MDPI - 2016 - Radiological Assessment on Interest Areas on the Sellafield Nuclear Site via Unmanned Aerial Vehicle. Journal of Environmental Radioactivity Volume 151, Part 1, January 2016, Accumulation of Sellafield-derived radiocarbon (14C) in Irish Sea and West of Scotland intertidal shells and sediments. Open Access Highlights We measure 14C activity in shells and sediment at sites on the UK west coast. Mussel shell activity varies in response to average 14C discharges from Sellafield. Shell activities reflect species feeding habits and ecological niche. NE Irish Sea inorganic sediment activity will gradually increase. Increases in sediment activity will occur at remote sites on the Scottish west coast. Abstract The nuclear energy industry produces radioactive waste at various stages of the fuel cycle.
Keywords Radiocarbon; Sellafield; Intertidal; Mollusc shell; Sediment 1. The Sellafield nuclear fuel reprocessing plant (formerly known as Windscale), located in Cumbria on the North West coast of England (Fig. 1), is the primary source of anthropogenic radiocarbon (14C) discharges to the UK environment. BBC 29/10/15 Whisky distillery grain waste could tackle radioactivity. Image copyright Thinkstock Grain after it has been used for making whisky could be put to a new purpose in the clean up of radioactivity at the Dounreay nuclear site near Thurso. Scientists have begun tests on the use of spent grain from distilleries and also seaweed, crab shells and coffee grounds in absorbing Strontium-90. The radioactive isotope is present in liquid waste inside Dounreay's Shaft. Sunk in the 1950s close to the shores of the Pentland Firth, The Shaft plunges 65.4m (214.5ft) below ground. Radioactive waste was disposed there from 1959 to 1977, when an explosion ended the practice.

Thurso's Environmental Research Institute, which is part of the University of the Highlands and Islands' North Highland College, has started the investigation into the potential of spent grain, seaweed, shells and coffee grounds. SELLAFIELDSITES 01/03/16 Nuclear clean-up milestone makes Sellafield safer. Sellafield Ltd has taken its “most significant stride ever” in the 100 year mission to clean up the UK’s most complex nuclear site. Workers have now removed the entire bulk stocks of historic nuclear fuel from the Pile Fuel Storage Pond. The achievement came after decommissioning teams lifted the final skip of ‘metal fuel’ from the pond via a remote controlled process. Retrieval of the pond’s ‘canned fuel’ inventory was successfully completed in October 2015.
The work means radioactivity levels at the 68-year-old pond have been cut by 70 per cent, vastly reducing the risk it poses to people and environment. The milestone is the most visible sign yet of progress in the Nuclear Decommissioning Authority’s century long programme to clean-up the legacy of Britain’s early nuclear industry. This project was commissioned and delivered under the management of Nuclear Management Partners (NMP).
More than half a century on, Sellafield is now Europe’s biggest environmental restoration project. FSA 28/10/15 Radioactivity report published.

BBC 26/08/13 Future of Sellafield plant in doubt. British Nuclear Fuels (BNFL) has acknowledged that the Sellafield nuclear plant in Cumbria is to shift focus from reprocessing spent nuclear fuels to managing radioactive waste. Its statement comes in response to a newspaper report which suggested that Sellafield's Thorp reprocessing plant - which converts spent fuel rods into uranium and plutonium - would close by 2010.
Closure would have both symbolic and practical implications for the future of the nuclear industry in Britain. Nuclear reprocessing was once seen as the key to almost unlimited power generation. Britain has built its nuclear industry largely on reprocessing waste for other countries - countries which may now have to reconsider the future of their own nuclear industries.
Hopes dashed In its statement, the BNFL said its current order book of contracts extends to 2010 - but refused to confirm that was the date envisaged for the closure of Thorp's reprocessing activities.

