    The successful implementations of the NATO-ASTECMATRIX project in Armenia are essential contribution into security, stability and solidarity among regional nations, by applying the best technical expertise to problem solving. Collaboration, networking and capacity-building are means used to accomplish these goals. A further aim is to promote the co-operation with new partners and the ASTEC are creating links between scientists and organizations in formerly separated communities, developing new strategy concentrating support on security related collaborative projects and finding answers to critical questions and a way of connecting nations. The NATO-ASTECMATRIX within Armenia leads to a network of high standards laboratories that will drastically improve the overview and the technical infrastructure for monitoring, accounting and control of CBRN materials in the Armenia. This new infrastructure will enhance the exchange of information on this vital issue via the IRIS. In follow-up phases, it will also help to better define the needs and requirements for a policy to enhance legal tools for the management of these materials, and for the creation of one or several agencies aiming at dealing with wastes or no longer useful materials containing CBRN components in Armenia

    2007-01-01

    This report describes the motivation for and a strategy to enhance the NATO Research and Technology Organisation's (RTO) current space research effort to reflect NATO's growing military dependence on space systems. Such systems and services provided by these systems are critical elements of military operations. NATO uses space systems for operational planning and support, communication, radio navigation, multi-sensor and multi-domain demonstrations. Such systems are also used to promote regional stability. A quantitative analysis of work related to space in the NATO RTO showed that during the period of 1998 - 2004, 5% of the research pursued in the NATO RTO has been clearly focused on space applications. Challenging environmental and organizational barriers for increasing RTO space research were identified. In part, these include lack of sufficient space expertise representation on panels, the military sensitivity of space, current panel work loads and the need for specific technical recommendations from peers. A strategy for enhancing space research in the RTO is to create a limited-life Space Advisory Group (SAG) composed of Space Expert Consultants who are panel members with appropriate expertise and additional expertise from the nations. The SAG will recommend and find support in the nations for specific technical activities related to space in the areas of Space Science, Remote Sensing Data Analysis, Spacecraft Systems, Surveillance and Early Warning, Training and Simulation and Policy. An RTO Space Advisory Group will provide an organizational mechanism to gain recognition of RTO as a forum for trans-Atlantic defence space research and to enhance space research activities.

    Full Text Available There is a tight relationship between information assurance, the intelligence cycle and information superiority within NATO operations. The intelligence cycle has a discrete architecture and provides on-time and relevant intelligence products to the joint force commanders and to other authorized users in a specifi c joint area of operations. The intelligence cycle must follow the evolution of the operation. A permanent intelligence estimate will be performed during the military decision making process and operations execution. Information superiority is one of the most powerful intelligence cycle achievements. and decisively infuences the success of NATO joint operations. Information superiority must be preserved and enhanced through information assurance. Information assurance is an information operation that must be planned by the military in charge of operation security or by non-military experts, executed by all personnel during the entire intelligence cycle life time and employed during the planning and execution of NATO joint operations.

    1987-01-01

    This collection of papers is the result of a symposium sponsored by NATO's Defense Research Group Panel VIII in the Spring of 1985. The symposium came into being when it became obvious to the NATO countries that research, development and utilization of advanced technologies for training was the best means of increasing both training effectiveness and efficiency. This symposium was the second in a series of three devoted to training. The series was structured to cover all aspects of training. The first series addressed the value of training, the second one dealt with the application of training technologies and the third and last of the series focused on academic issues concerned with the effect of prior learning on subsequent learning. The fact that a major American publisher has determined that computer based instruction is the technology of greatest interest to the NATO community is not surprising. Advances in microprocessor technology have revolutionized both how and where we train. During this symposium t...

    Significant efforts are put into the assessment of the severe accident integral code ASTEC, jointly developed since several years by IRSN and GRS, either through comparison with results of the most important international experiments or through benchmarks with other severe accident simulation codes on plant applications. These efforts are done in first priority by the code developers’ organisations, IRSN and GRS, and also by numerous partners, in particular in the frame of the SARNET European network. The first version of the new series ASTEC V2 had been released in July 2009 to SARNET partners. Two subsequent V2.0 code revisions, including several modelling improvements, have been then released to the same partners, respectively in 2010 and 2011. This paper summarises first the approach of ASTEC validation vs. experiments, along with a description of the validation matrix, and presents then a few examples of applications of the ASTEC V2.0-rev1 version carried out in 2011 by the SARNET users. These calculation examples are selected in a way to cover diverse aspects of severe accident phenomenology, i.e. to cover both in-vessel and ex-vessel processes, in order to provide a good picture of the current ASTEC V2 capabilities. Finally, the main lessons drawn from this joint validation task are summarised, along with an evaluation of the current physical modelling relevance and thus an identification of the ASTEC V2.0 validity domain

    The ASTEC code development by IRSN and GRS is aimed to provide an integral code for the simulation of the whole course of severe accidents in Light-Water Reactors. ASTEC is a complex system of codes for reactor safety assessment. In this validation, only the thermal-hydraulic module of ASTEC code is used. ASTEC is a lumped-parameter code able to represent multi-compartment containments. It uses the following main elements: zones (compartments), junctions (liquids and atmospherics) and structures. The zones are connected by junctions and contain steam, water and non condensable gases. They exchange heat with structures by different heat transfer regimes: convection, radiation and condensation. This paper presents the validation of ASTEC V1.3 on the tests T9 and T9bis, of the PANDA OECD/SETH experimental program, investigating the impact of injection velocity and steam condensation on the plume shape and on the gas distribution. Dedicated meshes were developed to simulate the test facility with the two vessels DW1, DW2 and the interconnection pipe. The obtained numerical results are analyzed and compared to the experiments. The comparison shows a good agreement between experiments and calculations. (author)

    2011-01-01

    The integral code ASTEC (Accident Source Term Evaluation Code) commonly developed since 1996 by the French IRSN and the German GRS is a fast running programme, which allows the calculation of entire sequences of severe accidents (SA) in light water reactors from the initiating event up to the release of fission products into the environment, thereby covering all important in-vessel and containment phenomena. Thus, the main ASTEC application fields are intended to be accident sequence studies, uncertainty and sensitivity studies, probabilistic safety analysis level 2 as well as support to experiments. The modular structure of ASTEC allows running each module independently and separately, e.g. for separate effects analyses as well as a combination of multiple modules for coupled effects testing and integral analyses. Subject of this paper is an overview of the new V2 series of the ASTEC code system and presentation of exemplary results for the application to severe accidents sequences at PWRs. (orig.)

    Highlights: • Independent assessment of the ASTEC severe accident code vs. experiments is summarised. • Main remaining modelling issues and development perspectives are identified. • Independent assessment of ASTEC code at full scale conditions is described. • Main requirements to address BWR and PHWR types of reactors are identified. - Abstract: Among the 43 organisations which joined the SARNET2 FP7 project from 2009 to 2013, 31 have been involved in the activities on the ASTEC code. This paper presents a synthesis of the main achievements that have been obtained on the ASTEC V2 integral code, jointly developed by IRSN (France) and GRS (Germany), on development, validation vs. experimental data and applications at full scale conditions for both Gen.II and Gen.III plants. As to code development, while the current V2.0 series of ASTEC versions was continuously improved (elaboration and release by IRSN and GRS of three successive V2.0 revisions), IRSN and GRS have also intensively continued in parallel the elaboration of the second ASTEC V2 major version (version V2.1) to be delivered end of 2014. Regarding code validation vs. experiments, the partners have assessed the V2.0 version and subsequent revisions vs. more than 50 experiments; this extended assessment notably confirmed that most models are today close to the State of the Art, while it also corroborated the yet known key-topics on which modelling efforts should focus in priority. As to plant applications, the comparison of ASTEC results with other codes allows concluding on a globally good agreement for in-vessel and ex-vessel severe accident progression. As to ASTEC adaptations to BWR and PHWR, significant achievements have been obtained through the elaboration and integration in the future V2.1 version of dedicated core degradation models, notably to account for multi coolant flows

    The Advanced Research Institute (A.R. 1.) on "the efficiency of Manufacturing Systems" was held under the auspices of the NATO Special Programm~ Panel on Systems Science as a part of the NATO Science Committee's continuous effort to promote the advancement of science through international co-operation. Advanced Research Institutes are organised for the purpose of bringing together experts in a particular field of interest to identify and make known the present state of knowledge in that area and, through informed debate, to make recommendations for directions for future research that would benefit the community at large. To this end two kinds of contribution were obtained by invitation. There were those papers which were about the current state of work in the area of manufacturing systems and its organisation; in addition three theme papers were presented to provide a stimulus to the discussion in terms of ways of thinking, both about the area and about the kind of research needed.

