HLW inclusion. The other aspect concerns development of management with alpha-emitting radionuclides in HLW. Special attention is paid to the problems of safety

  19. Incineration of technological waste contaminated with alpha emitters

    International Nuclear Information System (INIS)

    A large R and D programme is in progress at the CEA on alpha-bearing waste incineration. The program is developed in the laboratory and a pilot plant including the following aspects: physico-chemical characterization of wastes, study of thermal decomposition of wastes, laboratory study of generated gases (first with inactive then with active wastes), development of an industrial pilot plant with inactive wastes, study of corrosion resistance of material (laboratory and pilot plant), study and qualification of nuclear measurements on wastes, ashes and equipment

  20. Electron microscopy of phase and microstructure development in aluminum silicate ceramics for the immobilization of transuranium element containing wastes

    International Nuclear Information System (INIS)

    At the Institute for Nuclear Waste Technology (INE) with the Karlsruhe Nuclear Research Center (KfK) ceramic materials were evaluated as matrices for the solidification of radioactive alpha-bearing wastes. A suitable ceramic material, KAB 78, which is prepared from the raw materials kaolin, bentonite, and corundum, was examined with and without waste-simulating oxides. Applied methods were X-ray powder diffraction, scanning electron microscopy and transmission electron microscopy, both in combination with energy dispersive X-ray microanalysis. The effects of the sintering conditions and of the waste materials' nature are revealed and discussed. (orig.)

  1. Operational experiences and upgradation of waste management facilities Trombay, India

    International Nuclear Information System (INIS)

    /disposed at RSMS. Based on categories of solid wastes three types of engineered containments are in use at RSMS. They are Stone Lined Earth Trenches, Reinforced Concrete Trenches and Tile holes. Details of radioactive waste both liquid and solid, their sources, collection, transportation, storage, decontamination, conditioning and disposal is presented in the paper. Brief description of special wastes like spent organic organic solvent (TBP and dodecane) hydraulic oils and alpha bearing chemical waste is also given. Waste Management Facilities Trombay were set up in early sixties. Now efforts are being made to do the facility upgradation. Main objective of facility upgradation, besides safety enhancement, is to reduce exposure to working personnel and improved plant performance with respect to decontamination, conditioning and disposal of waste keeping in view ALARA principle. Facility upgradation is being achieved by revamping the existing facilities and augmentation by introducing latest processes and technologies. In the field of liquid waste management, waste receiving and storage system have been revamped. Waste treatment system comprising of chemical treatment and ion exchange treatment is being replaced by caesium specific non regenerative type ion exchanger instead of vermiculite ion exchange system and introduction of sludge blanket clarifier for very low level waste treatment. Decontamination of reactor equipment and protective wears has been totally revamped. In the field of solid waste management a number of new system have been introduced such as waste assaying, waste segregation, drum pelletisation and filter compaction, spent resin immobilization and handling of spent sealed sources. Details of all these improvements are presented in the paper including new designs of engineered barriers. Developmental work in radiological laboratories in the field of fuel fabrication leads to generation of alpha bearing solid waste not amenable to disposal in near surface

  2. Advanced solvent extraction and ion-exchange processes for the treatment of low and medium level liquid waste

    International Nuclear Information System (INIS)

    Exhaustive decontamination of three important heat generating and/or alpha bearing liquid wastes for decategorization purposes was investigated through the implementation of neutral bifunctional or macrocyclic extractants (CMPO or crown-ethers) using liquid-liquid solvent extraction, supported liquid membranes or extraction chromatography techniques. Suspended bed columns filled with very specific inorganic ion exchangers like ammonium molybdophosphate were also tested. Improvement of volume reduction techniques for radioactive liquid waste focused on the development and scaling-up of electrochemical ion exchange which demonstrated good capabilities to treat a wide range of radioactive liquid wastes

  3. Waste treatment in NUCEF facility with silver mediated electrochemical oxidation technique

    International Nuclear Information System (INIS)

    Silver mediated electrochemical oxidation technique has been considered one of promising candidates for alpha-bearing waste treatment. Destruction tests of organic compounds, such as insoluble tannin, TBP and dodecane, were carried out by this technique and the experimental data such as destruction rates, current efficiencies and intermediates were obtained. These compounds could be completely mineralized without the formation of reactive organic nitrate associated to safety hazards. On the basis of these results, the applicability of silver mediated electrochemical oxidation technique to waste treatment in NUCEF was evaluated. (authors)

  4. Economic and technical advantages of high temperature processes in high level radioactive waste management

    International Nuclear Information System (INIS)

    The estimated waste management costs incurred for the three principal waste forms produced by reprocessing spent fuel are compared from a theoretical economic standpoint. The cost of vitrifying concentrated fission product solutions is considered first, together with the estimated additional costs of transportation and final storage in a geological repository. Fuel cladding waste treatments are then examined by comparing the relative costs of cementation, compaction and melting; processes for disposal of incinerable alpha-bearing wastes are also considered. In each case, the processes ensuring the greatest waste volume reduction not only result in the lowest management cost, but are also most effective in ensuring the highest possible containment quality for the final waste package

  5. Oxygen incineration process for treatment of alpha-contaminated wastes

    International Nuclear Information System (INIS)

    As a part of development of a treatment technology for burnable alpha-bearing (or -contaminated) wastes using an oxygen incineration process, which would be expected to produce in Korea, the off-gas volume and compositions were estimated form mass and heat balance, and then compared to those of a general air incineration process. A laboratory-scale oxygen incineration process, to investigate a burnable wastes from nuclear fuel fabricatin facility, was designed, constructed, and then operated. The use of oxygen instead of air in incineratin would result in reduction on off-gas product below one seventh theoretically. In addition, the trends on incineration and melting processes to treat the radioactive alpha-contaminated wastes, and the regulations and guide lines, related to design, construction, and operation of incineration process, were reviewed. Finallu, the domestic regulations related incineration, and the operation and maintenance manuals for oxy-fuel burner and oxygen incineration process were shown in appendixes

  6. Qualitative acceptance criteria for radioactive wastes to be disposed of in deep geological formations

    International Nuclear Information System (INIS)

    The present Safety Guide has to be seen as a companion document to the IAEA Safety Series No. 99. It is concerned with the waste form which is an important component of the overall disposal system. Because of the broad range of waste types and conditioned forms and variations in the sites, designs and constructional approaches being considered for deep geological repositories, this report necessarily approaches the waste acceptance criteria in a general way, recognizing that the assignment of quantitative limits to these criteria has to be the responsibility of national authorities. The main objective of this Safety Guide is to set out qualitative waste acceptance criteria as a basis for specifying quantitative limits for the waste forms and packages which are intended to be disposed of in deep geological repositories. It should serve as guidance for assigning such parameter values which would fully comply with the safety assessment and performance of a waste disposal system as a whole. This document is intended to serve both national authorities and regulatory bodies involved in the development of deep underground disposal systems. The qualitative waste acceptance criteria dealt with in the present Safety Guide are primarily concerned with the disposal of high level, intermediate level and long-lived alpha bearing wastes in deep geological repositories. Although some criteria are also applicable in other waste disposal concepts, it has to be borne in mind that the set of criteria presented here shall ensure the isolation capability of a waste disposal system for periods of time much longer than for other waste streams with shorter lifetimes. 51 refs, 1 tab

  7. Waste disposal concept in a tertiary clay formation

    International Nuclear Information System (INIS)

    Investigations on the suitability of tertiary clay layer as host formation for disposal of conditioned high-level and alpha bearing radioactive waste were started in Belgium in the mid-seventies. On the basis of results obtained from preliminary field and laboratory research it was possible at the end of the seventies to elaborate a first rough outline of an underground facility for final emplacement of the waste concerned. Excellent retention capacity for most of the long-lived radionuclides and low hydraulic conductivity are found in the Boom clay formation in the investigated area. In the early stage of the program, however, uncertainties remained about the possibility of creating galleries at reasonable depth in clay at an acceptable cost price. Therefore, the decision was taken in 1978 to build an underground laboratory in order to investigate, among others, the geotechnical properties and the minability of the Boom clay. A satisfactory reproduction of three years of in-situ measurements was obtained by using an elasto-viscoplastic model with strain softening. The main conclusion of this R and D program, is that tunneling capabilities at reasonable cost prices in deep laying Boom clay have been demonstrated

  8. Decontamination of alpha contaminated metallic waste by cerium IV redox process

    International Nuclear Information System (INIS)

    Management of alpha-contaminated metallic waste is of particular concern because of its long term radio toxicity and need for its disposal in expensive deep geological repository in suitably conditioned form. A novel chemical decontamination technique is developed for decontamination of those waste based on ceric/cerous redox cyclic process in nitric acid medium. Presently, the alpha-bearing metallic wastes are kept in transit storage facilities under surveillance pending their ultimate disposal. It is highly advantageous to decontaminate these wastes into non-alpha category and dispose them off in conditioned form in NSDF. In this work a novel chemical decontamination technique based on ceric/cerous redox cyclic process in nitric acid medium is demonstrated on laboratory scale. Ozone has been employed for regeneration of cerous ions to the cyclic process. The ceric ion attacks the metal surface, layer by layer, on account of its powerful oxidizing property, thereby decontaminating the metallic surface. The actinide oxides (PuO2) dissolve in nitric medium by oxidative reaction mechanism

  9. Extraction-wet oxidation process using sulphuric acid for treatment of TBP-dodecane wastes

    International Nuclear Information System (INIS)

    In the nuclear fuel reprocessing plants, 30% n-tributyl phosphate in hydrocarbon diluent is used for extraction of uranium and plutonium from the spent fuel by Purex process. When TBP-dodecane can no longer be purified from its degradation products, it is discarded as alpha bearing, intermediate level wastes containing plutonium and ruthenium-106. To overcome shortcomings of extraction-pyrolysis and saponification processes, studies were undertaken to find the suitability of H2SO4 as an alternative extractant for TBP. Oxidation of TBP to H3PO4 using H2O2 was also explored as H3PO4 can be treated by known procedures for removal of plutonium and ruthenium-106. The experiments were conducted with aged spent solvent wastes discharged from reprocessing plant at Trombay using H2SO4 and H2SO4 - H3PO4 mixture. The decontamination factors (DFs) for alpha activity were found to be satisfactory. The DFs for ruthenium were lower as compared to those obtained in experiments with simulated degraded waste. The gas chromatographic analysis of separated diluent revealed high branched alkane content and low n-dodecane content of separated diluent. It is very much different from that of diluent currently in use. Hence incineration of separated diluent is recommended. (author)

  11. Site investigations for repositories for solid radioactive wastes in deep continental geological formations

    International Nuclear Information System (INIS)

    This report reviews the earth-science investigations and associated scientific studies that may be needed to select a repository site and confirm that its characteristics are such that it will provide a safe confinement for solidified high-level and alpha-bearing and certain other solid radioactive wastes. Site investigations, as used in this report, cover earth sciences and associated safety analyses. Other site-investigation activities are identified but not otherwise considered here. The repositories under consideration are those consisting of mined cavities in deep continental rocks for accepting wastes in the solid and packaged form. The term deep as used in this report is used solely to emphasize the distinction between the repositories discussed in this report and those for shallow-ground disposal. In general, depths under consideration here are greater than 200 metres. The term continental refers to those geological formations that occur either beneath present-day land masses and adjoining islands or beneath the shallow seas. One of the objectives of site investigations is to collect the site-specific data necessary for the different evaluations, such as modelling required to assess the long-term safety of an underground repository

  14. Guidance for regulation of underground repositories for disposal of radioactive wastes

    International Nuclear Information System (INIS)

    Deep geological formations are favoured for disposal of high level and alpha bearing wastes from the nuclear fuel cycle: varying depths of emplacement, including shallow land disposal, with or without engineered barriers may be foreseen for low and intermediate level wastes. Most countries will regulate such disposal through licensing actions by a regulatory body whose purpose is to review and analyse the safety of all stages of the disposal programme. This regulatory function may be performed either by a single national authority or a system of authorities. It is the intent of the IAEA that this publication will be used as a guide to develop regulatory requirements for licensing waste disposal facilities. This report updates IAEA Safety Series No. 51. Development of the regulatory process is maturing rapidly in Member States, hence there is a clear need to revise the nearly ten year old text of that publication. The purpose of this report is to provide general guidance for the regulation of underground disposal of low, intermediate and high level radioactive wastes once a fundamental decision to pursue this option has been made. It is intended to reflect the experience of those countries with mature regulatory programmes and to provide some guidance to those countries that wish to develop regulatory programmes. Guidance is given on what issues should be addressed in the licensing review, what decision points are important, and what guidance should be given to the applicant by the regulatory system in the course of the licensing actions. The orientation of the report is on technical factors rather than the social and political aspects that need to be taken into account when regulating the underground disposal of radioactive wastes. The financing aspects are not discussed

    Residential waste comes from residential areas with multi-family and single-family housing and includes four types of waste: household waste, garden waste, bulky waste and household hazardous waste. Typical unit generation rates, material composition, chemical composition and determining factors...... are discussed in this chapter. Characterizing residential waste is faced with the problem that many residences already divert some waste away from the official collection systems, for example performing home composting of vegetable waste and garden waste, having their bundled newspaper picked up by...... the scouts twice a year or bringing their used furniture to the flea markets organized by charity clubs. Thus, much of the data available on residential waste represents collected waste and not necessarily all generated waste. The latter can only be characterized by careful studies directly at the...

    The dangers and problems of hazardous wastes are described in this pictorial booklet that is part of the EPA solid waste management publication series. It is shown that how the nation's hazardous wastes are managed or mismanaged is a crucial environmental issue with vast implications for public health and for the integrity of the ecological systems on which man depends. The environmental folly of dumping or burning these wastes is emphasized, along with the economic imprudence of continuing to throw away valuable resources as wastes. The public as well as industry must pay the costs of safe hazardous waste management

  19. Development of regulatory procedures for the disposal of solid radioactive waste in deep, continental formations

    International Nuclear Information System (INIS)

    For the disposal of radioactive waste, and in particular, of the high-level and alpha-bearing waste from the nuclear fuel cycle, the most favoured solution in most countries is disposal in deep, continental geological formations. Commitment to this disposal method involves a number of issues related to the various stages of the disposal programme which must be addressed through some reasoned decision-making process. Most countries are opting for regulating such a programme through licensing actions by a body whose purpose is to review, certify and ensure the safety of all the stages of the disposal programme. This regulatory body may either be one single national authority or a system of authorities designated by the government. The key to such regulation is the set of procedures, determined in advance, for the actions of the implementing organization, the review by the regulatory body and the involvement of other parties. This document concerns itself with the procedures which could logically be followed in reaching a set of rational decisions by the regulatory body. Care in the preparation and application of such procedures is an important element in the acceptability of the concept, the site and the other aspects of the disposal programme. The intention of this document is to give guidance as to what issues should be addressed in the licensing review, what decision points are important, and what guidance should be given to the applicant by the regulatory body in the course of the licensing actions. The procedures are keyed to be designed according to the logical steps involved in the development and operation of the repository. However, the document does not pretend to give guidance regarding the optimal interactions between the implementing organization and the regulatory body. This document is oriented to the disposal of solid radioactive waste in deep, continental geological formations using mining techniques

  3. Waste incineration

    International Nuclear Information System (INIS)

    Waste incineration can be defined as the thermal conversion processing of solid waste by chemical oxidation. The types of wastes range from solid household waste and infectious hospital waste through to toxic solid, liquid and gaseous chemical wastes. End products include hot incineration gases, composed primarily of nitrogen, carbon dioxide, water vapor and to a smaller extend of non-combustible residue (ash) and air pollutants (e. g. NOx). Energy can be recovered by heat exchange from the hot incineration gases, thus lowering fossil fuel consumption that in turn can reduce emissions of greenhouse gases. Burning of solid waste can fulfil up to four distinctive objectives (Pera, 2000): 1. Volume reduction: volume reduction of about 90 %, weight reduction of about 70 %; 2. Stabilization of waste: oxidation of organic input; 3. Recovery of energy from waste; 4. Sanitization of waste: destruction of pathogens. Waste incineration is not a means to make waste disappear. It does entail emissions into air as well as water and soil. The generated solid residues are the topic of this task force. Unlike other industrial processes discussed in this platform, waste incineration is not a production process, and is therefore not generating by-products, only residues. Residues that are isolated from e. g. flue gas, are concentrated in another place and form (e. g. air pollution control residues). Hence, there are generally two groups of residues that have to be taken into consideration: residues generated in the actual incineration process and others generated in the flue gas cleaning system. Should waste incineration finally gain public acceptance, it will be necessary to find consistent regulations for both sorts of residues. In some countries waste incineration is seen as the best option for the treatment of waste, whereas in other countries it is seen very negative. (author)

  6. Nuclear waste

    International Nuclear Information System (INIS)

    Radioactive waste at U.S. nuclear power plants is mounting at a rate of more than 2,000 metric tons a year. Yet the Department of Energy (DOE) does not expect a geologic repository to be available before 2010. In response to concerns about how best to store the waste until a repository is available, GAO reviewed the alternatives of continued storage at utilities' reactor sites or transferring waste to a monitored retrievable storage facility. This paper assesses the likelihood of a monitored retrievable storage facility operating by 1990, legal implications if DOE is unable to take delivery of wastes in 1998, propriety of using the Nuclear Waste Fund from which DOE's waste program costs are paid to pay utilities for on-site storage capacity added after 1998, the ability of utilities to store their waste on-site until a repository is operating, and relative costs and safety of the two storage alternatives

    International Nuclear Information System (INIS)

    This chapter present a brief overview of the current situation of siting radioactive wastes. This is followed by an overview of various psychological approaches attempting to analyse public reactions to nuclear facilities. It will be argued that public reactions to nuclear waste factilities must be seen in the context of more general attitudes toward nuclear energy. The latter are not only based upon perceptions of the health and environmental risks but are built on values, and sets of attributes which need not be similar to the representations o the experts and policy-makers. The issue of siting nuclear waste facilities is also embedded in a wider moral and political domain. This is illustrated by the importance of equity issues in siting radioactive wastes. In the last section, the implications of the present line of argument for risk communication and public participation in decisions about siting radioactive wastes will be briefly discussed.

  17. Updating of the performance assessments of the geological disposal of high-level and medium-level wastes in the Boom clay formation

    International Nuclear Information System (INIS)

    The objective of this report is to assess the performance of disposed medium-level and alpha-bearing waste in a geological repository in the Boom clay formation at the Mol site (Belgium). The results of this study are based on calculations that are in agreement with recent information on the Belgian nuclear programme and the corresponding waste arising. The applied methodology consists of two consecutive steps: (1) a scenario analysis in which relevant scenarios, leading to the exposure of man to radiation are selected, and (2) a consequence analysis in which potential radiological consequences of the exposure are evaluated. The scenario, selected in this study, is designated as the normal evolution scenario and comprises a normal evolution scenario in which the present conditions are assumed to last infinitely. The scenario is extended with a climatic change, a secondary glaciation effects, and a faulting scenario. The applied consequence analysis consists in deterministic and stochastic calculations, which are are complementary. Three pathways of radionuclides to man were considered: (1) the discharge of contaminated groundwater into rivers or (2) into agricultural soils, and (3) the sinking of a water well into the aquifer that overlies the host formation. Calculations indicate that most radionuclides decay within the first metres of the clay barrier. The fission and activation products 14C, 129I, 79Se, 99Tc, 107Pd, 93Zr, and 135Sr as well as some actinides of the 237Np and uranium decay series can however reach the biosphere. The maximum dose rates for high-level waste, fuel cladding, medium-level, and iodine waste were calculated. Deterministic calculations indicate that the maximum dose rates are attained via the water well pathway for the case of the climatic change scenario. (A.S.)

  19. Waste segregation

    International Nuclear Information System (INIS)

    A scoping study has been undertaken to determine the state-of-the-art of waste segregation technology as applied to the management of low-level waste (LLW). Present-day waste segregation practices were surveyed through a review of the recent literature and by means of personal interviews with personnel at selected facilities. Among the nuclear establishments surveyed were Department of Energy (DOE) laboratories and plants, nuclear fuel cycle plants, public and private laboratories, institutions, industrial plants, and DOE and commercially operated shallow land burial sites. These survey data were used to analyze the relationship between waste segregation practices and waste treatment/disposal processes, to assess the developmental needs for improved segregation technology, and to evaluate the costs and benefits associated with the implementation of waste segregation controls. This task was planned for completion in FY 1981. It should be noted that LLW management practices are now undergoing rapid change such that the technology and requirements for waste segregation in the near future may differ significantly from those of the present day. 8 figures

    Radioactive waste is mounting at U.S. nuclear power plants at a rate of more than 2,000 metric tons a year. Pursuant to statute and anticipating that a geologic repository would be available in 1998, the Department of Energy (DOE) entered into disposal contracts with nuclear utilities. Now, however, DOE does not expect the repository to be ready before 2010. For this reason, DOE does not want to develop a facility for monitored retrievable storage (MRS) by 1998. This book is concerned about how best to store the waste until a repository is available, congressional requesters asked GAO to review the alternatives of continued storage at utilities' reactor sites or transferring waste to an MRS facility, GAO assessed the likelihood of an MRSA facility operating by 1998, legal implications if DOE is not able to take delivery of wastes in 1998, propriety of using the Nuclear Waste Fund-from which DOE's waste program costs are paid-to pay utilities for on-site storage capacity added after 1998, ability of utilities to store their waste on-site until a repository is operating, and relative costs and safety of the two storage alternatives

    International Nuclear Information System (INIS)

    Focusing on radioactive waste management and disposal policies in the United Kingdom, Sweden and the Federal Republic of Germany, this book gives a detailed historical account of the policy process in these three countries, and draws out the implications for theory and public policy. This comparative approach underlines how profoundly different the policy process has been in different countries. By comparing the evolution of policy in three countries, fundamental questions about the formation and resolution of technical decisions under uncertainty are clarified. The analysis of nuclear strategy, the politics of nuclear power, and the shifting emphasis of government regulation redefines the issue of radwaste management and sets it at the heat of the current debate about power, the environment and society. The combination of up-to-date technological assessment with an account of the social and political implications of radwaste management makes'Radioactive Waste'particularly useful to students of environmental studies, geography and public administration.

    International Nuclear Information System (INIS)

    DOE estimates that disposing of radioactive waste from civilian nuclear power plants and its defense-related nuclear facilities could eventually end up costing $32 billion. To pay for this, DOE collects fees from utilities on electricity generated by nuclear power plants and makes payments from its defense appropriation. This report states that unless careful attention is given to its financial condition, the nuclear waste program is susceptible to future shortfalls. Without a fee increase, the civilian-waste part of the program may already be underfunded by at least $2.4 billion (in discounted 1988 dollars). Also, DOE has not paid its share of cost-about $480 million-nor has it disclosed this liability in its financial records. Indexing the civilian fee to the inflation rate would address one major cost uncertainty. However, while DOE intends to do this at an appropriate time, it does not use a realistic rate of inflation as its most probable scenario in assessing whether that time has arrived

    The Department of Energy plans to award a contract to Bechtel Systems Management, Inc. to manage and operate the federal government's nuclear waste repository. The proposed management and operating contract is likely to substantially affect program operations and costs. This paper reports on a GAO report. A major concern is the degree to which the selected contractor might replace, or possibly duplicate, the efforts now being carried out by DOE's current contractors. It is questionable whether the contract will result in a more efficient and effective program. DOE officials have had to divert their attention from program operations to develop the contract proposal and participate in legal proceedings related to a bid protest. GAO and the DOE inspector general have reported on problems and issues involving DOE's administration of management and operating contracts, including some companies which participate in the nuclear waste program. Many of the resulting recommendations have yet to be implemented. Implementation of these recommendations could help ensure that the nuclear waste program is operated in a more cost-effective manner

    Full text: Waste Management (WM) has become an applied science. It is used at the point of generation, at the centralized treatment facilities, and at the disposal sites. In the government and private sector, much research is being done in waste by-product utilization. Some of the important factors that affect waste are sources of waste, classification of waste, waste treatment and conditioning, minimization of waste, laws and regulations governing waste and present and future issues. WM has become a career with a promising future as the cost of waste disposal increases tremendously. Scientists have started working on waste minimization and most organizations implement a formalized waste minimization program of their own. The waste disposal is approached in an analytical manner and this paper describes development in radioactive waste disposal and safe transportation practices

    There is an increasing need to couple environmental and economic considerations within waste management. Consumers and companies alike generate ever more waste. The waste-policy challenges of the future lie in decoupling growth in waste generation from growth in consumption, and in setting priorities for the waste management. This report discusses the criteria for deciding priorities for waste management methods, and questions the current principles of EU waste policies. The basis for the discussion is the so-called waste hierarchy which has dominated the waste policy in the EU since the mid-1970s. The waste hierarchy ranks possible methods of waste management. According to the waste hierarchy, the very best solution is to reduce the amount of waste. After that, reuse is preferred to recycling which, in turn, is preferred to incineration. Disposal at a landfill is the least favourable solution. (BA)

    International Nuclear Information System (INIS)

    While evoking the effects of radioactivity, this publication issued by religious authorities first presents the different radioactive wastes (low level, low or medium level and short life, medium level and long life, high level and long life) and indicates their respective origins. It proposes a brief overview of solutions adopted for the storage of high level-long life radioactive wastes in different countries. It presents the French political and regulatory framework for such storage, indicates the envisaged solutions (deep geological storage, separation and transmutation, packaging and long duration surface or underground warehousing), discusses the content of the debate which took place before the adoption of the law of June 2006, and evokes the notion of reversibility. The next part addresses issues related to public information, and evokes public opinion regarding this storage issue. Some other issues are then discussed within the Church's perspective: the responsibility towards future generations, the transmission of a secured heritage to future generations, the research effort, dialog and transparency

    Here are gathered 1)the decrees (99-686 and 99-687) of the 3 rd of August 1999 relative to the researches on radioactive waste management. A local committee of information and follow-up has to be established on the site of each underground facility. The composition of this committee is determined here (99-686). 3 people will from now on be jointly ordered by the Minister of Economy, Finance and Industry and by the Secretary of State of Industry to conduct a preliminary dialogue for the choice of one or several sites on which previous works should be made before the construction of an underground facility (99-687). They take the opinion of the people's representatives, the associations and the concerned population and inform the Ministers of Environment, Energy and Research of the collected information. 2)the decree of the 3 rd of August 1999 authorizing the 'Agence nationale pour la gestion des dechets radioactifs' (ANDRA) to install and exploit an underground facility located in Bure (Meuse) and intended to study the deep geological deposits where could be stored radioactive wastes.

    The Transpaille procedure is used for the recovery and processing of organic wastes using methane fermentation; gas and compost are produced. The system was installed at the slaughterhouse in Thies, Senegal, in 1988-89. It consists of a 40 cubic metres horizontal cylinder. The slaughterhouse produces 480 metric tonnes of wastes per year and 35.5 cubic metres of biogas per day at a process temperature of 31 deg C. Lagooning is used for the first time as a water purification technique at a slaughterhouse in West Africa. This technique reproduces the process by which water purifies itself biologically, by accelerating and controlling the phenomenon. The procedure includes pre-processing, a decanter/digester and three lagoons. The organic matter is degraded by bacteria, producing water, carbon dioxide and mineral elements, which are then assimilated by micro-algae and macrophytes (Pistia stratiotes). The tropical climate is convenient for this processing method, which is optimum of temperatures of between 25 deg C and 35 deg C. (authors).

  16. Nuclear waste

    International Nuclear Information System (INIS)

    The Department of Energy is awarding grants to the state of Nevada for the state's participation in DOE's program to investigate Yucca Mountain as a possible site for the disposal of civilian nuclear waste. This report has found that DOE's financial assistance budget request of $15 million for Nevada's fiscal year 1990 was not based on the amount the state requested but rather was derived by increasing Nevada's grant funds from the previous year in proportion to the increase that DOE requested for its own activities at the Nevada site. DOE's evaluations of Nevada's requests are performed too late to be used in DOE's budget formulation process because Nevada has been applying for financial assistance at about the same time that DOE submits its budget request to Congress

    There are two serious failures that arise in the management of solid waste. The first relates to the existence of negative externalities in the individual decision-making over waste generation and disposal. When individuals decide on how much to consume and what to consume, they do not take into account how much waste they produce. Because the external costs of waste generation (such as air and water pollution) are ignored by individuals, more waste is produced and disposed of than is sociall...

