  • The Future of Nuclear Power Plants

    With the blast of the French nuclear power plant a few weeks ago, safety of nuclear power plant designs has fallen under more scrutiny. Although according to sources the blast took place in the turbine hall and no nuclear leak was found, this event has brought more attention to improved design and operation standards. Following the incident earlier this month Toshiba, a Japanese ...

  • 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 ...

  • Assessing the Impacts of the Iran Nuclear Deal on Climate Change

    Introduction On July 14, 2015, the international economic boycott levied against Iran was scheduled to conclude. In concert with the European Union and the P5+1, the Islamic Republic agreed to a Joint Comprehensive Plan of Action (JCPOA) whereby its capacity for nuclear development would be dramatically curtailed. Among other requirements, Iran is mandated, for a period of 15 years, to ...

  • 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 ...

  • Is nuclear power our energy future — or a dinosaur in a death spiral?

    Identical data yield drastically different conclusions about the role nuclear will play in meeting climate goals. Nuclear power is dead. Long live nuclear power. Nuclear power is the only way forward. Nuclear power is a red herring. Nuclear power is too dangerous. Nuclear power is the safest power source around. Nuclear is nothing. Nuclear is everything. It is now generally agreed ...

  • Effect of cathode electron acceptors on simultaneous anaerobic sulfide and nitrate removal in microbial fuel cell

    The current investigation reports the effect of cathode electron acceptors on simultaneous sulfide and nitrate removal in two-chamber microbial fuel cells (MFCs). Potassium permanganate and potassium ferricyanide were common cathode electron acceptors and evaluated for substrate removal and electricity generation. The abiotic MFCs produced electricity through spontaneous electrochemical ...

  • Management of water resources assessment for nuclear power plants in China

    To deal with global warming and energy shortages, the nuclear power industry has flourished in China. Operation of a nuclear power plant consumes a large amount of water and discharges radioactive wastewater into nearby water bodies. Therefore, assessment and management of water resources are crucial for such projects. This article proposes the contents, procedures and methods of water ...

  • 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 ...

  • Simultaneous pollutant removal and electricity generation in denitrifying microbial fuel cell with boric acid-borate buffer solution

    A double-chamber denitrifying microbial fuel cell (MFC), using boric acid-borate buffer solution as an alternative to phosphate buffer solution, was set up to investigate the influence of buffer solution concentration, temperature and external resistance on electricity generation and pollutant removal efficiency. The result revealed that the denitrifying MFC with boric acid-borate buffer ...