    Research on light-water reactor severe accidents (SA) is still required in a limited number of areas in order to confirm accident-management plans. Thus, 49 European organizations have linked their SA research in a durable way through SARNET (Severe Accident Research and management NETwork), part of the European 6th Framework Programme. One goal of SARNET is to consolidate the integral code ASTEC (Accident Source Term Evaluation Code, developed by IRSN and GRS) as the European reference tool for safety studies; SARNET efforts include extending the application scope to reactor types other than PWR (including VVER) such as BWR and CANDU. ASTEC is used in IRSN's Probabilistic Safety Analysis level 2 of 900 MWe French PWRs. An earlier version of ASTEC's SOPHAEROS module, including improvements by AECL, is being validated as the Canadian Industry Standard Toolset code for FP-transport analysis in the CANDU Heat Transport System. Work with ASTEC has also been performed by Bhabha Atomic Research Centre, Mumbai, on IPHWR containment thermal hydraulics. (author)

    The objectives of the International Standard Problem no 44 was aerosol depletion behaviour under severe accident conditions in a LWR containment examined in the KAEVER test facility of Battelle (Germany). Nine organisations participated with 5 different codes in the ISP44, including a joint participation of GRS and IPSN with the integral code ASTEC (and in particular the CPA module) they have commonly developed. Five tests were selected from the KAEVER test matrix: K123, K148, K186 and K188 as open standard problems and the three-component test K187 as blind standard problem. All these tests were performed in supersaturated conditions and with slight fog formation, which are the most ambitious conditions for the coupled problem of thermal hydraulics and aerosol processes. The comparison between calculation and test showed a good agreement for all the tests with respect to the thermal-hydraulic conditions in the vessel, i.e. total pressure, atmosphere temperature, sump water and nitrogen mass, etc.... As for aerosol depletion, the ASTEC results were in a good overall agreement with the measured data. The code in particular predicted well the fast depletion of the hygroscopic and mixed aerosols and the slow depletion of insoluble silver aerosol. The important effects of bulk condensation, solubility and the Kelvin effect on the aerosol depletion were well predicted. However the code overestimation of steam condensation on hygroscopic aerosols in supersaturated conditions indicates that some slight improvements of the appropriate ASTEC models are needed in the future. In the final ISP44 workshop, the deviations of the ASTEC results with respect to the experiments were considered to be small compared to those of most other codes. (authors)

  14. Collection and sharing of medical information and medical intelligence (M2I) in NATO: a transversal survey.

    There is a requirement for adequate medical expertise to be available throughout the range of potential future operations involving members of the North Atlantic Treaty Organization (NATO). The aim of this study was to assess the collection and sharing of medical intelligence and medical information (M2I) by NATO Nations, Partner Nations and NATO Command Structure and NATO Force Structure Headquarters (NCS/NFS HQs). A transversal survey was conducted between December 2014 and March 2015 using a survey form on M2I sent to NATO Nations and Partnership for Peace (PfP) Nations as well as NCS/NFS HQs. Correctly completed responses were received from 15/40 (37.5%) of the possible NATO and PfP Nations (37.5%) and 7/8 (87.5%) of the NCS/NFS HQs (100.0%). Deficiencies in the collection of M2I data were found due to lack of specific doctrines, networks, tools, structures and organisation. The survey provided an indication even though the participation rate was low for Nations. Part of the problem is thought to be that medical information and medical intelligence often lie in different chains of command. Future directions for this research could include studying the possibilities of a new specific information technology (IT) system to collect and to share M2I. Collection and sharing of M2I within the NATO/PfP community requires facilitation in order to strengthen the basis for decision-making and force health protection. The development of a dedicated NATO IT system may be a precondition for the implementation of an efficient M2I network. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

    Schiller Mark

    2016-06-01

    Full Text Available Multinational Brigade Operations involving NATO and its European Partners are the norm in the post-Cold War Era. Commonplace today are Multinational Brigades, composed of staffs and subordinate units representing almost every NATO Country and Partner, participating in training exercises or actual operations in both the European and Southwest Asian Theatres. Leadership challenges are prevalent for the Multinational Brigade Commander and his staff, especially those challenges they face in achieving an effective level of brigade interoperability in order to conduct successful operations in NATO’s present and future operating environments. The purpose of this paper is twofold: to examine the major interoperability obstacles a multinational brigade commander and his staff are likely to encounter during the planning and execution of brigade operations; and, to recommend actions and measures a multinational brigade commander and his staff can implement to facilitate interoperability in a multinational brigade operating environment. Several key interoperability topics considered integral to effective multinational brigade operations will be examined and analysed to include understanding partner unit capabilities and limitations facilitated by an integration plan, appropriate command and support relationships, compatible communications, synchronized intelligence and information collection, establishing effective liaison, and fratricide prevention. The paper conclusion will urge for a NATO land brigade doctrine considering doctrine’s critical importance to effective brigade command and control interoperability and the expected missions a land brigade will encounter in future NATO operating environments as part of the NATO Very High Readiness Joint Task Force (VJTF.

    Downing, John P.; Bauer, Frank H.; Thorpe, Christopher J.

    1989-01-01

    The ASTEC (Analysis and Simulation Tools for Engineering Controls) software is under development at Goddard Space Flight Center (GSFC). The design goal is to provide a wide selection of controls analysis tools at the personal computer level, as well as the capability to upload compute-intensive jobs to a mainframe or supercomputer. The project is a follow-on to the INCA (INteractive Controls Analysis) program that has been developed at GSFC over the past five years. While ASTEC makes use of the algorithms and expertise developed for the INCA program, the user interface was redesigned to take advantage of the capabilities of the personal computer. The design philosophy and the current capabilities of the ASTEC software are described.

    International Nuclear Information System (INIS)

    Nowack, H.; Erdmann, W.; Reinke, N.

    2011-01-01

    The integral code ASTEC is jointly developed by IRSN (Institut de Radioprotection et de Surete Nucleaire, France) and GRS (Germany). Its main objective is to simulate severe accident scenarios in PWRs from the initiating event up to the release of radioactive material into the environment. This paper describes the ASTEC modeling approach and the nodalisation of a KONVOI type PWR as an application example. Results from an integral severe accident study are presented and shortcomings as well as advantages are outlined. As a conclusion, the applicability of ASTEC V2.0 for deterministic severe accident analyses used for PSA level 2 and Severe Accident Management studies will be assessed. (author)

  19. Validation of ASTEC V2 models for the behaviour of corium in the vessel lower head

    International Nuclear Information System (INIS)

    Carénini, L.; Fleurot, J.; Fichot, F.

    2014-01-01

    The paper is devoted to the presentation of validation cases carried out for the models describing the corium behaviour in the “lower plenum” of the reactor vessel implemented in the V2.0 version of the ASTEC integral code, jointly developed by IRSN (France) and GRS (Germany). In the ASTEC architecture, these models are grouped within the single ICARE module and they are all activated in typical accident scenarios. Therefore, it is important to check the validity of each individual model, as long as experiments are available for which a single physical process is involved. The results of ASTEC applications against the following experiments are presented: FARO (corium jet fragmentation), LIVE (heat transfer between a molten pool and the vessel), MASCA (separation and stratification of corium non miscible phases) and OLHF (mechanical failure of the vessel). Compared to the previous ASTEC V1.3 version, the validation matrix is extended. This work allows determining recommended values for some model parameters (e.g. debris particle size in the fragmentation model and criterion for debris bed liquefaction). Almost all the processes governing the corium behaviour, its thermal interaction with the vessel wall and the vessel failure are modelled in ASTEC and these models have been assessed individually with satisfactory results. The main uncertainties appear to be related to the calculation of transient evolutions

    Tarabelli, D.; Ratel, G.; Pelisson, R.; Guillard, G.; Barnak, M.; Matejovic, P.

    2009-01-01

    This paper summarizes the work done in the SARNET European Network of Excellence on Severe Accidents (6th Framework Programme of the European Commission) on the capability of the ASTEC code to simulate in-vessel corium retention (IVR). This code, jointly developed by the French Institut de Radioprotection et de Surete Nucleaire (IRSN) and the German Gesellschaft fuer Anlagen und Reaktorsicherheit mbH (GRS) for simulation of severe accidents, is now considered as the European reference simulation tool. First, the DIVA module of ASTEC code is briefly introduced. This module treats the core degradation and corium thermal behaviour, when relocated in the reactor lower head. Former ASTEC V1.2 version assumed a predefined stratified molten pool configuration with a metallic layer on the top of the volumetrically heated oxide pool. In order to reflect the results of the MASCA project, improved models that enable modelling of more general corium pool configurations were implemented by the CEA (France) into the DIVA module of the ASTEC V1.3 code. In parallel, the CEA was working on ASTEC modelling of the external reactor vessel cooling (ERVC). The capability of the ASTEC CESAR circuit thermal-hydraulics to simulate the ERVC was tested. The conclusions were that the CESAR module is capable of simulating this system although some numerical and physical instabilities can occur. Developments were then made on the coupling between both DIVA and CESAR modules in close collaboration with IRSN. In specific conditions, code oscillations remain and an analysis was made to reduce the numerical part of these oscillations. A comparison of CESAR results of the SULTAN experiments (CEA) showed an agreement on the pressure differences. The ASTEC V1.2 code version was applied to IVR simulation for VVER-440/V213 reactors assuming defined corium mass, composition and decay heat. The external cooling of reactor wall was simulated by applying imposed coolant temperature and heat transfer

    2005-01-01

    The main objective of the European Validation of the Integral Code ASTEC (EVITA) project is to distribute the severe accident integral code ASTEC to European partners in order to apply the validation strategy issued from the VASA project (4th EC FWP). Partners evaluate the code capability through validation on reference experiments and plant applications accounting for severe accident management measures, and compare results with reference codes. The basis version V0 of ASTEC (Accident Source Term Evaluation Code)-commonly developed and basically validated by GRS and IRSN-was made available in late 2000 for the EVITA partners on their individual platforms. Users' training was performed by IRSN and GRS. The code portability on different computers was checked to be correct. A 'hot line' assistance was installed continuously available for EVITA code users. The actual version V1 has been released to the EVITA partners end of June 2002. It allows to simulate the front-end phase by two new modules:- for reactor coolant system 2-phase simplified thermal hydraulics (5-equation approach) during both front-end and core degradation phases; - for core degradation, based on structure and main models of ICARE2 (IRSN) reference mechanistic code for core degradation and on other simplified models. Next priorities are clearly identified: code consolidation in order to increase the robustness, extension of all plant applications beyond the vessel lower head failure and coupling with fission product modules, and continuous improvements of users' tools. As EVITA has very successfully made the first step into the intention to provide end-users (like utilities, vendors and licensing authorities) with a well validated European integral code for the simulation of severe accidents in NPPs, the EVITA partners strongly recommend to continue validation, benchmarking and application of ASTEC. This work will continue in Severe Accident Research Network (SARNET) in the 6th Framework Programme

    The objective of this paper is to present the results obtained from performing the calculations with ASTEC computer code for the Source Term evaluation for specific severe accident transient. The calculations have been performed with the new version of ASTEC. The ASTEC 1.3 R2 code version is released by the French IRSN (Institut de Radioprotection at de surete nucleaire) by the end of 2007. The sequences include the release of fission products into the reactor containment and environment and transport of fission products. The analyses proposed here are performed to simulate radioactive products release through the cold leg of SG under accidental conditions. This investigation has been performed in the framework of the SARNET project (under the EURATOM 6th framework program) by the FoBAUs group (Forum of Bulgarian ASTEC users). (authors)

    Since the beginning of ASTEC development by IRSN and GRS the code was widely applied to VVER reactors. In this paper, at first specific features of VVER-440/V213 reactor design that are important from the modelling point of view are briefly described. Then the validation of ASTEC code with focus on its applicability to VVER reactors is briefly summarised and the results obtained with the ASTEC V2.0-rev1 version for the ISP-33 PACTEL natural circulation experiment are presented. In the next section the application of ASTEC V2.0-rev1 code in upgrade of VVER-440/V213 NPPs to cope with consequences of severe accidents is described. This upgrade includes adoption of in-vessel retention via external reactor vessel cooling and installation of large capacity passive autocatalytic recombiners. Results of analysis with focus on corium localisation and stabilisation inside reactor vessel, hydrogen control in confinement and prevention of long-term confinement pressurisation are presented.