    Municipal solid waste (MSW) is a source of biomass material that can be utilized for bioenergy production with minimal additional inputs. MSW resources include mixed commercial and residential garbage such as yard trimmings, paper and paperboard, plastics, rubber, leather, textiles, and food wastes. Waste resources such as landfill gas, mill residues, and waste grease are already being utilized for cost-effective renewable energy generation. MSW for bioenergy also represents an opportunity to divert greater volumes of residential and commercial waste from landfills.

  14. Nuclear waste

    International Nuclear Information System (INIS)

    The state of Nevada opposed DOE's development of a nuclear waste repository at Yucca Mountain. As a result, disputes have arisen over how Nevada has spent financial assistance provided by DOE to pay the state's repository program costs. This report reviews Nevada's use of about $32 million in grant funds provided by DOE through June 1989 and found that Nevada improperly spent about $1 million. Nevada used as much as $683,000 for lobbying and litigation expenses that were unauthorized or were expressly prohibited by law, court decision, or grant terms; exceeded a legislative spending limit on socioeconomic studies by about $96,000; and used, contrary to grant terms, about $275,000 from one grant period to pay expenses incurred in the prior year. Also, Nevada did not always exercise adequate internal controls over grant funds, such as timely liquidation of funds advanced to contractors. A permissive approach to grant administration by DOE contributed to Nevada's inappropriate use of grant funds

The constructions can be roads, residential housing and nonresidential buildings. C&D waste has traditionally been considered without any environmental problems...... therefore should be managed accordingly. Another reason is that it has been documented that a large fraction of C&D waste (about 90 %) can be easily recycled and thus can conserve landfill capacity.

    International Nuclear Information System (INIS)

    Recognition of the importance of the safe management of radioactive waste means that, over the years, many well-established and effective techniques have been developed, and the nuclear industry and governments have gained considerable experience in this field. Minimization of waste is a fundamental principle underpinning the design and operation of all nuclear operations, together with waste reuse and recycling. For the remaining radioactive waste that will be produced, it is essential that there is a well defined plan (called a waste treatment path) to ensure the safe management and ultimately the safe disposal of radioactive waste so as to guarantee the sustainable long term deployment of nuclear technologies

    1988-03-01

    EPRI has conducted a number of studies to provide utilities with cost information on waste management for conventional wet scrubbing. Studies have characterized waste products; developed engineering designs for effective waste handling, disposal, and/or utilization; and estimated waste management costs. A study, completed in late 1986 evaluated spray dryer wastes. On a dollar-per-ton-disposed basis, spray dryer waste management costs were found to be higher than those for either conventional fly ash or scrubber sludge alone. Cost estimates for new and retrofit spray dryer applications must be revised upward from those produced earlier by EPRI.

  20. Public opinion and wastes

    International Nuclear Information System (INIS)

    This paper presents the results of a public opinion poll carried out in the French population and in the Electricite de France (EdF) staff population about nuclear wastes. Public anxiety about nuclear industry is mainly controlled by the accidents (Tchernobyl..) and the wastes generated by the nuclear power plants. Nuclear wastes, and chemical wastes, are firmly linked to the notion of risk but this risk remains abstract because most people have never seen nuclear wastes. Most people think that nuclear wastes remain a serious unsolved problem and would not accept to live in the vicinity of a waste storage center. In the EdF workers population anxiety is greater in the lower-salaried staff, but all consider that public information about nuclear wastes is insufficient. This poll confirms the necessity for an active communication policy about this topic. (J.S.). 16 tabs

    The Hanford Waste Vitrification Plant (HWVP) is being designed to immobilize pretreated Hanford high-level waste and transuranic waste in borosilicate glass contained in stainless steel canisters. Testing is being conducted in the HWVP Technology Development Project to ensure that adapted technologies are applicable to the candidate Hanford wastes and to generate information for waste form qualification. Empirical modeling is being conducted to define a glass composition range consistent with process and waste form qualification requirements. Laboratory studies are conducted to determine process stream properties, characterize the redox chemistry of the melter feed as a basis for controlling melt foaming and evaluate zeolite sorption materials for process waste treatment. Pilot-scale tests have been performed with simulated melter feed to access filtration for solids removal from process wastes, evaluate vitrification process performance and assess offgas equipment performance. Process equipment construction materials are being selected based on literature review, corrosion testing, and performance in pilot-scale testing. 3 figs., 6 tabs

  6. Mixed Waste Focus Area - Waste form initiative

    International Nuclear Information System (INIS)

    The mission of the US Department of Energy's (DOE) Mixed Waste Focus Area (MWFA) is to provide acceptable technologies that enable implementation of mixed waste treatment systems which are developed in partnership with end-users, stakeholders, tribal governments, and regulators. To accomplish this mission, a technical baseline was established in 1996 and revised in 1997. The technical baseline forms the basis for determining which technology development activities will be supported by the MWFA. The primary attribute of the technical baseline is a set of prioritized technical deficiencies or roadblocks related to implementation of mixed waste treatment systems. The Waste Form Initiative (WFI) was established to address an identified technical deficiency related to waste form performance. The primary goal of the WFI was to ensure that the mixed low-level waste (MLLW) treatment technologies being developed, currently used, or planned for use by DOE would produce final waste forms that meet the waste acceptance criteria (WAC) of the existing and/or planned MLLW disposal facilities. The WFI was limited to an evaluation of the disposal requirements for the radioactive component of MLLW. Disposal requirements for the hazardous component are dictated by the Resource Conservation and Recovery Act (RCRA), and were not addressed. This paper summarizes the technical basis, strategy, and results of the activities performed as part of the WFI

    The towns and cities have become the centres of population growth and require three essential services viz., water supply, waste water treatment and solid wastes disposal. The tremendous increase in population accelerates the amount of municipal solid waste (MSW) generation. Hence, the solid waste management (SWM) is one of the essential municipal services, to protect the environment, safeguard public health services and improve productivity.   In this context the case study is c...

  17. Solid waste combustion for alpha waste incineration

    International Nuclear Information System (INIS)

    Radioactive waste incinerator development at the Savannah River Laboratory has been augmented by fundamental combustion studies at the University of South Carolina. The objective was to measure and model pyrolysis and combustion rates of typical Savannah River Plant waste materials as a function of incinerator operating conditions. The analytical models developed in this work have been incorporated into a waste burning transient code. The code predicts maximum air requirement and heat energy release as a function of waste type, package size, combustion chamber size, and temperature. Historically, relationships have been determined by direct experiments that did not allow an engineering basis for predicting combustion rates in untested incinerators. The computed combustion rates and burning times agree with measured values in the Savannah River Laboratory pilot (1 lb/hr) and full-scale (12 lb/hr) alpha incinerators for a wide variety of typical waste materials

  8. Radioactive wastes management

    International Nuclear Information System (INIS)

    This article presents the French way to deal with nuclear wastes. 4 categories of radioactive wastes have been defined: 1) very low-level wastes (TFA), 2) low or medium-wastes with short or medium half-life (A), 3) low or medium-level wastes with long half-life (B), and 4) high-level wastes with long half-life (C). ANDRA (national agency for the management of radioactive wastes) manages 2 sites of definitive surface storage (La-Manche and Aube centers) for TFA-wastes. The Aube center allows the storage of A-wastes whose half-life is less than 30 years. This site will receive waste packages for 50 years and will require a regular monitoring for 300 years after its decommissioning. No definitive solutions have been taken for B and C wastes, they are temporarily stored at La Hague processing plant. Concerning these wastes the French parliament will have to take a decision by 2006. At this date and within the framework of the Bataille law (1991), scientific studies concerning the definitive or retrievable storage, the processing techniques (like transmutation) will have been achieved and solutions will be proposed. These studies are numerous, long and complex, they involve fresh knowledge in geology, chemistry, physics,.. and they have implied the setting of underground facilities in order to test and validate solutions in situ. This article presents also the transmutation technique. (A.C.)

  17. Vitreous ceramic waste form for waste immobilization

    International Nuclear Information System (INIS)

    Vitreous ceramic waste forms are being developed to complement glass waste forms in supporting DOE's environmental restoration efforts. The vitreous ceramics are composed of various metal oxide crystalline phases embedded in a silicate glass matrix. The vitreous ceramics are appropriate final waste forms for waste streams that contain large amounts of scrap metals and elements with low solubilities in glass, and have low-flux contents. Homogeneous glass waste forms are appropriate for wastes with sufficient fluxes and low metal contents. Therefore, utilization of both glass and vitreous ceramics waste forms will make vitrification technology applicable to the treatment of a much larger range of radioactive and mixed wastes. The controlled crystallization in vitreous ceramics resulted in formation of durable crystalline phases and durable residual glass matrix. The durable crystalline phases in vitreous ceramics included Ca3(PO4)2, magnetite (Fe2+Ni,Mn)Fe3+2O4, hibonite Ca(Al,Fe,Zr,Cr)12O19, baddeyelite ZrO2, zirconolite CaZrTi,O, and corundum Al2O3, which are thermodynamically more stable than normal glasses and are also less soluble in water than glasses. The durable glassy matrix in vitreous ceramics is due to the enrichment of silica and alumina during the crystallization process of vitreous ceramic formation. The vitreous ceramics showed exceptional long-term chemical durability and the processability of vitreous ceramics were also demonstrated at both bench- and pilot-scale. This paper briefly describes the use of vitreous ceramics for treating sample mixed wastes with high contents of either Cr, Fe, Zr, and Al, or alkalis

  18. Solid waste study

    International Nuclear Information System (INIS)

    The purpose of this document is to study the solid waste issues brought about by a Type C Investigation; ''Disposal of Inappropriate Material in the Los Alamos County Landfill'' (May 28, 1993). The study was completed in August 1995 by Coleman Research Corporation, under subcontract number 405810005-Y for Los Alamos National Laboratory (LANL). The study confirmed the issues identified in the Type C investigation, and also ascertained further issues or problems. During the course of this study two incidents involving hazardous waste resulted in the inappropriate disposal of the waste. An accidental spill, on June 8, 1995, at one of Laboratory buildings was not handled correctly, and ended up in the LAC Landfill. Hazardous waste was disposed of in a solid waste container and sent to the Los Alamos County Landfill. An attempt to locate the hazardous waste at the LAC Landfill was not successful. The second incident involving hazardous waste was discovered by the FSS-8, during a random dumpster surveillance. An interim dumpster program managed by FSS-8 discovered hazardous waste and copper chips in the solid waste, on August 9, 1995. The hazardous waste and copper chips would have been transported to the LAC Landfill if the audit team had not brought the problem to the awareness of the facility waste management personnel

  20. Morsleben waste acceptance requirements

    International Nuclear Information System (INIS)

    The Morsleben waste acceptance requirements take into account the valid stipulations in the permanent operational license of the Morsleben repository for radioactive waste (Eram) dated April 22, 1986, and in the documents underlying it. In line with the guaranteed continued validity until June 30, 2000 of this permanent operational license, also the classification of radioactive waste by waste types (A) and radiation protection groups (S) was retained. The revised requirements to be met by radioactive waste to be disposed of in Eram as issued by the German Federal Office for Radiation Protection (BfS) effective August 1996 constitute the safety framework which must be adhered to by this waste. They also take into account other stipulations by the BfS, especially voluntary restrictions and conditions imposed by the self-surveillance. Eram accepts the 'solid waste' and 'spent sealed radiation sources' categories. The waste generators must observe the requirements to be met by waste to be stored permanently. In the case of solid waste, these conditions include criteria to be met by waste forms, activity limitations for radionuclides and groups of radionuclides, and packaging criteria. (orig.)

    Disposal fees for mixed waste at proposed commercial disposal sites have been estimated to be $15,000 to $40,000 per cubit foot. If such high disposal fees are imposed, generators may be willing to apply extraordinary treatment or regulatory approaches to properly dispose of their mixed waste. This paper explores the feasibility of several waste management scenarios and attempts to answer the question: Can mixed waste be managed out of existence? Existing data on commercially generated mixed waste streams are used to identify the realm of mixed waste known to be generated. Each waste stream is evaluated from both a regulatory and technical perspective in order to convert the waste into a strictly low-level radioactive or a hazardous waste. Alternative regulatory approaches evaluated in this paper include a delisting petition, no migration petition, and a treatability variance. For each waste stream, potentially available treatment options are identified that could lead to these variances. Waste minimization methodology and storage for decay are also considered. Economic feasibility of each option is discussed broadly.

    According to the Section 24 of the Finnish Radiation Decree (1512/91), the Finnish Centre for Radiation and Nuclear Safety shall specify the concentration and activity limits and principles for the determination whether a waste can be defined as a radioactive waste or not. The radiation safety requirements and limits for the disposal of radioactive waste are given in the guide. They must be observed when discharging radioactive waste into the atmosphere or sewer system, or when delivering solid low-activity waste to a landfill site without a separate waste disposal plan. The guide does not apply to the radioactive waste resulting from the utilization of nuclear energy of natural resources. (4 refs., 1 tab.)

  4. Low level waste disposal

    International Nuclear Information System (INIS)

    Final disposal of low level wastes has been carried out for 15 years on the shallow land disposal of the Manche in the north west of France. Final participant in the nuclear energy cycle, ANDRA has set up a new waste management system from the production center (organization of the waste collection) to the disposal site including the setting up of a transport network, the development of assessment, additional conditioning, interim storage, the management of the disposal center, records of the location and characteristics of the disposed wastes, site selection surveys for future disposals and a public information Department. 80 000 waste packages representing a volume of 20 000 m3 are thus managed and disposed of each year on the shallow land disposal. The disposal of low level wastes is carried out according to their category and activity level: - in tumuli for very low level wastes, - in monoliths, a concrete structure, of the packaging does not provide enough protection against radioactivity

  5. Wastes in space

    International Nuclear Information System (INIS)

    As human space activities have created more wastes on low and high Earth orbits over the past 50 years than the solar system injected meteorites over billions of years, this report gives an overview of this problem. It identifies the origins of these space debris and wastes (launchers, combustion residues, exploitation wastes, out-of-use satellites, accidental explosions, accidental collisions, voluntary destructions, space erosion), and proposes a stock list of space wastes. Then, it distinguishes the situation for the different orbits: low Earth orbit or LEO (traffic, presence of the International Space Station), medium Earth orbits or MEO (traffic, operating satellites, wastes), geostationary Earth orbit or GEO (traffic, operating satellites, wastes). It also discusses wastes and bacteria present on the moon (due to Apollo missions or to crash tests). It evokes how space and nuclear industry is concerned, and discusses the re-entry issue (radioactive boomerang, metallic boomerang). It also indicates elements of international law

  6. Tank waste treatment science

    International Nuclear Information System (INIS)

    Remediation efforts at the U.S. Department of Energy's Hanford Site require that many technical and scientific principles be combined for effectively managing and disposing the variety of wastes currently stored in underground tanks. Based on these principles, pretreatment technologies are being studied and developed to separate waste components and enable the most suitable treatment methods to be selected for final disposal of these wastes. The Tank Waste Treatment Science Task at Pacific Northwest Laboratory is addressing pretreatment technology development by investigating several aspects related to understanding and processing the tank contents. The experimental work includes evaluating the chemical and physical properties of the alkaline wastes, modeling sludge dissolution, and evaluating and designing ion exchange materials. This paper gives some examples of results of this work and shows how these results fit into the overall Hanford waste remediation activities. This work is part of series of projects being conducted for the Tank Waste Remediation System

  7. Thermal plasma waste treatment

    International Nuclear Information System (INIS)

    Plasma waste treatment has over the past decade become a more prominent technology because of the increasing problems with waste disposal and because of the realization of opportunities to generate valuable co-products. Plasma vitrification of hazardous slags has been a commercial technology for several years, and volume reduction of hazardous wastes using plasma processes is increasingly being used. Plasma gasification of wastes with low negative values has attracted interest as a source of energy and spawned process developments for treatment of even municipal solid wastes. Numerous technologies and approaches exist for plasma treatment of wastes. This review summarizes the approaches that have been developed, presents some of the basic physical principles, provides details of some specific processes and considers the advantages and disadvantages of thermal plasmas in waste treatment applications.

    International Nuclear Information System (INIS)

    The authors give explanations and answers to ten issues related to nuclear wastes: when a radioactive material becomes a waste, how radioactive wastes are classified and particularly nuclear wastes in France, what are the risks associated with radioactive wastes, whether the present management of radioactive wastes is well controlled in France, which wastes are raising actual problems and what are the solutions, whether amounts and radio-toxicity of wastes can be reduced, whether all long life radionuclides or part of them can be transmuted, whether geologic storage of final wastes is inescapable, whether radioactive material can be warehoused over long durations, and how the information on radioactive waste management is organised

  10. Waste: energy to burn

    International Nuclear Information System (INIS)

    Incinerated, transformed into fuel or a gas, waste is a versatile source of energy. It is as once a problem and a resource that is increasingly the focus of green policies. According to the 2009 World Waste Survey, between 3.4 and 4 billion tons of waste are produced each year worldwide. Leading the pack is China, with 300 million tons produced in 2005, followed closely by the United States, with 238 million tons. But the United States wins the per capita count with 760 kg of waste produced per year per inhabitant; Australia comes in second. In Europe, 500 kg of waste is produced per capita per year for a total of 2 billion tons generated annually, and a growth rate of 10% in ten years' time. Between 2/3 and 3/4 of these waste materials are sorted, and a portion of them is recycled. The rest is either carted away to a dumping ground, or incinerated. But this waste is primarily domestic, and still contains energy, energy that can be recovered. The added bonus is two-fold: an additional source of energy is created by transforming waste, called waste-to- wheel or waste-to-energy (WTE), and the decomposition of organic waste does not give off GHGs. Two ways are known today to transform wastes into energy: the thermal process, where heat is extracted from the waste (and sometimes converted into electricity), and the non-thermal process, which comprises collecting energy in a chemical form (biogas, biofuel). Both technologies depend on the type of waste to be treated: plastic materials, household refuse, fermentable elements, sludge residue from sewage treatment plants, agricultural waste, forestry industry waste, etc. The thermal process is by far the most widely employed. 74% of waste is incinerated in Japan, and around 30 to 55% in most European countries. The second process does not burn waste and is better suited to wet and organic matter, i.e., to waste that contains quantities of biomass: fermentable waste, sludge, agricultural waste and the gas given off at

  13. Mixed Waste Management Facility

    International Nuclear Information System (INIS)

    The DOE has developed a National Mixed Waste Strategic Plan which calls for the construction of 2 to 9 mixed waste treatment centers in the Complex in the near future. LLNL is working to establish an integrated mixed waste technology development and demonstration system facility, the Mixed Waste Management Facility (MWMF), to support the DOE National Mixed Waste Strategic Plan. The MWMF will develop, demonstrate, test, and evaluate incinerator-alternatives which will comply with regulations governing the treatment and disposal of organic mixed wastes. LLNL will provide the DOE with engineering data for design and operation of new technologies which can be implemented in their mixed waste treatment centers. MWMF will operate under real production plant conditions and process samples of real LLNL mixed waste. In addition to the destruction of organic mixed wastes, the development and demonstration will include waste feed preparation, material transport systems, aqueous treatment, off-gas treatment, and final forms, thus making it an integrated ''cradle to grave'' demonstration. Technologies from offsite as well as LLNL's will be tested and evaluated when they are ready for a pilot scale demonstration, according to the needs of the DOE

    A final vitrified waste form composition, based upon the chemical compositions of the input waste streams, is recommended for the transuranic-contaminated waste stored at the Transuranic Storage Area of the Radioactive Waste Management Complex at the Idaho National Engineering Laboratory. The quantities of waste are large with a considerable uncertainty in the distribution of various waste materials. It is therefore impractical to mix the input waste streams into an ``average`` transuranic-contaminated waste. As a result, waste stream input to a melter could vary widely in composition, with the potential of affecting the composition and properties of the final waste form. This work examines the extent of the variation in the input waste streams, as well as the final waste form under conditions of adding different amounts of soil. Five prominent Rocky Flats Plant 740 waste streams are considered, as well as nonspecial metals and the ``average`` transuranic-contaminated waste streams. The metals waste stream is the most extreme variation and results indicate that if an average of approximately 60 wt% of the mixture is soil, the final waste form will be predominantly silica, alumina, alkaline earth oxides, and iron oxide. This composition will have consistent properties in the final waste form, including high leach resistance, irrespective of the variation in waste stream. For other waste streams, much less or no soil could be required to yield a leach resistant waste form but with varying properties.

    The waste types discussed in this Solid Waste Management Plan are Municipal Solid Waste, Hazardous Waste, Low-Level Mixed Waste, Low-Level Radioactive Waste, and Transuranic Waste. The plan describes for each type of solid waste, the existing waste management facilities, the issues, and the assumptions used to develop the current management plan.

  17. Waste statistics 2004

    2006-04-07

    The 2004 reporting to the ISAG comprises 394 plants owned by 256 enterprises. In 2003, reports covered 403 plants owned by 273 enterprises. Waste generation in 2004 is compared to targets for 2008 in the government's Waste Strategy 2005-2008. The following summarises waste generation in 2004: 1) In 2004, total reported waste arisings amounted to 13,359,000 tonnes, which is 745,000 tonnes, or 6 per cent, more than in 2003. 2) If amounts of residues from coal-fired power plants are excluded from statistics, waste arisings in 2004 were 12,179,000 tonnes, which is a 9 per cent increase from 2003. 3) If amounts of residues from coal-fired power plants and waste from the building and construction sector are excluded from statistics, total waste generation in 2004 amounted to 7,684,000 tonnes, which is 328,000 tonnes, or 4 per cent, more than in 2002. In other words, there has been an increase in total waste arisings, if residues and waste from building and construction are excluded. Waste from the building and construction sector is more sensitive to economic change than most other waste. 4) The total rate of recycling was 65 per cent. The 2008 target for recycling is 65 per cent. The rate of recycling in 2003 was also 65 per cent. 5) The total amount of waste led to incineration amounted to 26 per cent, plus an additional 1 per cent left in temporary storage to be incinerated at a later time. The 2008 target for incineration is 26 per cent. These are the same percentage figures as applied to incineration and storage in 2003. 6) The total amount of waste led to landfills amounted to 8 per cent, which is one percentage point better than the overall landfill target of a maximum of 9 per cent landfilling in 2008. Also in 2003, 8 per cent of the waste was landfilled. 7) The targets for treatment of waste from individual sectors are still not being met: too little waste from households and the service sector is being recycled, and too much waste from industry is being

  18. Waste acceptance and logistics

    International Nuclear Information System (INIS)

    There are three major components which are normally highlighted when the Civilian Radioactive Waste Management Program is discussed - the repository, the monitored retrievable storage facility, and the transportation system. These are clearly the major physical system elements and they receive the greatest external attention. However, there will not be a successful, operative waste management system without fully operational waste acceptance plans and logistics arrangements. This paper will discuss the importance of developing, on a parallel basis to the normally considered waste management system elements, the waste acceptance and logistics arrangements to enable the timely transfer of spent nuclear fuel from more than one hundred and twenty waste generators to the Federal government. The paper will also describe the specific activities the Program has underway to make the necessary arrangements. (author)

  19. Mixed waste regulation

    International Nuclear Information System (INIS)

    The Nuclear Regulatory Commission and the Environmental Protection Agency are developing a dual regulatory program governing mixed low-level radioactive and hazardous waste. Due to the absence of a facility authorized to accept such waste for disposal, mixed waste generators are forced to store such waste on-site and thereby subject themselves to complex technical standards and permitting requirements under the Resource Conservation and Recovery Act. The paper discusses the results to date of the nuclear utility industry's technical analyses on the mixed waste issue, describes the industry's proposals for a legislative resolution of the issue, and provides general guidance for development of a facility-specific regulatory strategy by individual mixed waste generators

  20. Radioactive waste management

    International Nuclear Information System (INIS)

    Throughout this century, the application of nuclear energy has produced many benefits, in industry, in research, in medicine, and in the generation of electricity. These activities generate wastes in the same way as do other human activities. The primary objective of radioactive waste management is to protect human health and environment now and in the future without imposing undue burden on future generations, through sound, safe and efficient radioactive waste management. This paper briefly describes the different steps of the management of short lived low and intermediate level wastes, and presents and overview of the state of art in countries involved in nuclear energy, describing their organizations, methodologies used in the processing of these wastes and the final disposal concepts. It also presents the Argentine strategy, its technical and legal aspects. Worldwide experience during the past 50 years has shown that short lived low and intermediate level wastes can be successfully isolated from human and environment in near surface disposal facilities.

    International Nuclear Information System (INIS)

    The main radioactive waste management issues to be faced by the Chilean Nuclear Energy Commission (CCHEN) are discussed herein. Research reactor spent fuel management is the most outstanding challenge at the beginning of the 21st century. Interim storage appears to be the most promising alternative, allowing fuel safekeeping until a definitive step is taken. The situation regarding radioactive waste resulting from radioisotope applications in Chile will not undergo considerable change in the near future. Low and intermediate level radioactive waste management is being safely performed followed by interim storage of conditioned wastes. The strategy in the radioactive waste management plan, to be described as well, is meant to ensure the safe storage of radioactive wastes produced in Chile. (author)

  2. Categorizing operational radioactive wastes

    International Nuclear Information System (INIS)

    The primary objective of this publication is to improve communications among waste management professionals and Member States relative to the properties and status of radioactive waste. This is accomplished by providing a standardized approach to operational waste categorization using accepted industry practices and experience. It is a secondary objective to draw a distinction between operational waste categorization and waste disposal classification. The approach set forth herein is applicable to waste generation by mature (major, advanced) nuclear programmes, small-to-medium sized nuclear programmes, and programmes with waste from other nuclear applications. It can be used for planning, developing or revising categorization methodologies. For existing categorization programmes, the approach set forth in this publication may be used as a validation and evaluation tool for assessing communication effectiveness among affected organizations or nations. This publication is intended for use by waste management professionals responsible for creating, implementing or communicating effective categorization, processing and disposal strategies. For the users of this publication, it is important to remember that waste categorization is a communication tool. As such, the operational waste categories are not suitable for regulatory purposes nor for use in health and safety evaluations. Following Section 1 (Introduction) Section 2 of this publication defines categorization and its relationship to existing waste classification and management standards, regulations and practices. It also describes the benefits of a comprehensive categorization programme and fundamental record considerations. Section 3 provides an overview of the categorization process, including primary categories and sub-categories. Sections 4 and 5 outline the specific methodology for categorizing unconditioned and conditioned wastes. Finally, Section 6 provides a brief summary of critical considerations that

    2008-01-01

    A comprehensive understanding of the quantities and characteristics of the material that needs to be managed is one of the most basic steps in the development of a plan for solid waste management. In this case, the material under consideration is the solid waste generated in healthcare facilities, also known as healthcare waste. Unfortunately, limited reliable information is available in the open literature on the quantities and characteristics of the various types of wastes that are generated in healthcare facilities. Thus, sound management of these wastes, particularly in developing countries, often is problematic. This article provides information on the quantities and properties of healthcare wastes in various types of facilities located in developing countries, as well as in some industrialized countries. Most of the information has been obtained from the open literature, although some information has been collected by the authors and from reports available to the authors. Only data collected within approximately the last 15 years and using prescribed methodologies are presented. The range of hospital waste generation (both infectious and mixed solid waste fractions) varies from 0.016 to 3.23kg/bed-day. The relatively wide variation is due to the fact that some of the facilities surveyed in Ulaanbaatar include out-patient services and district health clinics; these facilities essentially provide very basic services and thus the quantities of waste generated are relatively small. On the other hand, the reported amount of infectious (clinical, yellow bag) waste varied from 0.01 to 0.65kg/bed-day. The characteristics of the components of healthcare wastes, such as the bulk density and the calorific value, have substantial variability. This literature review and the associated attempt at a comparative analysis point to the need for worldwide consensus on the terms and characteristics that describe wastes from healthcare facilities. Such a consensus would greatly

  14. Avoidable waste management costs

    International Nuclear Information System (INIS)

    This report describes the activity based costing method used to acquire variable (volume dependent or avoidable) waste management cost data for routine operations at Department of Energy (DOE) facilities. Waste volumes from environmental restoration, facility stabilization activities, and legacy waste were specifically excluded from this effort. A core team consisting of Idaho National Engineering Laboratory, Los Alamos National Laboratory, Rocky Flats Environmental Technology Site, and Oak Ridge Reservation developed and piloted the methodology, which can be used to determine avoidable waste management costs. The method developed to gather information was based on activity based costing, which is a common industrial engineering technique. Sites submitted separate flow diagrams that showed the progression of work from activity to activity for each waste type or treatability group. Each activity on a flow diagram was described in a narrative, which detailed the scope of the activity. Labor and material costs based on a unit quantity of waste being processed were then summed to generate a total cost for that flow diagram. Cross-complex values were calculated by determining a weighted average for each waste type or treatability group based on the volume generated. This study will provide DOE and contractors with a better understanding of waste management processes and their associated costs. Other potential benefits include providing cost data for sites to perform consistent cost/benefit analysis of waste minimization and pollution prevention (WMIN/PP) options identified during pollution prevention opportunity assessments and providing a means for prioritizing and allocating limited resources for WMIN/PP

    2000-08-11

    The Building 772-F Far-Field Transuranic (TRU) Waste Counting System is used to measure the radionuclide content of waste packages produced at the Central Laboratory Facilities (CLAB). Data from the instrument are entered into one of two Excel spreadsheets. The waste stream associated with the waste package determines which spreadsheet is actually used. The spreadsheets calculate the necessary information required for completion of the Transuranic Waste Characterization Form (OSR 29-90) and the Radioactive Solid Waste Burial Ground Record (OSR 7-375 or OSR 7-375A). In addition, the spreadsheets calculate the associated Low Level Waste (LLW) stream information that potentially could be useful if the waste container is ever downgraded from TRU to LLW. The spreadsheets also have the capability to sum activities from source material added to a waste container after assay. A validation data set for each spreadsheet along with the appropriate results are also presented in this report for spreadsheet verification prior to each use.

