  • Radioactive waste management technologies used in rehabilitation of radioactively contaminated facilities and areas at the RRC 'Kurchatov Institute' site

    Activities on rehabilitation of eleven temporary radwaste repositories are currently underway at the RRC 'Kurchatov Institute'. Technologies used for exploratory drilling of repositories, their radiation survey, cleaning fill-up soil from the repository ceilings and opening the ceilings, RW extraction, sorting and packing in containers are presented. The radiation situation at the repository site ...

  • Remote control dredge prevents contamination at Fernald, Ohio nuclear remediation site

    When the operations manager at the Fernald, Ohio Super Fund Site Remedial Action Project needed a dredge to remediate sludge from one of four on-site waste (raffinate) pits, they required more than the usual dredging standards. The dredging operation was complicated with the possibility of unknown radon emissions, chemical contamination, and radiation that could be unleashed as material was ...

  • Case study - Low-flow groundwater sampling on a nuclear site

    Nuclear licensed site use of low-flow groundwater sampling shows: Reduced time, reduced quantity of purge water – both thus reducing cost - and reduced risk of operator contact especially with potentially radioactive-contaminated purge water thanks to a self-contained enclosed system. One of the biggest headaches on site is the purge water and the expense of getting rid of it – after ...

  • Radiological Evaluation of contaminated sites and soils VEgAS: an expertise and investigating vehicle

    Summary 1- Fontenay-Aux-Roses CEA Clean-up methodology For the denuclearisation of the first French nuclear research centre (CEA), the centre of Fontenay-aux-Roses started developing in 1999 a clean-up methodology to rehabilitate places that have been contaminated by radioactive materials. The structure of this methodology is comparable to the one that the ...

  • Sitting on a nuclear bombshell

    The images resemble production stills from a cheap Hollywood thriller. Some 125,000 rusty yellow and brown barrels are dumped carelessly into taverns deep below the ground, covered with dirt or salt, and left there to wait out time. The barrels contain nuclear waste, and they are located inside Asse, a research repository for lowand mid-level nuclear waste in Lower Saxony, near Hannover. Here, ...

  • Removal of Radioactive Effluent Waste from Uranium Enrichments Plants

    In an effort to reduce greenhouse emissions many nations and multi-national corporations are once again focusing on the development of safe radioactive sources for energy generation. After a hiatus of some 20 years commercial nuclear power plants are being developed globally to satisfy increasing global energy demands. Whether for generation of electrical power or in the production of fission ...

  • Radioactive waste buried beneath Runit Dome on Enewetak Atoll, Marshall Islands

    In the early 1970s after extensive characterisation of fallout the US Pacific Proving Grounds located at Enewetak Atoll began rehabilitation in preparation for the return of indigenous people who were relocated during the Cold War. Cleanup entailed removal and collection of ∼545 GBq of contaminated topsoil, vegetation, and debris (concrete and metal) that was subsequently entombed within an ...

  • Nuclear Plant in southeastern United States case study

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

  • Counting solutions LSC technical tips from PerkinElmer

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

  • 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 ...

  • Life after barnwell

    Medical facilities that retain dumping privileges at Barnwell, South Carolina’s host site for low-level radioactive waste (LLRW) are breathing sighs of relief, while dozens of former clients from outcast states are still holding their breath. The Federal LLRW Policy Act (1980) limited accesses to Barnwell last year to members of the three-state Atlantic Compact. The act was supposed to foster ...

  • 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 ...

  • 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 ...

  • Is there a reliable and fast deployable system with little human intervention for catastrophic scenarios for immediate and continuous surveillance needed in the Japanese Fukushima disaster?

    Emergency management requires fast mobile AND continuous surveillanceof gamma radiation At nuclear disaster scenarios – like it has just occurred these days in Japan – the efficiency ofemergency management on-site as well as off-site is closely connected to the quality and reliability ofthe recent status information. As one of the essential parameters for assessing the nuclear ...

  • Things to know about the federal government`s nuke dump

    Valentine's Day 2014 was coming to a close. There were fewer than a dozen workers holding down the night shift at the federal government's nuclear waste repository in southern New Mexico. An alarm sounded inside the central monitoring room less than an hour before midnight. Somewhere in the underground salt caverns, radioactivity triggered the ...
