  • 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 ...

  • Heating up natural remediation

    Manjit Kahlon of Provectus Group Ltd describes how it investigated the effect of thermally enhanced soil vapour extraction (TESVE) on indigenous microbial communities and the potential for subsequent biological polishing of chlorinated solvents Field trials were done at the Western Storage Area (WSA) of Harwell in Oxfordshire, a former nuclear research site being decommissioned by Research Sites ...

  • Common sense considerations on nuclear safety today

    Several recent astonishing events at nuclear plants are recalled in this paper. These events are of the type of ‘possible but not credible’ events. The Fukushima tsunami (2011) is the most recent and catastrophic one. A discussion is made on the present (very conservative) safety philosophy and on the reasons why, notwithstanding it, catastrophe (uncontained core melts) may happen at nuclear ...

  • Soils Radiological Characterization under a Nuclear Facility

    Abstract: Nowadays, nuclear industry is facing a crucial need in establishing radiological characterization for the appraisal and the monitoring of any remediation work. Regarding its experience in this domain, the French Atomic Energy Commission (CEA) of Fontenay-aux-Roses, established an important feedback and developed a sound methodology for radiological characterization. This ...

  • Need for restoration of the nuclear knowledge management in Serbia

    Nuclear programmes in former Yugoslavia have been supported by comprehensive research and development (R&D), educational programmes and pertinent training in the country and abroad. Three research reactors and one nuclear power plant (NPP) were constructed and operated with the significant participation of domestic experts. Since 1989, the nuclear expertise has deteriorated considerably in ...

  • Knowledge management for a new nuclear power infrastructure

    The introduction of a nuclear power programme as a part of national energy strategy requires a complex consideration of many aspects of national infrastructure. Countries embarking on a new nuclear energy programme have the opportunity to establish effective knowledge management systems and processes from the outset, with the added benefit of readily available hard and software systems designed ...

  • Education for the nuclear power industry: Swedish perspective

    In the Swedish nuclear power industry staff, very few newly employed have a deep education in reactor technology. To remedy this, a joint education company, Nuclear Training and Safety Center (KSU), has been formed. To ensure that nuclear competence will be available also in a long-term perspective, the Swedish nuclear power industry and the Swedish Nuclear Power Inspectorate (SKI) have formed a ...

  • Opinion: Nuclear Waste Management and New Build

    Keywords: nuclear power, Generic Design Assessment, CO2 emissions, radiological protection, thermal oxide reprocessing, Radioactive Substances Act, Ionising Radiations Regulations, decommissioning and remediation of nuclear sites INTRODUCTION The history of designing, constructing and commissioning new nuclear power stations in the UK is not, it must be ...


  • Nuclear energy strategies in the UK and Finland: a critical evaluation on current and future prospective

    Nuclear strategies of the UK and Finland are a widely debated area. With power plants, both fossil fuelled and nuclear powered, in the two countries about to expire, now is the time to make decisions to take their energy security and supply well into the forthcoming century. With this in mind, policies have been made within the European Union to reduce 20% carbon emissions by 2020 and 60% by ...

  • A critique of the Department of Energy's environmental programme for the proposed high-level nuclear waste repository at Yucca Mountain, Nevada, USA

    Legislative standards, regulatory provisions, and US Department of Energy (DOE) policies have defined the environmental programme to study the planned high-level nuclear waste repository site at Yucca Mountain, Nevada. The DOE has limited environmental data collection for purposes of monitoring and mitigating impacts of proposed characterisation activities and repository development. Most of the ...

  • Multi-criteria decision support and stakeholder involvement in emergency management

    Decision-making in emergency management involves many parties with different views, responsibilities and interests for which a consensus must be found. Multi-Criteria Decision Analysis (MCDA) can help to ensure transparency in such decision processes. This paper describes the application of MCDA in nuclear emergency and remediation management and the experiences gained from conducting moderated ...

  • Mitigation of workplace radon gas concentration using high–performance epoxy resin coating

    The indoor radon gas released from concrete was measured using a 0.65 × 0.65 × 0.65 m fabricated concrete slab room, simulating a workplace. The indoor radon gas concentration was monitored, and the remediation method was examined. Radon concentrations were monitored using Radon Monitor Model 1023 from Sun Nuclear. Results show that average radon concentrations reached 111 ...

  • Geostatistical Methodology For Waste Optimization Of Contaminated Premises

    Summary At the end of process equipment dismantling, the complete decontamination of nuclear facilities requires the radiological assessment of residual activity levels of building structures. As stated by the IAEA: “Segregation and characterization of contaminated materials are the key elements of waste minimization”. From this point of view, the set up of an ...

  • Radioactive Clean-up

    Radioactive, nuclear, or radiation clean-up is considered as the most dangerous, difficult, and costly remediation activity after a nuclear disaster or accident.  The contamination may be found in the air, water, and soil, as wells as equipment and buildings (USEPA, 2010). Radioactive material is unstable, while the nuclei of radioactive atoms emit ionizing radiation (i.e., alpha ...

  • Radioactive Clean-up

    Radioactive, nuclear, or radiation clean-up is considered the most dangerous, difficult, and costly remediation activity after a nuclear disaster or accident.  The contamination may be found in the air, water, and soil, as wells as equipment and buildings (USEPA, 2010).Radioactive material, unlike most matter, is inherently unstable. Over time, the nuclei of radioactive atoms emit what's ...

  • 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 ...

  • Characterization Of A Deep Radiological Contamination: Integration Of Geostatistical Processing And Historical Data

    Summary Emerging in the early 80’s, decommissioning is more than ever a major issue since hundreds of sites and facilities worldwide will end their operations over the next decades. Decontamination and remediation projects are all the more sensitive since they could last several years and turn out to be highly costly if not well-prepared. The key lies in an adequate contamination ...

  • 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 ...

  • Interpreting the Contaminated Land Regime: Should the ‘Polluter’ Pay?

    Keywords: contaminated land, 'polluter pays' principle, stewardship Abstract: The contaminated land regime is not as effective as it could be. It is suggested that part of the reason for this is that enforcing authorities cannot afford to clean up land at a faster rate. Yet they are reluctant to recover their costs from Class B persons. There is evidence that local ...
