    1989-01-01

    Cumbrians Opposed to Radioactive Environment (CORE), give help to people who feel they have a just claim for compensation as a result of radiation at Sellafield. Two cases are outlined to illustrate the types of cases that CORE deals with. Both concern former employees of British Nuclear Fuels Ltd. who operate the Sellafield site. (author)

  4. Product quality and process control in the Windscale Vitrification Plant

    International Nuclear Information System (INIS)

    Beveridge, G.D.

    1991-01-01

    The Windscale Vitrification Plant (WVP) is owned and operated by British Nuclear Fuels (BNFL) at the Sellafield Site in England. The purpose of the facility is to condition the high level liquid waste, resulting from the reprocessing of spent fuel into a suitable solid form for ultimate disposal. The form chosen is a borosilicate glass matrix which meets both the needs of long term durability and plant operability. A considerable amount of work has now been carried out in order to demonstrate that product quality can be guaranteed through process control. This work has ranged from very small scale lab. studies to full scale production plant trials. WVP entered active service in July 1990 and is currently dealing with the arisings from over 30 years of reprocessing

  5. Windscale - power versus pollution

    International Nuclear Information System (INIS)

    Bonney, S.

    1977-01-01

    Protests from British environmental groups, scientists, politicians and private citizens has forced the Government to postpone a decision on plans to create the world's largest nuclear fuel oxide reprocessing complex at Windscale, on the north-west coast of England. Subjects considered here are the vast increase in the the quantity of lethal nuclear waste stored at Windscale, the risk of explosion or plant malfunction causing radioactive fall-out, the increased radioactive discharge into the Irish Sea and into the atmosphere and the danger of terrorism or sabotage. It is stated that critics of the Windscale project have yet to be convinced that the nuclear power industry is as risk-free as its proponents maintain in public statements. To satisfy the great anxieties shared by a large number of people about the expansion plan, a full public inquiry is essential. (U.K.)

  6. The Windscale experiment

    International Nuclear Information System (INIS)

    Blackith, Robert

    1984-01-01

    The discharge of radioactive waste into the Irish Sea from the Windscale reprocessing plant in Cumbria is discussed from an Irish viewpoint. A history of accidents at the plant is reviewed, and past, present and future levels of discharge to the environment are outlined. The effect on the Irish population of discharges to the marine environment is evaluated by consideration of the food chain and the exposure pathways to man, in particular the concentration of radioactive caesium and plutonium in the flesh of fish in the Irish Sea. The general health effects attributed to radiation exposures are given, and a cluster of Downs Syndrome babies born to mothers who were at the same school in Co. Louth is attributed to increased exposure during the 1957 fire at the Windscale plant. The author concludes that, because of military implications and the need for plutonium for nulcear weapons, the reprocessing plant will continue to operate, but with greatly reduced levels of discharges permitted

  7. Judgement on Windscale

    International Nuclear Information System (INIS)

    Roberts, G.C.; White, I.F.

    1978-01-01

    A summary is given of the findings of the report on the Windscale Inquiry into the application by British Nuclear Fuels Limited for planning permission to establish a plant for reprocessing irradiated oxide nuclear fuels (The Windscale Inquiry. Report by the Hon. Mr. Justice Parker, 26 January 1978, Vol.1, Report and Annexes 3 to 5, HMSO). Particular attention is given to comments in the report on the ICRP and NRPB, radiation protection standards, and the risks associated with fuel reprocessing. The bases of the judgements made are given, together with Mr. Justice Parker's recommenda-tions for the setting of discharge limits, monitoring discharges and levels of environmental radioactivity, and the assessment of what constitutes a tolerable risk to the public.

  8. Selling Sellafield

    International Nuclear Information System (INIS)

    Milne, Kirsty.

    1987-01-01

    The article describes a trip to the Sellafield reprocessing plant arranged by BNFL for journalists. The train journey from London and the actual tour round the Sellafield site and visitor centre are described briefly. Several protest groups were encountered on the way but the point made is that in encouraging visitors to the site and explaining what is going on there BNFL is trying to be more open in its dealings with the public in an effort to inform, reassure and lessen mistrust.

  9. Training of health physics services staff at the Sellafield Works of British Nuclear Fuels

    International Nuclear Information System (INIS)

    Tagg, B.

    This paper describes the qualifications required and the training of health physics non-industrial and industrial staff who provide a radiological protection service to the Sellafield site. The training offered may consist of formal group instruction, programmed learning using written texts, videotape lectures, and on-the-job training by line management. Experience has shown that formal oral and practical instruction to small groups is the most effective form of training when supplemented by on-the-job training

  10. From passive storage to daily waste retrieval; changing the working culture at Sellafield's pile fuel storage pond

    International Nuclear Information System (INIS)

    Carlisle, Derek

    2013-01-01

    The Pile Fuel Storage Pond (PFSP) was built in 1948/50 to treat materials from the Windscale Piles. Multiple operational regimes over the intervening 60 years have resulted in a complex inventory of spent nuclear fuels, solid and liquid intermediate level wastes. A coordinated programme of work, designed to retrieve and safely dispose of the pond contents, has been implemented to enable the decommissioning of the facility. The long period of passive storage operations which preceded the implementation of the programme meant that the operator was faced with a dual challenge of providing new technical capability and changing a working culture that was inappropriate for the dynamic environment required to successfully deliver the programme. It was recognised that the nature of the programme meant that implementing a standard manufacturing approach to operations would not be appropriate. In order to create a dynamic retrievals focussed working culture, the operator has vigorously embraced change programmes aimed at improving a number of working practices including encouraging innovation, managing integrated but flexible production schedules, and encouraging work-face problem solving. The combined impact of beginning to resolve the technical challenges and focussing on the delivery culture has resulted in the facility making a step change towards becoming fully retrievals operations focussed.

  11. Decommissioning the Windscale AGR

    International Nuclear Information System (INIS)

    Boorman, T.

    1987-01-01

    The advanced gas cooled reactor at Windscale (WAGR) is being dismantled, that is, all fuel and coolant will be discharged and the plant dismantled completely with waste disposed of to a permanent repository. It is the first power-producing reactor to be dismantled in the UK. From a study of the main categories of materials to be disposed of it can be seen that the task of reactor decommissioning can be considered as the segregation of waste materials into appropriate categories and their disposal according to the regulations governing those categories. In the radioactive categories (only 10% of the total) only low and intermediate level wastes are involved. The high level waste was from the spent fuel which has already been removed. The remote controlled cutting, handling and packaging equipment is described. All equipment to be used has first to be tested after development. One building has been allocated as the waste packaging building and modified suitably. Dismantling is seen as a feasible process. (UK)

  12. Sellafield: the nuclear legacy

    International Nuclear Information System (INIS)

    Black, Sir D.

    1985-01-01

    The paper concerns Sir Douglas Black's independent inquiry into cancer in young people living near the Sellafield Reprocessing Plant. The inquiry followed a Yorkshire Television documentary on the subject. Childhood cancer and the statistical methodology employed in the report are discussed, as answers to criticisms of the report. Also discussed are the Sellafield discharges and the incidence of childhood leukaemia near Sellafield. (U.K.)

  13. Windscale Report: a nuclear apologia

    International Nuclear Information System (INIS)

    Patterson, W.C.

    1978-01-01

    Government representatives have pointed repeatedly with pride to Britain's longest nuclear planning inquiry, The Windscale Inquiry, as a model of open examination of a sensitive nuclear proposal. The official Report of the Windscale Inquiry, published in March 1978, bears little relationship to the proceedings of the Inquiry, according to the author. Instead, the Report is a heavy-handed nuclear apologia, he says, so clumsily one-sided as to provoke unease even among many Britons previously unmoved by the issue which gave rise to the inquiry. Windscale, built following WW II to produce plutonium for Britain's nuclear weapons, is now operated by British Nuclear Fuels Ltd. In 1973, BNFL began to plan construction of a new full-scale oxide-fuel reprocessing plant. Protests delayed construction until the inquiry was planned and the inquiry team was formulated in March 1977. When the Inquiry ended, the inspector closeted himself to write the Report. The Report recommended that the oxide fuel reprocessing plant be built immediately. BNFL had asserted that the proposed thermal oxide reprocessing plant, THORP, was necessary for the management of spent fuel from British and other nuclear plants; that it was desirable for ''energy conservation,'' by recovering uranium and plutonium for re-use; that radioactive emissions within and outside the plant would pose no hazard; and that the servicing of foreign customers would not increase the risk of proliferation of nuclear weapons, but would rather help to persuade other countries not to reprocess their own fuel. The inspector agreed without qualification and with emphasis. In doing so he made no attempt even to describe the detailed evidence on either side, or to discuss the cases advanced by objectors. The author discusses the principal conclusions of the report and cites its futility

  14. Father's occupational exposure to radiation and the raised level of childhood leukemia near the Sellafield Nuclear Plant

    International Nuclear Information System (INIS)

    Gardner, M.J.

    1991-01-01

    The first indications that childhood leukemia rates may be raised near the Sellafield nuclear plant in West Cumbria, England, came from largely anecdotal evidence in a television program Windscale: The Nuclear Laundry shown during 1983. During subsequent years, various epidemiological studies have investigated the claim in more detail. Geographical analyses of childhood leukemia incidence in the northern region and mortality in England and Wales using routinely available data made the first contribution. As a result, it was confirmed that leukemia rates in the area, particularly the neighboring village of Seascale, were high compared to other districts, although not totally extreme. Cohort studies of children born in Seascale or attending schools in Seascale were carried out to resolve some of the difficulties of interpretation of geographical analysis. Cohort studies indicated that the excess of leukemia was concentrated among children born in Seascale and was not found among those moving in after birth and suggested that any causal factors may be acting before birth or very early in life. A case-control study of leukemia (and lymphoma) among young people in West Cumbria has examined potentially important individual factors in detail. The study demonstrated a relationship between the raised incidence of leukemia in children and father's recorded external radiation dose during work at Sellafield before his child's conception. The association can effectively explain statistically the observed geographical excess

    Frith, A.J.; Dickson, E.D.; Hewetson, J.A.; McCormick, K.

    2003-01-01

    The decommissioning of windscale Pile 2 Chimney resulted in the removal of one of most historically significant and prominent features of the Sellafield site. The project was the first large scale concrete ''free release'' operation to be undertaken on the Sellafield nuclear site, producing 4500 tons of concrete of which 3000 tons was demonstrated to be ''free release''. The paper describes the radiometric techniques employed in the characterisation and segregation of the concrete into low level waste (LLW), very low level waste (VLLW) and free release categories. It examines the robust solutions that were developed to meet the technical and regulatory challenges of the project, which included the definition of free release, the selection of averaging volumes, the testing and validation of the monitoring systems employed for ton quantities of concrete and the identification and removal of small numbers of fuel particles from the free release waste stream. As a result of interest shown by other BNFL and UKAEA decommissioning projects at Sellafield, the paper finishes by discussing ways in which the system may be developed to assay other waste streams.

  17. A comparison of the observed and the expected cancers of the haematopoietic and lymphatic systems among workers at Windscale

    International Nuclear Information System (INIS)

    Dolphin, G.W.

    1976-12-01

    Data are given about the cases of cancers of the haematopoietic and lymphatic systems among workers at Windscale Works, BNFL during the period 1950 to 1974. The number of cancers of these types expected to occur in the working population at Windscale has been estimated for the same period. For none of these types is the observed number of cancers significantly different at the 95% confidence level from that expected. (author)

  19. Sellafield - a nuclear licensed site

    International Nuclear Information System (INIS)

    Bloom, Phillipa.

    1987-01-01

    The report is based on the experience gained when visiting the Exhibition Centre at the BNFL Sellafield site and joining the hour-long coach trip round the site. The sights are recorded and a description given of the processes undertaken at Sellafield to reprocess the Magnox fuel and store the spent fuel from AGR reactors. The purpose of the main plant building, and the passage of the spent fuel through the various processes is described. Criticism is made of the safety record at Sellafield and a full and open debate on nuclear power is called for. (UK)

  20. Winning Public Confidence in Sellafield

    International Nuclear Information System (INIS)

    Preece, J. A.

    1991-01-01

    BNF operates the nuclear fuel reprocessing and waste management centre of Sellafield in North West England. It is the largest nuclear site in Britain and perhaps the most famous nuclear plant in Western Europe. It is famous largely because it has long been the target of anti-nuclear interests. Well organised, well funded and well informed anti-nuclear organisations, notably including Green peace and Friends of the Earth, have made propaganda capital based on a number of controversial claims: - that by importing spent nuclear fuel from overseas for reprocessing at Sellafield, BNFL was turning Britain into a nuclear dustbin for the world. That discharges of low level radioactivity from Sellafield cause unacceptable nuclear pollution and endanger health, that the radioactivity in store in various forms on site at Sellafield, for which no permanent disposal routes are yet available, are a danger to the public and constantly threaten a major nuclear accident

  1. The role of advertising in promoting Sellafield

    International Nuclear Information System (INIS)

    Cartwright, Bob

    1989-01-01

    During the last two and half years, British Nuclear Fuels havevspent approaching 9 million pounds on advertising, expenditure designed to increase the public's acceptance of nuclear power and BNFL's operations in particular. That money has been spent against a difficult background, the campaign having started just seven weeks after the Chernobyl disaster, although the strategy, was developed before Chernobyl changed so many people's attitude towards nuclear power. Sellafield was seen by many in the nuclear industry, and not only in Britain, as a major problem, and the public, judging by opinion research conducted at the time, shared that view. Research showed: Most people Saw BNFL as an environmental polluter and a danger to health; Sellafield was aeon as a dangerous place at which to work or near which to live; BNFL was seen as secretive and dishonest. One of the major argument for using advertising as the focal point of any major campaign is that, unlike press relations, it can be controlled. This was particularly important, as the press coverage was already bad, and something dramatic had to be done to change the situation. At first, we considered two fairly obvious strategies. To try and explain the benefits of nuclear power and BNFL's role, and secondly to explain the risks and put them into the context of other everyday risks. The campaign started in June 1986, with colour advertisements in magazines and newspaper supplements. Attached to the advertisement were invitation cards, with nine million printed. This was followed by a 50 second TV advertisement, broadcast nationally. Our aim to make the campaign newsworthy certainly worked. With the help of a public relations exercise, the TV ad was shown on a wide range of news programmes, and many newspaper articles were written about this new approach to selling nuclear power to the public. People started to visit Sellafield in ever increasing numbers. The biggest surprise was at the end of 1987, when Sellafield

  2. Cases of leukaemia in the Sellafield area: the ''Sir Douglas Black'' report

    International Nuclear Information System (INIS)

    Dousset, M.; Jammet, H.

    1984-01-01

    The report of this Advisory Group was published in the summer of 1984. Its conclusions can be summarised as follows: 1. Epidemiological surveys, although still incomplete, show that the incidence of cases of leukaemia and deaths caused by leukaemia in persons under 25 years of age is ''unusual'' in the village of Seascale and the Millom rural district. However, they are not unique and the same phenomenon can be found in comparable population groups located far away from any nuclear plants. 2. Taking all children born Seascale since 1950 who lived in the village up until 1980, their equivalent dose in the red marrow of the bone caused by Sellafield nuclear waste and the Windscale reactor fire of 1957 is only 13% of the equivalent dose due to background radiation. 3. The excessive leukaemia mortality rate at Seascale cannot be explained by radioactive waste. For this, a factor of 40 to 400 would be necessary. However, since doubts remain with respect to Sellafield nuclear waste, it must be temporarily concluded that the hypothesis of a connexion between the proximity of the nuclear plant and the excessive leukaemia rate cannot be fully eliminated. But neither can it be easily proven. The advisory Group recommendations are relating to: the surveys to be carried on; the inspection to be improved around the Sellafield plant; the incumbent regulations to be taken into consideration [fr

  3. Hydrogeological testing in the Sellafield area

    International Nuclear Information System (INIS)

    Sutton, J.S.

    1996-01-01

    A summary of the hydrogeological test methodologies employed in the Sellafield geological investigations is provided in order that an objective appraisal of the quality of the data can be formed. A brief presentation of some of these data illustrates the corroborative nature of different test and measurement methodologies and provides a preliminary view of the results obtained. The programme of hydrogeological testing is an evolving one and methodologies are developing as work proceeds and targets become more clearly defined. As the testing is focused on relatively low permeability rocks at depth, the approach to testing differs slightly from conventional hydrogeological well testing and makes extensive use of oilfield technology.

  4. BNFL Sellafield further public consultation

    International Nuclear Information System (INIS)

    1994-01-01

    The main issues raised during the further public consultation on the draft Sellafield authorisations for the discharge of radioactive wastes from the British Nuclear Fuel (BNFL) Sellafield site are outlined. An analysis of the categories and numbers of the 42,500 responses is made. The public consultation was based on five documents; a letter to consultees from the Department of the Environment and the Ministry of Agriculture, Fisheries and Food (MAFF); the report by Her Majesty's Inspectorate of Pollution and the Inspectorate of MAFF on their earlier consultation exercise; a paper by BNFL on the economic and commercial justification of the Thermal Oxide Reprocessing Plant (THORP); a statement of the Government's policy on reprocessing and THORP and a document prepared by BNFL on the environmental implication of THORP.

  5. The Windscale Fire of 1957: A Retrospective Assessment of its Impact on Ireland Utilising Environmental Archives

    International Nuclear Information System (INIS)

    Gallagher Donal

    2003-02-01

    A serious nuclear accident occurred on the 10th October 1957 at the UK Atomic Energy Authority's Windscale Works, resulting in the release of a large quantity of radioactivity, mainly nuclides of the noble gases and volatile elements, into the atmosphere from the reactor stack over a period of approximately 24 hours. A large number of measurements of the levels of radionuclide contamination were made throughout the UK and on the Europeanmainland in the aftermath of the accident. Comparatively few measurements were made in Ireland and the incident did not receive a great deal of public attention until many years later. The suggestion in1983 of a possible link between a cluster of Down's syndrome cases in Dundalk and the Windscale accident, led to acute public concern in Ireland that the north-eastern region of the country may have received significant fallout from this accident. This study has targeted these concerns and sought to determine the actual impact (if any) of the Windscale Fire on Ireland. Measurements of radioactivity levels in precipitation, settled dust and airborne particles, made at Dublin City and Valentia in October 1957 by the Irish Meteorological Service, have been re-examined to determine whether or not significant increases in airborne and deposited activity occurred in the aftermath of the accident. The results of atmospheric dispersion studies of the Windscale plume by other researchers, one based on a simple Gaussian plume model and the other on a more powerful Lagrangian puff trajectory model, have also been reviewed. In addition, an extensive programme of sampling and analysis was undertaken in which carefully selected environmental archives were examined to determine whether any traces of the Windscale 1957 'legacy' could be detected in event horizons corresponding to the late 1950's. Specifically, peat bog monoliths, lake sediment cores and tree ring sequences from the east and west coasts of Ireland were sampled and analysed using a

  6. The selling of Sellafield (the public image)

    International Nuclear Information System (INIS)

    White, David.

    1986-01-01

    The advertising campaign planned to restore the public image of Sellafield is discussed. Two aspects of the Sellafield site are being promoted especially, the first is that the discharges of long life radioactivity are being reduced. The second is the 'site accessibility' of Sellafield -BNFL is trying to encourage visitors to see for themselves what goes on at Sellafield. There is evidence that this will allay the fears and suspicions of the public. It is suggested, however, that providing information about nuclear power may be counter-productive as the concept of nuclear disaster may receive greater attention. The Sellafield site is difficult to promote whilst it continues to suffer leaks and it is suggested that the only way to promote Sellafield successfully may be by appealing to nationalism as the French have done in their nuclear campaign.

    This study of low-level liquid radioactive discharges from the British Nuclear Fuels Ltd Sellafield site into the eastern basin of the Irish Sea, prepared on the basis of existing publications and documents, reviews chemical forms and rate of discharges, physical oceanography, sediment distribution and fisheries of the Irish Sea, behaviour of radionuclides in seawater, association with sedimentary materials, accumulation of radionuclides by biological materials, environmental monitoring, surveillance and assessment of radiation exposure of the public and impact on the environment

  8. Design and development of effluent treatment plants for the Sellafield reprocessing factory

    International Nuclear Information System (INIS)

    Howden, M.

    1989-01-01

    The reprocessing of spent nuclear fuel has been carried out at Sellafield since the early 1950s. The storage of fuel in water filled ponds prior to reprocessing and the reprocessing operation itself results in the generation of a number of radioactive liquid effluents. The highly active liquors are stored in stainless steel tanks and will, with the commissioning of the Windscale Vitrification Plant, be converted into glass for long term storage and disposal. The medium and low active liquors are, after appropriate treatment, discharged to sea well below the Authorised Limits which are set by the appropriate Regulatory Bodies. Since 1960 these have been the Department of the Environment and the Ministry of Agriculture, Fisheries and Food. Even though the discharges have been well below the limits set, BNFL have for many years adopted a policy of reducing the levels of activity still further. Considerable progress has already been made, by changing reprocessing operations regimes but more importantly by the development and construction of specialised effluent treatment plants. Further reductions are, however, planned. Two major effluent treatment plants form the main basis of BNFL's policy to reduce activity discharges from Sellafield. The first, the Site Ion Exchange Effluent Plant, to treat storage pond water was brought into operation in 1985. The second, the enhanced Actinide Removal Plant to treat medium and low active effluents, is programmed to operate in 1992. (author)

    The Sellafield story is not unique but it can be used as one example of what can be achieved in a community close to a nuclear site. Over the past 12 years BNFL staff at Sellafield have worked diligently to win public acceptance in the local community around Sellafield. It has been an excellent example of teamwork, involving the workforce and the local community. It has taken a great deal of effort and finance and painstaking attention to even the most trivial issues to gain the publics' trust. Today, Sellafield and its activities underpin the economy of West Cumbria. The site employs just under 7000 people directly with a further 1500 in contracting roles

  13. BNFL Sellafield: post audit progress, December 1987

    International Nuclear Information System (INIS)

    1987-12-01

    The report of the safety audit at the Sellafield site was published in December 1986. In this, the Health and Safety Executive required British Nuclear Fuels (BNFL) to make improvements to the site and safety cases have had to be produced. These have now to be assessed by the Nuclear Installations Inspectorate. BNFL has undertaken programmes of maintenance, refurbishment and replacement of equipment. Much of this work was done in the shut-down maintenance period in the spring and summer. However, more work is needed to bring plants up a condition suitable for operating for the next ten years. BNFL have also started to decontaminate and decommission disused, contaminated, plants. This will generate a large amount of radioactive waste. BNFL have to build plants to containerise and encapsulate the waste prior to disposal. Waste disposal sites to complete the clean-up process are needed. The improvements to the engineering plants, to written procedures and to training, are reported. Changed attitudes are also noted. (U.K.)

  14. HSE investigation of leukaemia and other cancers in the children of male workers at Sellafield

    International Nuclear Information System (INIS)

    This report presents two findings of the U.K. Health and Safety Executive study group responsible for examining the conclusions of the Gardner Report that ''the raised incidence of leukaemia particularly, and non-Hodgkin's lymphoma, among children near Sellafield was associated with paternal employment and recorded external dose of whole body penetrating radiation during work at the plant before conception''. The HSE report is divided into three:- the Case-only study and the Radiation Dose study, concerned with the 11 case fathers who had worked at Sellafield. The third part, the Case-control study, is an epidemiological study which seeks to identify all cancer cases diagnosed before the age of 25, where the children concerned had been born in West Cumbria to fathers who were Sellafield employees. The search included the whole country from January 1980 to September 1989. (UK)

    This Scheme defines the organisation and procedures available should there be an accident at the Sellafield Site which results in, or may result in, the release of radioactive material, or the generation of a high radiation field, which might present a hazard to employees and/or the general public. Several categories of emergencies on the Sellafield Site are mentioned; a building emergency which is confined to one building, a Site emergency standby when the effects of a building emergency go outside that building, a Site emergency alert (District Emergency Standby) when a release of activity affects Site operations and could have serious Site effects and a District Emergency Alert when a radioactivity release may interfere with the normal activity of the General Public. A Drigg Emergency Standby situation would operate similarly at the Drigg Site. The detailed arrangements and responsibilities of appointed personnel are set out in this manual. (UK)

    British Nuclear Fuel Limited (BNFL) operate the United Kingdom's spent-fuel receipt, storage, and reprocessing complex at Sellafield. Spent fuel from graphite-moderated CO 2 -cooled Magnox reactors has been reprocessed at Sellafield for 22 yr. Spent fuel from light water and advanced gas reactors is stored pending reprocessing in the Thermal Oxide Reprocessing Plant currently being constructed. The range of knowledge and skills needed for plant operation, construction, and commissioning represents a formidable training requirement. In addition, employees need to be acquainted with company practices and procedures. Computer-based training (CBT) is expected to play a significant role in this process. In this paper, current applications of CBT to the filed of nuclear criticality safety are described and plans for the immediate future are outlined

    2012-01-01

    The Sellafield site in North West England is one of the oldest and largest nuclear sites in the world, with a 70 year industrial history of processing and power generation. At certain points in time this industrial activity has affected the quality of land on parts of the site and one of the main tasks for Sellafield Ltd is to understand and control the legacy of ground contamination to ensure protection of the workforce, the public and the environment. Sellafield Ltd has recently completed a multi-million Pound investigation of the most complex part of the site in order to understand the impact of the various known and potential sources of contamination. The constraints of working in a challenging operational environment required both the use of tried and tested approaches and experimentation with innovative techniques. As experience was gained during implementation of the project, the characterisation plan was evolved and adapted to ensure a successful outcome. The presentation will outline the role and importance of characterising land and groundwater at Sellafield, explain how the site investigation strategy and techniques were designed to meet the challenge and describe the performance of the investigation in practice. It will conclude with a summary of how the results will be used to better support ongoing safety and environmental management and to aid the development of strategy and planning for the future.

