  • The UK`s plan for nuclear decommissioning, 2008-2011

    The Nuclear Decommissioning Authority (NDA) is a non-departmental public body set up under the Energy Act 2004, responsible for the decommissioning and clean-up of the UK’s civil public sector nuclear sites. We do not directly manage the sites for which we are responsible. Instead we contract out the delivery of site programmes to Site Licence Companies (SLCs), which remain responsible for ...

  • 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 ...

  • Nuclear Waste: Greatest environmental challenge facing society

    Dr Tim Johnson discusses how we can tackle the nuclear waste epidemic. A world full of waste They say you can tell a lot about a society by what it throws away. Like me, I’m sure you can recall the excitement of archaeologists on numerous TV documentaries, sifting through the remains of a rubbish dump or ‘midden’ on the edge of some ...

  • Book Reviews: Nuclear Law - The Law applying to nuclear installations and Radioactive substances in its Historical context

    This is an important and timely book. Not so very long ago the future of nuclear energy appeared to be a matter principally of decline, decommissioning and waste disposal. While these are all still features of considerable importance, the past few years have seen a remarkable transformation in the fortunes of nuclear energy. With zero emissions of greenhouse gases in operation, the attractions of ...


  • 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 ...

  • 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 ...

  • 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 ...
