    Full text: The nuclear power industry is currently facing increasing aging and obsolescence issues with original equipment installed for instrumentation, control, and safety system applications. One area that needs attention is the aging of electronic boards and components used in instrumentation and control (I and C) systems in nuclear power plants (NPPs). In this context, EPRI has launched a project dedicated to NPP electronic component and board aging management. The goals of this project are: 1) to better understand the degradation mechanisms of I and C electronic systems; 2) to develop new methods to monitor prevalent mechanisms and forecast generic aging cases; and 3) to give guidelines for the aging management of I and C electronic systems. The ultimate objectives are: 1) to reduce the likelihood of losing plant availability due to a board or component failure; and 2) to reduce the global cost of maintenance by optimizing preventive maintenance tasks and the schedule for refurbishment or renewal. Degradation mechanisms of electronic boards in NPP - Aging mechanisms of electronic parts depend on technologies, manufacturing quality, and conditions of environment and operation. Aging of electronic parts is well documented in harsh environments (e.g., aerospace, military, or automotive industries data). However, only a small amount of data on electronic part failures in NPPs is available because the conditions are benign and the failure rates are supposed to be low. It is thus difficult to identify what will predominantly cause the aging of electronic systems after 20 or 30 years of operation. Usual causes are temperature, corrosion, temperature cycles, or extrinsic aggressions (Electrical Over Stress (EOS), Electro Static Discharges (ESD)). From field data and bibliographic analyses, we found that electrolytic capacitors, relays, potentiometers, power devices (thyristors, power transistors, etc.), optocouplers, on-board connectors, printed boards, integrated

    Ageing management programme in a plant calls for the estimation of remaining life of the component. Reliability analysis methods using remaining life estimation models have found profound application in providing directives in ageing management programme. As a part of ageing management programme of H 2 S based heavy water plants, the remaining life estimation models are applied to the pipelines carrying H 2 S. The pipelines under H 2 S environment are more susceptible to the internal corrosion thereby reducing the pipeline's load carrying capacity. The objective of this study is to obtain the remaining life of pipelines under ageing due to internal corrosion. The ageing assessment of pipelines involves estimating the failure pressure of a pipeline and evaluating the failure surface equation. Several failure pressure models developed for assessing the pipeline's remaining strength due to internal corrosion were studied for this purpose. From the study, it was found that the modified B31G failure pressure model is most suitable for modeling the pipeline failure pressure. Due to the presence of non-linearity in the failure surface equation or limit state function and non-normal variables, the first order second moment method has been employed for carrying out the reliability analysis. The uncertainties of the random variables on which the limit state function depends are modeled using the probability distributions. The failure probabilities of the pipelines have been evaluated for the service lives of 15 and 25 years, which are the present life and designed life respectively. In addition, sensitivity analysis was carried out to identify the most important sensitive parameters in reliability analysis estimation. The paper highlights the application of these methodologies in the context of pipeline remaining life estimation with a suitable case study. (author)

    An aging society is one of the most important demographic, social and economic challenges facing the contemporary world. Human capacity to perform work changes with age, which is mostly caused by the decrease in physical capacity, physical fitness and in some elements of psychophysical fitness (e.g., perceptibility, reaction time, efficiency of sense organs). Moreover, the incidence of disorders of the circulatory, respiratory, and musculoskeletal systems as well as of hormonal and metabolism disorders is higher in older persons. On the other hand, the requirements posed by professional work, as long as no change of post takes place, most often remain the same irrespective of age. As a result, the actual workload may increase with age. Although work ability decreases with age, the demographic and economic contexts point to the necessity to prolong occupational activity. It is justifiable to encourage an increasing number of elderly workers to remain in employment but only if the measures are being taken to maintain their work ability during the entire occupational activity period and to advance their qualifications. These measures must be accompanied by activities targeted at the modification of tasks, work stands, time and rhythm of work, so as to adapt them to the changing worker's capacities. Numerous activities are being systematically implemented in enterprises and the process is called "age management". The article describes the main assumptions of this new approach and the role of occupational physicians in the whole process.

    As of December 1994, 34 PWR 900 MW units and 20 PWR 1300 MW units are in operation, giving a total of more than 57,000 MW installed. These units are standardized and provide 75 percent of the French electrical output. They were all brought into service within a 15 year period. Considering the situation of those units in the production capacity, it is hardly necessary to point out the importance of a correct assessment of their potential lifetime (plant life management).

    The Controlled Parts Management (CPM) system is based on industry standard practices for managing inventory. CPM is designed to record the movement of any type of inventory in a defined region referred to as an Account or SubAccount. The system is used to track the receiving, processing, storing and transfer of inventory parts. CPM provides information on parts, quantity and the exact location of the inventory. CPM is a barcode-based-part tracking system currently used to track controlled parts that are used in the R and D and testing of weapons; this tracking helps maintain the part pedigree that is required for certification of a weapon or weapon test. CPM includes bar code data collection software programmed into portable bar code readers for automating physical inventory services and remote transaction capture. CPM interfaces to other Engineering systems and supports a 'material content' of a weapons test through the test Bill of Materials and assignment of a unique inventory part in CPM. Additional functionality includes the ability to group or join parts, logically or physically and temporary or permanent, to represent discrete parts, containers, subassemblies and assemblies, and groupings.

    Fink-Samnick, Ellen

    PRIMARY PRACTICE SETTING(S):: Applicable to all health care sections where case management is practiced. This article is the third of a 4-part series on the topic of bullying in the health care workplace. Part 3 addresses the dimensions of the bullying boss and leadership, posing major implications for patient safety plus the mental health of staff members. The complex constructs and dynamics broached by the bullying boss and department leadership are explored. These include the underlying forces at play such as power, gender, leadership styles, plus weaves in assessment models. Strategic and proactive management of bullying by leadership is vital to workforce retention and well-being. The increasing incidence and impact of bullying across all sectors have made it a major workforce performance management challenge. Health care settings are especially tense environments, often making it difficult for individuals to distinguish between bullying behavior and high expectations for staff. Bullying impacts both direct targets and bystanders who witness the assaultive behaviors, with ethical implications as well.Case management is poised to promote a safe health care workplace for patients and practitioners alike amid these intricate circumstances. Understanding types of bullying bosses and leadership styles is integral to a case manager's success in the workplace.

    As a part of Periodic Safety Review Program (PSR) NEK will review and perform some activities related to Equipment Qualification (EQ) and Aging Management Program (AMP). (EQ) and AMP are safety factors, which need to be assessed during PSR. The goal of PSR and AMP is to determine aging effects and give the conclusion whether the plant has been managed to control aging related degradations and that safety margins are maintained. The parallel goal is also to establish AMP for future plant operation and provide basis for possible Life Extension Program. NEK will develop NEK Aging and Life Cycle Management Program, similar by format and content to one determined by License Renewal program. The bases are in 10CFR54, and NEI 95-10 Industry Guidelines for 10 CFR 54 implementation. The process of establishment the AMP is to be done in two steps. The first step is dealing with SSC's (Systems Structures and Components) scoping and screening and identification of TLAA's (Time Limited Aging Analyses). That means, that a database of all SSC's and TLAA's will be created and then evaluated within AMP program. Based on the scope in first phase an evaluation will be performed in step two. NEK will maintain AMP program as a living program that may be also used for Life Extension and Life Cycle Management. This paper will present and describe AMP, scoping and screening process and the results achieved through the first phase of the project.(author)

    The aspects of plant ageing management (AM) gained increasing attention over the last ten years. Numerous technical studies have been performed to study the impact of ageing mechanisms on the safe and reliable operation of nuclear power plants. National research activities have been initiated or are in progress to provide the technical basis for decision making processes. The long-term operation of nuclear power plants is influenced by economic considerations, the socio-economic environment including public acceptance, developments in research and the regulatory framework, the availability of technical infrastructure to maintain and service the systems, structures and components as well as qualified personnel. Besides national activities there are a number of international activities in particular under the umbrella of the IAEA, the OECD and the EU.

    Since the adoption of the 1997 act of parliament concerning the abolishment of nuclear power in Sweden plant lives are no longer limited until 2010 as they were following the referendum in 1980. The Swedish Nuclear Power Inspectorate (SKI) has therefore in its most recent general regulations from 2004 introduced requirements for plants to develop ageing management programmes which should have been in place by the end of 2005. An ageing management programme for a nuclear power plant can be viewed as a high level coordinated programme consisting of several other programmes including maintenance and inspection programmes, and as such it should be an integrated part of the quality assurance system of the plant. The goals of the programme are to ensure that there is long term management of ageing and avoidance of the unexpected. For the Swedish regulator the safety aspects and not the economic aspects of ageing management are of primary importance. But there are clear advantages to utilities if large surprises which result in unplanned outages can be avoided. (author)

    As operation time is accumulated, the overall safety and performance of NPP tend to decrease. The reasons for potential non-availability of the structures, Systems and Components (SCC) in operation, are various but they represent in different mode the end result of the ageing phenomena. In order to understand the ageing phenomena and to be able to take adequate countermeasures, it is necessary to accumulate a big amount of information, from worldwide and also from the own plant. These Data have to be organized in a systematic form, easy to retrieval and use. General requirements and structure of an Ageing DataBase Activities related to ageing evaluation have to allow: - Identification and evaluation of degradation phenomena, potential malfunction and failure mode of the plant typical components; - Trend analyses (on selected critical components), prediction of the future performance and the remaining service life. To perform these activities, it is necessary to have information on similar components behavior in different NPP (in different environment and different operating conditions) and also the results from different pilot studies. The knowledge of worldwide experience is worthwhile. Also, it is necessary to know very well the operating and environmental conditions in own NPP and to analyze in detail the failure mode and root cause for the components removed from the plant due to extended degradation. Based on the above aspects, one presents a proposal for the structure of an Ageing DataBase. It has three main sections: - Section A: General knowledge about ageing phenomena. It contain all the information collected based on the worldwide experience. It could have, a general part with crude information and a synthetic one, structured on typical components (if possible on different manufacturers). The synthetic part, has to consider different ageing aspects and different monitoring and evaluation methods (e. g. component, function, environment condition, specific

    Worldwide, due to the age of the majority of nuclear generating stations significant attention is being paid to the condition of the major components, e.g., reactor, steam generator, turbine generator, transformer, etc., with respect to relicensing and life extension. However, there is recognition that cable systems are critical to the safe, reliable and economic operation of nuclear power plants. Consequently, there is great interest in ageing management of low and medium voltage cables in the nuclear environment. Successful implementation of such programs requires an understanding of how the materials associated with cables and their accessories behave under normal operating and accident conditions. However, there is also a great need to determine the actual condition of the materials and systems in order to make rational decisions on whether or not to replace cables to ensure long term assurance of reliable operation. This proposed contribution describes an approach to cable ageing management of low and medium voltage cables based on measurements of material and electrical properties obtained in the laboratory and in the field. The effectiveness of various chemical, mechanical and electrical test methods are discussed in the context of, • Cable configuration, i.e., low or medium voltage, shielded or unshielded • Material type, i.e., PVC, XLPE, EPR, etc., • Ageing stress, i.e., electrical, thermal, radiation, thermal plus radiation, etc. These factors are key to identifying the most appropriate test method (or methods) to enable understanding of the current condition of the cable. While electrical test methods, e.g., ac withstand testing, partial discharge and various dielectric loss measurement techniques have been found effective for medium voltage cables, they are of very limited use on low voltage cables that constitute the majority of cables in nuclear power plants. This limited effectiveness is due to the lack of a well defined ground plane that is a

    Approximately 20% of the present electric generating capacity in the United States is supplied by nuclear power plants and may be retired due to initial license expiration between the years 2002 and 2030. One of the recommended actions for implementing the National Energy Strategy (Bill H.R. 776) is license renewal of currently operating nuclear power plants which DOE has estimated would save between $800 million and $1 billion in avoided new construction costs - and represent a nationwide benefit of as much as $350 billion - assuming the licenses are renewed for 20 years. The U.S. Atomic Energy Act of 1954 limits the duration of operating licenses of nuclear power plants to a maximum of 40 years but permits their renewal. And, although Title 10, Part 50.51 of Code of Federal Regulations (10CFR50.51) permitted license renewal, it provided no standards or procedures for renewal applications. License renewal requirements were established on January 13, 1992 when NRC's Final Rule (10 CFR Part 54) went into effect. The Final rule established the requirements that an applicant for license renewal must meet, the information that must be submitted to the NRC for review. This involves the performance of an Integrated Plant Assessment (IPA) which is designed to ensure that the effects of aging on important equipment will be adequately managed during the renewal term. The issuance of 10 CFR Part 54 established the regulatory and legal requirements for license renewal. The technical basis for, or viability of, license renewal has been explored by the Electric Power Research Institute (EPRI) since the late 1970s/early 1980s. The NRC as well as industry organizations such as EPRI have studied aging effects for close to two decades. The NRC's research program on plant aging degradation, which began formally in the early 1980s, is a comprehensive effort for the understanding and management of age-related degradation in safety-related systems, structures, and components (SSCs) and

    Systematic and effective control of age-related degradation of safety-related components, systems, and structures in nuclear power plants (NPPs) is an important challenge to plant operators. Several data bases, available to provide guidance on aging management, are summarized. However, the ultimate consideration is: How effectively is aging management being implemented at individual plants? Illustrated here is a specific strategy that served to develop the technical data base for the Nuclear Plant Aging Research Program. The strategy is comprehensive, systematic, and adaptable. Effective aging management at NPPs could be facilitated by a parallel strategy. The elements of a strategy are suggested

    Cirus, a 40 MWt tank type research reactor located at the Bhabha Atomic Research Centre, is in operation since 1960. In Cirus, heavy water is used as moderator, demineralized light water as primary coolant and natural uranium metal as fuel. The average availability factor had been about 70% till the year 1990 where after it started decreasing due to frequent problems with equipment and components. Systematic aging studies were therefore undertaken to assess the condition of structures, systems and components. Based on these studies, refurbishing requirements were identified and a detailed plan was drawn up for refurbishing. The reactor was shut down in October 1997 for execution of refurbishing jobs. A summary is presented of the results of aging studies and the refurbishing plans. Details of core unloading to facilitate refurbishing and some of the important jobs in the primary coolant system relating to pressure testing of primary coolant pipelines and repairs to identified leaky sections are discussed.

    In February 2013, there are 50 units of commercial nuclear power plants (NPPs) in Japan. We enter into a period that 20 units of them are operating for more than 30 years. Currently, regulation imposes utilities to conduct ageing technical evaluations of each unit before operation of 30 years from the commissioning, to develop the long term maintenance management policy for next 10 years and to submit to the regulatory authority the policy with the report on ageing management technical evaluation (AMTE) for each NPP. It is necessary for regulatory side to develop technical information bases incorporating latest technical knowledge as operating experiences in domestic and abroad on ageing of the plants necessary to conduct reviews of AMTE for each unit. Based on these standpoints, technical information bases investigations have been conducted from the viewpoints of material degradation of ageing NPPs. In order to develop scientific regulator judgment bases related to ageing management (AM) and long-term operation (LTO), investigations on latest information on ageing management in domestic and abroad are conducted and a set of documents including technical evaluation review manuals necessary to conduct AMTE are prepared. To utilize the results of the investigations for ageing technical evaluation, database including latest information related to AM and LTO are developed, ran and operated. In addition, investigations related to Fugen nuclear plant, under decommissioning plants, investigations on mechanism of stress corrosion cracking (SCC), thermal ageing and preventive technologies for SCC, detection and diagnosis technology for ageing degradation and condition monitoring technology are performed to validate and confirm effectiveness of the technologies.

    As of December 1993, about one quarter of the operating research reactors were over 30 years old. The long life of research reactors has raised some concern amongst research reactor operators, regulators and, to some extent, the general public. The International Atomic Energy Agency commenced activities on the topic of research reactor ageing by appointing an internal working group in 1988 and convening a Consultants Meeting in 1989. The subject was also discussed at an international symposium and a regional seminar held in 1989 and 1992 respectively. A draft document incorporating information and experience exchanged at the above meetings was reviewed by a Technical Committee Meeting held in Vienna in 1992. The present TECDOC is the outcome of this meeting and contains recommendations, guidelines and information on the management of research reactor ageing, which should be used in conjunction with related publications of the IAEA Research Reactor Safety Programme, which are referenced throughout the text. This TECDOC will be of interest to operators and regulators involved with the safe operation of any type of research reactor to (a) understand the behaviour and influence of ageing mechanisms on the reactor structures, systems and components; (b) detect and assess the effect of ageing; (c) establish preventive and corrective measures to mitigate these effects; and (d) make decisions aimed at the safe and continued operation of a research reactor. 32 refs, tabs

  7. Plant maintenance and aging management: Are they the same?

    As part of the NRC's Nuclear Plant Aging Research Program, a number of aging studies were performed on safety-related systems and components which found that, even with current maintenance and monitoring practices in place, a large number of the reported failures are related to aging. This suggests that current practices are not sufficient to completely manage aging degradation, and other factors need to be considered. This paper examines the aging management process and the degree to which maintenance plays a part in it. Component failures and degradation mechanisms identified in aging studies of several different safety systems are summarized and evaluated, then con-elated with the components most frequently failed. This information, along with an analysis of failure causes, is then used to determine the extent to which aging is managed by current maintenance practices. Conclusions and recommendations for proper aging management arc also presented

The task the management has to take to secure competitiveness in an environment of rising complexity of production processes and further increasing legal requirements, is to manage waste as much as other recourses are managed. Waste has to be considered an aspect of planning and decision process just as business plans or logistics are. Main themes discussed in this publication comprise waste management, implementation of waste management as an integral part of environmental management systems, and management approach to waste - the results. 4 figs.

    The containment system in a Nuclear Power Plant (NPP) provides the final physical barrier against release of radioactive materials to the external environment. Even though there are different physical configurations to meet this fundamental safety function in various reactor types, a common feature is the use of a thick-walled concrete structure as part of the containment system commonly referred to as 'Concrete Containment Building'. In order for the concrete containment buildings to continue to provide the required safety function, it has to maintain its structural integrity. As well, its leak rates under test pressures must be maintained below acceptable limits. As some of the containment buildings of the CANDU nuclear power plants are approaching their fourth decade of successful operation, questions regarding the impact of ageing on their ultimate useful service life emerge. Ageing Management has become the tool for addressing those questions. In this paper, the ageing and ageing management of the CANDU concrete containments are discussed, including the specific programs being implemented to monitor and trend the ageing conditions. Specifically, the usefulness of the embedded strain gauges as a tool for the assessment of the condition of the containment concrete structure is discussed. Some of the operational and test data accumulated over the last 30 years have been evaluated and trended to provide some results and conclusions regarding the satisfactory long-term behaviour of the concrete containment buildings.

    During operation of nuclear power plants, the quality of systems, structures and components may change as a result of ageing (conceptional ageing, technological ageing or physical ageing), which will affect the system quality. Ageing management is necessary to ensure safety and availability throughout the life of the systems. This necessitates a systematic, integrative and knowledge-based approach. Systems, structures and components are grouped according to their relevance for meeting the set goals. Ageing mangement should be process-oriented and should be integrated in the organisational procedure in cooperation with the safety manager. The procedure should follow the PDCA principle (plan - do - check - act). The data, documents, knowledge and evaluations required for ageing management are part of the knowledge base of the nuclear power station and are updated regularly. The efficiency of ageing management must be reassessed at regular intervals. (orig.)

    Aging management is part of the safety management system in NPP Neckarwestheim, Germany. The central goal of aging management is to increase knowledge about aging mechanisms acting on systems, structures and components (SSC), steadily. Comprehensive knowledge is a pre-requisite to guard against aging related systematic failures. To increase knowledge it is necessary to gather and evaluate data of different departments, systematically. While a nuclear power plant is in service numerous events may occur which are related to aging and may have an influence on the quality of SSC. Relevant events may be malfunction, maintenance results, operational experience, results of surveillance or events in other utilities. It is important to evaluate these events concerning the aspect of aging, regularly, and to decide which measures are required to prevent similar unexpected events in the future. In some cases the new experience has to be assigned to comparable SSC. These evaluations and the necessary measures as well as the tracking of their effectiveness are performed by an aging management team that meets every 3 months. The resulting knowledge data base (aging management data base) supports the application of the PDCA cycle and provides an overview and fast access to all quality documents related to each SSC including surveillance measures and results. It simplifies the generation of annual status reports which demonstrate the efficiency of aging management. Finally, the procedure can be extended to SSC which are important for the availability of the plant and thus take a step forward from aging management to plant life management.

  13. Aging management review for license renewal and plant life management

    Full text: United States nuclear power plants are initially licensed for a period of 40-years. The 40-year term, which was established by the Atomic Energy Commission in the 1950s, is believed to be based on engineering judgement and is consistent with the typical amortization schedule for purchasing fossil power plants. Under 10 CFR Part 54, the license renewal rule, additional terms of 20-years may be obtained through the preparation of a license renewal application that must be reviewed and approved by the Nuclear Regulatory Commission (NRC). The license renewal rule requires that applicants perform ageing management reviews on passive long-lived structures and components to demonstrate that ageing will be managed during the period of extended operation (i.e., additional 20 years of operation). ageing of active components, which are excluded from 10 CFR Part 54, is accomplished through the Maintenance Rule, 10 CFR Part 65, using performance-based monitoring. The license renewal rule, 10 CFR Part 54, was initially published in 1991. After significant interaction with the nuclear industry from 1991 through 1994, the NRC revised the rule in 1995 to focus on passive long-lived structures and components. In 1998, the first two applications for license renewal were submitted to the NRC by Baltimore Gas and Electric for the two-unit Calvert Cliffs nuclear power plant and by Duke Energy for the three-unit Oconee nuclear power plant. In March 2000, the NRC approved the application for the two-unit Calvert Cliffs nuclear power plant for an additional 20 years. Two months later, the NRC approved the renewal of the operating licenses for the three-unit Oconee nuclear station. The NRC completed these reviews in a timely, predictable, and stable manner. As of February 2002, the NRC has approved renewal of operating licenses for eight nuclear units and has applications under review for 15 more units. Twelve additional companies have notified the NRC of their intention to seek

    questionnaire for the systems to emphasize interfaces separation and repair possibilities during plant operation; Components screening, was realized evaluating at every system the effect of its component failure (local, at the system level, at the plant level). 3. Critical representative components As result of the screening resulted a lot of components to be monitored from ageing point of view. But some are redundant components or are similar and work in the same conditions. For this reason where chosen critical representative components. The conclusions on these representative components shall be applied also to the rest of the critical components. 4. Correlation with maintenance categories. As result of the components screening results: Critical components (from the safety and reliability point of view); for these components shall be applied Condition Oriented Preventive Maintenance; Non critical components; for these components shall be applied Corrective Maintenance (they are Run to Failure Components); If during plant operation result that for some critical components it is enough to realize maintenance based on the manufacturer instruction, shall be applied for them Time Oriented Preventive Maintenance (instead of Condition Oriented Preventive Maintenance). Of course this is the first selection. After some times of application at Cernavoda NPP of an ageing Management Program it shall be revised according to the results in operation. (author)

    1992-01-01

    For a variety of economic and technical reasons, there has been a growing concern with the aging of complex systems and components and the role that maintenance can play in reducing this degradation. A study for the Nuclear Regulatory Commission was recently undertaken to identify effective maintenance practices that could be adapted by the nuclear industry in the United States to assist in managing the aging degradation of plant systems and components. Four organizations were examined to assess the influence that their maintenance programs have on their ability to address the systems and component aging degradation issues. An effective maintenance program was found to be essential to the management of system and component aging. The four key elements of an effective maintenance program that are important to an aging management program were identified. These are: the selection of critical systems and components; the development of an understanding of aging through the collection and analysis of equipment performance information; the development of appropriate preventive and predictive maintenance tasks to manage equipment and system aging degradation; the use of feedback mechanisms to continuously improve the management of aging systems and components. These elements were found to be common to all four organizations. In examining how the four organizations have structured their maintenance programs to include these key elements provides valuable lessons not only for the nuclear power industry, but also for any industrial organization that is concerned with the management of system and component aging degradation. This document provides detail, of these studies

    Full Text Available Part 1 of this guideline addressed the differential diagnosis of the neurofibromatoses (NF: neurofibromatosis type 1 (NF1, neurofibromatosis type 2 (NF2 and schwannomatosis (SCH. NF shares some features such as the genetic origin of the neural tumors and cutaneous manifestations, and affects nearly 80 thousand Brazilians. Increasing scientific knowledge on NF has allowed better clinical management and reduced rate of complications and morbidity, resulting in higher quality of life for NF patients. Most medical doctors are able to perform NF diagnosis, but the wide range of clinical manifestations and the inability to predict the onset or severity of new features, consequences, or complications make NF management a real clinical challenge, requiring the support of different specialists for proper treatment and genetic counseling, especially in NF2 and SCH. The present text suggests guidelines for the clinical management of NF, with emphasis on NF1.

    One of the requirements for nuclear plant license renewal may be the establishment and demonstration of an effective aging management program. An analysis of both qualitative and quantitative information will be required to define the contents of this aging management program. The authors propose two quantitative figures of merit, Mean Event Detection Frequency and Mean Renewal Rate, that can be used to compare the effectiveness of various inspection, surveillance, test, and monitoring (ISTM) activities for aging mitigation. An example showing the relative effectiveness of an enhanced Loose Parts Monitoring System with current ISTM activities for steam generators and reactor internals is provided. (author)

    The knowledge of how the environment and load of organic material in general and especially polymers and lubricants, is affecting the degradation of important properties, have increased during the last decade. However the restrictions using established additives like some color pigments due to their poisonousness e.g. pigments based at cadmium, lead, mercury etc. have caused problems when replacing additives to polymers. The replacement additives have often been used in new design without going through the required material qualification procedure. There have also been observed that some non-qualified and non-approved materials have been installed in some power plants due to false documentation. There are also a lot of new manufacturers, of materials similar to the previously qualified materials, active at the market. This increases the difficulty to ensure that the required material quality is used. New materials, new additives and new manufacturers makes if more and more difficult to assure that the expected material is present. This causes more strict demands of how the new materials often used in equipment at type-testing and in replacement materials are analyzed and documented. By implementing new steps for chemical, mechanical and electrical analysis and increase the general quality assurance content this issue can be managed. (authors)

    Ageing management has now become a vital area of concern. Ageing management includes determination of degradation factors, taking various steps to determine present conditions of systems, structures and components and taking mitigating steps. It also includes updating, modernization, refurbishment etc. It is important that ageing management starts right from the time of commissioning of the unit and is treated as a continuous process, and a parallel effort to the normal running of the plant. Thus elaborate research and development efforts are required to be instituted. Life extension could have a high benefit to cost ratio. Various steps to ensure safety in ageing management are listed. Selection of critical items, condition monitoring and life estimation of the same and a chronological check sheet from 0 to 60 years, for Indian PHWRs is explained. Areas where future research and development and other efforts need to be directed is listed. The paper concludes emphasizing the need for a systematized approach to ageing management. It recommends intensive research in certain listed areas and suggests standing committees in specialized areas to tap Indian experience in other industries and establishments. A safety guide is also required to be produced to cover all facets of ageing management. (author). 3 appendices

    Unit-l of Rajasthan Atomic Power Station (RAPS-1) is the first nuclear power plant of India with pressurized heavy water reactor. The construction of Unit-l of Rajasthan Atomic Power Station (RAPS-1) was started in the year 1966 in collaboration with Canada. The Unit-1 achieved first criticality on August 1972 and was first synchronized to Grid on November 1972. During initial operation of the Unit, several problems were faced in its various systems and these were addressed by incorporating various engineering changes and procedures. In this unit various major innovative repairs were done like end shield leak repair, OPRD leak repair. Considering the operation of various systems of Unit-1, since year 1971 it was imperative to study ageing degradation mechanisms and mitigating measures were to be taken. Although the ageing management is a continuous process the opportunity of Unit-1 shutdown for upgradations from 30-04-2002 to 08-02-2004 was utilized for inspection and assessment of health of various SSC, which otherwise could not have been done with unit in operational state. This paper contains the following in detail. (1) Ageing management programme, its objectives and scope (2) Methodology of ageing management studies - Replacement and upgradation -Additional inspection programme based on ageing management review - Statistical analysis of ageing degradation occurrence - Estimation of residual life span of cables and relays (3) Criteria for selection of components for ageing management programme (4) Findings of ageing management studies-case studies. The ageing study done for RAPS-1 indicated that appropriate ageing monitoring methods and procedures exist in the station for taking timely mitigating measures. The technological obsoleteness has been overcome by installing new components of latest technology. On overall assessment, the Unit-1 was considered fit for further service. (author)

    It is a generally accepted fact that while designing a concrete structure the durability parameters of construction materials should be evaluated as carefully as possible like other properties such as mechanical, physical and chemical properties. No material is inherently durable as result of environmental interaction with microstructure and consequently, the properties of the materials change with time due to weathering action, chemical attack, abrasion or any mode of degradation. The main cause of ageing on structure, water, which is primary for both creation and destruction on many natural materials. In porous materials, water creates different types of physical and chemical process of degradation. The water movement through porous materials are controlled by the permeability of the respective materials. The rate of deterioration is affected by type of concentration of ions present in the water and chemical deposition of materials. Controlling weathering action, chemical attack, abrasion and selecting good quality construction material and methods of construction can increase the service life of the structure. (author)

    The incidence and prevalence of chronic renal disease (CKD) in elderly patients are continuously increasing worldwide. Loss of renal function is not only considered to be part of the aging process itself but also reflects the multimorbidity of many geriatric patients. Calculating the glomerular filtration rate using specific algorithms validated for the elderly population and measuring the amount of proteinuria allow an estimation of renal function in elderly patients with high accuracy. Chronic renal failure has many clinical consequences and not only results in a delayed excretion of toxins cleared by the kidneys but also affects hematogenesis, water and electrolyte balance as well as mineral bone metabolism. Furthermore, CKD directly leads to and aggravates geriatric syndromes and in particular the onset of frailty. Therapeutic strategies to halt progression of CKD not only comprise treatment of the underlying disease but also efficient blood pressure and diabetic control and the avoidance of nephrotoxic medications.