    Full text: In The Lancet (23 October 1999), Dr Louise Parker and colleagues from the Departments of Child Health and Statistics, University of Newcastle upon Tyne, UK, report the findings of a new study on stillbirths among offspring of male radiation workers at Sellafield. By linking the birth registration and stillbirth records in Cumbria from 1950 to 1989 to the database of workers at Sellafield, Dr Parker's team examined the stillbirth risk according to the father's exposure to radiation before conception of the child. From the birth documents of 248 097 livebirths and 3715 stillbirths, the team identified 130 stillbirths and 9078 livebirths to wives and partners of male radiation workers employed at Sellafield. Lifetime exposure, and that in the 90 days before conception, was derived from annual-exposure summaries for each worker. Exposures recorded on individual film badges for the fathers of each stillborn child and for four matched controls were also examined. The researchers found that although, as a group, babies of radiation workers were not more likely to be stillborn than babies of other Cumbrian fathers, there was an increased risk of stillbirth with increasing exposure of a father to external radiation. Although confounding factors also associated with stillbirth, such as whether the mother smoked, cannot be completely excluded, the researchers state that 'extensive checks confirmed that the statistical models were a good fit to the data and there was no statistical evidence of unmeasured factors'. However, the researchers are cautious in drawing any conclusions regarding causality. In the Commentary given in The Lancet, Hazel Inskip from the University of Southampton advises that the possible risk of stillbirth should be kept in perspective, and comments that 'there is no obvious mechanism for the association', but does concede that 'the greater increase in risk for stillbirths with neural-tube defects is at least focused on a more specific disorder

    1996-01-01

    Since 1983 British Nuclear Fuels plc (BNFL) at Sellafield has been actively involved in the decommissioning of its old plant, with 7 projects being fully completed, 6 projects in the practical phase, and 12 currently in the planning design and strategy studies phase. These projects vary from the dismantling of a single large alpha-contaminated glove box to the decommissioning of an entire 11-story building housing redundant reprocessing facilities. This paper provides an overview of the facilities involved and highlights the criticality issues that have been addressed for safety to support the decommissioning activities

    Sellafield Product and Residue Store (SPRS) is a new facility that has been constructed on the site of Sellafield. The design work started in early 2001 and active commissioning commenced with the introduction of the first nuclear material which arrived in the building early 2011. The store has been designed for the long term storage of Plutonium product (PuO2) from Thorp and Magnox, MOX residue powder from Sellafield MOX Plant (SMP) as well as pellet, powder or granular PuO2 residues from the older stores on the Sellafield site. This paper describes the application of Safeguards By Design commencing at the early design stage based upon the Safeguards Approach to be applied by DG ENER at the Sellafield Product and Residue Store (SPRS). The approach had been developed based upon the requirements for implementing Commission Regulation 302(2005) and the technical measures to be implemented in order to meet Article 77(a) of the Euratom Treaty. In order to meet these requirements a close dialogue was established between the different interested parties and the design team for the installation of instrumentation with associated cabling in order to implement the agreed safeguards measures. Early contacts at the design stage facilitated the inclusion of installed safeguards supplied instrumentation into the overall design and facility construction. The equipment and cabling supplied by Euratom was incorporated into the planning and construction phases. This ensured that upon plant completion the safeguards tools were commissioned and ready for the verification of the first nuclear material to be introduced into SPRS. Detailed discussions at the early stages of the design phase raised the profile of nuclear material safeguards and made certain that the necessary instrumentation infrastructure was incorporated into the plant infrastructure.

  7. The wide range in-core neutron measurement system used in the Windscale AGR concluding experiments

    Goodings, A.; Budd, J.; Wilson, I.

    1982-06-01

    The Windscale AGR Concluding Experiments included a comparison of theoretical and experimental power transients and required measurements of neutron flux as a function of position and time within the reactor core. These measurements were specified to cover as wide as possible working range and had to be made against the in-core gamma background of up to 4 x 10 7 R(hr) - 1 . The detectors were required to operate in special, channels cooled by reactor inlet carbon dioxide and the overall system needed a response time such that it could follow transients with doubling times down to 2s with an accuracy of 2 or 3%. These problems were solved by the use of gas ion fission chambers operating in the current fluctuation or Campbelling mode with unusually low filling pressures and fitted with special trilaminax mineral insulated cables. Ten detectors were built and nine were installed in the reactor, three in each of three special stringers at different radial positions. The paper describes the specification against which this system was built, the design process for the detectors, and commissioning experiments together with some of the problems which were encountered.

    British Nuclear Fuels plc undertakes a full range of fuel cycle services and is committed to an open-door policy in explaining its operations of the public; for which its Visitor's Centre at Sellafield is the flagship. The existing Centre was opened in 1988 and replaced an earlier, smaller, facility. In total, more than 1 000 000 visitors have been welcomed to Sellafield and the Site is now recognized as the largest tourist attraction in the region. This creates a high level of responsibility to the local area, to which Sellafield responds through its many community and education based projects. (author)

    As part of the extension and improvement plans for the British Nuclear Fuels Ltd reprocessing facilities at Sellafield, three Allen diesel engines have been installed for essential standby duty. They are 16-cylinder V-form engines with a continuous rating of 2,832 bhp and drive a 2000kW 11,000 volt 3 phase 50Hz salient pole synchronous alternator at 750r/min. They are arranged for running in parallel and with the public electricity mains supply and are also controlled to operate as standby in the event of mains failure. To prevent radioactive contamination from the atmosphere, primary and secondary air filtration has been supplied for each engine. Other operational facilities and safeguards are mentioned and the cooling system described. (U.K.)

    Individual (critical group) doses resulting from liquid discharges from the British Nuclear Fuels Limited (BNFL) Sellafield Works have been derived in a form normalised to unit radionuclide discharge rates. This has been done for the purpose of providing a basis for predicting doses in the event of nuclear fuel from a future Sizewell 'B' power station being reprocessed. These doses would have to be reviewed in the light of prevailing circumstances at the time when the actual discharges are known. (author)

    Studsvik have been incinerating Low Level Waste (LLW) at its licensed facility in Sweden since the mid-1970's. This process not only enables the volume of waste to be significantly reduced but also produces an inert residue suitable for final disposal. The facility has historically incinerated only solid dry LLW, however in 2008 an authorisation was obtained to permit the routine incineration of LLW contaminated oil at the facility. Prior to obtaining the authorisation to incinerate oils and other organic liquids - both from clean-up activities on the Studsvik site and on a commercial basis - a development program was established. The primary aims of this were to identify the optimum process set-up for the incinerator and also to demonstrate to the regulatory authorities that the appropriate environmental and radiological parameters would be maintained throughout the new process. The final phase of the development program was to incinerate a larger campaign of contaminated oil from the nuclear industry. A suitable accumulation of oil was identified on the Sellafield site in Cumbria and a commercial contract was established to incinerate approximately 40 tonnes of oil from the site. The inventory of oil chosen for the trial incineration represented a significant challenge to the incineration facility as it had been generated from various facilities on-site and had degraded significantly following years of storage. In order to transport the contaminated oil from the Sellafield site in the UK to the Studsvik facility in Sweden several challenges had to be overcome. These included characterisation, packaging and international transportation (under a Transfrontier Shipment (TFS) authorisation) for one of the first transports of liquid radioactive wastes outside the UK. The incineration commenced in late 2007 and was successfully completed in early 2008. The total volume reduction achieved was greater than 97%, with the resultant ash packaged and returned to the UK (for

These measurements were specified to cover a working range as wide as possible and had to be made against the in-core gamma background of up to 4 x 10 7 R(hr) - 1 . The detectors were required to operate in special channels cooled by reactor inlet CO 2 and the overall system needed a response time such that it could follow transients with doubling times down to 2s with an accuracy of 2 or 3%. These problems were solved by the use of gas ion fission chambers operating in the current fluctuation or ''Campbelling'' mode. Their neutron to gamma sensitivity ratio was optimised by the use of unusually low filling pressures and they were fitted with special ''trilaminax'' mineral insulated cables to minimise the effects of electrical interference at the 100 kHz channel centre frequency. Ten detectors were built and nine were installed in the reactor, three in each of three special stringers at different radial positions. All were processed and tested for operation at 350 deg. C and their fissile coatings (430 μg cm - 1 of natural uranium) were matched to give individual neutron sensitivities with a population spread better than +- 6% about the mean. The mean absolute sensitivities were determined to about +- 5% against manganese foils in the NESTOR reactor at AEE Winfrith. The detectors were complemented by special signal processing channels which provided current fluctuation sensitivity and appropriate output signals to the experiment data acquisition system. These channels also permitted dc measurement of chamber current for more precise flux determination near reactor full power

  14. Spent fuel surveillance at BNFL, Sellafield Nuclear Reprocessing Plant

    Addison, C.W.E.

    1988-01-01

    A wide range of irradiated nuclear fuels are stored in ponds in BNFL, Sellafield, UK, prior to reprocessing. Magnox fuel from the first UK power generating reactors has been stored and reprocessed since the mid 1950's, and stocks of irradiated AGR (Advanced Gas-cooled Reactor) and Water Reactor fuels are increasing prior to the start of reprocessing oxide fuel in the THORP (Thermal Oxide Reprocessing Plant) facility in the early 1990's. The methods of surveillance for each type of fuel are described. Underwater visual examination in ponds and more detailed examination in shielded caves are carried out. Limited surveillance is necessary for Magnox fuel as storage periods are short. For AGR fuels with longer storage periods the retrieval and element breakdown are described, followed by detailed metallurgical examination of pins and element components. The effect of water chemistry on corrosion performance of irradiated AGR fuel during pond storage is illustrated. The methods of confirming satisfactory water storage of water reactor fuel are outlined. The major results of surveillance of each type of fuel are summarised. The organisation of the work programmes is given. The paper concludes that, mainly through monitoring and surveillance, backed by experimental programmes optimum storage regimes have been developed for the various types of fuel, consistent with planned storage periods prior to reprocessing.

    1982-01-01

    The safeguard requirements of a nuclear fuel reprocessing plant place unique constraints on a designer which, in turn, affect the scope for the exercise of water economy. These constraints are examined within the context of the British Nuclear Fuels Limited reprocessing plants at Windscale and indicate the scope for water conservation. The plants and their design principles are described with particular reference to water services and usage. Progressive design development is discussed to illustrate the increasing importance of water economy. (author)

    1993-01-01

    In the early eighties British Nuclear Fuels' Sellafield plant was hit by two events. An unscheduled release of radioactivity onto the beaches near Sellafield attracted headline news, although it subsequently became clear that the risk of any resulting harm to the public was extremely remote. There was inevitably a great deal of adverse publicity. Local tourism levels were said to have fallen during the next twelve months, and there were many calls for Sellafield's operations to be restricted or stopped. Something clearly had to be done. And so much has been done that during the last seven years, Sellafield, Britain's largest nuclear fuel recycling plant and the country's largest nuclear facility, has become a major tourist attraction. This rather strange development began in 1984 with a major review of our PR strategy. Alternative strategies were researched as a result of which a strategy was developed to help build credibility through an open door/open information policy and inviting the public to visit Sellafield and see for themselves. As a part of the strategy a public relations programme, including a major national advertising campaign on television and in the press, began in 1986 and has played a major part in developing visitor numbers to Sellafield ever since. From 29,000 in 1985, to 65,000 in 1986, to 104,000 in 1987. In fact the number of visitors increased so dramatically in 1987 that the company decided to replace the overrun exhibition centre with a new 5 million pound Visitors Centre which, opened in 1988, has over the years become the flagship for our open door/open information strategy

    strategy process is more complete. These actions represent opportunities to find out what works an d what needs further fine-tuning and also to establish the type of conditions necessary for fuller-scale implementation. A further opportunity exists in that all of our knowledge management activities are being developed within the EFQM Knowledge Management Framework (2005) that explicitly ties knowledge management activities into the EFQM Business Excellence Model. The KM Framework has five enablers: Leadership, Partnerships and Resources, Policy and Strategy; Processes and People. It was developed following studies in 1996 and 2002 undertaken on behalf of EFQM (EFQM/CIBIT, 2002). Such a Framework will enable BNG Sellafield to benchmark against other organisations using the Framework in the medium-term future. Its benefits also include a range of indicators mapped against the enablers that can be selected for measurement depending on the level of knowledge management maturity at any given point in time along our journey. Future developments include the establishment of a National Nuclear Knowledge Forum that facilitates the sharing of knowledge, good practise and promotes effective Knowledge Management between all sites in the UK. Our conference paper will be articulate the range of challenges and opportunities more fully and provide some lessons learned at that point in the journey. (author)

The commissioning of BNFL's fuel handling plant was also discussed. (UK)

  19. Sellafield waste radionuclides in Irish sea intertidal and salt marsh sediments.

    Science.gov (United States)

    Mackenzie, A B; Scott, R D

    1993-09-01

    Low level liquid radioactive waste discharges from the Sellafield nuclear fuel reprocessing plant in north west England had generated environmental inventories of about 3 × 10(16) Bq of(137)Cs, 6.8 × 10(14) Bq of(239,240)Pu and 8.9 × 10(14) Bq of(241)Am by 1990. Most of the(239,240)Pu and(241)Am and about 10% of the(137)Cs has been retained in a deposit of fine marine sediment close to the discharge point. The quantities of radionuclides discharged annually from Sellafield decreased by two orders of magnitude from the mid-1970s to 1990 but estimated critical group internal and external exposure decreased by less than one order of magnitude over this period. This indicates that during the period of reduced discharges, radionuclides already in the environment from previous releases continued to contribute to the critical group exposure and highlights the need to understand processes controlling the environmental distribution of the radionuclides.Redistribution of the contaminated marine sediment is potentially of major significance in this context, in particular if it results in transport of radionuclides to intertidal areas, where contact with the human population is relatively likely.A review is presented of published work relating to Sellafield waste radionuclides in Irish Sea sediments. Data on temporal and spatial trends in radionuclide concentrations and activity ratios are collated from a number of sources to show that the dominant mechanism of radionuclide supply to intertidal areas is by redistribution of the contaminated marine sediment. The implications of this mechanism of supply for trends in critical group radiation exposure are considered.

    The raised incidence of leukaemia, particularly, and non-Hodgkin's lymphoma among children near Sellafield was associated with paternal employment and recorded external dose of whole body penetrating radiation during work at the plant before conception. The association can explain statistically the observed geographical excess. This result suggests an effect of ionising radiation on fathers that may be leukaemogenic in their offspring, though other, less likely, explanations are possible. (author)

    This paper describes the Public Inquiry opened on 14 June 1977 concerning extenssion of the Windscale plant and the events preceding it. Four issues were considered: the implications of the proposed development for public safety; those for other aspects of the national interest; those of plant construction and operation for the environment: the measures that could be adopted under existing U.K. legislation, particularly under the Radioactive Substances Act 1960 to control waste disposal, and under the Nuclear Installations Act 1965 to provide for the safety of operations, and finally, other implications for the locality.

  2. The Safety Assessment of Long term Interim Storage at Sellafield

    2014-01-01

    The Sellafield site comprises a wide range of nuclear facilities, including operating facilities associated with the Magnox reprocessing programme, the Thermal Oxide Reprocessing Plant (THORP) and a range of waste treatment plants. The operational life of some of the site facilities currently extends to 2120, requiring the retrieval, treatment, consolidation and safe extended storage of a variety of radioactive materials. Sellafield has utilised its existing safety assessment processes to inform and prioritise studies into beyond design basis events and resilience evaluation required following Fukushima by UK regulators and industry bodies such as WANO. There are significant differences between NPPs, for which the ENSREG 'stress tests' were originally intended, and the Sellafield site which is instead centered around two reprocessing facilities (Magnox and THORP), with a supporting infrastructure of waste processing and storage facilities, coupled with a legacy of high hazard older facilities. In the former case the consequences of a catastrophic failure are promptly realised, leading to significant problems such as fuel failure / meltdown in AGRs and LWRs respectively in the event of complete loss of cooling. At Sellafield, the processes are carried out at comparatively low temperatures and pressures with relatively low rates of change following any loss of cooling. Instead the consequences of catastrophic failure at Sellafield are more directly related to the very large inventories of radioactive materials, including high level liquid wastes and unprocessed fuels, present in specific plants and to the condition of the ageing assets, holding legacy wastes. The paper will consider how a number of analysis techniques have been used to establish a safety case for fault and accident conditions, i.e. design basis analysis (DBA), probabilistic safety analysis (PSA) and severe accident analysis (SAA) DBA is focused on the key safety measures for those initiating faults

    In accordance with company policy agreed to in April 1986, graduate new entrants to British Nuclear Fuels (BNFL) Sellafield join a management trainee/appraisal scheme. The purpose of this scheme is that while doing a real job, the trainee should undergo structured training and be given the opportunity to develop both personally and professionally. As part of this scheme, each trainee has a structured training program that is devised to fulfill the requirements of the individual, the department, the site and the professional body to which the trainee aspires. This paper outlines the management trainee training/appraisal system and the structured training program that is used to train criticality safety assessors at BNFL Sellafield

    Since July 1986 a commercial advertising campaign has been encouraging people to visit the BNFL plant at Sellafield to find out for themselves what goes on there. As a result it is now a flourishing tourist attraction. Casual visitors can visit the Ehibition Centre and go on a bus tour of the site lasting an hour. Pre-booked visitors can go on a five hour tour which looks at the processes in detail. The object is to open up the site so that people can be better informed and can make up their minds about the merits or otherwise of Sellafield, and nuclear power in general, with a knowledge of the facts.

    An Instron model 1273 servo-hydraulic machine has been installed within a lead-shielded cell at Windscale in order to provide a facility capable of performing a wide range of mechanical tests on nuclear reactor structural materials and fuel assembly components. This particular type of machine was chosen because it has design features associated with the load frame, location of the actuator and adjustment and clamping of the cross-head that are especially well suited to remote operation within a shielded cell. The design of the testing facility is described and the programmes of work that have been completed over the past 11/2 years of operation are reviewed. (author)

  6. Measurement of sulphur-35 in the coolant gas of the Windscale Advanced Gas-Cooled Reactor

    1978-03-01

    Sulphur is an important element in some food chains and the release of radioactive sulphur to the environment must be closely controlled if the chemical form is such that it is available or potentially available for entering food chains. The presence of sulphur-35 in the coolant gas of the Windscale Advanced Gas-Cooled Reactor warranted a study to assess the quantity and chemical form of the radioactive sulphur in order to estimate the magnitude of the potential environmental hazard which might arise from the release of coolant gas from Civil Advanced Gas-Cooled Reactors. A combination of gas chromatographic and radiochemical analyses revealed carbonyl sulphide to be the only sulphur-35 compound present in the coolant gas of the Windscale Reactor. The concentration of carbonyl sulphide was found to lie in the range 40 to 100 x 10 -9 parts by volume and the sulphur-35 specific activity was about 20 mCi per gramme. The analytical techniques are described in detail. The sulphur-35 appears to be derived from the sulphur and chlorine impurities in the graphite. A method for the preparation of carbonyl sulphide labelled with sulphur-35 is described. (author)

  7. Development of a Hydrogeological Model of the Borrowdale Volcanics at Sellafield

    1997-01-01

    Full Text Available This work has arisen out of recent developments within the radioactive waste research programme managed by Her Majesty's Inspectorate of Pollution, UK (HMIP*, to develop an integrated flow and transport model for the potential deep radioactive waste repository at Sellafield. One of the largest sources of uncertainty in model predictions, is the characterisation of the hydrogeological properties of the underlying strata, in particular, of the Borrowdale Volcanic Group (BVG within which the repository is to be located. Analysis of the available borehole data (that released by the proponent company, Nirex, by December 1995 for the BVG formation has indicated a dual regime consisting of flow within faults and flow within the matrix (or an equivalent porous medium containing micro-fractures. Significant relationships between permeability, depth and the presence and orientation of faults have been identified; they account for a variation of up to 6 orders of magnitude in mean permeability measurements. This can be explained in part by the effect of the orientation of the current maximum principal stress directions within the BVG: however, it is likely that permeability is also dependent on the existence of fracture families, which cannot be effectively identified from the data currently available. These analyses have enabled considerable insight to be gained into the dominant features of flow within the BVG. The conceptual hydrogeological model derived here will have a significant effect on the outcome and reliability of future radionuclide transport predictions in the Sellafield area.

    Methods are described of sampling and examining carbon deposits on fuel cladding in the Windscale advanced gas-cooled reactor. Deposition is observed on fuel cladding in both the reactor core and experimental loops in carbon dioxide coolants containing various amounts of carbon monoxide and methane. Deposit distribution over the cladding surface indicated that nucleation is dependent on local surface conditions. Microscopical examination showed that deposit thickness increases by carbon filament growth into the coolant gas stream and that the process can be markedly influenced by metallic impurities. There is evidence that nickel can play a particularly significant role in deposition in loop experiments but similar effects have not been observed in the reactor core. (author)

  9. Development of techniques to dispose of the Windscale AGR heat exchangers

    1991-01-01

    In a gas-cooled nuclear power plant the gas side of the heat exchanger tubes becomes contaminated with radioactive deposits carried from the reactor in the coolant stream. In order to dispose of the heat exchangers in the safest and most cost-effective way during plant decommissioning, the deposits have to be removed. In situ chemical decontamination is considered to be the only viable method. This paper describes the research and development of chemical decontamination methods for the Windscale AGR heat exchangers, and the testing of a selected method on an in situ superheater. The research involved characterization of tube corrosion and radioactivity deposits, laboratory testing of chemical reagents on actual tube samples, and the provision and operation of a plant to apply the selected reagent. Disposal of radioactive effluent is an important consideration in chemical decontamination and in the present case was the major factor in determining the process

  10. The regulation of technetium-99 discharges at Sellafield

    International Nuclear Information System (INIS)

    Mayall, A.

    2002-01-01

    The reprocessing of spent Magnox fuel at BNFL Sellafield produces a liquid waste concentrate containing technetium-99 and other, more radiotoxic, radionuclides such as plutonium and americium. The concentrate is known as medium active concentrate (MAC). Prior to 1981, MAC was discharged to sea untreated after several years' storage, during which short-lived radionuclides underwent radioactive decay. In the early 1980s, discharges of MAC were suspended and it was retained in storage tanks, pending the construction of a plant to remove the radionuclides of greatest radiological concern (these did not include technetium- 99). The Enhanced Actinide Removal Plant started operation in 1994 and began to clear the backlog of stored waste MAC, as well as current arisings from Magnox reprocessing. As a consequence technetium-99 was once more discharged to sea. Subsequently, concentrations of this radionuclide in the marine environment increased. In particular, there was a significant increase in the concentration of technetium-99 in lobster in the Irish Sea. An increase in technetium-99 has also been detected at locations far distant from Sellafield, e.g. in Scandinavian coastal waters, albeit at very low concentrations. This dispersal of technetium- 99 throughout the Irish Sea and further afield has therefore caused concern, although the radiological impact is low. This paper examines the nature and source of the technetium-99 in sea discharges at Sellafield and the levels of past and current discharges as well as their impact. It goes on to describe the Environment Agency's recent proposals on the future regulation of technetium-99 discharges and how these should lead to substantial reductions in not only technetium-99 discharges, but also of other radionuclides such as caesium-137 and strontium-90.

