Nuclear super-fuel gets too hot to handle

Tuesday, April 22, 2008

It seems like a no-brainer. Make uranium burn stronger, hotter and longer in nuclear reactors, and you'll need less fuel, and there'll be less waste to deal with when it has been exhausted.

For decades, nuclear operators have done just that, but emerging safety and waste-disposal issues are raising questions about this approach. The latest high-efficiency fuel may prove to be unstable in an emergency, and so poses a greater risk of leakage of radioactive material into the environment. What's more, the waste fuel is more radioactive, meaning it could prove even more difficult than existing waste to store in underground repositories.

Aon warns of supply risk for UK nuclear

Friday, April 18, 2008

London, 10 April: Insurer Aon Corporation has warned that the UK's plan for a nuclear power renaissance must take into account risks of interruptions to the supply of uranium fuel.

The UK government is easing planning restrictions, in a bid to encourage private companies to build a new generation of nuclear power plants to help replace the existing, aging fleet of reactors. At a speech on 26 March, UK Business Secretary John Hutton called this new push for nuclear "the most significant opportunity for our energy economy since the exploitation of North Sea oil and gas".

Depleted uranium turns earthworms into glowworms

Thursday, March 20, 2008

EARTHWORMS WERE pushed into the firing line last week after a resumption of the testing of depleted uranium shells at Dundrennan.

Significant levels of radioactive uranium isotopes were found in the flesh of worms at the Ministry of Defence's Dumfries weapons range last year. Despite concerns from environmentalists and the international community, the MoD last week started a series of tests of depleted uranium (DU) shells, supposed "safety checks".

Armenia to set up uranium prospecting joint venture with Russia

Friday, March 7, 2008

YEREVAN, March 6 (RIA Novosti) - The Armenian government authorized on Thursday the establishment of a joint venture with Russia for the additional prospecting of uranium deposits in the South Caucasus republic.

Russia's state nuclear corporation Rosatom and the Armenian environmental ministry agreed in February to set up a joint venture on a parity basis for the additional prospecting of Armenian uranium, which will be enriched in a specialized international center in Angarsk, East Siberia.

Shipping bottlenecks may halt nuclear renaissance

Wednesday, February 27, 2008

LONDON, Feb 27 (Reuters) - Nuclear power -- back in favour in some circles on concerns over global warming -- may face supply problems as worries over the safety of radioactive material limit its movement around the globe.

After decades of plant closures amid opposition from the anti-nuclear lobby, many governments are now planning to build new reactors to try to cut dependence on oil and coal which put carbon dioxide into the atmosphere.

Ecologists Warn of Dangers to City of Nuclear Waste Cargo

Friday, January 25, 2008

By Galina Stolyarova, the St. Petersburg Times

As 2,000 tons of radioactive cargo arrived at St. Petersburg’s port from Germany on Thursday, environmental groups took to the streets to inform city residents about the growing imports of nuclear materials and the dangers the trade imposes.

The MV Schouwenbank cargo ship, carrying containers with a total of 2,000 tons of depleted uranium hexafluoride, came from the Gronau uranium enrichment facility that belongs to Urenco Deutschland. The radioactive load on board the ship is due to be sent by rail to the town of Novouralsk in Siberia for reprocessing and storage.

Indonesia pushing for nuclear power, despite safety concerns

Tuesday, January 22, 2008

By Jakarta correspondent Geoff Thompson

The Howard government made no secret of its support for nuclear power both at home and in the region. Now, one of the country's closest neighbours, Indonesia, is ramping up its own nuclear industry. It is hoping for Australia's continuing technical support - and its uranium. But the threat of earthquakes in Indonesia continues to prompt safety concerns.

Russian Contractors Decide to Raise Belene NPP Electricity Price

Tuesday, January 8, 2008

The electricity that NPP Belene will generate when finished will cost at least 4.5 euro-cents per kilowatt-hour, which is by one euro-cent more than the price initially announced by Atomstroyexport. The consumers' price of the electricity from NPP Belene is still uncalculated