    In Germany, the term 'ageing management' comprises several aspects. A demand for a special ageing monitoring programme is not explicitly contained in the regulations. However, from the Atomic Energy Act and its regulations results the operator's obligation to perform extensive measures to maintain the quality of the plant and the operating personnel working in the plant. From this point of view, comprehensive ageing management in German nuclear power plants has taken place right from the start under the generic term of quality assurance. (author)

    The recently issued International Atomic Energy Agency (IAEA) publications (GS-R-3, GS-G-3.1 and GS-G-3.5) regarding Management Systems for Facilities and Activities define requirements for creation, introduction, evaluation and continuously improvement of the Management System, which unifies the safety, health, environment, security, quality and economic elements. According to GS-R-3 the Integrated Management System is based on defined processes identified in the enterprises: Managing, Basic and Supporting processes. At implementation of their activities, the organizations often apply other standards in their interrelations with suppliers and the parties concerned - ISO 9001:2008, ISO 14001:2004 and OHSAS 18001:2007, regarding quality, environment and occupational health and safety management. The integration of the standards of both series ensure the observance of the common management principles that reflect the best practices of management as leadership, participation of the people, process approach, continuously improvement, systematical approach to the management and approach based on facts used at the making decisions. The main objective of the Integrated Management System introduction is to ensure safety considering the influence of all additional impacts taken together. The Integrated Management System is based on the process approach at implementation of the activities in nuclear power plant. The transition to the process oriented approach require long period of time, during which the distribution of the responsibilities is optimized up to the level that will satisfy the requirements, reach and maintain the stipulated objectives. The Configuration Management (CM) is an integrated management process by means of which conformity between design requirements, physical configuration and the plant documentation is ascertained and maintained during the entire life cycle of the facility. Processes within configuration management are not isolated, but are part of

    To assist in the long-term health management of residents and evaluate health impacts after the Tokyo Electric Power Company's Fukushima Daiichi Nuclear Power Plant accident in Fukushima Prefecture, the Fukushima prefectural government decided to conduct the Fukushima Health Management Survey. This report describes the results for residents aged 16 years or older who received the health check examinations and evaluates the data obtained from 2011 and 2012. The target group consisted of residents aged 16 years or older who had lived in the evacuation zone. The health check examinations were performed on receipt of an application for a health check examination from any of the residents. The examinations, including measurements of height, weight, abdominal circumference/body mass index (BMI), blood pressure, biochemical laboratory findings, and peripheral blood findings, were performed as required. 1) A total of 56,399 (30.9%) and 47,009 (25.4%) residents aged 16 years or older received health checks in 2011 and 2012, respectively. 2) In both years, a number of male and female residents in the 16-39 year age group were found to suffer obesity, hyperlipidemia, hyperuricemia, or liver dysfunction, and the prevalence of obesity and hyperlipidemia among residents increased with age. Furthermore, the proportion of residents with hypertension, glucose metabolic abnormalities or renal dysfunction was higher in those aged 40 years or older. 3) The frequencies of obesity, hypertension and hyperlipidemia among residents in 2012 were lower than those in 2011. However, the prevalence of liver dysfunction, hyperuricemia, glucose metabolic abnormalities and renal dysfunction among residents was higher in 2012 than in 2011. These results suggested the number of residents who had lived in the evacuation zone with obesity, hyperlipidemia, hyperuricemia, liver dysfunction, hypertension, glucose metabolic abnormalities, or renal dysfunction increased with age in all age groups

  14. Elastodynamic spot testing - assessing serviceability of aging elastomer parts

    The properties of all polymers change with time as a function of their environment. Traditional practice has been to replace these parts according to generic time limits based on estimates of worst case material properties and conditions. This is overly-conservative in many cases, and creates unnecessary maintenance work and costs for replacement and disposal. Much of this could be avoided if the serviceability of elastomeric parts such as seals, diaphragms, gaskets, cable insulation and hoses could be reassessed on a routine basis. Elastodynamic spot testing offers a way to do this. Parts can be sampled while in service or storage to compare their as-new and used (or aged) elastodynamic properties. This data can usually be correlated with the results of functional tests to prove that material properties have not degraded to the point where the part could fail. This spot testing is similar to a micro-hardness test, but includes stress-relaxation and subsequent recovery. It provides a nondestructive means to assess the effective age of the material at a point, or several points, on a part. Sampling of hardness alone is rarely sufficient to know whether a part is still functional because this overlooks the material's viscoelastic and strength properties. An elastodynamic spot tester has been used to test different sizes, shapes and hardnesses of elastomeric parts at different levels of strain, i.e., indentation depths. An initial test program has given informative relaxation and recovery data, showing repeatability and comparing well with finite element analysis of the indentation process. Tests of aged 0-rings and diaphragms have revealed different elastodynamic properties, depending on the elastomer compound and aging conditions. (author)

  15. Operational and materials aspects of aging management

    Understanding degradation phenomena and managing the detrimental effects of aging are important aspects of commercial nuclear power plant operations. Potential for materials degradation should be considered early in the design and development stages; during manufacturing, construction, and installation; and during all aspects of plant operation and maintenance. This would lead to increased reliability during plant operations, and would reduce the need for mitigating actions and unplanned maintenance. Thus, it is necessary to instill a culture at the technical, administrative, and management levels that continually asks, 'What happens with time?' The answer to this question is central to the continuous safe and economical operation of nuclear power plants. Based on the past 25 years of aging-related research at the U.S. Nuclear Regulatory Commission (NRC), the authors present an overview of the key elements of understanding and managing aging, and how they should be integrated for safe and economical power plant operation. The focus of this paper is hardware-oriented engineering and aging of materials. The paper discusses previous and ongoing NRC research studies on non-destructive examination and materials degradation that can be applied for proactive management of materials degradation and aging during plant operations.

    Materials ageing is a time-dependent process, that involves the loss of availability of nuclear plants. Radiation embrittlement, stress corrosion cracking, irradiation assisted stress corrosion cracking, and thermal ageing are the most relevant time-dependent material degradation mechanisms that can be identified in the materials ageing process. The Materials Programme of Nuclear Energy Institute at CIEMAT carries out research projects and metallurgical examinations of failed components to gain some insight into the mechanisms of materials degradation with a direct impact on the life management of nuclear plants.

    2004-01-01

    Bechtel is currently completing an aging study on a concrete containment structure. The target plant is a two-unit PWR plant with a generating capacity of about 850 MWe from each unit. Both units are less than 20 years old. The total electrical energy output from this plant site accounts for more than 50% of the utility's baseload operation. Although no utility in the United States has made a decision to submit a license renewal application, some have begun to investigate the feasibility of developing an life cycle management (LCM) program for a strategy to operate their plants efficiently, to investigate the financial benefit and safety implications of license renewal to operate their nuclear power plants beyond their current licensed periods, and to prepare a program plan for plant decommissioning. The LCM program includes economic, environmental, regulatory and technical aspects of continuing plant operations beyond the current license period. The Electric Power Research Institute (EPRI) has been supportive to assist utilities and owners groups in their research and development efforts to develop the technical requirements and the issues associated with important to license renewal structures. The focus of this paper is on the technical issues related to the evaluation of the material condition of the containment structure with respect to aging and the effective management of that aging.

    To assist in the long-term health management of residents and evaluate the health impacts after the Tokyo Electric Power Company's Fukushima Daiichi Nuclear Power Plant accident in Fukushima Prefecture, the Fukushima prefectural government decided to implement the Fukushima Health Management Survey. This report describes the results for residents aged 15 years or younger who received health checks and evaluates the data obtained from 2011 and 2012. The target group consisted of residents aged 15 years or younger who had lived in the evacuation zone. The health checks were performed on receipt of an application from any of the residents. The checks, which included the measurements of height, weight, blood pressure, biochemical laboratory findings, and peripheral blood findings, were performed as required. 1) A total of 17,934 (64.5%) and 11,780 (43.5%) residents aged 15 years or younger received health checks in 2011 and 2012, respectively. 2) In both years, a number of male and female residents in the 7-15 year age group were found to suffer from obesity, hyperlipidemia, hyperuricemia, or liver dysfunction. Furthermore, pediatric aged 15 years or younger were commonly observed to suffer from hypertension or glucose metabolic abnormalities. 3) A comparison of data from 2012 and 2011 demonstrated that both males and females frequently showed increased body height and decreased body weight in 2012. The prevalence of hypertension, glucose metabolic abnormalities, or high γ-GTP values in males and females in the 7-15 year age group in 2012 was lower than that in 2011. However, the prevalence of hyperuricemia among residents in the 7-15 year age group was higher in 2012 than in 2011. These results suggested that some residents aged 15 years or under who had lived in the evacuation zone had developed obesity, hyperlipidemia, hyperuricemia, liver dysfunction, hypertension, or glucose metabolic abnormalities. Therefore, we think that it is necessary to continue the health

    Significant safety improvements can be achieved in diesel-generator management related to aging, testing, and other important regulatory concerns. This paper reports on the progress of aging research related to nuclear service diesel generators, which developed data and information supporting the recommended safety improvements. The key to diesel-generator safety improvements is the development of a new balanced approach where testing, inspections, monitoring and trending, training, and maintenance all have appropriate importance. Safety improvement is projected in a management program that concurrently achieves three goals: first, the reduction of the fast-start stressor by regulatory and utility actions; second, the establishment of more appropriate testing and trending procedures; third, the adoption and use of reliability-centered maintenance activities. This paper describes the recommended safety improvements and the positive role of utility management in the process and outlines a new recommended regulatory approach. Diesel generator aging and wear is the subject of research sponsored by the Nuclear Plant Aging Research (NPAR) Program under the US Nuclear Regulatory Commission (NRC). Office of Nuclear Regulatory Research. The research was conducted by Pacific Northwest Laboratory (PNL), which is operated for the US Department of Energy by Battelle Memorial Institute. 4 refs., 1 fig., 1 tab

    HANARO is a 30 MW open pool type research reactor which has been operated for 16 years since its initial criticality in February 1995. It has been used for nuclear material testing, radioisotope production, neutron transmutation doping, nuclear activation analysis, and neutron scattering experiments. Recently, new facilities such as FTL (Fuel Transfer Loop) and CNS (Cold Neutron Source) were installed in the reactor. HANARO was originally designed to operate for at least 20 years under full power operating condition, but the actual life time is expected to be much more than the design lifetime by supporting with a safety reassessment based on realistic data and maintenance activities for an ageing management. The conducted inspections, maintenance activities, and the future plan of the ageing management for HANARO are presented in this paper. (author)

    Demographic change (ageing populations and falling birth rates) affects all industrialised nations, including Germany. Traditionally, the problems associated with managing numbers of older workers were mitigated by the Altersteilzeitgesetz in Germany. Under this law, firms were offered financial support by the government to offer early retirement (Müller-Camen et al. 2009). As these provisions came to an end in 2010, the need to find alternative solutions to displacing older workers, as well ...

    2006-01-01

    The aspects of plant ageing management (AM) gained increasing attention over the last ten years. Numerous technical studies have been performed to study the impact of ageing mechanisms on the safe and reliable operation of nuclear power plants. National research activities have been initiated or are in progress to provide the technical basis for decision making processes. The long-term operation of nuclear power plants is influenced by economic considerations, the socio-economic environment including public acceptance, developments in research and the regulatory framework, the availability of technical infrastructure to maintain and service the systems, structures and components as well as qualified personnel. Besides national activities there are a number of international activities in particular under the umbrella of the IAEA, the OECD and the EU. The paper will provide the summary on Nuclear Plant Life Management (PLIM) (or Ageing Management Program (AMP)) and Plant Life Extension (PLEX) development in USA and European countries. Also, insights from such effort currently performing in Slovenia will be discussed.(author)

    The majority of System, Structure and Components (SSC) in a nuclear power plants are designed to experience a service life, which is far above the intended design life. In most cases, only a small percentage of SSCs are subject to significant aging effects, which may affect the integrity or the function of the component. The process of aging management (AM) has the objective to monitor and control degradation effects which may compromise safety functions of the plant. And furthermore, to ensure, that testing and maintenance programs sufficiently provide preventive measures to control degradation effects. Safety-related aspects and the targeted high availability of the power plant as well as the requirements stipulated by German regulatory authorities prompted the operator of NPP ISAR to introduce an aging surveillance program. The NPP Isar as well as the German NPPs has to be following in the scope of aging management the KTA 1403 guideline. The NPP Isar surveillance program based on the KTA 1403 guideline covers the following aspects: - Scoping and screening of safety relevant Systems, Structures and Components (SSC); - Identification of possible degradation mechanisms for safety relevant SSC; - Ensure, that testing and maintenance programs sufficiently provide preventive measures to control degradation effects; - Transferability check of industry experience (internal and external events); - Annual preparation of an AM status report.

    Cost-effective power generation is becoming more important as the prices charged by power producers in the energy market continue to fall. To ease the cost situation there is a growing demand for innovative maintenance management methods which allow power plants to be economically operated over their entire lifetime. The purpose of a systematic ageing and plant life management program is to allow the lifetime of plant components to be planned, and to indicate when a component has reached the end of its effective lifetime before it fails. Another important function of such programs is to increase the availability of power plants as they age, and to enable implementation of a targeted maintenance strategy in terms of its economic and technical effect. Implementation of such programs requires the existence of detailed information concerning the status of the components as well as their operating conditions. Based on this information, an understanding of how the relevant ageing and degradation mechanisms work enables a prediction to be made concerning component lifetime. Advanced software programs provide such predictions at reasonable cost across all systems. (author)

    2016-04-01

    If aging is a physiological phenomenon-as maintained by the programmed aging paradigm-it must be caused by specific genetically determined and regulated mechanisms, which must be confirmed by evidence. Within the programmed aging paradigm, a complete proposal starts from the observation that cells, tissues, and organs show continuous turnover: As telomere shortening determines both limits to cell replication and a progressive impairment of cellular functions, a progressive decline in age-related fitness decline (i.e., aging) is a clear consequence. Against this hypothesis, a critic might argue that there are cells (most types of neurons) and organ parts (crystalline core and tooth enamel) that have no turnover and are subject to wear or manifest alterations similar to those of cells with turnover. In this review, it is shown how cell types without turnover appear to be strictly dependent on cells subjected to turnover. The loss or weakening of the functions fulfilled by these cells with turnover, due to telomere shortening and turnover slowing, compromises the vitality of the served cells without turnover. This determines well-known clinical manifestations, which in their early forms are described as distinct diseases (e.g., Alzheimer's disease, Parkinson's disease, age-related macular degeneration, etc.). Moreover, for the two organ parts (crystalline core and tooth enamel) without viable cells or any cell turnover, it is discussed how this is entirely compatible with the programmed aging paradigm.

    The management of diabetic foot ulcers can be optimized by using an interdisciplinary team approach addressing the correctable risk factors (ie, poor vascular supply, infection control and treatment, and plantar pressure redistribution) along with optimizing local wound care. Dermatologists can initiate diabetic foot care. The first step is recognizing that a loss of skin integrity (ie, a callus, blister, or ulcer) considerably increases the risk of preventable amputations. A holistic approach to wound assessment is required. Early detection and effective management of these ulcers can reduce complications, including preventable amputations and possible mortality.

    RSG GAS Research Reactor.30 MW, which is the biggest scientific investment made by the Indonesian Government, is operating safely for about 27 years. This research reactor has been built and developed since year 1983. Critical attainment reached first on July 1987 and ceremonial opened by president of RI on August 20{sup th} 1987. Operated with full energy of 30 MW reached first time on March 1992. It started becoming commercially operated since 1995. RSG-GAS has a maximum thermal energy of 30 MW and has neutron flux of averaged 10{sup 14} n/cm{sup 2}.sec coming from fissile reaction. RSG-GAS is a reactor with pool type with fuel of 19.75% enriched U{sub 3}O{sub 8}Al/U{sub 3}Si{sub 2}Al and burned up ratio up to 56%. RSG GAS has been built for scientific purpose by utilizing neutron beam instruments and isotope productions. Facilities allowing Neutron Activation Analysis for research and industry are both on-line. For affording the utilization or the reactor operation approaching the designed life, the progressive ageing management is being applied. This paper will address the ageing management based on the importance to safety and SSC replacement ease consideration, which is implemented on RSG GAS.

    Accident prevention is the first safety priority of both designers and operators. It is achieved through the use of reliable structures, components, systems and procedures in a plant operated by personnel who are committed to a strong safety culture. For future nuclear power plants, consideration of multiple failures and severe accidents will be achieved in a more systematic and complete way from the design stage. Defence in depth (DID) consists of a hierarchical deployment of different levels of equipment and procedures in order to maintain the effectiveness of physical barriers placed between radioactive materials and workers, the public or the environment, in normal operation, anticipated operational occurrences and, for some barriers, in accidents at the plant. The primary way of preventing accidents is to achieve a high quality in design, construction and operation of the plant, and thereby to ensure that deviations from normal operation are infrequent. The best way to meet these premises of effectiveness of the barriers and the Systems, Structures and Components (SSCs) is to develop an ageing management programme to prevent potential failures and accidents. In this work we will refer to the ageing management programme for Atucha I and Atucha II power plants and to the Atucha I spent fuel storage. (author)

    In China, the first two NPPs have operated over 15 years (QNPC) and 13 years (Dayabay). Now, most of Chinese NPPs have started their ageing management project. Steam generator (SG) is one of key safety important components for PWR and CANDU, which is selected as the first group of components to develop component ageing management system. QNPC and TQNPC have made some progress in this area. The basic SG ageing management system has been set up, and some application has been under way. To set up SG basic ageing management system, we start with (1) SG ageing mechanism analysis (2) Developing SG ageing management programme (3) Developing SG ageing management information system, SGAMDB (4) Ageing degradation assessment and remained life evaluation SG ageing mechanisms are classified as function degradation and material/structure degradation. The specific tables with unified format are used to analyze the ageing mechanism. The numbering requirements for ageing mechanism are developed to manage them in ageing information system. All ageing mechanisms are graded I and II and III based on its feasibility, impact on safety and operation experience, so that the key mechanisms are managed more strictly. SG ageing management programme (SGAMP), which is fundamental document for ageing management, provides the requirements for working process, what to do and when to do. SGAMP reviewing and improving requirements are as well included. SG ageing management database (SGAMDB) is the first component ageing management database for Chinese NPP, which have been installed and are in operation in QNPC and TQNPC. SG ageing degradation assessment and remained life evaluation are based on ageing mechanism, which includes integrity of tube bundle, integrity and remained fatigue life of key assemblies, and heat transfer capability degradation. Most NPPs at Chinese mainland have started their plant ageing and life management projects. Steam generator (SG), which is one of safety important

    The US Department of Energy, in cooperation with the Electric Power Research Institute and nuclear power plant utilities, has prepared ''Aging Management Guidelines'' (AMGs) for commodity types of equipment (e.g., pumps, electrical switchgear) important to license renewal. For the most part, this is also consistent with the Maintenance Rule, 10 CFR 50.65 (1991). AMGs concentrate on technical, (not licensing) issues and are directed toward systems engineers and plant maintenance staff. AMGs include a detailed summary of operating history, stressors, aging mechanisms, and various types of maintenance practices that can be combined to create effective programs that manage aging. All aging mechanisms were addressed; no attempt was made to limit the evaluation to aging mechanisms ''unique to license renewal,'' as defined in the License Renewal Rule, 10 CFR 54 (1991). The first AMG on Electrical Switchgear was published in July 1993. Six (6) additional AMGs will be published by the first quarter of calendar year 1994. It is anticipated that two more AMGs will be started in 1994. The seven ongoing AMG topics are as follows: (1) battery chargers, inverters and uninterruptible power supplies; (2) batteries, stationary; (3) heat exchangers; (4) motor control centers; (5) pumps; (6) switchgear, electric; (7) transformers, power and distribution. In Section 7, industry feedback regarding AMGs is discussed. Overall, the response has been very positive

    The Zero Energy Deuterium (ZED-2) Research Reactor first achieved criticality in 1960 September. Ageing of Systems, Structures and Components (SSCs) as well as the obsolescence of many original components had led to the Facility being in a reactive mode with respect to maintenance rather than a preventative maintenance mode. Through the implementation of an Ageing Management Plan to access the effects of Ageing Related Degradation Mechanisms (ARDMs) on SSCs and a Critical Spare Parts Obsolescence Plan (establishing new specifications for components, procurement of new components and building a replacement inventory) the Facility is returning to a preventative maintenance state rather than a reactive maintenance state. Upgrades and refurbishment of the original equipment and components is underway within the Facility. This paper describes the programs being carried out in the Facility and focuses on the upgraded nuclear electronics, renewed moderator level control system and spare parts inventory system. Implementation of the above mentioned programs will enable the Facility to continue to fulfill its mandate as an integral part of AECL's Vision and Strategic Outcome: 'To be a global partner in nuclear innovation' and that 'Canadians and the world receive energy, health, environmental and economic benefits from nuclear science and technology with confidence that nuclear safety and security are assured', respectively.

    This paper presents EDF practice about concrete structure ageing management, from the mechanisms analysis to the formal procedure which allows the French company to increase 900 MWe NPP lifetime until 40 years; it will also introduce its action plan for 60 years lifetime extension. This practice is based on a methodology which identifies every ageing mechanism; both plants feedback and state of the art are screened and conclusions are drawn up into an "ageing analysis data sheet". That leads at first to a collection of 57 data sheets which give the mechanism identification, the components that are concerned and an analysis grid which is designed to assess the safety risk. This analysis screens the reference documents describing the mechanism, the design lifetime hypotheses, the associated regulation or codification, the feedback experiences, the accessibility, the maintenance actions, the repair possibility and so one. This analysis has to lead to a conclusion about the risk taking into account monitoring and maintenance. If the data sheet conclusion is not clear enough, then a more detailed report is launched. The technical document which is needed, is a formal detailed report which summarizes every theoretical knowledge and monitoring data: its objective is to propose a solution for ageing management: this solution can include more inspections or specific research development, or additional maintenance. After a first stage on the 900 MWe units, only two generic ageing management detailed reports have been needed for the civil engineering part: one about reactor building containment, and one about other structures which focuses on concrete inflating reactions. The second stage consists on deriving this generic analysis (ageing mechanism and detailed reports) to every plant where a complete ageing report is required (one report for all equipments and structures of the plant, but specific for each reactor). This ageing management is a continuous process because the

    During operation of nuclear power plants, the quality of systems, structures and components may change as a result of ageing (conceptional ageing, technological ageing or physical ageing), which will affect the system quality. Ageing management is necessary to ensure safety and availability throughout the life of the systems. This necessitates a systematic, integrative and knowledge-based approach. Systems, structures and components are grouped according to their relevance for meeting the set goals. Ageing mangement should be process-oriented and should be integrated in the organisational procedure in cooperation with the safety manager. The procedure should follow the PDCA principle (plan - do - check - act). The data, documents, knowledge and evaluations required for ageing management are part of the knowledge base of the nuclear power station and are updated regularly. The efficiency of ageing management must be reassessed at regular intervals. (orig.)

  14. Belgium: National approach to ageing management

    International Nuclear Information System (INIS)

    2014-01-01

    In Belgium, the licenses for operation of the nuclear power plants granted by Royal Decree do not specify a fixed lifetime. The oldest plants, Doel 1&2 and Tihange 1, have been operational since 1975. The 2003 law regarding the exit from nuclear power limits the operation of nuclear power plants to 40 years. However, in October 2009, the Belgian government declared that they intended to make it legally possible for Doel 1&2 and Tihange 1 to operate until 2025, which would mean a total lifetime of 50 years (this statement was confirmed by the Belgian government in June 2012, only for the Tihange 1 plant). The Belgian Federal Agency for Nuclear Control (FANC) published in 2009 a strategic note regarding the requirements of long-term operation for Doel 1&2 and Tihange 1. Electrabel GDF SUEZ started its LTO programme in order to respond to these requirements. The LTO programme consisted of the following areas of concern, identified in the FANC strategic note: − Preconditions for long-term operation considering the IAEA expectations; − Ageing management; − Design re-evaluation; − Knowledge, competence and behaviour management. The note also stated that the long-term operation of the plants should be evaluated within the framework of the fourth ten-yearly PSR, based upon IAEA NS-G-2.10. As such a license renewal was not required for LTO and the LTO approval will be integrated in the approval process of the 4th PSR. In its strategic note, the Belgian Federal Agency for Nuclear Control explicitly states that the AMP has to be in conformity with the USNRC 10CFR54 and IAEA SRS 57

    The older population is becoming more important to our society everyday. These individuals are being studied for their past, present, and potential impact on markets and marketing. Evaluated as a user of products or services in the marketplace or an employee or volunteer within the marketing system, this segment is gaining a visibility and importance. An interview was conducted with five Nutrition Project Directors to obtain an overview of Federally Funded Nutrition Programs for the Elderly. The areas which were highlighted were service delivery, site activities, management styles, barriers to service, clientele composition, food planning and preparation, staffing, USDA funding, coordination, marketing, transportation, and volunteerism. The Second Quarter Service Provider Output Reports for 1991, which are compiled by the Nutrition Projects and submitted to the Area Agency on Aging, were utilized to obtain client profile information (Reports, 1991). The analysis sought to compare the programs offered in the five counties on a number of factors which could be quantified. It was hoped that by looking at the numerical ratios, and depicting them graphically, any trends or unique characteristics of the programs could be identified. In that the percentage of Florida's present elder population (17%) far exceeds the national average (12%) these findings could be utilized by nutrition programs outside of Florida to plan for future funds. Analysis of quantitative information on the five programs yielded information on cost comparisons and on services.

    NUR is a 1 MW, open pool reactor moderated and cooled by light water. It was commissioned in 1989. NUR is used for education and training in Nuclear Engineering and related topics for COMENA and National Scientific Community. It is also used to perform R and D works and services at national and regional levels. In this presentation, we describe the methodology and the main development activities related to the ageing management at NUR reactor. These activities include inspection actions and development actions to introduce modifications, to solve obsolescence issues in view to implement the required preventive and curative maintenance programs and to improve the performances of the installation. These actions involved mainly the Operation Assistance System of the Reactor (OAS), the secondary cooling loop, the cooling tower. A new OAS using a new technology and having more possibilities than the older one was introduced in the control system of the reactor. The OAS hardware structure, software structure and the main functions performed are presented. The second loop is entirely refurbished. Two new cooling towers are installed and connected to the main heat exchanger with new piping and valves. The architecture of this new installation is described and the performance assessed. Other actions which involve auxiliary systems like emergency electrical system, air pneumatic system and automatic fire extinguishing are presented.

    The condition of a physical system such as a radioactive materials transportation package can change as it ages. The degree to which aging effects are identified, prevented or mitigated will depend on the types of inspections and maintenance performed on the critical components of the system. Routine inspections and maintenance may not address degradation mechanisms that are difficult to observe and can act over long periods of time. Aging management is a systematic effort to ensure that the system performs as designed over its entire service life and that degradation mechanisms do not prematurely end the service life. The Nuclear Waste Management Division (NWMD) of Ontario Power Generation (OPG) has developed an Aging Management Procedure and began performing aging management assessments on its Type B(U) packages. This paper discusses the Procedure and briefly describes the aging management assessment performed on the Roadrunner Transportation Package to demonstrate a practical application of the aging management process

    2013-01-01

    A United States Government Accountability Office (GAO) review of twelve NASA programs found widespread parts quality problems contributing to significant cost overruns, schedule delays, and reduced system reliability. Direct part marking with Data Matrix symbols could significantly improve the quality of inventory control and parts lifecycle management. This paper examines the feasibility of using direct part marking technologies for use in future NASA programs. A structural analysis is based on marked material type, operational environment (e.g., ground, suborbital, Low Earth Orbit), durability of marks, ease of operation, reliability, and affordability. A cost-benefits analysis considers marking technology (label printing, data plates, and direct part marking) and marking types (two-dimensional machine-readable, human-readable). Previous NASA parts marking efforts and historical cost data are accounted for, including inhouse vs. outsourced marking. Some marking methods are still under development. While this paper focuses on NASA programs, results may be applicable to a variety of industrial environments.

    Full text: Cable polymer aging and condition monitoring is being studied in detail under the Nuclear Energy Plant Optimization Program (NEPO) that is co-sponsored by the U.S. Department of Energy and EPRI. Significant advances in modeling of polymer aging and condition monitoring have occurred and continue to be developed. The activities include: Analysis of the linearity of the Arrhenius model to room temperature; Development of a wear-out technique for determining remaining life of cable polymers; Determination of the aging fragility point for composite EPR/CSPE insulation with respect to LOCA function; Development of visual/tactile training aids for cable assessment; Development of a totally new nuclear magnetic resonance condition monitoring technique; Assessment of existing techniques with regard to repeatability, accuracy and ease of use. Through use of highly precise oxygen consumption experiments, the linearity of the Arrhenius model is being evaluated. In these experiments, polymer is placed in vials with a known amount of oxygen and aged at much lower temperatures than is possible with standard accelerated aging techniques. aging results are possible at room temperature. The technique is being applied to commonly used insulation and jacket polymers. The wear-out technique allows highly non-linear aging behavior to be made linear. The wearout point of a polymer is determined through high-rate aging and use of a condition monitoring technique to establish the end point. Then, micro-samples of cable that have been naturally aged are subjected to high rate aging to the same end point. The ratio of the remaining high rate aging period to the total high rate aging time provides a linear indication of the remaining service time. Initial screening of nuclear plant cable systems can use visual/tactile techniques to identify cable that has aged significantly. Training aids have been developed by developing sets of specimens with accelerated aging ranging from none

    2010-10-15

    This Safety Guide was developed under the IAEA programme for safety standards for research reactors, which covers all the important areas of research reactor safety. It supplements and elaborates upon the safety requirements for ageing management of research reactors that are established in paras 6.68-6.70 and 7.109 of the IAEA Safety Requirements publication, Safety of Research Reactors. The safety of a research reactor requires that provisions be made in its design to facilitate ageing management. Throughout the lifetime of a research reactor, including its decommissioning, ageing management of its structures, systems and components (SSCs) important to safety is required, to ensure continued adequacy of the safety level, reliable operation of the reactor, and compliance with the operational limits and conditions. Managing the safety aspects of research reactor ageing requires implementation of an effective programme for the monitoring, prediction, and timely detection and mitigation of degradation of SSCs important to safety, and for maintaining their integrity and functional capability throughout their service lives. Ageing management is defined as engineering, operation, and maintenance strategy and actions to control within acceptable limits the ageing degradation of SSCs. Ageing management includes activities such as repair, refurbishment and replacement of SSCs, which are similar to other activities carried out at a research reactor in maintenance and testing or when a modification project takes place. However, it is important to recognize that effective management of ageing requires the use of a methodology that will detect and evaluate ageing degradation as a consequence of the service conditions, and involves the application of countermeasures for prevention and mitigation of ageing degradation. The objective of this Safety Guide is to provide recommendations on managing ageing of SSCs important to safety at research reactors on the basis of international

Managing the safety aspects of research reactor ageing requires implementation of an effective programme for the monitoring, prediction, and timely detection and mitigation of degradation of SSCs important to safety, and for maintaining their integrity and functional capability throughout their service lives. Ageing management is defined as engineering, operation, and maintenance strategy and actions to control within acceptable limits the ageing degradation of SSCs. Ageing management includes activities such as repair, refurbishment and replacement of SSCs, which are similar to other activities carried out at a research reactor in maintenance and testing or when a modification project takes place. However, it is important to recognize that effective management of ageing requires the use of a methodology that will detect and evaluate ageing degradation as a consequence of the service conditions, and involves the application of countermeasures for prevention and mitigation of ageing degradation. The objective of this Safety Guide is to provide recommendations on managing ageing of SSCs important to safety at research reactors on the basis of international

    2002-01-01

    Ageing of nuclear power plants means evolution of material or equipment properties on one side, and evolution of personnel skill and procedure adequacy on the other side, both of which, after a certain time, may not be compatible with the required safety provisions, or with an economic operation of the plant. Repair or replacement of components, as well as change in service conditions for a better compatibility with component reduced capabilities can be used to mitigate ageing effects. The paper summarises the results of a study conducted in this field with the support of the European Commission. It presents: the synthesis of the work done under international auspices, and in the European context; the comparison of ageing management approaches used in several European countries with international recommendations; the summary of the various potential phenomena and their governing parameters, the methods of in-service ageing identification and possible mitigation methods; illustrative ageing management practices, taking material ageing aspects as examples. Concerning the first topic, the European report identifies 56 OECD and IAEA reports on ageing management issues, 35 being summarised in an appendix to the report. It also identifies numerous European and international studies covering topics of interest to ageing and Plant Life management. ageing management approaches have been considered from the regulatory point of view and from the utilities management point of view. Contributors to the study have identified a general consensus in Europe, with no limited time operating authorisation, the safety being a utility responsibility under continuous surveillance by the regulatory authority. Practical ageing management methods include: periodic safety reviews (PSR), a ten years periodicity being a common practice, completed by continuous ageing management taking into account safety and industrial anticipation needs; the implementation of life-time management programmes

    Full Text Available The main aim of this research is to highlight age management within Slovenian enterprises from the viewpoint of older employees by finding out what influences older employees to decide “should I stay or should I go”. The empirical research methodology is based on mixed strategy of approaching organizations (employees, which means that the quantitative (factor analysis, cluster analysis, correlation, regression, descriptive statistics and frequency distributions and qualitative parts (in-depth interviews analysis of research were conducted simultaneously. The results of the research indicate that there are in fact two groups of older employees, which can be referred to as “susceptible” and “insusceptible” in terms of how the employer can affect their decisions. “The unsusceptible” have already decided to retire as soon as possible and they cannot be influenced by any employer measure. On the other hand, “the susceptible” employees are sensitive to employers’ measures aimed at prolonging their working lives. Besides, a regression analysis confirmed a statistically significant correlation between the inclination towards extending one’s employment period and the susceptibility to the employer measures. It can thus be concluded that, through age management measures, an employer has an impact on an extended employment period of older employees. However, employers should be interested primarily in those employees who are inclined towards extending their working lives.