    Nirex is responsible for providing and managing a national facility for solid intermediate-level and low-level radioactive waste. Geological and hydrogeological investigations have been in progress at Sellafield in west Cumbria since 1989 aimed at determining whether or not the site is suitable for such a deep repository. Geological investigations have included the drilling of 20 deep boreholes with over 20 000 metres of drilling, together with almost 2000 line kilometres of seismic surveys and over 8000 line kilometres of airborne geophysical surveys. Hydrogeological testing and groundwater sampling and testing have provided additional information on the ground conditions at the site. (author)

    UK Nirex is the company charged with finding a suitable site for the underground disposal of radioactive waste in the United Kingdom. Since 1991, Nirex has concentrated its investigation work at a site owned by British Nuclear Fuels Ltd near Sellafield. Planning permission was sought in 1994 for the development of an underground Rock Characterisation Facility at the site. A public Planning Inquiry began in September 1995. A wide range of scientific and technical objections were put by expert witnesses against the Nirex proposal. These witnesses were co-ordinated by three Objecting Organisations - Cumbria County Council, Friends of the Earth and Greenpeace. Their written evidence is presented in the 34 chapters of this book and separate abstracts have been written for each contribution. (UK)

  14. The Nirex Sellafield site investigation: the role of geophysical interpretation

    International Nuclear Information System (INIS)

    Muir Wood, R.; Woo, G.; MacMillan, G.

    1992-01-01

    This report reviews the methods by which geophysical data are interpreted, and used to characterize the 3-D geology of a site for potential storage of radioactive waste. The report focuses on the NIREX site investigation at Sellafield, for which geophysical observations provide a significant component of the structural geological understanding. In outlining the basic technical principles of seismic data processing and interpretation, and borehole logging, an attempt has been made to identify errors, uncertainties, and the implicit use of expert judgement. To enhance the reliability of a radiological probabilistic risk assessment, recommendations are proposed for independent use of the primary NIREX geophysical site investigation data in characterizing the site geology. These recommendations include quantitative procedures for undertaking an uncertainty audit using a combination of statistical analysis and expert judgement. (author)

    1984-01-01

    A decision to decommission the Windscale Advanced Gas Cooled Reactor was taken shortly after reactor shutdown in 1981. The fuel has now been discharged and the decommissioning programme will last about 10-12 years. The paper describes the programme and objectives and deals with methods of handling and disposing of the radioactive waste material. The main new facility required is a Waste Packaging Building adjacent to the existing reactor in which the waste boxes will be filled, active waste encapsulated in concrete and the boxes cleaned, swabbed and monitored to comply with IAEA transport regulations. The handling machine concept and features are described. The assaying and packaging of the waste material, the control of box movement and the process of concrete encapsulation is described. The paper concludes with a description of the development programme to support the Project. The tasks include a study of cutting techniques, production and control of dust and smoke, viewing and lighting methods, filtration, decontamination and fixing of contamination

  16. The Sellafield controversy: The state of local attitudes

    1987-01-01

    The authors have presented some of the key findings of a local survey, attempted to provide plausible interpretations of them, and illustrated some of their relevance in a contemporary policy context. The authors recognize that they have touched upon only the surface of the complex of factors which generate people's attitudes and opinions. BNFL may be assured of a bedrock of local support; its position is under no serious threat or overwhelming pressure from local communities. As the authors see it, the need now is to improve the basis on which a more thorough assessment of local attitudes might be made. A priority in a more thorough assessment would be to adopt a different structure to the questionnaire - one which would allow respondents greater freedom of expression and, in turn, provide data from which it would be possible to gain deeper insight into the more complex issues of attitudes and opinion formation. A more rigorous sampling method might also be adopted, as well as pursuing a longitudinal approach to research in order to achieve a fuller understanding - studying the Sellafield case as it develops and the effect of related events

    In 1983, a television programme identified a striking cluster of childhood leukaemia in the coastal village of Seascale, adjacent to the Sellafield nuclear complex in England. Excesses of childhood leukaemia near certain other nuclear installation in Britain were later reported during the 1980s. Detailed radiological investigations demonstrated that radiation exposures from discharged radioactive material were most unlikely to be the cause of these excesses and no serious deficiencies in these assessments have been discovered despite exhaustive searches. In 1990, a report was published suggesting that occupational radiation exposure of men before the conception of their children could be responsible for the Seascale cluster. Extensive research has not supported a causal link between paternal preconceptional radiation dose and childhood leukaemia, and the idea that radiation exposure of fathers materially increases the risk of leukaemia in offspring and could account for the clusters has now effectively been abandoned. In contrast, evidence has mounted that childhood leukaemia has an infectious basis and that unusual population mixing increases the risk of the disease. It now seems that population mixing is the explanation for the excesses of childhood leukaemia near nuclear sites and at other locations with no enhanced exposure to radiation. (orig.) [de

    Full Text Available The Sellafield nuclear plant is a 3 km2 site in north-west Cumbria, England, with a long and distinguished history of nuclear power generation, reprocessing and waste storage—with a current working emphasis on decommissioning and clean-up. Important to this safe, efficient and complete remediation of the site, routine monitoring is essential in a wide range of on-site environments and structures to attain: (i accurately map the evolving distribution of radiation with the best possible accuracy (sensitivity and spatial resolution; in addition to (ii the contributing radionuclide species and therefore the radiological and chemo-toxicity risk. This work presents the trial deployment of an unmanned aerial vehicle equipped with a lightweight radiation detection system as a novel tool for the assessment of radioactivity at a number of test-sites on the nuclear licenced site. Through the use of this system, it was possible to determine the existence of anthropogenically present radiation at selected facilities. Such a system has been proven to be highly accurate (spatially and precise (attribution of contamination species observed within the challenging site environments, capable of measuring and mapping contamination over both high and low dose-rate areas.

    The present investigations in the vicinity of the Sellafield potential repository zone have provided data on groundwater pressure and salinity to a depth of some 2000 m, for a section extending from the hills to the east of the zone, to the coast. As part of the process of demonstrating the suitability of the site for a deep repository, work has been undertaken to reconcile these observations of pressure and salinity with an understanding of the hydrogeology of the site. It is considered possible that the long glacial history of the site may in part be responsible for present observations. This work documents some preliminary studies to determine the possible magnitude of such glacial effects. 4 refs, 2 figs.

Since 1991, Nirex has concentrated its site investigation work at Longlands Farm which is owned by British Nuclear Fuels Ltd and is near their Sellafield site. Planning permission was sought for the development of an underground Rock Characterisation Facility (RCF) at the site in 1994. A public Planning Inquiry began in September 1995. A wide range of scientific and technical objections were put by expert witnesses against the Nirex Proposal. These witnesses were co-ordinated by three Objecting Organisations - Cumbria County Council, Friends of the Earth and Greenpeace. Their written evidence is presented in this book. The grounds of the objections include: the inadequacy of the methodology adopted by Nirex for site selection and investigation; The unsuitability of the site geology, hydrology and geochemistry; that construction of the RCF would destroy the data essential to deciding site suitability; that the RCF would provide a conduit for the release of radioactivity; a number of features in the Nirex risk assessment that would lead to an underestimation of the potential risks of a repository at this site.

    Tensioned steel wires are widely used in civil engineering structures. They can, however, be vulnerable to corrosion. To reduce the probability of corrosion, sophisticated protection systems are used. Extensive inspection and maintenance regimes are also able to be implemented to confirm that the design strength is available over the lifetime of the wires. These regimes include tests to confirm the condition of post-tensioning cables or stay cables, which can verify the overall performance of the structure. This paper presents a technology to detect and locate wire failures in tensioned cables for use on a wide variety of pre-stressed or post tensioned structures, where they have increased confidence in the structures and reduced maintenance costs. This methodology is the continuous acoustic monitoring technology which uses distinctive acoustic characteristics of wire breaks to separate them from other acoustic activity on the structure. With a combination of instrumentation, data acquisition and data management, it is possible to identify a wire break event, as well as to locate the position and time of the failure. Over 10 years' experience of acoustic monitoring for this application with several independent and blind tests, shows that even in noisy environments the acoustic monitoring method is able to identify and locate wire breaks in fully grouted and partially grouted tendons, stay cables and suspension cables. The design (number of sensors and location) is very important to be sure to cover all wires in the structure. This paper explains the principles of the systems and shows them in practice on a case study of a project in a pre-stressed roof structure of an active tank farm at Sellafield site

    Radiological dose implications for consumers of wild foods around Sellafield have been assessed. Habits were surveyed from 72 households, mostly within a few kilometres of Sellafield. A few people were included who lived further away but collect wild foods close to Sellafield. Dose estimates were based on measured gamma emitters, as well as 239 Pu, 241 Am, 14 C and 129 I in selected samples. In all cases, doses were dominated by 137 Cs. One infant was identified who consumed wild food, giving an estimated effective dose of 0.3 μSv a -1 . In the age group 2 to 10 years a mean dose of 0.51 μSv a -1 , and a maximum of 2.8 μSv a -1 , were estimated. Intakes by adults were higher and resulted in more radiologically significant doses. The extreme individual received a dose of 32 μSv a -1 largely due to consumption of honey that included contributions from the Chernobyl accident, and hedgerow fruits. This is comparable to doses to the critical group for consumption of conventional agricultural produce close to the Sellafield site. The 97.5th percentile dose, for all age groups of consumers taken together, was 16.6 μSv a -1 , or 6.2 μSv a -1 if the contributions from Chernobyl are excluded. Considering the contributions from different foods to the whole group of 181 wild food consumers, the rank order is honey, blackberries and venison. (author)

  9. How an integrated change programme has accelerated the reduction in high hazard nuclear facilities at Sellafield - 59014

    2012-01-01

    For over five decades the Sellafield Site has been central to the UK's nuclear programme. Sellafield Ltd is managed by NMP (Nuclear Management Partners), a consortium of URS, AMEC and AREVA and is focussed on the decommissioning of historical facilities. When the activity of Decommissioning commenced in the late 1980's the site focus at that time was on commercial reprocessing and waste management. Now through the implementation of an integrated company change programme, emphasis has shifted towards accelerated risk and hazard reduction of degraded legacy plants with nuclear inventory whilst ensuring value for money for the customer, the Nuclear Decommissioning Authority (NDA). This paper will describe the management approach that is being taken and the planning tools that are being applied by the Site owners in delivering an integrated change programme across the Decommissioning Directorate. The paper will explain how the management approach to change uses Peer Assist, Rapid Improvement Events, Organisational Review Self Evaluation, Value Stream Analysis and Accelerated Improvement Events as improvement tools. Use of these has enabled down-sizing of the organisation, driven out hundreds of man day efficiencies within the maintenance and asset management areas, improved the management of spares reducing annual costs by Pounds 1000's, improved Commercial practices by fast tracking the preparation of invitations to tender for critical contracts, rolled back radiological control areas and enabled quicker access to the work-face at a reduced cost. This paper will explain in detail how the Decommissioning Directorate Programme Office has implemented planning tools such as governance, identification of opportunities, benefit evaluation and prioritisation and sanction of the optimum improvements and how through the use of a balanced scorecard, delivery of the improvements has been measured ensuring that the targets are met. Finally, the paper will discuss how the

    2002-01-01

    This paper presents the method used by the UK Food Standards Agency (FSA) to assess the potential impact of proposed radioactive discharges from the Sellafield nuclear site on food and determine their acceptability. It explains aspects of a cautious method that has been adopted to reflect the UK government policy and uncertainties related to people's habits with regard to food production and consumption. Two types of ingestion doses are considered in this method: 'possible' and 'probable' doses. The method is specifically applied to Sellafield discharge limits and calculated possible and probable ingestion doses are presented and discussed. Estimated critical group ingestion doses are below the dose limit and constraint set for members of the public. The method may be subject to future amendments to take account of changes in government policy and the outcome of a recent Consultative Exercise on Dose Assessments carried out by FSA. Uncertainties inherent in dose assessments are discussed and quantified wherever possible

    Prior to 1984, the reported marine 14 C discharges from Sellafield were estimates: 0.2 TBq per annum from 1952 to 1969 and 1 TBq per annum until 1984 when measurements commenced. The relationship between the net excess 14 C activity in annually collected Nori (Porphyra umbilicalis) seaweed samples and the annual discharges (estimated and measured) implies that the discharges were not as constant as the estimates. Based on the relationship between post-1984 measured discharges and the excess 14 C in the seaweed, two simple empirical models were used to re-calculate the discharges between 1967 and 1984. Gamma-spectrometry measurements on the seaweed also indicate that Porphyra is a sensitive indicator of changes in discharge of other radionuclides, brought about by the introduction of new waste clean-up technologies within Sellafield.

    Public support for the nuclear industry appears to be growing in the UK at a time when environmental awareness is also prominent. Perceived advantages from nuclear power range from conservation of scare fossil reserves through to maintaining a worldwide technical competitiveness. Within the UK, the Sellafield Visitors Centre has proved to be a large tourist attraction, as well as successfully presenting information in a form that is easy to understand. (author)

    One of the best descriptions of Culture is 'how we do things around here'. In a stable organisation it is extremely difficult to change any type of culture, whether it is an operations, customer service or safety culture. To change culture one of two elements are essential. There must be either a significant external pressure felt by all in the organisation or a change in senior management, with authority to set a new direction for the organisation. BNFL had a unique opportunity through the commissioning and operation of the Thorp Reprocessing Plant at Sellafield to shape a new Safety and Operations Culture. Both the key elements for change were present. Thorp was a high profile flagship plant that had attracted multinational investment. It incorporated new technology. The workforce had volunteered to operate the plant. A strong senior management team was specially selected. The plant was being commissioned in an environment where there was significant opposition by 'anti nuclear' groups. It was essential to both BNFL and the wider international nuclear community that Thorp was commissioned and operated safely. A strong operating culture was developed with safety as the corner stone. The culture comprises three key components. Rigorous plant safety case and risk assessments before work commences and modifications to the plant occur; A high level of involvement by all levels of the workforce in both operations and safety matters; Strong supportive leadership which does not allow safety standards to be compromised and encourages open debate on how to improve. During commissioning and early operation of Thorp the robustness of the Safety and Operations Culture was demonstrated. On several occasions, despite intense commercial pressure, operations were halted until the situation was resolved both technically and procedurally. This paper describes how the Safety and Operations Culture was developed. The key factors for success include recruitment, team selection

    1999-01-01

    The current Nirex design concept for the disposal of intermediate-level and some low-level radioactive wastes in the UK involves emplacement in a cementitious repository deep underground. The Nirex Safety Assessment Research Programme includes a study of the sorption of radionuclides on geological materials, as sorption processes are important mechanisms for retarding radionuclides migrating from a repository. A site near Sellafield has been investigated to see if it is suitable. The potential host rock would be the Borrowdale Volcanic Group (BVG) which is comprised of tuffs characterised by low porosity and permeability. This paper gives an overview of studies of the sorption of actinides onto BVG rock and includes a description of experimental techniques in use at AEA Technology, the difficulties inherent in working with such intact rock samples, and the use of data from both crushed and intact-rock experiments. The main sorbing minerals in the BVG are discussed, along with perturbing influences such as the degradation products from organic materials in the wastes and highly alkaline porewater from the cementitious backfill.

    Nuclear cycle facilities, such as recycling plants, over the world differ in their design and operation history. Transferability of Learning From Experience (LFE), Best Practices and Decommissioning tools and techniques may not appear as relevant as it would be for a fleet of reactors. Moreover Regulatory, Economic and Social Drivers may differ from one country to another. Technical Drivers being comparable, AREVA and Sellafield Ltd (SL) have conducted various benchmarks and technical peer reviews to consider LFE from AREVA's Post-Operation Clean Out (POCO) and Decommissioning projects (such as UP2-400 on the La Hague site) and those performed for customers (such as CEA's UP1 on the Marcoule site). The intention is that Sellafield can benefit from AREVA experience and incorporate some recommendations in their own programmes. These reviews highlighted not only that investigation tools and methods as well as Decommissioning techniques are fully transferable, but also that strategic, technical and organizational key recommendations are applicable. 1. End-state definition (for each programme step) has a strong impact on POCO and Decommissioning scenarios. 2. A waste-driven strategy is essential for the overall programme cost and schedule management, and it avoids detrimental activities and short-term decisions made under pressure that may have negative impacts on the Programme. 3. Safety issues associated with POCO and decommissioning programmes are different from the commercial operations environment. 4. An extensive characterization plan (with physical and radiological surveys and active sampling) is essential to underpin the final POCO / decommissioning scenario and build a plant configuration baseline that will be updated as the decommissioning progresses. 5. Transition from operations to decommissioning requires a major change in culture; the organization must adapt to the new decommissioning environment. 6. Securing specific competencies, resources and

    The principal aim of this report is to assist the Committee of Petitions of the European Parliament in its consideration of Petition 393/95 brought by Dr. W. Nachtwey. The Petition expresses concerns about radioactive discharges from nuclear reprocessing plants at Sellafield in the UK and La Hague in France, and their possible adverse health effects. Six years after the Petition was introduced, the Petitioner main concerns remain relevant. This report concludes that reprocessing discharges are a valid matter for the Committee consideration. It also concludes that, on balance, the Petitioner's concerns over radioactive discharges from Sellafield and La Hague are justified. The report presents evidence and data on: 1) radioactive discharges from the Sellafield and La Hague sites; 2) resulting nuclide concentrations in environmental media including foodstuffs; 3) radiation doses from nuclide discharges to critical groups near the sites; 4) adverse health effects near the two sites; and 5) resulting collective doses from nuclide discharges. The report also examines a number of current issues in radiobiology concerning health effects from exposure to ionising radiation, in particular genetic and in utero effects. In addition, in accordance with contract specifications, the report examines other major factors that might influence future decision-making on reprocessing. It provides information on the legal framework, the operational history of the plants and the economic case for reprocessing compared with available alternatives for spent nuclear fuel management. The report also makes policy-related recommendations that take into account current knowledge and uncertainties in risk assessment and the availability of alternatives to reprocessing in spent fuel management.

    Recently, United Kingdom Nirex Limited has investigated a site near Sellafield, north-west England to assess its suitability as the potential location for a deep underground repository for the disposal of intermediate- level, and some low-level, solid radioactive waste. Groundwater flow at the site was simulated using a variety of computer codes, based upon conceptual models of the hydrogeological system. Chemical data for groundwaters aided the development of these conceptual models, and also provided a check upon the computer models' validity. Mineralogical information can be accommodated within the conceptual and theoretical framework. The results of the investigation are presented. (author)

    In this letter the author comments on K.E. Baverstock's case (1991) against the likelihood of a causal relationship between reported leukemia incidence and paternal radiation dose in the children of Sellafield workers, and emphasizes the desirability of devising experimental tests of the germ-cell line damage hypothesis as well as the evaluation of its plausibility. Particular reference is made to the role played by dose-rates and by the two-hit model for childhood acute leukemia. (Letter to the Editor)

    This report provides input data for TIME4 Version 2.0 which has been developed for use at Sellafield and Dounreay. This report presents a review of the available data on the disposition of tills and other glacial deposits and landforms in the regions around Sellafield and Dounreay. This information is supplemented by the use of satellite imagery which has allowed the delineation of glacial flowlines on a regional basis. The glacial data is used as a constraint for the modelling of ice sheet behaviour. The physical basis of the model used has been developed previously but is presented for reference in this report. Modifications, notably the use of a nested topographic grid to improve resolution around the site, are described. Output from the model includes ice-front position, relative sea-level, erosion and deposition and sub-glacial discharge as a function of time and position along a transect. Additional information relating to the surface slope of the ice sheet is also included. (Author)

    The inhabitants of coastal regions bordering the Irish Sea may be exposed to radionuclides, of Sellafield origin, through a variety of pathways. An assessment of the magnitude of these doses and the regional differences is presented in this report. The assessment has considered exposures arising from the seafood, beach, intertidal and sea-spray transfer pathways. The spatial differences in the doses received through each pathway and the future evolution of the doses are determined by the predicted difference in the behaviour of individual radionuclides in the Irish Sea. Difference in the degree to which radionuclides adsorb onto sediments give rise to characteristic patterns in which 137 Cs is more uniformly distributed than the actinides and in which 137 Cs responds to the decreasing discharge rate from Sellafield more readily than the actinides. Thus, pathways in which the dose depends on the concentrations of 137 Cs, such as external irradiation over beaches, show smaller regional differences than do pathways whose dose depends on the concentrations of actinides, such as the ingestion of molluscs. The 137 Cs-controlled pathways are predicted to decline in the future in response to discharge rates much more rapidly than the actinide-controlled pathways which are subject to the influence of remobilisation processes.

    National Nuclear Laboratory, in collaboration with the Australian Nuclear Science and Technology Organisation, is developing hot isostatic press (HIP) based ceramic technology for the immobilisation of a diverse range of wastes arising from nuclear fuel processing activities on the Sellafield site. Wasteform compositions have been identified and validated for the immobilisation of these plutonium containing wastes and residues in glass-ceramic and ceramic forms. A full scale inactive facility has been constructed at NNL's Workington Laboratory to support the demonstration of the technology. Validation of the inactive wasteform development using plutonium has been carried out at ANSTO's Lucas Heights facility. A feasibility study has been conducted to evaluate the construction and operation of a plutonium active pilot facility which would demonstrate the immobilisation of actual residues in the NNL Central Lab. This could form the basis of a facility to treat the plutonium wastes and residues in their entirety. The technology is being explored for the immobilisation of additional wastes arising on the Sellafield site taking advantage of the investment already made in skills and facilities. (authors)

    A flowsheet for a production plant has been worked out and the problems of designing a reliable production plant utilising it have been assessed. The properties of current glass compositions have been considered in relation to problems of permanent storage for periods of 800 to 1000 years and various storage proposals assessed. The performance of the preferred type of storage, i.e. dry storage in natural draught air-cooled vaults, has been estimated and consideration given to a number of variables affecting the optimum design. The design problems of a storage of the required life have been investigated in relation to suitable types of site and proposals made as to the types of construction to be used. Design work on tunnel loading facilities has been carried to the state of demonstrating feasibility. The capital costs and the economics of this type of waste storage have been investigated for unalloyed Magnox fuel and brief consideration given to alloyed and cermet fuels. Attention has been given to development problems of the whole system where they arise. (author)

  8. The distribution of gamma-emitting radionuclides in surface subtidal sediments near the Sellafield plant

    1988-08-01

    Detailed distributions of total gamma activity, 137Cs, 106Ru and 95Zr + 95Nb in surface seabed sediments near the Sellafield plant are presented. The results are derived from a towed seabed gamma-ray spectrometer survey in September, 1982. All the distributions are similar, with contours of equal activity parallel to the coast defining a 'ridge' of higher activity which is displaced northwards relative to the outfall. This pattern appears to be largely a response to the transport of particle-associated radioeffluent modified in places by the type of seabed sediment present. At greater distance from Sellafield, the uptake of nuclides from solution seems to be more important. Nuclide concentrations decrease with increasing distance from Sellafield; rates of decrease being in the order Zr + Nb > Ru > Cs. This can be related to the levels of the nuclides discharged, their sorption characteristics and their half lives. The pattern of seabed activity seems to have been fairly stable over the period 1978 - 1985, but there is evidence of a small northward shift. Concentrations of 137Cs and 106Ru in 1985 were considerably lower than in 1978 or 1982. This is explicable in terms of the fall in discharge levels allied, in the case of Ru, to its short half life and, for Cs, the desorption observed in laboratory experiments. Nuclide ratios in sediment samples yield apparent transit times for the transport of nuclides in the survey area of 1·7 - 3·7 years. These times are generally greater than those obtained from sediments in the more distant Solway Firth and Ravenglass Estuary. It is suggested that they reflect fairly intense bioturbation causing mixing of relatively recent effluent with that from earlier discharges. This is supported by structures observed in X-radiographs of box cores, an abundant burrowing benthos and by interpretations of nuclide profiles and radiocarbon dating of sediment cores by other workers.