  16. WASTE PACKAGE TRANSPORTER DESIGN

    International Nuclear Information System (INIS)

    The purpose of this Design Analysis is to develop preliminary design of the waste package transporter used for waste package (WP) transport and related functions in the subsurface repository. This analysis refines the conceptual design that was started in Phase I of the Viability Assessment. This analysis supports the development of a reliable emplacement concept and a retrieval concept for license application design. The scope of this analysis includes the following activities: (1) Assess features of the transporter design and evaluate alternative design solutions for mechanical components. (2) Develop mechanical equipment details for the transporter. (3) Prepare a preliminary structural evaluation for the transporter. (4) Identify and recommend the equipment design for waste package transport and related functions. (5) Investigate transport equipment interface tolerances. This analysis supports the development of the waste package transporter for the transport, emplacement, and retrieval of packaged radioactive waste forms in the subsurface repository. Once the waste containers are closed and accepted, the packaged radioactive waste forms are termed waste packages (WP). This terminology was finalized as this analysis neared completion; therefore, the term disposal container is used in several references (i.e., the System Description Document (SDD)) (Ref. 5.6). In this analysis and the applicable reference documents, the term ''disposal container'' is synonymous with ''waste package''

    The guideline of the Ministry for Environmental Protection for controlling radioactive waste with a negligible development of heat defines in detail what data are relevant to the control of radioactive waste and should be followed up on and included in a system of documentation. By introducing the AVK (product control system for tracing the course of waste disposal) the operators of German nuclear power plants have taken the requirements of this guideline into account. In particular, possibilities for determining the degree of radioactivity of radioactive waste, which the BMU-guidelines call for, were put into practice by means of the programming technology of the product control system's module MOPRO.

  1. Politics of nuclear waste

    International Nuclear Information System (INIS)

    In November of 1979, the Program in Science, Technology and Humanism and the Energy Committee of the Aspen Institute organized a conference on resolving the social, political, and institutional conflicts over the permanent siting of radioactive wastes. This book was written as a result of this conference. The chapters provide a comprehensive and up-to-date overview of the governance issues connected with radioactive waste management as well as a sampling of the diverse views of the interested parties. Chapter 1 looks in depth of radioactive waste management in the United States, with special emphasis on the events of the Carter Administration as well as on the issues with which the Reagen administration must deal. Chapter 2 compares waste management policies and programs among the industralized countries. Chapter 3 examines the factional controversies in the last administration and Congress over nuclear waste issues. Chapter 4 examines the complex legal questions involved in the federal-state conflicts over nuclear waste management. Chapter 5 examines the concept of consultation and concurrence from the perspectives of a host state that is a candidate for a repository and an interested state that has special concerns regarding the demonstration of nuclear waste disposal technology. Chapter 6 examines US and European perspectives concerning public participation in nuclear waste management. Chapter 7 discusses propaganda in the issues. The epilogue attempts to assess the prospects for consensus in the United States on national policies for radioactive waste management. All of the chapter in this book should be interpreted as personal assessments

    1995-10-01

    Waste Inspection Tomography (WIT) provides mobile semi-trailer mounted nondestructive examination (NDE) and assay (NDA) for nuclear waste drum characterization. WIT uses various computed tomography (CT) methods for both NDE and NDA of nuclear waste drums. Low level waste (LLW), transuranic (TRU), and mixed radioactive waste can be inspected and characterized without opening the drums. With externally transmitted x-ray NDE techniques, WIT has the ability to identify high density waste materials like heavy metals, define drum contents in two- and three-dimensional space, quantify free liquid volumes through density and x-ray attenuation coefficient discrimination, and measure drum wall thickness. With waste emitting gamma-ray NDA techniques, WIT can locate gamma emitting radioactive sources in two- and three-dimensional space, identify gamma emitting, isotopic species, identify the external activity levels of emitting gamma-ray sources, correct for waste matrix attenuation, provide internal activity approximations, and provide the data needed for waste classification as LLW or TRU.

    International Nuclear Information System (INIS)

    The appropriate managing of hazardous wastes is a problem little dealed in the wastes management in the country. A search of available information was made about the generation and handling to internal and external level of the hazardous wastes by national industries. It was worked with eleven companies of different types of industrial activities for, by means of a questionnaire, interviews and visits, to determine the degree of integral and suitable handling of the wastes that they generate. It was concluded that exist only some isolated reports on the generation of hazardous industrial wastes and handling. The total quantity of wastes generated in the country was impossible to establish. The companies consulted were deficient in all stages of the handling of their wastes: generation, accumulation and storage, transport, treatment and final disposition. The lack of knowledge of the legislation and of the appropriate managing of the wastes is showed as the principal cause of the poor management of the residues. The lack of state or private entities entrusted to give services of storage, transport, treatment and final disposition of hazardous wastes in the country was evident. (author)

    The landscape of electronic waste, e-waste, management is changing dramatically. Besides a rapidly increasing world population, globalization is driving the demand for products, resulting in rising prices for many materials. Absolute scarcity looms for some special resources such as indium. Used electronic products and recyclable materials are increasingly crisscrossing the globe. This is creating both - opportunities and challenges for e-waste management. This focuses on the current and future trends, technologies and regulations for reusable and recyclable e-waste worldwide.

  7. Waste minimization assessment procedure

    International Nuclear Information System (INIS)

    Perry Nuclear Power Plant began developing a waste minimization plan early in 1991. In March of 1991 the plan was documented following a similar format to that described in the EPA Waste Minimization Opportunity Assessment Manual. Initial implementation involved obtaining management's commitment to support a waste minimization effort. The primary assessment goal was to identify all hazardous waste streams and to evaluate those streams for minimization opportunities. As implementation of the plan proceeded, non-hazardous waste streams routinely generated in large volumes were also evaluated for minimization opportunities. The next step included collection of process and facility data which would be useful in helping the facility accomplish its assessment goals. This paper describes the resources that were used and which were most valuable in identifying both the hazardous and non-hazardous waste streams that existed on site. For each material identified as a waste stream, additional information regarding the materials use, manufacturer, EPA hazardous waste number and DOT hazard class was also gathered. Once waste streams were evaluated for potential source reduction, recycling, re-use, re-sale, or burning for heat recovery, with disposal as the last viable alternative

  8. Secondary Waste Cast Stone Waste Form Qualification Testing Plan

    Westsik, Joseph H.; Serne, R. Jeffrey

    2012-09-26

    The Hanford Tank Waste Treatment and Immobilization Plant (WTP) is being constructed to treat the 56 million gallons of radioactive waste stored in 177 underground tanks at the Hanford Site. The WTP includes a pretreatment facility to separate the wastes into high-level waste (HLW) and low-activity waste (LAW) fractions for vitrification and disposal. The LAW will be converted to glass for final disposal at the Integrated Disposal Facility (IDF). Cast Stone – a cementitious waste form, has been selected for solidification of this secondary waste stream after treatment in the ETF. The secondary-waste Cast Stone waste form must be acceptable for disposal in the IDF. This secondary waste Cast Stone waste form qualification testing plan outlines the testing of the waste form and immobilization process to demonstrate that the Cast Stone waste form can comply with the disposal requirements. Specifications for the secondary-waste Cast Stone waste form have not been established. For this testing plan, Cast Stone specifications are derived from specifications for the immobilized LAW glass in the WTP contract, the waste acceptance criteria for the IDF, and the waste acceptance criteria in the IDF Permit issued by the State of Washington. This testing plan outlines the testing needed to demonstrate that the waste form can comply with these waste form specifications and acceptance criteria. The testing program must also demonstrate that the immobilization process can be controlled to consistently provide an acceptable waste form product. This testing plan also outlines the testing needed to provide the technical basis for understanding the long-term performance of the waste form in the disposal environment. These waste form performance data are needed to support performance assessment analyses of the long-term environmental impact of the secondary-waste Cast Stone waste form in the IDF

  9. Waste to wealth

    International Nuclear Information System (INIS)

    We currently live in a world where depletion of resources is beyond control. The call for sustainable development both environmentally and economically is spelt out loud and clear. Hence, the current and future generations must ensure that all resources shall be preserved, fully utilized and well managed. Waste generation has been part and parcel of man kinds pursuit for development, be it in social or economic activities. Municipal Solid Waste (MSW) is an example of socio-economic activities that entails with waste generation. Generation rates of MSW vary according to the economic and social standing of a country. This in return will also affect the management style of the MSW generated. Generally, the higher income countries generated more waste, recycle more and have the money to employ new technology to treat their waste. As for the lower income countries, the waste generated is more organic in nature, which calls for lesser recycling, whereas disposal is by open dumping. The effects of this naturally would mean that in the lower income countries pollution to the water and air is huge as compare to the more developed countries. However on the other hand, does waste alone generate harmful gasses that pollute the world or does manufacturing, transportation and power production, which is rampant in the more industrialized countries contributing more towards pollution? This subject is argumentative and could be discussed at length. However, the environment cannot wait for the population to debate on the above matter. Action needs to be taken in a world where economic power determines the treatment method. Hence, the idea of recovering all 'wealth' in the waste is essential to ensure that even the poorest countries could benefit from all waste management technologies. For this to work, recycling, reuse and recovery of energy is essential in an integrated approach towards waste management. This would also mean that many environmental disasters could be avoided

  10. Defense waste management plan

    International Nuclear Information System (INIS)

    Defense high-level waste (HLW) and defense transuranic (TRU) waste are in interim storage at three sites, namely: at the Savannah River Plant, in South Carolina; at the Hanford Reservation, in Washington; and at the Idaho National Engineering Laboratory, in Idaho. Defense TRU waste is also in interim storage at the Oak Ridge National Laboratory, in Tennessee; at the Los Alamos National Laboratory, in New Mexico; and at the Nevada Test Site, in Nevada. (Figure E-2). This document describes a workable approach for the permanent disposal of high-level and transuranic waste from atomic energy defense activities. The plan does not address the disposal of suspect waste which has been conservatively considered to be high-level or transuranic waste but which can be shown to be low-level waste. This material will be processed and disposed of in accordance with low-level waste practices. The primary goal of this program is to utilize or dispose of high-level and transuranic waste routinely, safely, and effectively. This goal will include the disposal of the backlog of stored defense waste. A Reference Plan for each of the sites describes the sequence of steps leading to permanent disposal. No technological breakthroughs are required to implement the reference plan. Not all final decisions concerning the activities described in this document have been made. These decisions will depend on: completion of the National Environmental Policy Act process, authorization and appropriation of funds, agreements with states as appropriate, and in some cases, the results of pilot plant experiments and operational experience. The major elements of the reference plan for permanent disposal of defense high-level and transuranic waste are summarized

  14. Radioactive waste storage issues

    International Nuclear Information System (INIS)

    In the United States we generate greater than 500 million tons of toxic waste per year which pose a threat to human health and the environment. Some of the most toxic of these wastes are those that are radioactively contaminated. This thesis explores the need for permanent disposal facilities to isolate radioactive waste materials that are being stored temporarily, and therefore potentially unsafely, at generating facilities. Because of current controversies involving the interstate transfer of toxic waste, more states are restricting the flow of wastes into - their borders with the resultant outcome of requiring the management (storage and disposal) of wastes generated solely within a state's boundary to remain there. The purpose of this project is to study nuclear waste storage issues and public perceptions of this important matter. Temporary storage at generating facilities is a cause for safety concerns and underscores, the need for the opening of permanent disposal sites. Political controversies and public concern are forcing states to look within their own borders to find solutions to this difficult problem. Permanent disposal or retrievable storage for radioactive waste may become a necessity in the near future in Colorado. Suitable areas that could support - a nuclear storage/disposal site need to be explored to make certain the health, safety and environment of our citizens now, and that of future generations, will be protected

    Reports to the ISAG (Information System for Waste and Recycling) for 2001 cover 402 Danish waste treatment plants owned by 295 enterprises. The total waste generation in 2001 amounted to 12,768,000 tonnes, which is 2% less than in 2000. Reductions are primarily due to the fact that sludge for mineralization is included with a dry matter content of 20% compared to 1,5% in previous statistics. This means that sludge amounts have been reduced by 808,886 tonnes. The overall rate of recycling amounted to 63%, which is 1% less than the overall recycling target of 64% for 2004. Since sludge has a high recycling rate, the reduction in sludge amounts of 808,886 tonnes has also caused the total recycling rate to fall. Waste amounts incinerated accounted for 25%, which is 1% more than the overall target of 24% for incineration in 2004. Waste going to landfill amounted to 10%, which is better than the overall landfill target for 2004 of a maximum of 12% for landfilling. Targets for treatment of waste from the different sectors, however, are still not complied with, since too little waste from households and the service sector is recycled, and too much waste from industry is led to landfill.

    Litwiller, Eric; Flynn, Michael; Fisher, John; Reinhard, Martin

    2004-01-01

    This paper discusses the development of a solid waste treatment system that has been designed for a Mars transit exploration mission. The technology described is an energy-efficient lyophilization technique that is designed to recover water from spacecraft solid wastes. Candidate wastes include feces, concentrated brines from water processors, and other solid wastes that contain free water. The system is designed to operate as a stand-alone process or to be integrated into the International Space Station Waste Collection System. In the lyophilization process, water in an aqueous waste is frozen and then sublimed, separating the waste into a dried solid material and liquid water. The sublimed water is then condensed in a solid ice phase and then melted to generate a liquid product. In the subject system the waste solids are contained within a 0.2 micron bio-guard bag and after drying are removed from the system and stored in a secondary container. This technology is ideally suited to applications such as the Mars Reference Mission, where water recovery rates approaching 100% are desirable but production of CO2 is not. The system is designed to minimize power consumption through the use of thermoelectric heat pumps. The results of preliminary testing of a prototype system and testing of the final configuration are provided. A mathematical model of the system is also described.

    Full Text Available Waste management in foundries is gaining a higher ecological and economical importance. Waste is becoming an increasingly traded product, where excellent profits can be made. Due to the cost reduction and successful business operation in companies, waste has to be regenerated and used again as a material to the maximum possible extent. Such research is long lasting and expensive and is a great challenge for companies. In the frame of our research, a total waste management case study for the Slovenian foundry Feniks was carried out. From the sustainable development point of view, waste management is most suitable, since it ensures the material utilization of waste, reduces the consumption of natural renewable or non-renewable resources and makes efficient production capacity utilization possible. Properly treated ecologically safe waste with a suitable physical characteristic, long-term existence, is a substitute for natural materials. Sand, dust, slag and other mineral waste from foundries are increasingly being used as materials in other industries. The foundry Feniks was awarded with certification of the environmental management system according to the standard SIST EN ISO 14001 and confirmed its environmental credentials.

  5. Waste management in Brazil

    International Nuclear Information System (INIS)

    The waste management policies set up in developed countries have in general been used by other countries with less experience in the nuclear field as the basis for developing waste disposal rules or guidelines according to their particular political, social and economic conditions. The waste management question became a main concern in Brazil during the licensing period of the Angra I nuclear power plant and the other fuel cycle facilities envisaged under the Agreement between Brazil and the Federal Republic of Germany. Before the Angra I licensing period, all final waste products arising from nuclear activities were released into the environment because their radioactive levels were below the standard limits. The Research, Development and Demonstration (RDD) Project initiated by the National Nuclear Energy Commission has the purpose to provide information that may contribute to the formulation of recommendations for a waste disposal policy, as well as to demonstrate the feasibility of the Brazilian waste disposal concept. The paper briefly describes the waste management policy in some countries, their contributions to the studies carried out in the RDD Project, and the recommendations and mechanisms for implementing the waste management proposal, and presents general information concerning the Brazilian repository concept.

    The Savannah River Site (SRS) is a Department of Energy (DOE) facility encompassing approximately 800 square kilometers near Aiken, South Carolina which began operations in the 1950's with the mission to produce nuclear materials. The SRS contains fifty-one tanks (2 stabilized, 49 yet to be closed) distributed between two liquid radioactive waste storage facilities at SRS containing carbon steel underground tanks with storage capacities ranging from 2,800,000 to 4,900,000 liters. Treatment of the liquid waste from these tanks is essential both to closing older tanks and to maintaining space needed to treat the waste that is eventually vitrified or disposed of onsite. Section 3116 of the Ronald W. Reagan National Defense Authorization Act of Fiscal Year 2005 (NDAA) provides the Secretary of Energy, in consultation with the Nuclear Regulatory Commission (NRC), a methodology to determine that certain waste resulting from prior reprocessing of spent nuclear fuel are not high-level radioactive waste if it can be demonstrated that the waste meets the criteria set forth in Section 3116(a) of the NDAA. The Secretary of Energy, in consultation with the NRC, signed a determination in January 2006, pursuant to Section 3116(a) of the NDAA, for salt waste disposal at the SRS Saltstone Disposal Facility. This determination is based, in part, on the Basis for Section 3116 Determination for Salt Waste Disposal at the Savannah River Site and supporting references, a document that describes the planned methods of liquid waste treatment and the resulting waste streams. The document provides descriptions of the proposed methods for processing salt waste, dividing them into 'Interim Salt Processing' and later processing through the Salt Waste Processing Facility (SWPF). Interim Salt Processing is separated into Deliquification, Dissolution, and Adjustment (DDA) and Actinide Removal Process/Caustic Side Solvent Extraction Unit (ARP/MCU).

    The 2003 reporting to the ISAG comprises 403 plants owned by 273 enterprises. In 2002, reports covered 407 plants owned by 296 enterprises. Waste generation in 2003 is compared to targets from 2008 in the government's Waste Strategy 2005-2008. The following can be said to summarise waste generation in 2003: 1) In 2003, total reported waste arisings amounted to 12,835,000 tonnes, which is 270,000 tonnes, or 2 per cent, less than in 2002. 2) If amounts of residues from coal-fired power plants are excluded from statistics, waste arisings in 2003 were 11,597,000 tonnes, which is a 2 per cent increase from 2002. 3) If amounts of residues from coal-fired power plants and waste from the building and construction sector are excluded from statistics, total waste generation in 2003 amounted to 7,814,000 tonnes, which is 19,000 tonnes, or 1 per cent, less than in 2002. In other words, there has been a fall in total waste arisings, if residues and waste from building and construction are excluded. 4) The overall rate of recycling amounted to 66 per cent, which is one percentage point above the overall recycling target of 65 per cent for 2008. In 2002 the total rate of recycling was 64 per cent. 5) The total amount of waste led to incineration amounted to 26 per cent, plus an additional 1 per cent left in temporary storage to be incinerated at a later time. The 2008 target for incineration is 26 per cent. These are the same percentage figures as applied to incineration and storage in 2002. 6) The total amount of waste led to landfills amounted to 8 per cent, which is one percentage point below the overall landfill target of a maximum of 9 per cent landfilling in 2008. In 2002, 9 per cent was led to landfill. 7) The targets for treatment of waste from individual sectors are still not being met: too little waste from households and the service sector is being recycled, and too much waste from industry is being led to landfill.

    International Nuclear Information System (INIS)

    Vitrification of wastes is a relatively new application of none of man's oldest manufacturing processes. During the past 25 years it has been developed and accepted internationally for immobilizing the most highly radioactive wastes from spent nuclear fuel. By the year 2005, there will be nine operating high-level radioactive vitrification plants. Many of the technical ''lessons learned'' from this international program can be applied to much less hazardous materials such as naturally occurring radioactive material (NORM). With the deployment of low capital and operating cost systems, vitrification should become a broadly applied process for treating a large variety of wastes. In many situations, the wastes can be transformed into marketable products. This paper will present a general description of waste vitrification, summarize some of its key advantages, provide some test data for a small sample of one NORM, and suggest how this process may be applied to NORM

  15. Classification of radioactive waste

    International Nuclear Information System (INIS)

    Radioactive wastes are generated in a number of different kinds of facilities and arise in a wide range of concentrations of radioactive materials and in a variety of physical and chemical forms. To simplify their management, a number of schemes have evolved for classifying radioactive waste according to the physical, chemical and radiological properties of significance to those facilities managing this waste. These schemes have led to a variety of terminologies, differing from country to country and even between facilities in the same country. This situation makes it difficult for those concerned to communicate with one another regarding waste management practices. This document revises and updates earlier IAEA references on radioactive waste classification systems given in IAEA Technical Reports Series and Safety Series. Guidance regarding exemption of materials from regulatory control is consistent with IAEA Safety Series and the RADWASS documents published under IAEA Safety Series. 11 refs, 2 figs, 2 tab

  16. Verifying generator waste certification: NTS waste characterization QA requirements

    International Nuclear Information System (INIS)

    Waste management activities managed by the US Department of Energy (DOE) at the Nevada Test Site (NTS) include the disposal of low-level wastes (LLW) and mixed waste (MW), waste which is both radioactive and hazardous. A majority of the packaged LLW is received from offsite DOE generators. Interim status for receipt of MW at the NTS Area 5 Radioactive Waste Management Site (RWMS) was received from the state of Nevada in 1987. The RWMS Mixed Waste Management Facility (MWMF) is expected to be operational in 1988 for approved DOE MW generators. The Nevada Test Site Defense Waste Acceptance Criteria and Certification Requirements (NVO-185, Revision 5) delineates waste acceptance criteria for waste disposal at the NTS. Regulation of the hazardous component of mixed waste requires the implementation of US Environmental Protection Agency (EPA) requirements pursuant to the Resource Conservation and Recovery Act (RCRA). Waste generators must implement a waste certification program to provide assurance that the disposal site waste acceptance criteria are met. The DOE/Nevada Operations Office (NV) developed guidance for generator waste certification program plans. Periodic technical audits are conducted by DOE/NV to assess performance of the waste certification programs. The audit scope is patterned from the waste certification program plan guidance as it integrates and provides a common format for the applicable criteria. The criteria focus on items and activities critical to processing, characterizing, packaging, certifying, and shipping waste

    International Nuclear Information System (INIS)

    All Member States have to a large or small extent nuclear activities that generate radioactive wastes. Hospitals, research in biomedicine or in agriculture, and some industrial applications, beside other large nuclear activities such as Nuclear Power Plants and Nuclear Research, generate unconditioned liquid or solid radioactive wastes that have to be treated, conditioned and stored prior final disposal. Countries with small nuclear activities require of organizations and infrastructure as to be able to manage, in a safe manner, the wastes that they generate. Predisposal management of radioactive waste is any step carried out to convert raw waste into a stable form suitable for the safe disposal, such as pre-treatment, treatment, storage and relevant transport. Transport of radioactive waste do not differ, in general, from other radioactive material and so are not considered within the scope of this fact sheet (Nevertheless the Agency, within the Nuclear Safety Department, has created a special Unit that might give advise Member States in this area). Predisposal management is comprised of a set of activities whose implementation may take some time. In most of the cases, safety issues and strategic and economical considerations have to be solved prior the main decisions are taken. The International Atomic Energy Agency provides assistance for the management of radioactive waste at national and operating level, in the definition and/or implementation of the projects. The services could include, but are not limited to guidance in the definition of national waste management strategy and its implementation, definition of the most adequate equipment and practices taking into account specific Member State conditions, as well as assisting in the procurement, technical expertise for the evaluation of current status of operating facilities and practical guidance for the implementation of corrective actions, assistance in the definition of waste acceptance criteria for

    Full Text Available The use of food waste recycling concept can be an interesting option to reduce the use of landfill. This strategy is more environmental friendly, cheap and fast if proper management to treat the food waste is applied. Nowadays, the concept of recycling is not well practice among the community. In this study, vermicomposting is introduced as an alternative of the food waste recycling. Vermicomposting consists of the use of earthworms to break down the food waste. In this vermicomposting treatment, the nightcrawler earthworm are used to treat the food waste. The food will be collected from UTHM cafe. The experiment consist of peat soil as a base, earthworms and the food waste. The pH number and moisture content of each container were controlled at 7.0 to 7.2 and 60 to 80 % to maintain the favorable environment condition for the earthworms. The weight of the sample will be measured in three days time after exposure to the earthworm. The vermicomposting study was taken about two weeks time. After the treatment, the soil sample are tested for nitrogen (N, Phosphorus (P, and Potassium (K concentration. Based on the result obtained, it shows that vermicomposting will reduce the weight of treatment sample and the concentration of N, P, and K for the soil is greater than the chemical fertilizer. Therefore, vermicomposting is a promising  alternative treatment of food waste as it is more ecofriendly.