    2009-01-01

    The report presents the results from severe accident analyses performed with the both versions of ASTEC v1.3 and ASTEC v1.3R2 computer code for a VVER 1000 type of reactor. The purpose of this analysis is to assess the progress of ASTEC code modeling of main phenomena arising during hypothetical severe accidents. The final target of these analyses is to estimate the behaviour of the ASTEC code, its capability for simulation of severe accidents, including safety systems and Severe Accident Management (SAM) procedures. The analyses have been performed assuming a station blackout with simultaneous loss of HPIS, LPIS (ECCSs), EFWS and spray system due to failure of DGs. Hydro accumulators are not available. In the calculation it is assumed opening and stuck-open of PRZ relief valves. It has been organized the Fission Products path through the SEMPELL valve. It should be said that this investigation was limited to the 'in-vessel' phase of the sequence; therefore the effect of sprays on containment atmosphere has not been studied. (authors)

    The ASTEC code (jointly developed by IRSN and GRS, i.e. Gesellschaft fur Anlagen- und Reaktorsicherheit mbH) development is aimed to provide an integral code for the simulation of the whole course of severe accidents in Light-Water Reactors. ASTEC is a complex system of codes for reactor safety assessment. In this benchmark, only the CPA (Containment Part of ASTEC) module is used. CPA is a lumped-parameter able to represent a multi-compartments containment. It used the following main elements: zones (compartments), junctions (liquids and atmospherics) and structures. The zones are connected by junctions and contain steam, water and non condensable gases. They exchange heat with structures by different heat transfer regimes: convection, radiation and condensation. In this paper, three selected from the PANDA SETH Benchmark 9, 9bis and 25 are considered to investigate the impact of injection velocity and steam condensation on the plume shape and on gas distribution. Coarse and fine meshes were developed by considering the test facility with the two vessels DW1, DW2, and the interconnection pipe. The obtained numerical results are analyzed and compared to the experiments. The comparison shows the good agreement between experiments and calculations. (author)

    This paper deals with an assessment of ASTEC1.1v0 code in the simulation of small and medium break LOCAs (ranging from 30mm up to 70mm equivalent diameter). The reference power plant for this analysis is a VVER-1000/V320 (e.g. Units 5 and 6 at Kozloduy NPP). A preliminary comparison with MELCOR and RELAP-SCDAP severe accident codes will be discussed. This investigation has been performed in the framework of the SARNET project (under the Euratom 6 th framework program) by the FoBAUs group (Forum of Bulgarian ASTEC users). The FoBAUs group aims at the validation of the ASTEC code in the field of severe accidents. Future activities will target the ASTEC capability (as a PSA-level 2 tool) to simulate a large range of reactor accident scenarios with intervention of safety systems (either passive systems or operated by operators). The final target is to assess Severe Accident Management (SAM) procedures for VVER-1000 reactors. The ASTEC1.1v0 code version here used is the one released in June 2004 by the French IRSN (Institut de Radioprotection et de Surete Nucleaire) and the German GRS (Gesellschaft ReactorSicherheit mbH).

    The ASTEC (Analysis and Simulation Tools for Engineering Controls) software is under development at the Goddard Space Flight Center (GSFC). The design goal is to provide a wide selection of controls analysis tools at the personal computer level, as well as the capability to upload compute-intensive jobs to a mainframe or supercomputer. In the last three years the ASTEC (Analysis and Simulation Tools for Engineering Controls) software has been under development. ASTEC is meant to be an integrated collection of controls analysis tools for use at the desktop level. MODEL (Multi-Optimal Differential Equation Language) is a translator that converts programs written in the MODEL language to FORTRAN. An upgraded version of the MODEL program will be merged into ASTEC. MODEL has not been modified since 1981 and has not kept with changes in computers or user interface techniques. This paper describes the changes made to MODEL in order to make it useful in the 90's and how it relates to ASTEC.

    2014-01-01

    Ruhr-Universitaet Bochum performed in a German funded project validation of in-vessel and containment models of the integral code ASTEC V2, jointly developed by IRSN (France) and GRS (Germany). In this paper selected results of this validation are presented. In the in-vessel part, the main point of interest was the validation of the code capability concerning cladding oxidation and hydrogen generation. The ASTEC calculations of QUENCH experiments QUENCH-03 and QUENCH-11 show satisfactory results, despite of some necessary adjustments in the input deck. Furthermore, the oxidation models based on the Cathcart–Pawel and Urbanic–Heidrick correlations are not suitable for higher temperatures while the ASTEC model BEST-FIT based on the Prater–Courtright approach at high temperature gives reliable enough results. One part of the containment model validation was the assessment of three hydrogen combustion models of ASTEC against the experiment BMC Ix9. The simulation results of these models differ from each other and therefore the quality of the simulations depends on the characteristic of each model. Accordingly, the CPA FRONT model, corresponding to the simplest necessary input parameters, provides the best agreement to the experimental data

    Highlights: • Recent modelling improvements of the ASTEC European severe accident code are outlined. • Key new physical models now available in the ASTEC V2.1 major version are described. • ASTEC progress towards a multi-design reactor code is illustrated for BWR and PHWR. • ASTEC strong link with the on-going EC CESAM FP7 project is emphasized. • Main remaining modelling issues (on which IRSN efforts are now directing) are given. - Abstract: A new major version of the European severe accident integral code ASTEC, developed by IRSN with some GRS support, was delivered in November 2015 to the ASTEC worldwide community. Main modelling features of this V2.1 version are summarised in this paper. In particular, the in-vessel coupling technique between the reactor coolant system thermal-hydraulics module and the core degradation module has been strongly re-engineered to remove some well-known weaknesses of the former V2.0 series. The V2.1 version also includes new core degradation models specifically addressing BWR and PHWR reactor types, as well as several other physical modelling improvements, notably on reflooding of severely damaged cores, Zircaloy oxidation under air atmosphere, corium coolability during corium concrete interaction and source term evaluation. Moreover, this V2.1 version constitutes the back-bone of the CESAM FP7 project, which final objective is to further improve ASTEC for use in Severe Accident Management analysis of the Gen.II–III nuclear power plants presently under operation or foreseen in near future in Europe. As part of this European project, IRSN efforts to continuously improve both code numerical robustness and computing performances at plant scale as well as users’ tools are being intensified. Besides, ASTEC will continue capitalising the whole knowledge on severe accidents phenomenology by progressively keeping physical models at the state of the art through a regular feed-back from the interpretation of the current and

    2014-01-01

    One main goal of the severe accident integral code ASTEC V2, jointly developed since almost more than 15 years by IRSN and GRS, is to simulate the overall behaviour of fission products (FP) in a damaged nuclear facility. ASTEC applications are source term determinations, level 2 Probabilistic Safety Assessment (PSA2) studies including the determination of uncertainties, accident management studies and physical analyses of FP experiments to improve the understanding of the phenomenology. ASTEC is a modular code and models of a part of the phenomenology are implemented in each module: the release of FPs and structural materials from degraded fuel in the ELSA module; the transport through the reactor coolant system approximated as a sequence of control volumes in the SOPHAEROS module; and the radiochemistry inside the containment nuclear building in the IODE module. Three other modules, CPA, ISODOP and DOSE, allow respectively computing the deposition rate of aerosols inside the containment, the activities of the isotopes as a function of time, and the gaseous dose rate which is needed to model radiochemistry in the gaseous phase. In ELSA, release models are semi-mechanistic and have been validated for a wide range of experimental data, and noticeably for VERCORS experiments. For SOPHAEROS, the models can be divided into two parts: vapour phase phenomena and aerosol phase phenomena. For IODE, iodine and ruthenium chemistry are modelled based on a semi-mechanistic approach, these FPs can form some volatile species and are particularly important in terms of potential radiological consequences. The models in these 3 modules are based on a wide experimental database, resulting for a large part from international programmes, and they are considered at the state of the art of the R and D knowledge. This paper illustrates some FPs modelling capabilities of ASTEC and computed values are compared to some experimental results, which are parts of the validation matrix

    In recent European Union commissioned report, there was no evidence that the air raid of the NATO military in Yugoslavia became a cause of the large-scale ecology destruction until now. However, the pollution is very serious in industrial area suburb which becomes a target for Novi Sad and Pacncevo, Prahovo. The Hungary-based Regional Environment Center for Central and Eastern Europe in Hungary: REC was reported. According to REC, the pollution of the Danube river after the air raid which reaches for 11 weeks by the NATO military was serious, and ammonia of 100 tons, ethylene dichloride over the 1 thousand tons, 33% hydrochloric acid solution of the 1 thousand tons escaped to the Danube river from the air raid of Pancevo on April 18th. And, the mercury accumulated in sodium hydroxide of about 3 thousand tons, liquid chlorine of several decade tons and chlorine/alkali plant also escaped from Pancevo. United Nations-led Environmental Damage Assessment Mission should inspect Kosovo and Yugoslavia on July 19th, and it was announced with 'NATO does not show still us all well-informed information'. The investigation is carried out on the item which the Yugoslavia authorities designates, and the atmosphere level of VCM has reached 10600 times the concentration of the acceptable level near Pancevo, and it reports that acid rain was observed in each place.