    Changes in the skin that occur in the elderly may put them at increased risk for altered percutaneous penetration from pharmacotherapy along with potential adverse effects. Skin factors that may have a role in age-related percutaneous penetration include blood flow, pH, skin thickness, hair and pore density, and the content and structure of proteins, glycosaminoglycans (GAGs), water, and lipids. Each factor is examined as a function of increasing age along with its potential impact on percutaneous penetration. Additionally, topical drugs that successfully overcome the barrier function of the skin can still fall victim to cutaneous metabolism, thereby producing metabolites that may have increased or decreased activity. This overview discusses the current data and highlights the importance of further studies to evaluate the impact of skin factors in age-related percutaneous penetration.

    2013-01-01

    A United States Government Accountability Office (GAO) review of twelve NASA programs found widespread parts quality problems contributing to significant cost overruns, schedule delays, and reduced system reliability. Direct part-marking with Data Matrix symbols could significantly improve the quality of inventory control and parts lifecycle management. This paper examines the feasibility of using 15 marking technologies for use in future NASA programs. A structural analysis is based on marked material type, operational environment (e.g., ground, suborbital, orbital), durability of marks, ease of operation, reliability, and affordability. A cost-benefits analysis considers marking technology (data plates, label printing, direct part marking) and marking types (two-dimensional machine-readable, human-readable). Previous NASA parts marking efforts and historical cost data are accounted for, including in-house vs. outsourced marking. Some marking methods are still under development. While this paper focuses on NASA programs, results may be applicable to a variety of industrial environments.

    Increased utilization of medical imaging in the early part of the last decade has resulted in numerous efforts to reduce associated spending. Recent initiatives have focused on managing utilization with radiology benefits managers and real-time order entry decision support systems. Although these approaches might seem mutually exclusive and their application to radiology appears unique, the historical convergence and broad acceptance of both programs within the pharmacy sector may offer parallels for their potential future in medical imaging. In this second installment of a two-part series, anticipated trends in radiology utilization management are reviewed. Perspectives on current and future potential roles of radiologists in such initiatives are discussed, particularly in light of emerging physician payment models.

    The HANARO, an open-tank-in-pool type research reactor of 30MWth power in Korea, has operated for 8 years since its initial criticality in February of 1995. The reactor power has been gradually increased to 24 MWth through the service period. Therefore the reactor age is very young from the viewpoint of the ageing effect on the reactor structure and components by neutron irradiation considering the expected reactor lifetime. But, we have a few programs to manage the ageing from the aspect of design lifetime of reactor components. This paper summarizes the overall progress and plan for the ageing management for the reactor components including lifetime extension and design improvement, remote measurements and in-service inspections. The shutoff units and control absorber units have aged more rapidly than other structures or components because the number of rod drop cycles was higher than expected at the design stage. The system commissioning tests, periodic performance tests, and weekly operation for the stable supply of medical radioisotopes overriding the normal cycle operation have contributed to the high frequency of rod drop. Therefore, we have instituted a program to extend the lifetime of the shutoff units and the control absorber units. This program includes an endurance test to verify the performance for the extended number of drops and the management of shutdown methods to minimize the drop cycles for both the shutoff units and the control absorber units. The program also includes the design improvement of the damper mechanism of the control absorber units to reduce the impact force caused by rod drop. The inner shell of the reflector vessel surrounding the core is the most critical part from the viewpoint of neutron irradiation. The periodic measurement of the dimensional change in the vertical straightness of the inner shell is considered as one of the in-service inspections. We developed a few tools and verified the performance to measure the

    A thorough evaluation of headache in children and adolescents is necessary to make the correct diagnosis and initiate treatment. In part 1 of this article (Özge et al. in J Headache Pain, 2010), we reviewed the diagnosis of headache in children and adolescents. In the present part, we will discuss therapeutic management of primary headaches. An appropriate management requires an individually tailored strategy giving due consideration to both non-pharmacological and pharmacological measures. Non-pharmacological treatments include relaxation training, biofeedback training, cognitive-behavioural therapy, different psychotherapeutic approaches or combinations of these treatments. The data supporting the effectiveness of these therapies are less clear-cut in children than in adults, but that is also true for the data supporting medical treatment. Management of migraine and TTH should include strategies relating to daily living activities, family relationships, school, friends and leisure time activities. In the pharmacological treatment age and gender of children, headache diagnosis, comorbidities and side effects of medication must be considered. The goal of symptomatic treatment should be a quick response with return to normal activity and without relapse. The drug should be taken as early as possible and in the appropriate dosage. Supplementary measures such as rest in a quiet, darkened room is recommended. Pharmaco-prophylaxis is only indicated if lifestyle modification and non-pharmacological prophylaxis alone are not effective. Although many prophylactic medications have been tried in paediatric migraine, there are only a few medications that have been studied in controlled trials. Multidisciplinary treatment is an effective strategy for children and adolescents with improvement of multiple outcome variants including frequency and severity of headache and school days missed because of headache. As a growing problem both children and families should be informed

    2007-01-01

    Storage of nuclear fuel after it has been discharged from reactors has become the leading spent fuel management option. Many storage facilities are being required to operate longer than originally anticipated. Aging is a term that has emerged to focus attention on the consequences of extended operation on systems, structures, and components that comprise the storage facilities. The key to mitigation of age-related degradation in storage facilities is to implement effective strategies to understand and manage aging of the facility materials. A systematic approach to preclude serious effects of age-related degradation is addressed in this paper, directed principally to smaller facilities (test and research reactors). The first need is to assess the materials that comprise the facility and the environments that they are subject to. Access to historical data on facility design, fabrication, and operation can facilitate assessment of expected materials performance. Methods to assess the current condition of facility materials are summarized in the paper. Each facility needs an aging management plan to define the scope of the management program, involving identification of the materials that need specific actions to manage age-related degradation. For each material identified, one or more aging management programs are developed and become part of the plan Several national and international organizations have invested in development of comprehensive and systematic approaches to aging management. A method developed by the US Nuclear Regulatory Commission is recommended as a concise template to organize measures to effectively manage age-related degradation of storage facility materials, including the scope of inspection, surveillance, and maintenance that is needed to assure successful operation of the facility over its required life. Important to effective aging management is a staff that is alert for evidence of materials degradation and committed to carry out the aging

    The aim of nuclear power plant ageing management is to maintain an adequate safety level throughout the lifetime of the plant. In ageing studies, the reliability of components, systems and structures is evaluated taking into account the possible time-dependent degradation. The phases of ageing analyses are generally the identification of critical components, identification and evaluation of ageing effects, and development of mitigation methods. This thesis focuses on the use of reliability methods and analyses of plant- specific operating experience in nuclear power plant ageing studies. The presented applications and method development have been related to nuclear power plants, but many of the approaches can also be applied outside the nuclear industry. The thesis consists of a summary and seven publications. The summary provides an overview of ageing management and discusses the role of reliability methods in ageing analyses. In the publications, practical applications and method development are described in more detail. The application areas at component and system level are motor-operated valves and protection automation systems, for which experience-based ageing analyses have been demonstrated. Furthermore, Bayesian ageing models for repairable components have been developed, and the management of ageing by improving maintenance practices is discussed. Recommendations for improvement of plant information management in order to facilitate ageing analyses are also given. The evaluation and mitigation of ageing effects on structural components is addressed by promoting the use of probabilistic modelling of crack growth, and developing models for evaluation of the reliability of inspection results.

    Older people often experience loss of appetite and/or decreased food intake that, unavoidably, impact energy metabolism and overall health status. The association of age-related nutritional deficits with several adverse outcomes has led to the recognition of a geriatric condition referred to as "anorexia of aging." Anorexia is an independent predictor of morbidity and mortality both in the community and across clinical settings. Multidimensional interventions within personalized care plans currently represent the most effective option to ensure the provision of adequate amounts of food, limit weight loss, and prevent adverse health outcomes in older adults.

    The purpose of this fourth part of the COLLABORATE© article series provides an expansion and application of previously presented concepts pertaining to the COLLABORATE paradigm of professional case management practice. The model is built upon a value-driven foundation that: PRIMARY PRACTICE SETTING(S):: Applicable to all health care sectors where case management is practiced. As an industry, health care continues to evolve. Terrain shifts and new influences continually surface to challenge professional case management practice. The need for top-performing and nimble professionals who are knowledgeable and proficient in the workplace continues to challenge human resource departments. In addition to care setting knowledge, professional case managers must continually invest in their practice competence toolbox to grow skills and abilities that transcend policies and processes. These individuals demonstrate agility in framing (and reframing) their professional practice to facilitate the best possible outcomes for their clients. Therefore, the continued emphasis on practice competence conveyed through the performance management cycle is an essential ingredient to performance management focused on customer service excellence and organizational improvement. Professional case management transcends professional disciplines, educational levels, and practice settings. Business objectives continue to drive work process and priorities in many practice settings. However, competencies that align with regulatory and accreditation requirements should be the critical driver for consistent, high-quality case management practice. Although there is inherent value in what various disciplines bring to the table, this advanced model unifies behind case management's unique, strengths-based identity instead of continuing to align within traditional divisions (e.g., discipline, work setting, population served). This model fosters case management's expanding career advancement opportunities.

    Full Text Available The simplest definition of heart failure is "A condition in which the heart fails to discharge its contents adequately". Even though the prevalence is quoted at 4 - 20 / 1000 population, in the elderly above 65 years, the figures may exceed 100/1000. After the age of 45, it is found that the relative incidence of heart failure which is approximately 1 - 5 /1000, double for each decade of life. As modernization increases and healthcare improves over the years, the prevalence of heart failure also increases due to the increase in longevity of individuals.

    The PUSPATI TRIGA reactor (RTP) at Malaysian Nuclear Agency which has been operating for 29 years now faces increasingly serious aging problems. Many components are obsolete whereas genuine parts are no longer in the market. Currently, the aging problem is addressed through periodic maintenance on all systems, structures and components (SSC). As a holistic measure, the Aging Management Program (AMP) was formulated to solve the problems from the grassroots. This paper describes the first stage of the AMP which identifies the strengths and capabilities. This includes identifying the types of aging, responsible parties and relationship between aging problems and safety of RTP. (author)

    Safety is an condition which must always reached in management a nuclear reactor, from construction stage, operation until the decommissioning have processed. The safety of reactor operation is closely related to the reliability of components, structures and systems (KSS) of the nuclear reactor. All reactors' KSS will experience of ageing and then degrade system reliability level. G.A. Siwabessy Multipurpose Reactor (RSG-GAS) is high power research reactor which have been operating for sixteen years long. Comprehensive evaluation of ageing process that happened in RSG-GAS has not conducted yet. Meanwhile, in general, for all research reactor type there are safety requirements from IAEA related to the ageing, even in design, development, operation and extending operation life. To starting and racing the comprehensive evaluation of ageing in RSG-GAS, the research to compile an integrated Ageing Management Document as guidance in implementation of ageing management in RSG-GAS was conducted. From result of this research, the Ageing Management Document of RSG-GAS has been compiled. Compilation of the document is carried out by embracing approach of compromise of ageing management of research reactor and power reactor. (author)

    2013-02-01

    This month we have discussed the fundamentals of patient flow and its related theories. We reviewed the concepts of demand and capacity management as they apply to the hospital setting. Patient flow requires daily diligence and attention. It should not be something focused on only on busy days, but should be managed each and every day. By taking a proactive approach to patient flow, the number of days your hospital will be bottlenecked can be reduced. Patient flow needs to be part of the daily activities of every case management department and should be factored in as a core role and function in a contemporary case management department. Patient flow needs to be addressed at the patient, departmental, and hospital level. In next month's issue we will continue our discussion on patient flow with a detailed review of specific examples that any case management department can use. We will also review all the departments and disciplines that contribute to patient flow and their role in it.

    1995-01-01

    OSIRIS, one of the French CEA research reactors (Saclay, France), achieved criticality for the first time on July 1966. During the 29 running years OSIRIS was mainly devoted to production and technological irradiations. To satisfy these objectives, OSIRIS is equipped by different test facilities allowing: the long time irradiation of different material including fuel rods, reactor vessel materials, fusion reactor components; the power ramps of fuel rods; the activation analysis; the neutron-radiography of materials and test sections... All the foreseen irradiation programmes will only be possible if safety and high performances of the reactor are guaranteed. That is why a continuous maintenance and improvement programme has taken place during the whole life of the reactor. This paper gives an overview of this programme, mainly about the part conducted during the last years. Details about characteristics of the reactor, history of experiments, maintenance programme, instrumentation and control system, electrotechnical low voltage supply network, decay tanks and water purification system are summarized. The paper focuses on the refurbishment or the replacement of the main components connected to the continuous maintenance programme to guarantee the reliability, the safety and the high performances of the reactor.

    2008-01-01

    Chemical Cleaning an essential part of Steam Generator asset management accumulation of deposits is intrinsic for the operation of Steam Generators in PWRs. Such depositions often lead to reduction of thermal performance, loss of component integrity and, in some cases to power restrictions. Accordingly removal of such deposits is an essential part of the asset management of the Steam Generators in a Nuclear Power Plant. Every plant has its individual condition, history and constraints which need to be considered when planning and performing a chemical cleaning. Typical points are: - Sludge load amount and constitution of the deposits - Sludge distribution in the steam generator - Existing or expected corrosion problems - Amount and tendency of fouling for waste treatment Depending on this points the strategy for chemical cleaning shall be evolved. the range of treatment starts with very soft cleanings with a removal of approx 100 kg per steam generator and goes to a full scale cleaning which can remove up to several thousand kilograms of deposits from a steam generator. Depending on the goal to be achieved and the steam generator present an adequate cleaning method shall be selected. This requires flexible and 'customisable' cleaning methods that can be adapted to the individual needs of a plant. Such customizing of chemical cleaning methods is an essential factor for an optimized asset management of the steam generator in a nuclear power plant

  19. NPAR [Nuclear Plant Aging Research] approach to managing aging in nuclear power plants

    International Nuclear Information System (INIS)

    Christensen, J.A.

    1989-01-01

    Over the past 5 years, the Nuclear Plant Aging Research program (NPAR) has been devoted to developing technical understanding of the time dependent processes that, through deterioration of components, systems, or structures (C/S/S), can reduce safety margins in nuclear power plants. A major and necessary element of the program involves the application of this basic knowledge in defining functional approaches to managing aging by anticipating and mitigating important deterioration processes. Fundamental understanding and characterization of aging processes are being accomplished through NPAR-sponsored research projects, review and analysis of aging related information, integration of NPAR results with those from industry and other aging studies, and interfacing of all of these with the existing body of codes, standards and regulatory instruments that convey aging-related guidance to NPP licensees. Products of these efforts are applied to structuring and providing aging-related technical recommendations in forms that are useful in: (1) developing and implementing good aging management practices, (2) developing regulatory guidance and requirements for understanding and managing aging during normal plant operations and in support of license renewal, and (3) planning and implementing other regulatory actions and initiatives in which aging-related concerns have a bearing on scope or priority

  20. The use of research results for effective aging management

    1989-01-01

    The study of the degradation of structures, components, and systems due to aging is an important ongoing area of research in the nuclear industry. Efforts by the U.S. Nuclear Regulatory Commission (NRC) and the utility industry, through organizations such as the Electric Power Research Institute (EPRI), have produced substantial research results that can be used by inspectors and operators to effectively understand and manage the aging of nuclear power plants. One of the primary objectives of the NRC's Nuclear Plant Aging Research (NPAR) Program is to determine how aging affects the safety of nuclear power plants. This program uses operating experience, testing, and engineering analysis to identify failures caused by age-related degradation. Useful information on aging has also resulted from research being performed by the industry to support plant-life extension (PLEX). The EPRI program, for instance, is directed toward the resolution of issues related to materials and components. Degradation of equipment and systems due to aging can occur which, if unmitigated, could result in reduction of the nuclear power plant safety margin as the plant ages. This paper describes how aging research results may be used by plant operating management to effectively address the aging issue and by inspectors responsible for monitoring plant activities and programs

  1. Inventory management of spare parts in an energy company

    2012-06-15

    We address a problem of inventory management of spare parts in the context of a large energy company, producer of oil and gas. Spare parts are critical for assuring operational conditions in offshore platforms. About 200,000 different items are held in several inventory plants. The inventory system implemented at the company corresponds to a min-max system. The control parameters are decided based mainly on the expert judgment of the planners. Also, though the inventory plants can in practice be supplied from each other, the inventory planning is performed separately by the plant planners. This is because of different ownership structures where the studied company has the operative responsibility. The company is pursuing a system in which all planners conform to the same inventory management approach and evaluation, as well as being more cost efficient. Our work focuses on supporting this goal. We apply methods to decide the inventory control parameters for this system under a service level constraint. The methodology we use distinguishes unit-size and lot-size demand cases. We perform computational experiments to find control parameters for a sample of items. After the control parameters are found, we use them to explore the impact of risk pooling among the plants and inaccuracy arising from duplicate item codes.(Author)

    2015-01-01

    Case management directors are in a dynamic position to affect the transition of care of patients across the continuum, work with all levels of providers, and support the financial well-being of a hospital. Most importantly, they can drive good patient outcomes. Although the position is critical on many different levels, there is little to help guide a new director in attending to all the "moving parts" of such a complex role.This is Part 2 of a two-part article written for case management directors, particularly new ones.Part 1 covered the first 4 of 7 tracks: (1) Staffing and Human Resources, (2) Compliance and Accreditation, (3) Discharge Planning and (4) Utilization Review and Revenue Cycle. Part 2 addresses (5) Internal Departmental Relationships (Organizational), (6) External Relationships (Community Agency), and (7) Quality and Program Outcomes.This article attempts to answer the following questions: : The information is most meaningful to those case management directors who work in either stand-alone hospitals or integrated health systems and have frontline case managers (CMs) reporting to them. Part 1 found that case management directors would benefit from further research and documentation of "best practices" related to their role, particularly in the areas of leadership and management. The same conclusion applies to Part 2, which addresses the director's responsibilities outside her immediate department. Leadership and management skills apply as well to building strong, productive relationships across a broad spectrum of external organizations that include payer, provider, and regulatory agencies. At the same time, they must also develop the skills to positively influence the revenue cycle and financial health of both the organization for which they work and those to whom they transition patients. A director of case management with responsibility for transitions of care has more power and influence over patient safety than is commonly known. Few of the

    2005-01-01

    According to the requirements of NNSA, for Chinese operational NPPs periodical safety review (PSR) should be carried out every 10 years. Ageing management is one of the important safety factors to be reviewed. Entrusted by Qinshan Nuclear Power Plant (QNPP), Shanghai Nuclear Engineering Research and Design Institute (SNERDI) carried out the ageing management review (AMR), as a part of the first PSR of QNPP, from 2001 to 2003. This paper summarizes the methodology of the AMR process, including screening of critical components and structures, identification of main ageing mechanisms and their indicators and the tabulated review process, etc. 15 components and structures, hereafter referred as equipment, were selected as review objects based on their significance of safety, replaceability and cost-benefit considerations. To these objects, the main ageing mechanisms and relevant ageing indicators were identified according to specific working and environmental condition, design and manufacture information, operation and maintenance history, etc. The review can be divided into two parallel parts, the review for specific equipment and the review for overall management procedures and their implementation. To typical components, such as RPV and SG, fatigue analysis based on operational transient accounting was carried out to observe the actual safety margins. Through the review, the weaknesses in ageing management and potential threats to structural integrity were identified and thus continued improvement can be made in the next period of 10 years.

    Full Text Available In the recent years there has been a particularly strong pressure on changing old structures and management models in research institutes. Contemporary research institutes are scientific units which are commercial in character – almost 80% of funds come from companies and contractual research activity and services. They are the basic sector of science aiming at cooperation with the economy, applied and innovative research. In order to maintain the current and start new cooperation it is necessary to pay particular attention to maintaining, improving and exposing high level of quality of conducted activity. Taking into consideration the necessity of carrying out ever more complex research projects, conducting activity requiring fast reaction to change, risk analysis, which is assessed every year by the Ministry of Science and Higher Education – it seems that it is necessary to apply tools supporting the assessment of quality. In the proposed three-aspect perspective the following scopes of activity are emphasized: implemented quality management systems, area of scientific information and the sphere of cooperation with the client. This article constitutes the continuation of the subjects discussed in the first part – an extension of issues associated with the scope of responsibilities of particular Sections of the proposed Quality Management Platform in research institutes.

    2017-08-01

    The aim of this study was to evaluate the effect of cynical distrust on mortality in middle-aged and aging men. The analysis is based on Kuopio Ischemic Heart Disease study, follow-up from 1984 to 2011. Sample consisted of 2682 men, aged 42-61 years at baseline. Data on mortality was provided by the National Death Registry, causes of death were classified by the National Center of Statistics of Finland. Cynical distrust was measured at baseline using Cynical Distrust Scale. Survival analyses were conducted using Cox regression models. In crude estimates after 28 years of follow-up, high cynical distrust was associated with 1.5-1.7 higher hazards for earlier death compared to low cynical distrust. Adjusted for conventional risk factors, high cynical distrust was significantly associated regarding CVD-free men and CVD mortality, while non-CVD mortality in study sample was consistently but not significantly associated. The risk effects were more expressed after 12-20 years rather than in earlier or later follow-up. To conclude, high cynical distrust associates with increased risk of CVD mortality in CVD-free men. The associations with non-CVD mortality are weaker and not reach statistical significance.

    2012-01-01

    A Plant-wide and systematic Aging and Plant Life Management is essential for the safe operation and/or availability of nuclear power plants. The Aging Management (AM) has the objective to monitor and control degradation effects for safety relevant Systems, Structures and Components (SSCs) which may compromise safety functions of the plant. The Plant Life Management (PLM) methodology also includes aging surveillance for availability relevant SSCs. AM and PLM cover mechanical components, electrical and I and C systems and civil structures All Aging and Plant Life Management rules call for a comprehensive approach, requiring the systematic collection of various aging and safety relevant data on a plant-wide basis. This data needs to be serviced and periodically evaluated. Due to the complexity of the process, this activity needs to be supported by a qualified software tool for the management of aging relevant data and associated documents (approx. 30 000 SSCs). In order to support the power plant operators AREVA NP has developed the software tool COMSY. The COMSY software with its integrated AM modules enables the design and setup of a knowledge-based power plant model compatible to the requirements of international and national rules (e.g. IAEA Safety Guide NS-G-2.12, KTA 1403). In this process, a key task is to identify and monitor degradation mechanisms. For this purpose the COMSY tool provides prognosis and trending functions, which are based on more than 30 years of experience in the evaluation of degradation effects and numerous experimental studies. Since 1998 COMSY has been applied successfully in more than fifty reactor units in this field. The current version 3.0 was revised completely and offers additional AM functions. All aging-relevant component data are compiled and allocated via an integrated power plant model. Owing to existing interfaces to other software solutions and flexible import functions, COMSY is highly compatible with already existing data

    Aging phenomena was raised as an important issue at GAS-MPR after having some component degradation reported within its ten years operational record. This phenomena was anticipated by developing a program of aging management, where its purpose is to prevent an enlargement of degradation of the systems and components and failure. The aging managements include identification of system and component which have aging process enlargement and impact to the reactor operational safety, developing operational operation and maintenance practices, developing operational and maintenance data base, developing predictive maintenance program, and identifying and studying method and technology for inspection, testing, and surveillance. The result of studying on method and technology of testing, surveillance, and diagnostic conclude that FFT based noise spectrum analysis can be used to detect an anomaly of system and component performance. This analysis will be developed in the future using Auto Regressive Method, Kalman Filter, and Neural Network. (author)

    A nuclear power plant's maintenance program is the principal vehicle through which age-related degradation is managed. Over the past two years, the NRC [Nuclear Regulatory Commission] has evaluated the maintenance program of every nuclear power plant in the U.S. The reports issued on these in-depth team inspections have been reviewed to ascertain the strengths and weaknesses of the programs as related to the need to understand and manage the effects of aging on nuclear power plant systems, structures, and components. Selected results of this review are presented in this paper, including examples of inspection and monitoring techniques successfully used by utilities to detect degradation due to aging. Attributes of plant maintenance programs where the NRC inspectors felt that improvement was needed to properly address the aging issue are also discussed. 6 refs., 1 tab

    2013-02-01

    The purpose of this report is to describe programs and tools for assessment of accomplished and documented qualification with respect to ageing of electrical equipment and for development of complimentary ageing management programs. In addition to description of complete programs for management of ageing, tools for validation of the status with regard to ageing of installed ('old') equipment and, where needed, for complementation of their qualification are also included. The report is restricted to safety related equipment containing ageing sensitive parts, mainly organic materials. To this category belong cables and cable joints and a number of equipment containing oils, seals (o-rings), etc. For equipment located in the containment, the possibilities of continuous supervision are limited. The accessibility for regular inspections is also limited in many cases. The main part of this report deals with the qualification of such equipment. Some safety related equipment outside the containment can be located in areas where they are subjected to high temperature and other excessive environmental stresses during normal operation and in areas affected by an accident. Therefore, some material is given also on qualification of equipment located outside containment with better possibilities for frequent inspection and supervision. Part 1 of the report is an executive summary with a general review of the methodologies and their application. The more detailed description of the programs and underlying material, useful data, etc. is given in Part 2

    The Nuclear Materials Storage Facility (NMSF) at the Los Alamos National Laboratory (LANL) was a Fiscal Year (FY) 1984 line-item project completed in 1987 that has never been operated because of major design and construction deficiencies. This renovation project, which will correct those deficiencies and allow operation of the facility, is proposed as an FY 97 line item. The mission of the project is to provide centralized intermediate and long-term storage of special nuclear materials (SNM) associated with defined LANL programmatic missions and to establish a centralized SNM shipping and receiving location for Technical Area (TA)-55 at LANL. Based on current projections, existing storage space for SNM at other locations at LANL will be loaded to capacity by approximately 2002. This will adversely affect LANUs ability to meet its mission requirements in the future. The affected missions include LANL's weapons research, development, and testing (WRD ampersand T) program; special materials recovery; stockpile survelliance/evaluation; advanced fuels and heat sources development and production; and safe, secure storage of existing nuclear materials inventories. The problem is further exacerbated by LANL's inability to ship any materials offsite because of the lack of receiver sites for mate rial and regulatory issues. Correction of the current deficiencies and enhancement of the facility will provide centralized storage close to a nuclear materials processing facility. The project will enable long-term, cost-effective storage in a secure environment with reduced radiation exposure to workers, and eliminate potential exposures to the public. This document provides Part I - Design Concept which describes the selected solution, and Part II - Project Management which describes the management system organization, the elements that make up the system, and the control and reporting system

    2002-01-01

    The reactor coolant system (RCS) mechanical components that require an aging management review for license renewal include the primary loop piping and associated connections to other support systems, reactor vessel, reactor vessel internals, pressurizer. steam generators, reactor coolant pumps, and all other inter-connected piping, pipe fittings, valves, and bolting. All major RCS components are located inside the reactor building. Based on the evaluation findings of recently submitted license renewal applications for pressurized water reactors, this paper presents the plant programs and/or activities proposed by the applicants to manage the effects of aging. These programs and/or activities provide reasonable assurance that the intended function(s) of these mechanical components will be maintained for the period of extended operation. The license renewal application includes identification of RCS subcomponents that are within the scope of license renewal and are vulnerable to age-related degradation when exposed to environmental and operational conditions. determination of the effects of aging on their intended safety functions. and implementation of the aging management programs and/or activities including both current and new programs. Industry-wide operating experience, including generic communication by the NRC, is part of the aging management review for the RCS components. In addition, this paper discusses time-limited aging analyses associated with neutron embrittlement of the reactor vessel beltline region and thermal fatigue

    Scala, Natalie Michele

    With deregulation, utilities in the power sector face a much more urgent imperative to emphasize cost efficiencies as compared to the days of regulation. One major opportunity for cost savings is through reductions in spare parts inventories. Most utilities are accustomed to carrying large volumes of expensive, relatively slow-moving parts because of a high degree of risk-averseness. This attitude towards risk is rooted in the days of regulation. Under regulation, companies recovered capital inventory costs by incorporating them into the base rate charged to their customers. In a deregulated environment, cost recovery is no longer guaranteed. Companies must therefore reexamine their risk profile and develop policies for spare parts inventory that are appropriate for a competitive business environment. This research studies the spare parts inventory management problem in the context of electric utilities, with a focus on nuclear power. It addresses three issues related to this problem: criticality, risk, and policy. With respect to criticality and risk, a methodology is presented that incorporates the use of influence diagrams and the Analytic Hierarchy Process (AHP). A new method is developed for group aggregation in the AHP when Saaty and Vargas' (2007) dispersion test fails and decision makers are unwilling or unable to revise their judgments. With respect to policy, a quantitative model that ranks the importance of keeping a part in inventory and recommends a corresponding stocking policy through the use of numerical simulation is developed. This methodology and its corresponding models will enable utilities that have transitioned from a regulated to a deregulated environment become more competitive in their operations while maintaining safety and reliability standards. Furthermore, the methodology developed is general enough so that other utility plants, especially those in the nuclear sector, will be able to use this approach. In addition to regulated

    The U.S. Department of Energy's (DOE) Office of Environmental Management (DOE/EM) currently supports an effort to understand and predict the fate of nuclear contaminants and their transport in natural and engineered systems. Geologists, hydrologists, physicists and computer scientists are working together to create models of existing nuclear waste sites, to simulate their behavior and to extrapolate it into the future. We use visualization as an integral part in each step of this process. In the first step, visualization is used to verify model setup and to estimate critical parameters. High-performance computing simulations of contaminant transport produces massive amounts of data, which is then analyzed using visualization software specifically designed for parallel processing of large amounts of structured and unstructured data. Finally, simulation results are validated by comparing simulation results to measured current and historical field data. We describe in this article how visual analysis is used as an integral part of the decision-making process in the planning of ongoing and future treatment options for the contaminated nuclear waste sites. Lessons learned from visually analyzing our large-scale simulation runs will also have an impact on deciding on treatment measures for other contaminated sites.

    Full Text Available AbstractSpleen is the most frequent solid organ to be injured in bluntabdominal trauma. Considering its important role in providingimmunity and preventing infection by a variety of mechanisms,every attempt should be made, if possible, to salvagethe traumatized spleen at any age particularly in children. Afterprimary resuscitation, mandatory requirements for nonoperativemanagement include absence of homodynamic instability,lack of associated major organ injury, admission inthe intensive care unit for high-grade splenic injury and in theward for milder types with close monitoring. About two thirdof the patients would respond to non-operative management.In most patients, failure of non-operative measures usuallyoccur within 12 hours of management. Determinant role ofabdominal sonography or computed tomography, and in selectedcases, diagnostic peritoneal lavage, for appropriate decisioncannot be overemphasized. However, the high status ofclinical judgment would not be replaced by any paraclinicalinvestigations. When operation is unavoidable, if possible,spleen saving procedures (splenorrhaphy or partial splenectomyshould be tried. In case of total splenectomy, autotransplantation,preferably in the omental pouch, may lead toreturn of immunity, at least partially, to prevent or reduce thechance of subsequent infection. Although total splenectomywith autograft is immunologically superior to total splenectomy-only procedure, these patients should also be protectedby vaccination and daily antibiotic for certain period of time.The essential steps for prevention of overwhelming infectionafter total splenectomy are not only immunization and administrationof daily antibiotic (up to 5 years of age or one year inolder children, but include education and information aboutthis dangerous complication. When non-operative managementis successful, the duration of activity restriction (inweeks is almost equal to the grade of splenic injury plus 2.Iran J Med Sci 2010

  20. Stiffness management of sheet metal parts using laser metal deposition

    Tailored blanks are established solutions for the production of load-adapted sheet metal components. In the course of the individualization of production, such semi-finished products are gaining importance. In addition to tailored welded blanks and tailored rolled blanks, patchwork blanks have been developed which allow a local increase in sheet thickness by welding, gluing or soldering patches onto sheet metal blanks. Patchwork blanks, however, have several limitations, on the one hand, the limited freedom of design in the production of patchwork blanks and, on the other hand, the fact that there is no optimum material bonding with the substrate. The increasing production of derivative and special vehicles on the basis of standard vehicles, prototype production and the functionalization of components require solutions with which semi-finished products and sheet metal components can be provided flexibly with local thickenings or functional elements with a firm metallurgical bond to the substrate. An alternative to tailored and patchwork blanks is, therefore, a free-form reinforcement applied by additive manufacturing via laser metal deposition (LMD). By combining metal forming and additive manufacturing, stiffness can be adapted to the loads based on standard components in a material-efficient manner and without the need to redesign the forming tools. This paper details a study of the potential of stiffness management by LMD using a demonstrator part. Sizing optimization is performed and part distortion is taken into account to find an optimal design for the cladding. A maximum stiffness increase of 167% is feasible with only 4.7% additional mass. Avoiding part distortion leads to a pareto-optimal design which achieves 95% more stiffness with 6% added mass.