  2. Buried Waste Integrated Demonstration

    International Nuclear Information System (INIS)

    The Buried Waste Integrated Demonstration (BWID) supports the applied research, development, demonstration, and evaluation of a suite of advanced technologies that offer promising solutions to the problems associated with the remediation of buried waste. BWID addresses the difficult remediation problems associated with DOE complex-wide buried waste, particularly transuranic (TRU) contaminated buried waste. BWID has implemented a systems approach to the development and demonstration of technologies that will characterize, retrieve, treat, and dispose of DOE buried wastes. This approach encompasses the entire remediation process from characterization to post-monitoring. The development and demonstration of the technology is predicated on how a technology fits into the total remediation process. To address all of these technological issues, BWID has enlisted scientific expertise of individuals and groups from within the DOE Complex, as well as experts from universities and private industry. The BWID mission is to support development and demonstration of a suite of technologies that, when integrated with commercially-available technologies, forms a comprehensive, remediation system for the effective and efficient remediation of buried waste throughout the DOE Complex. BWID will evaluate and validate demonstrated technologies and transfer this information and equipment to private industry to support the Office of Environmental Restoration (ER), Office of Waste Management (WM), and Office of Facility Transition (FT) remediation planning and implementation activities

  3. Waste inspection tomography (WIT)

    International Nuclear Information System (INIS)

    The WIT program will provide an inspection system that offers the nuclear waste evaluator a unique combination of tools for regulatory-driven characterization of low-level waste (LLW), transuranic waste (TRU), and mixed waste drums. WIT provides nondestructive, noninvasive, and environmentally safe inspections using X-ray and gamma ray technologies, with reasonable cost and throughput. Two emission imaging techniques will be employed for characterizing materials in waste containers. The first of these is gamma emission tomography, commonly called single-photon emission computed tomography (SPECT). Rather than using an external radiation source, SPECT uses the emission of radioactive materials within the object of interest for imaging. In this case, emission from actual nuclear waste within a container will provide a three-dimensional image of the radioactive substances in the container. The second emission technique will use high-purity germanium detectors for gamma ray spectroscopy. This technique, called nondestructive assay (NDA), can identify the emitting isotopic species and strength. Work in emission tomography and assay of nuclear waste has been undertaken at Lawrence Livermore National Laboratory using a technique called Passive Tomography. Results from a process development unit are presented

  4. Energy from waste

    International Nuclear Information System (INIS)

    In accordance with the fast growing population, the demand for energy and the discharge of waste are also increasing day by day. So, there is two method of waste treatment that practiced by our company, centralised and de centralised. For de centralised treatment, there are some advantages like no collection, no transportation, small investment and for disadvantages, more treatment plants are needed. Waste of food materials and other bio degradable wastes generated in Factory canteens, Convents, Hospitals, Hostels, Hotels and other industrial organizations can be treated in an eco-friendly way for the production of cooking gas in very large scale. BIOTECH has completed the installation of 52 Nos. power generation projects using market /slaughter house waste. The power generated from these projects is being utilized for energy requirements of the concerned markets and to meet the in-house requirements of the projects. In recognition of our selfless services to the society through our system of waste management and the generation of Energy from waste. BIOTECH was honored by conferring on it the prestigious International Ashden Award GREEN OSCAR 2007. (Author)

  5. Radioactive waste management profiles

    International Nuclear Information System (INIS)

    In 1989, the International Atomic Energy Agency began development of the Waste Management Data Base (WMDB) to, primarily, establish a mechanism for the collection, integration, storage, and retrieval of information relevant to radioactive waste management in Member States. This report is a summary and compilation of the information contained in the data base. The WMDB contains information and data on several aspects of waste management and offer a ready source of information on such activities as R and D efforts, waste disposal plans and programmes, important programme milestones, waste volume projections, and national and regulatory policies. This report is divided into two parts. Part one describes the Waste Management Data Base system and the type of information it contains. The second part contains data provided by Member States between August 1989 and December 1990 in response to a questionnaire sent by the Agency. However, if a Member State did not respond to the questionnaire, data from IAEA sources, such as technical assistance mission reports, were used - where such data exist. The WMDB system became operational in January 1991. The type of information contained in the data base includes radioactive waste management plans, policies and activities in Member States

  6. Canberra waste assay systems

    International Nuclear Information System (INIS)

    Canberra Industries, Inc. (USA) offers complete solutions and turnkey systems for qualifying and quantifying drums of radioactive waste. Different Waste Assay Systems are available for low-, medium-, and high activity barrels. Such systems scan the segments of the drums. The gamma-emitting nuclides present in the radioactive waste are identified from the spectra of the gamma-rays emitted and their activities are quantified. The spectrum of each segment of the waste container is analysed separately and the results are summed for total drum inventory reporting. The Waste Assay specific Canberra software is an easy-to-use menu driven program. It offers automatic procedures for routine work but interactive mode is also available to investigate particular cases. The way of analysis and the format and contents of the report can be customized. Additional Quality Control program module monitors system parameters. The measured and calculated values of each waste container are saved into a relational database. Canberra offers mathematical efficiency calibration services for different drum types, with different waste densities and different activities. This new theoretical approach of efficiency calibration eliminates the need of calibration drums, thus saving costs. For field applications Canberra developed a portable In-Situ Object Counting System. This system determines efficiency calibration for any kind of objects after the user enters its size and density, furthermore the type of shielding and the distance between the detector and the object.

  7. Solid Waste Program Plan

    International Nuclear Information System (INIS)

    The objective of the Solid Waste Program Plan (SWPP) is to provide a summary level comprehensive approach for the storage, treatment, and disposal of current and future solid waste received at the Hanford Site (from onsite and offsite generators) in a manner compliant with current and evolving applicable regulations and orders [federal, state, local, and Westinghouse Hanford Company (Westinghouse Hanford)]. A previous version of the SWPP (entitled Solid Waste Management Program Plan) was drafted in 1990 and released as WHC-EP-0363 (WHC 1990c). The SWPP also presents activities required for disposal of selected wastes currently in retrievable storage. The SWPP provides a central focus for the description and control of cost, scope, and schedule of Hanford Site solid waste activities and provides a vehicle for ready communication of the scope of these activities to onsite and offsite organizations. This SWPP represents the most complete description available of Hanford Site solid waste activities and the interfaces between those activities. It will be updated annually to reflect changes in plans due to evolving regulatory requirements and/or the solid waste mission. 26 refs., 11 figs., 1 tabs

  8. Compactable reactor waste characterization

    International Nuclear Information System (INIS)

    Compactable reactor wastes were characterized in respect of physical composition. β/γ activity levels, radionuclide inventory, and tritium and carbon-14 content. 1072 bags of waste representing 18 bales with a volume of 9 m3 were examined. This waste is extremely heterogeneous and can contain any item or material used at nuclear generating stations. The β/γ activity level of the waste is low; at the time of manufacture the 18 bales ranged between 1.0 and 6.94 mCi most of which was attributable to radionuclides with a half-life of one year or less. After ten years' decay the activity of any bale will have decreased to a maximum of 1.5 mCi and the only β/γ radionuclides of significance will be 60Co and 137Cs. Tritium and carbon-14 were found in most of the waste bags and it is estimated that a cubic metre of waste could contain 8.4 to 11.3 Ci of tritium and 0.8 to 5.4 μCi carbon-14. It is considered there is no need for further conditioning of this waste for disposal

  9. TRU Waste Sampling Program: Volume I. Waste characterization

    International Nuclear Information System (INIS)

    Volume I of the TRU Waste Sampling Program report presents the waste characterization information obtained from sampling and characterizing various aged transuranic waste retrieved from storage at the Idaho National Engineering Laboratory and the Los Alamos National Laboratory. The data contained in this report include the results of gas sampling and gas generation, radiographic examinations, waste visual examination results, and waste compliance with the Waste Isolation Pilot Plant-Waste Acceptance Criteria (WIPP-WAC). A separate report, Volume II, contains data from the gas generation studies

  10. Comparative waste forms study

    International Nuclear Information System (INIS)

    A number of alternative process and waste form options exist for the immobilization of nuclear wastes. Although data exists on the characterization of these alternative waste forms, a straightforward comparison of product properties is difficult, due to the lack of standardized testing procedures. The characterization study described in this report involved the application of the same volatility, mechanical strength and leach tests to ten alternative waste forms, to assess product durability. Bulk property, phase analysis and microstructural examination of the simulated products, whose waste loading varied from 5% to 100% was also conducted. The specific waste forms investigated were as follows: Cold Pressed and Sintered PW-9 Calcine; Hot Pressed PW-9 Calcine; Hot Isostatic Pressed PW-9 Calcine; Cold Pressed and Sintered SPC-5B Supercalcine; Hot Isostatic pressed SPC-5B Supercalcine; Sintered PW-9 and 50% Glass Frit; Glass 76-68; Celsian Glass Ceramic; Type II Portland Cement and 10% PW-9 Calcine; and Type II Portland Cement and 10% SPC-5B Supercalcine. Bulk property data were used to calculate and compare the relative quantities of waste form volume produced at a spent fuel processing rate of 5 metric ton uranium/day. This quantity ranged from 3173 L/day (5280 Kg/day) for 10% SPC-5B supercalcine in cement to 83 L/day (294 Kg/day) for 100% calcine. Mechanical strength, volatility, and leach resistance tests provide data related to waste form durability. Glass, glass-ceramic and supercalcine ranked high in waste form durability where as the 100% PW-9 calcine ranked low. All other materials ranked between these two groupings

  11. Waste safety activities

    International Nuclear Information System (INIS)

    Safety standards develop by the IAEA in the Safety Standard Series and other publication are reviewed. The Waste Safety Action plan includes: Action 1: Develop a common framework for the management and disposal of different types of radioactive waste, paying particular attention to large volumes of waste containing long-lived naturally occurring radionuclides. Action 2: Assess the safety implications of the extended storage of radioactive waste and of any future reconditioning which may be necessary and develop safety standards for the long-term storage of radioactive waste. Action 3: Promptly develop safety standards for geological disposal, addressing inter alia, issues of human intrusion, institutional control, retrievability, the content of the safety case and any implications of nuclear safeguards requirements for the design of the repositories. Action 4: Develop an internationally accepted and harmonized approach for controlling the removal of materials and sites from regulatory control. Action 5: Develop a structured and systematic programme to ensure adequate application of the Agency waste safety standards and facilitate their application in implementation of the Joint Convention. Action 6: Explore ways to ensure that information, knowledge and skills concerning radioactive waste management are made available to future generations. Action 7: Address the broader societal dimensions of radioactive waste management. Action 8: Review the new developments related to policies for the control of radioactive discharges to the environment, taking into account the availability and cost-effectiveness of discharge reduction technologies and the broader implications for radioactive waste management of reducing discharges. Action 9: Explore international mechanisms for facilitating the management of spent sealed radioactive sources. Some other activities as training courses and technical cooperation are also presented

  12. Listed waste determination report

    International Nuclear Information System (INIS)

    On September 23, 1988, the US Environmental Protection Agency (EPA) published a notice clarifying interim status requirements for the management of radioactive mixed waste thereby subjecting the Idaho National Engineering Laboratory (INEL) and other applicable Department of Energy (DOE) sites to regulation under the Resource Conservation and Recovery Act (RCRA). Therefore, the DOE was required to submit a Part A Permit application for each treatment, storage, and disposal (TSD) unit within the INEL, defining the waste codes and processes to be regulated under RCRA. The September 1990 revised Part A Permit application, that was approved by the State of Idaho identified 101 potential acute and toxic hazardous waste codes (F-, P-, and U- listed wastes according to 40 CFR 261.31 and 40 CFR 261.33) for some TSD units at the Idaho Chemical Processing Plant. Most of these waste were assumed to have been introduced into the High-level Liquid Waste TSD units via laboratory drains connected to the Process Equipment Waste (PEW) evaporator (PEW system). At that time, a detailed and systematic evaluation of hazardous chemical use and disposal practices had not been conducted to determine if F-, P-, or Unlisted waste had been disposed to the PEW system. The purpose of this investigation was to perform a systematic and detailed evaluation of the use and disposal of the 101 F-, P-, and Unlisted chemicals found in the approved September 1990 Part A Permit application. This investigation was aimed at determining which listed wastes, as defined in 40 CFR 261.31 (F-listed) and 261.33 (P ampersand Unlisted) were discharged to the PEW system. Results of this investigation will be used to support revisions to the RCRA Part A Permit application

  13. Radioactive waste management

    International Nuclear Information System (INIS)

    This book highlights the main issues of public concern related to radioactive waste management and puts them into perspective. It provides an overview of radioactive waste management covering, among other themes, policies, implementation and public communication based on national experiences. Its purpose is to assists in increasing the understanding of radioactive waste management issues by public and national authorities, organizations involved in radioactive waste management and the nuclear industry; it may also serve as a source book for those who communicate with the public. Even in the unlikely event that nuclear power does not further develop around the world, the necessity for dealing with nuclear waste from past usages, from uranium mining and milling, decontamination and decommissioning of existing nuclear facilities and from the uses of radioactive materials in medicine, industry and research would still exist. In many countries, radioactive waste management planning involves making effective institutional arrangements in which responsibilities and liabilities are well established for the technical operation and long term surveillance of disposal systems. Financing mechanisms are part of the arrangements. Continuous quality assurance and quality control, at all levels of radioactive waste management, are essential to ensure the required integrity of the system. As with any other human activity, improvements in technology and economics may be possible and secondary problems avoided. Improvements and confirmation of the efficiency of processes and reduction of uncertainties can only be achieved by continued active research, development and demonstration, which are the goals of many national programmes. International co-operation, also in the form of reviews, can contribute to increasing confidence in the ongoing work. The problem of radioactive wastes is not a unique one; it may be compared with other problems of toxic wastes resulting from many other

  14. Encapsulation of nuclear wastes

    International Nuclear Information System (INIS)

    Intermediate-level radioactive wastes produced in the day-to-day operation of a nuclear power plant may be incorporated into a thermosettable resin by mixing aqueous wastes with a vinyl ester resin, an unsaturated polyester resin, or a mixture of the two, and curing the resulting water-in-oil emulsion at temperatures below 1000C. The wastes may be either solutions or suspensions of inorganic or organic compounds derived from evaporation, flocculation, coagulation, filtration, ion exchange, or other treatment processes. (LL)

  2. Certification Plan, low-level waste Hazardous Waste Handling Facility

    International Nuclear Information System (INIS)

    The purpose of this plan is to describe the organization and methodology for the certification of low-level radioactive waste (LLW) handled in the Hazardous Waste Handling Facility (HWHF) at Lawrence Berkeley Laboratory (LBL). This plan also incorporates the applicable elements of waste reduction, which include both up-front minimization and end-product treatment to reduce the volume and toxicity of the waste; segregation of the waste as it applies to certification; an executive summary of the Waste Management Quality Assurance Implementing Management Plan (QAIMP) for the HWHF and a list of the current and planned implementing procedures used in waste certification. This plan provides guidance from the HWHF to waste generators, waste handlers, and the Waste Certification Specialist to enable them to conduct their activities and carry out their responsibilities in a manner that complies with the requirements of WHC-WAC. Waste generators have the primary responsibility for the proper characterization of LLW. The Waste Certification Specialist verifies and certifies that LBL LLW is characterized, handled, and shipped in accordance with the requirements of WHC-WAC. Certification is the governing process in which LBL personnel conduct their waste generating and waste handling activities in such a manner that the Waste Certification Specialist can verify that the requirements of WHC-WAC are met

  3. Hanford Waste Management Plan, 1987

    International Nuclear Information System (INIS)

    The purpose of the Hanford Waste Management Plan (HWMP) is to provide an integrated plan for the safe storage, interim management, and disposal of existing waste sites and current and future waste streams at the Hanford Site. The emphasis of this plan is, however, on the disposal of Hanford Site waste. The plans presented in the HWMP are consistent with the preferred alternative which is based on consideration of comments received from the public and agencies on the draft Hanford Defense Waste Environmental Impact Statement (HDW-EIS). Low-level waste was not included in the draft HDW-EIS whereas it is included in this plan. The preferred alternative includes disposal of double-shell tank waste, retrievably stored and newly generated TRU waste, one pre-1970 TRU solid waste site near the Columbia River and encapsulated cesium and strontium waste

  4. Hanford Site Secondary Waste Roadmap

    Energy Technology Data Exchange (ETDEWEB)

    Westsik, Joseph H.

    2009-01-29

    Summary The U.S. Department of Energy (DOE) is making plans to dispose of 54 million gallons of radioactive tank wastes at the Hanford Site near Richland, Washington. The high-level wastes and low-activity wastes will be vitrified and placed in permanent disposal sites. Processing of the tank wastes will generate secondary wastes, including routine solid wastes and liquid process effluents, and these need to be processed and disposed of also. The Department of Energy Office of Waste Processing sponsored a meeting to develop a roadmap to outline the steps necessary to design the secondary waste forms. Representatives from DOE, the U.S. Environmental Protection Agency, the Washington State Department of Ecology, the Oregon Department of Energy, Nuclear Regulatory Commission, technical experts from the DOE national laboratories, academia, and private consultants convened in Richland, Washington, during the week of July 21-23, 2008, to participate in a workshop to identify the risks and uncertainties associated with the treatment and disposal of the secondary wastes and to develop a roadmap for addressing those risks and uncertainties. This report describes the results of the roadmap meeting in Richland. Processing of the tank wastes will generate secondary wastes, including routine solid wastes and liquid process effluents. The secondary waste roadmap workshop focused on the waste streams that contained the largest fractions of the 129I and 99Tc that the Integrated Disposal Facility risk assessment analyses were showing to have the largest contribution to the estimated IDF disposal impacts to groundwater. Thus, the roadmapping effort was to focus on the scrubber/off-gas treatment liquids with 99Tc to be sent to the Effluent Treatment Facility for treatment and solidification and the silver mordenite and carbon beds with the captured 129I to be packaged and sent to the IDF. At the highest level, the secondary waste roadmap includes elements addressing regulatory and

  5. Nuclear Waste and Ethics

    Energy Technology Data Exchange (ETDEWEB)

    2003-10-01

    In the past years in almost all conferences on storage of nuclear waste, ethics has been considered as an important theme. But what is ethics? We will first give a sketch of this branch of philosophy. We will then give a short explanation of the three principal ethical theories. In the discussion about storage of nuclear waste, the ethical theory of utilitarianism is often implicitly invoked. In this system future generations weigh less heavily than the present generation, so that people of the future are not considered as much as those now living. We reject this form of reasoning. The discussion about nuclear waste is also sometimes pursued from ethical points of departure such as equality and justice. But many loose ends remain in these arguments, which gives rise to the question of whether the production and storage of nuclear waste is responsible.

  6. Waste form development

    International Nuclear Information System (INIS)

    In this program, contemporary solidification agents are being investigated relative to their applications to major fuel cycle and non-fuel cycle low-level waste (LLW) streams. Work is being conducted to determine the range of conditions under which these solidification agents can be applied to specific LLW streams. These studies are directed primarily towards defining operating parameters for both improved solidification of problem wastes and solidification of new LLW streams generated from advanced volume reduction technologies. Work is being conducted to measure relevant waste form properties. These data will be compiled and evaluated to demonstrate compliance with waste form performance and shallow land burial acceptance criteria and transportation requirements (both as they exist and as they are modified with time). 6 tables

  8. Developing hazardous waste programs

    Science.gov (United States)

    Showstack, Randy

    Developing a fully operational hazardous waste regulatory system requires at least 10 to 15 years—even in countries with strong legal and bureaucratic institutions, according to a report on "The Evolution of Hazardous Waste Programs," which was funded by Resources for the Future (RFF) and the World Bank's South Asia Environment Group, and issued on June 4.The report, which compares the experiences of how four developed and four developing countries have created hazardous waste programs, indicates that hazardous waste issues usually do not become a pressing environmental issue until after countries have dealt with more direct threats to public health, such as contaminated drinking water and air pollution. The countries examined include Indonesia, Thailand, Germany, and the United States.

  9. Radioactive waste processing device

    International Nuclear Information System (INIS)

    Liquid wastes are supplied to a ceramic filter to conduct filtration. In this case, a device for adding a powdery inorganic ion exchanger is disposed to the upstream of the ceramic filter. When the powdery inorganic ion exchanger is charged to the addition device, it is precoated to the surface of the ceramic filter, to conduct separation of suspended matters and separation of ionic nuclides simultaneously. Liquid wastes returned to a collecting tank are condensed while being circulated between the ceramic filter and the tank and then contained in a condensation liquid waste tank. With such a constitution, both of radioactive nuclides accompanied by suspended matters in the radioactive liquid wastes and ionic nuclides can be captured efficiently. (T.M.)

  10. Disposal of Radioactive Waste

    International Nuclear Information System (INIS)

    This Safety Requirements publication applies to the disposal of radioactive waste of all types by means of emplacement in designed disposal facilities, subject to the necessary limitations and controls being placed on the disposal of the waste and on the development, operation and closure of facilities. The classification of radioactive waste is discussed. This Safety Requirements publication establishes requirements to provide assurance of the radiation safety of the disposal of radioactive waste, in the operation of a disposal facility and especially after its closure. The fundamental safety objective is to protect people and the environment from harmful effects of ionizing radiation. This is achieved by setting requirements on the site selection and evaluation and design of a disposal facility, and on its construction, operation and closure, including organizational and regulatory requirements.

  15. ORNL radioactive waste operations

    International Nuclear Information System (INIS)

    Since its beginning in 1943, ORNL has generated large amounts of solid, liquid, and gaseous radioactive waste material as a by-product of the basic research and development work carried out at the laboratory. The waste system at ORNL has been continually modified and updated to keep pace with the changing release requirements for radioactive wastes. Major upgrading projects are currently in progress. The operating record of ORNL waste operation has been excellent over many years. Recent surveillance of radioactivity in the Oak Ridge environs indicates that atmospheric concentrations of radioactivity were not significantly different from other areas in East Tennesseee. Concentrations of radioactivity in the Clinch River and in fish collected from the river were less than 4% of the permissible concentration and intake guides for individuals in the offsite environment. While some radioactivity was released to the environment from plant operations, the concentrations in all of the media sampled were well below established standards

  16. Waste package characterisation

    International Nuclear Information System (INIS)

    Radioactive wastes originating from the hot labs of the Belgian Nuclear Research Centre SCK-CEN contain a wide variety of radiotoxic substances. The accurate characterisation of the short- and long-term radiotoxic components is extremely difficult but required in view of geological disposal. This paper describes the methodology which was developed and adopted to characterise the high- and medium-level waste packages at the SCK-CEN hot laboratories. The proposed method is based on the estimation of the fuel inventory evacuated in a particular waste package; a calculation of the relative fission product contribution on the fuel fabrication and irradiation footing; a comparison of the calculated, as expected, dose rate and the real measured dose rate of the waste package. To cope with the daily practice an appropriate fuel inventory estimation route, a user friendly computer programme for fission product and corresponding dose rate calculation, and a simple dose rate measurement method have been developed and implemented

    International Nuclear Information System (INIS)

    The criteria involved in selecting sites for disposal of low and short-lived intermediate-level radioactive wastes are explained. The wastes and the sources are identified and the current procedure for their disposal, at Drigg, next to the Sellafield reprocessing plant, is given. If alternative sites could be found for non-Sellafield-produced wastes the lifetime of the Drigg site could be extended. The sites chosen by NIREX (Nuclear Industry Radioactive Waste Executive) have to be cost effective. Indeed, those identified are conveniently situated and would not incur excessive transport costs. However, more remote sites may have to be chosen, even at greater transport cost, because of public protests. Even this may not be satisfactory because the transportation itself incurs risks. (UK)

  19. Immobilisation of hazardous waste

    International Nuclear Information System (INIS)

    Hazardous waste, e.g. radioactive waste, particularly that containing caesium-137, is immobilised by mixing with cement and solidifiable organic polymeric material. When first mixed, the organic material is preferably liquid and at this time can be polymerisable or already polymerised. The hardening can result from cooling or further polymerisation e.g. cross-linking. The organic material may be wax, or a polyester which may be unsaturated and cross-linkable by reaction with styrene. (author)

  2. Disposing of fluid wastes

    International Nuclear Information System (INIS)

    Toxic liquid waste, eg liquid radioactive waste, is disposed of by locating a sub-surface stratum which, before removal of any fluid, has a fluid pressure in the pores thereof which is less than the hydrostatic pressure which is normal for a stratum at that depth in the chosen area, and then feeding the toxic liquid into the stratum at a rate such that the fluid pressure in the stratum never exceeds the said normal hydrostatic pressure.

  3. Nuclear waste and hazardous waste in the public perception

    International Nuclear Information System (INIS)

    The disposal of nuclear waste has gained attention of the public for decades. Accordingly, nuclear waste has been a prominent issue in natural, engineer and social science for many years. Although bearing risks for todays and future generations hazardous waste in contrast is much less an issue of public concern. In 2011, we conducted a postal survey among Swiss Germans (N = 3.082) to learn more about, how nuclear waste is perceived against hazardous waste. We created a questionnaire with two versions, nuclear waste and hazardous waste, respectively. Each version included an identical part with well-known explanatory factors for risk perception on each of the waste types separately and additional questions directly comparing the two waste types. Results show that basically both waste types are perceived similarly in terms of risk/benefit, emotion, trust, knowledge and responsibility. However, in the direct comparison of the two waste types a complete different pattern can be observed: Respondents perceive nuclear waste as more long-living, more dangerous, less controllable and it, furthermore, creates more negative emotions. On the other hand, respondents feel more responsible for hazardous waste and indicate to have more knowledge about this waste type. Moreover, nuclear waste is perceived as more carefully managed. We conclude that mechanisms driving risk perception are similar for both waste types but an overarching negative image of nuclear waste prevails. We propose that hazardous waste should be given more attention in the public as well as in science which may have implications on further management strategies of hazardous waste.

    The disposal of nuclear waste has gained attention of the public for decades. Accordingly, nuclear waste has been a prominent issue in natural, engineer and social science for many years. Although bearing risks for todays and future generations hazardous waste in contrast is much less an issue of public concern. In 2011, we conducted a postal survey among Swiss Germans (N = 3.082) to learn more about, how nuclear waste is perceived against hazardous waste. We created a questionnaire with two versions, nuclear waste and hazardous waste, respectively. Each version included an identical part with well-known explanatory factors for risk perception on each of the waste types separately and additional questions directly comparing the two waste types. Results show that basically both waste types are perceived similarly in terms of risk/benefit, emotion, trust, knowledge and responsibility. However, in the direct comparison of the two waste types a complete different pattern can be observed: Respondents perceive nuclear waste as more long-living, more dangerous, less controllable and it, furthermore, creates more negative emotions. On the other hand, respondents feel more responsible for hazardous waste and indicate to have more knowledge about this waste type. Moreover, nuclear waste is perceived as more carefully managed. We conclude that mechanisms driving risk perception are similar for both waste types but an overarching negative image of nuclear waste prevails. We propose that hazardous waste should be given more attention in the public as well as in science which may have implications on further management strategies of hazardous waste.

  5. Management of hospital radioactive wastes

    International Nuclear Information System (INIS)

    The general structure of a regulatory scheme for the management of hospital radioactive wastes is presented. The responsabilities of an institution in the radioactive waste management, and storage conditions are defined. The radioactive wastes are classified in physical terms, and the criteria for evaluating the activity of solid wastes are described. The container characteristics and, the types of treatments given to the wastes are specified. (M.C.K.)

  6. Waste package scenario modelling

    International Nuclear Information System (INIS)

    UK Nirex has supported a programme of work to develop models describing the post-closure evolution of intermediate-level waste packages with the objectives of: - providing support and justification for the parameters and representations used in performance assessment models; - informing future model development and packaging advice. Scenarios for the potential evolution of a waste package were developed and modelled taking explicit account of waste package heterogeneity and the time-dependence of the physical and chemical characteristics of the system. The modelling work highlighted the treatment of organic complexants and the representation of physical containment as two areas in which the impacts of time dependence and package scale heterogeneity might be particularly significant. A subsequent study of the impact of organic complexants emphasised the importance of heterogeneity in package inventory in determining the radionuclide release from the near field. The degree of containment afforded by the wasteform and the waste container has been investigated as part of a study to develop a preliminary understanding of the mixing scales within the repository. The study suggests that the most important control on the release of radionuclides from the waste packages is the integrity of the waste encapsulation grout. Interactions between neighbouring packages are to be expected, but the degree to which homogeneous (well mixed) conditions develop may be limited in both time and space. (author)

  7. International waste management

    International Nuclear Information System (INIS)

    The growth of nuclear power depends very much on concerns and problems of radioactive waste disposal. The safe disposal of radioactive wastes is a vital issue. Conscious that its Member States have had three decades' experience in managing wastes, the Agency considered it timely to review and assess the present status and knowledge of the subject, and that it was particularly important to note any deficiencies in order to re-examine current practices and technology. The Agency therefore decided to convene an international conference on the subject of waste management. The conference will be held in Seattle, Washington State, USA, from 16 to 20 May. The Agency has held several symposia and international meetings in the past covering different aspects of radioactive waste management. There has, however, not been an IAEA conference so far giving summary reviews of the many technical, environmental, regulatory, institutional, legal, and economic aspects of waste management, their interrelationships, and their implications for the development of nuclear power. The broad objectives of the conference are: to provide a forum for international exchange of information for policy-makers and technical experts; to highlight issues of current importance; and to identify possible approaches to their solution on the basis of the knowledge accumulated from past experience, research and development, and policy considerations

    A barrel gamma scanning unit has been in use at the VAK for the classification of radioactive waste materials since 1998. The unit provides the facility operator with the data required for classification of waste barrels. Once these data have been entered into the AVK data processing system, the radiological status of raw waste as well as pre-treated and processed waste can be tracked from the point of origin to the point at which the waste is delivered to a final storage. Since the barrel gamma scanning unit was commissioned in 1998, approximately 900 barrels have been measured and the relevant data required for classification collected and analyzed. Based on the positive results of experience in the use of the mobile barrel gamma scanning unit, the VAK now offers the classification of barrels as a service to external users. Depending upon waste quantity accumulation, this measurement unit offers facility operators a reliable and time-saving and cost-effective means of identifying and documenting the radioactivity inventory of barrels scheduled for final storage.

