  • Management of spent nuclear fuel and its waste

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

  • Mitsubishi corporation - Spent Potliner (SPL) hazardous waste treatment - Case Study

    The Challenge Spent Potliner (SPL) is generated in the primary production of aluminium and worldwide is estimated to rise at a rate of over 500,000 tonnes per year. The SPL waste contains concentrations of cyanide and fluoride and gives off noxious and flammable gases when in contact with moisture. Unless carefully handled, these contaminants readily "leach" into the surrounding soils and ...

  • Commissioning and operation of high level radioactive waste vitrification and storage facilities: the Indian experience

    In India, R&D work for management of high-level radioactive liquid waste (HLW) was started along with inception of the Indian Atomic Energy Programme. This culminated in the setting up of the first vitrification facility at the Waste Immobilisation Plant (WIP) at Tarapur. The second vitrification facility has been commissioned at WIP at Trombay and the third such facility is being set up at ...

  • Development of the RAW and SNF handling system in the Federal Atomic Energy Agency and in the Russian Federation

    The experience the Russian Federation has gained over the period longer than half a century in handling radioactive wastes (RAW), including their burial in geological formations, is quite unique. These guidelines state the necessity of establishing an integrated state RAW and spent nuclear fuel (SNF) handling system, ensuring safe, effective, efficient, and socially-acceptable development of ...

  • Costing plutonium: economics of reprocessing in India

    The relative merits of reprocessing and direct disposal of spent nuclear fuel have been widely debated in Europe and the USA. An important aspect of the debate has been the economics of reprocessing. So far there have been no studies of the subject in the Indian context. This study assesses the economics of reprocessing in India and the cost of producing plutonium for the fast breeder reactor ...

  • Development of technology for high-level radwaste treatment to ceramic matrix by method of self-propagating high-temperature synthesis

    For the purpose of reduction of the risk of spread of transuranic actinides, carbon-14 and other radionuclides contained in the NPP HLW, the Rosenergoatom concern decided to develop a technology of self-propagating high-temperature synthesis (SHS) to obtain a ceramic matrix suitable for long-term and ecologically safe deep geological disposal of the high-level radwaste of the nuclear industry. ...

  • Properties and Behavior of Radionuclides

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

  • Waste Management Overview

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

  • Soil Flushing

    Introduction In situ soil flushing is the extraction of contaminants from the soil with water or other suitable aqueous solutions. Soil flushing is accomplished by passing the extraction fluid through in-place soils using an injection or infiltration process. Extraction fluids must be recovered from the underlying aquifer and, when possible, they are recycled. Cosolvent Enhancement Cosolvent ...

  • Ionising Radiation

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

  • Soil Vapor Extraction (In Situ)

    Introduction Soil vapor extraction (SVE) is an in situ unsaturated (vadose) zone soil remediation technology in which a vacuum is applied to the soil to induce the controlled flow of air and remove volatile and some semivolatile contaminants from the soil. The gas leaving the soil may be treated to recover or destroy the contaminants, depending on local and state air discharge regulations. ...