  1. Managing the effects of aging and reliability improvement

    1987-01-01

    Over recent years the electric power generating community has acknowledged the importance of the aging process on plant safety and availability. To cope with time-dependent degradation phenomenon that can affect active as well as passive components and lead to unacceptable, unanticipated failures requires research into the mechanisms of the aging process, advances in productive methods for assessing the aging impact on risk and availability, and a better understanding of power plant operations so that strategies for defending against this pervasive stress can be developed. This paper discusses current research advances and presents a framework to aid in the systematic integration of these three needs. As such it is anchored to research being conducted at Brookhaven National Laboratory in the areas of plant aging, life extension, reliability, performance indication, and risk assessment. The current question facing the industry can be simply stated. ''How can an acceptable level of safety and availability be maintained throughout the operational life of a nuclear power plant?'' The complexity of this question indicates that managing aging effects must be a continuous, coordinated process integrated with day-to-day tactical plant operation decisions. This implies that aging and reliability programs must be systemic properties of an organization's management, and that research into aging technology must be closely linked

  2. Optimized maintenance concept of safety relevant valves related to ageing management features in nuclear power plants

    2007-01-01

    This paper presents the existing concept in E.ON Kernkraft and its sound application to ageing management issues by focussing on group 2 components such as safety relevant valves. It is demonstrated how the maintenance concept of safety relevant valves is supported by a valve diagnostic system accompanied by an applied procedure to assess the measured results with respect to the required functionality and ageing phenomena. Furthermore this concept has been developed to optimize the existing preventive maintenance of the safety relevant valves by implementing condition oriented aspects derived from the diagnostic results. The main issue of this maintenance concept is to demonstrate the high level of the secured function, reliability and performance of the safety relevant valves within an integrated ageing management. Additionally it offers improvements of all preventive maintenance issues as maintenance periods and the component related volume, spare parts management and costs. (author)

    Disorders in bone and calcium metabolism associated with aging are based on secondary hyperparathyroidism due to impaired intestinal calcium absorption caused by insufficient vitamin D actions and augmented bone resorption due to sex hormone deficiency. Both of them are involved in the development of osteoporosis that increases risk of fractures. Therefore, the most important thing for management of disorders in bone and calcium metabolism associated with aging is to prevent fractures with appropriate drugs for osteoporosis.

    Disaster management is a multidisciplinary field, which requires a general coordination approach as well as specialist approaches. Science and Technology system of a country allows to create policies and execution of technical inputs required which provide services for the specific types of disasters management. Land administration and management agencies, as the administrative and management bodies, focus more on the coordination of designated tasks to various agencies responsible for their dedicated roles. They get help from Scientific and technical inputs & policies which require to be implemented in a professional manner. The paper provides an example of such integration from India where these two systems complement each other with their dedicated services. Delhi, the Capital of India, has such a disaster management system which has lot of technical departments of government which are mandated to provide their services as Emergency Service Functionaries. Thus, it is shown that disaster management is a job which is an integral part of Science & Technology system of a country while being implemented primarily with the help of land administration and management agencies. It is required that new policies or mandates for the Science and technology organizations of government should give a primary space to disaster management

    2009-09-01

    To investigate workplace cultures in the acquisition of computer usage skills by mature age workers. Data were gathered through focus groups conducted at job network centres in the Greater Brisbane metropolitan region. Participants who took part were a mixture of workers and job-seekers. The results suggest that mature age workers can be exposed to inappropriate computer training practices and age-insensitive attitudes towards those with low base computer skills. There is a need for managers to be observant of ageist attitudes in the work place and to develop age-sensitive strategies to help mature age workers learn computer usage skills. Mature age workers also need to develop skills in ways which are practical and meaningful to their work.

    Full text: Karachi Nuclear power Plant (KANUPP), a 137 MWe CANDU plant, was built on a turn-key basis by the Canadian General Electric (CGE) in the late sixties. The plant with a design life of thirty years went into commercial operation in October, 1972. After nearly three decades of operation, KANUPP like all other plants has faced the problem of equipment ageing and obsolescence. KANUPP has been striving hard to combat these problems with the assistance from IAEA, COG and WANO. During early eighties IAEA expert missions were called at KANUPP on various safety issues and on their recommendations various projects such as Safe Operation of KANUPP, Technical Upgradation Project, Balancing, Modernization and Rehabilitation project were initiated to combat equipment ageing and obsolescence. KANUPP has made substantial progress in the implementation of the tasks under these projects and the operating life of the plant is expected to be extended by 15 years. Three IAEA expert missions were invited at KANUPP during 1999-2000 to carry out assessment of the ongoing activities related to plant ageing management. On the basis of their recommendations an ageing Management Programme has been formally established at KANUPP to manage age-related degradation of plant systems, structures and components important to safety and to ensure that the required safety functions are available for the extended life of the plant. Being close to completion of its nominal design life in October 2002, KANUPP has already applied to Pakistan Nuclear Regulatory Authority for renewal of operating license. This paper briefly describes the activities related to ageing management of KANUPP to fulfil the requirement for its continued operation beyond its design life. (author)

    A coordinated, multidisciplinary approach to care is essential for optimum management of the primary manifestations and secondary complications of Duchenne muscular dystrophy (DMD). Contemporary care has been shaped by the availability of more sensitive diagnostic techniques and the earlier use of therapeutic interventions, which have the potential to improve patients’ duration and quality of life. In part 2 of this update of the DMD care considerations, we present the latest recommendations for respiratory, cardiac, bone health and osteoporosis, and orthopaedic and surgical management for boys and men with DMD. Additionally, we provide guidance on cardiac management for female carriers of a disease-causing mutation. The new care considerations acknowledge the effects of long-term glucocorticoid use on the natural history of DMD, and the need for care guidance across the lifespan as patients live longer. The management of DMD looks set to change substantially as new genetic and molecular therapies become available. PMID:29395990

    2015-01-01

    Case management directors are in a dynamic position to affect the transition of care for patients across the continuum, work with all levels of providers, and support the financial well-being of a hospital. Most importantly, they can drive good patient outcomes. Although the position is critical on many different levels, there is little to help guide a new director in attending to all the "moving parts" of such a complex role. The purpose of this two-part article is to provide case management directors, particularly new ones, with a framework for understanding and fulfilling their role.We have divided the guide into seven tracks of responsibility. Part 1 discusses the first four tracks: (1) staffing and human resources, (2) compliance and accreditation, (3) discharge planning, and (4) utilization review and revenue cycle. Part 2 addresses (5) internal departmental relationships (organizational), (6) external relationships (Community agency), and (7) quality and program outcomes. The information is most meaningful to those case management directors who work in either stand-alone hospitals or integrated health systems, and have frontline case managers reporting to them. Case management directors would benefit from further research and documentation of "best practices" related to their role, particularly in the areas of leadership and management. New directors would benefit from mentoring and networking with one another. As new regulations and models of care bring increased emphasis and focus to transitions of care, the role of the case management director continues to evolve, growing in importance and complexity. The growing financial impact of readmissions also brings added scrutiny and increased pressure to get the transitions of care right the first time.To operate most effectively, case management directors must understand the full range of their responsibilities and impact. They must find opportunities for themselves and their departments to learn and stay

    Approximately 800 thousand patients require mechanical ventilation in the United States annually with an in-hospital mortality rate of over 30%. The majority of patients requiring mechanical ventilation are over the age of 65 and advanced age is known to increase the severity of ventilator-induced lung injury (VILI) and in-hospital mortality rates. However, the mechanisms which predispose aging ventilator patients to increased mortality rates are not fully understood. Ventilation with conservative fluid management decreases mortality rates in acute respiratory distress patients, but to date there has been no investigation of the effect of conservative fluid management on VILI and ventilator associated mortality rates. We hypothesized that age-associated increases in susceptibility and incidence of pulmonary edema strongly promote age-related increases in ventilator associated mortality. 2month old and 20month old male C57BL6 mice were mechanically ventilated with either high tidal volume (HVT) or low tidal volume (LVT) for up to 4h with either liberal or conservative fluid support. During ventilation, lung compliance, total lung capacity, and hysteresis curves were quantified. Following ventilation, bronchoalveolar lavage fluid was analyzed for total protein content and inflammatory cell infiltration. Wet to dry ratios were used to directly measure edema in excised lungs. Lung histology was performed to quantify alveolar barrier damage/destruction. Age matched non-ventilated mice were used as controls. At 4h, both advanced age and HVT ventilation significantly increased markers of inflammation and injury, degraded pulmonary mechanics, and decreased survival rates. Conservative fluid support significantly diminished pulmonary edema and improved pulmonary mechanics by 1h in advanced age HVT subjects. In 4h ventilations, conservative fluid support significantly diminished pulmonary edema, improved lung mechanics, and resulted in significantly lower mortality rates in

    2009-01-01

    This paper presents EDF practice about concrete structure ageing management, from the materials analysis to the formal procedure which allows EDF to increase 900 MWe NPP lifetime until 40 years. This practice is based on a methodology which identifies every ageing mechanism, then both plants feedback and state of the art are screened and conclusions are drawn up and taken into account into an 'ageing analysis data sheet'. That leads to a collection of 57 data sheets: if the data sheet conclusion is not clear enough, then a more detailed report is launched. This ageing management detailed report gathers every theoretical knowledge and monitoring data; its objective is to propose a solution for ageing management: this solution can include more inspections or specific research development. After a first practise on the 34 French 900 MWe PWR units, only 2 generic ageing management detailed reports have been needed for the civil engineering part: one about reactor building containment which focuses on two mechanisms: steel liner corrosion and pre-stress losses, and one about other structures which focuses on Alkali-Aggregate Reaction (AAR).

This paper focuses on identifying the major trends and strategies concerning talent management programs and development of digital skills for employees and managers. The study reveals that in an open talent economy, employer brand is very important in recruiting and retention of high potential employees and must be focused on learning & leadership development, mobility, rewards and competency systems. At present, in order to obtain a business value, one of the major challenges that HR needs to face is the development of digital skills for managers and employees.

  19. Feasibility Criteria for Interval Management Operations as Part of Arrival Management Operations

    Levitt, Ian M.; Weitz, Lesley A.; Barmore, Bryan E.; Castle, Michael W.

    2014-01-01

    Interval Management (IM) is a future airborne spacing concept that aims to provide more precise inter-aircraft spacing to yield throughput improvements and greater use of fuel efficient trajectories for arrival and approach operations. To participate in an IM operation, an aircraft must be equipped with avionics that provide speeds to achieve and maintain an assigned spacing interval relative to another aircraft. It is not expected that all aircraft will be equipped with the necessary avionics, but rather that IM fits into a larger arrival management concept developed to support the broader mixed-equipage environment. Arrival management concepts are comprised of three parts: a ground-based sequencing and scheduling function to develop an overall arrival strategy, ground-based tools to support the management of aircraft to that schedule, and the IM tools necessary for the IM operation (i.e., ground-based set-up, initiation, and monitoring, and the flight-deck tools to conduct the IM operation). The Federal Aviation Administration is deploying a near-term ground-automation system to support metering operations in the National Airspace System, which falls within the first two components of the arrival management concept. This paper develops a methodology for determining the required delivery precision at controlled meter points for aircraft that are being managed to a schedule and aircraft being managed to a relative spacing interval in order to achieve desired flow rates and adequate separation at the meter points.

  20. Spare part management of an electricity distribution network

    Electricity distribution companies are required to improve their operational cost effectiveness. The storage systems of the companies have traditionally been based on the 'adequate' number of stores with plenty of different components. Therefore, they are potential objects for cost reduction. The effective operation of spare part management of an electricity distribution network requires that the spare components can be delivered at the fault site quickly in order to avoid excessive outage costs. In a fault situation the stores form a net structure. Currently the rural electricity distribution companies lack suitable methods for designing a spare part storage system. This thesis presents a suitable method for the designing problem. The models assume that faults of a distribution network are stochastic. Therefore, they are best suited for component types installed in large quantities. Improved methods for defining the outage, material and total costs for perpetual order quantity and periodic order-up-to-level storage control systems are described. The method for determining the control parameters of the stores is also presented and ways for finding the necessary initial parameter values are introduced. The developed method is tested in Haemeen Saehko Oy (HSOY). The results of the calculations are given. The key findings are: Small differences in the designing results can increase costs remarkably. For example, in HSOY too low stock levels can result in even eight folds higher outage costs than in the proper design. The best number of stores is not the same for all component types. For example, in HSOY the best number of stores is seven for the 50 kVA transformers and one for the 315 kVA transformers in a summer. If the stock levels are increased the protection against the demand variations is the better the shorter the duration of the review period and/or the replenishment lead time is. (orig.)

    Life extension for nuclear power plants has been studied in the USA for the last six years, largely supported by EPRI, DOE and the USNRC. Though there are diverse opinions for the strategies and priorities of life extension and aging management, one common conclusion has been formulated regarding the need of current maintenance programs having to focus on aging and degradation management. Such program, called 'Maintenance Effectiveness Evaluation and Enhancement' or M3E for short, has been developed to assist plant operators to upgrade and enhance existing programs by integrating aging/degradation management activities for important or critical equipment and components. The key elements of the M3E program consist of the definition and selection of the critical components or commodities to be included in the scope, the survey/inventory of the current programs and their respective action steps, frequencies, corrective measures and extent of coverage, the component/commodity degradation mechanism, sites and severity, safety functions and service environments and lastly, the correlation of degradation/aging with the individual maintenance activities. The degree of correlation provides a measure of effectiveness and the opportunity to identify/specify needed enhancements, abandonment or generation of new maintenance activities. Implementation of the activities can then be prioritized at the option of the plant staff. (author)

    The gynecologist's role in the management of rheumatic patients is complex: it includes the prevention of damage caused by drugs, the counseling about contraception to avoid pregnancy while taking teratogen drugs, the scheduling of pregnancy during the quiescent phase of the specific disease, the replacement of teratogen drugs and a competent management of the pregnancy. The task is carried out as part of a multidisciplinary team with a focus on the differential diagnosis between specific complications of pregnancy and the complications of the rheumatic disease. This is the right way to allow a conscious reproduction, with reduced risks and acceptable maternal-fetal outcomes, to this kind of patients considered at high risk.

  4. Space/age forestry: Implications of planting density and rotation age in SRIC management decisions

    Merriam, R.A.; Phillips, V.D.; Liu, W.

    1993-12-31

    Short-rotation intensive-culture (SRIC) of promising tree crops is being evaluated worldwide for the production of methanol, ethanol, and electricity from renewable biomass resources. Planting density and rotation age are fundamental management decisions associated with SRIC energy plantations. Most studies of these variables have been conducted without the benefit of a unifying theory of the effects of growing space and rotation age on individual tree growth and stand level productivity. A modeling procedure based on field trials of Eucalyptus spp. is presented that evaluates the growth potential of a tree in the absence and presence of competition of neighboring trees in a stand. The results of this analysis are useful in clarifying economic implications of different growing space and rotation age decisions that tree plantation managers must make. The procedure is readily applicable to other species under consideration for SRIC plantations at any location.

    Growth hormone deficiency (GHD) is a long-term condition, therefore creating ongoing partnerships with families is a fundamental part of the role of a paediatric endocrine nurse specialist (PENS). Teaching children, young people and their families about GHD and exploring what it means to them and how they can manage their ongoing treatment is central to building positive relationships. Educating children about the management of their growth hormone treatment (GHT) is an ongoing process and professionals must respond to the changing needs for that information children may have as they grow and develop. Long-term relationships with families are strengthened by recognising and respecting the developing expertise of families as they gain confidence and competence to manage GHT. This article is the second of two parts. Part one was published in the February issue of Nursing Children and Young People and covered an overview of growth hormone, causes and clinical presentation of GHD, development and availability of GHT and the role of the PENS in building partnerships with parents. The focus of this article is the education role of the PENS and the importance of providing information that is appropriate to the child or young person's developmental age.

    In the mid-1990s, New Brunswick Power Nuclear implemented a Management System Process Model at the Point Lepreau Generating Station that provides the basic elements of a knowledge management program. As noted by the IAEA, the challenge facing the nuclear industry now is to make improvements in knowledge management in areas that are more difficult to implement. Two of these areas are: increasing the value of existing knowledge, and converting tacit knowledge to explicit knowledge (knowledge acquisition). This paper describes some practical examples of knowledge management improvements in the Point Lepreau heat transport system ageing management program. (author)

    The problem of nuclear reactor ageing is a topic of increasing importance in nuclear safety recent years. Ageing management is usually implemented for reactors maintenance. In the practice, a large number of data and records need to be processed. However, there are few professional software applications that aid reactor ageing management, especially for research reactors. This paper introduces the design of a new web-based management information system (MIS), named the Shielding Experimental Reactor Ageing Management Information System (SERAMIS). It is an auxiliary means that helps to collect data, keep records, and retrieve information for a research reactor ageing management. The Java2 Enterprise Edition (J2EE) and network database techniques, such as three-tiered model, Model-View-Controller architecture, transaction-oriented operations, and JavaScript techniques, are used in the development of this system. The functionalities of the application cover periodic safety review (PSR), regulatory references, data inspection, and SSCs classification according to ageing management methodology. Data and examples are presented to demonstrate the functionalities. For future work, techniques of data mining will be employed to support decision-making.

    Bone age assessment (BAA) is a task performed on radiographs by the pediatricians in hospitals to predict the final adult height, to diagnose growth disorders by monitoring skeletal development. For building an automatic bone age assessment system the step in routine is to do image pre-processing of the bone X-rays so that features row can be constructed. In this research paper, an enhanced point distribution algorithm using contours has been implemented for segmenting bone parts as per well-established procedure of bone age assessment that would be helpful in building feature row and later on; it would be helpful in construction of automatic bone age assessment system. Implementation of the segmentation algorithm shows high degree of accuracy in terms of recall and precision in segmenting bone parts from left hand X-Rays.

  11. Managing the Social Determinants of Health: Part I: Fundamental Knowledge for Professional Case Management.

    Fink-Samnick, Ellen

    PRIMARY PRACTICE SETTING(S):: Applicable to health and behavioral health settings, wherever case management is practiced. The SDH pose major challenges to the health care workforce in terms of effective resource provision, health and behavioral health treatment planning plus adherence, and overall coordination of care. Obstacles and variances to needed interventions easily lead to less than optimal outcomes for case managers and their health care organizations. Possessing sound knowledge and clear understanding of each SDH, the historical perspectives, main theories, and integral dynamics, as well as creative resource solutions, all support a higher level of intentional and effective professional case management practice. Those persons and communities impacted most by the SDH comprise every case management practice setting. These clients can be among the most vulnerable and disenfranchised members of society, which can easily engender biases on the part of the interprofessional workforce. They are also among the costliest to care for with 50% of costs for only 5% of the population. Critical attention to knowledge about managing the SDH leverages and informs case management practice, evolves more effective programming, and enhances operational outcomes across practice settings.

    Development of an aging management plan (AMP) is a crucial contributor to maintaining the reactor safety and controlling the risk of degradation of the concrete reactor building of a nuclear power plant. The design, operation and utilization of a research reactor (RR) fundamentally differ from those of power reactors. The AMP should nonetheless be present on account of radioactive materials and radiation risks involved. This is mainly because the RR is deemed to be used as an experiment itself or to conduct separate experiments during its operation. The AMP aims to determine the requisites for specific structural concrete components of the reactor building that entail regular inspections and maintenance to ensure safe and reliable operation of the plant. The safety of a RR necessitates the provision which is made in its design to facilitate aging management. Aging management of RR's structures is one of the vital factors to safety, to ensure continued adequacy of the safety level, reliable operation of the reactor, and compliance with the operational limits and conditions.Moreover, engineering systems should be qualified to meet the functional requirements for which they were designed with aging and environmental conditions for all situations and at all times taken into account. This study aims to present an integrated methodology for the application of an AMP for the concrete of the reactor building of a typical RR. For the purpose of safety analysis, geometry and ambient conditions were taken from a 5 MW pool-type, light-water moderated, heterogeneous, solid fuel RR in which the water is also used for cooling and shielding (Fig. 1). The reactor core is immersed in either section of a two-section concrete pool filled with water. This paper makes available background information regarding the document and the strategy developed to manage potential degradation of the reactor building concrete as well as specific programs and preventive and corrective

    Crook, B.

    2014-01-01

    In an ageing nuclear power station there are many challenges associated with implementing and refining an asset management program. Ageing nuclear power stations are faced with the formidable task of replacing and refurbishing major Structures, Systems, and Components (SSCs) in a managed and cost-effective way. This paper provides a brief background on equipment reliability and asset management, covers Bruce Power's methodology for implementing this complex and all-encompassing program, and describes one of the key challenges faced by Bruce Power and the industry. The effective scoping and identification of critical components is an on-going challenge which can affect the integrity of many processes built upon it. This is a fundamental building block to nearly all processes at Bruce Power and one that is at the centre of many improvement initiatives and projects. The consequences from lacking this baseline data, or worse relying upon incorrect data, can permeate the asset management process and hinder the organization's ability to assess risk properly and take the necessary steps to mitigate this risk in the short and long term.

  16. Age Management and Sustainable Careers for the Improvement of the Quality of Ageing at Work.

    Science.gov (United States)

    Marcaletti, Francesco

    2014-01-01

    Prolonging working careers by increasing the statutory age for retirement has become compulsory in most Western societies in order to tackle the shrinking of the labour force, preserve economic productivity, foster knowledge transfer and reduce the risks of financial imbalances in social security systems. This imperative currently results in working careers that already exceed 40 years and come to an end after the age of 65 (e.g. in Italy). Over the next few decades, both career length and retirement age are expected to rise. Thus, creating more inclusive workplaces by increasing their quality is the precondition of a win-win situation for both employers and employees, regardless of age. A request for support in the development of sustainable careers from both private and public labour organisations has led to innovating the mainstream methodologies and research tools in the field of age management. Based on the key elements of the mainstream "work ability concept" - i.e. health, competencies, motivation and work organisation - the Quality of Ageing at Work questionnaire (QAW-q), developed by a team from the WWELL Research Centre, broadens its perspective by surveying elements bridging intra-organisational dimensions and which affect employees' conditions and external socio-institutional constraints: i.e. work-life balance, economic stability, professional identity and relationships in the workplace. The QAW-q is designed to analyse the influence of the different meanings of age (chronological age, seniority within the company and in the labour market) and correlate them with the different dimensions at individual and organisational levels; all these dimensions are weighted by the effect exerted by the passage of time. The results of the QAW-q survey, taken by employees of both private and public companies, serve as a basis for the implementation of measures addressing all the relevant dimensions of the human resource management cycle.

    The second research reactor of Egypt, ETRR-II, is an open pool type multi-purpose reactor of 22 MW that has been in operation since 1998. The main purposes of ETRR-II are the production of radioisotopes, personnel training, research and development. Ageing management of ETRR-II is based on the maintenance programme. This programme was planned to have a proactive maintenance strategy that mainly depends on adequate preventive and predictive maintenance. Screening of SSCs is based on safety classes, needs and quality levels. The operation condition and maintenance history are the basis to assess the level of degradation. The ultimate aim of the maintenance team is to perform adequate maintenance work only when it is really necessary. The objectives of the ageing management based maintenance are to maintain and improve equipment availability, confirm compliance with operational limits and conditions, and detect and correct any abnormal condition that might affect reactor safety. The programme also helps to detect trends in ageing so that a plan for mitigating ageing effects can be prepared and implemented. Reactor service conditions are monitored through many parameters and conditions such as conductivity and pH of coolant water, water radiochemical analysis, thermal and hydraulic parameters, a leak detection system, corrosion rate of piping, vibration level of rotating equipment and control rod drop time.

    Electricite de France is now operating 58 PWR nuclear power plants that produce 75% of electricity in France. Besides maintaining safety and availability on a routine basis, it is outmost important to protect the investment. That is the reason why EDF is devoting important resources to implement ageing management concern as an integral part of operation and maintenance programs (for example through appropriate data collection and analysis, specific repair and replacement projects and important anticipation efforts, taking in account the high level of standardisation of the units). A particular organisation has been set up to continuously observe and analyse all activities so as to make sure that ageing concern is correctly taken in account in strategies and that no decisions are susceptible to impair plant lifetime. This 'lifetime program' is paying attention to technical issues associated with main components but is also dealing with issues related to economics and industry situation. (orig.)

    1989-01-01

    The Nuclear Regulatory Commission's Office of Nuclear Regulatory Research is sponsoring this effort to study maintenance as it relates to aging, under the Nuclear Plant Aging Research (NPAR). Maintenance is the primary means of combating and correcting the effects of aging degradation at nuclear power plants. Maintenance effectiveness directly affects the safety of nuclear power plants. Several recent plant events have shown that improper maintenance or a lack of maintenance can be a significant contributory cause of plant incidents (e.g., transients at Rancho Seco and Davis Besse, and the Salem anticipated transient without scram event). In these, and other events, safety related plant equipment functions have been impaired by poor maintenance practices or a lack of maintenance on the specific equipment or in ancillary equipment that affects the ability of the safety related equipment to function. In some cases, the ancillary equipment has been nonsafety-related equipment, or balance-of-plant equipment that has not received adequate maintenance attention. In addition to the potential for causing safety significant plant transients, poor or lacking maintenance may allow the licensing basis of the plant to be eroded without detection. In some cases, time-related aging degradation of equipment that has not been detected, corrected or managed by the maintenance program has been a significant contributory factor. The NPAR program has developed significant information on aging degradation, detection, mitigation, and correction practices for safety-significant structures, systems and components that can be factored into maintenance programs and their effectiveness

    Importance Human immunodeficiency virus (HIV)-positive patients treated with antiretroviral therapy now have increased life expectancy and develop chronic illnesses that are often seen in older HIV-negative patients. Objective To address emerging issues related to aging with HIV. Screening older adults for HIV, diagnosis of concomitant diseases, management of multiple comorbid medical illnesses, social isolation, polypharmacy, and factors associated with end-of-life care are reviewed. Evidence Acquisition Published guidelines and consensus statements were reviewed. PubMed and PsycINFO were searched between January 2000 and February 2013. Articles not appearing in the search that were referenced by reviewed articles were also evaluated. Findings The population of older HIV-positive patients is rapidly expanding. It is estimated that by 2015 one-half of the individuals in the United States with HIV will be older than age 50. Older HIV-infected patients are prone to having similar chronic diseases as their HIV-negative counterparts, as well as illnesses associated with co-infections. Medical treatments associated with these conditions, when added to an antiretroviral regimen, increase risk for polypharmacy. Care of aging HIV-infected patients involves a need to balance a number of concurrent comorbid medical conditions. Conclusions and Relevance HIV is no longer a fatal disease. Management of multiple comorbid diseases is a common feature associated with longer life expectancy in HIV-positive patients. There is a need to better understand how to optimize the care of these patients. PMID:23549585

    Full Text Available Effective and efficient inventory management is the key to the economic sustainability of capital intensive modern industries. Inventory grows exponentially with complexity and size of the equipment fleet. Substantial amount of capital is required for maintaining an inventory and therefore its optimization is beneficial for smooth operation of the project at minimum cost of inventory. The size and hence the cost of the inventory is influenced by a large no of factors. This makes the optimization problem complex. This work presents a model to solve the problem of optimization of spare parts inventory. The novelty of this study lies with the fact that the developed method could tackle not only the artificial test case but also a real-world industrial problem. Various investigators developed several methods and semi-analytical tools for obtaining optimum solutions for this problem. In this study non-traditional optimization tool namely genetic algorithms GA are utilized. Apart from this Coxs regression analysis is also used to incorporate the effect of some environmental factors on the demand of spares. It shows the efficacy of the applicability of non-traditional optimization tool like GA to solve these problems. This research illustrates the proposed model with the analysis of data taken from a fleet of dumper operated in a large surface coal mine. The optimum time schedules so suggested by this GA-based model are found to be cost effective. A sensitivity analysis is also conducted for this industrial problem. Objective function is developed and the factors like the effect of season and production pressure overloading towards financial year-ending is included in the equations. Statistical analysis of the collected operational and performance data were carried out with the help of Easy-Fit Ver-5.5.The analysis gives the shape and scale parameter of theoretical Weibull distribution.

    2004-01-01

    The deregulation of the power generation industry has resulted in increased competitive pressure and is forcing operators to improve plant operating economy while maintaining high levels of plant safety. A key factor to meet this challenge is to apply a comprehensive plant life management (PLIM) approach which addresses all relevant ageing and degradation mechanisms regarding the safety concept, plant components and documentation, plant personnel, consumables, operations management system and administrative controls. For this reason, Framatome ANP has developed an integrated PLIM concept focussing on the safety concept, plant components and documentation. Representative examples for plant wide analyses are described in the following. The results of the analyses support the plant owner for taking the strategic decisions, involved in plant life extension (PLEX). (orig.)

    Review of technical literature and field experience has identified stress corrosion cracking as one of the major degradation mechanisms for the major light water reactor components. Three of the stress corrosion cracking mechanisms of current concern are (a) primary water stress corrosion cracking (PWSCC) in pressurized water reactors, and (b) intergranular stress corrosion cracking (IGSCC) and (c) irradiation-assisted stress corrosion cracking (IASCC) in boiling water reactors. Effective aging management of stress corrosion cracking mechanisms includes evaluation of interactions between design, materials, stressors, and environment; identification and ranking of susceptible sites; reliable inspection of any damage; assessment of damage rate; mitigation of damage; and repair and replacement using corrosion-resistant materials. Management of PWSCC includes use of lower operating temperatures, reduction in residual tensile stresses, development of reliable inspection techniques, and use of Alloy 690 as replacement material. Management of IGSCC of nozzle and attachment welds includes use of Alloy 82 as weld material, and potential use of hydrogen water chemistry. Management of IASCC also includes potential use of hydrogen water chemistry

  14. Introducing Systematic Aging Management for Interim Storage Facilities in Germany

    International Nuclear Information System (INIS)

    Spieth-Achtnich, Angelika; Schmidt, Gerhard

    2014-01-01

    In Germany twelve at-reactor and three central (away from reactor) dry storage facilities are in operation, where the fuel is stored in combined transport-and-storage casks. The safety of the storage casks and facilities has been approved and is licensed for up to 40 years operating time. If the availability of a final disposal facility for the stored wastes (spent fuel and high-level wastes from reprocessing) will be further delayed the renewal of the licenses can become necessary in future. Since 2001 Germany had a regulatory guideline for at-reactor dry interim storage of spent fuel. In this guideline some elements of ageing were implemented, but no systematic approach was made for a state-of-the-art ageing management. Currently the guideline is updated to include all kind of storage facilities (central storages as well) and all kinds of high level waste (also waste from reprocessing). Draft versions of the update are under discussion. In these drafts a systematic ageing management is seen as an instrument to upgrade the available technical knowledge base for possible later regulatory decisions, should it be necessary to prolong storage periods to beyond the currently approved limits. It is further recognized as an instrument to prevent from possible and currently unrecognized ageing mechanisms. The generation of information on ageing can be an important basis for the necessary safety-relevant verifications for long term storage. For the first time, the demands for a systematic monitoring of ageing processes for all safety-related components of the storage system are described. In addition, for inaccessible container components such as the seal system, the neutron shielding, the baskets and the waste inventory, the development of a monitoring program is recommended. The working draft to the revised guideline also contains recommendations on non-technical ageing issues such as the long-term preservation of knowledge, long term personnel planning and long term

Health professionals should take these into consideration when managing dermatological problems in elderly patients. Accordingly, current research is investigating the dermatological problems associated with the loss of cutaneous function with age. As cell renewal slows, the physical and chemical barrier function declines, cutaneous permeability increases, and the skin becomes increasingly vulnerable to external factors. In geriatric dermatology, the consequences of cutaneous aging lead to xerosis, skin folding, moisture-associated skin damage, and impaired wound healing. These problems pose significant challenges for both the elderly and their carers. Most often, nurses manage skin care in the elderly. However, until recently, little attention has been paid to developing appropriate, evidence-based, skincare protocols. The objective of this paper is to highlight common clinical problems with aging skin and provide some appropriate advice on cosmetic protocols for managing them. A review of the

    2013-01-01

    Predictive and preventive maintenance technologies are increasingly of importance for the long term operation (LTO) of Light Water Reactor (LWR) plants. In order for the realization LTO to be successful, it is essential that aging degradation phenomena should be properly managed by using adequate maintenance programs based on foreseeing the aging phenomena and evaluating their rates of development, where Nuclear Power Plants can be continued to operate beyond the original design life depending upon the regulatory authority rules. In combination with Periodic Safety Review (PSR) and adequate maintenance program, a plant life can be extended to 60 years or more. Plant Life Management (PLiM) is based upon various maintenance program as well as systematic safety review updated based upon the state of the art of science and technology. One of the potential life time limiting issue would be materials ageing degradation and therefore an extensive efforts have been paid world-widely. In 2007, NISA launched a national program on Enhanced Ageing Management Program and 4 nationwide clusters were formed to carry out the national program where materials ageing degradation was one of the major topics. In addition to these degradation modes, one important activities in this program is proactive materials degradation management directed by the author which is a kind of the extension program of NRC PMDA program based upon more fundamental approach by a systematic elicitation by the experts nominated from all over the world. NISA program can be divided into two phases, one is from fiscal years (FY) 2006 - 2010 and the other FY 2011. Later phase is focusing more on System Safety due to Fukushima NPP accident. The main objectives of the Phase I is to evaluate potential and complex degradation phenomena and their mechanisms in order to identify future risks of component aging in nuclear power plants. The following items are of particular concern in this phase: (a) investigation of

    Although the nuclear plant was designed for the purpose of the 30-year life the early stages of construction, it also already has the plant abolished by passing in 30 years. There is a plant under operation and a plant that is employed variously, extends the original life and continues operation now, and the plant that is going to be abolished politically is before a life. By using a nuclear plant for a long period of time, damage. by the influence of irradiation, wear of slipping, corrosion, etc. appears. When this degradation is left, the serious accident is caused. In this lecture, refer to Assessment and management of ageing of major nuclear power plant components important to safety, Oct. 1999 of IAEA.