Épidémiologie populaire : les premiers cas de leucémies autour de Sellafield. WORLD NUCLEAR NEWS 23/04/14 High-level waste arrives in Japan. The fourth and largest shipment so far of high-level waste from the UK to Japan has been completed. All such waste, resulting from the reprocessing of used reactor fuel, should be returned from the UK to Japan by the end of the decade. The Pacific Grebe, carrying five large flasks holding 132 canisters of waste in vitrified glass form, arrived in Japan yesterday having travelled via the Cape of Good Hope and the south-western Pacific Ocean. The Pacific Grebe is classed as an INF 3 vessel, certified to carry plutonium or used nuclear fuel up to any level of radioactivity. It is owned by Pacific Nuclear Transport Ltd, which is majority owned by International Nuclear Services (INS), itself part of the Nuclear Decommissioning Authority that owns the Sellafield site along with all other assets from the UK's former national nuclear program.
The shipment is the latest in a program to return foreign-owned waste stored in the UK to its country of origin. NUCNET 05/02/15 German-UK Consortium Wins £150 Million Sellafield Waste Facility Contract. 05.02.2015_No27 / News Decommissioning 5 Feb (NucNet): A consortium comprised of the German M+W Group and the UK’s James Fisher Nuclear has won a £150 million (€190 million) contract for the development of a nuclear waste storage facility at the Sellafield nuclear site in Cumbria, northwest England. Stuttgart-based M+W Group said in a statement that the contract, awarded by Sellafield Ltd, the company that manages and operates the site, includes the engineering, procurement, construction and commissioning of a nuclear waste import and storage facility which will be designed and built especially for the Sellafield site. The project, called the Box Encapsulation Plant Product Store Direct Import Facility, will provide the capability to transfer and store contained intermediate-level waste (ILW).
The statement said the facility, scheduled for completion in 2017, will play an integral part in the long-term plan to reduce the hazard on the Sellafield site. BBC 31/01/14 Sellafield partly closed after 'above normal' radiation. 31 January 2014Last updated at 09:32 ET A perimeter alarm detected "elevated" radioactivity The Sellafield nuclear reprocessing plant in Cumbria is partially closed after "elevated levels of radioactivity" were detected.
Each building was checked after a perimeter alarm was triggered at the north of the site. The company later said it was naturally occurring background radiation and not attributable to any issue or problem with any operation on site. A spokesman stressed there was no risk to the public or workforce. He added: "There can be no guessing on nuclear sites". Rory O'Neill, director of stakeholder relations, said: "One of the 20-odd site perimeter monitors that we have is registering above normal levels of radiation. "It's not a level that would trigger any kind of activity on or off site. 'Right decision' Part of the plant is being cleared to allow detailed investigations and the "relevant experts" are on site, a Sellafield spokesman said. Continue reading the main story. PAPERBLOG 05/02/14 Des niveaux élevés de radioactivité détectés sur le site nucléaire britannique de Sellafield. Publié le 05 février 2014 par Lenergiedavancer La direction du consortium Nuclear Management Partners (NMP) a annoncé, vendredi 31 janvier, que des niveaux anormalement élevés de radiation ont été détectés dans le Nord Ouest de l’Angleterre, sur le site nucléaire de Sellafield, le plus vieux et le plus gros complexe nucléaire européen. « Les niveaux de radioactivité détectés sont au-dessus de la normale mais bien en-dessous d’un niveau qui exigerait que le personnel prenne des mesures sur ou en dehors du site« , rassure la société. « Le personnel continue de travailler et les usines de fonctionner, tandis que l’enquête se poursuit« , conclut-t-elle.
De son côté, le gouvernement britannique estime qu’ »à l’heure actuelle, il n’y a pas de raison de penser que l’incident est plus grave qu’il n’a été rapporté« . Le site a connu plusieurs incidents nucléaires Sellafield, situé dans le comté de Cumbrie à la frontière avec l’Ecosse, est le plus vieux et plus gros complexe nucléaire européen.
INDEPENDENT 12/03/15 Ultimate cost of Sellafield clean-up 'cannot be forecast' Stephen Lovegrove, the Department’s Permanent Secretary, told The Independent that the huge range in the current estimate for decontaminating the Cumbrian site – £88bn to £218bn – illustrated the “level of uncertainty” in the forecasts. Mr Lovegrove was speaking after a hearing of the Public Accounts Committee yesterday afternoon. He told MPs that it was “impossible to know” the costs of the detoxification of one of the world’s most hazardous nuclear sites, a job that will not be completed until well into the 22nd century. “We still do not know by any stretch of the imagination all the technical challenges of the site,” Mr Lovegrove said.
“The difficulties are pretty much unprecedented.” Dame Ann McGuire, a former Labour minister who sits on the committee, said: “We know we have to be very aware of the safety issues … but the taxpayer needs some reassurance that this isn’t just going to be a blank cheque” for the private sector.