    ASTEC, jointly developed by IRSN and GRS, is considered as the European reference code since it capitalizes knowledge from the European research on the domain. The CESAM project aims at its enhancement and extension for use in severe accident management (SAM) analysis of the nuclear power plants (NPP) of Generation II-III presently under operation or foreseen in near future in Europe, spent fuel pools included. Within the CESAM project 3 main types of research activities are performed: -) further validation of ASTEC models important for SAM, in particular for the phenomena being of importance in the Fukushima-Daichi accidents, such as reflooding of degraded cores, pool scrubbing, hydrogen combustion, or spent fuel pools behaviour; -) modelling improvements, especially for BWR or based on the feedback of validation tasks; and -) ASTEC applications to severe accident scenarios in European NPPs in order to assess prevention and mitigation measures. An important step will be reached with the next major ASTEC V2.1 version planned to be delivered in the first part of 2015. Its main improvements will concern the possibility to simulate in details the core degradation of BWR and PHWR and a model of reflooding of severely degraded cores. A new user-friendly Graphic User Interface will be available for plant analyses

    In this paper a comparison between severe accident calculations performed for a WWER 1000 with the ASTEC1.1v0 and MELCOR 1.8.5 computer codes for a small break LOCA (ID 60 mm) without intervention of hydro accumulators is presented. This investigation has been performed in the framework of the SARNET project under the EURATOM 6th framework program. Once the accident sequence scenario is specified, both codes (MELCORE and ASTEC) are able to determine the core and containment damaged states, to estimate the release of radionuclides from the fuel as well as from the primary circuit and containment. Theses results are used to estimate the maximum period of the time during which the personnel could still take particular decisions in order to mitigate such an accident. The aim of the performed analysis is to estimate the discrepancy between ASTEC and MELCORE 1.8.5 calculations. Such discrepancies will be studied, if the case, proposal for ASTEC improvements will be made. Also the ASTEC capability to simulate specific reactor accident scenarios and/or particular safety systems will be tested. The final target is to propose severe accident management procedure for WWER 1000 reactors. In conclusions, the analysis for a small break LOCA (ID 60 mm without hydroelectricities) has shown some discrepancies between ASTEC and MELCORE especially during the degradation of the core. Further analyses are planed in which the MELCORE temperature 'set point' for core degradation (2520 K) will be progressively increased to approach the ASTEC one (which has been estimated to be about 3200 K). The comparison of the new results will allow a better evaluation of the in-vessel models implemented in ASTEC

    The French Institut de Radioprotection et de Surete Nucleaire (IRSN) is performing a level 2 Probabilistic Safety Assessment (PSA-2) on the French 1300 MWe reactors. This PSA-2 is heavily relying on the ASTEC integral computer code, jointly developed by IRSN and GRS (Germany). In order to assess the reliability and the quality of physical results of the ASTEC V1.3 code as well as the PWR 1300 MWe reference input deck, an important series of benchmarks with the French best-estimate thermal-hydraulic code CATHARE 2 V2.5 has been performed on 14 different severe accident scenarios. The present paper details 2 out of the 14 studied scenarios: a 12 inches cold leg Loss of Coolant Accident (LOCA) and a 2 tubes Steam Generator Tube Rupture (SGTR). The thermal-hydraulic behavior of the primary and secondary circuits is thoroughly investigated and the ASTEC results of the core degradation phase are presented. Overall, the thermal-hydraulic behavior given by the ASTEC V1.3 is in very good agreement with the CATHARE 2 V2.5 results. (author)

    An important element for the fielding of a viable, effective NATO Response Force (NRF) is access to meteorological, oceanographic, geospatial data (GEOMETOC) and imagery. Currently, the available GEOMETOC information suffers from being very fragmented. NATO defines the Recognised Environmental Picture as controlled information base for GEOMETOC data. The NATO REP proposes an architecture that is both flexible and open. The focus lies on enabling a network-centric approach. The key into achieving this is relying on using open, well recognized standards that apply to both the data exchange protocols and the data formats. Communication and information exchange based on open standards enables system interoperability. Diverse systems, each with unique, specialized contributions to an increased understanding of the battlespace, can now cooperate to a manageable information sphere. By clearly defining responsibilities in the generation of information, a reduction in data transfer overhead is achieved . REP identifies three main stages in the dissemination of GEOMETOC data. These are Collection, Fusion (and Analysis) and Publication. A REP architecture has been successfully deployed during the NATO Coalition Warrior Interoperability Demonstration (CWID) in Lillehammer, Norway during June 2005. CWID is an annual event to validate and improve the interoperability of NATO and national Consultation and command, control, communications, computers, intelligence, surveillance, and reconnaissance (C4ISR) systems. With a test case success rate of 84%, it was able to provide relevant GEOMETOC support to the main NRF component headquarters. In 2006, the REP architecture will be deployed and validated during the NATO NRF Steadfast live exercises.

  1. ICARE/CATHARE and ASTEC code development trends

    International Nuclear Information System (INIS)

    Chatelard, P.; Dorsselaere, J.-P. van

    2000-01-01

    Regarding the computer code development for simulation of LWR severe accidents, IPSN developed a two-tier approach based on detailed codes such as ICARE/CATHARE and simplified models to be assembled in the ASTEC integral code. The ICARE/CATHARE code results from the coupling between the ICARE2 code modelling the core degradation phenomena and the thermalhydraulics code CATHARE2. It allows to calculate PWR and VVER severe accident sequences in the whole RCS. The modelling of the early degradation phase can be considered as rather complete in the ICARE/CATHARE V1 mod1 version (to be released by mid-2000) whereas some models are still missing for the late phase. The main future developments (ICARE/CATHARE V2) will concern the multi-dimensional thermalhydraulics, the quenching of partially damaged cores (mechanical and chemical effects), the debris bed two-phase thermalhydraulics (including reflooding) and the corium behaviour in the lower head. The main other physical improvements should concern the behaviour of boron carbide control rods, the processes governing the core loss of geometry (transition phase) and the oxidation of relocated melts. The ASTEC (Accident Source Term Evaluation Code) integral code, commonly developed by IPSN and GRS, aims to predict an entire LWR (PWR, VVER and BWR) severe accident sequence from the initiating event through to FP release out of the containment, for source term, PSA level 2, or accident management studies. The version ASTEC VO.3 to be released by mid-2000 can be considered now as robust and fast-running enough (between 2 and 12 hours for a one day accident) and allows to perform, with a containment multi-compartment configuration, any scenario accident study accounting for the main safety systems and operator procedures (spray, recombiner, etc.). The next version ASTEC V1, to be released beginning of 2002, will include the frontend simulation and improve modelling of in-vessel core degradation. A large validation activity will

    Van Dorsselaere, J.P.; Jacq, F.; Allelein, H.J.

    2000-01-01

    The ASTEC (Accident Source Term Evaluation Code) integrated code is developed since 1997 in close collaboration by IPSN and GRS to predict an entire LWR severe accident sequence from the initiating event up to Fission Product (FP) release out of the containment. The applications of such a code are source term determination studies, scenario evaluations, accident management studies and Probabilistic Safety Assessment level 2 (PSA-2) studies. The version V0 of ASTEC is based on the RCS modules of the ESCADRE integrated code (IPSN) and on the upgraded RALOC and FIPLOC codes (GRS) for containment thermalhydraulics and aerosol behaviour. The latest version V0.2 includes the general feed-back from the overall validation performed in 1998 (25 separate-effect experiments, PHEBUS.FP FPT1 integrated experiment), some modelling improvements (i.e. silver-iodine reactions in the containment sump), and the implementation of the main safety systems for Severe Accident Management. Several reactor-applications are under way on French and German PWR, and on VVER-1000, all with a multi-compartment configuration of the containment. The total IPSN-GRS manpower involved in ASTEC project is today about 20 men/year. The main evolution of the next version V1, foreseen end of 2001, concerns the integration of the front-end phase and the improvement of the in-vessel degradation late-phase modelling. (author)

    The severe accident integral code ASTEC, jointly developed since almost 20 years by IRSN and GRS, simulates the behaviour of a whole nuclear power plant under severe accident conditions, including severe accident management by engineering systems and procedures. Since 2004, the ASTEC code is progressively becoming the reference European severe accident integral code through in particular the intensification of research activities carried out in the frame of the SARNET European network of excellence. The first version of the new series ASTEC V2 was released in 2009 to about 30 organizations worldwide and in particular to SARNET partners. With respect to the previous V1 series, this new V2 series includes advanced core degradation models (issued from the ICARE2 IRSN mechanistic code) and necessary extensions to be applicable to Gen. III reactor designs, notably a description of the core catcher component to simulate severe accidents transients applied to the EPR reactor. Besides these two key-evolutions, most of the other physical modules have also been improved and ASTEC V2 is now coupled to the SUNSET statistical tool to make easier the uncertainty and sensitivity analyses. The ASTEC models are today at the state of the art (in particular fission product models with respect to source term evaluation), except for quenching of a severely damage core. Beyond the need to develop an adequate model for the reflooding of a degraded core, the main other mean-term objectives are to further progress on the on-going extension of the scope of application to BWR and CANDU reactors, to spent fuel pool accidents as well as to accidents in both the ITER Fusion facility and Gen. IV reactors (in priority on sodium-cooled fast reactors) while making ASTEC evolving towards a severe accident simulator constitutes the main long-term objective. This paper presents the status of the ASTEC V2 versions, focussing on the description of V2.0 models for water-cooled nuclear plants