    One of the key factors, which are negatively affecting the operational safety of nuclear power plants, is the process of ageing. The need for the elimination of these ageing related damages is self-evident and naturally of the highest priority, to preserve the operational safety and reliability. Keeping in mind the safety and reliability of operated devices, and on the other hand the effort to maximize the device utilization, it is recommended to introduce and implement the programs for the monitoring and management of ageing of individual systems, structures and components (SSC). These shall ensure the possibility to monitor and evaluate the effects of degeneration processes on the selected SSC's , to monitor the trends in the parameters measured and ensure the adoption of appropriate corrective actions in real time. The number of nuclear reactors, which are exceeding the originally assumed operational longevity, as defined by original project documentation, is rapidly increasing. It is to no surprise that the demand for their extended operational longevity is increasing hand in hand with the strengthening safety and regulatory requirements worldwide. Each nuclear power plant consists of, among others, kilometers and miles of electric and I and C cables. Their task is irreplaceable, and their excellent condition is vital for the safety and reliability of seamless power plant operation. Thus it is critical and essential to recognize and monitor the real performance of the cables, and to implement programs, which monitor their actual condition. A successful implementation of ageing programs is a cornerstone of safe power plant operations in a long run. The focus of this presented paper is the defined approach, stated goals, and the results achieved in the area of cable ageing and longevity monitoring in the environment of Slovak nuclear power plants.

  7. Widespread protein aggregation as an inherent part of aging in C. elegans.

    Directory of Open Access Journals (Sweden)

    Della C David

    Full Text Available Aberrant protein aggregation is a hallmark of many age-related diseases, yet little is known about whether proteins aggregate with age in a non-disease setting. Using a systematic proteomics approach, we identified several hundred proteins that become more insoluble with age in the multicellular organism Caenorhabditis elegans. These proteins are predicted to be significantly enriched in beta-sheets, which promote disease protein aggregation. Strikingly, these insoluble proteins are highly over-represented in aggregates found in human neurodegeneration. We examined several of these proteins in vivo and confirmed their propensity to aggregate with age. Different proteins aggregated in different tissues and cellular compartments. Protein insolubility and aggregation were significantly delayed or even halted by reduced insulin/IGF-1-signaling, which also slows aging. We found a significant overlap between proteins that become insoluble and proteins that influence lifespan and/or polyglutamine-repeat aggregation. Moreover, overexpressing one aggregating protein enhanced polyglutamine-repeat pathology. Together our findings indicate that widespread protein insolubility and aggregation is an inherent part of aging and that it may influence both lifespan and neurodegenerative disease.

    This paper proposes a new approach to Ageing Probabilistic Safety Assessment (APSA) modelling, which is intended to be used to support risk-informed decisions on the effectiveness of maintenance management programs and technical specification requirements of critical equipment of Nuclear Power Plants (NPP) within the framework of the Risk Informed Decision Making according to R.G. 1.174 principles. This approach focuses on the incorporation of not only equipment ageing but also effectiveness of maintenance and efficiency of surveillance testing explicitly into APSA models and data. This methodology is applied to a motor-operated valve of the auxiliary feed water system (AFWS) of a PWR. This simple example of application focuses on a critical safety-related equipment of a NPP in order to evaluate the risk impact of considering different approaches to APSA and the combined effect of equipment ageing and maintenance and testing alternatives along NPP design life. The risk impact of several alternatives in maintenance strategy is discussed

With the advent of new technologies, the physician has the opportunity of addressing these changes with the utilization of dermal fillers. Hyaluronic acid (HA dermal fillers are the most popular, non-permanent injectable materials available to physicians today for the correction of soft tissue defects of the face. This material provides an effective, non invasive, non surgical alternative for correction of the contour defects of the face due to its enormous ability to bind water and easiness of implantation. HA dermal fillers are safe and effective. The baby-boomer generation, and their desire of turning back the clock while enjoying an active lifestyle, has expanded the popularity of these fillers. In the US, there are currently eight HA dermal fillers approved for commercialization by the Food and Drug Administration (FDA. This article reviews the innate properties of FDA-approved HA fillers and provides an insight on future HA products and their utilization for the management of the aging face.Keywords: hyaluronic acid, aging face, dermal filler, wrinkles, Restylane, Perlane, Juvéderm

    Life Cycle Management is a structured process to manage equipment aging and long-term equipment reliability for nuclear plant Systems, Structures and Components (SSCs). The process enables the identification of effective repair, replace, inspect, test and maintenance activities and the optimal timing of the activities to maximize the economic value to the nuclear plant. This paper will provide an overview of the process and some of the tools that can be used to implement the process for the SSCs deemed critical to plant safety and performance objectives. As nuclear plants strive to reduce costs, extend life and maximize revenue, the LCM process and the supporting tools summarized in this paper can enable development of a long term, cost efficient plan to manage the aging of the plant SSCs.

    2006-01-01

    Within the scope of PLEX, a systematic and efficient ageing and plant life management system is becoming more and more important to ensure a safe and economical power plant operation in spite of continuous plant ageing. For the methodical implementation of PLIM and PLEX strategies, AREVA NP has developed the software tool COMSY. This knowledge-based program integrates degradation analysis tools with an inspection data management system. COMSY provides the capability to establish a program guided technical documentation by utilizing a virtual plant model which includes information regarding thermal hydraulic operation, water chemical conditions and materials applied for mechanical components. It provides the option to perform a plant-wide screening for identifying system areas, which are sensitive for degradation mechanisms typically experienced in nuclear power plants (FAC, corrosion fatigue, IGSCC, Pitting, etc.). If a system area is identified as being susceptible to degradation, a detailed analysis function enables the condition-oriented service life evaluation of vessels and piping systems in order to localize and conservatively quantify the effect of degradation. Based on these forecasts with COMSY, specific strategies can be developed to mitigate the effect of degradation and inspection activities can be focused on degradation sensitive areas. In addition, a risk-informed assessment tool serves to optimize inspection activities in respect to degradation potential and the associated damage consequence. After an in-service inspection is performed for a distinct location, the inspection data is to be evaluated according to generally accepted procedures. For this purpose an integrated inspection data management system module provides standardized, interactively operated evaluation functions. The key inspection results are transmitted as feedback in respect to the as-is condition of the component. Subsequently, all further life evaluations of the associated

    The scope of this work includes the study of all feedwater heaters (from 1 to 6) in their two trains (A and B). In this study the main degradation phenomena that affect them, the operating parameters that can warn of a possible malfunction of the heater and possible strategies inspection, repair and replacement are analyzed. As a result of this study, a higher priority is obtained at a lower state of degradation of the heaters, possibly with a strategy inspection, repair or replacement, for each recharge, until the end of life of the plant. This will be a live program, which must be fed back to the studies of the parameters of operation of the heater during operation and results of the inspection of each recharge. May verify the effectiveness of aging management program using different indicators. (Author)

  1. Approach of British Nuclear Fuels to managing ageing

    International Nuclear Information System (INIS)

    2006-01-01

    The approach taken by BNFL to managing ageing is developed at the design stage and builds upon experience gained through designing, building, operating and decommissioning nuclear facilities since 1947. Much of the current philosophy was developed during the design and construction of the Thermal Oxide Reprocessing Plant (THORP). The process of managing ageing encompasses all the phases of the facility's life; that is, design, operation and decommissioning. Underlying all these phases is the input from the results of research and development and plant inspection activities. Plant ageing is managed by a policy of understanding the degradation mechanisms as far as possible and, from that knowledge, targeting for particular attention plants considered as vulnerable or for which we are uncertain of our understanding of the degradation processes; for example, THORP receipt and storage LWR storage racks have been fabricated from 304L stainless steel. In their storage environment, deionized water, the worst case measured corrosion rate for such steels is 0.03 mm/a. Given that the minimum material thickness used is 20 mm, corrosion over the design life is negligible and therefore there are no prescribed monitoring or maintenance requirements. Plant inspection policy was first developed for THORP, where targeted programmes of inspection are established. Inspection may be limited to visual inspection or may involve quantitative non-destructive testing such as ultrasonics, and in certain areas, such as dissolvers, on-line thickness monitors have been installed to facilitate the process. The programmes are updated as the actual plant operating conditions are better known and understood; therefore, for example, an SSC found to be operating at higher temperatures than originally planned or carrying a higher burden of corrodents may become targeted for inspection, whereas SSCs perceived to be benign may have inspection frequencies reduced. Similar policies are being developed for

    Abnormal uterine bleeding is a common gynecological disease and represents one of the most frequent reasons for hospital admission to a specialist unit, often requiring further surgical treatment. Following the so-called PALM-COEIN system we will attempt to further clarify the surgical treatments available today. The first group (PALM) is characterized by structural lesions, which may be more appropriately treated by means of surgical management. Although hysterectomy remains the definitive and decisive choice, there are many alternative techniques available. These minimally invasive procedures offer the opportunity for a more conservative approach. Precise and accurate counseling facilitates better patient selection, based on the patient's desires, age and disease type, allowing treatment to be individually tailored to each woman.

  3. Aging and lifetime management - A plant-wide concept and examples for realization

    It is of central importance to understand, analyze and manage aging-related phenomena and to apply this information in the systematic utilization and as-necessary extension of the service life of components and systems. 'Aging' in this context is understood to mean the change over time of the service-related characteristics and properties of the following nuclear power plant items: the equipment (mechanical components, structures, electrical and I and C systems); the computer systems (hardware and software) required for plant operation; the plant specifications and documentation. From this it is obvious that a competent strategy for aging and plant life management must cover all key-components relevant for safety and availability of the plant. Besides mechanical components, instrumentation and control devices, and civil engineering structures are to be considered, regarding both aspects, function and integrity. 'Aging and plant life management' encompasses all organizational and technical measures with which aging phenomena are recognized and managed by the plant operator, and which thereby guarantee full utilization of a component or system over its entire service life, or which must be taken at the proper time to extend service life and guarantee long-term plant integrity. An adequate strategy follows for taking measures to avoid detrimental effects on lifetime. Preventive measures can be the change of operation modes to suppress rigid degradation, the change of operating parameters or system engineering methods to optimize the operation of systems and components, and the replacement of aged component parts, components, or systems by new ones, made with an improved design or representing an advanced technique. The strategy is challenging: the improvement of availability by optimizing the outage times and the operation; the increase of safety and reliability; the reduction of man-rem exposure and costs for waste management and amount of waste; the optimized early

    This report describes the effect of different accident management strategies on the onset, development and end of the core-concrete-interaction as well as on the containment integrity for a TMLB'-type sequence in a Pressurized Water Reactor of the type VVER- 1000. Using the computer code MARCH3 the following strategies were investigated: (1) One or more Spray and LP ECC Systems available with and without coolers after 10 hours (2) Inclusion of the reactor pressure vessel testing facility room to the cavity (3) Containment venting (4) External water supply and (5) Different electric power restoration times. The results show that some of these accident management measures will maintain the containment integrity and reduce the source term drastically, others will reduce the source term rate. For some measures final conclusions can only be given after complete source term calculations have been performed. (authors)

  7. [Health management as part of leadership in public administration].

    Science.gov (United States)

    Matyssek, A K

    2012-02-01

    Leadership includes two tasks within public administration: leading employees by creating healthy working conditions and being led by others. The basis of leading others in a healthy way means dealing with oneself in a healthy manner; this includes typical healthy behavior (i.e., physical activity, improved nutrition, not smoking), which allows for recovery by a good work-life balance and a sensitive dealing with one's own limits. Given these conditions of healthy self care, managers are able to act as role models and lead their employees in a healthy manner. Leading in a healthy manner means showing appreciation, being interested in the employees ("caring"), integrating them in decision-making, allowing transparency, improving the working atmosphere, and finally reducing stress and increasing resources. The latter includes social support, which decreases the danger of employees burning out. The article presents the concept of a 2-day training that is designed for managers in order to raise their awareness for duties related to health management in public administration.

    Full Text Available Youth unemployment is currently a stringent problem in many European countries. Most of the time, both the public opinion and the national and European institutions blame the economic crisis, the social conditioning of these youngsters, and point to the failure of the educational systems to provide them with the necessary qualifications needed on the market. There are a few initiatives, such as the Youth Guarantee launched in 2013, led by European public authorities in order to reduce this phenomenon, but these initiatives address solely the professional proficiency of the youngsters. And most authorities perceive them as citizens who need to be trained to fit with the existing working environments. The situation is, in fact, more complex, as todays youngsters are different from the previous generations in terms of the values they share and the basic way they process information. When speaking of the youth, the high unemployment rate due to system imbalance between people training and work fields’ requirements are just one side of the coin. The other side speaks about the impact digital technology has upon young people, favouring the emergence of the so called digital natives, and about the fact that the working environment in itself has to incorporate changes in order to accommodate these youngsters and fully benefit from their capabilities.     As Romanian digital natives come of age, minimizing the mind gap between elder managers and younger employees and candidates becomes an important issue that companies increasingly have to deal with. This article explores the digital natives’ expectations from their managers and from the companies they aim to work for, based upon a survey conducted in four universities in Bucharest. We propose a series of recommendations for managers who work closely with digital natives, in order to improve the work environment and create the premises for better job performance in their teams, possibly reducing

    Fast Breeder Test Reactor is a 40 MWt, sodium cooled, PuC-UC fuelled fast reactor, located at Kalpakkam, India. The reactor went critical in October 85 with Mark I core rated for 10.5 MWt at a peak LHR of 320 W/cm. The reactor core was progressively enlarged and TG was synchronized to the grid in July 97. The present core has 41 fuel subassemblies rated for 15.7 MWt at a peak LHR of 320 W/cm. The reactor has so far been operated for 33000 h and has seen 660 EFPD of operation corresponding to peak LHR of 320 W/cm. The peak burnup reached by the carbide fuel is 127 GWd/t, without any fuel clad failure. The four sodium pumps have been operating satisfactorily for a cumulative time of more than 5,00,000 h. Creep, fatigue and fluence govern the life of the nuclear systems. Because of the reduced power and temperature at which the reactor has so far been operated, there is little ageing of the nuclear systems. The life of the nuclear components is being monitored by periodic surveillance. Periodic assessment of the fluence seen by reactor components is being made. The conventional systems have been in service for the past 19 years. Civil structures are 25 years old. These have been maintained by periodic preventive maintenance and replacement / repair wherever required. This paper details the various ageing management practices in FBTR. (author)

    As, in recent years, many quality assurance (QA) related incidents, such as falsely-certified parts and forged documentation, etc., were reported in association with the supply of structures, systems, components and parts to nuclear power plants, a need for a better management of safety classification system was addressed so that it would be based more on the level of parts . Presently, the Korean nuclear power plants do not develop and apply relevant procedures for safety classifications, but rather the safety classes of parts are determined solely based on the experience of equipment designers. So proposed in this paper is a better management plan for safety equipment classification system with an aim to strengthen the quality management for parts. The plan was developed through the analysis of newly introduced technical criteria to be applied to parts of nuclear power plant.

    The combination of one or several processes of ruins can involve the materials failure of a nuclear power plant. These processes arise from the external agents action such as the pressure, the mechanical efforts, the heat flows and the radiations constitute the whole of the 'actions' of the surrounding medium. The prolongation and the repetition of these effects can involve a deterioration of the machine. In accordance with the decree of February 26, 1974, the PWR operator must be firstly, sure that the system is controlled according to the situations considered in the file of dimensioning and secondly, be able to know anytime the life of the equipment. The physical phenomena which cause the structures ruin are less complex in the PWR than in the SFR. In the SFR, the high temperatures imposed on components for long periods can involve a significant creep. In the course of time, this deformations accelerate the release of fatigue cracks. To consider the creep, the reactor lifespan is correlated at the numbers of thermals transients envisaged initially. To realize the management of aging in Phenix power plant, it is necessary to carry out an individualized monitoring of the structures and not only on the vessel. We must ensure the good state and/or the correct operation of the significant stations for safety which are the control of the reactivity, the movement of control rods, the primary sodium containment and the decay heat removal. For that, we monitor the main vessel, the conical skirt, the IHX and the Core Cover Plug. A profound knowledge of the thermal transients of the past is necessary to carry out an effective assessment. In order to guarantee that any harmful situation is well taken into the management of aging, we monitor permanently certain measurements (primary and secondary pump speed, hot and cold pool temperatures, IHX-main vessel and reactor roof temperatures). We present in the article the scientific method used in the Physics Section. A logical

    Tarapur Atomic Power Station, the longest serving Nuclear Power Plant in the Asian continent has completed 36 years of successful operation and generated more than 70,000 million units of electric power. Built in late sixties, with the state-of-the-art safety features prevailing then, TAPS through the process of evolution has become safer plant due to efforts of upgradation, renovation and refurbishment prompted by the station's operating experience, feed back from overseas reactors, lessons learnt from nuclear incidents, accidents and fresh review of design basis and safety analysis of the plant. All components of a Nuclear power plant experience some degradation with time. The Reactor Pressure Vessels (RPV) designed for 40 effective full power years (EFPY) of operation have operated for less than 20 EFPY and the material condition is assessed to be fit for some more years of service. The condition of the containment and main plant buildings was assessed to be satisfactory. The Ageing Management Programme (AMP) involved identification of key systems, structures and components (SSCs) that may experience degradation due to ageing, and take corrective measures through maintenance, repair and/or replacement. The identified components were classified as major critical components, important systems and other critical components. For each component mode of degradation was identified, ageing assessment was done and action plan was finalized. Replacement of some important equipment like 3 x 50 % capacity Emergency Diesel Generators (EDG) with 3 x 100 % capacity EDG, Salt Service Water (SSW) pumps, Control rod drive (CRD) pumps, Emergency Condenser tube bundles, Station battery has been done on the basis of condition monitoring and to obviate common cause failure and enhance the system reliability. Samples of Safety related cables were subjected to residual life assessment (RLA) and replacement action firmed up on the basis of the RLA findings. Condition survey of Main

    A nuclear power plant is built with a certain design life but by managing the operation of the plant with a well designed in-service inspection, repair and replacement programme of the equipment as required we will be able to extend the operation of the plant well beyond it's design life. This is also economically a paying proposition in view of the astronomical cost of construction of a new plant of equivalent capacity. In view of this, there is a growing trend the world over to study the ageing phenomena, especially in respect of nuclear power plant equipment and system which will contribute towards the continued operation of the nuclear power plants beyond their economic life which is fixed mainly to amortize the investments over a period. Tarapur Atomic Power Station (TAPS) which consists of 2 nos. of Boiling Water Reactor (BWRs) with the presently rated capacity of 160 MWe each has been operating for the past 24 years and is completing its 25th year of service by the year 1994 which was considered as its economic life and the plant depreciation as well as fuel supply agreement were based on this period of 25 years. I will be discussing about the available residual life which is much more than the above (25 years) and the studies we have undertaken in respect of the assessment of this residual life.

    The International Continence Society (ICS) defines overactive bladder (OAB) as an association of symptoms including "urgency, with or without urge incontinence, usually with increased frequency and nocturia". This conditon has been associated with a decrease in quality of life and a higher related risk of overall health condition decrease, and is rising since its prevalence increases with age and the forecast for the world population estimates an increase of those over 65 years old. Aging alone can be considered a major risk factor for developing OAB symptoms that are considered multifactorial and due to body tissue and anatomic changes, lifestyle-associated factors, comorbidities and personal characteristics. The high prevalence of this condition and multiple etiology factors makes of its treatment a challenge-especially in the older population. A major concern over OAB treatment of elderly patients is the risk of cognitive side effects due to the pharmacologic treatment with anticholinergic drugs. First-line treatment for OAB symptoms are the use of pharmacologic therapy with antimuscarinic drugs, which has been proved to be effective in controlling urgency, urge incontinence episodes, incontinence episodes, and nocturia. The impact caused by this condition is significant regarding the economic and human costs associated bringing into attention the need of studying and reviewing this specific population. Conservative Management and Lifestyle Modifications: Behavioral therapy's aims are to reduce urinary frequency and urgency to an accepted level and to increase bladder outlet volume. It consists of actions to teach patients to improve and learn bladder control. Lifestyle modifications are a conjunct of daily activities that can be managed to have the lowest interference on the functioning of the urinary tract. Pharmacologic Therapy: There are various medications with antimuscarinic properties available for the treatment of OAB symptoms. The most commonly used are

Design/methodology/approach: First, this work enumerates the different managerial decisions instances in spare parts management that are present during the life cycle of a physical asset. Second, we analyse how those decision instances could affect the TCO of a physical asset (from the economic point of view). Finally, we propose a conceptual framework for incorporating the spare parts management into a TCO model. Findings: The recent literature lacks discussions on the integration of spare parts management with the Total Costs of Ownership (TCO). Based in an extensive literature revision we can declare that the computation of costs related to spare parts management has been neglected by TCO models. Originality/value: The contribution of this paper is twofold. First, a literature review and identification of a series of spare parts management decision instances and its relationship with TCOs is presented in this paper. Second, a conceptual framework is suggested for linking those decisions instances to a total cost of ownership perspective. Some research questions and future research challenges are presented at the end of this work.

    1977-12-01

    An instrumentation system (Aging Integrator) has been developed to provide more precise control of the heat-treatment process used on uranium-0.75 wt.% titanium alloy material. The Aging Integrator calculates the integral of a predetermined aging function to control the aging period in the heat-treatment process. This control was employed to compensate for discrepancies caused by variations in heatup times, furnace-control fluctuations, and disagreement as to the temperature at which aging actually starts. Although the Aging Integrator hardware has been installed and satisfactorily tested on a production-area furnace, sufficient data to estimate a statistically sound aging integration function will not be available for approximately one year

    2015-04-01

    Full Text Available Aim of study: Exploring the potential effects of various forest management strategies on the ability of forest ecosystems to sequester carbon and produce water has become of great concern among forest researchers. The main purpose of this study is to evaluate the effects of management strategies with different minimum harvesting ages on the amount and monetary worth of carbon, water and timber values. Area of study: The study was performed in the Yalnızçam planning unit located on the northeastern part of Turkey. Material and Methods: A forest management model with linear programming (LP was developed to determine the effects of various minimum harvesting ages. Twenty-four different management strategies were developed to maximize the economic Net Present Value (NPV of timber, water and carbon values in addition to their absolute quantities over time. Amount and NPV of forest values and ending inventory with different minimum harvesting ages were used as performance indicators to assess and thus understand forest dynamics. Main results: Amount and NPV of timber and carbon generally decreased with extended minimum harvesting ages. However, similar trends were not observed for water production values. The results pointed out that the performance of a management strategy depends highly on the development of a management strategy and the initial forest structure aside from the growth rate Research highlights: Minimum harvesting ages affect forest outputs under the same objectives and constraints. Performance of a management strategy highly depends on initial age class structure in addition to the contents of a management strategy.

    2010-01-01

    Although children and infants are likely to be victims in a disaster and are more vulnerable in a disaster than adults, disaster planning and management has often overlooked the specific needs of pediatric patients. We discuss key components of disaster planning and management for pediatric patients including emergency medical services, hospital/facility issues, evacuation centers, family separation/reunification, children with special healthcare needs, mental health issues, and overcrowding/surge capacity. Specific policy recommendations and an appendix with detailed practical information and algorithms are included. The first part of this three part series on pediatric issues in disaster management addresses the emergency medical system from the field to the hospital and surge capacity including the impact of crowding. The second part addresses the appropriate set up and functioning of evacuation centers and family separation and reunification. The third part deals with special patient populations: the special healthcare needs patient and mental health issues.

    1999-01-01

    Complex interpersonal conflicts are inevitable in the high speed, high stakes, pressured work of health care. Poorly managed, conflict saps productivity, erodes trust, and spawns additional disputes. Well managed, conflict can enhance the self-confidence and self-esteem of the parties, build relationships, and engender creative solutions beyond expectations. Just as thoughtful differential diagnosis precedes optimum treatment in the doctor-patient relationship, management of conflict is greatly enhanced when preceded by careful assessment. In the first of two articles, the authors present a diagnostic approach, the Conflict Management Checklist, to increase self-awareness and decrease anxiety around conflict.

    The process and safety system of a nuclear power plant must achieve the reliability/availability target throughout the plant life or for extended plant life. It is therefore necessary to assess the trend of component or system ageing and to take preventive measures so that ageing effect can be counter balanced. In this paper a mathematical model has been established to predict ageing effect and to find out time dependent inspection or test interval to upgrade the system availability. (author). 5 figs

  8. Management Culture as Part of Organizational Culture in the Context of Corporate Social Responsibility Implementation

    Directory of Open Access Journals (Sweden)

    Jolita Vveinhardt

    2017-10-01

    Full Text Available The article is theoretically based on management culture as part of the formal organizational culture, separately reviewing some of its elements. Expert evaluation organization, process and results of the instrument shaped by the authors and meant for qualitative research are briefly presented. The structure of the instrument is detailed by presenting its component parts and explanations. The research was carried out by interviewing the top managers of two big manufacturing company groups consisting of six enterprises. The article presents passages of an interview with the top managers of the six companies, revealing management culture as part of the formal organizational culture expression aiming to implement corporate social responsibility. It should be emphasized that the companies of both groups are preparing to become socially responsible and this results in the timeliness and importance of the research. Structured interviewing method was applied for the research, and the substantive content of the interview included strategy, organizational structure, rules and regulations, technologies, processes, information systems, control and incentive issues. The results of the research show that in both groups of the manufacturing companies management culture and corporate social responsibility, analysing them in terms of formal organizational culture, are perceived in very narrow aspects and their development is not part of the organizations’ strategic goals. The results of the study suggest that the ideas of corporate social responsibility cannot be implemented in a consistent way unless they are integrated into the formal part of organisational culture which plays an instrumental role.

  9. Anesthesia and ventilation strategies in children with asthma: part II - intraoperative management.

    Regli, Adrian; von Ungern-Sternberg, Britta S

    2014-06-01

    As asthma is a frequent disease especially in children, anesthetists are increasingly providing anesthesia for children requiring elective surgery with well controlled asthma but also for those requiring urgent surgery with poorly controlled or undiagnosed asthma. This second part of this two-part review details the medical and ventilatory management throughout the perioperative period in general but also includes the perioperative management of acute bronchospasm and asthma exacerbations in children with asthma. Multiple observational trials assessing perioperative respiratory adverse events in healthy and asthmatic children provide the basis for identifying risk reduction strategies. Mainly, animal experiments and to a small extent clinical data have advanced our understanding of how anesthetic agents effect bronchial smooth muscle tone and blunt reflex bronchoconstriction. Asthma treatment outside anesthesia is well founded on a large body of evidence.Perioperative prevention strategies have increasingly been studied. However, evidence on the perioperative management, including mechanical ventilation strategies of asthmatic children, is still only fair, and further research is required. To minimize the considerable risk of perioperative respiratory adverse events in asthmatic children, perioperative management should be based on two main pillars: the preoperative optimization of asthma treatment (please refer to the first part of this two-part review) and - the focus of this second part of this review - the optimization of anesthesia management in order to optimize lung function and minimize bronchial hyperreactivity in the perioperative period.

    1993-01-01

    This work is carried out under cost-sharing contract with European Atomic Energy Community in the framework of its programme on Management and Storage of Radioactive Wastes. Part 1: PMATCH, A Program to Manage Thermochemical Data, describes the development and use of a computer program, by means of which new thermodynamic data from literature may be referenced to a common frame and thereby become internally consistent with an existing database. The report presents the relevant thermodynamic expressions and their use in the program is discussed. When there is not sufficient thermodynamic data available to describe a species behaviour under all conceivable conditions, the problems arising are thoroughly discussed and the available data is handled by approximating expressions. Part II: The Experimental Validation of Geochemical Computer models are the results of experimental investigations of the equilibria established in aqueous suspensions of mixtures of carbonate minerals (Calcium, magnesium, manganese and europium carbonates) compared with theoretical calculations made by means of the geochemical JENSEN program. The study revealed that the geochemical computer program worked well, and that its database was of sufficient validity. However, it was observed that experimental difficulties could hardly be avoided, when as here a gaseous component took part in the equilibria. Whereas the magnesium and calcium carbonates did not demonstrate mutual solid solubility, this produced abnormal effects when manganese and calcium carbonates were mixed resulting in a diminished solubility of both manganese and calcium. With tracer amounts of europium added to a suspension of calcite in sodium carbonate solutions long term experiments revealed a transition after 1-2 months, whereby the tracer became more strongly adsorbed onto calcite. The transition is interpreted as the nucleation and formation of a surface phase incorporating the 'species' NaEu(Co 3 ) 2

    1991-01-01

    Maintenance Management Support Systems (MMSSs) for nuclear power plants have been developed using component aging estimation methods and decision tree analysis for maintenance planning. The former evaluates actual component reliability through statistical analysis on field maintenance data. The latter provides preventive maintenance (PM) planning guidance using heuristic expert knowledge and estimated reliability parameters. The following aspects have been investigated: (1) A systematic and effective method of managing components/parts design information and field maintenance data (2) A method for estimating component aging based on a statistical analysis of field maintenance data (3) A method for providing PM planning guidance using estimated component reliability/performance parameters and decision tree analysis. Based on these investigations, two MMSSs were developed. One deals with 'general maintenance data', which are common to all component types and are amenable to common data handling. The other system deals with 'specific maintenance data', which are specific to an individual component type. Both systems provide PM planning guidance for PM cycles propriety and the PM work priority. The function of these systems were verified using simulated maintenance data. (author)

  13. Progress in the contemporary management of hemophilia: The new issue of patient aging.

    Mannucci, Pier Mannuccio; Iacobelli, Massimo

    2017-09-01

    The management of inherited coagulation disorders such as hemophilia A and B has witnessed dramatic progresses since the last few decades of the last century. Accordingly, persons with hemophilia (PWH) now enjoy a life expectancy at birth not different from that of males in the general population, at least in high income countries. Nowadays, a substantial proportion of PWH are aging, like their peers in the general population. This outstanding progress is accompanied by problems that are in part similar to those of any old person (multiple concomitant diseases and the resulting intake of multiple drugs other than those specific for hemophilia treatment). In addition, older PWH suffer from the consequences of the comorbidities that developed when their treatment was at the same time poorly available and unsafe. Typical hemophilia comorbidities affect the musculoskeletal system following joint and muscle bleeds, but also the liver and kidney are often impaired due to previous bloodborne infections such as viral hepatitis and HIV. Thus, the comorbidities of hemophilia superimposed on the multimorbidity and polypharmacy associated with aging create peculiar problems in the current management of these patients, that demand the coordinated holistic intervention of internists, geriatricians and clinical pharmacologists in addition to the care traditionally provided by pediatricians and hematologists.