    1996-01-01

    An audit was carried out of the solid low level and intermediate level radioactive waste at the Sellafield and Drigg sites of British Nuclear Fuels plc (BNFL) to establish the state of waste management. The audit was undertaken by a joint team of inspectors from the HSE's Nuclear Installations Inspectorate and HM Inspectorate of Pollution in line with their respective responsibilities for regulation of the storage and disposal of radioactive waste. The report records each solid waste facility and the conditions of storage observed by the team. The report reflects the views of the audit team. It should not be read as the definitive HMIP or NII judgement of the site's performance on waste matters. This continues to be based upon day to day interaction between allocated site inspectors and site managers. However, the recommendations of the team have been endorsed by HMIP and NII and accepted by BNFL. The report is published in two volumes. Volume 1 describes the aims and extent of the audit, the method of working and the findings and recommendations made. The reports on individual buildings are presented in Volume 2. These describe the waste management arrangements observed by members of the audit team. Where shortcomings are identified these have been brought to the attention of BNFL, and to the nominated site inspectors of HMIP and NII, in order that appropriate action may be considered to rectify the position. Where observations have lead to specific recommendations, these are indicated in Volume 2 at the point of arising. The recommendations are presented in full in Volume 1. Volume 1 also includes the overall conclusions of the audit and the recommendations which have been made as a result of the observations described in Volume 2. (UK)

    1987-01-01

    Field investigations into the transfer of 137 Cs from pasture to sheep tissues have been made at two contrasting sites in west Cumbria, close to the nuclear fuel reprocessing plant at Sellafield. These were a saltmarsh bordering on the Esk estuary in 1982 and inland pastures close to the perimeter of the works in 1984. 137 Cs concentrations of sampled vegetation from the saltmarsh were generally two orders of magnitude greater than from the inland pasture due to its inundation with 137 Cs associated with silt. The relatively high 137 Cs content of soil/silt compared to that of vegetation at each site meant that soil contamination of vegetation sometimes accounted for a substantial proportion of its 137 Cs activity (up to 99% on the saltmarsh and 67% on the inland pastures). Considerable seasonal changes occurred in the extent of 137 Cs contamination on the inland pastures, with late winter and early spring levels being up to 20-fold higher than those of the summer. 137 Cs concentrations in tissues of lambs from the saltmarsh were consistently higher than for ewes; this was not true for sheep from the inland pastures. 137 Cs concentrations in kidney were found to be higher than in all other tissues, both in the study flocks and in one of the controls. Transfer coefficients (calculated by dividing the 137 Cs concentration of fresh tissue by the daily intake of 137 Cs) were significantly (P 137 Cs activity due to soil/silt contamination was removed from the estimates of daily intake leaving 137 Cs associated with the vegetation only to contribute to the transfer coefficients. Further studies are required to determine the availability of 137 Cs associated with soil/silt particles which are ingested by animals. (author)

  11. Ventilation design for containment and the effects on energy consumption at Sellafield

    International Nuclear Information System (INIS)

    Doig, R.; Scattergood, B.; Standring, T.

    1997-01-01

    Nuclear reprocessing plants are designed to contain some radioactive process, minimise the risk of loss of containment and to limit the discharge of material to the environment. The physical containment systems, provided by the building and process vessels, are generally insufficient measures on their own to safeguard against release of contamination. This passive' containment must be enhanced by an active' containment - the ventilation system. The ventilation system is designed to provide a depression gradient so that air flows from areas of lesser to greater contamination potential and thereby limit the possibility of migration of contamination. The ventilation design is dominated by the extract system, which is used to create the differential pressures required to obtain the desired depression gradient. The resultant, contaminated, exhaust air requires considerable clean-up equipment to treat it prior to discharge to atmosphere. Within the nuclear industry, safety has always been paramount and will continue to be so, however, in recent years additional requirements have grown in importance and one of these has been energy conservation. At the same time, pressure has increased from the industry regulators to reduce discharges to atmosphere. A case study has been carried out on an existing plant at Sellafield, Cumbria, to review energy consumption and potential savings. This review was based on operational experience and evolution in containment and ventilation design which have occurred in intervening years. Completed in 1984, at a capital cost in excess of Pound 300m, the Fuel Handling Plant (FHP) at Sellafield, has one of the largest heating and ventilation systems in Europe. Costing approximately Pound 11m, the various ventilation systems comprise some 27 individual sub-systems using 58 fans, some 1,000 dampers and approximately 10 miles of ductwork spread over three buildings (integrated to form one whole).

  12. Development of a Systematic Approach to Post-Operation Clean Out at Sellafield

    International Nuclear Information System (INIS)

    2016-01-01

    Post Operational Clean Out (POCO) relates to the activities undertaken directly after commercial operations cease to remove residual activity and facilitate decommissioning of a nuclear facility. Historically the transition of Sellafield facilities has proved sub-optimal resulting in loss of critical plant knowledge, additional cost and protracted delivery timelines. The move from reprocessing in Magnox and Thorp to POCO is a significant transition facing the site, with a large number of diverse facilities scheduled to cease operations over the next 15 years. In order to ensure that the facilities are dealt with in a consistent manner, that supports both Site and Nuclear Decommissioning Authority (NDA) strategies, the POCO programme has been established across the Sellafield Operations Division. Primary aims of the POCO programme are: - Risk and Hazard Reduction; - Enabling redeployment of resource and capability; - Life-cycle cost reduction; - Enhanced Reputation. Transition preparations will cover process, organisation, technology and information. Knowledge is a key output of POCO: the creation of records of the plant configuration and status to enable and support the safe and effective eventual decommissioning of the plant. The consistent approach that has been developed will: - Ensure the smooth transition from operations into POCO, and then into surveillance and maintenance. - Maximise the potential of facilities to support other site activities prior to POCO. - Optimise the facility schedules within the overall POCO programme, to ensure timely decoupling. - Define and manage the resource demands and capabilities prior to and during POCO. - Provide a baseline configuration for each facility at the end of the POCO phase. - Encourage and enable knowledge management to ensure that subsequent decommissioning activities are informed and supported. - Look for opportunities to progress housekeeping and co-processing activities so as to reduce inventory and make best

  13. How an integrated change programme has accelerated the reduction in high hazard nuclear facilities at Sellafield

    2013-01-01

    For over five decades the Sellafield Site has been central to the UK's nuclear programme. Now operated by Sellafield Ltd, under the management of Parent Body Organisation Nuclear Management Partners (NMP), a consortium of URS Washington Division, AMEC and AREVA is focussed on the decommissioning of historical facilities. When Decommissioning commenced in the late 1980's the site focus at that time was on commercial reprocessing and waste management. Now through the implementation of a company change programme, emphasis has shifted towards accelerated risk and hazard reduction of degraded legacy plants with nuclear inventory whilst ensuring value for money for the customer, the Nuclear Decommissioning Authority. This paper will describe the management success by the Site owners in delivering a successful change programme. The paper will explain how the site has transitioned to the INPO Standard Nuclear Performance Model (SNPM) and how through the use of a change maturity matrix has contributed to the accelerated reduction in high risk high hazard nuclear facilities. The paper will explain in detail how the Decommissioning Programme Office has facilitated and coordinated the Governance and assured delivery of the change plan and how successful application of visual management has aided the communication of its progress. Finally, the paper will discuss how the Delivery Schedules have proved critical for presenting the change plan to Key Stakeholders, Government Owners and Powerful Regulators. Overall, this paper provides an insight into how a massive change programme is being managed within one of the world's highest regulated industries. (authors)

  14. A comparison between the risks of childhood leukaemia from parental exposure to radiation in the Sellafield workforce and those displayed among the Japanese bomb survivors

    Little, M.P.

    1990-01-01

    The cases of childhood leukaemia found near the Sellafield plant and those observed in the offspring of the Japanese bomb survivors are analysed using a relative risk model. The leukaemia relative risk coefficients for total paternal (whole-body) pre-conception exposure for the Sellafield children are found to be about 50 to 80 times higher than the (gonadal) coefficients applying to the offspring of the bomb survivors. This difference is statistically significant, and in particular the risk coefficients for the Sellafield cohort are significantly positive, unlike those for the Japanese. If the assumption is made that the excess relative risk estimated from the Sellafield data lasts for the whole of the life of the offspring, the apparent population leukaemia risk to the first-generation offspring (for an England and Wales population) would be between 4% Sv -1 and 5% Sv -1 .

    Extensive monitoring of conventional agricultural produce in the vicinity of the BNFL Sellafield plant is undertaken, by both the operator and the Ministry of Agriculture, Fisheries and Food, to determine levels of radioactivity and douses arising to the consumer Monitoring is also undertaken, albeit less extensively, for market garden and domestic produce. By contrast, few data exist with respect to levels of radioactivity in 'wild foods' (e.g. hedgerow fruits, field mushrooms etc.) or associated consumption habits. It has been postulated that such foodstuffs could contribute an appreciable radiation exposure dose to groups of high level consumers, potentially including members of the existing identified critical group for local agricultural produce. This paper assess the actual radiological significance of wild foods collected near Sellafield. (author)

    The nuclear energy industry produces radioactive waste at various stages of the fuel cycle. In the United Kingdom, spent fuel is reprocessed at the Sellafield facility in Cumbria on the North West coast of England. Waste generated at the site comprises a wide range of radionuclides including radiocarbon ((14)C) which is disposed of in various forms including highly soluble inorganic carbon within the low level liquid radioactive effluent, via pipelines into the Irish Sea. This (14)C is rapidly incorporated into the dissolved inorganic carbon (DIC) reservoir and marine calcifying organisms, e.g. molluscs, readily utilise DIC for shell formation. This study investigated a number of sites located in Irish Sea and West of Scotland intertidal zones. Results indicate (14)C enrichment above ambient background levels in shell material at least as far as Port Appin, 265 km north of Sellafield. Of the commonly found species (blue mussel (Mytilus edulis), common cockle (Cerastoderma edule) and common periwinkle (Littorina littorea)), mussels were found to be the most highly enriched in (14)C due to the surface environment they inhabit and their feeding behaviour. Whole mussel shell activities appear to have been decreasing in response to reduced discharge activities since the early 2000s but in contrast, there is evidence of continuing enrichment of the carbonate sediment component due to in-situ shell erosion, as well as indications of particle transport of fine (14)C-enriched material close to Sellafield.

    The objective was to determine whether population mixing produced by large, non-nuclear construction projects in rural areas is associated with an increase in childhood leukaemia and non-Hodgkin's lymphoma. A study was undertaken of the incidence of leukaemia and non-Hodgkin's lymphoma among children living near large construction projects in Britain since 1945, situated more than 20 km from a population centre, involving a workforce of more than 1000, and built over three or more calendar years. A 37% excess of leukaemia and non-Hodgkin's lymphoma at 0-14 years of age was recorded during construction and the following calendar year. The excesses were greater at times when construction workers and operating staff overlapped (72%), particularly in areas of relatively high social class. For several sites the excesses were similar to or greater than that near the nuclear site of Sellafield (67%), which is distinctive in its large workforce with many construction workers. Seascale, near Sellafield, with a ninefold increase had an unusually high proportion of residents in social class I. The findings support the infection hypothesis and reinforce the view that the excess of childhood leukaemia and non-Hodgkin's lymphoma near Sellafield has a similar explanation. (author)

    Proof of Evidence is given by an expert witness on behalf of Greenpeace Ltd as part of their submission to a Planning Inquiry in 1995 hearing the application of UK Nirex Ltd for permission to construct an underground Rock Characterisation Facility (RCF) at a site near Sellafield. The RCF is part of an investigation by Nirex into a suitable site for the disposal of radioactive waste. An examination of the groundwater flow models used by Nirex and the procedure for their validation have led to the following conclusions: no evidence has been presented by Nirex to show that the construction of the RCF will improve the confidence they claim to have in the site; the prospects are slim for validating the models of present groundwater flow so that they satisfy the criteria to meet the risk target; it is extremely unlikely that results from the RCF will increase confidence in a safety assessment of this site; all the evidence available to date suggests that the risk assessment is not, and will not become, robust to variations in flux through the repository.

    Source terms and corresponding radionuclide activity concentrations in biota for {sup 134}Cs, {sup 137}Cs, {sup 238}Pu, {sup 239+240}Pu and {sup 241}Am have been assessed for three semi-natural ecosystems in the vicinity of BNFL Sellafield, Cumbria, UK. Estimates of absorbed doses (mGy.d{sup -1}) have been calculated. Doses to key indicator species, Oniscus asellus (detritivorous invertebrate), Carabus violaceous (predatory invertebrate) and Apodemus sylvaticus (granivorous wood mouse) are discussed with reference to the 1 mGy.d{sup -1} level, below which it is postulated that no observable effects on populations in a terrestrial ecosystem occur. Implications for the 'critical group' and 'reference model' approaches for a framework of radiological environmental protection are discussed. The need to assess the most highly exposed species is advanced. New research focused on the application of biomarker techniques as a mechanism for determining the interactions and effects of environmental contaminants on ecosystem structure and functioning is presented.

  20. A new approach to the criticality safety assessment of PCM at BNFL Sellafield

    Plutonium Contaminated Material (PCM) arises as a solid waste on the Sellafield Site and is packaged into 200 litre drums which are placed into interim surface storage arrays. These wastes may also contain 235 U. The traditional approach to criticality safety has been based on ''worst-case'' reactivity modelling. This has recently led to a number of difficulties by implying that the 230 g (Pu + 235 U) drum limit is very important for criticality safety and the assay instruments used to demonstrate compliance with the limit need a high level of safety reliability. Also, the reliability and accuracy of the assay results of historical or legacy PCM became an issue. The new focus on substantiation of safety related equipment in BNFL has highlighted reliability shortfalls for the assay instruments. To overcome these shortfalls, additional operational practices on the PCM handling regimes were introduced to give increased confidence in the fissile assay results. These practices significantly delayed processing PCM waste stocks and resulted in significant additional operator dose uptake. Thus there were strong reasons to improve the existing approach. This paper describes a new approach to the criticality modelling of PCM. (author)

  1. The Thermal Oxide Reprocessing Plant at Sellafield - Lessons Learned from 10 Years of Hot Operations and their Applicability to the DOE Environmental Management Program

    2006-01-01

    The Thermal Oxide Reprocessing Plant (Thorp) at Sellafield in northwest England is a $4 billion integrated plant that takes irradiated fuel from worldwide Light Water Reactors and UK Gas-Cooled Reactors and separates the uranium and plutonium from the fission products so that the latter can be vitrified and safely stored. The uranium and plutonium are further separated so that the uranium can be recycled as new reactor fuel, either by itself or in combination with the plutonium as Mixed Oxide (MOX) fuel. Thorp concentrates in excess of 99% of the radioactivity in the irradiated fuel into the vitrified waste product and produces a 40-fold reduction in high active waste volume to be stored, in comparison with direct disposal of the fuel. Thorp incorporates a range of design and operational principles developed over the 50 year history of the Sellafield site. These include the extensive use of no-moving part, no-maintenance equipment in contact with radioactive material, located in shielded 'dark cells' where entry is not expected through the life of the plant. These cells are nevertheless provided with comprehensive secondary containment, instruments, wash-down and recovery systems, and access for cameras and potentially also for remote repair equipment. These arrangements were found to be required during an unusual incident identified in early 2005 when approximately 83 m 3 of highly active liquid escaped from primary tank containment into the secondary containment formed by the dark cell and its stainless steel liner. Although a serious incident, the secondary containment and the in-cell design provisions worked exactly as designed and the liquid was recovered by mid 2005 with no releases to the environment and no member of the workforce or public affected. The ability to access and clean dark cells means that repairs are possible and the large capital asset is thus protected. The enquiry that followed this incident identified issues with carry-through of late

  2. The identification of an homogenous critical group using statistical extreme-value theory: application to laverbread consumers and the Windscale effluent discharges

    The International Commission of Radiological Protection states that a critical group should be representative of those individuals in the population expected to receive the highest dose. The appropriate dose limit should then be applied to the mean dose of this group. The edible seaweed Porphyra (laverbread) has been identified as the link in the critical exposure pathway limiting discharges of controlled low-level radioactive liquid waste from Windscale. The frequency distributions of the largest values of samples of 10, 20, 30, 40 and 50 male and female, child and adult consumers of laverbread are determined from the parent distributions by Monte Carlo sampling methods. From these results the extreme-value distribution of adult males of samples of 30 is taken to be a good estimate of the critical group, from which the median consumption rate of laverbread consumed per day is 55 g. The annual collective organ dose delivered to the lower large intestine of the total laverbread consumer group is estimated to be 266 man-rem. (author)

    In January 1994, British Nuclear Fuels plc (BNFL) were granted revised authorizations for disposal of radioactive wastes from their Sellafield site in Cumbria, UK, including the discharge of liquid effluent to the Irish Sea. The revisions took account of a continuing Government commitment to review authorizations regularly, as well as of new Sellafield plants and changes to existing operations. The new plants of prime importance were the Thermal Oxide Reprocessing Plant (THORP) for the reprocessing of oxide fuels, and the Enhanced Actinide Removal Plant (EARP) for improved treatment mainly of waste streams from the older, Magnox, plant. Revision of the liquid authorization is described in reference 1. Many of the radionuclide discharge limits reduced significantly, notably for Cs-137, Ru-106 and the actinides, to reflect operation of EARP. Increases in limits, of relatively low radiological significance, were granted for tritium and I-129 which would be produced by operation of THORP. An increase for C-14 covered diversion to sea of Magnox gaseous scrubber liquors, so as to reduce the overall radiological impact of these waste streams. Increases for Sr-90 and especially Tc-99 were to allow discharge, after phased processing through EARP, of liquors which have been stored on site for an optimised period to allow radioactive decay. Tc-99 is not treated by EARP, and Sr-90 is treated less effectively than the actinides or radiocaesium. (author)

    Graphical abstract: Storage of 200 L drums of PCM waste at the Sellafield site, UK. Abstract: Four waste simulants, representative of Plutonium Contaminated Materials (PCMs) at the Sellafield site, were vitrified through additions of Ground Granulated Blast-furnace Slag (GGBS). Ce (as a Pu surrogate) was effectively partitioned into the slag product, enriched in an amorphous CaO–Fe{sub 2}O{sub 3}–Al{sub 2}O{sub 3}–SiO{sub 2} phase when other crystalline phases were also present. Ce L{sub 3} edge XANES data demonstrated Ce to be present as trivalent species in the slag fraction, irrespective of the waste type. Estimated volume reductions of ca. 80–95% were demonstrated, against a baseline of uncompacted 200 L PCM waste drums. The dissolution behaviour of PCM slag wasteforms was investigated at 50 °C in saturated Ca(OH){sub 2} solution under N{sub 2} atmosphere, to simulate the hyperalkaline anoxic environment of a cementitious UK Geological Disposal Facility for Intermediate Level Waste (ILW). These experiments demonstrated the performance of the slag wasteforms to be comparable to that of other vitrified ILW materials considered potentially suitable for geological disposal.

    Detailed comments are made on behalf of Greenpeace Ltd in a Supplementary Proof of Evidence presented to a Planning Inquiry in 1995 in support of their objections to an application by UK Nirex Ltd for permission to construct an underground Rock Characterisation Facility (RCF) at a site near Sellafield. The RCF is part of an investigation by Nirex into a suitable site for the disposal of radioactive waste. The principal points of disagreement with Nirex concern: the promise of the site; the oxidation state of the natural groundwater and uranium solubility; effects of possible future earthquakes; the interpretation of flow potential; the application of fluid flow modelling and the parameters used in it.

    A survey of people's consumption rates in 1981 and 1982, of fish and shellfish caught near the British Nuclear Fuels plc (BNFL) Sellafield site is described. Particular emphasis has been given to mollusc eaters and consumption rates of children because of the potentially higher radiation doses they may receive. Appropriate critical groups have been selected for dose assessment purposes using principles recommended by the International Commission on Radiological Protection (ICRP). Methods for consideration of children in critical groups are suggested and a comparison of these methods using the present data shows similar results. Combination of seafood consumption pathways is also considered, and it is shown that a simple additive approach is not excessively conservative. (author)

    The Legacy Ponds and Silos (LP and S) facilities are part of the UK nuclear legacy located at the Sellafield Site, Cumbria. There are four individual facilities containing nuclear wastes that have accumulated over a period of approximately 50 years. Waste retrieval and conditioning, in preparation for decommissioning, is currently being carried out by the site operator. LP and S have recently proposed a re-engagement with stakeholders following the initial engagement in December 2005. This paper reviews this earlier engagement in terms of the nature of dialogue that was carried out when compared against definitions of deliberation provided in the literature. The aim of this paper is to provide those planning future engagement with a better understanding of how the nature of dialogue can vary and uses participation and deliberation as indicators of effective engagement. A concern of those working towards a programme of effective stakeholder participation in 2005 was how to ensure genuine dialogue and stakeholder representation in such a strictly controlled and regulated environment with a technical complexity that challenges technical specialist and lay person alike. LP and S recognised that effective dialogue with stakeholders on the available technical options and their associated societal impacts would form a significant part of this process if options were to prove resilient. However, the challenge presented to LP and S was how to engage stakeholders on a variety of projects, whilst ensuring the output could be used by the projects as part of their technical decision making. Initial contact was made with stakeholders in December 2005, as part of a 'Baseline' Best Practicable Environmental Option (BPEO) study. A BPEO study leads to decisions on waste management based on an integrated assessment of alternative options, on the basis of factors such as the occupational and environmental risks, the environmental impacts, costs and social implications of the options

    Liquid wastes containing low levels of radioactivity have been discharged to the Irish Sea from the nuclear fuel reprocessing site at Sellafield since operations began in the early 1950s, and monitoring of radioactivity in foodstuffs has been undertaken over many years. Based on the best available monitoring data, supplemented by modelled values where necessary, doses to local critical groups have been reassessed using the most recent dosimetry. Contemporary habits data have been used where available, again supplemented by assumed habits where necessary. During the 1950s and 1960s the highest doses were received by individuals consuming Cumbrian Porphyra as laverbread, and peak doses around 0.8 to 1.0 mSv year{sup -1} have been estimated. During the 1970s and 1980s the critical exposure group switched to consumers of local fish and shellfish, with peak doses possibly reaching 2.5 to 3.0 mSv year{sup -1}. Latterly, doses to all marine-related groups have declined to less than 150 to 200 {mu}Sv year{sup -1}. At all times, doses have been within the appropriate limits set for members of the public.

    The emission of krypton-85 ( 85 Kr) from nuclear fuel reprocessing operations provide a classical passive tracer for the study of atmospheric dispersion. This is because of the persistence of this radioisotope in the atmosphere, due to its long radioactive halflife and inert chemistry; and the low background levels that result due to the limited number of anthropogenic sources globally. The BNFL Sellafield site in Cumbria (UK) is one of the most significant point sources of 85 Kr in the northern hemisphere, with 85 Kr being discharged from two stacks on the site, MAGNOX and THORP. Field experiments have been conducted since October 1996 using a cryogenic distillation technique (Janssens et al., 1986) to quantify the ground level concentration of 85 Kr. This paper reports on the construction of a model validation database to allow evaluation of regulatory atmospheric dispersion models using the measured 85 Kr concentrations as a tracer. The results of the database for local and regional scale dispersion are presented. (orig.)

  14. Investigation of stillbirth risk among the offspring of male radiation workers at the Sellafield nuclear installation, west Cumbria

    2000-04-01

    Ionising radiation is a known mutagen, much of the evidence coming from studies on animals, and from studies of occupationally exposed workforces and those exposed after the atomic bombings of Hiroshima and Nagasaki. However, few studies have examined transgenerational effects of paternal exposure in humans. The workforce at the Sellafield nuclear reprocessing plant in west Cumbria, is the most highly exposed such workforce in Western Europe and North America. This epidemiological investigation set out to determine whether there was evidence of an association between stillbirth risk and paternal preconceptional exposure to external ionising radiation or internal radionuclides. Logistic regression was used to analyse the relationship between stillbirth risk and paternal preconceptional irradiation (ppi). Further modelling of the risk of stillbirth in relation to ppi was carried out using overdispersion and variance components models. The form of doseresponse was investigated using both threshold and broken-stick models, in addition to varying the power function of the dose term. To assess the effect of errors in the dose estimates for the immediate preconceptional period resulting from the derivation of doses for short intervals pro rata from annual dose summaries, a nested case-control study was also carried out. This used more precise estimates of external doses estimated directly from monthly film badges and internal doses from special dose assessments, which were very time consuming to collate and would have taken several years to compile for the entire workforce. A significant positive association was found between the risk of a child being stillborn and total external ppi (adjusted odds ratio per 100 mSv, 1.25 95% CI 1.04-1.46, p=0.019). The risk was higher for stillbirths with congenital anomaly and was highest for the nine stillbirths with neural tube defects, eight of which were anencephalic, the other spina bifida. Although, the possibility of an

    We present preliminary results of the analysis of the Sellafield cohort of workers. The mortality and morbidity experience of these 28,973 employees to the end of 1998 is reported. These workers have accumulated 669,303 person-years of experience, with a mean follow-up time of 23.1 years. The low level of untraced workers, 0.27%, is indicative of the quality of the data set. The cohort has 21,537 radiation workers, 10,623 of which are classified as plutonium workers. The radiation workers have received 1,715 person-sieverts of external whole body radiation dose, 76% of which has been received by the plutonium workers. Of the plutonium workers that had been monitored, 77% (8,173) had provided sufficient urinalysis samples (i.e.{>=} 5), for the calculation of the organ-specific plutonium doses using ICRP 60/66 dose models. Both the plutonium (SMR=93, p<0.001; 1,787 deaths) and other radiation workers (SMR=91, p<<0.001; 1,850 deaths) show the healthy worker effect, though this was not apparent amongst the non-radiation workers (SMR=102, p=0.37; 1,551 deaths,). Though there was no difference in the 'all causes' mortality experience when the plutonium workers were compared with the other radiation workers, the 'all causes' mortality experience for all radiation workers was significantly lower than that for the non-radiation workers (RR=0.88, p<0.001)

    British Nuclear Fuels completed construction of its Thermal Oxide Reprocessing Plant (THORP) at Sellafield in 1992, at a cost of 1,850M. After Government and Regulatory approval, active commissioning was initiated on 17 January 1994. From the outset, the need to protect the workforce, the public and the environment in general from the plant`s discharges was clearly recognised. The design intent was to limit radiation exposure of members of the general public to As Low as Reasonably Practicable. Furthermore no member of the most highly exposed group should receive an annual dose exceeding 50 microsieverts from either the aerial or marine discharge routes. This paper describes how the design intent has been met with respect to aerial discharges. It outlines the development programme which was undertaken to address the more demanding aspects of the performance specification. This ranged from small-scale experiments with irradiated fuel to inactive pilot plant trials and full-scale plant measurements. The resulting information was then used, with the aid of mathematical models, in the design of an off-gas treatment system which could achieve the overall goal. The principal species requiring treatment in the THORP off-gas system are iodine-129, carbon-14, nitrogen oxides (NOx), fuel dust particles and aerosols containing plutonium or mixed fission products. The paper describes the combination of abatement equipment used in different parts of the plant, including counter-current absorption columns, electrostatic precipitators, dehumidifiers and High Efficiency Particulate Air filters. Because a number of separate off-gas streams are combined before discharge, special depression control systems were developed which have already proved successful during plant commissioning. BNFL is confident that the detailed attention given to the development and design phases of the THORP off-gas system will ensure good performance when the plant moves into fully radioactive operation.