  6. Continuous validation of ASTEC containment models and regression testing

    Nowack, Holger; Reinke, Nils; Sonnenkalb, Martin

    2014-01-01

    The focus of the ASTEC (Accident Source Term Evaluation Code) development at GRS is primarily on the containment module CPA (Containment Part of ASTEC), whose modelling is to a large extent based on the GRS containment code COCOSYS (COntainment COde SYStem). Validation is usually understood as the approval of the modelling capabilities by calculations of appropriate experiments done by external users different from the code developers. During the development process of ASTEC CPA, bugs and unintended side effects may occur, which leads to changes in the results of the initially conducted validation. Due to the involvement of a considerable number of developers in the coding of ASTEC modules, validation of the code alone, even if executed repeatedly, is not sufficient. Therefore, a regression testing procedure has been implemented in order to ensure that the initially obtained validation results are still valid with succeeding code versions. Within the regression testing procedure, calculations of experiments and plant sequences are performed with the same input deck but applying two different code versions. For every test-case the up-to-date code version is compared to the preceding one on the basis of physical parameters deemed to be characteristic for the test-case under consideration. In the case of post-calculations of experiments also a comparison to experimental data is carried out. Three validation cases from the regression testing procedure are presented within this paper. The very good post-calculation of the HDR E11.1 experiment shows the high quality modelling of thermal-hydraulics in ASTEC CPA. Aerosol behaviour is validated on the BMC VANAM M3 experiment, and the results show also a very good agreement with experimental data. Finally, iodine behaviour is checked in the validation test-case of the THAI IOD-11 experiment. Within this test-case, the comparison of the ASTEC versions V2.0r1 and V2.0r2 shows how an error was detected by the regression testing

    Highlights: • ASTEC-Na results for CABRI BI1 test have been compared with experimental data. • The ASTEC-Na calculations reached the boiling onset within the error bar of the test. • The coolant axial profile in ASTEC-Na fit almost perfectly with the experimental data. • All the calculations have a good agreement with the two-phase front downwards. • All the calculations have a worse agreement with the two-phase front upwards. - Abstract: This paper presents simulation results of the CABRI BI1 test using the code ASTEC-Na, currently under development, as well as a comparison of the results with available experimental data. The EU-JASMIN project (7th FP of EURATOM) centres on the development and validation of the new severe accident analysis code ASTEC-Na (Accident Source Term Evaluation Code) for sodium-cooled fast reactors whose owner and developer is IRSN. A series of experiments performed in the past (CABRI/SCARABEE experiments) and new experiments to be conducted in the new experimental sodium facility KASOLA have been chosen to validate the developed ASTEC-Na code. One of the in-pile experiments considered for the validation of ASTEC-Na thermal–hydraulic models is the CABRI BI1 test, a pure loss-of-flow transient using a low burnup MOX fuel pin. The experiment resulted in a channel voiding as a result of the flow coast-down leading to clad melting. Only some fuel melting took place. Results from the analysis of this test using SIMMER and SAS-SFR codes are also presented in this work to check their suitability for further code benchmarking purposes.

The NDPP directly affects national defence plans by harmonizing them with identified security and defence objectives as well by influencing development of the novel national defence capabilities. The emergence of new threats in the NATO environment, demands modifications in the defense planning process and establishing new goals for the Alliance. Enhancement of the NDPP should be priority during the time of unrest.

  10. Fission product release from nuclear fuel I. Physical modelling in the ASTEC code

    Highlights: • Physical modeling of FP and SM release in ASTEC is presented. • The release is described as solid state diffusion within fuel for high volatile FP. • The release is described as FP vaporisation for semi volatile FP. • The release is described as fuel vaporisation for low volatile FP. • ASTEC validation is presented in the second paper. - Abstract: This article is the first of a series of two articles dedicated to the mechanisms of fission product release from a degraded core as they are modelled in the ASTEC code. The ASTEC code aims at simulating severe accidents in nuclear reactors from the initiating event up to the radiological consequences on the environment. This code is used for several applications such as nuclear plant safety evaluation including probabilistic studies and emergency preparedness. To cope with the requirements of robustness and low calculation time, the code is based on a semi-empirical approach and only the main limiting phenomena that govern the release from intact rods and from debris beds are considered. For solid fuel, fission products are classified into three groups, depending on their degree of volatility. The kinetics of volatile fission products release depend on the rate-limiting process of solid-state diffusion through fuel grains. For semi-volatile fission products, the release from the open fuel porosities is assumed to be governed by vaporisation and mass transfer processes. The key phenomenon for the release of low volatile fission products is supposed to be fuel volatilisation. A similar approach is used for the release of fission products from a rubble bed. An in-depth validation of the code including both analytical and integral experiments is the subject of the second article

    In connection with the provision of tools for the assessment of incident and accident sequences and of accident management measures in nuclear power plants, the Federal Ministry of Economics and Technology (BMWi) sponsored in this project a further validation of the COCOSYS (Containment Code System) code system and the Franco- German ASTEC (Accident Source Term Evaluation Code) integral code. COCOSYS is being developed and validated for the comprehensive simulation of severe accidents in a light-water reactor (LWR) containment as well as analytical monitoring of experiments. The general objective is the simulation of all relevant processes and conditions in the containment during the process of a severe accident (including design basis accidents). This is to include also the consideration of all relevant interactions between the various phenomena. ASTEC is being jointly developed by IRSN and GRS with the aim to provide a fast running code for the calculation of the entire sequence of a severe accident in a light-water reactor, starting from the initiating event including the release of fission products into the environment. The code's fields of application are level-2 probabilistic safety analyses, the analysis of incident and accident sequences, uncertainty and sensitivity analyses as well as the analytical evaluation of experiments. The performed work within the COCOSYS project involves the validation of the new iodine module AIM-3 as well as the corresponding monitoring of iodine experiments inside the THAI facility. Main focus of these experiments was the interaction of iodine with steel and paint, radiolytic interactions and iodine ozone reaction. The extensions of fire simulations with COCOSYS regarding plume simulation and soot transport have been examined successfully on the basis of further experiments within the OECD PRISME project. A further main focus is the combined use and comparison of calculated results of COCOSYS, a lumped parameter code, and

  14. On boundary layer modelling using the ASTEC code

    International Nuclear Information System (INIS)

    Smith, B.L.

    1991-07-01

    The modelling of fluid boundary layers adjacent to non-slip, heated surface using the ASTEC code is described. The pricipal boundary layer characteristics are derived using simple dimensional arguments and these are developed into criteria for optimum placement of the computational mesh to achieve realistic simulation. In particular, the need for externally-imposed drag and heat transfer correlations as a function of the local mesh concentration is discussed in the context of both laminar and turbulent flow conditions. Special emphasis is placed in the latter case on the (k-ε) turbulence model, which is standard in the code. As far as possible, the analyses are pursued from first principles, so that no comprehensive knowledge of the history of the subject is required for the general ASTEC user to derive practical advice from the document. Some attention is paid to the use of heat transfer correlations for internal solid/fluid surfaces, whose treatment is not straightforward in ASTEC. It is shown that three formulations are possible to effect the heat transfer, called Explicit, Jacobian and Implicit. The particular advantages and disadvantages of each are discussed with regard to numerical stability and computational efficiency. (author) 18 figs., 1 tab., 39 refs

    1994-01-01

    As the role of the modern engineer is markedly different from that of even a decade ago, the theme of engineering mathematics educa­ tion (EME) is an important one. The need for mathematical model­ ling (MM) courses and consideration of the educational impact of computer-based technology environments merit special attention. This book contains the proceeding of the NATO Advanced Research Workshop held on this theme in July 1993. We have left the industrial age behind and have entered the in­ formation age. Computers and other emerging technologies are penetrating society in depth and gaining a strong influence in de­ termining how in future society will be organised, while the rapid change of information requires a more qualified work force. This work force is vital to high technology and economic competitive­ ness in many industrialised countries throughout the world. Within this framework, the quality of EME has become an issue. It is expected that the content of mathematics courses taught in schools o...

  1. Progress and perspectives of ASTEC applications in the European Network SARNET

    International Nuclear Information System (INIS)

    Van Dorsselaere, J.P.; Allelein, H.J.; Neu, K.

    2006-01-01

    The ASTEC integral code is jointly developed by IRSN (France) and GRS (Germany) for LWR source term Severe Accident (SA) evaluation, PSA level 2 studies and SA management evaluation. ASTEC constitutes now the reference European integral code through its role in the Network SARNET (Severe Accident Network of Excellence) in the EC 6. Framework Program. The models of next version V1.3, released before end of 2006, represent the current State of the Art, its validation is very extensive (in particular on Phebus FP) and, after next implementation of a model for reflooding of degraded cores, it will cover all needs for SA evaluation in PWR and VVER. It will be the reference code for the IRSN PSA level 2 (Probabilistic Safety Analysis) on French PWR 1300 MWe that starts in 2006. In the frame of SARNET, IRSN coordinates the ASTEC Topic gathering 30 partners that assess the code through validation against experiments and benchmarks with reference codes like CATHARE or RELAP5 for the reactor coolant circuit and COCOSYS for the containment. Plant application calculations are compared with MELCOR and MAAP4 results for a series of different SA sequences. Besides, the knowledge generated by SARNET Topics (Corium, Source Term and Containment) will be progressively integrated into the code through improved or new models. The 2. Users' Club organized at Aix-en-Provence in June 06, with 45 participants from 27 organizations, allowed fruitful discussions with the Maintenance Team. After 2 years of work, code validation shows good overall results, often close to results of reference codes. Some results reach the limits of present knowledge, for instance on Molten-Corium-Concrete-Interaction (MCCI) and Direct Containment Heating (DCH). Benchmarks on plant applications have been performed on diverse reactor types: PWR 900, Konvoi 1300, Westinghouse 1000, VVER-1000 and VVER-440. The main trends of results are similar to MELCOR or MAAP4 results. The objective of the quantitative