  9. Storage of radioactive wastes

    International Nuclear Information System (INIS)

    Even if the best waste minimization measures are undertaken throughout radioisotope production or usage, significant radioactive wastes arise to make management measures essential. For developing countries with low isotope usage and little or no generation of nuclear materials, it may be possible to handle the generated waste by simply practicing decay storage for several half-lives of the radionuclides involved, followed by discharge or disposal without further processing. For those countries with much larger facilities, longer lived isotopes are produced and used. In this situation, storage is used not only for decay storage but also for in-process retention steps and for the key stage of interim storage of conditioned wastes pending final disposal. The report will serve as a technical manual providing reference material and direct step-by-step know-how to staff in radioisotope user establishments and research centres in the developing Member States without nuclear power generation. Considerations are limited to the simpler storage facilities. The restricted quantities and low activity associated with the relevant wastes will generally permit contact-handling and avoid the need for shielding requirements in the storage facilities or equipment used for handling. A small quantity of wastes from some radioisotope production cells and from reactor cooling water treatment may contain sufficient short lived activity from activated corrosion products to require some separate decay storage before contact-handling is suitable. 16 refs, 12 figs, 8 tabs

    2009-01-01

    Every year almost 45 billion kg of fresh vegetables, fruits, milk, and grain products is lost to waste in the United States. According to the EPA, the disposal of this costs approximately $1 billion. In the United Kingdom, 20 million ton of food waste is produced annually. Every tonne of food waste means 4.5 ton of CO(2) emissions. The food wastes are generated largely by the fruit-and-vegetable/olive oil, fermentation, dairy, meat, and seafood industries. The aim of this chapter is to emphasize existing trends in the food waste processing technologies during the last 15 years. The chapter consists of three major parts, which distinguish recovery of added-value products (the upgrading concept), the food waste treatment technologies as well as the food chain management for sustainable food system development. The aim of the final part is to summarize recent research on user-oriented innovation in the food sector, emphasizing on circular structure of a sustainable economy. PMID:19878858

  11. Waste Isolation Pilot Plant simulated waste compositions and mechanical properties

    International Nuclear Information System (INIS)

    Analyses of the final state of collapse of various types of contact-handled waste drums are required to assess of the performance of the waste storage areas in the Waste Isolation Pilot Plant. To provide data for calculations, tests must use simulated, instead of actual waste. Data on the contents of the principal categories of contact-handled transuranic waste from the Idaho National Engineering Laboratory were used to define standard compositions of simulated waste. Categories of baseline waste will be created by mixing appropriate amounts of the simulants together. Selection of materials is discussed. Methods for estimating the consolidation characteristics of simulated waste are also described. Theoretical solid densities, theoretical solid compressibilities, and initial void volumes of various waste components are estimated, and a method for estimating consolidation curves in the absence of experimental data is described. 9 refs., 14 figs., 11 tabs

  12. Training waste generators: The first responder in proper waste management

    International Nuclear Information System (INIS)

    Dealing with waste effectively requires a ''cradle to grave'' approach to waste management. The first step in that chain of custody is the waste generator. The waste generator plays the key role in the correct identification, packaging, and disposal of waste. The Technical Resources and Training Section at the Oak Ridge National Laboratory (ORNL) has developed several short training programs for waste generators. This training presents a consistent approach to proper handling of waste within the ORNL waste management system. This training has been developed for generators of solid low-level radioactive waste, hazardous and mixed waste, and transuranic waste. In addition to the above, a Waste Minimization training program has been developed for use by all organizations at ORNL who generate any type of hazardous waste. These training programs represent a combined effort of the training staff and the technical staff to assure that all ORNL staff accept their responsibility for handling all types of radioactive and hazardous wastes correctly from its generation to its disposal. 4 refs

  13. Certification Plan, Radioactive Mixed Waste Hazardous Waste Handling Facility

    International Nuclear Information System (INIS)

    The purpose of this plan is to describe the organization and methodology for the certification of radioactive mixed waste (RMW) handled in the Hazardous Waste Handling Facility at Lawrence Berkeley Laboratory (LBL). RMW is low-level radioactive waste (LLW) or transuranic (TRU) waste that is co-contaminated with dangerous waste as defined in the Westinghouse Hanford Company (WHC) Solid Waste Acceptance Criteria (WAC) and the Washington State Dangerous Waste Regulations, 173-303-040 (18). This waste is to be transferred to the Hanford Site Central Waste Complex and Burial Grounds in Hanford, Washington. This plan incorporates the applicable elements of waste reduction, which include both up-front minimization and end-product treatment to reduce the volume and toxicity of the waste; segregation of the waste as it applies to certification; an executive summary of the Waste Management Quality Assurance Implementing Management Plan (QAIMP) for the HWHF (Section 4); and a list of the current and planned implementing procedures used in waste certification

    2001-09-01

    This feasibility study report presents a draft design of the Vitrified Waste Interim Storage Facility (VWISF), which is one of three subprojects of the Idaho Waste Vitrification Facilities (IWVF) project. The primary goal of the IWVF project is to design and construct a treatment process system that will vitrify the sodium-bearing waste (SBW) to a final waste form. The project will consist of three subprojects that include the Waste Collection Tanks Facility, the Waste Vitrification Facility (WVF), and the VWISF. The Waste Collection Tanks Facility will provide for waste collection, feed mixing, and surge storage for SBW and newly generated liquid waste from ongoing operations at the Idaho Nuclear Technology and Engineering Center. The WVF will contain the vitrification process that will mix the waste with glass-forming chemicals or frit and turn the waste into glass. The VWISF will provide a shielded storage facility for the glass until the waste can be disposed at either the Waste Isolation Pilot Plant as mixed transuranic waste or at the future national geological repository as high-level waste glass, pending the outcome of a Waste Incidental to Reprocessing determination, which is currently in progress. A secondary goal is to provide a facility that can be easily modified later to accommodate storage of the vitrified high-level waste calcine. The objective of this study was to determine the feasibility of the VWISF, which would be constructed in compliance with applicable federal, state, and local laws. This project supports the Department of Energy’s Environmental Management missions of safely storing and treating radioactive wastes as well as meeting Federal Facility Compliance commitments made to the State of Idaho.

    2008-07-17

    This study evaluates parameters relevant to River Protection Project secondary waste streams generated during Early Low Activity Waste operations and recommends a strategy for secondary waste management that considers groundwater impact, cost, and programmatic risk. The recommended strategy for managing River Protection Project secondary waste is focused on improvements in the Effiuent Treatment Facility. Baseline plans to build a Solidification Treatment Unit adjacent to Effluent Treatment Facility should be enhanced to improve solid waste performance and mitigate corrosion of tanks and piping supporting the Effiuent Treatment Facility evaporator. This approach provides a life-cycle benefit to solid waste performance and reduction of groundwater contaminants.

  1. Drying plant waste

    International Nuclear Information System (INIS)

    Under the repository storage conditions of Eram and Konrad, waste packages designed for permanent storage must not contain or release freely mobile liquids, except for the minimum residues attainable by reasonable efforts or unavoidable. In accordance with a directive issued by the German Federal Ministry for the Environment (BMU), waste conditioning must be carried out so as to minimize waste volumes and, if possible, on the site where the waste arises. Liquid waste is conditioned most effectively by drying. At the present time, various different processes for drying liquid waste are employed as reflected by the state of the art: The Robe process; roller drying; the RDA process; Favorit; in-drum drying; and HPA liquid waste drying with make-up feed. The HPA process offers these advantages: Drying under atmospheric conditions, which means high level of dryness (freely mobile and releasable water is removed); the residual water content is 10%; isothermal drying by hot air, which produces monoliths guaranteeing high strength of the final product and maximum volume reduction by simple process technology; there is no local superheating; contamination hazards are minimized by drying in the repository storage package; consequently, there is no filling step, and vapors are collected separately; the level of automation is high, e.g. with fully automated control from a shielded control console with video monitoring capability; the high standard of documentation allows instant process visualization throughout the drying process along with easy process control; high flexibility is achieved in mobile and stationary plants, respectively, with the added possibility of service functions being provided; modular small compact versions are also available.

  2. Waste form product characteristics

    International Nuclear Information System (INIS)

    The Department of Energy has operated nuclear facilities at the Idaho National Engineering Laboratory (INEL) to support national interests for several decades. Since 1953, it has supported the development of technologies for the storage and reprocessing of spent nuclear fuels (SNF) and the resultant wastes. However, the 1992 decision to discontinue reprocessing of SNF has left nearly 768 MT of SNF in storage at the INEL with unspecified plans for future dispositioning. Past reprocessing of these fuels for uranium and other resource recovery has resulted in the production of 3800 M3 calcine and a total inventory of 7600 M3 of radioactive liquids (1900 M3 destined for immediate calcination and the remaining sodium-bearing waste requiring further treatment before calcination). These issues, along with increased environmental compliance within DOE and its contractors, mandate operation of current and future facilities in an environmentally responsible manner. This will require satisfactory resolution of spent fuel and waste disposal issues resulting from the past activities. A national policy which identifies requirements for the disposal of SNF and high level wastes (HLW) has been established by the Nuclear Waste Policy Act (NWPA) Sec.8,(b) para(3)) [1982]. The materials have to be conditioned or treated, then packaged for disposal while meeting US Environmental Protection Agency (EPA) and Nuclear Regulatory Commission (NRC) regulations. The spent fuel and HLW located at the INEL will have to be put into a form and package that meets these regulatory criteria. The emphasis of Idaho Chemical Processing Plant (ICPP) future operations has shifted toward investigating, testing, and selecting technologies to prepare current and future spent fuels and waste for final disposal. This preparation for disposal may include mechanical, physical and/or chemical processes, and may differ for each of the various fuels and wastes

  5. Perspectives on sustainable waste management.

    Castaldi, Marco J

    2014-01-01

    Sustainable waste management is a goal that all societies must strive to maintain. Currently nearly 80% of global wastes are sent to landfill, with a significant amount lacking proper design or containment. The increased attention to environmental impacts of human activities and the increasing demand for energy and materials have resulted in a new perspective on waste streams. Use of waste streams for energy and materials recovery is becoming more prevalent, especially in developed regions of the world, such as Europe, the United States, and Japan. Although currently these efforts have a small impact on waste disposal, use of waste streams to extract value very likely will increase as society becomes more aware of the options available. This review presents an overview of waste management with a focus on following an expanded waste hierarchy to extract value specifically from municipal solid waste streams. PMID:24910921

  6. Fernald waste management and disposition

    International Nuclear Information System (INIS)

    Historically waste management within the Department of Energy complex has evolved around the operating principle of packaging waste generated and storing until a later date. In many cases wastes were delivered to onsite waste management organizations with little or no traceability to origin of generation. Sites then stored their waste for later disposition offsite or onsite burial. While the wastes were stored, sites incurred additional labor costs for maintaining, inspecting and repackaging containers and capital costs for storage warehouses. Increased costs, combined with the inherent safety hazards associated with storage of hazardous material make these practices less attractive. This paper will describe the methods used at the Department of Energy's Fernald site by the Waste Programs Management Division to integrate with other site divisions to plan in situ waste characterization prior to removal. This information was utilized to evaluate and select disposal options and then to package and ship removed wastes without storage

Through the planning to address the company's accumulation of radioactive waste, more and more waste repository issue of storage space is shrinking each year. Planning is mainly to establish compression volume reduction system, to be accumulated to a certain amount of radioactive waste, the compressed volume reduction package, packaged material blocks passing through the surface contamination testing was conducted after the weighing to measure, and paste the labels, establishing a database and record sets account, record the weight, type, date, etc. after the warehouse store. Would be a good package of radioactive solid waste brought to the state designated for storage of radioactive waste storage sites. By planning the company's radioactive solid waste control and management has been continued to improve. (authors)

  8. Waste characterization: What's on second?

    International Nuclear Information System (INIS)

    Waste characterization is the process whereby the physical properties and chemical composition of waste are determined. Waste characterization is an important element which is necessary to certify that waste meets the acceptance criteria for storage, treatment, or disposal. Department of Energy (DOE) Orders list and describe the germane waste form, package, and container criteria for the storage of both solid low-level waste package, and container criteria for the storage of both solid low-level waste (SLLW) and transuranic (TRU) waste, including chemical composition and compatibility, hazardous material content (e.g., lead), fissile material content, radioisotopic inventory, particulate content, equivalent alpha activity, thermal heat output, and absence of free liquids, explosives, and compressed gases. At the Oak Ridge National Laboratory (ORNL), the responsibility for waste characterization begins with the individual or individuals who generate the waste. The generator must be able to document the type and estimate the quantity of various materials (e.g., waste forms -- physical characteristics, chemical composition, hazardous materials, major radioisotopes) which have been placed into the waste container. Analyses of process flow sheets and a statistically valid sampling program can provide much of the required information as well as a documented level of confidence in the acquired data. A program is being instituted in which major generator facilities perform radionuclide assay of small packets of waste prior to being placed into a waste drum. 17 refs., 1 fig., 4 tabs

  9. Hospital waste management in Lebanon

    International Nuclear Information System (INIS)

    Hospital wastes comprises approximately 80% domestic waste components, also known as non-risk waste and 20% hazardous or risk waste. The 20% of the hospital waste stream or the risk waste (also known as infectious, medical, clinical wastes) comprises components which could be potentially contaminated with infections, chemical or radioactive agents. Therefore, it should be handled and disposed of in such a manner as to minimize potential human exposure and cross-contamination. Hospital risk waste and be subdivided into seven general categories as follows: infections, anatomical/pathological, chemical, pharmaceutical, radioactive waste, sharps and pressurised containers. These waste categories are generated by many types of health care establishments, including hospitals, clinics, infirmaries.... The document presents also tables of number of hospitals and estimated bed number in different regions in Lebanon; estimated hospital risk and non-risk waste generation per tonnes per day for the years 1998 until 2010 and finally sensitivity analysis of estimated generation of hospital risk waste in Lebanon per tonnes per day for the years 1998 until 2010. The management, treatment and disposal of hospital risk waste constitute important environmental and public safety issues. It is recognised that there is alack of infrastructure for the safe and environmentally acceptable disposal of hospital waste in Lebanon

  10. Mixed waste characterization reference document

    International Nuclear Information System (INIS)

    Waste characterization and monitoring are major activities in the management of waste from generation through storage and treatment to disposal. Adequate waste characterization is necessary to ensure safe storage, selection of appropriate and effective treatment, and adherence to disposal standards. For some wastes characterization objectives can be difficult and costly to achieve. The purpose of this document is to evaluate costs of characterizing one such waste type, mixed (hazardous and radioactive) waste. For the purpose of this document, waste characterization includes treatment system monitoring, where monitoring is a supplement or substitute for waste characterization. This document establishes a cost baseline for mixed waste characterization and treatment system monitoring requirements from which to evaluate alternatives. The cost baseline established as part of this work includes costs for a thermal treatment technology (i.e., a rotary kiln incinerator), a nonthermal treatment process (i.e., waste sorting, macronencapsulation, and catalytic wet oxidation), and no treatment (i.e., disposal of waste at the Waste Isolation Pilot Plant (WIPP)). The analysis of improvement over the baseline includes assessment of promising areas for technology development in front-end waste characterization, process equipment, off gas controls, and monitoring. Based on this assessment, an ideal characterization and monitoring configuration is described that minimizes costs and optimizes resources required for waste characterization

  11. Integrated waste management - Looking beyond the solid waste horizon

    International Nuclear Information System (INIS)

    Waste as a management issue has been evident for over four millennia. Disposal of waste to the biosphere has given way to thinking about, and trying to implement, an integrated waste management approach. In 1996 the United Nations Environmental Programme (UNEP) defined 'integrated waste management' as 'a framework of reference for designing and implementing new waste management systems and for analysing and optimising existing systems'. In this paper the concept of integrated waste management as defined by UNEP is considered, along with the parameters that constitute integrated waste management. The examples used are put into four categories: (1) integration within a single medium (solid, aqueous or atmospheric wastes) by considering alternative waste management options (2) multi-media integration (solid, aqueous, atmospheric and energy wastes) by considering waste management options that can be applied to more than one medium (3) tools (regulatory, economic, voluntary and informational) and (4) agents (governmental bodies (local and national), businesses and the community). This evaluation allows guidelines for enhancing success: (1) as experience increases, it is possible to deal with a greater complexity; and (2) integrated waste management requires a holistic approach, which encompasses a life cycle understanding of products and services. This in turn requires different specialisms to be involved in the instigation and analysis of an integrated waste management system. Taken together these advance the path to sustainability

  12. Management on radioactive wastes

    International Nuclear Information System (INIS)

    The basic philosophy governing the radioactive waste management activities in India is to concentrate and contain as much activity as possible and to discharge to the environment only such of these streams that have radioactive content much below the nationally and internationally accepted standards. The concept of ''Zero Release'' is also kept in view. At Tarapur, the effluents are discharged into coastal waters after the radioactivity of the effluents is brought down by a factor 100. The effluents fΩm Rajasthan reactors are discharged into a lake keeping their radioactivity well within permissible limits and a solar evaporation plant is being set up. The plant, when it becomes operational, will be a step towards the concept of ''Zero Release''. At Kalpakkam, the treated wastes are proposed to be diluted by circulating sea water and discharged away from the shore through a long pipe. At Narora, ion exchange followed by chemical precipitation is to be employed to treat effluents and solar evaporation process for total containment. Solid wastes are stored/dispsed in the concrete trenches, underground with the water proofing of external surfaces and the top of the trench is covered with concrete. Highly active wastes are stored/disposed in tile holes which are vaults made of steel-lined, reinforced concrete pipes. Gas cleaning, dilution and dispersion techniques are adopted to treat gaseous radioactive wastes. (M.G.B.)

  13. Waste management at KKP

    International Nuclear Information System (INIS)

    The smooth management of radioactive plant waste is an integral, essential part of safe and economic operation of a nuclear power plant. The Philippsburg Nuclear Power Station (KKP) addressed these problems early on. The stationary facilities installed, with an organization established in the lights of the objectives to be met, allow problems to be solved largely independent of external factors and make for operational flexibility and optimum utilization of plant and personnel capacities. The good performance achieved in volume reduction and product quality of the conditioned radioactive waste justifies the capital investments made. In this way, KKP has met the ecological and economic requirements of orderly waste management. At KKP, waste management is considered an interdisciplinary duty. Existing resources in KKP's organization were used to achieve synergy effects. The Central Monitoring Unit is responsible for the cooperation of all groups involved with the objective of generating a product fit for final storage. The necessary coordination and monitoring efforts are made by a small team of specialists with extensive know-how in waste management. Four persons are responsible for coordination and monitoring, and another ten or twelve persons for direct execution of the work. (orig.)

  14. Radioactive wastes handling facility

    International Nuclear Information System (INIS)

    There are disposed an area where a conveyor is disposed for separating miscellaneous radioactive solid wastes such as metals, on area for operators which is disposed in the direction vertical to the transferring direction of the conveyor, an area for receiving the radioactive wastes and placing them on the conveyor and an area for collecting the radioactive wastes transferred by the conveyor. Since an operator can conduct handling while wearing a working cloth attached to a partition wall as he wears his ordinary cloth, the operation condition can be improved and the efficiency for the separating work can be improved. When the area for settling conveyors and the area for the operators is depressurized, cruds on the surface of the wastes are not released to the outside and the working clothes can be prevented from being involved. Since the wastes are transferred by the conveyor, the operator's moving range is reduced, poisonous materials are fallen and moved through a sliding way to an area for collecting materials to be separated. Accordingly, the materials to be removed can be accumulated easily. (N.H.)

    Sweden has developed a comprehensive system for the management of all wastes arising from its nuclear power production. An interim storage for spent nuclear fuel is in operation since 1985. A repository for low and medium level waste has been constructed and is in operation since 1988. Transportation of the fuel and other radioactive wastes is made by a sea transport system. The existing facilities will with some moderate expansion be sufficient to handle all radioactive wastes for a long time. An encapsulation plant for spent nuclear fuel and a repository for final disposal of a limited amount of spent fuel is planned to be built till 2008. In the repository the fuel will be isolated by multiple engineered and geological barriers. The ongoing waste management RD and D-programme is mainly concerned with questions related to the encapsulation of fuel and construction of such a repository in the granitic bedrock in Sweden. During the 1990s the emphasize will be on finalizing the development and the design of the needed facilities and on the characterization of candidate repository sites. The cost for spent fuel management including final disposal has been calculated to 4800 SEK/kg U. (author). 6 figs

  20. Waste segregation procedures and benefits

    International Nuclear Information System (INIS)

    Segregation is a critical first step in handling hazardous and radioactive materials to minimize the generation of regulated wastes. In addition, segregation can significantly reduce the complexity and the total cost of managing waste. Procedures at Sandia National Laboratories, Albuquerque require that wastes be segregated, first, by waste type (acids, solvents, low level radioactive, mixed, classified, etc.). Higher level segregation requirements, currently under development, are aimed at enhancing the possibilities for recovery, recycle and reapplication; reducing waste volumes; reducing waste disposal costs, and facilitating packaging storage, shipping and disposal. 2 tabs

  1. Mixed waste, a generator's perspective

    International Nuclear Information System (INIS)

    Compounds labelled with carbon-14 and tritium are used worldwide as tools for fundamental research in academic biochemical and medical research laboratories. Mixed waste, waste that is both hazardous and radioactive, is generated in the manufacture of these vital products. DuPont NEN Research Products has reduced the mixed waste originating in labelled chemicals' manufacture by 30% over the past year. Application of innovative waste minimization strategies will continue to reduce the volume of waste, but not eliminate it. As long as radiolabeled compounds are synthesized, mixed waste will be generated and disposal or treatment capacity will be needed

  2. Radioactive waste package acceptance criteria

    International Nuclear Information System (INIS)

    Preliminary acceptance criteria have been developed for packages containing nuclear waste which must be stored or disposed of by the US Department of Energy. Acceptance criteria are necessary to ensure that the waste packages are compatible with all elements of the Waste Management System. The acceptance criteria are subject to revision since many of the constraints that will be imposed on the waste packages by the Waste Management System have either not been defined or are being revised. Delineation of the acceptance criteria will provide bases for handling, transporting and disposing of the commercial waste

    The Hanford Site Effluent Treatment Facility (ETF) currently treats aqueous waste streams generated during Site cleanup activities. When the Hanford Tank Waste Treatment and Immobilization Plant (WTP) begins operations, a liquid secondary waste (LSW) stream from the WTP will need to be treated. The volume of effluent for treatment at the ETF will increase significantly. Washington River Protection Solutions is implementing a Secondary Liquid Waste Immobilization Technology Development Plan to address the technology needs for a waste form and solidification process to treat the increased volume of waste planned for disposal at the Integrated Disposal Facility IDF). Waste form testing to support this plan is composed of work in the near term to demonstrate the waste form will provide data as input to a performance assessment (PA) for Hanford’s IDF.

    2004-01-01

    For many years, segregation of transuranic (TRU) waste at Technical Area 55 (TA-55) was based on the TRU Package Transporter-II (TRUPACT-II) Content Code (TRUCON Code)-dependent matrices, hazardous constituents, the nonhazardous nature of waste, nondestructive assay requirements, and other factors. This approach required well over a hundred active waste profiles for waste acceptance at the onsite treatment storage and disposal facility. Over the past few years, the profiling approach has evolved in an effort to make the waste disposition process more efficient. Based on interpretation of various requirements, TA-55 is further simplifying its waste management operations and plans to eventually have only a few tens of waste profiles to expedite the review and approval of drum data packages. Nondefense, or homogeneous, cemented, or vitrified wastes are excluded from discussion in this paper.

  5. Assay and RTR of solid waste management received TRU waste

    International Nuclear Information System (INIS)

    The Transuranic Storage and Assay Facility (TRUSAF) provides storage of Transuranic (TRU) and Transuranic Mixed (TRUM) waste from U.S. DOD and DOE offsite and onsite generators. In addition to storage, TRUSAF also performs assay and RTR (real time radiography) on each TRU drum with the intent of certification of the waste to WIPP-WAC (Waste Isolation Pilot Plant-Waste Acceptance Criteria) to allow eventual disposal of the TRU waste at WIPP. Due to the uncertainties associated with WIPP-WAC and the potential for all TRU WIPP-WAC certification at the generator or WRAP (Waste Receiving and Processing) facility, this study documents the requirements for TRU assay and RTR of all incoming TRU drums and establishes SWM (Solid Waste Management) policy on future assay and RTR of received TRU waste

  7. Hazardous wastes and waste oils in Austria. Compiled for the Austrian Federal Waste Management Plan 2001

    International Nuclear Information System (INIS)

    The Austrian Waste Management Act (AWG) entered into force on 1 July 1990. Paragraph 1 of the act defines the following objectives: to keep detrimental, unbeneficial or otherwise unhealthy influences on man, as well as on animals, plants, their living conditions and their natural environment as low as possible; to preserve raw material and energy resources; to keep the demand for landfill capacities as low as possible; to ensure that only such materials should remain as waste, the dumping of which does not present any potential hazard for future generations (precautionary principle). The waste management act thus places the highest priority on the protection of human beings and the environment and upon the preservation of natural resources. Accordingly, it must be the aim of waste management to handle waste in such a way that environmental pollution is kept as low as possible by prevention, recovery and disposal. Paragraph 5 of the Austrian waste management act stipulates that the Federal Minister of Agriculture, Forestry, Environment and Water Management has to issue the Federal Waste Management Plan in order to reach the objectives and observing the rules of modern waste management. Following the first waste management plan in 1992 an amendment is required every three years. This is why the Austrian Federal Environment Agency elaborated the following studies: waste generation, recovery and disposal in Austria; hazardous waste and waste oils in Austria; non-hazardous waste in Austria. Further information on waste management facilities in Austria is presented on our homepage (http://www.ubavie.gv.at). (author)

  8. High level nuclear wastes

    International Nuclear Information System (INIS)

    The transformations involved in the nuclear fuels during the burn-up at the power nuclear reactors for burn-up levels of 33.000 MWd/th are considered. Graphs and data on the radioactivity variation with the cooling time and heat power of the irradiated fuel are presented. Likewise, the cycle of the fuel in light water reactors is presented and the alternatives for the nuclear waste management are discussed. A brief description of the management of the spent fuel as a high level nuclear waste is shown, explaining the reprocessing and giving data about the fission products and their radioactivities, which must be considered on the vitrification processes. On the final storage of the nuclear waste into depth geological burials, both alternatives are coincident. The countries supporting the reprocessing are indicated and the Spanish programm defined in the Plan Energetico Nacional (PEN) is shortly reviewed. (author) 8 figs., 4 tabs

  9. Nuclear waste management

    International Nuclear Information System (INIS)

    Passage of the Nuclear Waste Policy Act by the Congress, December 20, 1982, in the waning hours of the 97th Congress, was a major milestone in the management of the Nation's spent fuel and high-level radioactive waste. The Congress -- and, subsequently, the President -- made a tough decision that this generation must bite the bullet and proceed with the development of a permanent waste disposal system for the protection of future generations. The Act was a result of several attempts by the Congress over a number of years to move to action on this important subject. President Reagan added his leadership to the task through his 1981 Nuclear Policy Statement. Today, the author proposes to briefly summarize some of the significant achievements concerning implementation of the NWPA, and to direct your attention to courses of action they have placed before the States and Indian Tribes for comment and about which they will formally seek Congressional direction

  10. Liquid wastes processing device

    International Nuclear Information System (INIS)

    Purpose: To enable safety and easy evaporation of liquid components in contaminated radioactive liquid wastes, as well as to recover the cleaned-up vapors by way of distillation into liquid components. Constitution: After supplying neutralized radioactive liquid wastes into an evaporator, a vertical moving rack is adjusted so as to suck the contaminated airs in a glove box. The liquid wastes are evaporated by a heater and the vapors are cleaned up in an inclined filter element. Further, the cleaned up vapors are formed into liquid in a water cooled cooling cylinder and then introduced to a gas phase separation and liquid collection device. While on the other hand, gases are sent from a gas outlet through a vent pipe to a suction pump and discharged therefrom into a simple glove box. (Horiuchi, T.)