    A comparison is made of the relative risks associated with paternal pre-conception irradiation of stillbirth and untoward pregnancy outcome (stillbirths, congenital malformations, neonatal deaths) in the offspring of the Japanese atomic bomb survivors and of stillbirth in the offspring of Sellafield workers. It is concluded that the pre-conception exposure risks of stillbirth in the offspring of Sellafield workers are statistically incompatible with the Japanese data at the 5% level. Other human and experimental data relating to the induction of congenital abnormalities are briefly reviewed. (author)

    1991-01-01

    The purpose of this communication is to summarize briefly selected studies relevant to the difference between the apparent pre-conception radiation-associated leukemia risks in the offspring born in the area near the Sellafield plant and to the atomic bomb survivors. Although no doubt exists about the hypothesis that radiation damages the genetic material in reproductive cells, it is important to recognize how small the effect in the first generation would be based on the various genetic endpoints. Generally only a small fraction of leukemia cases are inherited -- the proportion among all spontaneous cases does not exceed 10 %. Because there is still uncertainty and controversy about the genetic effects of radiation, the possible complex confounding factors are also briefly mentioned. It is clear that the studies of the atomic bomb survivors are pertinent to the possible genetic effect due to radiation-induced mutations in the spermatogonia and oocytes while the observations in Sellafield are, as suggested by Gardner et al. pertinent to the in post-meiotic stages of spermatogenesis. No significant effect of atomic bomb radiation can be shown on the risk of leukemia as well as other genetic effect endpoints, such as the frequency of mutations associated with specific proteins, cytogenetic abnormalities, survival, and so on.

    A programme of monitoring carried out since 2006 has found radioactive objects on beaches near the Sellafield nuclear reprocessing site in West Cumbria. These objects comprised particles with sizes smaller than or similar to grains of sand (less than 2 mm) and contaminated pebbles and stones. Public Health England has undertaken an assessment of the health risks to people using the beaches along the Cumbrian coast from these contaminated objects. The assessment has addressed two key aspects. Firstly, estimates have been made of the likelihood that people using the beaches for various activities could come into contact with a radioactive object. Secondly, for the unlikely event that an individual does come into contact with such an object, the resulting radiation doses and associated health risks have been assessed. The ingestion of an 'alpha-rich' particle (a particle for which the content of the alpha-emitting radionuclide americium-241 exceeds the content of caesium-137) has the greatest potential to give rise to significant health risks. The intestinal absorption of a range of particles recovered from West Cumbrian beaches was quantified by means of in vivo uptake studies using laboratory rats, and the results were used to predict doses that would result from the ingestion of a single particle. The conclusion of the assessment, based on the currently available information, is that the overall health risks to beach users are very low and significantly lower than other risks that people accept when using the beaches. The highest calculated lifetime risks of radiation-induced fatal cancer are of the order of one hundred thousand times smaller than the level of risk that the UK Health and Safety Executive considers to be the upper limit for an acceptable level of risk (1 in a million) for members of the public and workers. The exposure route with the greatest potential for deterministic effects, such as localised skin ulceration, is direct irradiation of

  20. The effect of extent of site investigation on the estimation of radiological performance and its relevance to the proposed Rock Characterisation Facility at Sellafield

    Proof of Evidence is given by an expert witness on behalf of Greenpeace Ltd as part of their submission to a Planning Inquiry in 1995 hearing the application of UK Nirex Ltd for permission to construct an underground Rock Characterisation Facility (RCF) at a site near Sellafield. The RCF is part of an investigation by Nirex into a suitable site for the disposal of radioactive waste. The evidence concerns the necessity of establishing an adequate hydrogeological model of the site in advance of the construction of the RCF in order to estimate its radiological performance. This detailed examination of Nirex's approach concludes that it is not apparent that a method for demonstrating the adequacy of the conceptual hydrogeological model has been clearly and openly stated so that it may be agreed in advance of construction with an appropriate authority.

    1997-05-01

    This report covers the waveform processing and analysis of digital data from the DSI Dipole Shear Sonic Imager logged on Sellafield Borehole 16 as Run 2B on 11th February 1997. The aims of this data processing were the determination of compressional slowness, compressional to shear and Poisson's ratios for mechanical properties computations and the Stoneley slowness for the identification of fractures. The data quality was generally good, though data from the Upper Dipole mode were used where P and S monopole shear data were poor, between 512 and 352m. The resultant determination of compressional and shear slowness is good throughout the logged interval. All events identified as possible fractures from the Stoneley processing appear on the Fracture Log. (author)

    2000-01-01

    British Nuclear Fuels plc (BNFL) are authorised to discharge low level liquid radioactive wastes from the nuclear reprocessing plant at Sellafield into the Irish Sea. The current authorisation took effect in January 1994 and allowed operation of the Thermal Oxide Reprocessing Plant (THORP) which reprocesses oxide fuels from the UK and abroad, and the Enhanced Actinide Removal Plant (EARP) which treats current and historic liquid wastes, particularly to remove transuranic radionuclides. The authorisation included reduced discharge limits for radionuclides of greatest radiological significance, such as 106 Ru, 137 Cs and the transuranics, and increased limits for some nuclides of low radiological significance, including 3 H, 14 C, 99 Tc and 129 I. Changes in operations on site have been reflected in the amounts of liquid radioactive waste discharged, and this paper describes and explains the trends in discharges for 14 C, 60 Co, 90 Sr, 99 Tc, 106 Ru, 137 Cs, 239 Pu+ 240 Pu and 241 Am over the period 1990-98. CEFAS undertakes a comprehensive programme of aquatic environmental monitoring around Sellafield on behalf of the Ministry of Agriculture, Fisheries and Food, and the paper describes the trends in monitoring results, relating them to changes in discharge patterns and environmental influences. Increased discharges of 99 Tc resulting from treatment of stored historic wastes in EARP have been of particular environmental interest; more detailed data are therefore included. The effects in terms of radiological significance to the potentially critical group of fish and shellfish consumers are also presented, showing the changes in contributions due to different radionuclides. Doses have ranged from 0.11 - 0.16 mSv y -1 and this is partly due to changed radionuclide concentrations in seafoods, but also changing patterns in the amounts of seafood eaten by the group. Predictions for future trends of environmental impact are described. (author)

  3. The risks of leukaemia and non-cancer mortality in the offspring of the Japanese bomb survivors and a comparison of leukaemia risks with those in the offspring of the Sellafield workforce

    The incidence of leukaemia and mortality from various causes other than cancer observed in offspring of the Japanese bomb survivors are analysed using linear and exponential forms of a relative risk model. Relative risk coefficients for leukaemia as a function of total pre-conception dose in the offspring of the Japanese and those for children of the Sellafield workforce are compared, and statistically significant differences are found. The statistical significance of these differences is no less marked if attention is restricted to those born before the end of 1950 in the Japanese cohort; therefore it is unlikely that the differences between the preconception irradiation leukamia risks in the Japanese and Sellafield datasets are a result of different distributions of parental ages at exposure in the two groups, or of different lengths of time between exposures of spermatogonia and conception.

    The development and maintenance of the broad range of the highly technical skills required for safe and successful management of nuclear sites is of vital importance during routine operations, decommissioning and waste treatment activities.. In order to maintain a core team of technical experts, across all of the disciplines required for these tasks, the approach which has been taken by the Sellafield Ltd has been the formation of twenty five Centres of Expertise (CoE), each covering key aspects of the technical skills required for nuclear site operations. Links with the Specialist University Departments: The CoE leads are also responsible for establishing formal links with university departments with specialist skills and facilities relevant to their CoE areas. The objective of these links is to allow these very specialist capabilities within the university sector to be more effectively utilized by the nuclear industry, which benefits both sectors. In addition to the utilization of specialist skills, the university links are providing an important introduction to the nuclear industry for students and researchers. This is designed to develop the pipeline of potential staff, who will be required in the future by both the academic and industrial sectors. (authors)

  7. The complex challenge of repairing the gantry steelwork on the first generation magnox storage pond at Sellafield: Legacy Waste Storage, First Generation Magnox Storage Pond - 59133

    Richardson, Ian E.

    2012-01-01

    This paper puts into context the challenges that were faced when repairing the Gantry Steelwork of the First Generation Magnox Storage Pond (FGMSP). The First Generation Magnox Fuel Storage Pond (FGMSP) provided fuel storage and de-canning capability from the early 1960's until 1986. A significant programme of work has been underway since the completion of operational activities to support the programmes strategic intent of retrieving and storing all legacy wastes, and remediating the structure of the plant to support decommissioning activities. A key enabler to the retrievals programme is the Pond Skip Handler Machine (SHM), removed from service in 2002 following the discovery of significant signs of corrosion and distress, an inevitable consequence of being located in a coastal, salt laden environment. The SHM provides sole capability to access and retrieve the inventory of over 1000 fuel skips. It is also fundamental to future operations and the deployment of de-sludging equipment to recover significant bulk sludge's from the pond floor. Failure of the SHM steelwork gantry at worst case could potentially result in the Skip Handler Machine being derailed. This has some potential to damage to the pond structure and at worst case may result in local radiological and environmental consequences. This paper will examine the challenges faced by the team as they successfully defined, planned and executed remedial work to a specific aspect of the civil structure, the SHM gantry rail system, using a purpose built refurbishment platform; the Gantry Refurbishment System. The paper will examine how an 'innovative' approach was adopted to resolve the related issues of: - Refurbishing an aged structure to meet extended future operational demands. - The application of pragmatic engineering solutions against current codes and standards including seismic performance; - Provision of safe access for the workforce to undertake the refurbishment work against significant radiological

    Decommissioning projects at the BNFL Sellafield site have been selected taking the following into account; the need to gain experience in preparation for the decommissioning of the Magnox reactors and for the post Magnox stage; the need to develop larger scale projects; the need to be cost effective and to foster long term safety. The balance between prompt or delayed decommissioning has to consider operator dose uptake and radioactive waste management. The ten year plan for decommissioning at Sellafield is described briefly. Currently decommissioning is of the fuel pond and decanning plant, the Windscale Pile Chimneys, the coprecipitation plant and the uranium recovery plant. (author)

    1995-01-01

    The principal objective of Nirex is to develop a single deep geological repository for the safe disposal of low- and intermediate-level radioactive waste. In safety assessment, use is made of a variety of conceptual models that form the basis for modelling of the pathways by which radionuclides might return to the environment. In this paper, the development of a conceptual model for groundwater flow and transport through fractured rock on the various scales of interest is discussed. The approach is illustrated by considering how some aspects of the conceptual model are developed in particular numerical models. These representations of the conceptual model use fracture network geometries based on realistic rock properties. (author). refs., figs., tabs

    1991-01-01

    Planning of the second stage of decommissioning of the two pile chimneys at Sellafield started while work was underway on the first stage, which involved removal of the sections above the filters. The second stage requires the removal of all radio-active parts and the dismantling of the filter and diffuser sections, and has to be completed by 1997. The planning involved studying the many possible options and their effects on both radiological and industrial safety. This decommissioning project employs a high proportion of civil engineering and construction techniques, which are then developed to eliminate the hazards from radioactive dusts, and to minimise the effect of radiation on operatives working on the project. Much of this equipment is modified forms of standard construction equipment and includes cutting equipment and remotely operated vehicles. The initial phases of the work involve: provision of a waste packaging and access building; provision of temporary ventilation systems to control the dust generated by the work, cutting of 3 m square access doorway through the 1.5 m thick reinforced concrete wall of the chimney; provision of Remotely Operated Vehicle (ROV) to act as a tool carrier for lining stripping work; removal of the thermal lining from the floor and lower walls of the chimney, and installation of precast concrete walls which separate the pile reactor core from the chimney flue.

Whereas actors seek to diminish the amount of articulation work needed in collaboration......We posit the concept of Mobility Work to describe efforts of moving about people and things as part of accomplishing tasks. Mobility work can be seen as a spatial parallel to the concept of articulation work proposed by the sociologist Anselm Strauss. Articulation work describes efforts...... by constructing Standard Operation Procedures (SOPs), actors minimise mobility work by constructing Standard Operation Configurations (SOCs).

    1990-01-01

    Recently British Nuclear Fuels (BNFL) at Sellafield (formerly Windscale) have had to improve its image and have mounted a publicity campaign to improve its public relations and promote nuclear power. However, a study of the childhood leukemia excess acknowledged to exist near Sellafield has been made. Its finding show that in each case of leukaemia or lymphatic cancer in under-25s in West Cumbria between 1950 and 1985 the fathers had received higher radiation exposure at the Sellafield plant than had the fathers in a matched control group. Other studies support the theory that genetic damage to the fathers have given rise to a predisposition to develop leukemia in their children. Higher radiation levels in the local environment could then be another step in the cancer-causing process. The Sellafield reprocessing plant has been responsible for high levels of radioactivity in the Irish Sea, Cumbrian coast and beyond. If the main purpose of Sellafield is simply to make money the long term hazards to human genetic and food chains make this an unacceptable enterprise. (UK)

    The author says ''barehand'' methods, where specially trained utility workers are called in conductive suits to equalize voltage over their bodies, to maintain high-voltage transmission lines are on the rise. Utilities are building lines at higher voltages and selling more power to other utilities, making it highly inconvenient to take the lines out of service. However, some unions view the barehand work with less than enthusiasm. Touching lines energized at hundreds of thousands of volts demands flawless equipment and rigid work procedures followed to the letter. Some local unions contend that adequate safety procedures and training, and appropriate penalties for workplace negligence, should be in place before utilities may do barehand work. The author discusses some of the methods of barehand work and the equipment used, i.e. steel-mesh lineman's suit, bucket truck's boom, helicopters, and robots

    The distribution of /sup 137/Cs from the Sellafield (Windscale) nuclear fuel reprocessing plant has been examined in detail in the surface intertidal sediments of the inner Solway Firth by means of a hovercraft-borne radiometric survey. With the exception of a belt of relatively active sands to the south of Silloth, caesium distribution is generally consistent with that of fine-grained sediment such that the highest concentrations occur in mud flat and salt marsh sediments which are most extensive in sheltered coastal embayments. /sup 137/Cs activities in July 1980 were typically 2 to 30 pCi g/sup -1/ but locally exceeded 50 pCi g/sup -1/. These levels are considerably lower than those recorded in locations, such as the outer Solway and Ravenglass estuary, which are closer to the Sellafield outfall.

    1988-01-01

    The author discusses three cases in relation to confidence in nuclear energy: the fire at Windscale, the leaks at Sellafield reprocessing plant; and the Transnuklear/Nukem scandal. The first involved a reactor used for purely military purposes and it has been shown that there has been no verifiable damage to public health as a result of radiation leaks following the fire. Concerning the Sellafield radiation leaks it is stated that the assertion that there is a link between them and an increasing occurrence of leukemia is false. On the other hand, the offences verified in the Transnuklear scandal (bribery and false declarations) are to be severely condemned, although the safety of the population and the environment was never at risk. The author concludes that these events do not alter the fact that the nuclear power plants in the western world have an excellent safety record

The purpose of this paper is to test this hypothesis by using the Danish Time Use Survey 2001, where diary information as well as survey...

  18. Working memory.

    Baddeley, A

    1992-01-31

    The term working memory refers to a brain system that provides temporary storage and manipulation of the information necessary for such complex cognitive tasks as language comprehension, learning, and reasoning. This definition has evolved from the concept of a unitary short-term memory system. Working memory has been found to require the simultaneous storage and processing of information. It can be divided into the following three subcomponents: (i) the central executive, which is assumed to be an attentional-controlling system, is important in skills such as chess playing and is particularly susceptible to the effects of Alzheimer's disease; and two slave systems, namely (ii) the visuospatial sketch pad, which manipulates visual images and (iii) the phonological loop, which stores and rehearses speech-based information and is necessary for the acquisition of both native and second-language vocabulary.

    Organized criminals also tried to illegally transfer nuclear material through Austria. Two important questions have to be answered after the material is sized by police authorities: What is the composition of the material and where does it come from? By application of a broad range of analytical techniques, which were developed or refined by our experts, it is possible to measure the exact amount and isotopic composition of uranium and plutonium in any kind of samples. The criminalistic application is only a byproduct of the large scale work on controlling the peaceful application of nuclear energy, which is done in contract with the IAEA in the context of the 'Network of Analytical Laboratories'

    1996-01-01

    BNFL's operations, which support a global nuclear fuel cycle business and serve many companies in Pacific Basin countries, have been the subject of refinement from 40 years of experience. Many of the Company's operating philosophies are consistent with the principles of sustainable development. The paper acknowledges the important role that the nuclear industry can play in satisfying energy demands within economies of diminishing natural resources and societies which are becoming increasingly concerned about their impact on the environment. It explains how reprocessing can meet many of the criteria of sustainable development through recycling and the optimization of resources. It describes how BNFL have reduced the impact of its operations on the environment through the treatment of discharges and the minimization and stabilization of wastes requiring disposal. The establishment of BNFL Engineering Ltd as an outlet to the world markets for BNFL's engineering expertise and technology is covered. The paper looks at the responsible approach that BNFL is taking to liabilities management ensuring that no surprises are left for future generations. BNFL's commitment to the present and future of nuclear electricity generation is illustrated in the extent to which it is committed to making it operations safer and more cost effective through investment in research and development. The paper describes BNFL's commitment to the development of its employees and to the development of the communities in which it operates. The paper considers how BNFL has met its many challenges and draws out examples of sustainable development in practice. (author)

  5. Retrieval of wastes from interim storage silos at Sellafield

    1998-01-01

    BNFL have several large stores of intermediate level waste (ILW). Some of the waste is stored dry, and some of the waste is stored under water. Retrieval of ILW from these stores is in progress and when empty, the stores will be decommissioned. This paper outlines some of the issues and lessons learnt when providing a safety case for such facilities, both for the current operational stage and for future operations and decommissioning. Examples are given of where issues have arisen (structural performance, inventory characteristics, hydrogen release, temperature monitoring, fire) and of how they have been, or are being, resolved. To address the issues involved where significant modifications are being made to a plant (e.g. decommissioning operations) a 'live safety case' approach has been adopted. This consists of an overview that refers out to the other safety cases or documents, providing a live summary of what comprises the safety case, listing any operating rules or safety mechanisms and providing details of the risk presented by current operations. This paper concludes that following this approach it has been possible to maintain a Safety Case that addresses current live safety issues appropriately at all stages of the project

    1984-02-01

    Contaminated material continues to be found on the beaches, estuaries and salt marshes. An initial apparent fall in the frequency of discovery of highly contaminated samples has not been sustained. In the last week of surveys reported here, a change was noted in the type of contaminated material found. Results averaged on the entire period from 19 November 1983 to 13 February 1984 suggest that about 2 items every kilometre might be found giving a reading in excess of 1 mR/L βγ and 1 item every few kilometres giving a reading in excess of 10 mR/h βγ, with actual contact dose rates possible of about a hundred times higher than apparent instrument readings. A member of the public could pick up an item contaminated in excess of the 10 mR/h βγ or 1000 cps criterion and hold it for sufficiently long to sustain an appreciable dose to the skin surface. These and laboratory studies of contaminated materials confirmed the Board's views that the only situations of concern are those of prolonged handling of debris and contamination of the skin, rather than intake by ingestion or inhalation.

  7. Windscale nuclear power development laboratories power ramp experience in the Winfrith SGHWR (UK)

    International Nuclear Information System (INIS)

    Garlick, A.; Sumerling, R.; Stuttard, A.; Bond, G.G.; Howl, D.A.; Fox, W.N.; Cordall, D.; Cornell, R.M.

    SGHWR fuel has sufficient power ramping capability to permit considerable latitude in fuel management schemes. However, beyond some limiting ramping conditions, there is risk of fuel defecting. Controlled ramp experiments were therefore carried out in the reactor in order to determine the defect mechanism and define the fuel operating limitations. Cladding cracks produced during these power ramps are considered to have been a consequence of fission product stress-corrosion attack. A critical stress level for cracking, based on laboratory stress corrosion tests, have been used successfully in conjunction with computer codes to calculate cladding stresses and strains in fuel rods. Initial analysis of the conditions under which a fuel element defected at 11.6 MWd/kgU suggests that the threshold stress for failure may be decreased compared with elements at lower burn-up (5-6 MWd/kgU)

    Experiments are described in which water has been brought into contact with various molten metals in a shock tube, thus simulating the fall of coolant into molten uranium dioxide in a postulated reactor accident. Impact velocities of the water on to the molten material were in the range 5 to 7 m/s. Shock-pulse pressures in the water column after impact and particle size distributions of the dispersed resolidified material that was recovered were measured. The proportion of dispersed material and the size of the shock pulse (by comparison with that expected from water hammer alone) have been used as criteria for the occurrence of a molten fuel/coolant interaction and such interactions of varying degrees of violence have been found for water/aluminium, water/bismuth, water/tin, over a range of temperatures from 350 0 C to 950 0 C, for water/boric oxide, but not for water/magnesium.

    Research purpose: The aim of the study was to investigate the relationships amongst psychological meaningfulness, work engagement and organisational commitment and to test for a possible mediation effect of work engagement on the relationship between psychological meaningfulness and organisational commitment. Motivation for the study: Managers have to rethink ways of improving productivity and performance at work, due to the diverse, and in some instances escalating, needs of employees (e.g. financial support to uphold their interest in and enjoyment of working. Research approach, design and method: A quantitative approach was employed to gather the data for the study, utilising a cross-sectional survey design. The sample (n = 415 consisted of working employees from various companies and positions in Gauteng, South Africa. Main findings: The results confirmed a positive relationship between psychological meaningfulness, work engagement and organisational commitment. Further, psychological meaningfulness predicts work engagement, whilst psychological meaningfulness and work engagement predict organisational commitment. Practical/managerial implications: Employers identifying their employees’ commitment patterns and mapping out strategies for enhancing those that are relevant to organisational goals will yield positive work outcomes (e.g. employees who are creative, seek growth or challenges for themselves. Contribution/value-add: This study contributes to the literature through highlighting the impact that meaningful work has on sustaining employee commitment to the organisation.

    According to the theory of work craving, a workaholic has a craving for self-worth compensatory incentives and an expectation of relief from negative affect experienced through neurotic perfectionism and an obsessive-compulsive style of working. Research has shown that workaholism and work engagement should be considered as two distinct work styles with different health consequences. However, the mechanisms underlying the adoption of these work styles have been neglected. The present study proposes that work craving and work engagement are differentially associated with self-regulatory competencies and health. In particular, we expected that the working styles mediate the relationships between emotional self-regulation and health. In the cross-sectional study, 469 teachers from German schools completed online administered questionnaires. By means of structural equation modeling, we tested two indirect paths: a) from self-relaxation deficits via work craving to poor health and b) from self-motivation competencies via work engagement to good health. As expected, we found evidence that a) the negative relationship of self-relaxation deficits on health was partially mediated by work craving and b) the positive relationship of self-motivation competencies on health was partially mediated by work engagement. The present study emphasizes the importance of self-regulation competencies for healthy or unhealthy work styles. Whereas work craving was associated with a low ability to down-regulate negative emotions and poor health, work engagement was associated with a high ability to up-regulate positive emotions and good health.

