  • @lillymunster There are several technical challenges regarding the fast breeder technology that are yet to be overcome. One of them is due to the nuclear reactions inside a fast breeder reactor not being self-sustainable. Once there is a power loss, the system shuts down and it is very hard to restart. That's one of the biggest advantages and one of its biggest faults as well. The Finnish prototype aims to test some new ways to tamper with that situation but it is not certain that it will succeed. And apparently this project has met several difficulties along the way. As of this date it is not certain when it will be ready to start operating.

  • I set an article for tomorrow that outlines the basics of the US and other countries spent fuel problems. It includes all the information for public feedback on the NRC spent fuel program that is going on now until Feb 17th. If people see other aspects we should cover in depth on spent fuel let me know, or other things to add on the info so far.

    We covered the Castor transport issue during the protests and did some on MOX and Japan's fuel cycle early on. Is there more on those to cover? Others I have overlooked?

  • @Pedro Jesus I thought about adding something about the finnish site that is the deep underground one. I could add more on the Uk one that I did. I put some about the UK fuel cycle, mox and fast breeder attempts to solve theirs but could add more. I am unfamiliar with Spanish or Swedish ones.

  • The taxpayer will have to stump up almost £250m more to bail out the Nuclear Decommissioning Authority in the next financial year after falling asset sales and rising expenditure cut its income by 17.5%.

    The shortfall is revealed in the NDA's just-published draft business plan for 2012-15, which shows the impact of being unable to offload land to the private sector for new nuclear plants and the end of the contracts to supply Japan with mixed-oxide fuel.

    The setback will give more ammunition to environmentalists and other critics who argue that the wider nuclear industry is infamous for cost overruns and calls on public funds.

  • @UKVal there was a point last summer where they were discussing trying to revive the mox program or make mox fuel and then just bury it. It seemed like there were some in the UK program that just couldn't get past all the money they spent on the MOX program

  • The Government gave the go-ahead yesterday (1st DEc 2011) for a controversial proposal to convert Britain's plutonium waste into mixed oxide (Mox) nuclear fuel that could be "burned" in a new generation of nuclear power plants.

    The decision, which ends decades of uncertainty on how to deal with a growing stockpile of more than 112 tonnes of plutonium waste, was presented as a written Parliamentary statement by the energy minister, Charles Hendry. www.independent.co.uk

  • @UKVal wow. There was a news article earlier this week where someone hinted the reactors wouldn't be built. Are they still planning on building some new reactors in the UK or just burn this in the existing ones?
    by lillymunster 1/27/2012 7:00:56 PM

  • @lillymunster yes -it's not just the money they've spent, it's also the UK has such huge stockpiles - much accepted from other countries - & something has to be done
    by UKVal 1/27/2012 7:01:37 PM

  • @lillymunster There are plans to build new reactors at several exisiting sites. What's been under review is plans for a fast-reactor & thast may well not go ahead (I hope!)

  • Fast breeder reactors can be a short term solution for existing nuclear waste but they would only perpetuate the nuclear power industry for another 5 or 6 decades. The question is, are we willing to let that happen?

  • @lillymunster - reprocessing is regretably a UK speciality: this article gives some info:
    by UKVal 1/27/2012 7:13:22 PM

  • The first shipment of highly radioactive waste from the UK has left the Sellafield nuclear site, the BBC has learnt.

    It has been loaded onto a ship specifically designed to carry nuclear waste that will sail for Japan later.

    The waste is a by-product of nuclear fuel spent by Japanese reactors that was sent to the UK for reprocessing during the 1980s and 1990s.

    Some campaigners have criticised the shipments, saying they are dangerous.

    "It is highly irresponsible for the industry to still be sending this kind of material across the world," said anti-nuclear campaigner Martin Forward.






    EYEWITNESS



    Jorn Madslien, business reporter, Sellafield


    Standing next to a 113-tonne metal cylinder filled to the brim with highly radioactive waste is a good way to get the heart racing - especially when that cylinder is dangling mid-air from a moving crane.

    But the small group of workers at the Sellafield nuclear complex remain calm during the careful loading of the first ever high-level nuclear waste shipment set to leave the UK.

    But if the workers are cool, their cargo is hot. The flask, which is being shipped to Japan, contains 28 steel canisters filled with high-level nuclear waste, each emitting heat.

    As I brush against the steel surface, I can feel a warm breeze of air coming from the shiny metal.

    Following the journey of the waste



    But Sellafield spokesman Mike Johnson said the site was simply fulfilling its contractual obligations, and government policy, in transporting the waste safely.

    Only two countries, the UK and France, have been engaged in the reprocessing of spent nuclear fuel from power stations.

    The process involves extracting reusable uranium and plutonium from the fuel, leaving behind a liquid waste.

    Japan has storage facilities in place already, having received 12 shipments of high level nuclear waste from France in recent years.

    Over the next decade, high-level waste will also be returned to European countries.

    Returning waste to countries that have benefited from nuclear energy production is in line with both global agreements and UK government policy.

    Profitable shipment

    For Sellafield, it is also a source of revenue, as the company - which runs the site under a contract with the Nuclear Decommissioning Authority - is being paid by the government for meeting targets set as part of a complex contract that involves the decommissioning, reprocessing and waste management at the site.

    "This is a performance-based milestone," Mike Johnson, executive director of Sellafield's waste and effluent disposal, told BBC News. "This is one of the ways we earn our fees."

    Sellafield declined to reveal the payment details.

    Revenue loss

    Sellafield's high-level nuclear waste storage is one of the most concentrated sources of radioactivity anywhere in the world

  • @UKVal So if they ever decide to just vitrify it all does the UK have a long term facility to store it?
    by lillymunster 1/27/2012 7:18:00 PM

  • @lillymunster No facilty at present -Government asked local authorities to volunteer for a long ternm storage facility & only Cumbria expressed interest - hence meeting described in article posted from local paper Times & Star below. Cumbria already has most of the waste as it hosts Sellafield. It's 1 of the poorer regions of the UK with little industry or jobs other than toursim. THe Cumbrian Lake District is arguably the most beautiful part of England & an area I know well.

    by UKVal 1/27/2012 7:35:48 PM

  • Some people argue that there is already enough evidence to show that the whole of West Cumbria is geologically unsuitable. See www.davidsmythe.org for more details.



    After looking at a range of views and evidence our opinion is that the argument that all of West Cumbria should be excluded as unsuitable at this stage is not generally accepted within the professional geological community.



    In the absence of clear, detailed evidence showing that all of West Cumbria should be ruled out, our initial opinion is that there is enough possibly suitable land to make further investigations worthwhile.



    We believe it will only be possible to find out if there is a suitable site for a repository if there are more detailed investigations, including boreholes, to test the rocks in the area.