  11. Waste management. Sector 6

    International Nuclear Information System (INIS)

    The waste management section of this report deals with two sectors: land disposal of solid waste and wastewater treatment. It provides background information on the type of emissions that contribute to the greenhouse gases from these two sectors, presents both sector current status in Lebanon, describes the methodology followed to estimate the corresponding emissions, and presents the results obtained regarding greenhouse emissions. The total methane emissions from solid waste disposal on land are 42.804 Gg approximately. There are no emissions from wastewater and industrial handling systems because, for the target year 1994, there was no treatment facilities in Lebanon. The wastewater (municipal, commercial and industrial) was directly discharged into the sea, rivers, ravines or septic tanks which indicate that methane or nitrous oxide emissions are significant if not nonexistent. Note that this situation will change in the future as treatment plants are being constructed around the country and are expected to come into operation by the year 2000

  12. Managing nuclear waste

    International Nuclear Information System (INIS)

    The Nuclear Waste Policy Acts (NWPA) of 1982 provide a plan for the nation's first permanent repository for spent reactor fuel. The legislation authorizes DOE to plan and build the first permanent geologic repository for commercial nuclear waste in the US by 1998. The entire $20 billion-plus cost will fall to the ratepayers of those electric utilities that own and operate nuclear power plants. An interview with James B. Hall, Program Manager of the Utility Nuclear Waste Management Group (UNWMG) explores problems with having the law codify geologic disposal technology and with DOE mission plans. Hall describes the site selection process, the likely public protest over safety and financing, UNWMG cooperation and interaction with DOE on the project, and technological needs. 2 figures

  13. Inconsistent pathways of household waste

    International Nuclear Information System (INIS)

    The aim of this study was to provide policy-makers and waste management planners with information about how recycling programs affect the quantities of specific materials recycled and disposed of. Two questions were addressed: which factors influence household waste generation and pathways? and how reliable are official waste data? Household waste flows were studied in 35 Swedish municipalities, and a wide variation in the amount of waste per capita was observed. When evaluating the effect of different waste collection policies, it was found to be important to identify site-specific factors influencing waste generation. Eleven municipal variables were investigated in an attempt to explain the variation. The amount of household waste per resident was higher in populous municipalities and when net commuting was positive. Property-close collection of dry recyclables led to increased delivery of sorted metal, plastic and paper packaging. No difference was seen in the amount of separated recyclables per capita when weight-based billing for the collection of residual waste was applied, but the amount of residual waste was lower. Sixteen sources of error in official waste statistics were identified and the results of the study emphasize the importance of reliable waste generation and composition data to underpin waste management policies.

  14. DOE Waste Treatability Group Guidance

    Energy Technology Data Exchange (ETDEWEB)

    Kirkpatrick, T.D.

    1995-01-01

    This guidance presents a method and definitions for aggregating U.S. Department of Energy (DOE) waste into streams and treatability groups based on characteristic parameters that influence waste management technology needs. Adaptable to all DOE waste types (i.e., radioactive waste, hazardous waste, mixed waste, sanitary waste), the guidance establishes categories and definitions that reflect variations within the radiological, matrix (e.g., bulk physical/chemical form), and regulated contaminant characteristics of DOE waste. Beginning at the waste container level, the guidance presents a logical approach to implementing the characteristic parameter categories as part of the basis for defining waste streams and as the sole basis for assigning streams to treatability groups. Implementation of this guidance at each DOE site will facilitate the development of technically defined, site-specific waste stream data sets to support waste management planning and reporting activities. Consistent implementation at all of the sites will enable aggregation of the site-specific waste stream data sets into comparable national data sets to support these activities at a DOE complex-wide level.

    Recurring waste management noncompliance problems have spurred a fundamental site-wide process revision to characterize and disposition wastes at the Idaho National Engineering and Environmental Laboratory. The reengineered method, termed Waste Generator Services, will streamline the waste acceptance process and provide waste generators comprehensive waste management services through a single, accountable organization to manage and disposition wastes in a timely, cost-effective, and compliant manner. This report outlines the strategy for implementing Waste Generator Services across the INEEL. It documents the culmination of efforts worked by the LMITCO Environmental Management Compliance Reengineering project team since October 1997. These efforts have included defining problems associated with the INEEL waste management process; identifying commercial best management practices; completing a review of DOE Complex-wide waste management training requirements; and involving others through an Integrated Process Team approach to provide recommendations on process flow, funding/charging mechanisms, and WGS organization. The report defines the work that will be performed by Waste Generator Services, the organization and resources, the waste acceptance process flow, the funding approach, methods for measuring performance, and the implementation schedule and approach. Field deployment will occur first at the Idaho Chemical Processing Plant in June 1998. Beginning in Fiscal Year 1999, Waste Generator Services will be deployed at the other major INEEL facilities in a phased approach, with implementation completed by March 1999.

  18. Practical approaches toward waste minimization

    International Nuclear Information System (INIS)

    In the last decade, hazardous waste management has become a national concern. As more and more contamination is attributed to past hazardous waste handling and disposal practices, government and industry are fuming toward alternative methods of dealing with hazardous waste. Clearly, traditional disposal methods will not solve the problem. For hazardous waste managers, proper management of their company's or client's waste has become increasingly complex, expensive and demanding. Companies are struggling to keep up and comply with emerging regulations. Land disposal costs are increasing, as are the restrictions for the types of acceptable waste for disposal. Alternative treatment technologies are difficult to permit and are often too expensive for small-quantity generators. Liability for hazardous waste practices has become a frightening issue, with cleanup costs ranging into the millions of dollars. Public image has become a growing concern for many companies, with public input and risk communication playing increasingly important roles in the hazardous waste arena. These problems of waste management are not easily solved. Many strategies are available for dealing with hazardous wastes, including waste minimization. To put waste minimization into perspective, the following section compares the advantages and disadvantages of different waste management strategies

  1. Swedish nuclear waste efforts

    International Nuclear Information System (INIS)

    After the introduction of a law prohibiting the start-up of any new nuclear power plant until the utility had shown that the waste produced by the plant could be taken care of in an absolutely safe way, the Swedish nuclear utilities in December 1976 embarked on the Nuclear Fuel Safety Project, which in November 1977 presented a first report, Handling of Spent Nuclear Fuel and Final Storage of Vitrified Waste (KBS-I), and in November 1978 a second report, Handling and Final Storage of Unreprocessed Spent Nuclear Fuel (KBS II). These summary reports were supported by 120 technical reports prepared by 450 experts. The project engaged 70 private and governmental institutions at a total cost of US $15 million. The KBS-I and KBS-II reports are summarized in this document, as are also continued waste research efforts carried out by KBS, SKBF, PRAV, ASEA and other Swedish organizations. The KBS reports describe all steps (except reprocessing) in handling chain from removal from a reactor of spent fuel elements until their radioactive waste products are finally disposed of, in canisters, in an underground granite depository. The KBS concept relies on engineered multibarrier systems in combination with final storage in thoroughly investigated stable geologic formations. This report also briefly describes other activities carried out by the nuclear industry, namely, the construction of a central storage facility for spent fuel elements (to be in operation by 1985), a repository for reactor waste (to be in operation by 1988), and an intermediate storage facility for vitrified high-level waste (to be in operation by 1990). The R and D activities are updated to September 1981

  2. Calculation of projected waste loads for transuranic waste management alternatives

    International Nuclear Information System (INIS)

    The level of treatment and the treatment and interim storage site configurations (decentralized, regional, or centralized) impact transuranic (TRU) waste loads at and en route to sites in the US Department of Energy (DOE) complex. Other elements that impact waste loads are the volume and characteristics of the waste and the unit operation parameters of the technologies used to treat it. Projected annual complexwide TRU waste loads under various TRU waste management alternatives were calculated using the WASTEunderscoreMGMT computational model. WASTEunderscoreMGMT accepts as input three types of data: (1) the waste stream inventory volume, mass, and contaminant characteristics by generating site and waste stream category; (2) unit operation parameters of treatment technologies; and (3) waste management alternative definitions. Results indicate that the designed capacity of the Waste Isolation Pilot Plant, identified under all waste management alternatives as the permanent disposal facility for DOE-generated TRU waste, is sufficient for the projected complexwide TRU waste load under any of the alternatives

  5. Automatic radioactive waste recycling

    International Nuclear Information System (INIS)

    The production of a plutonium ingot by calcium reduction process at CEA/Valduc generates a residue called 'slag'. This article introduces the recycling unit which is dedicated to the treatment of slags. The aim is to separate and to recycle the plutonium trapped in this bulk on the one hand, and to generate a disposable waste from the slag on the other hand. After a general introduction of the facilities, some elements will be enlightened, particularly the dissolution step, the filtration and the drying equipment. Reflections upon technological constraints will be proposed, and the benefits of a fully automatic recycling unit of nuclear waste will also be stressed. (authors)

  6. Low level radioactive waste

    International Nuclear Information System (INIS)

    More than 10 new disposal facilities for low level radioactive waste are now under development in the USA. They were planned in the wake of the highly visible failures of three such sites and a widespread loss of public confidence, both in shallow burial technology and the federal government's ability to regulate commercial waste disposal enterprises. The development of new technology and active involvement of state governments presents the nuclear power industry with its best opportunity for regaining the public confidence that it lost during the 1970s. This paper critically explores the fundamental technical, economic, political and value issues at stake in this process. (author)

  7. Radioactive wastes in Oklo

    International Nuclear Information System (INIS)

    The acceptance of the Nuclear Energy as electric power supply implies to give answer to the population on the two main challenges to conquer in the public opinion: the nuclear accidents and the radioactive wastes. Several of the questions that are made on the radioactive wastes, its are the mobility migration of them, the geologic stability of the place where its are deposited and the possible migration toward the aquifer mantels. Since the half lives of the radioactive waste of a Nuclear Reactor are of several hundred of thousands of years, the technical explanations to the previous questions little convince to the public in general. In this work summary the results of the radioactive waste generated in a natural reactor, denominated Oklo effect that took place in Gabon, Africa, it makes several thousands of millions of years, a lot before the man appeared in the Earth. The identification of at least 17 reactors in Oklo it was carried out thanks to the difference in the concentrations of Uranium 235 and 238 prospective, and to the analysis of the non-mobility of the radioactive waste in the site. It was able by this way to determine that the reactors with sizes of hardly some decimeter and powers of around 100 kilowatts were operating in intermittent and spontaneous form for space of 150,000 years, with operation cycles of around 30 minutes. Recent studies have contributed information valuable on the natural confinement of the radioactive waste of the Oklo reactors in matrixes of minerals of aluminum phosphate that caught and immobilized them for thousands of millions of years. This extracted information from the nature contributes guides and it allows 'to verify' the validity of the current proposals on the immobilization of radioactive wastes of a nuclear reactor. This work presents in clear and accessible form to the public in general on the secure 'design', operation, 'decommissioning' and 'storage' of the radioactive waste of the reactors that the nature put

  8. Radioactive waste processing method

    International Nuclear Information System (INIS)

    When granular materials comprising radioactive wastes containing phosphorus are processed at first in a fluidized bed type furnace, if the granular materials are phosphorus-containing activated carbon, granular materials comprising alkali compound such as calcium hydroxide and barium hydroxide are used as fluidizing media. Even granular materials of slow burning speed can be burnt stably in a fluidizing state by high temperature heat of the fluidizing media, thereby enabling to take a long burning processing time. Accordingly, radioactive activated carbon wastes can be processed by burning treatment. (T.M.)

  13. Nuclear waste - perception and reality

    International Nuclear Information System (INIS)

    The author addresses the perceptual gap between the general public's attitude to nuclear waste disposal and British Nuclear Fuel Limited's (BNFL) effort to convey the measures actually being taken and the scale of the problem. It is a matter of real concern to BNFL that as much as 80% of the British population believe there is no safe way to dispose of nuclear waste. By comparing the volumes of low-intermediate -and high-level radioactive wastes produced annually to those for industrial waste in general, the nuclear waste issue is shown to represent only a very small fraction of the national toxic waste issue. The building of specific plants for high-and low-level waste disposal is described as is a public relations programme undertaken in 1990 to improve awareness and factual information available about BNFL's commitment to safe waste disposal. The campaign targeted the West Cumbrian region and BNFL employees and has proved successful. U.K

  15. Method of processing liquid wastes

    International Nuclear Information System (INIS)

    Purpose: To improve the safety of processing liquid wastes by enriching the radioactive liquid wastes to higher than the concentration becoming solid at cooling time. Method: Radioactive liquid wastes containing sodium sulfate as main ingredient are enriched so the concentration of the sodium sulfate becomes 40 to 60%, a container is filled with the concentrated liquid wastes and allowed to stand for solidification, and can then be stored. Solidified wastes are heated and molted after radioactive nuclide is attenuated, and are then solidified in a stable solidifier such as cement, asphalt, plastic, glass, or the lide. Accordingly, since the radioactive liquid wastes are not handled as powder, equipment is not contaminated with powder, and it renders unnecessary the immediate solidification of wastes high radiation wastes with concrete, can avoid the decrease in the strength of a solidifiers such as plastics, and so can eventually enhance the safety of the final processing.

  12. Regulation of radioactive waste management

    International Nuclear Information System (INIS)

    This bulletin contains information about activities of the Nuclear Regulatory Authority of the Slovak Republic (UJD). In this leaflet the regulation of radioactive waste management of the UJD are presented. Radioactive waste (RAW) is the gaseous, liquid or solid material that contains or is contaminated with radionuclides at concentrations or activities greater than clearance levels and for which no use is foreseen. The classification of radioactive waste on the basis of type and activity level is: - transition waste; - short lived low and intermediate level waste (LlLW-SL); - long lived low and intermediate level waste (LlLW-LL); - high level waste. Waste management (in accordance with Act 130/98 Coll.) involves collection, sorting, treatment, conditioning, transport and disposal of radioactive waste originated by nuclear facilities and conditioning, transport to repository and disposal of other radioactive waste (originated during medical, research and industrial use of radioactive sources). The final goal of radioactive waste management is RAW isolation using a system of engineered and natural barriers to protect population and environment. Nuclear Regulatory Authority of the Slovak Republic regulates radioactive waste management in accordance with Act 130/98 Coll. Inspectors regularly inspect and evaluate how the requirements for nuclear safety at nuclear facilities are fulfilled. On the basis of safety documentation evaluation, UJD issued permission for operation of four radioactive waste management facilities. Nuclear facility 'Technologies for treatment and conditioning contains bituminization plants and Bohunice conditioning centre with sorting, fragmentation, evaporation, incineration, supercompaction and cementation. Final product is waste package (Fibre reinforced container with solidified waste) acceptable for near surface repository in Mochovce.

  13. Mixed Waste Working Group report

    Energy Technology Data Exchange (ETDEWEB)

    1993-11-09

    The treatment of mixed waste remains one of this country`s most vexing environmental problems. Mixed waste is the combination of radioactive waste and hazardous waste, as defined by the Resource Conservation and Recovery Act (RCRA). The Department of Energy (DOE), as the country`s largest mixed waste generator, responsible for 95 percent of the Nation`s mixed waste volume, is now required to address a strict set of milestones under the Federal Facility Compliance Act of 1992. DOE`s earlier failure to adequately address the storage and treatment issues associated with mixed waste has led to a significant backlog of temporarily stored waste, significant quantities of buried waste, limited permanent disposal options, and inadequate treatment solutions. Between May and November of 1993, the Mixed Waste Working Group brought together stakeholders from around the Nation. Scientists, citizens, entrepreneurs, and bureaucrats convened in a series of forums to chart a course for accelerated testing of innovative mixed waste technologies. For the first time, a wide range of stakeholders were asked to examine new technologies that, if given the chance to be tested and evaluated, offer the prospect for better, safer, cheaper, and faster solutions to the mixed waste problem. In a matter of months, the Working Group has managed to bridge a gap between science and perception, engineer and citizen, and has developed a shared program for testing new technologies.

  19. Glasses for nuclear waste immobilization

    International Nuclear Information System (INIS)

    Vitrification of nuclear wastes is attractive because of its flexibility, the large number of elements which can be incorporated in the glass, its high corrosion durability and the reduced volume of the resulting waste form. Vitrification is a mature technology and has been used for high level nuclear waste (HLW) immobilisation for more than 40 years in France, Germany and Belgium, Russia, UK, Japan and the USA. Vitrification involves melting of waste materials with glass-forming additives so that the final vitreous product incorporates the waste contaminants in its macro- and micro-structure. Hazardous waste constituents are immobilised either by direct incorporation into the glass structure or by encapsulation when the final glassy material can be in form of a glass composite material (GCM). Both borosilicate and phosphate glasses are currently used to immobilise nuclear wastes, moreover in addition to relatively homogeneous glasses novel GCM are used to immobilise problematic waste streams. The spectrum of wastes which are currently vitrified increases from HLW to low and intermediate wastes (LILW) such as legacy wastes in Hanford, USA and nuclear power plant operational wastes in Russia and Korea.

  8. Liquid waste processing device

    International Nuclear Information System (INIS)

    In a liquid waste processing device for processing living water wastes discharged from nuclear power plant facilities through a filtration vessel and a sampling vessel, a filtration layer disposed in the filtration vessel is divided into a plurality of layers along planes vertical to the direction of flow and the size of the filter material for each of the divided layers is made finer toward the downstream. Further, the thickness of the filtration material in each of the divided layers is also reduced toward the downstream. The filter material is packed such that the porosity in each of the divided layers is substantially identical. Further, the filtration material is packed in a mesh-like bag partitioned into a desired size and laid with no gaps to the planes vertical to the direction of the flow. Thus, liquid wastes such as living water wastes can be processed easily and simply so as to satisfy circumstantial criteria without giving undesired effects on the separation performance and life time and with easy replacement of filter.

  15. Radioactive waste management

    International Nuclear Information System (INIS)

    The OECD Nuclear Energy Agency (NEA) attaches considerable importance to its cooperation with Japan. It was said in the annual conference in 1977 that the presentation of the acceptable policy regarding radioactive waste management is the largest single factor for gaining public confidence when nuclear power is adopted with assurance. The risk connected with radioactive wastes was often presented as the major obstacle to the development of nuclear energy, however, an overall impression of optimism and confidence prevailed by the technical appraisal of the situation in this field by the committee of the NEA. This evolution can be easily explained by the significant progress achieved in radioactive waste management both at the technical level and with respect to the implementation of special legislation and the establishment of specialized institutions and financing schemes. More research will focus on the optimization of the technical, safety and economic aspects of specific engineering designs at specific sites on the long term isolation of wastes, and the NEA contributes to this general effort. The implementation of disposal programs is also in progress. (Kako, I.)

The mission of the WIPP is to demonstrate the safe, environmentally sound disposal of transuranic (TRU) waste resulting from the nation's defense program activities. Authorized by Congress in 1979 via Public Law 96-164, the WIPP represents a necessary, environmentally responsible, deep geologic disposal option. Initially thought to be subject to regulation under the Atomic Energy Act, further definition of the 1980 Resource Conservation and Recovery Act (RCRA) in 1986 and 1988 has made it clear that this demonstration must also show compliance with RCRA. The majority of retrievable TRU waste proposed and available for eventual disposal at the WIPP also contains hazardous constituents defined by RCRA, with the resultant mixed waste subject to its provisions

    2013-04-01

    Indium, selenium, tellurium, gallium, molybdenum, cadmium and silicon are some of the major elements used in photovoltaic cells. Fully aware of the limited availability of these metals in future, recycling has been recognized as the most advisable end-of-life strategy to save these raw materials from turning into production wastes. On the other hand, statutory measures such as 'Kreislaufwirtschaftsgesetz' (the German law encouraging closed-loop economy) aim to achieve a maximum quota of recycling and a minimum use of resources such as energy and raw materials. By the year of 2050, end-of-life photovoltaic panels are anticipated to amount to 9.57 million tons. Although we are not there yet, discussions on recycling have already started. We have to prepare for higher waste volumes expected in the coming years. But already today we need to solve some environmental problems like loss of conventional resources (e.g., glass) and rare metals. All of the known approaches for recycling photovoltaic semiconductor material seem economically and environmentally inefficient. In this paper, we report about reclaiming metals from scrap of thin film systems and associated photovoltaic manufacturing wastes like sandblasting dust and overspray. We also report one universal wet-chemical treatment for reclaiming the metals from CIS, CIGS or CdTe photovoltaic waste. Further, we discuss the application of our method to new PV systems, such as substrates other than glass (stainless steel, aluminum or plastic foil sheets) and alternative semiconductor alloys such as GaAs.

  2. Mixed waste analysis

    International Nuclear Information System (INIS)

    Improved superpower relations followed by the Soviet Union's collapse acted as catalysts for changing the mission at Rocky Flats. Now, environmental concerns command as much attention as production capability. As a result, laboratory instruments once dedicated to plutonium production have a new purpose - the analysis of mixed wastes. Waste drums destined for WIPP require headspace analysis by GS/MS (gas chromatography/mass spectrometry) for volatile and semi-volatile organic compounds (VOC and SVOC). Flame AA analysis provides information on inorganic constituents. EPA guidelines for waste analysis (SW-846) overlook the obstacles of glove box manipulations. Sometimes, SW-846 guidelines conflict with the Rocky Flats waste minimization effort. However, the EPA encourages SW-846 adaptations if experimental data confirms the results. For water and soil samples, AA analysis of laboratory control samples show method capability inside a glove box. Non-radioactive drum headspace samples use a revised version of USEPA compendium method TO-14. Radioactive drum headspace samples require new instrumentation and change to SW-846 methods

    Industrial and technological developments have increased rapidly throughout the world including Turkey. Furthermore, the population of Turkey is also increasing and the ever-increasing consumption creates larger amounts of waste materials and adversely affects the environment and human health. The development of a waste management and disposal system has become necessary in all countries of the world. As part of the process of seeking entry to the European Union, Turkey continues to prepare the necessary legislation to satisfy European Union regulations for the disposal of solid waste, packaging waste, biodegradable waste and medical waste materials within the framework of the strategy. An integrated waste management system is necessary for each town in Turkey that is suitable for the different contents and increasing amounts of waste produced. In the present study, Turkey's geographical regions were examined in terms of population and the total amount of solid waste generated in each province to produce detailed data for the Turkish Ministry of Environment and Forestry. As a result of this study, it is understood that Turkey has drawn up a 'road map' which will be followed by the 2008-2012 Waste Management Action Plan. To achieve this, the Ministry of the Environment and Forestry, Turkey and the municipalities must fulfill the tasks that have been allocated to them. Turkey will attain the European Union standards for waste management if these tasks lead to the achievement of the targets within the action plan. PMID:20686052

  5. Low-level waste management - suggested solutions for problem wastes

    International Nuclear Information System (INIS)

    Problem wastes are those wastes which are difficult or require unusual expense to place into a waste form acceptable under the requirements of 10 CFR 61 or the disposal site operators. Brookhaven National Laboratory has been investigating the use of various solidification agents as part of the DOE Low-Level Waste Management Program for several years. Two of the leading problem wastes are ion exchange resins and organic liquids. Ion exchange resins can be solidified in Portland cement up to about 25 wt % resin, but waste forms loaded to this degree exhibit significantly reduced compressive strength and may disintegrate when immersed in water. Ion exchange resins can also be incorporated into organic agents. Mound Laboratory has been investigating the use of a joule-heated glass melter as a means of disposing of ion exchange resins and organic liquids in addition to other combustible wastes

    Danish nanoproduct inventory (www.nanodb.dk) to get a general understanding of the fate of ENM during waste management in the European context. This was done by: 1. assigning individual products to an appropriate waste material fraction, 2. identifying the ENM in each fraction, 3. comparing identified...... waste fractions with waste treatment statistics for Europe, and 4. illustrating the general distribution of ENM into incineration, recycling and landfilling. Our results indicate that ╲plastic from used product containers╡ is the most abundant and diverse waste fraction, comprising a variety of both...... nanoproducts and materials. While differences are seen between individual EU countries/regions according to the local waste management system, results show that all waste treatment options are significantly involved in nanowaste handling, suggesting that research activities should cover different areas.

  7. Electrochemical incineration of wastes

    1990-08-01

    The novel technology of waste removal in space vehicles by electrochemical methods is presented to convert wastes into chemicals that can be eventually recycled. The important consideration for waste oxidation is to select a right kind of electrode (anode) material that should be stable under anodic conditions and also a poor electrocatalyst for oxygen and chlorine evolution. On the basis of long term electrolysis experiments on seven different electrodes and on the basis of total organic carbon reduced, two best electrodes were identified. The effect of redox ions on the electrolyte was studied. Though most of the experiments were done in mixtures of urine and waste, the experiments with redox couples involved 2.5 M sulfuric acid in order to avoid the precipitation of redox ions by urea. Two methods for long term electrolysis of waste were investigated: (1) the oxidation on Pt and lead dioxide electrodes using the galvanostatic methods; and (2) potentiostatic method on other electrodes. The advantage of the first method is the faster rate of oxidation. The chlorine evolution in the second method is ten times less then in the first. The accomplished research has shown that urine/feces mixtures can be oxidized to carbon dioxide and water, but current densities are low and must be improved. The perovskite and Ti4O7 coated with RuO2 are the best electrode materials found. Recent experiment with the redox agent improves the current density, however, sulphuric acid is required to keep the redox agent in solution to enhance oxidation effectively. It is desirable to reduce the use of acid and/or find substitutes.

  8. Fukushima remediation waste management

    International Nuclear Information System (INIS)

    The regional contamination from radiation released from Fukushima Dai-ichi has decreased considerably since the accident - due to radioactive decay and the natural self-cleaning of environmental systems. Despite the generally low health hazard involved, there has been great investment in developing and testing technology for remediation. This will then be implemented in a phased manner, with the aim of allowing evacuated communities to return as quickly as possible. Although the clean-up involves mainly low technology to wash surfaces and remove contaminated materials, efforts are taken to reduce the costs, the time required and, in particular, the volume of waste produced. Induced, waste management is a major concern: the present concept of initial temporary storage at individual locations for maximum of 3 hears followed by a maximum of 30 years of centralise interim interim storage is a costly, non-optimised option. The concept for final disposal following interim storage has yet to be established. The potential for reduction of waste volumes and implementing conditioning / packaging in a manner that will facilitate storage and eventual disposal is discussed. This is put in context of the bigger challenges associated with on-site clean-up and decommissioning and the potential for developing a holistic approach to management of radioactive waste. Here, a key advantage is the extensive knowledge base supporting geological disposal in Japan, which can be selectively mined to produce efficient and cost-effective solutions to these waste management challenges. Further, an existing user-friendly, web-based, communication platform ('CoolRep') can be modified to serve the critical role of informing stakeholders and involving them in key decisions in this highly sensitive topic.