    The Australian National Hazard Exposure Worker Surveillance (NHEWS) Survey 2008 was a cross-sectional survey undertaken by Safe Work Australia to inform the development of exposure prevention initiatives for occupational disease. This is a descriptive study of workplace exposures. To assess the occupational and demographic characteristics of workers reporting exposure to wet work. Computer-assisted telephone interviews were conducted with 4500 workers. Two wet work exposure outcomes (frequent washing of hands and duration of time spent at work with the hands immersed in liquids) were analysed. The response rate for the study was 42.3%. For hand-washing, 9.8% [95% confidence interval (CI) 8.9-10.7] reported washing their hands more than 20 times per day. For immersion of hands in liquids, 4.5% (95% CI 3.9-5.1) reported immersion for more than 2 hr per day. Females were more likely to report exposure to frequent hand-washing than males [odds ratio (OR) 1.97, 95% CI 1.49-2.61]. Workers in the lowest occupational skill level jobs were more likely to report increased exposure to hands immersed in liquids than those in the highest (OR 6.41, 95% CI 3.78-10.88). Workers reporting skin exposure to chemicals were more likely to report exposure to hand-washing (OR 3.68, 95% CI 2.91-4.66) and immersion of the hands in liquids (OR 4.09, 95% CI 2.92-5.74). Specific groups of workers reported high levels of exposure to wet work. There were differences between the profiles of workers reporting frequent hand-washing and workers reporting increased duration of exposure to hands immersed in liquids. We also found a high correlation between wet work and chemical exposure. © 2011 John Wiley & Sons A/S.

  14. Technocrats and nuclear politics. The influence of professional experts in policy-making

    International Nuclear Information System (INIS)

    Massey, Andrew

    1988-01-01

    The role of technical experts, especially scientists and engineers, in the development of Britain's civil nuclear energy policy is analysed. It is proposed that civil initiatives came from the integration of technical professions within the bureaucracy of government and quasi-governmental organisations involved in the formulation and implementation of policy. Organisational logic and professional motivation encouraged policies which would lead to occupational autonomy. The first three chapters develop the concept of technical professionalism, Chapters 4-7 then focus on the technocrat's role in providing a spur from their positions within the policy community's bureaucracies that drives top-level policy decisions. These functions are examined in more detail using two case studies, the first concerned with the evolution of British Nuclear Fuels Ltd., the second with the Inquiry (in 1977) into the proposal by BNFL to extend its Windscale site (now known as Sellafield) to build the Thermal Oxide Reprocessing Plant.

    1983-01-01

    The results are presented of a study to evaluate the collective dose commitment to the population of the European Community from effluents released by the nuclear industry within the EC in 1978. Airborne and liquid effluent discharge data have been taken from published sources, and computer modelling techniques have been used to predict the transfer of radioactivity through the environment to man. The collective dose commitments due to discharges from each nuclear installation have been evaluated and the comparative significance of individual radionuclides and their pathways to man have been considered. Airborne releases resulted in an estimated collective effective dose equivalent commitment of 95 man Sv, the major part of which is due to carbon-14 from both power stations and reprocessing plants. The collective effective dose equivalent commitment from liquid effluents is estimated to be 408 man Sv, mostly due to caesium-137 and other radionuclides from the Sellafield (formerly Windscale) reprocessing plant...

    The first nuclear reactors at Sellafield went critical in 1951 and fuel reprocessing commenced shortly afterwards. As the nuclear programme expanded, reprocessing increased and there was an associated increase in discharges to the environment. An initial environmental monitoring programme was formulated on the basis of research and assessment of the likely behaviour of radionuclides. In addition to the routine process sources there were also incidents that gave rise to acute releases of radioactivity to the environment. Of key significance were: the Windscale fire, 1957; short-cooled fuel reprocessing, 1981; and discharge of contaminated solvent, 1983. All of these incidents added to the requirements for environments for environmental monitoring. The monitoring programme has evolved over a period of more than 50 years. (N.C.)

  17. Evaluation of experimental studies on technetium transfers to sediments and benthic marine species, and comparison with in situ data

    To obtain basic information for the evaluation of the radiological impact of technetium (Tc) on the marine environment, investigations are performed by different laboratories. Technetium is not a natural element and the main source of production is the nuclear fuel cycle. Under anoxic conditions, in presence of reducing sediments, the distribution coefficients are very high (Ksub(D)=10 3 ). Concentration factors from water to species are mostly very low (FC 1 to 10); however, concentration factors up to 1000 have been observed for a few species such as macrophytic brown algae, worms and lobster. Biochemical analysis shows that Tc is bound with protein. The transfer factors between sediment and species are very low (FT 99 Tc concentrations in species collected near the La Hague and Windscale (Sellafield) reprocessing plants confirm the experimental studies. Since sea water is likely to be an oxydant environment, technetium appears as a conservative element [fr

  18. Communicating risk: news media reportage of a significant nuclear contamination incident in the UK

    Walker, G.P.; Macgill, S.M.

    1988-02-01

    The way the mass media reported a controversial discharge incident at British Nuclear Fuel's reprocessing plant at Sellafield in Cumbria in November 1983 is discussed. Apart from the Windscale fire in 1957 this was the most serious radiation incident at any nuclear installation in the United Kingdom. The aim of the study was to use that incident to develop a more complete understanding of the way information about risk is communicated through the news media. Two issues, in particular, are assessed. First, the accuracy of the reports of events and how factual, technical or scientific aspects of risk are portrayed through the news media. Secondly, risk evaluation is studied: what value judgements are made, what sentiments of alarm, danger and hazard are presented. (author)

  19. The radiation exposure of the UK population from liquid effluents discharged from civil nuclear installations in the UK in 1978

    1982-04-01

    The collective effective dose equivalent commitment to the UK population from routine liquid discharges by civil nuclear establishments during 1978 has been estimated at 134 man Sv. The major pathway considered in the assessment was the consumption of seafoods, because most discharges were made directly to sea. Over 90% of this collective dose commitment will be delivered within a few years of the discharges, and caesium-137 from the nuclear fuel reprocessing facility at Windscale (now known as Sellafield) will have made the main contribution to this commitment. These discharges were primarily due to corrosion of nuclear fuel during storage at the reprocessing plant, and there is no simple relationship between the level of collective dose commitment and the amount of energy generated by nuclear means during 1978.

    The Work Coordination Engine (WCE) is a Java application integrated into the Service Management Database (SMDB), which coordinates the dispatching and monitoring of a work order system. WCE de-queues work orders from SMDB and orchestrates the dispatching of work to a registered set of software worker applications distributed over a set of local, or remote, heterogeneous computing systems. WCE monitors the execution of work orders once dispatched, and accepts the results of the work order by storing to the SMDB persistent store. The software leverages the use of a relational database, Java Messaging System (JMS), and Web Services using Simple Object Access Protocol (SOAP) technologies to implement an efficient work-order dispatching mechanism capable of coordinating the work of multiple computer servers on various platforms working concurrently on different, or similar, types of data or algorithmic processing. Existing (legacy) applications can be wrapped with a proxy object so that no changes to the application are needed to make them available for integration into the work order system as "workers." WCE automatically reschedules work orders that fail to be executed by one server to a different server if available. From initiation to completion, the system manages the execution state of work orders and workers via a well-defined set of events, states, and actions. It allows for configurable work-order execution timeouts by work-order type. This innovation eliminates a current processing bottleneck by providing a highly scalable, distributed work-order system used to quickly generate products needed by the Deep Space Network (DSN) to support space flight operations. WCE is driven by asynchronous messages delivered via JMS indicating the availability of new work or workers. It runs completely unattended in support of the lights-out operations concept in the DSN.

  12. Live to work or love to work: work craving and work engagement.

    Directory of Open Access Journals (Sweden)

    Kamila Wojdylo

    Full Text Available OBJECTIVE: According to the theory of work craving, a workaholic has a craving for self-worth compensatory incentives and an expectation of relief from negative affect experienced through neurotic perfectionism and an obsessive-compulsive style of working. Research has shown that workaholism and work engagement should be considered as two distinct work styles with different health consequences. However, the mechanisms underlying the adoption of these work styles have been neglected. The present study proposes that work craving and work engagement are differentially associated with self-regulatory competencies and health. In particular, we expected that the working styles mediate the relationships between emotional self-regulation and health. METHODS: In the cross-sectional study, 469 teachers from German schools completed online administered questionnaires. By means of structural equation modeling, we tested two indirect paths: a from self-relaxation deficits via work craving to poor health and b from self-motivation competencies via work engagement to good health. RESULTS: As expected, we found evidence that a the negative relationship of self-relaxation deficits on health was partially mediated by work craving and b the positive relationship of self-motivation competencies on health was partially mediated by work engagement. CONCLUSIONS: The present study emphasizes the importance of self-regulation competencies for healthy or unhealthy work styles. Whereas work craving was associated with a low ability to down-regulate negative emotions and poor health, work engagement was associated with a high ability to up-regulate positive emotions and good health.

    Full Text Available When the tide of unemployment hit the USA and Europe, in Japan the opposite phenomenon occurs. In 2002, in Japan deaths were recorded because of excessive works. In this country, the phenomenon of death because of excessive works is called Karoshi. Karoshi is common in Japan.  It becomes deadly syndrome as a consequence of long hours works. The debate about deaths from excessive work already sticking out in Japan since the 70s. The first official case of Karoshi was reported in 1969 when a 29-year-old male worker died because of stroke. It is estimated over ten thousand workers died each year due to death by brain and stroke caused by an overload work. Karoshi often happen to male workers dominantly. The main cause of karoshi is stress due to high pressure in the work environment, and work habits of exceeding a  standard of normal working time (8 hours. In addition, their extra time to work is imbalance with and the salary they earn. In its development, the phenomenon of karoshi contributes to the term salaryman and workaholic.

    Gay Renouf has opted for a work/life balance; with a chemistry degree she joined the Saskatchewan Research Council out of graduate school in 1986. She first worked on understanding surfactants in emulsions and then dealt more with petroleum engineering issues like pipeline specifications. She is looking at waterfloods in heavy and medium gravity pools and has discovered factors helping to produce heavy oil waterfloods. But all Renouf's life is not devoted to her work: she has been working part-time, spending her free time being a parent, training for marathons and being a running coach. Renouf believes that her passion for running is consistent with her work as a scientist.

    2015-06-01

    The knowledge surrounding nurses' work motivation is currently insufficient, and previous studies have rarely taken into account the role of many influential background factors. This study investigates the motivation of Estonian nurses in hospitals, and how individual and organisational background factors influence their motivation to work. The study is quantitative and cross-sectional. An electronically self-reported questionnaire was used for data collection. The sample comprised of 201 Registered Nurses working in various hospital settings in Estonia. Data were analysed using descriptive statistics, two-sample Wilcoxon rank-sum (Mann-Whitney) test, Kruskal-Wallis equality-of-populations rank test and Spearman's correlation. Both extrinsic and intrinsic motivations were noted among hospital nurses. Nurses were moderately externally motivated (M = 3.63, SD = 0.89) and intrinsically strongly motivated (M = 4.98, SD = 1.03). A nurses' age and the duration of service were positively correlated with one particular area of extrinsic work motivation, namely introjected regulation (p motivation (p = 0.016) and intrinsic work motivation (p = 0.004). The findings expand current knowledge of nurses' work motivation by describing the amount and orientation of work motivation among hospital nurses and highlighting background factors which should be taken into account in order to sustain and increase their intrinsic work motivation. The instrument used in the study can be an effective tool for nurse managers to determine a nurse's reasons to work and to choose a proper motivational strategy. Further research and testing of the instrument in different countries and in different contexts of nursing is however required. © 2014 Nordic College of Caring Science.

  16. Making motherhood work

    Directory of Open Access Journals (Sweden)

    Rachel Thomson

    2011-07-01

    Full Text Available Motherhood can be a critical moment in the making of gendered biographies, and in the negotiation of a gendered division of labour within a household. This paper draws on the 'Making of Modern Motherhoods' study, which combined interviews with a diverse group of expectant first time mothers and family case studies in order to build an intergenerational and longitudinal perspective on contemporary mothering situations within the UK. In this paper, the category 'work' is used as a lens through which to encounter new motherhood. After contextualising working motherhood in relation to a sociological literature the paper draws on interviews undertaken with women towards the end of their pregnancy with their first child to reveal something of the emergent collision of working and maternal identities, women's experiences of being pregnant at work including the anticipation and managing of maternity leave. The second part presents a case study, which animates the personal drama involved in reconciling working and maternal commitments, tracing how a woman's feelings about work change over time in negotiation with partner, family and the market. As Sue Sharpe observed in her 1984 book on working mothers, 'full-time mothering has never been accessible to all women in the same way at the same time' (1984: 22. Social class, locality and migration shape a range of cultures of mothering within which work features very differently. Divisions exist between women who share a generational location as well as between women of different generations. This complexity is revealed through a juxtaposition of the voices of mothers and grandmothers, which show how work may both, divide and unite women in the project of motherhood.

    Full Text Available You need to look after your body when you are at work. This not only prevents you from being injured but it also prevents you from living the remainder of your life with a long-term injury. If you do get injured at work, it may reduce your ability to continue to do that job – which means you might not be able to bring the same amount of money home to support your family. Therefore, anything you can do to protect yourself from injury is important and you must prioritise your health and safety at all times while at work.

    2007-12-01

    It is argued that one of the factors limiting the understanding of return to work (RTW) following work disability is the use of measurement tools that do not capture a complete picture of workers' RTW experiences. To facilitate the investigation of RTW, the current authors proposed a developmental conceptualization of RTW, which argues for an expanded awareness that encompasses four phases: off work, work reintegration, work maintenance and advancement. This paper reports on work undertaken with the aim of operationalizing the conceptualization. A review of the RTW and related literature, with databases searched including PubMed, EconLit, and PsycInfo. We began by extracting details of RTW instruments used by previous researchers. We then interpreted these within the context of the phases of RTW. Using the International Classification of Functioning, Disability, and Health (ICF) to inform our thinking and coding structure, we conceptualized phase-based RTW outcomes and categorized them as 'tasks and actions', 'contextual' or 'process driven'. Iteratively, we reviewed existing instruments for their use as measures of RTW. Where gaps in instrumentation were found, the wider vocational and career assessment literature was searched for instruments that could be adapted for use in RTW research. Results indicate that, although numerous research instruments have been used to assess RTW, within the scientific literature some important dimensions of RTW lack instrumentation. In particular, we found that outcomes such as goal setting, motivation, expectation, job seeking, work maintenance, and career advancement require operationalization. Amongst the outcomes had been operationalized, we found considerable variation in conceptual development and application. The lack of consistency and comprehensiveness of RTW measurement is one of the factors compromising the advancement of the field of RTW research. It is suggested that a more complete and psychometrically sound array of

    At the request of Electricite de France (EDF) and Framatome, the Nuclear Protection Evaluation Centre (CEPN) developed a three-year research project, between 1991 and 1993, to evaluate the impact of various work management factors that can influence occupational exposures in nuclear power plants (NPPs) and to assess the effectiveness of protective actions implemented to reduce them. Three different categories of factors have been delineated: those linked to working conditions (such as ergonomic of work areas and protective suits), those characterizing the operators (qualification, experience level, motivation, etc.). In order to quantify the impact of these factors, a detailed survey was carried out in five French NPPs, focusing on three types of operations: primary valves maintenance, decontamination of reactor cavity, and specialized maintenance operations on the steam generator. This survey was augmented by a literature review on the influence of {open_quotes}hostile{close_quotes} environment on working conditions. Finally, a specific study was performed in order to quantify the impact of various types of protective suits used in French nuclear installations according to the type of work to be done. All of these factors have been included in a model aiming at quantifying the effectiveness of protection actions, both from dosimetric and economic point of views.

    At the request of Electricite de France (EDF) and Framatome, the Nuclear Protection Evaluation Centre (CEPN) developed a three-year research project, between 1991 and 1993, to evaluate the impact of various work management factors that can influence occupational exposures in nuclear power plants (NPPs) and to assess the effectiveness of protective actions implemented to reduce them. Three different categories of factors have been delineated: those linked to working conditions (such as ergonomic of work areas and protective suits), those characterizing the operators (qualification, experience level, motivation, etc.). In order to quantify the impact of these factors, a detailed survey was carried out in five French NPPs, focusing on three types of operations: primary valves maintenance, decontamination of reactor cavity, and specialized maintenance operations on the steam generator. This survey was augmented by a literature review on the influence of open-quotes hostileclose quotes environment on working conditions. Finally, a specific study was performed in order to quantify the impact of various types of protective suits used in French nuclear installations according to the type of work to be done. All of these factors have been included in a model aiming at quantifying the effectiveness of protection actions, both from dosimetric and economic point of views

    Are you a CERN cyclist? If so, join the Bike 2 Work competition that has just started! The more kilometres you travel by bike, the closer you’ll get to winning…   Yngve Inntjore Levinsen works at CERN, in the BE Department, and is one of the many people who travel to work by bike. Convinced by the benefits and the well-being that this mode of transport brings, he decided to promote it by running a competition. “Everyone working at CERN can participate,” says Yngve. “They just need to sign up on the competition website, or via their Facebook login. Then, participants simply have to report regularly the number of kilometres they cover by bike, travelling between home and work, or during the day between different points at CERN. ” The competition began on 1 March and will last all year long. The 2012 results will be announced at the end of the year. Of course, the winner will be the cyclist who has travelled the most kilometres during the ...

    Bonder, Bette R; Bazyk, Susan; Reilly, Bridget; Toyota, Jan

    2005-01-01

    The purpose of this paper is to describe women's work in Maya communities in the Guatemala Highlands, along with some of the trends accompanying the rapid societal change there. Over the course of six years, observations and interviews focused on two specific groups of women. The first were traditional, home-based women, the second, teachers in a primary school. Resulting transcripts and field notes were analyzed by the researchers to identify themes related to the women's perspectives on work, the patterns of their work activities, and the importance of work in their lives. Women who had been interviewed were asked to reflect on the themes identified. All the women engaged in paid work activities and were responsible for obligatory tasks in the home. The traditional group preserved the tradition of weaving, but remained largely illiterate, while the emerging group was literate, but did not learn to weave. Cultural change is both positive and negative, as described by these women. It is important to understand the particular values of the culture, and to recognize that these may not conform to Western (that is to say U.S.) beliefs and practices.

    A reconfigurable autonomous workstation includes a multi-faced superstructure including a horizontally-arranged frame section supported on a plurality of posts. The posts form a plurality of vertical faces arranged between adjacent pairs of the posts, the faces including first and second faces and a power distribution and position reference face. A controllable robotic arm suspends from the rectangular frame section, and a work table fixedly couples to the power distribution and position reference face. A plurality of conveyor tables are fixedly coupled to the work table including a first conveyor table through the first face and a second conveyor table through the second face. A vision system monitors the work table and each of the conveyor tables. A programmable controller monitors signal inputs from the vision system to identify and determine orientation of the component on the first conveyor table and control the robotic arm to execute an assembly task.

    YuLeung To, Eric; Abbott, Kathy; Foster, Dale S; Helmer, D'Arcy

    2016-01-01

    Impairments in working memory are typically associated with impairments in other cognitive faculties such as attentional processes and short-term memory. This paper briefly introduces neurofeedback as a treatment modality in general, and, more specifically, we review several of the current modalities successfully used in neurofeedback (NF) for the treatment of working memory deficits. Two case studies are presented to illustrate how neurofeedback is applied in treatment. The development of Low Resolution Electromagnetic Tomography (LORETA) and its application in neurofeedback now makes it possible to specifically target deep cortical/subcortical brain structures. Developments in neuroscience concerning neural networks, combined with highly specific yet practical NF technologies, makes neurofeedback of particular interest to neuropsychological practice, including the emergence of specific methodologies for treating very difficult working memory (WM) problems.

    1988-02-01

    Information on acute intoxications during work in the Netherlands has been gathered from 4 sources during a 1-year period: 1. The registration of occupational accidents of the Directorate-General of Labour, by reviewing reports on accidents involving chemicals; 2. The Netherlands Poison Control Centre of the National Institute for Public Health and Environmental Hygiene, by tracing back consulting physicians; 3. The Dutch Centre for Health Care Information, by searching their data base for hospital admissions with relevant admission diagnoses and 4. A large Occupational Health Service, which for this purpose recorded incident cases in the population under care. During the period of investigation 5 deaths were reported: 1 case of hydrogen cyanide intoxication, 1 case of carbon dioxide intoxication, and 3 cases of hydrogen sulfide intoxication in combination with oxygen deficiency (nearby a liquid manure tank). At least 690 (supposed) acute intoxications during work occurred, which in 84 cases resulted in hospital admission. The total number of hospital admissions for supposed unintentional acute intoxications by chemicals, usually encountered in workplaces, in the Netherlands in 1984 was at least 477. Substances most often involved belonged to the groups of pesticides, lung and/or skin irritant liquids/vapors/gases and asphyxiants. The working branches most often involved were agriculture and market gardening sectors, (chemical) industries, repair and retail trade and some governmental services (police, fire brigade, defense personnel). The results show considerable underreporting in official statistics on acute intoxications during work.

    The precaution principle is applied in the example of The nuclear facilities in the United Kingdom, Windscale reactor and the Sellafield reprocessing plant. In the first case, an interpretation mistake in the behaviour of sediments in Irish Sea leads to a pollution by plutonium 239, and finally the admissible contamination of sediments became a possible ingestion of plutonium in atmosphere because of transport of this radioisotope from the sediments to the surface waters and then to atmosphere with this possibility of ingestion by man and ingestion is a more severe pollution than contamination. The second example is the difference of behaviour of Cesium 137 in front of acid soils or clayey soils, difference that the researchers did not see in United Kingdom around Sellafield plant but the Chernobyl accident brought to the fore this difference of behaviour. These examples proved if it was needed that scientific knowledge is uncomplete and consequently the precaution principle is highly required. Furthermore, the cases of the blood transfusion and the Aids virus, the impact on health of power lines and the ozone layer are also reviewed to enlight this precaution principle. (N.C.)

    Air and soil pollution, increased water discharge and energy consumption, forest and plant fires are often caused by low general and ecological culture. Nuclear power has long been a main target of environmental campaigners, in Europe as well as America. The past 200 years have seemed to reinforce their case: the Chernobyl accident was compounded by fears that a similar disaster could occur in any of the antiquated graphite-cooled reactors, revelations that leaks and mishaps from Windscale/Sellafield were far worse than originally reported, campaigns against reprocessing in Germany and Japan and alarming data on nuclear hazards from sunken Russian submarines and leaking waste storage tanks. The International Center for Environmental Safety of Minatom of Russia (ICES MR) is an autonomous non-commercial organisation. The mission of the Center is to assist in environment improving and consolidation of international contacts in environmental safety, to assist in development of te positive public perception of nuclear power. We attach great significance to interaction with the public, administrations of regions and State Duma deputies. Very often a dread of radiation and protests against nuclear power development are caused by lack or insufficiency of information concerning what is radiation, how it influences a human being and nature, where is real and not made-up danger. Here it is very important to organize work with the youth. Our first experience was a Children Ecological Olympiad 'Sozvezdie'. The Olympiad was held in the Russian Cosmonauts Training Center in Zvezdny gorodok in May 2001. It has a success and showed the strong interest of schoolchildren, their parents and teachers in environmental problems, in the nuclear power as an environment friendly energy production. Together with the UNESCO department and the Youth Department of Russian Nuclear Society for youth interaction we have prepared proposals concerning establishing Youth Environmental Centers in

    1998-01-01

    The IAEA has, during the last three years, been working intensively on PSA applications. The draft TECDOC prepared during these activities, ''PSA Applications'' is summarized in this paper. Actual events at nuclear facilities provide an important basis to compare PSAs with reality. PSA based operational event analysis therefore can be used to evaluate the importance of operational events from a risk perspective but also can contribute to validating and enhancing PSAs and to continuously check whether or not the PSA models are adequate, appropriate and complete. The work of the IAEA in this area is therefore summarized as well. In a companion paper, titled ''Towards a credible PSA fit for applications'', two specific aspects regarding the quality of the PSA to be used are discussed in detail, namely the Living PSA concept, which ensures that the PSA reflects actual design and operational features and Quality Assurance for PSA.

    The Transport Working Group was formed on The 10th November 1999 to study all means of transport required for the installation of the LHC machine in the existing tunnel infrastructure of the LEP. The Groups' main aim is to assess the feasibility of transport propositions offered for the handling to be carried out in the new LHC environment. The working group is composed of Mechanical Engineers, Physicists and Transport Engineers, as well as specialists who are invited to the meetings for their advice on certain aspects of the forthcoming installation. In May 2001 the group mandate was revised to include all means of transport, including surface transport as well as that required in the tunnel. The installation phase requires the handling of approximately 100,000 tonnes of delicate experimental equipment with very strict limits in terms of acceleration and shock loading. This must be installed via vertical shafts up to 140 meters deep.

