  • Geostatistical Sampling Optimization and Waste Characterization of Contaminated Premises

    Abstract This methodological study presents a geostatistical approach suitable for radiological evaluation in nuclear premises. By modelling the spatial continuity of activities, geostatistics provide sound methods to estimate and map radiological activities, together with their uncertainty. The main geostatistical principles are first recalled and illustrated on a real premise ...

  • An ontological approach to knowledge management for sustainable nuclear decommissioning

    Nuclear decommissioning design and operational knowledge may remain relevant over many decades. Designing sustainable operations today requires meaningful simulation of future events, which in turn relies on the accurate representation of all relevant current knowledge. In decommissioning, human agents may be as important for maintaining operational safety as technical systems, so simulations ...

  • Critical issues with 'minor league' nuclear infrastructures: the back end of the life cycle

    The paper attempts to draw attention to a number of issues that may go underplayed on the agenda of the critical infrastructure analysts concerned with risks: the vulnerabilities induced by nuclear research facilities facing decommissioning. The notion that the 'small nuclear' facility may show, in such circumstances, sizeable risks, even in comparison with the 'big nuclear' facility, in ...

  • Radioactive waste management in Italy

    After a short review of radioactive waste origins and inventories in Italy, the paper deals with the current major challenges that Italy has to cope with to pursue its radioactive waste sustainable management and safe disposal. Site restoration by Sogin of dismissed nuclear installations is part of the waste management challenge. The importance of assuring the highest levels of safety culture ...

  • 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 ...

  • Nuclear power: ecologically sustainable or energy hot potato? A case study

    We are facing the prospect of fossil fuels running out. The magnitude of the hydrocarbon resource gap and lack of alternative energy sources leaves us with few choices. The gap between supply and demand must be met through either increased efficiency or increased nuclear/renewable energy production. With the proposed development of ten nuclear power stations, government appears committed to using ...

  • The Belgian Nuclear Research Centre and the possibilities for cooperation with China

    This paper gives a short overview of the activities of the Belgian Nuclear Research Centre (SCK?CEN) and the role it can play in the cooperative agreement that was established between the China National Nuclear Corporation (CNNC) and SCK?CEN. Indeed, the current established cooperation on nuclear energy research between China and Belgium should make use of the nuclear research experiences and ...

  • New regulations for release in Germany: a chance for minimisation of radioactive waste and reduction of costs

    The EURATOM Basic Safety Standards provided the occasion to establish comprehensive clearance regulations in German law. The new German Radiation Protection Ordinance contains detailed regulations regarding clearance of radioactive substances with negligible radioactivity from practices subject to authorisation. For about 300 radionuclides, there are mass- and surface-specific clearance levels ...

  • 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 ...

  • 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 ...

  • The assessment of the environmental and public impact of the on-shore storage facility for dispositioned N/SM reactor compartments in the North-West region of Russia

    This paper deals with the environmental and public impact of radiation factors of the land-based storage facility being designed for dispositioned N/SM reactor compartments in the Russian North-West region. The capacity is sized to accommodate reactor compartments of all the Russian North Navy N/SM after their disposition. Based on the study results, it can be concluded that the creation of this ...

  • Project - James Fisher Nuclear (JFN)

    James Fisher Nuclear (JFN) supplies specialist engineering, manufacturing, and technical services for decommissioning nuclear facilities. Once nuclear facilities reach the end of their operational life, all nuclear materials, plants, and buildings must be removed and properly disposed of, a process known as “decommissioning”. When done correctly, decommissioning safely and ...

  • Can towns near Japan`s Fukushima nuclear plant recover?

    A few signs of life are returning to this rural town made desolate by the Fukushima nuclear disaster four-and-a-half years ago: Carpenters bang on houses, an occasional delivery truck drives by and a noodle shop has opened to serve employees who have returned to Naraha's small town hall. But weeds cover the now rusty train tracks, there are no sounds of children and wild boars still roam around ...