  9. Krsko NPP radioactive waste characteristics

    International Nuclear Information System (INIS)

    In May 2005 Krsko NPP initiated the Radioactive Waste Characterization Project and commissioned its realization to the consulting company Enconet International, Zagreb. The Agency for Radwaste Management was invited to participate on the Project. The Project was successfully closed out in August 2006. The main Project goal consisted of systematization the existing and gathering the missing radiological, chemical, physical, mechanical, thermal and biological information and data on radioactive waste. In a general perspective, the Project may also be considered as a part of broader scope of activities to support state efforts to find a disposal solution for radioactive waste in Slovenia. The operational low and intermediate level radioactive waste has been structured into 6 waste streams that contain evaporator concentrates and tank sludges, spent ion resins, spent filters, compressible and non-compressible waste as well as specific waste. For each of mentioned waste streams, process schemes have been developed including raw waste, treatment and conditioning technologies, waste forms, containers and waste packages. In the paper the main results of the Characterization Project will be briefly described. The results will indicate that there are 17 different types of raw waste that have been processed by applying 9 treatment/conditioning technologies. By this way 18 different waste forms have been produced and stored into 3 types of containers. Within each type of container several combinations should be distinguished. Considering all of this, there are 34 different types of waste packages altogether that are currently stored in the Solid Radwaste Storage Facility at the Krsko NPP site. Because of these findings a new identification system has been recommended and consequently the improvement of the existing database on radioactive waste has been proposed. The potential areas of further in depth characterization are indicated. In the paper a brief description on the

  10. Hanford Tank Waste - Near Source Treatment of Low Activity Waste

    International Nuclear Information System (INIS)

    Abstract only. Treatment and disposition of Hanford Site waste as currently planned consists of 100+ waste retrievals, waste delivery through up to 8+ miles of dedicated, in-ground piping, centralized mixing and blending operations- all leading to pre-treatment combination and separation processes followed by vitrification at the Hanford Tank Waste Treatment and Immobilization Plant (WTP). The sequential nature of Tank Farm and WTP operations requires nominally 15-20 years of continuous operations before all waste can be retrieved from many Single Shell Tanks (SSTs). Also, the infrastructure necessary to mobilize and deliver the waste requires significant investment beyond that required for the WTP. Treating waste as closely as possible to individual tanks or groups- as allowed by the waste characteristics- is being investigated to determine the potential to 1) defer, reduce, and/or eliminate infrastructure requirements, and 2) significantly mitigate project risk by reducing the potential and impact of single point failures. The inventory of Hanford waste slated for processing and disposition as LAW is currently managed as high-level waste (HLW), i.e., the separation of fission products and other radionuclides has not commenced. A significant inventory of this waste (over 20M gallons) is in the form of precipitated saltcake maintained in single shell tanks, many of which are identified as potential leaking tanks. Retrieval and transport (as a liquid) must be staged within the waste feed delivery capability established by site infrastructure and WTP. Near Source treatment, if employed, would provide for the separation and stabilization processing necessary for waste located in remote farms (wherein most of the leaking tanks reside) significantly earlier than currently projected. Near Source treatment is intended to address the currently accepted site risk and also provides means to mitigate future issues likely to be faced over the coming decades. This paper

  11. Waste acceptance and waste loading for vitrified Oak Ridge tank waste

    International Nuclear Information System (INIS)

    The Office of Science and Technology of the DOE has funded a joint project between the Oak Ridge National Laboratory (ORNL) and the Savannah River Technology Center (SRTC) to evaluate vitrification and grouting for the immobilization of sludge from ORNL tank farms. The radioactive waste is from the Gunite and Associated Tanks (GAAT), the Melton Valley Storage Tanks (MVST), the Bethel Valley Evaporator Service Tanks (BVEST), and the Old Hydrofractgure Tanks (OHF). Glass formulation development for sludge from these tanks is discussed in an accompanying article for this conference (Andrews and Workman). The sludges contain transuranic radionuclides at levels which will make the glass waste form (at reasonable waste loadings) TRU. Therefore, one of the objectives for this project was to ensure that the vitrified waste form could be disposed of at the Waste Isolation Pilot Plant (WIPP). In order to accomplish this, the waste form must meet the WIPP Waste Acceptance Criteria (WAC). An alternate pathway is to send the glass waste forms for disposal at the Nevada Test Site (NTS). A sludge waste loading in the feed of 6 wt percent will lead to a waste form which is non-TRU and could potentially be disposed of at NTS. The waste forms would then have to meet the requirements of the NTS WAC. This paper presents SRTC''s efforts at demonstrating that the glass waste form produced as a result of vitrification of ORNL sludge will meet all the criteria of the WIPP WAC or NTS WAC

  12. Regulation on radioactive waste management

    International Nuclear Information System (INIS)

    A national calculator control system for the metropolitan radioactive waste banks was developed in 1999. The NNSA reviewed by the regulations the feasibility of some rectification projects for uranium ore decommissioning and conducted field inspections on waste treating systems and radioactive waste banks at the 821 plant. The NNSA realized in 1999 the calculator control for the disposal sites of low and medium radioactive waste. 3 routine inspections were organized on the reinforced concrete structures for disposal units and their pouring of concrete at waste disposal site and specific requirements were put forth

    Title: Food Waste in the UK Written by: David Magrane and Silje Biørnstad Background According to the ‘UK Love Food Hate Waste’ approximately 7 million tonnes of food and drinks from homes in the United Kingdom are wasted every year, whereas more than half of the food wasted is still perfectly fine to eat or drink. This is what made us write a project about food waste in the UK. We wanted to look into the perspective of consumer waste. This lead us to the following research question...

  14. Tank waste concentration mechanism study

    International Nuclear Information System (INIS)

    This study determines whether the existing 242-A Evaporator should continue to be used to concentrate the Hanford Site radioactive liquid tank wastes or be replaced by an alternative waste concentration process. Using the same philosophy, the study also determines what the waste concentration mechanism should be for the future TWRS program. Excess water from liquid DST waste should be removed to reduce the volume of waste feed for pretreatment, immobilization, and to free up storage capacity in existing tanks to support interim stabilization of SSTS, terminal cleanout of excess facilities, and other site remediation activities

  15. Nuclear waste management in Canada

    International Nuclear Information System (INIS)

    The classification of radioactive wastes in Canada involves two categories - waste of such a nature or in such amounts that it could be hazardous to the public, and waste which can be dealt with safely by methods available to individual institutions having at their disposal only conventional methods for getting rid of unwanted material. It is easy to provide for long-term retention of radioactive wastes if no account need be taken of expense. However, it is unreasonable (and discouraging to progress) to insist upon techniques of waste management that are applicable to multi-curie sources when the amounts to be dealt with are in the millicurie range.

  16. Solidification of radioactive liquid wastes

    International Nuclear Information System (INIS)

    Purpose: To decrease the amount of surface active agents required for solidifying sodium sulfate-containing concentrated radioactive liquid wastes with asphalts. Method: Water soluble calcium compounds (calcium nitrate, etc.) are added to alkaline radioactive concentrated liquid wastes essentially consisting of sodium sulfate to adjust the pH value of the liquid wastes to 4.5 - 8.5. The addition amount of the water soluble calcium compounds (based on the weight of the calcium ions) is set to about 2 - 5% of the sulfate ions in the liquid wastes. Then, surface active agents are added by 3 - 10 weight % to the solid contents in the liquid wastes. (Ikeda, J.)

  17. Method of packaging radioactive wastes

    International Nuclear Information System (INIS)

    Purpose: To decrease the leaching of radioactive waste in marine environment. Method: Fillers are placed between a drum can and an inner cage for charging radioactive wastes in order to prevent the leakage of the radioactive wastes from the drum can. Leaching inhibitors for radioactive materials are mixed with the fillers made of organic substance such as asphalts and plastics. The leaching inhibitors are made of materials in the similar chemical form to that of the radioactive materials in the wastes and mixed into the fillers to the saturation limit of dissolution. For the radioactive wastes containing spent adsorbents for iodine, the inhibitors are made of silver nitrates. (Ikeda, J.)

  18. Radioactive waste: Issues and debates

    International Nuclear Information System (INIS)

    Waste management in general has always been in terms of regulation Environmental, a subject of attention but also voltages. Radioactive waste management is no exception to the rule and concentrates, sometimes irrationally, the vast majority industry fears nuclear. The first difficulty is to define radioactive waste, which raises further questions with regard to the case law on this topic and reactions of stakeholders. One of the other components of the debate on radioactive waste is the ability of different actors to ensure sustainable waste management Radioactive in optimum conditions in terms of nuclear safety.This results in the acceptance management solutions by the public.

  1. Nuclear waste: the political realities

    International Nuclear Information System (INIS)

    The land dumping of nuclear waste has again come to the attention of anti-nuclear groups, environmentalists and the media, following the announcement of the proposed sites for intermediate-level nuclear waste at Billingham and Bedford. Opposition has already surfaced on a large scale, with public meetings in both areas and a revitalisation of the waste dumping network. This article explains some of the political realities in the nuclear debate, and suggests how we can tackle the issue of waste dumping, remembering that, even if the industry closes tomorrow, there are vast quantities of waste which must be safely and democratically dealt with.

    Energy generation by wastes is considered one method of waste management that has the benefit of energy recovery. From the waste-to-energy point of view, waste cooking oil, waste lubricating oil, and waste plastics have been considered good candidates for feedstocks for energy conversion due to their high heating values. Compared to the independent management of these three wastes, the idea of co-processing them in integration is expected to gain more benefit. The economies of scale and the synergy of co-processing these wastes results in higher quality and higher yield of the end products. In this study, we use cost-benefit analysis to evaluate the integrated management scenario of collecting the three wastes and converting them to energy. We report the total heat of combustion of pyrolytic oil at the maximum and minimum conversion rates, and conduct a sensitivity analysis in which the parameters of an increase of the electricity cost for operating the process and increase of the feedstock transportation cost are tested. We evaluate the effects of economy of scale in the case of integrated waste management. We compare four cases of waste-to-energy conversion with the business as usual (BAU) scenario, and our results show that the integrated co-processing of waste cooking oil, waste lubricating oil, and waste plastics is the most profitable from the viewpoints of energy yield and economics.

    International Nuclear Information System (INIS)

    All of the countries over the world have their own policies about how waste were managed. Malaysia as one of the developing country also faces this problems. So, the government was established Department of National Solid Waste Management under Ministry of Housing and Local Government to control and make sure all of these problem on waste will managed systematically. Guiding principle on these issues was mentioned in 3rd Outline Perspective Plan (2000 until 2010), National Policy on Solid Waste Management, National Strategic Plan on Solid Waste Management and also 10th Malaysian Plan. In 10th Malaysian Plan, the government will complete restructuring efforts in this Solid Waste Management sector with the federalization of solid waste management and public cleansing and full enforcement of the Solid Waste and Public Cleansing Management Act 2007. The key outcomes of these efforts will include providing support to local authorities, delivering comprehensive and sanitary services and ensuring that waste is managed in a sustainable manner. These presentations cover all aspect of solid waste management in Malaysia. What are guiding principle, paradigm shift, strategies approach, monitoring and enforcement and also mention about some issues and constraint that appear in Solid waste management in Malaysia.

  7. Radioactive wastes on Kazakhstan territory

    International Nuclear Information System (INIS)

    Common amount of radioactive wastes in Kazakhstan makes up 235 million tons. In Semipalatinsk test site in the result of surface and underground explosions low-radioactive wastes have accumulated in the form of soils contaminated with radionuclides and these wastes could be buried during re-cultivation works. In the same time there are places contaminated with plutonium. These soils should be buried in special points. Volume of these wastes is estimated in 5,000 m3. In Kazakhstan there are one power nuclear reactor in Aktau, 3 research reactors on Semipalatinsk site territory and 1 in Almaty city. During operation of BN-350 power reactor in Aktau city till present day 10,000 m3 of different wastes have been accumulated. Great amount of wastes will appear in 2005 during the reactor decommissioning, common volume of processed and packaged wastes after BN-350 reactor out of operation will be estimated in 623,000 m3. In Kazakhstan system of gathering, processing, and transporting of radioactive wastes is not taken into operation yet. According of conception on radioactive wastes burial and IAEA recommendation part of wastes with volume 67,450 m3 (intermediate- and high-level radioactive wastes) are subjected to burial in points in geological formations

    2000-08-11

    The Building 772-F Far-Field Transuranic (TRU) Waste Counting System is used to measure the radionuclide content of waste packages produced at the Central Laboratory Facilities (CLAB). Data from the instrument are entered into an Excel spreadsheet. The spreadsheet calculates the necessary information required for completion of the Transuranic Waste Characterization Form (OSR 29-90) including the weight percent of the various waste components. In addition, the spreadsheet calculates the associated Low Level Waste (LLW) stream information that potentially could be useful if the waste container is ever downgraded from TRU to LLW. The spreadsheet also has the capability to sum activities from source material added to a waste container after assay. A validation data set for the spreadsheet along with the appropriate results are also presented in this report for spreadsheet verification prior to each use.

    Full Text Available In this paper the origin and properties of radioactive waste as well as its classification scheme (low-level waste – LLW, intermediate-level waste – ILW, high-level waste – HLW are presented. The various options for conditioning of waste of different levels of radioactivity are reviewed. The composition, radiotoxicity and reprocessing of spent fuel and their effect on storage and options for final disposal are discussed. The current situation of final waste disposal in a selected number of countries is mentioned. Also, the role of the International Atomic Energy Agency with regard to the development and monitoring of international safety standards for both spent nuclear fuel and radioactive waste management is described.

  11. Commercial nuclear-waste management

    International Nuclear Information System (INIS)

    This report is primarily concerned with nuclear waste generated by commercial power operations. It is clear, however, that the total generation of commercial nuclear waste does not tell the whole story, there are sizeable stockpiles of defense nuclear wastes which will impact areas such as total nuclide exposure to the biosphere and the overall economics of waste disposal. The effects of these other nuclear waste streams can be factored in as exogenous inputs. Their generation is essentially independent of nuclear power operations. The objective of this report is to assess the real-world problems associated with nuclear waste management and to design the analytical framework, as appropriate, for handling nuclear waste management issues in the International Nuclear Model. As such, some issues that are not inherently quantifiable, such as the development of environmental Impact Statements to satisfy the National Environmental Protection Act requirements, are only briefly mentioned, if at all

  12. Waste minimization handbook, Volume 1

    International Nuclear Information System (INIS)

    This technical guide presents various methods used by industry to minimize low-level radioactive waste (LLW) generated during decommissioning and decontamination (D and D) activities. Such activities generate significant amounts of LLW during their operations. Waste minimization refers to any measure, procedure, or technique that reduces the amount of waste generated during a specific operation or project. Preventive waste minimization techniques implemented when a project is initiated can significantly reduce waste. Techniques implemented during decontamination activities reduce the cost of decommissioning. The application of waste minimization techniques is not limited to D and D activities; it is also useful during any phase of a facility's life cycle. This compendium will be supplemented with a second volume of abstracts of hundreds of papers related to minimizing low-level nuclear waste. This second volume is expected to be released in late 1996

  13. Selected transuranic waste immobilization systems

    International Nuclear Information System (INIS)

    Waste contaminated with transuranic (TRU) elements may require immobilization prior to final disposal. Pacific Northwest Laboratory has conducted research and development to identify and characterize the wastes; to evaluate the possible immobilization requirements and treatment alternatives; and to develop immobilization process technologies. This paper describes systems that are anticipated to be capable of immobilizing a selected TRU waste stream consisting of a blend of process sludge and incinerator ash. The selected waste streams are based on the waste compositions generated at the Rocky Flats Plant, Golden, Colorado. The specific waste forms and processes considered are identified in Table 1. Summary results of leach testing of the immobilized waste forms is provided for comparison. This information along with the processing considerations identify the major advantages and disadvantages of each system. The evaluation of these considerations suggests the implementation for cement or glass system with preference to the cast cement system because of its process simplicity

  15. Biological denitrification of nitrate wastes

    International Nuclear Information System (INIS)

    Enriched uranium wastes are purified in the Y-12 Plant, and the uranium product is recycled. One purification method involves dissolving the waste in nitric acid followed by solvent extraction to recover uranium. The process generates nitrate waste solutions which must be discarded. For many years, these wastes were stored in unlined ponds. In 1976 a recycle process was installed, and about half of the wastes were recovered and reused. A biological process (stirred tank) was installed, and the remaining nitrate wastes were biologically decomposed to produce nitrogen gas. Some additional nitrate wastes, generated in other parts of the plant, continued to be placed in the open ponds which must now be decommissioned. In 1983 an in-situ biological process was developed and tested whereby the open ponds were successfully biologically treated. This paper describes the results of the stirred tank and the in-situ pond treatment processes used in the plant to decompose nitrate ions

  16. Product control of radioactive waste

    International Nuclear Information System (INIS)

    The aim of the seminar was to give a survey of product quality control and to find out whether the producers/conditioners of waste set and fulfil requirements for the quality of the waste. The program included the following main areas: Random sample tests; Container tests; Process qualification and inspection, and Inspections of waste from fuel element reprocessing abroad. In other lectures, there are reports on measures for producers of waste for guaranteeing the final storage requirements, on quality assurance measurements in the conditioning of waste from large research establishments and from fuel element manufacture. The calling up of waste containers and the documentation of waste data is also introduced. (orig./HP)

  17. Nuclear waste vs. democracy

    International Nuclear Information System (INIS)

    In the United States the storage and disposal of high-level nuclear waste is a highly contentious issue because under current plans the public is subjected to unaccepted, involuntary risks. The proposed federal policy includes the forced siting of a repository and interim storage facilities in Nevada, and the transport of waste across the entire nation through large cities and within 2 mile of over 50 million people. At its destination in Nevada, the residents would face coexistence with a facility housing highly radioactive wastes that remain dangerous for many thousands of years. Scientific predictions about the performance and safety of these facilities is highly uncertain and the people foresee possibly catastrophic threats to their health, safety and economic well-being for generations to come. The public sees this currently proposed plan as one that seeks to maximise the profits of the commercial nuclear industry through imposing risk and sacrifice to communities who reap no benefit. And there is no evidence that this plan is actually a solution to the problem. The American public has never had the opportunity to participate in the nuclear waste debate and government plans are presented to people as being necessary and inevitable. To allow democracy into the decisions could be costly to the nuclear industry and it might thwart the government program, but that is the nature of democracy. If the utilities are established to provide a public service, and the government is founded on the principle of public representation, then the nuclear waste debate must conform to those requirements. What we see in this case is a continuing change of rule and law to accommodate a corporate power and the subrogation of national principle. The result of this situation has been that the public exercises its only option - which is obstructing the federal plan. Because the odds are so heavily stacked in favour of government and industry and average citizens have so little access

  18. Re-defining the concepts of waste and waste management:evolving the Theory of Waste Management

    OpenAIRE

    Pongrácz, E. (Eva)

    2002-01-01

    Abstract In an attempt to construct a new agenda for waste management, this thesis explores the importance of the definition of waste and its impact on waste management, and the role of ownership in waste management. It is recognised that present legal waste definitions are ambiguous and do not really give an insight into the concept of waste. Moreover, despite its explicit wish of waste prevention, when according to present legislation a thing is assigned the label...

  19. Radioactive waste management at ANSTO - Managing current and historic waste

    International Nuclear Information System (INIS)

    The Australian Nuclear Science and Technology Organisation (ANSTO) carries out nuclear research and development at Lucas Heights about 40 km southeast of Sydney, Australia. The 10 MW heavy water research reactor (HIFAR) has operated at Lucas Heights site for over 40 years with associated radioisotope and radiopharmaceutical production facilities and a wide range of nuclear science and technology R and D is carried out. Most of the radioactive waste generated by these activities is stored at the site. Following a review of ANSTO's waste management facilities and practices in 1996, an integrated five-year Waste Management Action Plan (WMAP) was established to address legacy issues and ensure that ANSTO waste management met international standards. Topics undertaken under the Waste Management Action Plan (WMAP) included construction and operation of improved storage facilities for low-level solid radioactive waste, better monitoring of storage facilities for spent research reactor fuel and intermediate level liquid wastes, development of processes to convert liquid and solid wastes into forms more suitable for long term storage and disposal, improved characterisation of wastes and development of a database for radioactive waste.

  20. Radioactive waste processing field

    International Nuclear Information System (INIS)

    Storing space for radioactive wastes (storage tunnels) are formed underground of the sea bottom along coast. A plurality of boreholes through which sea water flows are pored vertically in a direction intersecting underground streams of brine in the ground between the tunnels and seaside. Sea water introduction pipes are joined to the upper side walls of the boreholes. The sea water introduction pipes have introduction ports protruded under the sea level of the coastal sea area region. Since sea water flows from the introduction ports to the boreholes passing through the sea water introduction pipes, sea water is always filled in the boreholes. Therefore, brine is sufficiently supplied toward the land by sea water from the boreholes, the underground stream of brine is negligibly small. This can prevent radioactive contamination due to flow of the underground water when radioactive wastes are buried in the underground near coast. (I.N.)

  1. Radioactive waste: show time?

    International Nuclear Information System (INIS)

    The basic concept within both EC funded SAPIERR I and SAPIERR II projects (FP6) is that of one or more geological repositories developed in collaboration by two or more European countries to accept spent nuclear fuel, vitrified high-level waste and other long-lived radioactive waste from those partner countries. The SAPIERR II project (Strategic Action Plan for Implementation of Regional European Repositories) examines in detail issues that directly influence the practicability and acceptability of such facilities. This paper describes the work in the SAPIERR II project (2006-2008) on the development of a possible practical implementation strategy for shared, regional repositories in Europe and lays out the first steps in implementing that strategy.

    1995-01-01

    A containment and waste package system for processing and shipping tritium xide waste received from a process gas includes an outer drum and an inner drum containing a disposable molecular sieve bed (DMSB) seated within outer drum. The DMSB includes an inlet diffuser assembly, an outlet diffuser assembly, and a hydrogen catalytic recombiner. The DMSB absorbs tritium oxide from the process gas and converts it to a solid form so that the tritium is contained during shipment to a disposal site. The DMSB is filled with type 4A molecular sieve pellets capable of adsorbing up to 1000 curies of tritium. The recombiner contains a sufficient amount of catalyst to cause any hydrogen add oxygen present in the process gas to recombine to form water vapor, which is then adsorbed onto the DMSB.

  4. Offshore waste treatment guidelines

    International Nuclear Information System (INIS)

    These guidelines were prepared to aid offshore oil and gas operators in the management of waste materials related to petroleum drilling and production operations in offshore areas regulated by the Canada-Newfoundland and Labrador Offshore Petroleum Board (CNLOPB) and the Canada-Nova Scotia Offshore Petroleum Board (CNSOPB). A description of the relevant sections of the regulatory regime applicable to Canada's offshore oil and gas operations was included. Offshore operators are expected to take all reasonable measures to minimize the volumes of waste materials generated by their operations. The guidelines included recommendations for identifying, monitoring, and reporting discharges; performance expectations for specific discharges; requirements for greenhouse gas (GHG) and other air emissions; methods of characterizing and monitoring produced water, drilling muds, and desalination brine. Operational discharges associated with the installation and maintenance of subsea systems were also reviewed, and qualifications of analytical laboratories were presented. 24 refs., 2 appendices.

  5. Abundance, Excess, Waste

    Directory of Open Access Journals (Sweden)

    Rox De Luca

    2016-02-01

    Her recent work focuses on the concepts of abundance, excess and waste. These concerns translate directly into vibrant and colourful garlands that she constructs from discarded plastics collected on Bondi Beach where she lives. The process of collecting is fastidious, as is the process of sorting and grading the plastics by colour and size. This initial gathering and sorting process is followed by threading the components onto strings of wire. When completed, these assemblages stand in stark contrast to the ease of disposability associated with the materials that arrive on the shoreline as evidence of our collective human neglect and destruction of the environment around us. The contrast is heightened by the fact that the constructed garlands embody the paradoxical beauty of our plastic waste byproducts, while also evoking the ways by which those byproducts similarly accumulate in randomly assorted patterns across the oceans and beaches of the planet.

  6. Nuclear waste vault sealing

    International Nuclear Information System (INIS)

    A nuclear waste vault must be designed and built to ensure adequate isolation of the nuclear wastes from human contact. Consequently, after a vault has been fully loaded, it must be adequately sealed off to prevent radionuclide migration which may be provided by circulating groundwater. Vault sealing entails four major aspects, i.e.: (a) vault grouting; (b) borehole sealing; (c) buffer packing; and (d) backfilling. Of particular concern in vault sealing are the physical and chemical properties of the sealing material, its long-term durability and stability, and the techniques used for its emplacement. Present sealing technology and sealing materials are reviewed in terms of the particular needs of vault sealing. Areas requiring research and development are indicated

  9. Whither nuclear waste disposal?

    International Nuclear Information System (INIS)

    With respect to the argument that geologic disposal has failed, I do not believe that the evidence is yet sufficient to support that conclusion. It is certainly true that the repository program is not progressing as hoped when the Nuclear Waste Policy Act of 1982 established a 1998 deadline for initial operation of the first repository. The Department of Energy (DOE) now expects the repository to be available by 2010, and tat date depends upon a finding that the Yucca Mountain site - the only site that DOE is allowed by law to evaluate - is in fact suitable for use. Furthermore, scientific evaluation of the site to determine its suitability is stopped pending resolution of two lawsuits. However, I believe it is premature to conclude that the legal obstacles are insuperable, since DOE just won the first of the two lawsuits, and chances are good it will win the second. The concept of geologic disposal is still broadly supported. A recent report by the Board on Radioactive Waste Management of the National Research Council noted that 'There is a worldwide scientific consensus that deep geological disposal, the approach being followed in the United States, is the best option for disposing of high-level radioactive waste'. The U.S. Nuclear Regulatory Commission (USNRC) recently implicitly endorsed this view in adopting an updated Waste Confidence position that found confidence that a repository could be available in the first quarter of the next century - sufficient time to allow for rejection of Yucca Mountain and evaluation of a new site

  10. Hanford Defined Wastes model

    International Nuclear Information System (INIS)

    This paper describes the methodology behind the Hanford Defined Wastes (HDW) model for estimating the contents of Hanford high level waste (HLW) tanks. The HDW model is based on historical process and transaction histories for each tank and has four major components: Waste Status and Transaction Record Summary (WSTRS), Tank Layer Model (TLM), Supernatant Mixing Model (SMM), and HDW Compositions. Three examples of the application of HDW model estimates are described, including comparisons with global site inventories, comparisons with per tank assays, and comparisons of HDW TOC (Total Organic Carbon) estimates with existing hydrogen watch list tanks. The HDW model provides a cross check on existing assumptions for the global site inventory of wastes. Note that existing inventories for Hanford are based on much the same source information as the HDW model, chemicals used and process flowsheet data. Despite that, the HDW model predicts that the sodium inventory for Hanford tanks is 40,300 MT (metric tonnes), which is only 58% of the previous baseline estimate of 69,000 MT. There are other significant differences for inventories of chromium, iron, and nitrate as well. There are two causes for these differences; (1) previous neglect of chemical inventory placed into the ground at Hanford; (2) double counting attributed to tank inventory that was retrieved, reprocessed, and returned to the tanks. This double-counted inventory was counted once when it first went into the tanks and then again after it was reprocessed. The HDW model estimates also can provide a basis for targeting tanks for organic safety issues. In particular, the HDW model has shown that 88% of flammable gas watch list tanks have HDW estimated organic concentrations in excess of 0.64 wt% TOC. Derivation of variabilities for the HDW model estimates and other potential uses will also be outlined

    Perhaps 80 percent of papermaking energy is expended in chemical pulping of vegetable cellulose, a natural polymer. Commercial supplies of wood, bagasse, cotton and flax are valued as renewable resources and bio-mass assets; however, few enterprises will salvage waste-paper and cardboard from their trash. A basic experiment in the Materials Lab uses simple equipment to make crude handsheets. Students learn to classify secondary fibers, identify contraries, and estimate earnings.

  13. Underground nuclear waste containments

    International Nuclear Information System (INIS)

    In the United States, about a hundred million gallons of high-level nuclear waste are stored in underground containments. Basically, these containments are of two different designs: single-shell and double-shell structures. The single-shell structures consist of reinforced concrete cylindrical walls seated on circular mats and enclosed on top with torispherical domes or circular flat roofs. The walls and the basemats are lined with carbon steel. The double-shell structures provide another layer of protection and constitute a completely enclosed steel containment within the single-shell structure leaving an annular space between the two walls. Single-shell containments are of earlier vintage and were built in the period 1945-1965. Double-shell structures were built through the 1960s and 1970s. Experience gained in building and operating the single-shell containments was used in enhancing the design and construction of the double-shell structures. Currently, there are about 250 underground single-shell and double-shell structures containing the high-level waste with an inventory of about 800 million curies. During their service lives, especially in early stages, these structures were subjected to thermal excursions of varying extents; also, they have aged in the chemical environment. Furthermore, in their remaining service lives, the structures may be subjected to loads for which they were not designed, such as larger earthquakes or chemical explosions. As a result, the demonstration of safety of these underground nuclear containments poses a challenge to structural engineers, which increases with time. Regardless of current plans for gradual retrieval of the waste and subsequent solidification for disposal, many of these structures are expected to continue to contain the waste through the next 20-40 years. In order to verify their structural capabilities in fulfilling this mission, several studies were recently performed at Brookhaven National Laboratory

    The potential use of chemically modified mango waste is investigated in this article. Observations suggest that mango seed and peel are important raw materials for a number of industrial applications:- confectionery and chocolate industries, soft drink manufacturers, food processing, and textile and paper industries. Studies indicate that a high quality mango pectin can be obtained from mango peel. The wide availability, ease of collection and storage, will facilitate the establishment of small and medium size industries near mango processing plants. (Refs. 14).