    This memo summarizes the aerodynamic drag scoping work done for Goodyear in early FY18. The work is to evaluate the feasibility of using Sierra/Low-Mach (Fuego) for drag predictions of rolling tires, particularly focused on the effects of tire features such as lettering, sidewall geometry, rim geometry, and interaction with the vehicle body. The work is broken into two parts. Part 1 consisted of investigation of a canonical validation problem (turbulent flow over a cylinder) using existing tools with different meshes and turbulence models. Part 2 involved calculating drag differences over plate geometries with simple features (ridges and grooves) defined by Goodyear of approximately the size of interest for a tire. The results of part 1 show the level of noise to be expected in a drag calculation and highlight the sensitivity of absolute predictions to model parameters such as mesh size and turbulence model. There is 20-30% noise in the experimental measurements on the canonical cylinder problem, and a similar level of variation between different meshes and turbulence models. Part 2 shows that there is a notable difference in the predicted drag on the sample plate geometries, however, the computational cost of extending the LES model to a full tire would be significant. This cost could be reduced by implementation of more sophisticated wall and turbulence models (e.g. detached eddy simulations - DES) and by focusing the mesh refinement on feature subsets with the goal of comparing configurations rather than absolute predictivity for the whole tire.

    Thousands of improperly abandoned or decommissioned oil and gas wells are threatening the purity of Ontario's source water. This presentation discussed an abandoned works program developed by the Ontario Ministry of Natural Resources. The abandoned works program was established in 2005 in order to plug old oil and gas wells. The program was designed to create a list of abandoned wells, develop a coherent policy, and formulate procurement and contracting protocols. Abandoned wells are defined as wells drilled prior to 1963 with no operator other than the current landowner. There are currently over 200 prioritized wells on the list. Twenty-six contracts have been issued for a total of 33 wells, and 19 wells have been plugged since the program's field operations began in 2006. However, the program is often challenged by the difficulties associated with determining where the wells are located. Many of the wells have been cut off and buried, and access is often dependent on weather conditions and road restrictions. There is also a shortage of contractors who have experience working with older wells. It was concluded that the program will expand by obtaining further funding and modifying its qualification criteria. tabs., figs

  12. Gender and Working Life

    2011-11-01

    Full Text Available Analysis of occupational segregation by sex and gendered practices in the workplace are complex, multidimensional and contested fields of research and academic discourse. Since the 1960s, we have seen a rapid growth in both quantity and quality of academic work in this field. Earlier simplistic main (male stream as well as straightforward feminist explanations has been roundly criticised and deconstructed. It is now clear that the study of gender relations in working life is far more complicated than it was believed decades ago. The central question in gender research is how gendered structures – in which men in general have more power, more prestigious positions and higher pay – are reproduced in a world in which demography, economy, production, education and therefore society and family have changed over time. Nordic countries represents an interesting geographical arena to examine gender relations in working life, because many factors, which have been seen in other countries as causes for female subordination, appear in other forms. At present, the labour force participation rate of women in Nordic countries is nearly equal to that of men, but there are still substantial differences. Women are better educated than men, and also, to a large extent unionised. Although these factors make Nordic women stand out globally, gender equality at work or at home has not yet been achieved. The male breadwinner is still a societal norm and a construct, which conditions the behaviour of organisations and individuals in many circumstances in working life. This influence can be obvious or obscure. From the 1990s, research has turned to focus also on the fate of the male workforce during deindustrialisation and global restructuring. Participation rate of men in gainful employment have diminished in all industrialised countries (Crouch; 1999, Walby; 1997. Nordic countries are not an exception to this trend.

    This paper describes the control and limitation of dose uptake to operators during the early stages of decommissioning of the Windscale Piles. This was achieved by careful planning, the use of inactive trials. thoughtful use of remote handling techniques and review and feedback of information. Built between 1947 and 1950, the Windscale Piles were shut down following the Windscale Incident in 1957. UKAEA Government Division are now undertaking the early stages of decommissioning of these facilities, removing material from the air and water ducts and preparing for subsequent core removal. As part of the overall strategy of UKAEA GD, this work is being carried out using contract staff including the use of a Managing Agency, W S Atkins (Northern). Decommissioning utilizes the same means of dose reduction and control as any other nuclear operation although sometimes in novel ways. In the Windscale Piles, fully remote operations have been used to remove fuel and debris from the environs of the core which was damaged during the 1957 incident. Much use has also been made of training in mock-up facilities allowing manual techniques to be used for some jobs. The implications of using various different contractors rather than an in-house team is also discussed. It is concluded that decommissioning of major facilities can be carried out within acceptable dose uptake criteria by utilising both novel and adaptations of traditional, active handling techniques.

    Three experiments investigated the role of working memory in various aspects of thinking in chess. Experiment 1 examined the immediate memory for briefly presented chess positions from master games in players from a wide range of abilities, following the imposition of various secondary tasks designed to block separate components of working memory. Suppression of the articulatory loop (by preventing subvocal rehearsal) had no effect on measures of recall, whereas blocking the visuospatial sketchpad (by manipulation of a keypad) and blocking the central executive (by random letter generation) had equivalent disruptive effects, in comparison with a control condition. Experiment 2 investigated the effects of similar secondary tasks on the solution (i.e., move selection) of tactical chess positions, and a similar pattern was found, except that blocking the central executive was much more disruptive than in Experiment 1. Experiment 3 compared performance on two types of primary task, one concerned with solving chess positions as in Experiment 2, and the other a sentence-rearrangement task. The secondary tasks in each case were both designed to block the central executive, but one was verbal (vocal generation of random numbers), while the other was spatial in nature (random generation of keypresses). Performance of the spatial secondary task was affected to a greater extent by the chess primary task than by the verbal primary task, whereas there were no differential effects on these secondary tasks by the verbal primary task. In none of the three experiments were there any differential effects between weak and strong players. These results are interpreted in the context of the working-memory model and previous theories of the nature of cognition in chess.

I have assisted in characterizing fibers pulled from a spacecraft, a white fibrous residue discovered in a jet refueler truck, brown residue from a plant habitat slated for delivery to the ISS (International Space Station), corrosion on a pipe from a sprinkler, and air filtration material brought back from the ISS. I also conducted my own fiber study in order to practice techniques and further my understanding of background concepts. Furthermore, I had the opportunity to participate in diverse work assignments, where I was assigned to work with other branches of the engineering department for 1-2 days each. The first was in the Materials Science branch where I participated in the construction of the plant habitat intended for use in research aboard the ISS. The second was in the Testing Design branch where I assisted with tensile and hardness testing of over 40 samples. In addition, I have had the privilege to attend multiple tours of the NASA KSC campus, including to the Astronaut Crew Quarters, the VAB (the main area, the Columbia room, and the catwalk), the Visitor Center housing the shuttle Atlantis, the Saturn-V exhibit, the Prototype laboratory, SWAMP WORKS, the Shuttle Landing Facility, the Crawler, and the Booster Fabrication Facility (BFF). Lastly, much of my coursework prepared me for this experience, including numerous laboratory courses with topics diverse as chemistry, physics, and biology.

    Full Text Available To encourage worker productivity, companies routinely adopt policies requiring employees to delay gratification. For example, offices might prohibit use of the internet for personal purposes during regular business hours. Recent work in social psychology, however, suggests that using willpower to delay gratification can negatively impact performance. We report data from an experiment where subjects in a Willpower Treatment are asked to resist the temptation to join others in watching a humorous video for 10 minutes. In relation to a baseline treatment that does not require willpower, we show that resisting this temptation detrimentally impacts economic productivity on a subsequent task.

    With the development of new technologies for simultaneous analysis of many genes, transcripts, or proteins (the "omics" revolution), it has become common to outsource parts of the experimental work. In order to maintain the integrity of the research projects, it is important that the interphase between the researcher and the service is further developed. This involves robust protocols for sample preparation, an informed choice of analytical tool, development of standards for individual technologies, and transparent data analysis. This chapter introduces some of the problems related to analysis of RNA samples in the "omics" context and gives a few hints and key references related to sample preparation for the non-specialist.

  3. Work hazard prevention plans

    2009-01-01

    The prevention of industrial risks is a constantly evolving discipline that has changed considerable in the last 25 years. The Cofrentes Nuclear Power Plants has always been operated with a clear policy favoring prevention by supporting the principle of its integration, i. e., that the hierarchical functional organization of the company make sure that industrial risk prevention is effective and that health and safety standards are met. The historical evolution of occupational safety in the Cofrentes Nuclear Power Plant shows a a clear trend towards improvement and is the results of many years of hard work and effort by the plants own and contractor personnel in the field of industrial risk prevention.

    The repair of faulty elements in the cryogenic distribution line is making great progress in building 927 at CERN. While many of us were relaxing over the two-week Christmas break, the team repairing elements of the LHC cryogenic distribution line - or QRL - continued working, keeping the repair schedule on course for completion by the end of March. Pipe elements with faulty sliding tables are being repaired by the ICS consortium, in charge of installing the cryo-magnets in their cryostats. This team began repairs at the beginning of November, fixing 10 elements a week (See Bulletin 42/2004 from 11 October 2004). However, during the five-week winter shutdown of the magnet test facility they are being assisted by 20 personnel who normally work on magnet testing. With the extra help a repair rate of five pipe elements a day has been reached - 25 elements a week - thanks to the remarkable effort of the ICS personnel led by Patrick Voisin, the DBS personnel assuring the transport and handling of the elements, an...

    The workshop of 26-27 june 2000, on nuclear power Plant LIfe Management (PLIM), also included working groups in which major issues facing PLIM activities for nuclear power plants were identified and discussed. The third group was on Business. The discussion concerned the following points: There are concerns about retaining experienced/trained personnel, and maintaining a good working relationship among them, as well as about the closure of research facilities, the reduction in staff numbers under increasing economic pressure and the lack of new nuclear power plant constructions. The marginal cost of producing electricity is lower for most existing nuclear power plants than for almost all other energy sources. Refurbishment costs are usually relatively small compared with new investments. The ongoing regulatory reform of the electricity market will bring increasing competition. Although PLIM has been carried out in many countries with favourable results, there are still uncertainties which affect business decisions regarding financial and market risks in PLIM activities. Recommendations were made. (author)

    Full Text Available Article in English, Abstracts in Spanish and English. Humboldt wrote about Mexico from the perspective of a scientific explorer and naturalist. His works include his diaries, the Essai politique sur le royaume de la Nouvelle-Espagne, the Tablas géograficas, the Vues des Cordillères and a geographic atlas. Concerning the scientific aspect, the lack of a section on Mexico in the Relation historique is not a real deficit, since this can be found in the Essai. But only the diaries and letters from the journey, both published by the Alexander-von-Humboldt Research Centre, Berlin, can be considered an adequate substitute.The following will show the origin of Humboldt's writings on Mexico, offer historical and bibliographical facts and present the publications "Beiträge zur Alexander von Humboldt-Forschung", as well as Humboldt’s handwritten estate as far as they are available to us.

  13. Working Group Report: Sensors

    Energy Technology Data Exchange (ETDEWEB)

    Artuso, M.; et al.,

    2013-10-18

    Sensors play a key role in detecting both charged particles and photons for all three frontiers in Particle Physics. The signals from an individual sensor that can be used include ionization deposited, phonons created, or light emitted from excitations of the material. The individual sensors are then typically arrayed for detection of individual particles or groups of particles. Mounting of new, ever higher performance experiments, often depend on advances in sensors in a range of performance characteristics. These performance metrics can include position resolution for passing particles, time resolution on particles impacting the sensor, and overall rate capabilities. In addition the feasible detector area and cost frequently provides a limit to what can be built and therefore is often another area where improvements are important. Finally, radiation tolerance is becoming a requirement in a broad array of devices. We present a status report on a broad category of sensors, including challenges for the future and work in progress to solve those challenges.

    A working group at a Canada/USA symposium on climate change and the Arctic identified major concerns and issues related to terrestrial resources. The group examined the need for, and the means of, involving resource managers and users at local and territorial levels in the process of identifying and examining the impacts and consequences of climatic change. Climatic change will be important to the Arctic because of the magnitude of the change projected for northern latitudes; the apparent sensitivity of its terrestrial ecosystems, natural resources, and human support systems; and the dependence of the social, cultural, and economic welfare of Arctic communities, businesses, and industries on the health and quality of their environment. Impacts of climatic change on the physical, biological, and associated socio-economic environment are outlined. Gaps in knowledge needed to quantify these impacts are listed along with their relationships with resource management. Finally, potential actions for response and adaptation are presented

    A Natural Analogue Working Group was established by the Commission of the European Communities in 1985. The purpose of this group is to bring together modellers with earth scientists and others, so that maximum benefit can be obtained from natural analogue studies with a view to safe geological disposal of radioactive waste. The first meeting of this group was held in Brussels from November 5 to 7, 1985. The discussions mainly concerned the identification of the modellers' needs and of the earth scientists' capacity to provide for them. Following the debates, a written statement was produced by the Group; this document forms the core of the present Report. Notes and outlines of many of the presentations made are grouped in four appendixes. The valuable contribution of all those involved in the meeting is gratefully acknowledged

  20. Making sustainability work

    International Nuclear Information System (INIS)

    Binswanger, Hans Christoph

    1998-01-01

    Today's economic theory usually neglects the role of nature and environment. To make sustainability work it is, however, essential to (re-)integrate nature into the standard concepts of economics, especially by incorporating natural factors into the production function. It must be acknowledged that economic growth is not (only) the result of technical change but is mainly caused by rising energy-inputs into the economy, and that this is necessarily followed by resource exhaustion and pollution. Therefore, nature must not only be taken into account as a central factor of production but also in the form of environmental quality which is the basis for human quality of life. A numeric example shows that a small, but steady decrease of yearly resource consumption is already apt to redirect the economy on a path of sustainable development

    Brooks, Frederick P., Jr.

    1991-01-01

    The utility of virtual reality computer graphics in telepresence applications is not hard to grasp and promises to be great. When the virtual world is entirely synthetic, as opposed to real but remote, the utility is harder to establish. Vehicle simulators for aircraft, vessels, and motor vehicles are proving their worth every day. Entertainment applications such as Disney World's StarTours are technologically elegant, good fun, and economically viable. Nevertheless, some of us have no real desire to spend our lifework serving the entertainment craze of our sick culture; we want to see this exciting technology put to work in medicine and science. The topics covered include the following: testing a force display for scientific visualization -- molecular docking; and testing a head-mounted display for scientific and medical visualization.

    2002-06-01

    Despite public concern about time pressures experienced by working parents, few scholars have explicitly examined the effects of work time on work-family conflict. The authors developed and tested a model of the predictors of work time and the relationships between time, work interference with family (WIF). and psychological distress. Survey data came from 513 employees in a Fortune 500 company. As predicted, several work and family characteristics were significantly related to work time. In addition, work time was significantly, positively related to WIF, which in turn was significantly, negatively related to distress. The results suggest that work time fully or partially mediates the effects of many work and family characteristics on WIF.

  10. The IAEA at work

    International Nuclear Information System (INIS)

    2004-03-01

    Fifty years ago, Dwight Eisenhower stood before the United Nations to offer both a warning and a vision. The knowledge to build an atomic bomb was in the hands of rival powers and would soon be shared by many countries, the President said. It was time to create a U.N. body that could ensure that the new technology served no military purpose. It was time, moreover, to 'devise methods whereby this fissionable material would be allocated to serve the peaceful pursuits of mankind' in agriculture, medicine and other peaceful activities. Eisenhower foresaw a world safe from the destructive power of atomic fission but gaining from its technological advances. Half a century later, the world continues to witness his foresight through the work of the International Atomic Energy Agency (IAEA). The IAEA aims at four formidable goals: safeguarding nuclear nonproliferation; enhancing the security of nuclear facilities and radioactive materials; ensuring the safety of nuclear technologies; and promoting nuclear science to meet human needs. As the world's 'nuclear watchdog,' the IAEA's impartial inspectorate verifies the peaceful uses of nuclear energy in scores of countries. By joining the Agency's strengthened safeguards system and concluding an Additional Protocol, countries can assure the world-and the IAEA can verify-that their nuclear activities are not used for weapons purposes. True to Eisenhower's vision, the power of the atom is being tapped for many human benefits, especially in the world's less developed nations. Extreme poverty remains a profound problem today: some 1.2 billion people in the developing world survive marginally on less that US$1 per day. Another 2.8 billion struggle on less than US$2 per day. The IAEA is mobilizing nuclear science to help address these pressing needs. From managing water better, to controlling pests and diseases, to protecting the environment, the IAEA is helping poor countries make sizeable advances. At the same time, the IAEA works

    These days physicians' work is characterized by an increase in economic demands, pressure and challenges in establishing a balance between work and family life. The current study investigates the relationship between physicians' job demands and resources, perceived job stress, work-family conflict, work engagement and job satisfaction. 564 clinicians specialising in different medical fields participated in the cross-sectional study. Self-administered questionnaires, including the COPSOQ and the UWES- Scale were administered. Our results illustrated significant relationships between physicians' work engagement and their job satisfaction as well as between job stress and work family conflict. Moreover, perceived job stress moderated the effect of high job demands on work family conflict. In addition, significant gender differences have been found in perceived stress levels, work family conflict and work engagement. This study proves and verified associations between work engagement, work-family conflict, job demands and resources that may influence employees' satisfaction. Implications for both working physicians and hospital management are given.

  12. Proposal Improvements That Work

    Rocketdyne Propulsion and Power, an operating location of Boeing in Canoga Park, California is under contract with NASA's Marshall Space Flight Center (MSFC) in Huntsville, Alabama for design, development, production, and mission support of Space Shuttle Main Engines (SSMEs). The contract was restructured in 1996 to emphasize a mission contracting environment under which Rocketdyne supports the Space Transportation System launch manifest of seven flights a year without the need for a detailed list of contract deliverables such as nozzles, turbopumps, and combustion devices. This contract structure is in line with the overall Space Shuttle program goals established by the NASA to fly safely, meet the flight manifest, and reduce cost. Rocketdyne's Contracts, Pricing, and Estimating team has worked for the past several years with representatives from MSFC, the local Defense Contract Management Command, and the DCAA to improve the quality of cost proposals to MSFC for contract changes on the SSME. The contract changes on the program result primarily from engineering change proposals for product enhancements to improve safety, maintainability, or operability in the space environment. This continuous improvement team effort has been successful in improving proposal quality, reducing cycle time, and reducing cost. Some of the principal lessons learned are highlighted here to show how proposal improvements can be implemented to enhance customer satisfaction and ensure cost proposals can be evaluated easily by external customers.

  13. Doctors in Balzac's work.

    Science.gov (United States)

    Moulin, Thierry

    2013-01-01

    Balzac wrote his novels during a time of great literary and scientific change. Romanticism gave way to the school of realism, of which Balzac could be considered the founder. It was via realism, where both the positive and negative aspects of life were depicted, that doctors naturally gained a much more active role in novels. In conjunction with this was the development of science and medicine, which fascinated Balzac, also leading to the significant and prevalent role of doctors in his works. His fascination with the sciences led to him to gain many acquaintances and much knowledge in the medical domain, especially in neuropsychiatry and physiology. His fictional doctors, such as Desplein and Bianchon, thus demonstrate considerable knowledge of pathology, physiology, and neuropsychiatry. The doctors in Balzac's novels can be grouped into four categories: provincial doctors, Parisian doctors, country doctors, and military doctors. They were most often fictitious representations of real individuals (e.g. Guillaume Dupuytren), and often symbolize schools of thought which were in vogue at the time. In addition to the accurate scientific depiction of doctors, it must be noted that his doctors not only played an active role in clinically assessing their patients, but also had a sociological role in assessing society; it is through his doctors that Balzac gave his opinion of the world in which he lived.

  15. Working the Dark Side

    DEFF Research Database (Denmark)

    Bjering, Jens Christian Borrebye

    A few days after the terror attacks of 9/11, then Vice President Dick Cheney appeared on television with a call for “working the dark side.” While still unclear what this expression entailed at the time, Cheney's comment appears in retrospect to almost have been prophetic for the years to come...... – years where parts of the U.S. Army and intelligence community set up a rampant torture regime all across the world. Yet, the connection between a so-called “dark side,” “working” this “dark side,” and the torture that followed is not a given, but, instead, a consequence of a set of very specific legal......, political, and personal choices in the early years after 9/11. This dissertation is an investigation into how the notion of a “dark side” took form, and of how and why the specific make-up of this“dark side” ended up creating a torture regime which already today seems almost unreal.

    Google Executive Chairman and ex-CEO Eric Schmidt and former SVP of Products Jonathan Rosenberg came to Google over a decade ago as proven technology executives. At the time, the company was already well-known for doing things differently, reflecting the visionary--and frequently contrarian--principles of founders Larry Page and Sergey Brin. If Eric and Jonathan were going to succeed, they realized they would have to relearn everything they thought they knew about management and business. Today, Google is a global icon that regularly pushes the boundaries of innovation in a variety of fields. HOW GOOGLE WORKS is an entertaining, page-turning primer containing lessons that Eric and Jonathan learned as they helped build the company. The authors explain how technology has shifted the balance of power from companies to consumers, and that the only way to succeed in this ever-changing landscape is to create superior products and attract a new breed of multifaceted employees whom Eric and Jonathan dub "smart creat...

  17. Social strategies that work.

    Science.gov (United States)

    Piskorski, Mikołaj Jan

    2011-11-01

    Although most companies have collected lots of friends and followers on social platforms such as Facebook, few have succeeded in generating profits there. That's because they merely port their digital strategies into social environments by broadcasting their commercial messages or seeking customer feedback. To succeed on social platforms, says Harvard Business School's Piskorski, businesses need to devise social strategies that are consistent with users' expectations and behavior in these venues--namely, people want to connect with other people, not with companies. The author defines successful social strategies as those that reduce costs or increase customers' willingness to pay by helping people establish or strengthen relationships through doing free work on a company's behalf. Citing successes at Zynga, eBay, American Express, and Yelp, Piskorski shows that social strategies can generate profits by helping people connect in exchange for tasks that benefit the company such as customer acquisition, marketing, and content creation. He lays out a systematic way to build a social strategy and shows how a major credit card company he advised used the method to roll out its own strategy.

A qualifier, regardless of its form of effective expression, can make a difference in a given context of issuing a value judgment, in relation to the student's performance assessment. In our research we tried to find out what motives students, what determines them to get actively involved in the tasks they are given and the ways we can improve their participation in classes and assignments. In order to have an educated generation we need to have not only well prepared teachers but ones that are open-minded, flexible and in pace with the methodological novelties that can improve the teaching learning process in class. Along the years we have noticed that in classes where students constituted a cohesive group with an increasing degree of interaction between members, the results were better than in a group that did not appreciate team-work. In this article we want to highlight the fact that a teacher can bring to class the appropriate methods and procedures can contribute decisively to the strengthening of the group cohesion and high scores.

    Full Text Available I have been photographing my children, Eden and Emmanuelle since I got pregnant in 2003. I photograph as a mother, from a mother's point of view, showing the different aspects of motherhood as I see them; the beautiful and the ugly, the magic and the frustration, the extremes that live side by side when you are a mother. I try to photograph them all. Crying, sadness, anxiety, mourning the body I will never have again, the woman I will never be again. The strong physical connection to the children, erotic at times, something I found out many mothers experience but do not talk about much. With my images I try to sing a love song to my children, they are my inspiration. Their love, sadness, joy and neediness are for me the most meaningful moments of my life, the moments I want to photograph and preserve. Those images are taken from my life, they are very personal, they are about being a mother, being a child, the intensity of raising a child. This work is about the essence of being human.

    Natural analogue studies have been carried out for several years in the framework of the European Community's R and D programme on radioactive waste; and within its recent fourth five-year programme on 'Management and storage of radioactive waste (1990-94)' the Community is participating in the Oklo study, natural analogue for transfer processes in a geological repository. The Oklo project is coordinated by CEA-IPSN (F) and involves laboratories from several CEA directorates (IPSN, DTA and DCC) which collaborate with other institutions from France: CREGU, Nancy; CNRS, Strasbourg and ENSMD, Fontainebleau. Moreover, institutes from non-EC member States are also taking part in the Oklo study. The second joint CEC-CEA progress meeting of the Oklo Working Group was held in April 1992 in Brussels and gave the possibility of reviewing and discussing progress made since its first meeting in February 1991 at CEA in Fontenay-aux-Roses. About 40 participants from 15 laboratories and organizations coming from France, Canada, Gabon, Japan, Sweden and the USA underline the great interest in the ongoing research activities. The meeting focused on the different tasks within the CEC-CEA Oklo project concerning (i) field survey and sampling, (ii) characterization of the source term, (iii) studies of the petrographical and geochemical system, and (iv) studies of the hydrogeological system and hydrodynamic modelling.