    1992-01-01

    This Phase I Nuclear Plant Aging Research (NPAR) study examines the aging phenomena associated with BWR control and rod drive mechanisms (CRDMs) and assesses the merits of various methods of ''imaging'' this aging. Information for this study was acquired from (1) the results of a special CRDM aging questionnaire distributed to each US BWR utility, (2) a first-of-its-kind workshop held to discuss CRDM aging and maintenance concerns, (3) an analysis of the Nuclear Plant Reliability Data System (NPRDS) failure cases attributed to the control rod drive (CRD) system, and (4) personal information exchange with nuclear industry CRDM maintenance experts. The report documenting the findings of this research, NUREG-5699, will be published this year. Nearly 23% of the NPRDS CRD system component failure reports were attributed to the CRDM. The CRDM components most often requiring replacement due to aging are the Graphitar seals. The predominant causes of aging for these seals are mechanical wear and thermal embrittlement. More than 59% of the NPRDS CRD system failure reports were attributed to components that comprise the hydraulic control unit (HCU). The predominant HCU components experiencing the effects of service wear and aging are value seals, discs, seats, stems, packing, and diaphragms

    Colon cancer is more common in the elderly than in younger and middle-aged people. Cancer clinical trials focus more on younger patients and the management of elderly patients with advanced disease is still unclear. We studied all patients presenting with colon adenocarcinoma metastasis to liver at a community teaching hospital from Dec 2000 through Dec 2007 by a retrospective review of Tumor Registry data and patient chart review with focus on age, clinical management, decision making, and survival. Sixty-seven patients with a median age of 69 and a male to female ratio of 31:36 were identified. The patients with obstructive symptoms and Eastern Cooperative Oncology Group performance status on presentation though varied little by age, smaller proportion of elderly patients underwent resection of the primary bowel tumor in the presence of liver metastases with ten of 16 (63%) aged 80 or greater being managed without surgery. The percentage of patient's preference to physician's preference for patients not undergoing the primary bowel resection increased for older age group. Median survival decreased significantly with age (p management, decision-making autonomy, and survival are apparent in this study, and there was an increasing trend of patient's involvement in decision making as the age increases and, thus, affecting the age-related clinical management.

  17. Managing the effects of aging and reliability improvement

    International Nuclear Information System (INIS)

    Hall, R.E.; Gunther, W.; Boccio, J.L.

    1989-01-01

    Over recent years the electric power generating community has acknowledged the importance of the aging process on plant safety and availability. To cope with time-dependent degradation phenomena that can affect active as well as passive components and lead to unacceptable, unanticipated failures requires research into the mechanisms of the aging process, advances in predictive methods for assessing the aging impact on risk and availability, and a better understanding of power plant operations so that strategies for defending against this pervasive stress can be developed. This paper discusses current research advances and presents a framework to aid in the systematic integration of these three needs. It also discusses current research in the aging effect on electric components. As such it is anchored to research being conducted at Brookhaven National Laboratory in the areas of plant aging, life extension, reliability, performance indication, and risk assessment. (orig.)

  18. Use of configuration management to reduce development costs in metal parts

    International Nuclear Information System (INIS)

    Kalsoom, T.; Ahmad, S.

    2005-01-01

    In development and manufacturing phases of metal parts, design efforts are converted in set of engineering data pack under the given guidelines of Configuration Management (CM). These engineering documents define Configuration Management of metal parts production in a local industry. The development phase is normally less structured and open to Engineering Change Proposals. In our local engineering organizations most of the work done is normally not well documented for future revisions and modernization. This leads to delays in development and increase in production costs of metal parts. This becomes more pronounced if any member of the design team disassociates and leaves the organization. The Configuration Management helps to reduce development costs by providing infrastructure for product identification, documentation, change control, interface control and technical reviews and product audits. Automated or Computer-Assisted CM activities can also be used to shorten response time and increase accuracy and reliability of the produced metal components. (author)

    Orefice, J J; Jennings, M C

    1983-08-01

    Productivity and productivity management are critical to effective case-mix management. Case-mix management expands on traditional productivity management to include the relationship between such intermediate products as patient days, tests and meals, and the ultimate end product, the case. As hospitals search to increase the profitability of specific case types, they must focus on two critical productivity control points. First, they must examine length of stay and ancillary utilization as one level of productivity. Then they must turn to more traditional analyses and review departmental productivity in the production of the intermediate products. No case-mix management system is complete unless it focuses on both of these critical relationships. Part two of this article will explore performance reporting and its role in managing both productivity and case mix.

    2006-03-01

    The need to implement programs for developing leadership and practice improvement skills using an evidence-based practice approach to practice change is becoming more apparent in the health and aged care services. This is no more apparent than in high care residential health and aged care services, where health professionals are increasingly required to provide care for older people with multifocal and complex healthcare needs. This paper describes one of the projects undertaken as part of the Joanna Briggs Institute Commonwealth Department of Health and Ageing Clinical Aged Care Fellowship program from February 2005 to June 2005. This purpose of this particular project was twofold. First it sought to improve the local practice in the prevention and management of constipation and that this practice was performed according to the best available evidence. Second to use the Joanna Briggs Institute Practical Application of Clinical Guidance (PACES) program to implement a process of audit and feedback as a strategy to improve practice. The project was designed to link in with the facility's existing quality improvement program and better practice continence management project. The project was conducted over 6 months and was divided into six stages involving the identification of evidence-based standards of care, an initial audit to determine appropriate sample size, a clinical audit across the facility, planning of the implementation process, implementation of the action plan and re-audit to assess practice change. Overall, the results were extremely positive and demonstrated a real improvement in practice relating to constipation in the project facility. This success, however, needs to be seen in the context of the benefits of having the support of senior management, an existing quality improvement and continence management better practice project, and a culture of clinical review. Although there will always be more work to be done, the success of this project can be

    Over recent years the electric power generating community has acknowledged the importance of the aging process on plant safety and availability. To cope with time-dependent degradation phenomena that can affect active as well as passive components and lead to unacceptable, unanticipated failures requires research into the mechanisms of the aging process, advances in predictive methods for assessing the aging impact on risk and availability, and a better understanding of power plant operations so that strategies for defending against this pervasive stress can be developed. This paper discusses current research advances and presents a framework to aid in the systematic integration of these three needs. As such it is anchored to research being conducted at Brookhaven National laboratory in the areas of plant aging, life extension, reliability, performance indication, and risk assessment

    2012-01-01

    In the present paper, for both units of Laguna Verde Nuclear Power Plant (LVNPP), the Ageing Management Review of the reactor pressure Vessel was carried out, including the identification of the intended functions, the materials and the environments. The evaluation of the ageing effect/mechanism and the Aging management programs currently implemented were prepared. The most important aging effects/ mechanisms are: loss of fracture toughness due to neutron irradiation embrittlement, fatigue, stress corrosion cracking (SCC), general corrosion and erosion-corrosion. The neutron irradiation embrittlement is managed by the reactor vessel materials surveillance program. The fatigue is a Time Limited Aging Analysis (TLAA), for which is necessary to calculate some fatigue usage factors. SCC is managed by, the In service inspections (ISI) program, but also by the Water Chemistry program, including, currently, On Line Noble Chem. The water chemistry program also manages General Corrosion and erosion-corrosion. The results were compared with the GALL report. (author)

    Science.gov (United States)

    Anderson, Beverley

    2018-05-10

    Part 1 of this two-part article provides an overview of bladder cancer and discusses its management. Since publication of a previous article entitled 'Understanding the role of smoking in the aetiology of bladder cancer' ( Anderson, 2009 ), the author has received many requests for an update. This article provides an overview of bladder cancer and its current management practices, underlining the continued role of smoking as the predominant risk factor in the disease's development. The management of bladder cancer is governed by specific guidelines. Management of non-muscle-invasive cancers, including surgical intervention with transurethral resection, and intravesical therapy using chemotherapy and immunotherapy agents, is discussed. Cystectomy (removal of the bladder), is sometimes necessary. Treatments are effective in reducing tumour recurrence, but the effects of the risks and side-effects on the individual's quality of life can be significant. The prevalence of bladder cancer, and the nature of its management make this cancer one of the most expensive for the NHS to treat. The effectiveness of health promotional strategies in increasing peoples' awareness of their risk of developing the disease, and in enabling them to change long-term health behaviours is discussed. The role of the multidisciplinary team is explored, along with that of the uro-oncology cancer nurse specialist. Part 2 will consider the management of muscle-invasive and metastatic bladder cancer.

    2005-01-01

    Demands and requirements for a safe operation of mechanical components during the whole operation life time (plant life management) to assure aging phenomena (aging management) and to prove the integrity (prove of integrity, e.g. in order to exclude large breaks) can be found in guidelines, codes and standards. In the present paper a general concept to proof the integrity as part of the ageing management of pressurized components and systems is presented. The concept is based on the actual material characteristics, the actual as-built configurations and the design of the components and systems including the knowledge of possible failure mechanism during operation. An important part of the assessment is the leak before break behavior and the break preclusion concept. Based on essential research results the developed procedures and methodologies for the assessment of the critical crack sizes as well as the critical loading conditions are reported and discussed. In detail the following aspects have to be treated: (a) evaluation of the as-built status of quality (design, construction, material, fabrication; results of recurrent non destructive examinations up to now, operational experience); (b) determination of the relevant loading conditions by means of in-service monitoring (monitoring of the mode of operation, the water chemistry, the mechanical and thermal stresses, the dynamic loading), emergency and faulted condition loads as specified; (c) evaluation of the actual status of quality with respect to the relevant loading conditions (stress analysis-limitation of the stresses; fatigue analysis-determination of the usage factor; fracture mechanics analysis-determination of crack growth, critical crack sizes and loading conditions); (d) evaluation and extent of the in-service monitoring and recurrent inspections to guarantee the succeeding operation (recurrent non destructive examination - minimum detectable flaw sizes, examination area, examination intervals; leak

    To establish validity of a clinical leadership framework for aged care middle managers (The Aged care Clinical Leadership Qualities Framework). Middle managers in aged care have responsibility not only for organisational governance also and operational management but also quality service delivery. There is a need to better define clinical leadership abilities in aged care middle managers, in order to optimise their positional authority to lead others to achieve quality outcomes. A Delphi method. Sixty-nine experts in aged care were recruited, representing rural, remote and metropolitan community and residential aged care settings. Panellists were asked to rate the proposed framework in terms of the relevance and importance of each leadership quality using four-point Likert scales, and to provide comments. Three rounds of consultation were conducted. The number and corresponding percentage of the relevance and importance rating for each quality was calculated for each consultation round, as well as mean scores. Consensus was determined to be reached when a percentage score reached 70% or greater. Twenty-three panellists completed all three rounds of consultation. Following the three rounds of consultation, the acceptability and face validity of the framework was confirmed. The study confirmed the framework as useful in identifying leadership requirements for middle managers in Australian aged care settings. The framework is the first validated framework of clinical leadership attributes for middle managers in aged care and offers an initial step forward in clarifying the aged care middle manager role. The framework provides clarity in the breadth of role expectations for the middle managers and can be used to inform an aged care specific leadership program development, individuals' and organisations' performance and development processes; and policy and guidelines about the types of activities required of middle managers in aged care. © 2014 John Wiley & Sons Ltd.

    1987-06-01

    The need for pharmacists to develop management expertise through participation in formal courses is now widely acknowledged. Many schools of pharmacy lay the foundations for future management training by providing introductory courses as an integral or elective part of the undergraduate syllabus. The benefit of such courses may, however, be limited by the lack of opportunity for the student to apply the concepts and procedures in a practical working environment. Computer simulations provide a means to overcome this problem, particularly in the field of resource management. In this, the first of two articles, the use of a computer model to demonstrate basic accounting principles is described.

    International Nuclear Information System (INIS)

    Shah, V.N.; Hookhman, C.J.

    1994-01-01

    This paper evaluates aging of light water reactor concrete containments and identifies three degradation mechanisms that have potential to cause widespread aging damage after years of satisfactory experience: alkali-silica reaction, corrosion of reinforcing steel, and sulfate attack. The evaluation is based on a comprehensive review of the relevant technical literature. Low-alkali cement and slow-reacting aggregates selected according to ASTM requirements cause deleterious alkali-silica reactions. Low concentrations of chloride ions can initiate corrosion of the reinforcing steel if the hydroxyl ions are sufficiently reduced by carbonation, leaching, or magnesium sulfate attack. Magnesium sulfate attack on concrete can cause loss of strength and cementitious properties after long exposure. Techniques to detect and mitigate these long-term aging effects are discussed

    Nondestructive evaluation of material damage can contribute to continued safe, reliable, and economical operation of nuclear power plants through their current and renewed license period. The aging mechanisms active in the major light water reactor components are radiation embrittlement, thermal aging, stress corrosion cracking, flow-accelerated corrosion, and fatigue, which reduce fracture toughness, structural strength, or fatigue resistance of the components and challenge structural integrity of the pressure boundary. This paper reviews four nondestructive evaluation methods with the potential for in situ assessment of damage caused by these mechanisms: stress-strain microprobe for determining mechanical properties of reactor pressure vessel and cast stainless materials, magnetic methods for estimating thermal aging damage in cast stainless steel, positron annihilation measurements for estimating early fatigue damage in reactor coolant system piping, and ultrasonic guided wave technique for detecting cracks and wall thinning in tubes and pipes and corrosion damage to embedded portion of metal containments

    The PLiM/PLEx Program applied to the Cernavoda NPP has the goal of ensuring the lifetime target of the plant and its extension in conditions of a continuous, secure and reliable operation by fulfilling at the same time the general licensing requirements as established by the regulation authority CNCAN. The aging management is, according to the organization model, a systematic process implying the following activities specific to the operation: - Planning: Coordination of the aging management activities; - Exploitation: Controlling the aging mechanisms; - Testing: Detection and evaluation of the aging effects; - Maintenance: Controlling the aging effects. All these are interdependent with specific activities in INR Pitesti, related to the research and development which are key elements for controlling effectively the aging process. The model of organizing the aging management developed in this work is applied to the Cernavoda NPP Unit 1

    1981-08-27

    The clinical signs of thyroid disease in older people may differ considerably from those in younger patients. The symptoms are often incorrectly interpreted and attributed to old age. The age is also important to the kind of therapy. The normal clinical hyperthyroidism-indices are not relevant in the diagnosis of hyperthyroidism in older patients. Organic symptoms predominate in old age (loss of weight, muscular asthenia, tremor, cardiac arrhythmia, stenocardia, congestive cardiomyopathy). Most of the time they are wrongly interpreted as additional symptoms of old age. Probably it is not the age that causes the difficulties in hyperthyroidism-diagnostics in old age, but the atypical symptoms of solitary or multilocular adenomas, which increase with advancing age. A special symptom of hyperthyroidism in old age, often misinterpreted, is "apathetic" hyperthyroidism. Radioiodotherapy is indicated in older patients with hyperthyroidism.

    1999-03-08

    As more data gathering, analysis, and tracking tasks are outsourced the need for multiple contractors and military personnel to input, update, access, store, and track Mormation is becoming critical to efficient functioning and managing of environmental projects and programs at military installations. This paper presents two case studies detailing the way two organizations--the Rocky Mountain Arsenal (RMA) in Colorado, and the 611th Air Support Group (611 ASG) in Alaska--are managing complex data using web-based technology. RMA is involved in one of the largest environmental cleanup programs in the Department of Defense. As such, large volumes of environmental data and documents must be generates stored, and tracked. Often these documents are prepared by multiple contractors and are reviewed by several parties or groups. To manage environmental information and to ensure that it meets compliance requirements more efficiently, RMA has developed an electronic document tracking and distribution system. This system allows access to up-to-date information, including a detailed review of all pertinent regulatory and other requirements at RMA. The dynamic system includes milestones, review deadlines, submission deadlines, and other requirements for managing the environmental program. The 611 ASG manages more than 30 remote installations in Alaska, many of which are operated by contractor personnel. These installations contain hundreds of buildings that are constantly being modified because of exposure to harsh arctic climates; some of them have been determined to be eligible for the National Register of Historic Places. To meet regulatory requirements for cultural resources management as well as engineering requirements for upkeep of buildings, a database was developed to store and analyze building data. The database has a web-based interface that allows anyone with the correct access codes to input new data, modify existing data, or query the database using a number of

    Richardson, Clifford; Adams, Nicola; Poole, Helen

    2006-09-01

    The aim of this article was to present the ways that nurses can integrate psychological approaches into their management of chronic pain conditions using a biopsychosocial framework. Communication, the importance of the patient-practitioner interaction, the role of education and provision of information, reassurance and reduction of anxiety and the use of coping strategies training in the management of chronic pain are reviewed alongside the key skills of nursing. This is the second part of a two-part article. Part 1 was a discussion of psychosocial factors associated with chronic pain conditions and the psychological approaches used in the management of these conditions. It is identified that key nursing skills often equate to the requirements of the psychological approaches, therefore specific techniques from a cognitive-behavioural framework can be readily applied, integrated and used by nurses in the management of chronic pain conditions. Commonly utilized nursing skills are similar to those required for cognitive-behavioural therapy. It is reasonable to assume therefore that nurses can and should be involved in effectively managing the psychological aspects associated with chronic pain conditions.

  18. U.S.-NPAR approach to managing aging in operating nuclear power plants

    International Nuclear Information System (INIS)

    Bosnak, R.; Vagins, M.; Vora, J.

    1991-01-01

    Aging degradation in operating nuclear power plants must be managed to prevent safety margins from eroding below the levels provided in plant design bases. The NPAR program and other aging-related programs conducted under the auspices of the US NRC Office of Nuclear Regulatory Research are developing needed technical bases and guidance for understanding and managing aging in operating nuclear power plants (NPP) of all ages. Results from these programs, together with relevant information developed by industry are implemented through various ongoing NRC and industry programs. The aging management process central to these efforts consists of three key element: 1) selection and prioritization of components, systems, and structures (CSS) in which aging must be managed, 2) understanding of the relevant aging mechanisms and rates of degradation processes in these CSS, and 3) managing degradation through effective inspection, surveillance, condition monitoring, trending, preventive and corrective maintenance, and mitigation. This paper provides a historical perspective on the aging related research programs sponsored by the Office of U.S. Nuclear Regulatory Research. Also, briefly described are the major element of the NPAR program and its status and results or accomplishments. In the process the authors emphasize the need for total industry commitment and participation in implementing programs for understanding and managing aging in operating nuclear power plants. 'Aging' is universal in nature. No industrial complex including NPP should be considered immune from its effects. For NPP aging is manageable its ti symptoms are recognized and predicted, if it is monitored and appropriate steps are taken for timely mitigation of age-related degradation. (author)

    2012-07-01

    Full Text Available Introduction & Objective: Fever is very common in children and is usually due to self-limiting viral infections. Management of fever is based on culture, community and religion of people all over the world. Parental concerns arise in part because of the belief that fever is a disease rather than a symptom or sign of illness. Misconceptions about childhood fevers heighten parents' concerns leading to inappropriate use of antipyretic drugs or overdosing may cause drug toxicity and frequent use of health care services. This study aimed to identify parental views of fever management in their children aged 0-5 yr.Materials & Methods: In this cross sectional study, 350 parents with children less than 5 years referred to various units of clinics covered by community oriented center of Kermanshah, completed the research questionnaire. Validity and reliability of the questionnaire were determined and the data was analyzed by SPSS Software.Results: Findings showed that the first medical care was sponging (53.1%. Sponging with saltwater was common (47.7% and Over - the - counter medications were (30%. Acetaminophen was the first drug in 90% of the cases. However, many parents express high levels of anxiety so that they seek for self-medication with antibiotic 34% of the cases.

    1997-01-01

    Part 1 of this series organizes and discusses the sources of value against a background of an evolving managed care market. Part 2 will present, in more detail, the marketing and financial challenges to organizational positioning and performance across the four stages of managed care. What are the basic principles or tenets of value and how do they apply to the health care industry? Why is strategic positioning so important to health care organizations struggling in a managed care environment and what are the sources of value? Service motivated employees and the systems that educate them represent a stronger competitive advantage than having assets and technology that are available to anyone. As the health care marketplace evolves, organizations must develop a strategic position that will provide such value and for which the customer will be willing to pay.

    Hospital management has experienced significant progress with the evolution of the Romanian health system reform, it has made strides in terms of resource allocation and cost control, new systems for classification, evaluation and monitoring (DRGs, SIUI, CaPeSaRo) were implemented, some taken from other countries and adapted to local conditions, but not always integrated with the other components and sometimes incompletely implemented and developed. This material does not offer definite solutions to current problems. It only briefly addresses the main aspects of hospital activity, and points out some failures with whom hospital managers are presently faced. Once the problems are identified it creates prerequisites for solving them, it opens channels of research and development of new methodologies or correlation of the existing deficient workflows that can be corrected.

    2012-01-01

    Most component failures stem from effects of one or multiple ageing mechanism(s). Ageing management is one of the most robust measures to prevent failure and to maintain and increase safety of nuclear power plants. Based on Nuclear Safety Guideline on Ageing Management (NS-G-2.12) published by IAEA in 2009, the paper summarizes main ageing management activities required for all stages of life cycle of NPPs, including design, construction/manufacture, commissioning, operation, life extension for long-term operation and decommissioning. Interactive relations of ageing management in successive stages are analyzed. Implementation of the IAEA Guideline in comprehensive way will bring new challenges to design conception, modes of construction, manufacture, commissioning, equipment qualification, O and M, licensing, life extension and decommissioning for NPPs, however, it will be beneficial to enhance nuclear safety level, especially to promote development of nuclear power in China in a safe, reliable, profitable and sustainable way.

    Introducing the new, realistic loyalty pact between employer and employee. The employer-employee relationship is broken, and managers face a seemingly impossible dilemma: the old model of guaranteed long-term employment no longer works in a business environment defined by continuous change, but neither does a system in which every employee acts like a free agent. The solution? Stop thinking of employees as either family or as free agents. Think of them instead as allies. As a manager you want your employees to help transform the company for the future. And your employees want the company to help transform their careers for the long term. But this win-win scenario will happen only if both sides trust each other enough to commit to mutual investment and mutual benefit. Sadly, trust in the business world is hovering at an all-time low. We can rebuild that lost trust with straight talk that recognizes the realities of the modern economy. So, paradoxically, the alliance begins with managers acknowledging that ...

    2017-05-15

    Purpose The purpose of this paper is to examine whether occupational health and safety (OHS) management used to manage musculoskeletal disorders (MSDs) in the aged care sector reflects contemporary research evidence of best practice to reduce the incidence of these disorders. Design/methodology/approach In total, 58 interviews were conducted with managers and supervisors in the aged care sector across four organisations in Australia. Policies and procedures relating to MSDs were reviewed for each organisation. Findings Policies and procedures for managing MSDs do not reflect contemporary evidence, which supports a complex aetiology, related to a range of physical and psychosocial workplace factors. Despite strong evidence that psychosocial factors contribute to MSD development, these were not included in the policies and procedures reviewed. Findings from the interviews management practices including leadership and various components of HRM were functioning well but fragmentation was evident due to the challenging nature of the aged care sector. Practical implications To address the significant burden of MSDs in the aged care sector, policies and procedures need to include coverage of psychosocial and physical workplace factors. The development of systematic and integrated OHS management at the workplace level may play an important role in the effective management of MSDs. Originality/value This study offers insights into the previously unexplored area of MSD risk management and the role of management practices such as HRM in the aged care sector.

  7. A Proactive Aging/Asset Management Model to Optimize Equipment Maintenance Resources Over Plant Lifetime

    2002-01-01

    Experience has shown that proactive aging/asset management can best be defined as an ongoing process. Station goals directly supported by such a process include reducing Unplanned Capability Loss Factor and gaining the optimum value from maintenance and aging management budgets. An effective aging/asset management process must meet evolving and sometimes conflicting requirements for efficient and reliable nuclear power plant operation. The process should identify most likely contributors before they fail, and develop cost-effective contingencies. Current trends indicate the need for focused tools that give quantitative input to decision-making. Opposing goals, such as increasing availability while optimizing aging management budgets, must be balanced. Recognizing the importance of experience in reducing the uncertainty inherent in predicting equipment degradation rates, nuclear industry demographics suggest the need to capture existing expert knowledge in a usable form. The Proactive Aging/Asset Management Process has been developed to address these needs. The proactive approach is a process supported by tools. The process identifies goals and develops criteria - including safety, costs, and power production - that are used to prioritize systems and equipment across the plant. The process then draws upon tools to most effectively meet the plant's goals. The Proactive Aging/Asset Management Model TM is one software-enabled tool designed for mathematical optimization. Results assist a plant in developing a plant-wide plan of aging management activities. This paper describes the proactive aging/asset management process and provides an overview of the methodology that has been incorporated in a model to perform a plant-wide optimization of aging management activities.

    It has been proposed that the hypothalamus helps to control ageing, but the mechanisms responsible remain unclear. Here we develop several mouse models in which hypothalamic stem/progenitor cells that co-express Sox2 and Bmi1 are ablated, as we observed that ageing in mice started with a substantial loss of these hypothalamic cells. Each mouse model consistently displayed acceleration of ageing-like physiological changes or a shortened lifespan. Conversely, ageing retardation and lifespan extension were achieved in mid-aged mice that were locally implanted with healthy hypothalamic stem/progenitor cells that had been genetically engineered to survive in the ageing-related hypothalamic inflammatory microenvironment. Mechanistically, hypothalamic stem/progenitor cells contributed greatly to exosomal microRNAs (miRNAs) in the cerebrospinal fluid, and these exosomal miRNAs declined during ageing, whereas central treatment with healthy hypothalamic stem/progenitor cell-secreted exosomes led to the slowing of ageing. In conclusion, ageing speed is substantially controlled by hypothalamic stem cells, partially through the release of exosomal miRNAs.

    Laguna Verde Nuclear Power Plant (LVNPP) located in Veracruz, Mexico is a BWR plant, two Units with 810 MWe each one, Unit 1 (1989) and Unit 2 (1990). The Equipment Qualification (EQ) Group at the Nuclear Research National Institute (ININ) has been working with the plant on tasks to develop the LVNPP cables Aging Management Program (AMP), as part of the technical basis to extend the operational life of the plant through license renewal up to 60 years. LVNPP cables are qualified for 40 years plus a LOCA DBA in accordance with 10.CFR 50.49 and the IEEE Std-323 and IEEE St. 383. The first studies for cables AMP have been performed with samples of safety related I and C cables taken from the LVNPP warehouse, similar brands and models as installed at the plant. ININ applied the condition monitoring techniques to these samples to identify predictive degradation and to establish the methodology for cables AMP, focused to the LVNPP license renewal. Cable tests program has been running at the EQ Lab in ININ, performing accelerated aging by steps up to 60 years and to 40 years plus a LOCA test. Determination for Activation Energy (Ea) and Oxidation Induction Time (OIT) methods were developed applying a DSC/TGA calorimeter. (author)

    2005-02-01

    The lower third of the face and neck have distinct changes that occur with aging. These changes can be globally and dramatically addressed with a traditional rhytidectomy. However, as the demographics of facial plastic surgery patients evolve, patients seek increasingly less invasive procedures that will result in faster recovery time and less postoperative morbidity. To accommodate this change, today's facial plastic surgeon must include less invasive procedures in the treatment strategies for the lower face and neck. Correct, patient-specific procedure selection and patient education can yield results similar to those of a traditional facelift. This article discusses options available for treatment of the lower face and neck.

  13. Managing age discrimination: an examination of the techniques used when seeking employment.

    Science.gov (United States)

    Berger, Ellie D

    2009-06-01

    This article examines the age-related management techniques used by older workers in their search for employment. Data are drawn from interviews with individuals aged 45-65 years (N = 30). Findings indicate that participants develop "counteractions" and "concealments" to manage perceived age discrimination. Individuals counteract employers' ageist stereotypes by maintaining their skills and changing their work-related expectations and conceal age by altering their résumés, physical appearance, and language used. This research suggests that there is a need to reexamine the hiring practices of employers and to improve legislation in relation to their accountability.

    McNorgan, J.D. (Southern California Gas Co., Los Angeles, CA (United States))

    1993-05-01

    Southern California Gas Company, transports billions of cubic feet of natural gas through large-diameter, high-pressure transmission lines, across hundreds of miles of varying terrain, to satisfy the needs of over four and a half million customers. Operating an aging gas system can be truly expensive. Repair costs are very high. Recent figures experienced by our company show that it cost over $800 to repair a main leak, $400 to replace a service, and over $40 a foot to replace even small sized mains. A hidden cost is the effect of the physical limitations imposed by an aging system. It could be under-sized, or limited to a low pressure, thus restricting the volume of gas that can be delivered. Additionally there is the potential loss of valuable gas through leaks or blow downs when making repairs or replacements, and the damage it could do to the environment. For some years Southern California Gas Company has had on-going special and routine pipe replacement programs. The special pipe replacement program is driven primarily to increase the safety of the system, while at the same time improving reliability of service to the customers and reducing their total costs.

    The Dalat Nuclear Research Reactor (DNRR) is a pool type research reactor which was reconstructed in 1982 from the previous 250 kW TRIGA-MARK II reactor. The reactor core, the control and instrumentation system, the primary and secondary cooling systems as well as other associated systems were newly designed and installed. The renovated reactor reached its initial criticality in November 1983 and attained its nominal power of 500 kW in February 1984. Since then DNRR has been operated safely. Retained structures of the former reactor such as the reactor aluminum tank, the graphite reflector, the thermal column, the horizontal beam tubes and the radiation concrete shielding are 35 years old. During the recent years, in-service inspection has been carried out, the reactor control and instrumentation system were renovated due to ageing and obsolescence of its components, reactor general inspection and refurbishment were performed. Efforts are being made to cope with ageing of old reactor components to maintain safe operation of the DNRR. (author)

    It is expected that nuclear power generation will bear main electric power supply for long term. For this purpose, by applying proper preventive maintenance to the nuclear power plants in operation, the maintenance of high reliability and the rate of plant operation is extremely important. Especially it has been strongly demanded to execute efficiently the periodic inspection which is carried out every year to shorten its period and increase the rate of operation, and to maintain the reliability by the proper maintenance for the aged plants with long operation years. As to efficient and short periodic inspection, the preparation is advanced by the guidance of electric power companies aiming at realizing it in nearest fiscal year, and further, effort is exerted for the development of technology in long term to optimize periodic inspection. For securing the reliability of aged plants, it is important to do proper inspection and diagnosis and to take the countermeasures by repair and replacement, based on the grasp of secular change mechanism and the evaluation of life of machinery, equipment and materials. In particular, effort is exerted for the development of maintenance technology for reactor pressure vessels and in-core equipment which are hard to access. The confirmation of the function of remote operation equipment and the establishment of execution condition are carried out by uisng the full scale mock-up of BWR plant. The problems in maintenance service and the activities and results of reliability improvement are reported. (K.I.)

    The aim of this study was to determine oxygen saturation levels in the dental pulp of maxillary premolars in different age groups. A total of 120 human maxillary premolars with normal dental pulps were selected covering the following age groups: 20-24, 25-29, 30-34, 35-39 and 40-44 years (n=24 each group). Oxygen saturation was assessed using pulse oximetry. Analysis of variance was used to assess differences in oxygen saturation levels and Tukey's test was used to identify the age groups that differed from each other. Significance was set at 0.05. Mean oxygen saturation of 120 premolars was 86.20% considering all age groups. Significantly reduced levels were found in the oldest group compared to the other groups: 40 to 44 years - 80.00% vs. 89.71, 87.67, 88.71, and 84.80% for age groups 20-24, 25-29, 30-34, 35-39 years, respectively. The mean oxygen saturation levels were similar between 20 and 39 years of age (86.20%) in the whole sample, but reduced significantly in the 40-44-year age group, suggesting that older patients present lower oxygen saturation results even in the absence of pulp tissue injury.