    The ASTEC-Na code was further developed and assessed in the frame of JASMIN project of the 7th EU Framework Program to extend the original capability of ASTEC, dealing with severe accident analysis in LWR to Sodium-cooled Fast Reactors (SFR). The in-pile BE+3 experiment from the SCARABEE-N program has been simulated with ASTEC-Na for thermal-hydraulic models validation purpose. The adequacy of ASTEC-Na thermal-hydraulic models has been also investigated through the comparison with other safety analysis codes. The analysis of SCARABEE BE+3 test confirms the good performance of ASTEC-Na code in the calculation of single-phase conditions and boiling onset, while larger deviations are encountered in the analysis of the two-phase conditions, mainly regarding the propagation of the boiling front. Furthermore, reasonable agreement was found with other code results. (author)

    In the frame of PHEBEN2 project (Validation of the severe accidents codes for applications to nuclear power plants, based on the PHEBUS FP experiments), a project developed within the EU research Frame Program 5 (FP5), the INR-Pitesti's team has received the task of determining the ASTEC code sensitivity. The PHEBEN2 project has been initiated in 1998 and gathered 13 partners from 6 EU member states. To the project 4 partners from 3 candidate states (Hungary, Bulgaria and Romania) joined later. The works were contracted with the European Commission (under FIKS-CT1999-00009 contract) that supports financially the research effort up to about 50%. According to the contract provisions, INR's team participated in developing the Working Package 1 (WP1) which refers to validation of the integral computation codes that use the PHOEBUS experimental data and the Working Package 3 (WP3) referring to the evaluation of the codes to be applied in nuclear power plants for risk evaluation, nuclear safety margin evaluation and determination/evaluation of the measures to be adopted in case of severe accident. The present work continues the efforts to validate preliminarily the ASTEC code. Focused are the the stand-alone sensitivity analyses applied to two most important modules of the code, namely DIVA and SOPHAEROS

  4. Validation of Code ASTEC with LIVE-L1 Experimental Results

    2008-01-01

    The severe accidents with core melting are considered at the design stage of project at Generation 3+ of Nuclear Power Plants (NPP). Moreover, there is an effort to apply the severe accident management to the operated NPP. The one of main goals of severe accidents mitigation is corium localization and stabilization. The two strategies that fulfil this requirement are: the in-vessel retention (e.g. AP-600, AP- 1000) and the ex-vessel retention (e.g. EPR). To study the scenario of in-vessel retention, a large experimental program and the integrated codes have been developed. The LIVE-L1 experimental facility studied the formation of melt pools and the melt accumulation in the lower head using different cooling conditions. Nowadays, a new European computer code ASTEC is being developed jointly in France and Germany. One of the important steps in ASTEC development in the area of in-vessel retention of corium is its validation with LIVE-L1 experimental results. Details of the experiment are reported. Results of the ASTEC (module DIVA) application to the analysis of the test are presented. (author)

    This paper presents the results of a comparative analysis performed with ASTEC V2.02 and a coupled ATHLET-CD V2.2c /COCOSYS V2.4 calculation for a German 1300 MWe KONVOI type PWR. The purpose of this analysis is mainly to assess the ASTEC code behaviour in modelling of both the thermal-hydraulic phenomena in the coolant circuit arising during a hypothetical severe accident and the early phase of the core degradation versus the more mechanistic code system ATHLET-CD/COCOSYS. The performed analyses cover a loss of coolant accident sequence (LOCA). Such comparison has been done for the first time. The integral code ASTEC (Accident Source Term Evaluation Code) commonly developed since 1996 by IRSN and GRS is a fast running programme, which allows the calculation of entire sequences of severe accidents (SA) in light water reactors from the initiating event up to the release of fission products into the environment, thereby covering all important in-vessel and containment phenomena. The thermal-hydraulic mechanistic system code ATHLET (Analysis of THermal-hydraulics of LEaks and Transients) is being developed by GRS for the analysis of the whole spectrum of leaks and transients in PWRs and BWRs. For modeling of core degradation processes the CD part (Core Degradation) of ATHLET can be activated. For analyses of the containment behavior, ATHLET-CD has been coupled to the GRS code COCOSYS (COntainment COde SYStem). (orig.)

    The main purpose of this study is to calculate the COLIMA CA-U3 experimental test with the ELSA module of the ASTEC code. This experimental test was performed to represent the fission product and structural material releases from a VVER-440 magma type configuration. Thus, some additional work is also done on test result analyses and corresponding ASTEC parameter usage to model as closely as possible the test configuration. Code results on fission product releases are compared to experimental results in a qualitative way for all elements that can be evaluated by the ASTEC code. Sensitivity cases are also performed on the gas flow rate carrying the fission product. (author)

    2011-01-01

    During a hypothetic severe accident in the NPP involving degradation of the core of a light water reactor, hydrogen could be generated and released into the containment atmosphere posing a deflagration or even a detonation risk. In the case of deflagration, the integrity of the containment would be threatened by the increase of the containment atmosphere pressure and temperature. Other risks of containment damage due to turbulent flames exist, caused by high pressure pulses, shock waves and etc. For the simulation of such processes a reliable numerical codes are needed. Despite flame acceleration being largely studied for homogeneous hydrogen - air mixtures, there are still unresolved issues in this research area, e.g., the effect of turbulence level on flame acceleration and quenching. This paper presents simulations of hydrogen deflagration experiments in the ENACCEF facility using ASTEC code, performed in the frames of International Standard Program No. 49 and SARNET2 project. Experiments and simulations were performed with the aim of evaluating the codes' (a number of participants with various codes participated in the project) capabilities to simulate hydrogen combustion. ASTEC code is an integral lumped-parameter approach based nuclear safety analysis code. For the presented simulations, ASTEC modules CPA (containment thermohydromechanics) and FRONT (hydrogen deflagration) were used. Paper present ENACCEF test facility, its nodalisation schemes developed for the calculations, simulated experiments and simulations' results. Brief description of FRONT module is also presented. Calculations' results are compared with experimental results and analyzed. (author)

    2013-01-01

    Highlights: • A wide range of experiments is presented for the ASTEC/ELSA code validation. • Analytical tests such as AECL, ORNL and VERCORS are considered. • A large-scale experiment, PHEBUS FPT1, is considered. • The good agreement with measurements shows the efficiency of the ASTEC modelling. • Improvements concern the FP release modelling from MOX and high burn-up UO 2 fuels. - Abstract: This article is the second of two articles dedicated to the mechanisms of fission product release from a degraded core. The models of fission product release from nuclear fuel in the ASTEC code have been described in detail in the first part of this work (Brillant et al., this issue). In this contribution, the validation of ELSA, the module of ASTEC that deals with fission product and structural material release from a degraded core, is presented. A large range of experimental tests, with various temperature and conditions for the fuel surrounding atmosphere (oxidising and reducing), is thus simulated with the ASTEC code. The validation database includes several analytical experiments with both bare fuel (e.g. MCE1 experiments) and cladded fuel (e.g. HCE3, VERCORS). Furthermore, the PHEBUS large-scale experiments are used for the validation of ASTEC. The rather satisfactory comparison between ELSA calculations and experimental measurements demonstrates the efficiency of the analytical models to describe fission product release in severe accident conditions

    Due to their specific properties, polymers with well-defined structures have been receiving increasing attention over the last several years. Owing to the wide variability of their properties, these specialty polymers have been used in various areas from biomedical engineering to electronics or energy applications. The synthesis of such polymers necessi­ tates the use of new methods of polymerization which derived from an insight into the mechanism of polymerization reactions. A NATO Advanced Research Workshop on "Frontiers in Polymerization Catalysis and Polymer Synthesis" was held in BANDOl (FRANCE) in February 1987. Its aim was to assess the new polymerization methods, as well as the latest advances in the mechanisms of conventional polymerization reactions together with their applications to the synthesis of new macromolecular structures.

    1978-01-01

    This book contains the proceedings of the first international symposium devoted to research on the evaluation and planning of new person-to-person telecommunication systems. It was sponsored by NATO's Special Programme Panel on Systems Science and took place, in September 1977, at the University of Bergamo in the north of Italy. Telecommunication systems which provide for communication be­ tween people, rather than computers or other instruments, are of two kinds. There are mass communication systems (broadcast radio and television) and interpersonal systems (for example, the telephone and Telex) which join together individuals or small groups.

    51 organizations from Europe and Canada cooperated within SARNET (Severe Accident Research Network of Excellence) joining their capacities of research in order to resolve the most important pending issues for enhancing, in regard to Severe Accidents (SA), the safety of existing and future Nuclear Power Plants (NPPs). SARNET defines common research programmes and develops common computer codes and methodologies for safety assessment. The ASTEC integral code, jointly developed by IRSN (France) and GRS (Germany) for Light Water Reactor (LWR) source term SA evaluation, Probabilistic Safety Assessment (PSA) level-2 studies and SA management evaluation, is the main integrating component of SARNET. The scientific knowledge generated in the Corium, Source Term and Containment Topics has been integrated into the code through improved or new physical models. ASTEC constitutes now the reference European SA integral code. During the 4 and half years of SARNET, 30 partners have assessed the successive versions of the ASTEC V1 code through validation. More than 60 scientists have been trained on the code use. Validation tasks on about 65 experiments were performed to cover all physical phenomena occurring in a severe accident: circuit thermalhydraulic, core degradation, fission products (FP) release and transport, Molten-Corium-Concrete-Interaction (MCCI), and in the containment, thermalhydraulic, aerosol and iodine as well as hydrogen behaviour. The overall status of validation can be considered as good, with results often close to results of mechanistic codes. Some reach the limits of present knowledge, for instance on MCCI, and, like in most codes, an adequate model for reflooding of a degraded core is still missing. IRSN and GRS are currently preparing the new series of ASTEC V2 versions that will account for most of the needs of evolution expressed by the SARNET partners. The first version V2.0, planned for March 09, will be applicable to EPR and will include the ICARE2

    The ASTEC code is progressively becoming the reference European severe accident integral code through in particular the intensification of research activities carried out since 2004. The purpose of this analysis is to assess ASTEC code modelling of main phenomena arising during hypothetical severe accidents and particularly in-vessel degradation in 2D geometry. The investigation covers both early and late phase of degradation of reactor core as well as determination of corium which will enter the reactor cavity. The initial event is station back-out. In order to receive severe accident condition, failure of all active component of emergency core cooling system is apply. The analysis is focus on ICARE module of ASTEC code and particularly on so call MAGMA model. The aim of study is to determine the capability of the integral code to simulate core degradation and to determine the corium composition entering the reactor cavity. (author)