  1. Ansel Adams: early works

    2010-02-01

    Ansel Adams (1902-1984), photographer, musician, naturalist, explorer, critic, and teacher, was a giant in the field of landscape photography. In his images of the unspoiled Western landscape, he strove to capture the sublime: the transcendentalist concept that nature can generate the experience of awe for the viewer. Many viewers are familiar with the heroic, high-contrast prints on high-gloss paper that Adams made to order beginning in the 1970s; much less well known are the intimate prints that the artist crafted earlier in his career. This exhibition focuses on these masterful small prints from the 1920s into the 1950s. During this time period, Adams's printing style changed dramatically. The painterly, soft-focus, warm-toned style of the Parmelian Prints of the High Sierras from the 1920s evolved into the sharp-focus style of the f/64 school of photography that Adams co-founded in the 1930s with Edward Weston and Imogen Cunningham. After World War II, Adams opted for a cooler, higher-contrast look for his prints. Throughout the various styles in which he chose to work, Adams explored the power of nature and succeeded in establishing landscape photography as a legitimate form of modern art.

  2. Maritime Work and Communication

    Full Text Available This paper presents findings from the project "Elastic Systems" under the Danish Center for Human Machine Interaction. The project aims at developing methods for analyzing dynamic maritime work processes and for designing flexible instrument interfaces that will support changing work environments. Here I only address the former issue, the design issues being published elsewhere, e.g. in Andersen(1999 and Andersen & May (2001. More data can be found in Andersen(2000. The purpose of the present paper is twofold: (1 to present characteristics of maritime work and communication, and (2 to suggest a conceptual framework that covers communicative as well as non-communicative acts. The latter purpose is motivated in two ways. Theoretical motivation: we know that language is self-referential, so that it can speak of non-linguistic entities like ships and waves as well as its own properties, such as the correct wording or style. The easiest way to accomplish this is for language to treat both domains in a similar way. The other motivation is more practical: it is a fact that communication and physical actions are interwoven in maritime work, and a theory that builds on a sharp distinction between these two kinds of behaviors will miss this basic characteristic. The data is from a voyage aboard Sally Maersk from Algeciras to Goteborg and back to Rotterdam. We recorded 60 hours of high quality video, and the paper builds upon a 16 hours trip from Felixstowe to Rotterdam, supplemented by data from simulated voyages in the simulator at the Danish Maritime Institute. The conceptual framework is based on Lind 1994 and Lind 2000 and distinguishes between the following types of action types: (1 Prevent(suppress, avoid: if I hadn't done it, then an undesirable state would have developed. Prevent drifting by using auxiliary rudder. (2 Maintain: if I hadn't done it, then a desirable state would have disappeared. Maintain course. (3 Help: a positive state would have

    Heart disease is the main cause of early disability and premature death in Europe. Regular physical activity may prevent heart disease, diabetes, ictus, and obesity. Nevertheless, a certain resistance to a dynamic lifestyle, lack of free time, lack of motivation and other factors are frequently encountered. To stress the importance of physical activity in the prevention of cardiovascular disease. A literature review of the main risk factors for cardiovascular disease was carried out. It has been shown that physical exercise is beneficial to the cardiovascular apparatus and to the bones and joints, by improving some metabolic parameters. Recent studies have shown that a personalized, moderate physical activity should be suggested for primary and secondary prevention, in particular for subjects with coronary artery disease and left ventricular dysfunction. An increase in sports activity and physical exercise at work and at school is recommended so as to improve quality of life and promote home rehabilitation. Some promising experience has already been made among workers and their families with excellent results, as shown by a follow-up period of three years.

    Similarly to related developments such as blended learning and blended care, blended working is a pervasive and booming trend in modern societies. Blended working combines on-site and off-site working in an optimal way to improve workers' and organizations' outcomes. In this paper, we examine the degree to which workers feel that the two defining features of blended working (i.e., time-independent working and location-independent working) enhance their own functioning in their jobs. Blended working, enabled through the continuing advance and improvement of high-tech ICT software, devices, and infrastructure, may be considered beneficial for workers' perceived effectiveness because it increases their job autonomy. However, because blended working may have downsides as well, it is important to know for whom blended working may (not) work. As hypothesized, in a sample of 348 workers (51.7% women), representing a wide range of occupations and organizations, we found that the perceived personal effectiveness of blended working was contingent upon workers' psychological need strength. Specifically, the perceived effectiveness of both time-independent working and location-independent working was positively related to individuals' need for autonomy at work, and negatively related to their need for relatedness and need for structure at work.

    Work capacity correlates weakly to disease concepts, which in turn are insufficient to explain sick leave behavior. With data mainly from Sweden, a welfare state with high sickness absence rates, our aim was to develop an explanatory theory of how to understand and deal with work absence and sick leave. We used classic grounded theory for analyzing data from >130 interviews with people working or on sick leave, physicians, social security officers, and literature. Several hundreds of typed and handwritten memos were the basis for writing up the theory. In this paper we present a theory of work incentives and how to deal with work absence. We suggest that work disability can be seen as hurt work drivers or people caught in mode traps. Work drivers are specified as work capacities + work incentives, monetary and non-monetary. Also, people can get trapped in certain modes of behavior through changed capacities or incentives, or by inertia. Different modes have different drivers and these can trap the individual from reincentivizing, ie from going back to work or go on working. Hurt drivers and mode traps are recognized by driver assessments done on several different levels. Mode driver calculations are done by the worker. Then follows employer, physician, and social insurance officer assessments. Also, driver assessments are done on the macro level by legislators and other stakeholders. Reincentivizing is done by different repair strategies for hurt work drivers such as body repair, self repair, work-place repair, rehumanizing, controlling sick leave insurance, and strengthening monetary work incentives. Combinations of these driver repair strategies also do release people from mode traps. Reincentivizing is about recognizing hurt work drivers and mode traps followed by repairing and releasing the same drivers and traps. Reincentivizing aims at explaining what is going on when work absence is dealt with and the theory may add to social psychological research on work

    The Atacama Pathfinder Experiment (APEX) project celebrates the inauguration of its outstanding 12-m telescope, located on the 5100m high Chajnantor plateau in the Atacama Desert (Chile). The APEX telescope, designed to work at sub-millimetre wavelengths, in the 0.2 to 1.5 mm range, passed successfully its Science Verification phase in July, and since then is performing regular science observations. This new front-line facility provides access to the "Cold Universe" with unprecedented sensitivity and image quality. After months of careful efforts to set up the telescope to work at the best possible technical level, those involved in the project are looking with satisfaction at the fruit of their labour: APEX is not only fully operational, it has already provided important scientific results. "The superb sensitivity of our detectors together with the excellence of the site allow fantastic observations that would not be possible with any other telescope in the world," said Karl Menten, Director of the group for Millimeter and Sub-Millimeter Astronomy at the Max-Planck-Institute for Radio Astronomy (MPIfR) and Principal Investigator of the APEX project.

The bright peak in the north of the cloud is an evolved star forming region, where the gas is heated by a cluster of new stars. The most interesting region in the image is totally inconspicuous in CO: the G327 hot core, as seen in methanol contours. It is a truly exceptional source, and is one of the richest sources of emission from complex organic molecules in the

  14. FOR MUSEUM WORK

    Full Text Available The role of museums in society has expanded significantly in the last decades: from temples of knowledge to forums for debate and discussion, from repositories of objects to people-centred institutions with social responsibilities and functions. This shift reflects an ongoing trend to democratise museums and make them more accessible to wider audiences and responsive to the public’s changing needs, in particular the interests of local communities, whose composition has changed in recent years to include migrants and people of different ethnic backgrounds. With annual migration flows to the EU as a whole projected to increase from about 1 043 000 people in 2010 to 1 332 500 by 2020, the question of how cultural institutions can contribute to effective integration and dialogue has become more relevant than ever. Funders and society at large expect museums to play their part in facilitating the integration and peaceful coexistence of newcomers, with financial resources being made available, also at the EU level, to support them in this effort. Many questions can be raised as to whether it is right and appropriate to charge museums with these responsibilities and whether this would push the boundaries of their work too far and give the social function an exceedingly prominent role over the traditional conservation and educational tasks museums already fulfil. But this discussion seems to be already obsolete in the light of the growing body of evidence on good practices available at the European level. This essay aims to illustrate some of them, as well as to discuss some underpinning theoretical issues and methodological approaches.

    1994-02-01

    The Work Breakdown Structure (WBS) Book begins with this Overview section, which contains the high-level summary cost estimate, the cost profile, and the global construction schedule. The summary cost estimate shows the total US cost and the cost in terms of PHENIX construction funds for building the PHENIX detector. All costs in the WBS book are shown in FY 1993 dollars. Also shown are the institutional and foreign contributions, the level of pre-operations funding, and the cost of deferred items. Pie charts are presented at PHENIX WBS level 1 and 2 that show this information. The PHENIX construction funds are shown broken down to PHENIX WBS level 3 items per fiscal year, and the resulting profile is compared to the RHIC target profile. An accumulated difference of the two profiles is also shown. The PHENIX global construction schedule is presented at the end of the Overview section. Following the Overview are sections for each subsystem. Each subsystem section begins with a summary cost estimate, cost profile, and critical path. The total level 3 cost is broken down into fixed costs (M ampersand S), engineering costs (EDIA) and labor costs. Costs are further broken down in terms of PHENIX construction funds, institutional and foreign contributions, pre-operations funding, and deferred items. Also shown is the contingency at level 3 and the level 4 breakdown of the total cost. The cost profile in fiscal years is shown at level 3. The subsystem summaries are followed by the full cost estimate and schedule sheets for that subsystem. These detailed sheets are typically carried down to level 7 or 8. The cost estimate shows Total, M ampersand S, EDIA, and Labor breakdowns, as well as contingency, for each WBS entry

  16. How venture capital works.

    Science.gov (United States)

    Zider, B

    1998-01-01

    The popular mythology surrounding the U.S. venture-capital industry derives from a previous era. Venture capitalists who nurtured the computer industry in its infancy were legendary both for their risk taking and for their hands-on operating experience. But today things are different, and separating the myths from the realities is crucial to understanding this important piece of the U.S. economy. Today's venture capitalists are more like conservative bankers than the risk takers of days past. They have carved out a specialized niche in the capital markets, filling a void that other institutions cannot serve. They are the linch-pins in an efficient system for meeting the needs of institutional investors looking for high returns, of entrepreneurs seeking funding, and of investment bankers looking for companies to sell. Venture capitalists must earn a consistently superior return on investments in inherently risky businesses. The myth is that they do so by investing in good ideas and good plans. In reality, they invest in good industries--that is, industries that are more competitively forgiving than the market as a whole. And they structure their deals in a way that minimizes their risk and maximizes their returns. Although many entrepreneurs expect venture capitalists to provide them with sage guidance as well as capital, that expectation is unrealistic. Given a typical portfolio of ten companies and a 2,000-hour work year, a venture capital partner spends on average less than two hours per week on any given company. In addition to analyzing the current venture-capital system, the author offers practical advice to entrepreneurs thinking about venture funding.

With data mainly from Sweden, a welfare state with high sickness absence rates, our aim was to develop an explanatory theory of work and sick leave.We used classic grounded theory for analyzing data from 130 individual interviews of people working or on sick leave, physicians, social security officers, and literature. More than 60,000 words and hundreds of typed and handwritten memos were the basis for the writing up of the theory. In this paper we present a theory of “reincentivizing work”. To understand incentives we define work disability as hurt work drivers or work traps. Work drivers are specified as work capacities + work motivators, monetary and non-monetary. Incentives are recognized when hurt work drivers are assessed and traps identified. Reincentivizing is done by repairing hurt work drivers and releasing from traps. In our theory of reincentivizing work, hurt work drivers and traps are recognized and then repaired and released. The theory may add to social psychological research on work and sickness absence, and possibly inform future changes in sick leave policies.

    Full Text Available Orientation: In order to create competitive advantage in an increasingly turbulent economic environment, sustainability of high performance is crucial. Only a few individuals have the drive, mindset, discipline and ability to sustain high performance on a daily basis. Thus, it is necessary to consider what can be done so that employees can sustain high performance over the long term. Research purpose: The purpose of the study was to establish whether spiritual workplaces will enhance employees’ work engagement and thriving at work. Motivation for the study: Two important mechanisms for understanding the human dimension of sustainability are thriving at work and work engagement. However, because work engagement and thriving are affective-motivational states, it is necessary to consider contextual factors that promote these positive states. As work engagement and thriving at work move beyond mere energy, to a sense of connectedness, it seems important that spiritual workplaces are created. Research approach, design and method: The study was quantitative in nature, and data were collected from employees working at small, medium and macro enterprises (SMMEs in one geographical area in South Africa. The final sample consisted of 259 employees. A survey that was cross-sectional in nature was conducted by means of a self-administered questionnaire. Main findings: The findings of the study show that there is a positive and significant relationship between workplace spirituality, work engagement and thriving at work. Furthermore, workplace spirituality significantly influences the variance in both work engagement and thriving at work. Practical or managerial implications: In order for SMMEs to promote work engagement and thriving at work, spiritual workplaces need to be created. Furthermore, emphasis needs to be placed on the work experience, rather than on work outcomes. It is also important that SMMEs develop employees holistically, that they create

    Full Text Available Clinician Educators (CE have numerous responsibilities in different professional domains, including clinical, education, research, and administration. Many CEs face tensions trying to manage these often competing professional responsibilities and achieve “work-work balance.” Rich discussions of techniques for work-work balance amongst CEs at a medical education conference inspired the authors to gather, analyze, and summarize these techniques to share with others. In this paper we present the CE’s “Four Ps”; these are practice points that support both the aspiring and established CE to help improve their performance and productivity as CEs, and allow them to approach work-work balance.

    Full Text Available Despite repeated attempts to reform schools, teachers' work has remained surprisingly stable. The purpose of this study was to investigate implementation of a state-funded restructuring initiative that intended broad changes in teachers' professional roles. Sponsors of the founding legislation reasoned that changes in teachers' roles would contribute to higher student achievement. This study examined the question of whether and how this program of comprehensive whole-school change promoted changes in teachers' roles in school governance, collegial relations, and the classroom. Further, the study traced the relationship of these changes to one another, and weighed the likelihood that they had the capacity to affect core educational practices. Theoretically, this study is situated in the available literature on teachers' collegial relations; participation in shared decision making; and classroom roles, relationships and practice. Three elementary schools served as the sites for intensive qualitative data collection completed over a two-year period. The schools differed in geographic location (two urban, one rural, but all enrolled a racially, ethnically and linguistically diverse population of students, and more than half of the students in each school qualified for free or reduced price lunch. The study resulted in multiple types and sources of data on teachers' professional roles, including: observations in classrooms, collegial interactions, and governance situations; interviews with teachers (including teacher leaders, parents, administrators, and students; and documents pertaining to the restructuring plans and process. Findings show that changes in the three areas were achieved unevenly in the three schools. All three schools introduced changes in classroom practice and roles, ranging from the adoption of multi-age classrooms to more modest innovations in curriculum or instruction. In only one case were changes in professional roles outside

    To analyze work participation, work productivity, contributing factors, and physical work demands of individuals with upper limb absence (ULA). Cross-sectional study: postal survey (response rate, 45%). Twelve rehabilitation centers and orthopedic workshops. Individuals (n=207) with unilateral transverse upper limb reduction deficiency (RD) or acquired amputation (AA), at or proximal to the carpal level, between the ages of 18 and 65 years, and a convenience sample of control subjects (n=90) matched on age and sex. Not applicable. Employment status, self-reported work productivity measured with the Quality-Quantity method, and self-reported upper extremity work demands measured with the Upper Extremity Work Demands scale. Seventy-four percent of the individuals with RD and 57% of the individuals with AA were employed (vs 82% of the control group and 66% of the general population). Male sex, younger age, a medium or higher level of education, prosthesis use, and good general health were predictors of work participation. Work productivity was similar to that of the control group. Higher work productivity was inversely related to musculoskeletal complaint-related pain. When having predominantly mentally demanding work, individuals with ULA perceived higher upper extremity work demands compared with controls. Work participation of individuals with RD was slightly higher compared with that of the general population, whereas employment rates of individuals with AA were slightly lower. Furthermore, work productivity did not differ between individuals with RD, AA, and controls. Copyright © 2016 American Congress of Rehabilitation Medicine. Published by Elsevier Inc.

    Full Text Available This contribution, which serves as the lead article for the Research Section entitled From Meaning of Working to Meaningful Lives: The Challenges of Expanding Decent Work, explores current challenges in the development and operationalization of decent work. Based on an initiative from the International Labor Organization (ILO; 1999, decent work represents an aspirational statement about the quality of work that should be available to all people who seek to work around the globe. Within recent years, several critiques have been raised about decent work from various disciplines, highlighting concerns about a retreat from the social justice ethos that had initially defined the concept. In addition, other scholars have observed that decent work has not included a focus on the role of meaning and purpose at work. To address these concerns, we propose that a psychological perspective can help to revitalize the decent work agenda by infusing a more specific focus on individual experiences and by reconnecting decent work to its social justice origins. As an illustration of the advantages of a psychological perspective, we explore the rise of precarious work and also connect the decent work agenda to the Psychology-of-Working Framework and Theory (Blustein, 2006; Duffy, Blustein, Diemer, and Autin, in press.

    2008-01-01

    To evaluate work satisfaction among Spanish nurses employed by English hospitals, as well as the influence of several social and work-related variables associated with satisfaction. We performed a cross-sectional study. All Spanish nurses (n=360) with a contract with any English hospital in April 2003 were included in the study. The self-administered and validated Font Roja work satisfaction questionnaire was used. The response rate was 78.6%. Overall work satisfaction among Spanish nurses was medium. The dimensions with higher work satisfaction were relationships with colleagues and superiors. The dimensions showing lowest work satisfaction were job satisfaction and professional competence. Statistically significant and positive associations were obtained between level of English, professional grade, shift pattern, working in the intensive care unit or accident and emergency department, time worked in English hospitals and degree of work satisfaction. Employers of Spanish nurses should try to increase job satisfaction and professional competence among these workers. Incentivation and professional promotion systems might help achieve this aim. Employers could also try to improve Spanish nurses' English level before contracts are signed and pay special attention to their needs during the first working year. Spanish nurses job satisfaction would also increase if they were allowed to choose their working shift and the unit or ward where they are going to work.

    Few studies have investigated the work continuance rate among cancer survivors after return to work (RTW). The objective of this study was to clarify work sustainability after RTW among Japanese male cancer survivors. We collected data on male cancer survivors from an occupational health register. Inclusion criteria were as follows: employees who returned to work after an episode of sick leave due to clinically certified cancer diagnosed between January 1, 2000 and December 31, 2011. Of 1,033 male employees who were diagnosed with cancer, 786 employees (76.1%) returned to work after their first episode of sick leave due to cancer. Work continuance rates among all subjects were 80.1% 1 year after RTW and 48.5% 5 years after RTW. The mean duration of work after RTW was 4.5 years. The work continuance rates varied significantly by cancer type. The "Lung" and "Hepatic, Pancreatic" cancer groups had the shortest duration of work (0.9 year after RTW). Of workers who returned to work after their first episode of leave after cancer, 50% continued to work after 5 years in large-scale companies. There was a steep decrease in work continuance rates during the first year after RTW, with considerable differences according to cancer site.

    Cooks have increased morbidity and mortality. A high turnover has also been reported. We aimed to elucidate work environment and work sustainability in Norwegian cooks. A questionnaire inquiring about working conditions and work participation was sent to 2082 cooks who had qualified from 1988 onwards. Of these, 894 responded. Time at work was analyzed with Kaplan-Meier plots and possible determinants for quitting work as a cook was analyzed with Cox regression. The median time at work was 16.6 years. There were differences in sustainability between types of kitchens for both sexes (p = 0.00). The median time in the profession was 9.2 years for the cooks in restaurants, while the cooks in institutions and canteens showed a substantially higher sustainability with 75.4% still at work after 10 years, and 57% still at work after 20 years in the profession. Of those still at work as a cook, 91.4% reported a good or very good contentment, and the 67.4% who expected to stay in the profession the next 5 years frequently answered that excitement of cooking, the social working environment, and the creative features of cooking were reasons to continue. Musculoskeletal complaints were the most common health-related reason for leaving work as a cook, while working hours was the most common non-health-related reason. There are significant differences in work sustainability between the cooks in the different types of kitchens. The identified determinants for length of time in the occupation can be used for preventive purposes. This work is available in Open Access model and licensed under a CC BY-NC 3.0 PL license.

    Background and aims Research into work addiction has steadily grown over the past decade. However, the literature is far from unified and there has been much debate on many different issues. Aim and methods This paper comprises a narrative review and focuses on 10 myths about work addiction that have permeated the psychological literature and beyond. The 10 myths examined are (a) work addiction is a new behavioral addiction, (b) work addiction is similar to other behavioral addictions, (c) there are only psychosocial consequences of work addiction, (d) work addiction and workaholism are the same thing, (e) work addiction exclusively occurs as a consequence of individual personality factors, (f) work addiction only occurs in adulthood, (g) some types of work addiction are positive, (h) work addiction is a transient behavioral pattern related to situational factors, (i) work addiction is a function of the time spent engaging in work, and (j) work addiction is an example of overpathogizing everyday behavior and it will never be classed as a mental disorder in the DSM. Results Using the empirical literature to date, it is demonstrated that there is evidence to counter each of the 10 myths. Conclusion It appears that the field is far from unified and that there are different theoretical constructs underpinning different strands of research.

    In the current article, we build on research from vocational psychology, multicultural psychology, intersectionality, and the sociology of work to construct an empirically testable Psychology of Working Theory (PWT). Our central aim is to explain the work experiences of all individuals, but particularly people near or in poverty, people who face discrimination and marginalization in their lives, and people facing challenging work-based transitions for which contextual factors are often the primary drivers of the ability to secure decent work. The concept of decent work is defined and positioned as the central variable within the theory. A series of propositions is offered concerning (a) contextual predictors of securing decent work, (b) psychological and economic mediators and moderators of these relations, and (c) outcomes of securing decent work. Recommendations are suggested for researchers seeking to use the theory and practical implications are offered concerning counseling, advocacy, and public policy. (c) 2016 APA, all rights reserved).

    To examine the associations of age, lifestyle and work-related factors, and particularly work engagement with the work ability index (WAI) and its sub-dimensions. Step-wise regression analysis with a sample of Finnish firefighters (n = 403) was used. The outcome variables were the WAI and its six sub-dimensions. The independent variables consisted of age, lifestyle variables (alcohol consumption, BMI, smoking, physical exercise, and sleep problems), working conditions (job demands, physical workload, supervisory relations, and task resources), and work engagement. The outcome variables and all the variables related to lifestyle, working conditions, and work engagement were measured in 2009. Work ability at baseline 10 years earlier was adjusted for in the models. Work engagement, age, physical exercise, sleep problems, and physical workload were associated with the WAI. All independent variables, except BMI and alcohol consumption, were associated with at least one sub-dimension of the WAI after controlling the baseline WAI. Lifestyle variables, working conditions, and work engagement were more strongly related to the subjective WAI sub-dimensions than to the two more objective WAI sub-dimensions. Work engagement was significantly associated with work ability even after adjusting for various factors, indicating its importance in promoting work ability. Other key factors for good work ability were frequent exercise, good sleep, non-smoking, low job demands, low physical workload, and high task resources. More specifically, this study suggests that in maintaining work ability, it is valuable not only to promote lifestyle factors or working conditions, but also to enhance employees' positive state of work engagement.

    Many individuals of working age experience cardiovascular disease and are disabled from work as a result. The majority of research in cardiac work disability has focused on individual biological and psychological factors influencing work disability despite evidence of the importance of social context in work disability. In this article, the focus is on work and organisational features influencing the leeway (margin of manoeuvre) workers are afforded during work reintegration. A qualitative method was used. A large auto manufacturing plant was selected owing to work, organisational, and worker characteristics. Workplace context was assessed through site visits and meetings with stakeholders including occupational health, human resources and union personnel and a review of collective agreement provisions relating to seniority, benefits and accommodation. Worker experience was assessed using a series of in-depth interviews with workers (n = 12) returning to work at the plant following disabling cardiac illness. Data was analysed using qualitative content analysis. Workers demonstrated variable levels of adjustment to the workplace that could be related to production expectations and work design. Policies and practices around electronic rate monitoring, seniority and accommodation, and disability management practices affected the buffer available to workers to adjust to the workplace. Work qualities and organisational resources establish a margin of manoeuver for work reintegration efforts. Practitioners need to inform themselves of the constraints on work accommodation imposed by work organisation and collective agreements. Organisations and labour need to reconsider policies and practices that creates unequal accommodation conditions for disabled workers. Implications for rehabilitation Margin of manoeuvre offers a framework for evaluating and structuring work reintegration programmes.