    Not much effort needed, just willpower In order to keep the cost of disposing of waste materials as low as possible, CERN provides two types of recipient at the entrance to each building: a green plastic one for paper/cardboard and a metal one for general refuse. For some time now we have noticed, to our great regret, a growing negligence as far as selective sorting is concerned, with, for example, the green recipients being filled with a mixture of cardboard boxes full of polystyrene or protective wrappers, plastic bottles, empty yogurts pots, etc. …We have been able to ascertain, after careful checking, that this haphazard mixing of waste cannot be attributed to the cleaning staff but rather to members of the personnel who unscrupulously throw away their rubbish in a completely random manner. Non-sorted waste entails heavy costs for CERN. For information, once a non-compliant item is found in a green recipient, the entire contents are sent off for incineration rather than recycling… We are all concerned...

  20. Waste processing method

    International Nuclear Information System (INIS)

    X-rays are irradiated from a predetermined direction to solid wastes containing radioactive isotopes packed in a bag before charged into an inlet of an incinerator. Most of the wastes is burnable plastics such as test tubes and papers. Glasses such as chemical bottles and metals such as lead plates for radiation shielding are contained as a portion of the wastes. The X-rays have such an intensity capable of discriminating metals and glasses from burnable materials. Irradiation images formed on a X-ray irradiation receiving portion are processed, and the total number of picture elements on the portion where a gradation of the light receiving portion of the metal is within a predetermined range is counted on the image. Then, the bag having total picture elements of not less than a predetermined number are separated from the bag having a lesser number. Similar processings are conducted for glasses. With such procedures, the bags containing lead and glasses not suitable to incineration are separated from the bags not containing them thereby enabling to prevent lowering of operation efficiency of the incinerator.

  1. Attitudes to nuclear waste

    International Nuclear Information System (INIS)

    This is a study of risk perception and attitudes with regard to nuclear waste. Two data sets are reported. In the first set, data were obtained from a survey of the general population, using an extensive questionnaire. The second set constituted a follow-up 7 years later, with a limited number of questions. The data showed that people considered the topic of nuclear waste risks to be very important and that they were not convinced that the technological problems had been solved. Experts associated with government agencies were moderately trusted, while those employed by the nuclear industry were much distrusted by some respondents, and very much trusted by others. Moral obligations to future generations were stressed. A large portion (more than 50 per cent) of the variances in risk perception could be explained by attitude to nuclear power, general risk sensitivity and trust in expertise. Most background variables, except gender, had little influence on risk perception and attitudes. The follow-up study showed that the attitude to nuclear power had become more positive over time, but that people still doubted that the problems of nuclear waste disposal had been solved. 49 refs

  2. Synthesizing optimal waste blends

    International Nuclear Information System (INIS)

    Vitrification of tank wastes to form glass is a technique that will be used for the disposal of high-level waste at Hanford. Process and storage economics show that minimizing the total number of glass logs produced is the key to keeping cost as low as possible. The amount of glass produced can be reduced by blending of the wastes. The optimal way to combine the tanks to minimize the vole of glass can be determined from a discrete blend calculation. However, this problem results in a combinatorial explosion as the number of tanks increases. Moreover, the property constraints make this problem highly nonconvex where many algorithms get trapped in local minima. In this paper the authors examine the use of different combinatorial optimization approaches to solve this problem. A two-stage approach using a combination of simulated annealing and nonlinear programming (NLP) is developed. The results of different methods such as the heuristics approach based on human knowledge and judgment, the mixed integer nonlinear programming (MINLP) approach with GAMS, and branch and bound with lower bound derived from the structure of the given blending problem are compared with this coupled simulated annealing and NLP approach

  3. Management of radioactive wastes

    International Nuclear Information System (INIS)

    The law from December 30, 1991, precisely defines 3 axes of researches for the management of high level and long-lived radioactive wastes: separation/transmutation, surface storage and underground disposal. A global evaluation report about these researches is to be supplied in 2006 by the French government to the Parliament. A first synthesis of the knowledge gained after 14 years of research has led the national commission of the public debate (CNDP) to organize a national debate about the general options of management of high-level and long-lived radioactive wastes before the 2006 date line. The debate comprises 4 public hearings (September 2005: Bar-le-Duc, Saint-Dizier, Pont-du-Gard, Cherbourg), 12 round-tables (October and November 2005: Paris, Joinville, Caen, Nancy, Marseille), a synthesis meeting (December 2005, Dunkerque) and a closing meeting (January 2006, Lyon). This document is the synthesis of the round table debates which took place at Joinville, i.e. in the same area as the Bure underground laboratory of Meuse/Haute-Marne. Therefore, the discussion focuses more on the local impacts of the setting up of a waste disposal facility (environmental aspects, employment, economic development). (J.S.)

  4. Radioactive waste management glossary

    International Nuclear Information System (INIS)

    Terminology used in documents published by the IAEA is frequently defined in glossaries in the separate documents so that understanding is enhanced, particularly for terms having unique meanings in the field of radioactive waste management. This has been found to be a good practice but frequently a burdensome one, too. In addition, terms in various documents occasionally were used differently. Thus, a common glossary of terms for radioactive waste management documents is believed to have merit. This glossary has been developed for use in IAEA documentation on radioactive waste management topics. The individual items have been compiled by selecting terms and definitions from thirty sources, listed on the next page, and numerous people. An effort has been made to use the definitions in internationally-accepted glossaries (e.g. ICRP, ICRU, ISO), with minimum modification; similarly, definitions in recently published IAEA documents have been respected. Nevertheless, when modifications were believed appropriate, they have been made. The glossary, stored on magnetic tape, is intended to be used as a standard for terminology for IAEA use; it is hoped that some benefits of common international terminology may result from its use in IAEA documentation

  5. Waste incineration. Final report

    Energy Technology Data Exchange (ETDEWEB)

    Egede Rasmussen, Anja

    2004-06-15

    This prepatory thesis is a literature study on the incineration of waste. It deals with the concepts of municipal solid waste, the composition and combustion of it. A main focus is on the European emission regulations and the formation of dioxins, as well as a big effort is put into the treatment of solid residues from municipal solid waste incineration. In the latter area, concepts of treatment, such as physical and chemical separations, solidification and stabilization techniques, thermal methods, and extraction methods have been discussed. Evaluation of possible methods of treatment has been done, but no conclusions made of which is the best. Though, indications exist that especially two methods have shown positive qualities and must be further investigated. These methods are the acid extraction and sulfide stabilization (AES) process and the phosphate stabilization method of WES-PHix. Economic potentials of the two methods have been evaluated, and with the information obtained, it seems that the price for treatment and later landfilling of a material with improved leaching characteristics, will be approximately the same as the presently most used solution of export to Norway. However, more tests, investigations and economic evaluations are necessary in order for support of the findings in this work. (au)

  6. Nuclear waste materials

    International Nuclear Information System (INIS)

    Ion beam techniques were very helpful to gain a better understanding of the behaviour of waste matrices, both glasses and ceramics, under conditions of aqueous corrosion (leaching) and radiation damage. Due to the ease of varying dose, dose rate, energy and type of damaging ions, and due to the powerful nature of ion beam techniques for nondestructive analyses of complex surface layers, ion beams were frequently and successfully applied to matrices for safe long-time storage of radioactive waste. Rutherford-backscattering, elastic recoil detection and reactions with high energy N-beams helped to better understand the chemistry of leaching, to detect enrichment and depletion of glass components and waste at the leached surfaces and to follow synergistic effects in leaching in the near-field of the final repository, hence in the presence of e.g. rock salt and container materials. Radiation effects were simulated with ion beams and interesting results were obtained, in particular on mechanical behaviour of damaged glasses and ceramics, their fracture behaviour etc

  7. Waste - a burning issue

    International Nuclear Information System (INIS)

    Modern municipal waste incineration technology which incorporates energy recovery is being promoted as environmentally friendly. As such, it qualifies for subsidies when used by electric utilities as part of the United Kingdom Government's Non Fossil Fuel Obligation for electricity generation. It is argued, however, that this is a misuse of money intended to promote renewable energy sources. Incineration is primarily a waste disposal technology and an inefficient means for producing electricity. The environmental benefits claimed for incineration are that it reduces the volume of landfill, particularly plastics, that the ash residues are easier to handle than the original waste, that the methane production and smells from landfill are avoided, that transport costs are reduced and that energy reclaim offsets costs. Arguments to set against these benefits are presented. Incinerators are expensive to construct and beyond the construction phase offer little economic spin-off for the host community. The landfill reduction is not as great as claimed and the fly-ash from incinerators includes heavy metals in the form of metal chlorides which can be leached out instead of being chemically bound into the original plastic matrix. Dioxin pollution from incineration is still a significant concern. Overall more energy could be obtained by a programme of recycling and composting. (1 figure, 9 references) (UK)

  8. Energy from wastes and the private waste contracting industry

    International Nuclear Information System (INIS)

    The focus of this ongoing work is the utilisation of general non hazardous industrial and commercial waste as an energy or fuel source. Whereas much of the existing experience in energy from waste (EFW) is related to municipal solid wastes (MSW), there is very little direct experience with these other waste streams and the shortage of reliable information in this field is notoriously lacking. It is important to have a good understanding of the private waste contracting industry (pwci) in order to establish the conditions under which energy from waste technologies may play an economically and technically feasible role within that industry's development. The Non Fossil Fuel Obligation (NFFO) has encouraged entrepreneurial interest through premium payments for electricity generated from renewable sources. (author)

    This research project deals with: Analysis and characterization of mine waste piles or tailings impoundment abandoned in mining areas; Survey of mining environmental pollution from mine waste impounds; Modelling of pollutants in groundwater around tailings impoundment; Demonstration of acid rock drainage from coal mine waste rock piles and experiment of seeding on waste rock surface; Development of a liner using tailings. Most of mine wastes are deposited on natural ground without artificial liners and capping for preventing contamination of groundwater around mine waste piles or containments. In case of some mine waste piles or containments, pollutants have been released to the environment, and several constituents in drainage exceed the limit of discharge from landfill site. Metals found in drainage exist in exchangeable fraction in waste rock and tailings. This means that if when it rains to mine waste containments, mine wastes can be pollutant to the environment by release of acidity and metals. As a result of simulation for hydraulic potentials and groundwater flow paths within the tailings, the simulated travel paths correlated well with the observed contaminant distribution. The plum disperse, both longitudinal and transverse dimensions, with time. Therefore liner system is a very important component in tailings containment system. As experimental results of liner development using tailings, tailings mixed with some portion of resin or cement may be used for liner because tailings with some additives have a very low hydraulic conductivity.

  10. Municipal waste - management and treatment

    International Nuclear Information System (INIS)

    Though per capita waste generation in Nepalese urban cities is not so high, the lack of proper waste management is considered one of the severe problems to be faced by urban people in future. With rapid urbanization, life style of people is changing their habits and consuming more materials and producing a large volume of waste in urban areas in Nepal. The nature and amount of waste generated in municipality is dependent of demography and geography. But most common aspect of municipal waste in Nepal is more than 60% of the waste biodegradable. Whatever the nature and amount of waste generated, the most common practice of managing municipal waste is to dispose in the riverside nearby or dumped elsewhere. The involvement of private sector in waste management is a new concept adopted by many municipalities in Nepal. One of the most progress approaches, 4R (reduces, reuse, recycle and refuse) principle is being practiced. The need of awareness progressive like segregation of wastes at collection point also being practiced in Nepal. Finally, Proper formulation of program and legislation and its application is one of the major challenges for local authorities in Nepal. (author)

  11. Mercury separation from aqueous wastes

    International Nuclear Information System (INIS)

    This project is providing an assessment of new sorbents for removing mercury from wastes at US Department of Energy sites. Four aqueous wastes were chosen for lab-scale testing; a high-salt, acidic waste currently stored at Idaho National Engineering Laboratory (INEL); a high-salt, alkaline waste stored at the Savannah River Site (SRS); a dilute lithium hydroxide solution stored at the Oak Ridge Y-12 Plant; and a low-salt, neutral groundwater generated at the Y-12 Plant. Eight adsorbents have been identified for testing, covering a wide range of cost and capability. Screening tests have been completed, which identified the most promising adsorbents for each waste stream. Batch isotherm tests have been completed using the most promising adsorbents, and column tests are in progress. Because of the wide range of waste compositions tested, no one adsorbent is effective in all of these waste streams. Based on loading capacity and compatibility with the waste solutions. the most effective adsorbents identified to date are SuperLig 618 for the INEL tank waste stimulant; Mersorb followed by lonac SR-3 for the SRS tank waste stimulant; Durasil 70 and Ionac SR-3) for the LIOH solution; and lonac SR-3 followed by lonac SR-4 and Mersorb for the Y-12 groundwater

  12. Environmental restoration and waste management

    International Nuclear Information System (INIS)

    The purpose of this Five-Year Plan is to establish an agenda for compliance and cleanup against which progress will be measured. DOE is committed to an open and participatory process for developing a national priority system for expenditure of funds. This system will be based on scientific principles and risk reduction in terms that are understandable to the public. The Plan will be revised annually, with a five-year planning horizon. For FY 1991--1995, this Plan encompasses total program activities and costs for DOE Corrective Activities, Environmental Restoration, Waste Management Operations, and Applied R ampersand D. It addresses hazardous wastes, radioactive wastes, mixed wastes (radioactive and hazardous), and sanitary wastes. It also addresses facilities and sites contaminated with or used in the management of those wastes. The Plan does not include the Safety and Health Program (Office of the Assistant Secretary for Environment, Safety, and Health) or programs of the Office of Civilian Radioactive Waste Management. It does include the annual Defense Programs contribution to the Nuclear Waste Fund for disposal of defense high-level waste and research toward characterizing the defense waste form for repository disposal

  13. Concrete waste reduction of 50%

    International Nuclear Information System (INIS)

    During decommissioning quite a volume of concrete waste is produced. The degree of activation of the waste can range from clearly activated material to slightly activated or contaminated concrete. The degree of activation influences the applicable waste management processes that can be applied. The subsequent waste management processes can be identified for concrete waste are; disposal, segregation, re-use, conditional release and release. With each of these steps, the footprint of radioactive decommissioning waste is reduced. Future developments for concrete waste reduction can be achieved by applying smart materials in new build facilities (i.e. fast decaying materials). NRG (Nuclear Research and consultancy Group) has investigated distinctive waste management processes to reduce the foot-print of concrete waste streams resulting from decommissioning. We have investigated which processes can be applied in the Netherlands, both under current legislation and with small changes in legislation. We have also investigated the separation process in more detail. Pilot tests with a newly patented process have been started in 2015. We expect that our separation methods will reduce the footprint reduction of concrete waste by approximately 50% due to release or re-use in the nuclear sector or in the conventional industry.

  14. Energy from Municipal Waste Program

    Science.gov (United States)

    1992-05-01

    Each year Americans throw away 3 quads of energy in the form of municipal waste and pay 6 billion dollars for the privilege. Only about 21 percent of our municipal wastes are used productively to generate electricity or produce new products by recycling. In 1990, waste-to-energy (WTE) plants and recycling efforts contributed roughly half a quad of energy in the form of electricity and reduced energy use. This productive use of waste avoided the disposal of about 50 million tons of wastes to landfills in that year. The Administration National Energy Strategy (NES) estimates that with proper Federal, State, local, and private action the electric generating capacity of WTE facilities could increase 600 percent by 2010 and by over 1200 percent by 2030, compared to 1990 capacity. This would result in about 55 gigawatts (GW) of capacity by 2030, up from roughly 4 GW today. The Department of Energy (DOE) supports an integrated approach to waste management that includes source reduction, WTE, recycling, and landfilling as complementary pieces of a solution to the municipal waste disposal problem. The Energy from Municipal Waste Program, described in this plan, seeks to minimize the productive use of municipal waste as an energy resource to improving its economic and environmental characteristics. While the Program focuses on WTE systems, it is conducted as part of a larger Federal effort that includes source reduction and recycling of wastes to save energy.

  15. Risk management for noncombustion wastes

    International Nuclear Information System (INIS)

    The Noncombustion Waste Risk Management Project is designed to incorporate the insights and information developed in these projects into tools that will help utilities make better noncombustion waste management decisions. Specific project goals are to synthesize information useful to utilities on noncombustion wastes, emphasize waste reduction as a priority over end-of-pipe management, develop methods to manage the costs and risks associated with noncombustion wastes (e.g., direct costs, permitting costs, liability costs, public relations costs), develop software and documentation to deliver the information and analysis methods to the industry. This project was initiated EPRI's Environment Division in late 1988. The early phases of the project involved gathering information on current noncombustion waste management practices, specific utility problems and concerns with respect to these wastes, current and potential future regulations, and current and emerging management options. Recent efforts have focused on characterizing the direct and indirect (e.g., lawsuits, remedial action) costs of managing these wastes and on developing and implementing risk management methods for a subset of wastes. The remainder of this paper describes the specific issues addressed by and the results and insights from the three completed waste-specific studies

  16. The problem of industrial wastes

    International Nuclear Information System (INIS)

    The paper is the result of a feasibility study conducted for the Green peace Office in Lebanon. The overall goal of the study was to work towards implementing a national waste management plan and to combat the import of hazardous wastes from developing countries.The author focuses on the illegal trade of industrial wastes from developed to under developed countries. The trade of toxic wastes causes on environmental pollution. As for Lebanese industries, the main problem is toxic industrial wastes. About 4000 tones/day of domestic wastes are produced in Lebanon. 326000 tones of industrial wastes contain toxic substances are annually produced and wastes growth rate is expected to increase to one million tone/year in 2010. A disaster is threatening Lebanon especially that no policy were taken to deal with the huge growth of wastes. This problem affect on population health especially in the region of Bourj Hammoud. Analysis of ground water in the region of Chekka, confirm the existence of water pollution caused by toxic materials In addition, analysis of Petro coke used in the National Lebanese Cement Industry, contain a high rate of Polycyclic Aromatic Hydrocarbons. Green peace is aware of the danger of wastes in air, water and land pollution and preventing environment of any source of pollution this will certainly lead to a sustainable development of the country

  17. Coal combustion waste management study

    International Nuclear Information System (INIS)

    Coal-fired generation accounted for almost 55 percent of the production of electricity in the United States in 1990. Coal combustion generates high volumes of ash and flue gas desulfurization (FGD) wastes, estimated at almost 90 million tons. The amount of ash and flue gas desulfurization wastes generated by coal-fired power plants is expected to increase as a result of future demand growth, and as more plants comply with Title IV of the 1990 Clean Air Act Amendments. Nationwide, on average, over 30 percent of coal combustion wastes is currently recycled for use in various applications; the remaining percentage is ultimately disposed in waste management units. There are a significant number of on-site and off-site waste management units that are utilized by the electric utility industry to store or dispose of coal combustion waste. Table ES-1 summarizes the number of disposal units and estimates of waste contained at these unites by disposal unit operating status (i.e, operating or retired). Further, ICF Resources estimates that up to 120 new or replacement units may need to be constructed to service existing and new coal capacity by the year 2000. The two primary types of waste management units used by the industry are landfills and surface impoundments. Utility wastes have been exempted by Congress from RCRA Subtitle C hazardous waste regulation since 1980. As a result of this exemption, coal combustion wastes are currently being regulated under Subtitle D of RCRA. As provided under Subtitle D, wastes not classified as hazardous under Subtitle C are subject to State regulation. At the same time Congress developed this exemption, also known as the ''Bevill Exclusion,'' it directed EPA to prepare a report on coal combustion wastes and make recommendations on how they should be managed

  18. Characterization of radioactive hazardous waste

    International Nuclear Information System (INIS)

    The characterization of radioactive hazardous waste, also known as transuranic 'mixed waste' has to be completed before it can be classified for proper treatment (incinerator, mechanical compaction or thermal treatment), packing, and transport. The characterization of the TRU mixed waste is not only complex process but rather an expensive undertaking. The process knowledge is the basic foundation of characterization. It is the documented knowledge of processes and materials that generated the waste. The transuranic waste Quality Assurance Program Plan (QAPP) defines the Data Quality Objectives (DQO's) and provides the scope of analytical parameters and methods required to accurately characterize the radioactive mixed waste. Based on the historical data and process knowledge a sampling and analysis plan can be developed to characterize the radioactive hazardous waste. Based on the characterization, an assessment of the regulatory status can be made before the waste could be accepted for disposal at the WIPP facility. The Waste Acceptance Criteria (WAC) developed by WIPP defines the parameters for receiving and final disposal of the TRU waste. The sets of criteria, such as: heat generated, fissile gram equivalent (FGE), plutonium-equivalent (PE) curies, and specifications of a dose rate have to be met before the waste is accepted for deep geological disposal. The characterization of radioactive waste becomes even more complex due to the presence of iron base metals/alloys, aluminum base metals/alloys, organic, chelating agents that are mixed with plastic, rubber, cellulose, soils and cement. Some of the modern characterization technologies that are under development and currently used for TRU mixed wastes are: nondestructive examination, nondestructive assay, headspace gas analysis, and drum coring for Resources Conservation Recovery Act (RCRA) sampling.

  19. Management of radioactive wastes

    International Nuclear Information System (INIS)

    When I first became concerned with radioactive waste management, in the early 1950's, very little was really known about the subject. There was a general feeling that it was a serious 'problem'. Articles were appearing in the press and talks were being given on the radio suggesting that the wastes generated by the proposed nuclear power reactors might be a serious menace to humanity. The prophets pointed with alarm to the enormous quantities of fission products that would accumulate steadily over the years in tank farms associated with reactor fuel reprocessing plants, and calculations were made of the possible results from rupture of the tanks due to corrosion, earthquakes or enemy attack. Responsible people suggested seriously that the waste disposal problem might be fatal to the development of a nuclear power industry, and this attitude was reinforced by the popular outcry that arose from experience with fallout from nuclear weapons testing. The Canadian nuclear power industry was not critically involved in this controversy because our heavy-water reactors are fuelled with natural uranium, and reprocessing of the fuel is not necessary. The spent fuel contains plutonium, a potential fuel, but the cost of recovering it was such that it was not competitive with natural uranium, which is not in short supply in Canada. Our spent fuel is not dissolved in acid - it is stored. still in its zirconium cladding, under water at the reactor site, or placed in sealed concrete-and-steel pipes below ground. If the price of uranium rises sufficiently it will become profitable to recover the plutonium, and only then shall we have an appreciable amount of waste from this source. However. during the first five or six years of research and development at Chalk River we did investigate fuel processing methods, and like everybody else we grad stainless steel tanks containing high and medium level wastes. These were located quite close to the Ottawa River, and we worried about what

    Minimisation of municipal solid waste and diversion from landfill are necessary for the UK to manage waste sustainably and achieve legislative compliance. A survey of householder attitudes and experiences of a trial for minimising household food waste from waste collection in the county of West Sussex, UK is described. The minimisation method used the Green Cone food digester, designed for garden installation. A postal questionnaire was distributed to 1000 householders who had bought a cone during the trial and a total of 433 responses were received. The main reason for people buying the Green Cone had been concerns about waste (88%), with 78% and 67% of respondents, respectively, claiming to have participated in recycling and home composting in the last 30 days. The waste material most frequently put in the digester was cooked food (91%), followed by fruit waste, vegetable matter and bones/meat. Some respondents were using it for garden and animal waste from pets. Most users found the Green Cone performed satisfactorily. Approximately, 60% of respondents had seen a reduction of 25-50% in the amount of waste they normally put out for collection, with analysis showing reported levels of reduction to be significant (p<0.05). Additional weight surveys by householders recorded an average of 2.7kg/(hweek) diverted to the food digester.

  2. Waste classification system for low-level radioactive wastes

    International Nuclear Information System (INIS)

    In this paper a new method for classifying low-level waste is introduced. The method is based on the geological hazard index introduced by Smith et al. (Smith, C.F.; Cohen, J.J.; McKone, T.E., 1980. A Hazard Index for Underground Toxic Material, UCRL-52889), and provides a measure of the total innate hazard of the waste after disposal. The classification system is designed to be a simple, cost effective and efficient waste screening tool that is conservative and applicable for the great majority of waste streams. The majority of the classification systems methodology has been developed and presented here. Three major tasks still remain to be done. First, values for the persistence of chemicals need to be developed. Second, availability factors must be derived for the ingestion of organic compounds and inhalation of volatile compounds. Third, a thorough review and evaluation of the toxic dose level methodology must be done. The waste classification index has been developed to allow some quantification of total waste hazard. The methodology has been designed to be as general as possible, so that the index would be applicable over a broad range of waste streams. The approach is intuitively simple and conservative. The waste classification index can be very useful as a measurement tool to aid in waste management decisions

  4. Tank waste chemistry: A new understanding of waste aging

    International Nuclear Information System (INIS)

    There is concern about the risk of uncontrolled exothermic reaction(s) in Hanford Site waste tanks containing NO3-/NO2 based salts and/or metal hydroxide sludges in combination with organics or ferrocyanides. However, gradual oxidation of the waste in the tanks to less reactive species appears to have reduced the risk. In addition, wastes sampled to date contain sufficiently large quantities of water so that propagation reactions are highly unlikely. This paper investigates various aspects of the aging of Hanford tank wastes

    Solid wastes are generated in the operation of the installations in France. These solid wastes display different levels of radioactivity. Some of them arising from research centres or reprocessing plants even contain relatively significant quantities of alpha-bearing radionuclides. In order to produce an ultimate waste package that satisfies the requirements set by safety authorities and the organizations in charge of final waste disposal in the concerned countries, solid waste conditioning takes place in a number of successive steps

  6. Radioactive waste shredding: Preliminary evaluation

    International Nuclear Information System (INIS)

    The critical constraints for sizing solid radioactive and mixed wastes for subsequent thermal treatment were identified via a literature review and a survey of shredding equipment vendors. The types and amounts of DOE radioactive wastes that will require treatment to reduce the waste volume, destroy hazardous organics, or immobilize radionuclides and/or hazardous metals were considered. The preliminary steps of waste receipt, inspection, and separation were included because many potential waste treatment technologies have limits on feedstream chemical content, physical composition, and particle size. Most treatment processes and shredding operations require at least some degree of feed material characterization. Preliminary cost estimates show that pretreatment costs per unit of waste can be high and can vary significantly, depending on the processing rate and desired output particle size

  9. Method of removing radioactive waste

    International Nuclear Information System (INIS)

    A paste prepared by mixing a mixed acid containing HF and at least one of HCl and HNO3 with a paste aid is coated at the surface of radioactive wastes, to dissolve the surface thereof. Water is jetted to remove the dissolved radioactive contaminants and the pastes from the surface of the radioactive wastes. Since the pastes are thus used, the amount of liquid wastes can be remarkably reduced compared with that in a conventional electrolysis method. Further, if it is confirmed that dose rate of the radioactive wastes after decontamination is lower than a predetermined level by adding a step of measuring the extent of contamination of the wastes before and after the steps, they can be handled hereinafter being regarded as ordinary wastes.

  14. Waste minimization in analytical methods

    International Nuclear Information System (INIS)

    The US Department of Energy (DOE) will require a large number of waste characterizations over a multi-year period to accomplish the Department's goals in environmental restoration and waste management. Estimates vary, but two million analyses annually are expected. The waste generated by the analytical procedures used for characterizations is a significant source of new DOE waste. Success in reducing the volume of secondary waste and the costs of handling this waste would significantly decrease the overall cost of this DOE program. Selection of appropriate analytical methods depends on the intended use of the resultant data. It is not always necessary to use a high-powered analytical method, typically at higher cost, to obtain data needed to make decisions about waste management. Indeed, for samples taken from some heterogeneous systems, the meaning of high accuracy becomes clouded if the data generated are intended to measure a property of this system. Among the factors to be considered in selecting the analytical method are the lower limit of detection, accuracy, turnaround time, cost, reproducibility (precision), interferences, and simplicity. Occasionally, there must be tradeoffs among these factors to achieve the multiple goals of a characterization program. The purpose of the work described here is to add waste minimization to the list of characteristics to be considered. In this paper the authors present results of modifying analytical methods for waste characterization to reduce both the cost of analysis and volume of secondary wastes. Although tradeoffs may be required to minimize waste while still generating data of acceptable quality for the decision-making process, they have data demonstrating that wastes can be reduced in some cases without sacrificing accuracy or precision