    2015-06-01

    The present report is the 2 nd Technical Report of the research project ''Analysis and Evaluation of the ASTEC model basis'' funded by the Federal Ministry for Economic Affairs and Energy (BMWi 1501433) and conducted at the Reactor Simulation and Safety Group, Chair of Energy Systems and Energy Economics (LEE) at Ruhr-Universitaet Bochum. Within this report, the quality of a nuclear power plant simulation with ASTEC is investigated. Different parameters are varied to analyze the simulation stability within the dataset, which describes a generic German Konvoi power plant and is deposit in the program set of ASTEC. Firstly, plant specifications in the data set are checked for plausibility. In addition, the compliance of the data set with the nodalization rules is verified. After that, the stationary phase, in which no accident is calculated, is analyzed and parametric studies are performed in the transient phase, focusing on the primary and secondary circuit as well as on the containment behavior. The performed calculations focusing the primary and secondary circuit indicate a high dependency of the simulation results on the user's input in the data set. There are significant deviations between each simulations results, for example in the different calculated point of time of the reactor pressure vessel failure. Already changes in the stationary phase cause a significantly earlier reactor pressure vessel failure compared to the simulation with the original data. Beyond that, the location of the leakage of the reactor pressure vessel lower head varied and therefore cannot be clearly determined, although there have been no changes by the user on the accident course. A reliable indication of the plant behavior under severe accident conditions is therefore difficult using ASTEC. The results of the parametric studies within the Containment show the same significant influence of certain parameter changes on the simulation results. By using the

    This paper presents the modelling approach for LOCA 100 mm sequence for WWER 1000-B 320 type of reactor with the integral ASTEC computer code and SCDAP/RELAP5 computer code. As a basic input deck the reference input file for Balakovo NPP from the released ASTEC CD has been applied. As a first part of the calculations for the SBLOCA sequence the ASTEC v1.1 modules CESAR, DIVA and CPA have been activated in a coupled mode. For SCDAP/RELAP5 calculation input deck for WWER 1000-B 320 has been applied which meant to be closer to the initial boundary conditions applied for ASTEC WWER 1000 input deck. A SBLOCA 100 mm comparison between ASTEC v1.1 and SCADAP/RELAP5 has been presented. ASTEC predicts vessel failure at 15620 s. ASTEC and SCDAP/RELAP5 give close but not similar results - this could be observed on the trends. The comparison of 100 mm-break shows that SCDAP/RELAP5 predicts clear phenomenological changes in primary pressure evolution and molten pool formation. Similar hydrogen production mass for both codes around 5000 s is detected

    2015-01-01

    Highlights: • Model validation base extended to six FARO experiments. • Focus on the calculation of the fragmented particle diameter. • Capability and limits of the ASTEC fragmentation model. • Sensitivity analysis of model outputs. - Abstract: ASTEC is an integral code for the prediction of Severe Accidents in Nuclear Power Plants. As such, it needs to cover all physical processes that could occur during accident progression, yet keeping its models simple enough for the ensemble to stay manageable and produce results within an acceptable time. The present paper is concerned with the validation of the Corium jet fragmentation model of ASTEC v2.0 rev3 by means of a selection of six experiments carried out within the FARO facility. The different conditions applied within these six experiments help to analyse the model behaviour in different situations and to expose model limits. In addition to comparing model outputs with experimental measurements, sensitivity analyses are applied to investigate the model. Results of the paper are (i) validation runs, accompanied by an identification of situations where the implemented fragmentation model does not match the experiments well, and discussion of results; (ii) its special attention to the models calculating the diameter of fragmented particles, the identification of a fault in one model implemented, and the discussion of simplification and ad hoc modification to improve the model fit; and, (iii) an investigation of the sensitivity of predictions towards inputs and parameters. In this way, the paper offers a thorough investigation of the merit and limitation of the fragmentation model used in ASTEC

  8. Simulation of the fuel rod bundle test QUENCH-03 using the system codes ASTEC and ATHLET-CD

    2011-01-01

    The QUENCH-03 test was performed on the 21. of January 1999 at FZK (Forschungszentrum Karlsruhe) to investigate the behaviour on reflood of PWR (Pressurized Water Reactor) fuel rods with little oxidation. This paper presents the results of the simulation of QUENCH-03 performed with the version V1.3 of the integral code ASTEC (Accident Source Term Evaluation Code) which is being developed by IRSN (France) in cooperation with GRS (Germany) and with the program version 2.1A of the mechanistic code ATHLET-CD (Analysis of Thermal-hydraulics of Leaks and Transients - Core Degradation) which is under development by GRS. At first the QUENCH test facility and the QUENCH test program in general are described. The test conduct of the test QUENCH-03 follows as well as a description of the used codes ASTEC and ATHLET-CD with the associated modeling of the test section. The results of this calculation show that during the heat-up and transient phase both codes can calculate bundle and shroud temperatures as well as the hydrogen production in good approximation to the experimental data. During the quench phase and up to the end of the test only the oxidation model PRATER of ASTEC simulates the hydrogen production very well, the other oxidation models of ASTEC cannot calculate to some extent the measured amount of hydrogen. ATHLET-CD underestimates the integral amount at the end of the test. In the ASTEC calculations the temperatures during the quench phase show qualitatively good results, only time delays on some elevations of the bundle could be noticed. ATHLET-CD reproduces the thermal behaviour up to the first temperature escalation very well, after that the temperatures are partly over-estimated. The time delay recognized in the ASTEC calculations are seen as well. The results of the integral code ASTEC emphasize that the calculation of QUENCH-03 is possible and leading to good results concerning hydrogen release and corresponding temperatures. Because the QUENCH-03 test was

    This book covers latest development in theory and experiments of unconventional radiation production. Specifically, the generation of Tera-Hertz and X-ray radiation from low energy electron beams in the form of Channeling, Transition, Diffraction, Cherenkov, Smith-Purcell, PXR and Crystalline Undulator Radiation are presented. Material characteristics like thin targets, curved or bend crystals, inhomogeneous and left handed materials, multilayers as well as stimulation by external radiation are covered to demonstrate their influence in these processes. Novel ideas are offered on the use of such radiation in detectors and particle beam monitor development with improved energy or time resolution. The book assumes some familiarity of the reader with theoretical concepts underlying these phenomena and is therefore of primary use to the practicing scientist. More fundamental discussions of these phenomena can be found in the 2002 monograph "Electron-Photon Interaction in Dense Media" within the NATO Science Series...

  10. A fast running method for predicting the efficiency of core melt spreading for application in ASTEC

    International Nuclear Information System (INIS)

    Spengler, C.

    2010-01-01

    The integral Accident Source Term Evaluation Code (ASTEC) is jointly developed by the French Institut de Radioprotection et de Surete Nucleaire (IRSN) and the German Gesellschaft fuer Anlagen- und Reaktorsicherheit (GRS) mbH to simulate the complete scenario of a hypothetical severe accident in a nuclear light water reactor, from the initial event until the possible radiological release of fission products out of the containment. In the frame of the new series of ASTEC V2 versions appropriate model extensions to the European Pressurised Water Reactor (EPR) are under development. With view to assessing with ASTEC the proper operation of the ex-vessel melt retention and coolability concept of the EPR with regard to melt spreading an approximation of the area finally covered by the corium and of the distance run by the corium front before freezing is required. A necessary capability of ASTEC is in a first step to identify such boundary cases, for which there is a potential that the melt will freeze before the spreading area is completely filled. This paper presents a fast running method for estimating the final extent of the area covered with melt on which a simplified criterion in ASTEC for detecting such boundary cases will be based. If a boundary case is detected the application of a more-detailed method might be necessary to assess further the consequences for the accident sequence. The major objective here is to provide a reliable method for estimating the final result of the spreading and not to provide highly detailed methods to simulate the dynamics of the transient process.

    Molecular diffusion in rock matrix, called as matrix diffusion, has been appreciated as a static process for elemental migration in geological environment that has been acknowledged in the context of geological disposal of radioactive waste. However, incomprehensible enhancement of matrix diffusion has been reported at a number of field test sites. Here, the matrix diffusion of saline water at Horonobe, Hokkaido, Japan is highlighted directly probing angstrom-scale pores on a field scale up to 1 km by positron--positronium annihilation spectroscopy. The first application of positron--positronium annihilation spectroscopy to field-scale geophysical research reveals the slight variation of angstrom-scale pores influenced by saline water diffusion with complete accuracy. We found widely interconnected 3 Å pores, which offer the pathway of saline water diffusion with the highly enhanced effective matrix diffusion coefficient of 4× 10-6 cm2 s-1. The present findings provide unambiguous evidence that the angstrom-scale pores enhance effective matrix diffusion on a field scale in geological environment.

    The severe accident at the Fukushima-Daiichi nuclear power plant (NPP) has led to a worldwide review of nuclear safety approaches and is bringing a refocussing of R and D in the field. To support these efforts several new Euratom FP7 projects have been launched. The CESAM project focuses on the improvement of the ASTEC computer code. ASTEC is jointly developed by IRSN and GRS and is considered as the European reference code for Severe Accident Analyses since it capitalizes knowledge from the extensive Euro-pean R and D in the field. The project aims at the code's enhancement and extension for use in Severe Accident Management (SAM) analysis of the NPPs of Generation II-III presently under operation or foreseen in the near future in Europe, spent fuel pools included. The work reported here is concerned with the importance, for the further development of the code, of SAM strategies to be simulated. To this end, SAM strategies applied in the EU have been compiled. This compilation is mainly based on the public information made available in the frame of the EU ''stress tests'' for NPPs and has been complemented by information pro-vided by the different CESAM partners. The context of SAM is explained and the strategies are presented. The modelling capabilities for the simulation of these strategies in the current production version 2.0 of ASTEC are discussed. Furthermore, the requirements for the next version of ASTEC V2.1 that is supported in the CESAM project are highlighted. They are a necessary complement to the list of code improvements that is drawn from consolidating new fields of application, like SFP and BWR model enhancements, and from new experimental results on severe accident phenomena.