    The demonstration that the effects of degradation in the components of PWR internals are adequately managed is essential for maintaining a healthy fleet and ensuring the continued functionality of the reactor internals. It is also very important to determine when and where irradiation susceptibility may occur for the continued operation. This paper introduces the aging management strategies and requirements for PWR internals components and discusses effects of irradiation aging results from the functionality assessments based on the categorization of internal components. This paper introduces aging management strategies and requirements for PWR internals components. The aging management requirements for PWR internals are specified in four final component groups, which are Primary, Expansion, Existing Program and No Additional Measures. Among these groups, Primary groups include any restriction on general applicability, degradation mechanism, forward link to any Expansion components, examination method, initial examination and frequency, and examination coverage and accessibility. Expansion groups are backward link to the Primary component.

    The malnutrition of children under five years of age constitutes a major public health problem in most developing countries. A cross-section study was carried in 2003 in the northern part of Côte d'Ivoire to determine the prevalence of chronic malnutrition and to identify risk factors among children under five years of age living in urban and rural areas of the northern part of Côte d'Ivoire. A total of 292 and 268 children under five years of age residing respectively in urban and rural areas were included in the study. Their median age was 24 months. Chronic malnutrition was more frequent in children from rural areas (39.9%) than in those living in urban areas (16.7%). Malnutrition was significantly associated with the type of food consumed by children under two years of age in urban areas, and it was strongly linked to emaciation of the mother and presence of childhood fever in rural areas. In light of these results, we advocate a healthy diet and adequate health status for the mother and child to improve the nutritional status of children. Moreover, these results need to be completed and complemented by further studies for more detailed information to contribute to a better definition of actions to fight efficiently against malnutrition among children of the northern part of Côte d'Ivoire.

    1996-02-01

    Continued operation of nuclear power plants for periods that extend beyond their original 40-year license period is a desirable option for many U.S. utilities. U.S. Nuclear Regulatory Commission (NRC) approval of operating license renewals is necessary before continued operation becomes a reality. Effective aging management for plant components is important to reliability and safety, regardless of current plant age or extended life expectations. However, the NRC requires that aging evaluations be performed and the effectiveness of aging management programs be demonstrated for components considered within the scope of license renewal before granting approval for operation beyond 40 years. Both the NRC and the utility want assurance that plant components will be highly reliable during both the current license term and throughout the extended operating period. In addition, effective aging management must be demonstrated to support Maintenance Rule (10 CFR 50.65) activities.

    Over time, the radial collector wells of the Belgrade Groundwater Source, located in the alluvial sediments of the Sava River, exhibit a decline in discharge and a reduction in operating efficiency due to well ageing. An increase in hydraulic losses at the lateral screens, due to chemical and biochemical clogging, has been identified as the primary cause. Certain hydrogeological, hydrochemical and microbiological parameters reflect the well-ageing process and can, therefore, be considered as its indicators. An indicator-based determination of scale is an important aspect in the selection of appropriate well locations, structural characteristics, and maintenance approaches. Well ageing was studied over a period of 5 years (2005-2009). The objective was to investigate the causes of well ageing. The correlations established between the groundwater redox potential, the total iron concentration in groundwater, the grain-size distribution of the aquifer, and well discharge, are presented in the paper.

    The goals of the well-child examination in school-aged children (kindergarten through early adolescence) are promoting health, detecting disease, and counseling to prevent injury and future health problems. A complete history should address any concerns from the patient and family and screen for lifestyle habits, including diet, physical activity, daily screen time (e.g., television, computer, video games), hours of sleep per night, dental care, and safety habits. School performance can be used for developmental surveillance. A full physical examination should be performed; however, the U.S. Preventive Services Task Force recommends against routine scoliosis screening and testicular examination. Children should be screened for obesity, which is defined as a body mass index at or above the 95th percentile for age and sex, and resources for comprehensive, intensive behavioral interventions should be provided to children with obesity. Although the evidence is mixed regarding screening for hypertension before 18 years of age, many experts recommend checking blood pressure annually beginning at three years of age. The American Academy of Pediatrics recommends vision and hearing screening annually or every two years in school-aged children. There is insufficient evidence to recommend screening for dyslipidemia in children of any age, or screening for depression before 12 years of age. All children should receive at least 400 IU of vitamin D daily, with higher doses indicated in children with vitamin D deficiency. Children who live in areas with inadequate fluoride in the water (less than 0.6 ppm) should receive a daily fluoride supplement. Age-appropriate immunizations should be given, as well as any missed immunizations.

    At WWER NPPs the horizontal steam generators (SGs), are used that differ in design concept from vertical SGs mostly used at western NPPs. Reliable operation of SG heat-exchanging tubes is the crucial worldwide problem for NPP of various types. According to the operation feedback the water chemistry is the governing factor affecting operability of SG tubing. The secondary side corrosion is considered to be the main mechanism of SG heat-exchanging tubes damage at WWER plants. To make the assessment of the tubing integrity the combination of pressure tests and eddy-current tests is used. Assessment of the tubing performance is an important part of SG life extension practice. The given paper deals with the description of the tube testing strategy and the approach to tube integrity assessment based on deterministic and probabilistic methods of fracture mechanics. Requirements for eddy-current test are given as well. Practice of condition monitoring and implementing the database on steam generators operation are presented. The approach to tubes plugging criteria is described. The research activities on corrosion mechanism studies and residual lifetime evaluation are mentioned. (authors)

    Several OECD Member Countries have agreed to establish the OECD/NEA 'Component Operational Experience, Degradation & Ageing Programme' (CODAP) to encourage multilateral co-operation in the collection and analysis of data relating to degradation and failure of metallic piping and non-piping metallic passive components in commercial nuclear power plants. The scope of the data collection includes service-induced wall thinning, part through-wall cracks, through-wall cracks with and without active leakage, and instances of significant degradation of metallic passive components, including piping pressure boundary integrity. The OECD/NEA Committee on the Safety of Nuclear Installations (CSNI) acts as an umbrella committee of the Project. CODAP is the continuation of the 2002-2011 'OECD/NEA Pipe Failure Data Exchange Project' (OPDE) and the Stress Corrosion Cracking Working Group of the 2006-2010 'OECD/NEA SCC and Cable Ageing project' (SCAP). OPDE was formally launched in May 2002. Upon completion of the 3rd Term (May 2011), the OPDE project was officially closed to be succeeded by CODAP. SCAP was enabled by a voluntary contribution from Japan. It was formally launched in June 2006 and officially closed with an international workshop held in Tokyo in May 2010. Majority of the Member Organizations of the two projects were the same, often being represented by the same person. In May 2011, thirteen countries signed the CODAP 1st Term agreement (Canada, Chinese Taipei, Czech Republic, Finland, France, Germany, Korea (Republic of), Japan, Slovak Republic, Spain, Sweden, Switzerland and United States of America). The 1st Term (2011-2014) work plan includes the preparation of Topical Reports to foster technical cooperation and to deepen the understanding of national differences in ageing management. The Topical Reports constitute CODAP Event Database and Knowledge Base insights reports and as such act as portals for future in-depth studies of

    Since the publication of the Duchenne muscular dystrophy (DMD) care considerations in 2010, multidisciplinary care of this severe, progressive neuromuscular disease has evolved. In conjunction with improved patient survival, a shift to more anticipatory diagnostic and therapeutic strategies has occurred, with a renewed focus on patient quality of life. In 2014, a steering committee of experts from a wide range of disciplines was established to update the 2010 DMD care considerations, with the goal of improving patient care. The new care considerations aim to address the needs of patients with prolonged survival, to provide guidance on advances in assessments and interventions, and to consider the implications of emerging genetic and molecular therapies for DMD. The committee identified 11 topics to be included in the update, eight of which were addressed in the original care considerations. The three new topics are primary care and emergency management, endocrine management, and transitions of care across the lifespan. In part 1 of this three-part update, we present care considerations for diagnosis of DMD and neuromuscular, rehabilitation, endocrine (growth, puberty, and adrenal insufficiency), and gastrointestinal (including nutrition and dysphagia) management.

    Based on the Atomic Energy Act, the NRC issues licenses for commercial power reactors to operate for up to 40 years and allows these licenses to be renewed for up to another 20 years. NRC has approved license renewal for well over 50% of U.S. located reactors originally licensed to operate for 40 years. Of these 104 reactors (69 PWRs, 35 BWRs), the NRC has issued renewed licenses for 71 units and is currently reviewing applications for another 15 units. As of May 1, 2012, ten plants at nine sites had entered their 41st year of operation and thus are in their first period of extended operation (PEO). Five more plants will enter the PEO by the end of 2012. One foundation of the license renewal process has been license renewal guidance documents (LRGDs). The U.S. Nuclear Regulatory Commission (NRC) revised key guidance documents used for nuclear power license renewal in 2010 and 2011. These include NUREG-1800, 'Standard Review Plan for Review of License Renewal Applications,' revision 2 (SRP-LR), and NUREG-1801, 'Generic Aging Lessons Learned (GALL) Report,' revision 2 (GALL Report). The guidance documents were updated to reflect lessons learned and operating experience gained since the guidance documents were last issued in 2005. (author)

    Electrical cables constitute one of the most important components of NPP in terms o maintenance, safety and availability of the plant. Due to their large extension (thousands of kilometers) it is impossible to fully replace them and aging management becomes essential for long term operation of NPP. Since Atucha II is under construction there was a good opportunity to establish and implement a holistic cable aging management program from the beginning according to the state of the art in this field. The scope of this program involves safety related cables, including EQ cables and non EQ cables as well. Due to the diversity of the installed cables is impossible to address an aging management program of every single specimen. However it is possible to establish 'cables families' of similar aging behavior based on insulation and jacket material, manufacture, etc Several aging management strategies were set for the different 'cables families'. These strategies include cables deposit in plant, elaboration of procedures of visual and tactile inspection, NDE techniques, etc Currently the aging management program is being implemented covering topic such as: Cable screening and grouping. Review of EQ documentation and conventional qualification information referring to the installed cables. Establishment of base line of condition monitoring techniques. Calibration and set up of test parameters for NDE techniques. Aging mechanism characterization and determination of. Design construction and installation of cable deposit in plant (author)

    Today's prescriptions for treating spasticity may include pharmacological, surgical, or physical procedures. All derive their rationale from the classical concepts of decerebrate rigidity and of brain organization as discussed in Part I. This paper describes the advantages and disadvantages of these current treatment procedures and proposes that recent discoveries about the "recovery" capabilities of the central nervous system may influence the means for managing spasticity in the future.

Three hundred fifty-eight children 3 to part-time patching group (difference, 5.4%; lower limit of 1-sided exact 95% confidence interval, 2.0%; P = 0.004, 1-sided hypothesis test). Deterioration of previously untreated childhood IXT over a 6-month period is uncommon with or without patching treatment. Although there is a slightly lower deterioration rate with patching, both management approaches are reasonable for treating children 3 to 10 years of age with IXT.

    2011-01-01

    A review of the Pennsylvania Game Commission's (PGC) deer management program and public concern about predator impacts on deer (Odocoileus virginianus) populations compelled the PGC to investigate the role of age ratios in developing management recommendations. Age ratios, such as proportion of juveniles in the antlerless harvest, may provide an index to population productivity and predator impacts. We estimated proportion of juveniles in the antlerless harvest from hunter-killed deer, population trends using the Pennsylvania (USA) sex–age–kill model, and reproduction from road-killed females. Using these estimates and a simulation model, we concluded that no single age-ratio value would serve as a reliable measure of population status. Wildlife Management Unit-specific trends in proportion of juveniles in the antlerless harvest and population trends provided the most relevant management information. We also provide an example decision chart to guide management actions in response to declining age ratios in the harvest. Although predator management activities and juvenile survival studies are often desired by the public, our decision-chart example indicated a number of deer management options exist before investing resources in predator management activities and juvenile survival studies.

    Full Text Available The Morris water maze (MWM is a tool for assessment of age-related cognitive deficits. In our work, MWM was used for appraisal of cognitive deficits in 11-month-old rats and investigation of the effect exerted by training in the Morris water maze on the redox mechanisms in rat brain parts. Young adult (3-month-old and aged (11-month-old male rats were trained in the water maze. Intact animals of the corresponding age were used as the reference groups. The level of pro- and antioxidant capacity in brain tissue homogenates was assessed using the chemiluminescence method.Cognitive deficits were found in 11-month-old rats: at the first day of training they showed only 30% of successful MWM trials. However, at the last training day the percentage of successful trials was equal for young adult and aged animals. This indicates that cognitive deficits in aged rats can be reversed by MWM training. Therewith, the MWM spatial learning procedure itself produces changes in different processes of redox homeostasis in 11-month-old and 3-month-old rats as compared to intact animals. Young adult rats showed a decrease in prooxidant capacity in all brain parts, while 11-month-old rats demonstrated an increase in antioxidant capacity in the olfactory bulb, pons + medulla oblongata and frontal lobe cortex. Hence, the MWM procedure activates the mechanisms that restrict the oxidative stress in brain parts. The obtained results may be an argument for further development of the animal training procedures aimed to activate the mechanisms responsible for age-related cognitive deficits. This may be useful not only for the development of training procedures applicable to human patients with age-related cognitive impairments, but also for their rehabilitation.

    assessment of the future field data. Subtle changes to plant operation and also the unique plant-specific details of materials and design often can have a significant impact on the life capability of this complicated equipment. From the plant-specific assessments, and from the experience from our R and D program and utility interaction, AECL has developed a detailed proactive SG aging management strategy for long and reliable life capability (to 50 years). This proactive strategy has a number of important elements that are recommended to be incorporated into current plant programs. With CANDU plants continuing operation with aging equipment, such as steam generators, AECL is continuing to undertake comprehensive programs to support operations and provide enhanced technologies for performance attainment and improvement in inspection, surveillance and performance/safety analysis methodologies. These technologies are also continuously improved by programs that are targeted to important in-service degradation mechanisms, understanding of the system/equipment tolerance to this degradation, and to measures that can be applied to both new reactors and back fitted to existing plants. Systematic and continuous feedback of experience from operations to the performance programs is another important part of the approach. This paper will outline the results of several CANDU SG condition assessments, and place the recommendations from these assessments in context with effective aging Management programs that need to be followed to achieve economic life. For CANDU 6 utilities, which have had a very good steam generator service record with little or no significant active degradation to date, the paper will outline the approach to proactive aging Management that will see equipment through to long and reliable extended life. Also mentioned will be examples of AECL performance improvement and operations support programs for steam generators. (author)

That single event increased life-span several decades for the majority of people living in first world nations. However, protection against lethal infection provided by antibiotics exposed older humans to a wide variety of life-threatening diseases resulting from disintegration of internal order during senescence. These intrinsic diseases including diabetes, stroke, heart attack, cancer, and a multitude of others, resulted in creation of medical subspecialties. Although each specialty focused upon different organs and systems, they all administered treatment in response to disease. In other words, the operative model for modern medicine which deals with intrinsic disease is the same as that which was used for extrinsic disease, ie, a disease occurs and then it is treated. However, unlike therapy for infection which generally cures disease, treatment of intrinsic diseases only provides symptomatic relief, rarely affecting the underlying causes. Also, because it targets specific symptoms, this approach treats the disease condition as an isolated entity, independent of other bodily functions. Thus, the cardiologist, neurologist, allergist, and dermatologist focus their attentions only upon problems occurring within the system(s limited by their training. Accordingly, they prescribe drugs that were created to specifically suppress or relieve symptoms directly related to the problem(s. Despite the fact that this approach rarely provides a cure, it is effective in extending life, if not necessarily its quality, because many of the symptoms of intrinsic disease such as extremely high blood pressure, severe hyperglycemia, or profound breathing difficulties can lead to fatal complications.

    The selection and development of strong executive talent to manage the utility industry is essential if some of the controversy and confusion over the role and policies of utilities is to be resolved. The industry has traditionally trained and elevated executives within the organization, but new technical developments have changed the managerial skills required of executives. Today's manager needs an understanding of the total industry regardless of his initial training, the politics involved in advocating issues, and the need to keep costs down. To develop managerial continuity, utilities can institute job rotation as part of their management training program. The option to bring in executives from outside the company allows more stringent standards and introduces new ideas. Competitive salaries increase the opportunity to attract and retain talent. The Board of Directors can actively develop a flexible organizational structure that allows the executive group to adjust to changing demand. (DCK)

    The purpose of this document is to establish the foundation for the selection and implementation of technologies to be demonstrated in the Mixed Waste Management Facility, and to select the technologies for initial pilot-scale demonstration. Criteria are defined for judging demonstration technologies, and the framework for future technology selection is established. On the basis of these criteria, an initial suite of technologies was chosen, and the demonstration implementation scheme was developed. Part 1, previously released, addresses the selection of the primary processes. Part II addresses process support systems that are considered ''demonstration technologies.'' Other support technologies, e.g., facility off-gas, receiving and shipping, and water treatment, while part of the integrated demonstration, use best available commercial equipment and are not selected against the demonstration technology criteria

    The U.S. Fish and Wildlife Service conducts an annual Waterfowl Parts Collection Survey to estimate composition of harvested waterfowl by species, sex, and age (i.e., juv or ad). The survey relies on interpretation of duck wings by a group of experienced biologists at annual meetings (hereafter, flyway wingbees). Our objectives were to estimate accuracy of age assignment at flyway wingbees and to explore how accuracy rates may influence bias of age composition estimates. We used banded mallards (Anas platyrhynchos; n = 791), wood ducks (Aix sponsa; n = 242), and blue-winged teal (Anas discors; n = 39) harvested and donated by hunters as our source of birds used in accuracy assessments. We sent wings of donated birds to wingbees after the 2002–2003 and 2003–2004 hunting seasons and compared species, sex, and age determinations made at wingbees with our assessments based on internal and external examination of birds and corresponding banding records. Determinations of species and sex of mallards, wood ducks, and blue-winged teal were accurate (>99%). Accuracy of aging adult mallards increased with harvest date, whereas accuracy of aging juvenile male wood ducks and juvenile blue-winged teal decreased with harvest date. Accuracy rates were highest (96% and 95%) for adult and juvenile mallards, moderate for adult and juvenile wood ducks (92% and 92%), and lowest for adult and juvenile blue-winged teal (84% and 82%). We used these estimates to calculate bias for all possible age compositions (0–100% proportion juv) and determined the range of age compositions estimated with acceptable levels of bias. Comparing these ranges with age compositions estimated from Parts Collection Surveys conducted from 1961 to 2008 revealed that mallard and wood duck age compositions were estimated with insignificant levels of bias in all national surveys. However, 69% of age compositions for blue-winged teal were estimated with an unacceptable level of bias. The low

    The K-Ar age determination of the volcanic rocks from the Nyuto-Takakura volcano group, northeast Japan, was carried out. Nyuto-Takakura volcanoes are situated in the southern part of the Sengan geothermal area. And the Young Volcanic Rocks in the area were already divided into the Early stage volcanics (erupted in Matsuyama reversed epoch or more older epoch) and the Later stage volcanics (erupted in Brunhes normal epoch) by accumulated paleomagnetic and K-Ar age data. The results in this study are as follows; Nyuto Volcano: 0.63±0.06, 0.36±0.07 Ma, Sasamoriyama Volcano: 0.09±0.07, 0.3±0.3 Ma, Marumori Lava Dome: 0.4±0.3, 0.31±0.12 Ma, Mikadoyama Lava Dome: <1 Ma, Takakurayama-Kotakakurayama volcano: 1.4±0.5, 1.0±0.4, <0.4 Ma. The determinated ages are concordant with the volcanic stratigraphy and the paleomagnetic data. Nyuto Volcano, Sasamoriyama Volcano, Marumori Lava Dome, Mikadoyama Lava Dome and upper part of the Takakurayama-Kotakakurayama Volcano are interpreted to be erupted in Brunhes normal epoch. The volcanic rocks from the lower part of the Takakurayama-Kotakakurayama volcano show normal magnetic polarity, so they are interpreted to be erupted in Jaramillo normal polarity event. The Early stage volcanics and the Later stage volcanics in the studied area are tend to be distributed in the central part and the outer part of the area, respectively. But the determinated ages in this study show that there is no simple migration of the eruption center of the volcanic rocks from the central part to the peripheral part. There is no geothermal manifestation or alteration area around the Sasamoriyama Volcano and the Marumori Lava Dome, which are the youngest volcanoes in the studied area. So it is concluded that there is no direct correlation between the eruption age of the nearest volcano and the geothermal activity. (author)

    School-aged children (kindergarten through early adolescence) are establishing patterns of behavior that may last a lifetime; therefore, it is important to counsel these patients about healthy lifestyle practices during well-child examinations. Children and families should be advised to eat a diet high in fruits, vegetables, whole grains, low-fat or nonfat dairy products, beans, fish, and lean meats, while limiting sugar, fast food, and highly processed foods. Children should engage in at least 60 minutes per day of moderate to vigorous physical activity, and screen time (e.g., television, computer, video games) should be limited to no more than one to two hours of quality programming daily. Most school-aged children require 11 hours of sleep per night. Decreased sleep is associated with behavioral issues, decreased concentration at school, and obesity. Children should brush their teeth twice per day with a toothpaste containing fluoride. Unintentional injury is the leading cause of death in this age group in the United States, and families should be counseled on traffic, water, sports, and firearm safety. Because high-risk behaviors may start in early adolescence, many experts recommend screening for tobacco, alcohol, and drug use beginning at 11 years of age. Sexually active adolescents should be counseled on protecting against sexually transmitted infections, and should be screened for these infections if indicated.

    Research reactors have played an important role in several scientific fields for around 60 years: in the development of nuclear science and technology; in the valuable generation of radioisotopes for various applications; and in the development of human resources and skills. Moreover, research reactors have been effectively utilized to support sustainable development in more than 60 countries worldwide. More than half of all operating research reactors are now over 40 years old, with many exceeding their originally conceived design life. The majority of operating research reactors face challenges due to the negative impacts of component and system ageing, which manifest in a number of forms. This situation was highlighted by a serious medical isotope supply crisis which peaked in mid-2010, when several major producing reactors underwent prolonged shutdowns due to extensive necessary overhauls of various systems. Several facilities have established a proactive systematic approach to managing ageing or mitigating its impact on safety and availability of isotopes. Others have tried to prevent or remedy the drawbacks of ageing on a case by case basis. Overall, a large body of knowledge related to ageing issues exists in many Member States. Collecting and sharing this information within the research reactor community can provide a solid foundation to develop a more systematic approach — that is, an ageing management programme to prevent negative consequences of ageing on the safety, and the operability and lifetime of operating, or even future, reactors. It may also help organizations to manage research reactors that have been in an extended shutdown state by ensuring that any required systems are operated and maintained in a safe manner prior to final decommissioning and disposal of fuel to safe storage facilities. Sharing experiences from projects undertaken to refurbish or replace equipment and systems, satisfy safety and regulatory requirements, improve

    This is the third of a 3-part series presenting 2 effective applications--acuity and dosage--that describe how the business case for case management (CM) can be made. In Part I, dosage and acuity concepts were explained as client need-severity, CM intervention-intensity, and CM activity-dose prescribed by amount, frequency, duration, and breadth of activities. Concepts were presented that related the practice of CM to the use of evidence-based practice (EBP), knowledge, and methods and the development of instruments that measure and score pivotal CM actions. Part I also featured a specific exemplar, the CM Acuity Tool, and described how to use acuity to identify and score the complexity of a CM case. Part II further explained dosage and 2 acuity instruments, the Acuity Tool and AccuDiff. Part III presents linkage to EBP and practical applications. The information contained in the 3-part series applies to all CM practice settings and contains ideas and recommendations useful to CM generalists, specialists, supervisors, and business and outcomes managers. The Acuity Tools Project was developed from frontline CM practice in one large, national telephonic CM company. Dosage: A literature search failed to find research into dosage of a behavioral intervention. The Huber-Hall model was developed and tested in a longitudinal study of CM models in substance abuse treatment and reported in the literature. Acuity: A structured literature search and needs assessment launched the development of the suite of acuity tools. A gap analysis identified that an instrument to assign and measure case acuity specific to CM activities was needed. Clinical experts, quality specialists, and business analysts (n = 7) monitored the development and testing of the tools, acuity concepts, scores, differentials, and their operating principles and evaluated the validity of the acuity tools' content related to CM activities. During the pilot phase of development, interrater reliability testing of

    The questions attached to nuclear power plant (NPP) ageing and the need for monitoring and assessment of plant condition will grow in importance as more NPPs approach and pass the end of their nominal design lives. Ageing in nuclear plants must be effectively managed to ensure plant safety during their entire service life. This paper provides an overview of the IAEA programme and its results on the evaluation and management of safety aspects of NPP ageing. Under this programme, three generic guidance documents have been prepared on: data collection and record keeping; ageing management methodology; and the use of probabilistic safety assessment in plant life extension considerations. A two pronged strategy involving both technical and regulatory aspects has been adopted for the current and future work. (author)

    Asthma self-management education improves asthma-related outcomes. We conducted this analysis to evaluate variation in the percentages of adults with active asthma reporting components of asthma self-management education by age at asthma onset. Data from 2011 to 2012 Asthma Call-back Surveys were used to estimate percentages of adults with active asthma reporting six components of asthma self-management education. Components of asthma self-management education include having been taught to what to do during an asthma attack and receiving an asthma action plan. Differences in the percentages of adults reporting each component and the average number of components reported across categories of age at asthma onset were estimated using linear regression, adjusted for age, education, race/ethnicity, sex, smoking status, and years since asthma onset. Overall, an estimated 76.4% of adults with active asthma were taught what to do during an asthma attack and 28.7% reported receiving an asthma action plan. Percentages reporting each asthma self-management education component declined with increasing age at asthma onset. Compared with the referent group of adults whose asthma onset occurred at 5-14 years of age, the percentage of adults reporting being taught what to do during an asthma attack was 10% lower among those whose asthma onset occurred at 65-93 years of age (95% CI: -18.0, -2.5) and the average number of components reported decreased monotonically across categories of age at asthma onset of 35 years and older. Among adults with active asthma, reports of asthma self-management education decline with increasing age at asthma onset.

    This paper discusses an experience on ISI of the Kartini reactor heat exchanger, as part of the implementation of an ageing management programme. Kartini reactor is located in Yogyakarta, Indonesia. The heat exchanger was constructed for 250 kW capacity. The type of heat exchanger is shell with tube recirculation. Tube material is stainless steel 304, and the shell and baffle plate materials are carbon steel. The heat exchanger has 72 tubes, its outer and inner diameters respectively are 19 and 16 mm, and tube thickness is 1.5 mm. The aim of ISI was to obtain and evaluate the heat exchanger’s condition including the detection of any possible local tube thinning, pitting corrosion or gradual thinning, and determine whether any degradation or deterioration of the heat exchanger could have a significant impact to safety. The heat exchanger was inspected utilizing eddy current equipment in 2003 and 2006. Inspection results in 2003 determined that 12 heat exchanger tubes have a thinning degradation level ranging from 10% up to 60% of the outer diameter due to pitting corrosion. Deterioration of baffle plates has been linked to general corrosion attack. Inspection results in 2006 showed a consistent thinning degradation level with the previous inspection in 2003. So far heat exchanger performance is still satisfactory, as defined by the transfer of primary heat for a 2°C difference between inlet and outlet as required. (author)

A total of 41 anisometropic amblyopes aged > or =8 years were analysed. In six patients, best-corrected visual acuity (BCVA) of amblyopic eye improved more than two lines within 2 weeks of full-time spectacle wear. The remaining patients were assigned to perform part-time patching during out-of-school hours. Long-term results were assessed in patients who were observed over 1 year after the end of the treatment. Among 35 patients, four dropped out, refusing further treatment, and one changed to atropine penalisation. The part-time patching schedule was completed in 30 patients. 90% of patients (27/30) complied well. Mean BCVA in the amblyopic eye improved significantly (ppart-time occlusion treatment in school-aged amblyopes, which had been carried out after school hours, was successful and the effect was sustained in most cases.

    Finland has four nuclear reactors units in two power plants. The first unit started operation in 1977 and in the early 1980's all four units were in use. During the last few years the aging management of the Nuclear Power Plant's (NPP) concrete structures has grown an important issue because the existing structures are reaching the end of their licensed operating lifetime (about 40 years). Therefore the nuclear power companies are developing aging management systems to avoid premature degradation of NPP facilities and to be able to extend their operating lifetime. This paper is about the development of a computerized ageing management system for the nuclear power plants concrete structures. The computerized ageing management system is built upon central database and implementation applications. It will assist the personnel of power companies to implement the aging management activities at different phases of the lifetime of a power plant. It will provide systematic methods for planning, surveillance, inspection, monitoring, condition assessment, maintenance and repair of structures. (authors)

    Inspection and maintenance activities for air conditioning facilities within the plant are managed mainly for active facilities, and as the years of operation pass, a method for detecting in advance aging-related integrity problems of passive facilities and taking necessary measures against them is required. Therefore, this paper establishes a standard aging management guideline for air conditioning facilities by selecting systems for which those facilities are to be managed, analyzing degradation mechanisms and reviewing the current status of aging degradation management. According to the review of additional equipment-specific aging degradation mechanisms and the current status of management to apply the aging degradation program to air conditioning facilities, it has been found that internal and external visual inspection procedures for fans, dampers, coils, filters and housings have to be added. It has been confirmed that among additional equipment s, fire dampers, fan bearings and belts and air cleaning/conditioning units with charcoal filters do not require additional inspection as they are periodically inspected. It has been found, however, that air cleaning/conditioning units without charcoal filters are to be inspected along with fans, ducts and coils

    The political decision in Germany to shut-down operation of several Nuclear Power Reactors (NPP's) and to completely terminate the use of Nuclear Power in Germany by 2022 has extensive consequences in matters of the Aging Management. Physical conditions and presumed accident conditions are different for NPP's in power operation and for NPP's in shut-down operation and different aging effects have to be considered. Nevertheless aging management is still required considering the expected extensive time for shut-down operation in order to guarantee the safety functions and the use of qualified components with a sufficient and approved state. All current Aging Management requirements have to be fulfilled in the future as well without any restriction to ensure functionality, reliability and availability. However, it is expected that business management reasons will not allow realizing greater modifications or projects, e.g. exchange of analogue I and C technologies such as Limitations or Reactor Protection System with digital equipment. In the area of I and C which is characterized by many similar I and C-modules a change of strategy begins to emerge: the repair of discontinued modules within the plant under the owner's responsibility and the redesign of modules. Previously, we had reported on the establishment of a systematic Aging Management approach in order to identify aging processes and effects. Since two years the Aging management system has been installed in the NPPs and now we contribute our experience related to the practical handling, the performance and the results of these systems in German NPP's.

    Age-related degradation mechanisms of key components are subject to aging management review by utilities considering plant license renewal. The management of aging effects in PWR internals must be demonstrated as specified in the US NRC Standard Review. The US NRC staff has also issued a Generic Aging Lessons Learned (GALL) report that documents the staff's basis for determining when existing generic programs are adequate to manage aging without change and when existing generic programs should be augmented for license renewal. The EPRI Materials Reliability Program (MRP) has been conducting studies to develop technical bases and guidelines to support aging management of PWR internals, with a particular attention to utility License Renewal commitments. The strategic approach taken by the MRP includes: developing an overall aging management framework, defining degradation mechanism screening values, categorizing and ranking internals components based on screening, performing functionality analyses and safety evaluation, and developing inspection and evaluation guidelines associated with each category of components. Screening criteria are developed for the following potential internals degradation mechanisms: - Stress Corrosion Cracking [Excluding Irradiation Effects]; - Irradiation-Assisted Stress Corrosion Cracking; - Thermal Aging Embrittlement; - Irradiation Embrittlement; - Void Swelling; - Stress Relaxation and Creep [Irradiation-enhanced]; - Wear; - Fatigue. The ranking and categorization calls to bin internals components into four categories: - Category A: component items for which aging degradation significance is minimal and aging effects are below the screening criteria; - Category C: 'lead' component items for which aging degradation significance is high or moderate and aging effects are above screening levels; - Category B: component items above screening levels but are not 'lead' component items and aging degradation significance

    The aim of this study was to explore and enhance the understanding of how togetherness in everyday occupations is experienced and discussed among older adults. Focus-group discussions generated the data and a total of 12 participants, including six women and six men, divided into three groups, participated in this study. Analysis was performed using a grounded theory approach. The findings reflect how togetherness in everyday occupations can be comprehended as multifold transactional processes, emphasizing how an acted belonging was a situated experience connecting people and places through unfolding stories. The findings suggest that the process of meaning-making in ongoing life was closely associated with togetherness and was negotiated with others through shared culture and experiences. Togetherness meant being part of something in which the persons involved were contributing to each other in various ways. However, being part of togetherness was complicated, especially when the person's life situation was challenged in some way. It was apparent from the analysis that togetherness could not be taken for granted. Rather, the findings reflect how togetherness was created and maintained through an ongoing process of nurturing established relationships as well as creating something new around occupations with others.

    The concept of stressful cognitive dysfunction, which is under consideration in this review, allows picking out several therapeutic targets. The brain, immune and endocrine systems being the principal adaptive systems in the body permanently share information both in the form of neural impulses and soluble mediators. The CNS differs from other organs due to several peculiarities that affect local immune surveillance. The brain cells secluded from the blood flow by a specialized blood-brain-barrier (BBB) can endogenously express pro- and anti-inflammatory cytokines without the intervention of the immune system. In normal brain the cytokine signaling rather contributes to exclusive brain function (e.g. long-term potentiation, synaptic plasticity, adult neurogenesis) than serves as immune communicator. The stress of different origin increases the serum cytokine levels and disrupts BBB. As a result peripheral cytokines penetrate into the brain where they begin to perform new functions. Mass intrusion of biologically active peptides having a lot of specific targets alters the brain work that we can observe both in humans and in animal experiments. In addition owing to BBB disruption dendritic cells and T cells also penetrate into the brain where they take up a perivascular position. The changes observed in stressed subject may accumulate during repeated episodes of stress forming a picture typical of the aging brain. Moreover long-term stress as well as physiological aging result in hormonal and immunological disturbances including hypothalamic-pituitary-adrenal axis depletion, regulatory T-cell accumulation and dehydroepiandrosterone decrease.

    Meissner, Ellen; Radford, Katrina

    2015-09-01

    This study examined the importance and performance of middle managers' skills to provide a starting point for a sector-wide leadership and management framework. There is an increasing consensus that the quality of management, leadership and performance of any organisation is directly linked to the capabilities of its middle managers and the preparation and on-going training they receive. A total of 199 middle managers from three aged care organisations in Australia participated in a questionnaire conducted during 2010-2011. This study found that middle managers perceived the need to develop their communication skills, self-awareness, change management, conflict resolution and leadership skills. Middle managers perceive a discrepancy between performance and importance of various managerial skills. This study demonstrated that provision of training needs to go beyond clinical skills development and further investigation into managers' needs is necessary, particularly considering the diversity of this critical group in organisations. Future training opportunities provided to middle managers need to address the 'softer' skills (e.g. communication) rather than 'technical' skills (e.g. clinical skills). The provision of training in these skills may improve their performance, which may also lead to increased job satisfaction, continuity in leadership and management and ultimately improvements in the quality of care provided. © 2014 John Wiley & Sons Ltd.

    2010-06-01

    Physician productivity disparities are not uncommonly debated within radiology groups, sometimes in a contentious manner. Attempts to measure productivity, identify and motivate outliers, and develop equitable management policies can present challenges to private and academic practices alike but are often necessary for a variety of professional, financial, and personnel reasons. This is the first of a two-part series that will detail metrics for evaluating radiologist productivity and review published benchmarks, focusing primarily on clinical work. Issues and limitations that may prevent successful implementation of measurement systems are explored. Part 2 will expand that discussion to evaluating nonclinical administrative and academic activities, outlining advantages and disadvantages of addressing differential productivity, and introducing potential models for practices seeking to motivate physicians on the basis of both clinical and nonclinical work.

  11. Metabolic syndrome and hypertension: regular exercise as part of lifestyle management.

    2014-11-01

    The incorporation of physical activity and exercise represents a clinically important aspect in the management of metabolic syndrome, hypertension, and diabetes. While the benefit of exercise and active lifestyles is well documented for prevention and risk reduction of cardiovascular and stroke outcomes, the detailed regiment and recommendations are less clear. The components of a prescribed physical activity include consideration of activity type, frequency of an activity, activity duration, and intensity of a specific physical movement. The exercise parameters prescribed as part of the management of metabolic syndrome, diabetes, and elevated blood pressure are most often proposed as separate documents while the general recommendations are similar. The evidence is strong such that physical activity and exercise recommendations in disease management guidelines are considered high quality. The general recommendations for both blood pressure and glycemic management include a regiment of physical activity with moderate- to high-intensity exercise of 30-min bouts on multiple days with a desired goal of a total of 150 min of exercise per week. While additional research is needed to identify the specific exercise/activity mode, frequencies for exercise training, intensity levels, and duration of exercise that achieve maximal blood pressure and glycemic lowering, this general recommendation showed a consistent and significant benefit in risk reduction. Similarly, the current available evidence also indicates that aerobic exercise, dynamic resistance exercise, and isometric exercises can lower blood pressure and improve glycemic control.

    2006-01-01

    The activity evaluation of the Ulsan fault system (UFS) based on marine terrace age study in the southeastern part of Korean peninsula has been carried out. (1) The marine terrace distribution map along the southeastern coast of Korean peninsula has been distributed three wide terraces and several sub-terraces. The age of the above three terraces was determined by the discovery of wide tephras to be MIS5e, 7 and 9 from the lowest, respectively. (2) The active fault map along UFS was constructed. There will be the possibility that the UFS will be divided into three segments by the feature of lineaments. (3) The fault bounds between mountain at the eastern side, and plain at the western side in the most part of fault. It is interpreted that the UFS builds up the eastern mountain as a reverse movement fault. The latest activity of this fault system was clarified at the two localities by outcrop and trench investigation. The latest activity at Galgok-ri located in the northern part of the fault was occurred between 2,840 and 1,440 yBP. It was found to be between 7,470 and 2,990 yBP at Gaegok-ri, located in the central part of the fault. The latest activity at the Wangsan, which is between Galgok-ri and Gaegok-ri, was older than 7,000 yBP. The latest activity of the UFS differs between studied points. (4) The vertical slip rate of the UFS was calculated from the amount of vertical deformation and the age of terraces. Its range was between several cm to 20 cm in the 1000 years. This value corresponds to lower B and C class activity defined in Japan. (author)

    1990-01-01

    Research into the reproductive efficiency of Nganda cattle was carried out in a study with two separate parts. The aim of the first part of the study was to determine whether delayed puberty was a serious problem in Nganda heifers. Sixty Nganda heifers and their crosses with the other local types were monitored for ovarian activity to establish their cyclicity. The results indicated that over 50% started cycling at about 2.5 years of age; nearly 90% of the heifers had started sexual activity by 3 years of age. To test whether the age at puberty could be reduced by supplementary feeding and control of internal and external parasites, 20 Nganda heifers 1.5 years old were selected in the second part of the study. The results proved that supplementary feeding, deworming and spraying against ectoparasites had a positive influence on the initiation of sexual activity in pubertal Nganda heifers.

    2009-01-01

    This case study describes a quality initiative to minimize restraint in an Australian residential aged care facility. The process of improving practice is examined with reference to the literature on implementation of research into practice and change management. The differences between planned and emergent approaches to change management are discussed. The concepts of resistance and attractors are explored in relation to our experiences of managing the change process in this initiative. The importance of the interpersonal interactions that were involved in facilitating the change process is highlighted. Recommendations are offered for dealing with change management processes in clinical environments, particularly the need to move beyond an individual mind-set to a systems-based approach for quality initiatives in residential aged care.

    2015-01-01

    As attentions to the beyond design basis accident have increased following Fukushima accident, the importance of aging management for key system, structure and components of nuclear power plant (NPP) also has been emerged as the key factor for safety and reliability of NPPs. The diverse experiences can serve as the foundation for aging management processes that has major trust in the understanding of materials degradation mechanisms. IAEA and IFRAM have collaborated to produce the nuclear plant aging management handbook in order to help entry-level engineers and graduate students understand big pictures. As the number of old NPPs and new-comer countries have increased, sharing experiences and accumulated knowledge from existing nuclear industries has become increasingly important. From this point of view, the handbook has been completed for publication by IAEA which assembled a panel of international experts to integrate the vast body of background knowledge regarding aging mechanism and the extensive know-hows of expertsinto a primer handbook. The next step is to actively utilize the IAEA handbook to produce its web version. In order to reach the ultimate purpose of nuclear safety culture of IAEA, information the handbook should be made easily accessible ana understandable. In this regards, the conversion of IFRAM handbook to web version is being planned. Careful considerations about how to restructure the content and how to reflect opinions from experts and readers are needed. In addition, this handbook can be extended to a training program for maintenance managers, vendors, research organizations and regulators to assist them in their work on aging management in operating NPPs. Through these two aspects, this IFRAM handbook on aging management of NPPs will support of NPP staff both new-comer and established countries. This paper introduces the purpose, approach, structure, content of already completed IAEA handbook and the status and plan for IFRAM Web

    The Hoshino gold area is located in the western part of the Hohi volcanic zone, northern Kyushu. Volcanic rocks in this area vary from andesitic rocks in the north to dacite and rhyolite in the South. The basement is constituted by metamorphic rocks of pre-Cretaceous age. The volcanic rocks of Pliocene age were subdivided into eight volcanic units. Seven fission track ages of zircons from five volcanic units have been determined, using the external detector method. The age data obtained, combined with some previously reported ages, show that two main volcanic activities have occurred in the area. The first volcanic activity took place around 4.3 Ma, and resulted into the deposition of the Hoshino Andesite and the Ikenoyama Conglomerate. The second main volcanism started around 3.5 Ma, and was characterized by the eruption of the Shakadake Andesite and the Reiganji Andesite at the early stage, then, by more acidic rocks of the Takeyama Andesite, the Hyugami Dacite and the Kuroki Rhyolite at the later stage. The main volcanism in the area ceased around 2.6 Ma. (author)

    A plant's maintenance program is the principal vehicle through which age-related degradation is managed. From 1988 to 1991, the NRC evaluated the maintenance program of every nuclear power plant in the United States. Forty-four out of a total of sixty-seven of the reports issued on these in-depth team inspections have been reviewed for insights into the strengths and weaknesses of the programs as related to the need to understand and manage the effects of aging on nuclear plant structures, systems, and components (SSCs). Relevant information has been extracted from these inspection reports sorted into several categories; including Specific Aging Insights, Preventive Maintenance, Predictive Maintenance and Condition Monitoring, Post Maintenance Testing, Failure Trending, Root Cause Analysis and Usage of Probabilistic Risk Assessment in the Maintenance Process. Specific examples of inspection and monitoring techniques successfully used by utilities to detect degradation due to aging have been identified

  3. Data collection and record keeping for the management of nuclear power plant ageing: A safety practice

    International Nuclear Information System (INIS)

    1991-01-01

    This Safety Practice is the first in a series of reports under the programme on the management of nuclear power plant ageing. The purpose of the programme is to facilitate the exchange of information and to promote co-operation among Member States towards understanding and managing the ageing degradation of components, with the aim of maintaining safe and reliable plant operation. The availability and evaluation of appropriate data on nuclear power plant components are essential to safety and constitute a key factor in plant life extension considerations. The present publication provides guidance on data requirements and an effective and practical system for data collection and record keeping in relation to the evaluation and management of ageing and service life. This guidance is based on current practices. It is envisaged that the application of the guidance will contribute to the safe and reliable operation of nuclear power plants and will facilitate international information exchange on ageing related component failures, malfunctions and degradation, since data collected using the same ground rules would be easier to exchange and compare. The guidance is intended primarily for the management, maintenance and technical staff of nuclear power plants, on whom the ultimate success of the recommended system and its associated benefits depend. Intended secondary audiences include utility management and central technical support organizations, regulatory bodies, standards organizations, design companies, and research and development institutes. 8 refs, 1 fig., 1 tab

    Emergency managers must be able to think critically in order to identify and anticipate situations, solve problems, make judgements and decisions effectively and efficiently, and assume and manage risk. Heretofore, a critical thinking skills assessment of local emergency managers had yet to be conducted that tested for correlations among age, gender, education, and years in occupation. An exploratory descriptive research design, using the Watson-Glaser Critical Thinking Appraisal-Short Form (WGCTA-S), was employed to determine the extent to which a sample of 54 local emergency managers demonstrated the critical thinking skills associated with the ability to assume and manage risk as compared to the critical thinking scores of a group of 4,790 peer-level managers drawn from an archival WGCTA-S database. This exploratory design suggests that the local emergency managers, surveyed in this study, had lower WGCTA-S critical thinking scores than their equivalents in the archival database with the exception of those in the high education and high experience group. © 2013 The Author(s).

    Full Text Available Objective: The aim of the present study was to evaluate the effect of age, sex, location and management on cattle mortality rate in Rajshahi division of Bangladesh. Materials and methods: The study was conducted in 8 districts of Rajshahi division during July 2011 to June 2012. A total of 17,982 cattle heads were investigated based on age, sex, area. Data were collected from the cattle owners using a closed structured questionnaire. Tentative cause of cattle mortality was identified based on clinical signs, laboratory tests, history, ante-mortem and postmortem reports. Management practices of the cattle were also investigated. Results: Out of 17,982 cattle heads, 549 were found to be dead by various diseases, and an average mortality rate was 3.05%. Age-wise mortality rate of cattle revealed that the maximum mortality rate was found in the age group of 0.05 between the cattle mortality rate in Natore district (2.84% and Joypurhat districts (2.84%. Conclusion: The overall mortality rate of cattle in Rajshahi division was found comparatively low. This might be due to improved management practices, better veterinary services, and awareness among farmers. However, cattle mortality rate in the age group <2-year is alarming due to bad management practices and disease. [J Adv Vet Anim Res 2016; 3(1.000: 13-17

    Hashemian, H.M.

    2010-01-01

    Pressure to improve plant efficiency and maximize safety and the increasing age of existing NPPs are forcing the global nuclear power industry to confront the challenges of aging - caused by stressors such as temperature, humidity, radiation, electricity, and vibration - in key instrument and control (I and C) components like pressure transmitters, temperature sensors, neutron detectors, and cables. Traditional aging management methods, such as equipment replacement, required the process to be shut down. Recent aging management technologies, collectively known as online monitoring (OLM), enable plants to monitor the condition and aging of their installed I and C while the plant is operating. Developed through R and D initiatives worldwide, such OLM techniques include low- and high-frequency methods that use existing sensors, such as noise analysis; methods based on test or diagnostic sensors, such as for vibration-measuring accelerometers; and methods, such as the power interrupt (PI) test, based on active measurements made by injecting a test signal into the component under test. A review of these aging management methods, their effectiveness, and their interrelation provides a foundation for understanding the next stage in the evolution of OLM: truly integrated hybrid OLM systems capable of robust condition monitoring in both novel and familiar operating conditions.

    Eight percent of Australians aged 65 years and over receive residential aged care each year. Residents are increasingly older, frailer and have complex care needs on entry to residential aged care. Up to 63% of Australian residents of aged care facilities take nine or more medications regularly. Together, these factors place residents at high risk of adverse drug events. This paper reviews medication-related policies, practices and research in Australian residential aged care. Complex processes underpin prescribing, supply and administration of medications in aged care facilities. A broad range of policies and resources are available to assist health professionals, aged care facilities and residents to optimise medication management. These include national guiding principles, a standardised national medication chart, clinical medication reviews and facility accreditation standards. Recent Australian interventions have improved medication use in residential aged care facilities. Generating evidence for prescribing and deprescribing that is specific to residential aged care, health workforce reform, medication-related quality indicators and inter-professional education in aged care are important steps toward optimising medication use in this setting.

    This is the second of two papers reporting the results of a major study considering 'operator models' for municipal solid waste management (MSWM) in emerging and developing countries. Part A documents the evidence base, while Part B presents a four-step decision support system for selecting an appropriate operator model in a particular local situation. Step 1 focuses on understanding local problems and framework conditions; Step 2 on formulating and prioritising local objectives; and Step 3 on assessing capacities and conditions, and thus identifying strengths and weaknesses, which underpin selection of the operator model. Step 4A addresses three generic questions, including public versus private operation, inter-municipal co-operation and integration of services. For steps 1-4A, checklists have been developed as decision support tools. Step 4B helps choose locally appropriate models from an evidence-based set of 42 common operator models ( coms); decision support tools here are a detailed catalogue of the coms, setting out advantages and disadvantages of each, and a decision-making flowchart. The decision-making process is iterative, repeating steps 2-4 as required. The advantages of a more formal process include avoiding pre-selection of a particular com known to and favoured by one decision maker, and also its assistance in identifying the possible weaknesses and aspects to consider in the selection and design of operator models. To make the best of whichever operator models are selected, key issues which need to be addressed include the capacity of the public authority as 'client', management in general and financial management in particular.

    Delirium is associated with poor outcomes following acute hospitalization. A specialized delirium management unit, the Geriatric Monitoring Unit (GMU), was established. Evening bright light therapy (2000-3000 lux; 6-10 pm daily) was added as adjunctive treatment, to consolidate circadian activity rhythms and improve sleep. This study examined whether the GMU program improved sleep, cognitive, and functional outcomes in delirious patients. A total of 228 patients (mean age = 84.2 years) were studied. The clinical characteristics, delirium duration, delirium subtype, Delirium Rating Score (DRS), cognitive status (Chinese Mini-Mental State Examination), functional status (modified Barthel Index [MBI]), and chemical restraint use during the initial and predischarge phase of the patient's GMU admission were obtained. Nurses completed hourly 24-hour patient sleep logs, and from these, the mean total sleep time, number of awakenings, and sleep bouts (SB) were computed. The mean delirium duration was 6.7 ± 4.6 days. Analysis of the delirium subtypes showed that 18.4% had hypoactive delirium, 30.2% mixed delirium, and 51.3% had hyperactive delirium. There were significant improvements in MBI scores, especially for the hyperactive and mixed delirium subtypes (P hours) (P hours) (P bright light therapy as part of a multicomponent delirium management program. The benefits appear to have occurred mainly in patients with hyperactive delirium, which merits further in-depth, randomized controlled studies.

    Operational experience shows that excellent plant safety and excellent performance go hand in hand, and that they are achieved by effective leadership and management that includes a unified approach to safety and production. This is also applicable to ageing management. Effective ageing management leads to both enhanced plant safety and enhanced performance and is a prerequisite for long service life. The IAEA project on Safety Aspects of NPP Ageing has produced since 1990 a comprehensive set of programmatic and component specific guidelines on managing ageing, while providing an interactive environment for information exchange and co-operation among practitioners, and has assisted Member States in the application of the guidelines through the provision of training and advice. The objective of the CD-ROM is to preserve the IAEA's guidance on ageing management and to facilitate its retrieval, updating, extension and dissemination in order to help increase the effectiveness of ageing management at nuclear power plants

    2010-07-01

    Team performance has been studied in many safety-critical organizations including aviation, nuclear power plant, offshore oil platforms and health organizations. This study looks into teamwork strategies that air traffic controllers employ to manage emergencies and abnormal situations. Two field studies were carried out in the form of observations of simulator training in emergency and unusual scenarios of novices and experienced controllers. Teamwork strategies covered aspects of team orientation and coordination, information exchange, change management and error handling. Several performance metrics were used to rate the efficiency of teamwork and test the construct validity of a prototype model of teamwork. This is a companion study to an earlier investigation of taskwork strategies in the same field (part I) and contributes to the development of a generic model for Taskwork and Teamwork strategies in Emergencies in Air traffic Management (T(2)EAM). Suggestions are made on how to use T(2)EAM to develop training programs, assess team performance and improve mishap investigations. Copyright 2010 Elsevier Ltd. All rights reserved.

    The paper reviews the existing generic aging management programs (AMPs) for the reactor coolant system (RCS) components in boiling water reactors (BWRs), including the reactor pressure vessel and internals, the reactor recirculation system, and the connected piping. These programs have been evaluated in the U.S. Nuclear Regulatory Commission (NRC) report, Generic Aging Lessons Learned (GALL), NUREG-1801, for their use in the license renewal process to manage several aging effects, including loss of material, crack initiation and growth, loss of fracture toughness, loss of preload, wall thinning, and cumulative fatigue damage. The program evaluation includes a review of ten attributes (scope of program, preventive actions, parameters monitored/inspected, detection of aging effects, monitoring and trending, acceptance criteria, corrective actions, confirmative process, administrative control, and operating experience) for their effectiveness in managing a specific aging effect in a given component(s). The generic programs are based on the ASME Section XI inservice inspection requirements; industry guidelines for inspection and evaluation of aging effects in BWR reactor vessel, internals, and recirculation piping; monitoring and control of BWR water chemistry; and operating experience as reported in the USNRC generic communications and industry reports. The review concludes that all generic AMPs are acceptable for managing aging effects in BWR RCS components during an extended period of operation and do not need further evaluation. However, the plant-specific programs for managing aging in certain RCS components during an extended period of operation do require further evaluation. For some plant-specific AMPs, the GALL report recommends an aging management activity to verify their effectiveness. An example of such an activity is a one-time inspection of Class 1 small-bore piping to ensure that service-induced weld cracking is not occurring in the piping. Several of

    Self-management is a critical dimension in managing chronic conditions, particularly in heart failure (HF). Knowledge, attitudes and beliefs, relating to both illness and wellness, are strongly influenced by culture and ethnicity, impacting upon an individual's capacity to engage in self-care behaviours. Effective management of HF is largely dependent on facilitation of culturally informed, self-care behaviours to increase adherence to both pharmacological and non-pharmacological strategies. The Understanding the cultural experiences of individuals with chronic heart failure (CHF) in South East Health (DISCOVER) study is an exploratory, observational study investigating health patterns, information needs and the adjustment process for overseas-born people with HF living in Australia. An integrative literature review was augmented by qualitative data derived from key informant interviews, focus groups and individual interviews. A key finding of this study is that culture provides an important context to aid interpretations of attitudes, values, beliefs and behaviours, not only in illness but in health. While individual differences in attitudes and beliefs were observed among participants, common themes and issues were identified across cultural groups. Data from the DISCOVER study revealed the primacy of family and kinship ties. These relationships were important in making decisions about treatment choices and care plans. Participants also revealed the critical role of the 'family doctor' in assisting people and their families in brokering the health care system. In this study, heart disease was considered to be a significant condition but cancer was the condition that people both feared and dreaded the most, despite the high mortality rates of HF. This sample reported that religious and traditional beliefs became more important as people aged and considered their mortality. As HF is predominately a condition of ageing, the information derived from this study will

    1997-01-01

    Objective: To review the approach to the diagnosis, classification, assessment, treatment and continuing management of patients with non-Hodgkin's lymphoma with an emphasis on the role of radiation therapy and the management of localized disease. Non-Hodgkin's lymphomas are a diverse group of diseases with an age standardized incidence of approximately 17 per 100,000 population. They become more common with increasing age and frequently involve extranodal sites. A number of potential etiological causes have been defined e.g. congenital and acquired immunodeficiency states, viruses, ionizing radiation, chronic inflammatory diseases and environmental toxins. Management is most influenced by the histological type of lymphoma. Numerous classifications have derived from architectural and cytological observations (Rappaport), concepts involving morphologic and phenotypic characterization of lineage and differentiation (Lukes-Collins, Kiel), and grade in the context of cytological differentiation and prognosis (Working Formulation). The introduction of the REAL classification has characterized clinico-pathological entities within a B-cell, T-cell and Hodgkin's disease framework, and recognized histopathologic grade as a variable within each category. The utility of this approach is likely to increase as disease entities become further defined through karyotypic and genotypic characterization. Stage is the other principal determinant of management. Whilst the Ann Arbor staging classification is employed routinely, its limitations in the context of extranodal disease, characterization of local disease extent and bulk have resulted in the incorporation of additional prognostic factors into management policies. Important prognostic factors include patient-related variables (age, performance status), disease-related attributes (bulk, number of involved nodes, B-symptoms) and biological attributes (LDH, ESR, β-2 macroglobulin, soluble CD-30, proliferation indices).

    To determine the outcome of part-time occlusion therapy in children with anisometropic amblyopia detected after they were 8 years of age. We analyzed 29 eyes with anisometropic amblyopia in children 8 years of age and older. The mean age was 8.79 +/- 0.98 (range 8-12) years old. The subjects whose best-corrected visual acuity (BCVA) did not improve by two lines or better within 2 weeks of wearing glasses full-time were prescribed occlusion therapy for 6 hours a day outside of school hours, along with the instruction to wear glasses full-time. Subjects who complied with occlusion for more than 3 hours a day were considered to comply well. The major component of the anisometropia was hyperopia in 51.7% of the subjects, and hyperopia plus astigmatism was found in 24.1%. The mean pretreatment BCVA score was 0.51 0.23 (LogMAR). Compliance was 89.66%. The mean posttreatment BCVA was 0.03 +/- 0.01 (LogMAR), and the success rate, based on a posttreatment BCVA of 0.1 (LogMAR) and better, was 96.43%. It took an average of 4.79 +/- 3.35 months to reach the desired posttreatment BCVA. The mean posttreatment stereopsis was 79.78 +/- 37.61 seconds of arc. The recurrence rate was 8%. The visual improvement was related to the degree of compliance (p = 0.000). The time taken to reach the posttreatment BCVA was shorter in subjects with a better pretreatment BCVA (p = 0.019), but it did not relate to the compliance (p = 0.366). The most common component of anisometropia detected after 8 years of age was hyperopia. The part-time occlusion therapy, which had been carried out after school hours, was successful in most cases.

    Burnay, S.G.; Simola, K.; Kossilov, A.; Pachner, J.

    1993-01-01

    This paper describes pilot studies which have been implemented to study the aging behavior of safety related component parts of nuclear power plants. In 1989 the IAEA initiated work on pilot studies related to the aging of such components. Four components were identified for study. They are the primary nozzle of a reactor vessel; a motor operated isolating valve; the concrete containment building; and instrumentation and control cables within the containment facility. The study was begun with phase 1 efforts directed toward understanding the aging process, and methods for monitoring and minimizing the effects of aging. Phase 2 efforts are directed toward aging studies, documentation of the ideas put forward, and research to answer questions identified in phase 1. This paper describes progress made on two of these components, namely the motor operated isolation valves, and in-containment I ampersand C cables

    Werry, E.V.

    1990-10-01

    This report comprises Volume 1 of a review of US nuclear plant regulatory instruments to determine the amount and kind of information they contain on managing the aging of safety-related components in US nuclear power plants. The review was conducted for the US Nuclear Regulatory Commission (NRC) by the Pacific Northwest Laboratory (PNL) under the NRC Nuclear Plant Aging Research (NPAR) Program. Eight selected regulatory instruments, e.g., NRC Regulatory Guides and the Code of Federal Regulations, were reviewed for safety-related information on five selected components: reactor pressure vessels, steam generators, primary piping, pressurizers, and emergency diesel generators. Volume 2 will be concluded in FY 1991 and will also cover selected major safety-related components, e.g., pumps, valves and cables. The focus of the review was on 26 NPAR-defined safety-related aging issues, including examination, inspection, and maintenance and repair; excessive/harsh testing; and irradiation embrittlement. The major conclusion of the review is that safety-related regulatory instruments do provide implicit guidance for aging management, but include little explicit guidance. The major recommendation is that the instruments be revised or augmented to explicitly address the management of aging

    2010-01-01

    Maintenance and enhancement of the availability and safety of fossil-fired and nuclear power plants currently in operation are increasing in importance with plants' age. The paper deals with issues related to e.g. the operation of C and I-systems at the end of production and with the challenges involved in their replacement during plant operation and describes the various measures taken for monitoring electrical equipment. Taking the improvement of the existing protection systems against internal arcs in electrical bus bars as an example, practical approaches for ageing management are described. In addition, the strategic approaches will be explained that were developed within a VGB working group due to the introduction of a new regulation on ageing management in nuclear power plants.

    The Nuclear Regulatory Authority (tentativename) will be established under the Ministry of Environment, aiming at independent regulatory decision making. Limit of operation to 40 years will be regulated. As an exception, extension of a certain period (<20 years) will be approved only one time when compliance with the regulatory standards is confirmed. It is necessary on a technical information basis to check and evaluate the utilities' activities of the ageing management technical evaluation by the new regulatory organization. Technical information and knowledge-bases for the design, construction, operation and maintenance of nuclear power plants should be utilized comprehensively not only for utilities but also for the regulatory orgnazation. Obsolesce of codes and standards may bring weakness in defense in depth, or higher core damage frequency. Investigation of the aged and thermal material is effective for proactive management and sophistication of codes and standards for ageing managementoflong term operation. (author)

    There are 55 operating commercial light water reactor plants (32 BWRs and 23 PWRs) in Japan. Twelve (12) plants have been operating for more than 30 years. Utility companies are required to perform an 'Ageing Management Technical Assessment' be-fore the end of 30 years operation of each plant. The assessments for each plant have been evaluated by the Nuclear and Industry Safety Agency (NISA) of the Ministry of Economy Trade and Industry (WTI) for these 12 plants. The Japan Nuclear Energy Safety Organisation (JNES) has compiled Technical Review Manuals for six major degradation phenomena for the evaluation of Ageing Management Technical Assessment. A 'Road-map for Ageing and Plant Life Management' was established in 2005 by the Special Committee in the Atomic Energy Society of Japan under the commission from the JNES. Within the framework of the road-map, the major research and development fields are divided into the following four categories: 1) engineering information systems; 2) research and development of technologies for inspection, evaluation and repair of the components and materials; 3) development of codes and standards; 4) synthesised maintenance engineering. Continuous revision of the 'Strategy Maps for Ageing Management and Safe Long-term Operation' has been performed under the Coordinating Committee of Ageing Management to promote research and development activities by industries, government and academia, effectively and efficiently. Systematic development of the information basis for database and knowledge-base has been undertaken in addition to the development of codes and standards by academic societies through intensive domestic safety research collaborations and international collaboration.

  20. Multi-aged Forest: an Optimal Management Strategy for Carbon Sequestration

    Science.gov (United States)

    Yao, L.; Tang, X.; Ma, M.

    2017-12-01

    Disturbances and climatic changes significantly affect forest ecosystem productivity, water use efficiency (WUE) and carbon (C) flux dynamics. A deep understanding of terrestrial feedbacks to such effects and recovery mechanisms in forests across contrasting climatic regimes is essential to predict future regional/global C and water budgets, which are also closely related to the potential forest management decisions. However, the resilience of multi-aged and even-aged forests to disturbances has been debated for more than 60 years because of technical measurement constraints. Here we evaluated 62 site-years of eddy covariance measurements of net ecosystem production (NEP), evapotranspiration (ET), the estimates of gross primary productivity (GPP), ecosystem respiration (Re) and ecosystem-level WUE, as well as the relationships with environmental controls in three chronosequences of multi- and even-aged coniferous forests covering the Mediterranean, temperate and boreal regions. Age-specific dynamics in multi-year mean annual NEP and WUE revealed that forest age is a key variable that determines the sign and magnitude of recovering forest C source-sink strength from disturbances. However, the trends of annual NEP and WUE across succession stages between two stand structures differed substantially. The successional patterns of NEP exhibited an inverted-U trend with age at the two even-aged chronosequences, whereas NEP of the multi-aged chronosequence increased steadily through time. Meanwhile, site-level WUE of even-aged forests decreased gradually from young to mature, whereas an apparent increase occurred for the same forest age in multi-aged stands. Compared with even-aged forests, multi-aged forests sequestered more CO2 with forest age and maintained a relatively higher WUE in the later succession periods. With regard to the available flux measurements in this study, these behaviors are independent of tree species, stand ages and climate conditions . We also