    The development and computational implementation of analytical expres­ sions for the low-order derivatives of electronic energy surfaces and other molecular properties has undergone rapid growth in recent years. It is now fairly routine for chemists to make use of energy gradient information in locating and identifying stable geometries and transition states. The use of second analytical derivative (Hessian or curvature) expressions is not yet routine, and third and higher energy derivatives as well as property (e.g., dipole moment, polarizability) derivatives are just beginning to be applied to chemical problems. This NATO Advanced Research Workshop focused on analyzing the re­ lative merits of various strategies for deriving the requisite analyti­ cal expressions, for computing necessary integral derivatives and wave­ function parameter derivatives, and for efficiently coding these expres­ sions on conventional scalar machines and vector-oriented computers.

    Full Text Available Interoperability is not a new area of effort at NATO level. In fact, interoperability and more specifi cally standardization, has been a key element of the Alliance’s approach to fi elding forces for decades. But as the security and operational environment has been in a continuous change, the need to face the new threats and the current involvement in challenging operations in Afghanistan and elsewhere alongside with the necessity to interoperate at lower and lower levels of command with an increasing number of nations, including non-NATO ISAF partners, NGOs, and other organizations, have made the task even more challenging. In this respect Interoperability Integration within NATO Defense Planning Process will facilitate the timely identifi cation, development and delivery of required forces and capabilities that are interoperable and adequately prepared, equipped, trained and supported to undertake the Alliance’s full spectrum of missions.

    Transients in containment systems of different scales (Phebus.FP containment, KAEVER vessel, Battelle Model Containment, LACE vessel and VVER-1000 nuclear power plant containment) involving thermal-hydraulic phenomena and aerosol behaviour, were simulated with the computer integral code ASTEC. The results of the simulations in the first four facilities were compared with experimental results, whereas the results of the simulated accident in the VVER-1000 containment were compared to results obtained with the MELCOR code. The main purpose of the simulations was the validation of the CPA module of the ASTEC code. The calculated results support the applicability of the code for predicting in-containment thermal-hydraulic and aerosol phenomena during a severe accident in a nuclear power plant.

    The 4-year JASMIN collaborative project (Joint Advanced Severe accidents Modelling and Integration for Na-cooled fast reactors), started in Dec.2011 in the frame of the 7. Framework Programme of the European Commission. It aims at developing a new European simulation code, ASTEC-Na, dealing with the primary phase of SFR core disruptive accidents. The development of a new code, based on a robust advanced simulation tool and able to encompass the in-vessel and in-containment phenomena occurring during a severe accident is indeed of utmost interest for advanced and innovative future SFRs for which an enhanced safety level will be required. This code, based on the ASTEC European code system developed by IRSN and GRS for severe accidents in water-cooled reactors, is progressively integrating and capitalizing the state-of-the-art knowledge of SFR accidents through physical model improvement or development of new ones. New models are assessed on in-pile (CABRI, SCARABEE etc...) and out-of pile experiments conducted during the 70's-80's and code-o-code benchmarking with current accident simulation tools for SFRs is also conducted. During the 2 and a half first years of the project, model specifications and developments were conducted and the validation test matrix was built. The first version of ASTEC-Na available in early 2014 already includes a thermal-hydraulics module able to simulate single and two-phase sodium flow conditions, a zero point neutronic model with simple definition of channel and axial dependences of reactivity feedbacks and models derived from SCANAIR IRSN code for simulating fuel pin thermo-mechanical behaviour and fission gas release/retention. Meanwhile, models have been developed in the source term area for in-containment particle generation and particle chemical transformation, but their implementation is still to be done. As a first validation step, the ASTEC-Na calculations were satisfactorily compared to thermal-hydraulics experimental

    Severe accident analysis of a reactor is an important aspect in the evaluation of source term. This in turn helps in emergency planning. An analysis has been carried out for VVER-1000 (V320) reactor following Large Break LOCA (loss of coolant accident) along with Station Blackout (SBO). Computer code ASTEC (jointly developed by IRSN, France, and GRS, Germany) is used for analyzing the transient. This integral code has been designed to be used as reference code for PSA2 studies. Severe accident analysis is carried out for an accident initiated by Large break LOCA along with SBO. Two cases have been analysed with the version ASTEC V1.2-rev1. In the first case hydro-accumulators are considered not available while the second case has been analysed with hydro accumulators. In this paper, ASTEC predictions have been studied for the in-vessel phase of the accident till vessel failure. The vessel failure was observed at 6979 s when accumulators were assumed not available. The vessel failure was quite delayed (19294 s) with operating accumulators. The hydrogen production was found to be very large (22% of total Zr inventory) in the case with accumulators compared to the case without accumulators (1.5% of total Zr inventory)

    The thermal load from the corium to the lower head vessel in the APR (Advanced Power reactor) 1400 during a small break loss of coolant accident (SBLOCA) without a safety injection (SI) has been evaluated using the ASTEC (Accident Source Term Evaluation Code) computer code, which has been developed as a part of the EU (European Union)-SARNET (Severe Accident Research NET work) program. The ASTEC results predict that the reactor vessel did not fail by using an ERVC, in spite of the large melting of the reactor vessel wall in a two-layer formation case of the SBLOCA in the APR1400. The outer surface conditions of the temperature and heat transfer coefficient are not effective on the vessel geometry change, which are preliminary results. A more detailed analysis of the main parameter effects on the corium behavior in the lower plenum is necessary to evaluate the IVR-ERVC in the APR1400, in particular, for a three-layer formation of the TLFW. Comparisons of the present results with others are necessary to verify and apply them to the actual IVR-ERVC evaluation in the APR1400

    This is an attempt at comparing two cell separators for plateletpheresis, namely the Fresenius AS.TEC 204 and Haemonetics MCS 3p, at a tertiary care center in India. Donors who weighed between 55-75 kg, who had a hematocrit of 41-43%, and platelet counts of 250x10(3)-400x10(3)/microl were selected for the study. The comparability of the donors who donated on the two cell separators were analysed by t-test independent samples and no significant differences were found (P>0.05). The features compared were time taken for the procedure, volume processed on the separators, adverse reactions of the donors, quality control of the product, separation efficiency of the separators, platelet loss in the donors after the procedure, and the predictor versus the actual yield of platelets given by the cell separator. The volume processed to get a target yield of >3x10(11) was equal to 2.8-3.2 l and equal in both the cell separators. Symptoms of citrate toxicity were seen in 4 and 2.5% of donors who donated on the MCS 3p and the AS.TEC 204, respectively, and 3 and 1% of donors, respectively, had vasovagal reactions. All the platelet products collected had a platelet count of >3x10(11); 90% of the platelet products collected on the AS.TEC 204 attained the predicted yield that was set on the cell separator where as 75% of the platelet products collected on the MCS 3p attained the target yield. Quality control of the platelets collected on both the cell separators complied with the standards except that 3% of the platelets collected on the MCS 3p had a visible red cell contamination. The separation efficiency of the MCS 3p was higher, 50-52% as compared to the 40-45% on the AS.TEC 204. A provision of double venous access, less adverse reactions, negligible RBC contamination with a better predictor yield of platelets makes the AS.TEC 204 a safer and more reliable alternative than the widely used Haemonetics MCS 3p.

    NATO will shortly revisit the question of its nuclear policy and posture as part of the ongoing deterrence and defense posture review (DDPR). This assessment of its nuclear requirements will be take place against the background of two parallel and potentially competing commitments: first, the general support for the goal of reducing and eventually eliminating nuclear weapons with the related question of how NATO should contribute to this goal; second, the commitment that in considering the role of nuclear weapons the priority for NATO members is the maintenance of solidarity and cohesion and the consequent determination that decisions on nuclear policy will be taken by the Alliance collectively. There are forcefully expressed arguments on both sides of the debate over whether to maintain or eliminate the remaining arsenal of U.S. nuclear weapons assigned to NATO.

    NATO will shortly revisit the question of its nuclear policy and posture as part of the ongoing deterrence and defense posture review (DDPR). This assessment of its nuclear requirements will be take place against the background of two parallel and potentially competing commitments: first, the general support for the goal of reducing and eventually eliminating nuclear weapons with the related question of how NATO should contribute to this goal; second, the commitment that in considering the role of nuclear weapons the priority for NATO members is the maintenance of solidarity and cohesion and the consequent determination that decisions on nuclear policy will be taken by the Alliance collectively. There are forcefully expressed arguments on both sides of the debate over whether to maintain or eliminate the remaining arsenal of U.S. nuclear weapons assigned to NATO. On the one hand, they provide coupling, transatlantic links, military capabilities against an uncertain future, and risk and burden sharing. On the other, some allies see benefits to further reductions in the remaining arsenal in the cause of global disarmament. This study presents first the questions and issues for NATO and the future alternatives for NATO nuclear policy.

    Highlights: • Short overview of the models included in the ASTEC MCCI module. • MEDICIS/CPA coupled calculations for a generic CANDU6 reactor. • Two cases taking into account different pool/concrete interface models. - Abstract: In case of a hypothetical severe accident in a nuclear power plant, the corium consisting of the molten reactor core and internal structures may flow onto the concrete floor of containment building. This would cause an interaction between the molten corium and the concrete (MCCI), in which the heat transfer from the hot melt to the concrete would cause the decomposition and the ablation of the concrete. The potential hazard of this interaction is the loss of integrity of the containment building and the release of fission products into the environment due to the possibility of a concrete foundation melt-through or containment over-pressurization by the gases produced from the decomposition of the concrete or by the inflammation of combustible gases. In the safety assessment of nuclear power plants, it is necessary to know the consequences of such a phenomenon. The paper presents an example of application of the ASTECv2 code to a generic CANDU6 reactor. This concerns the thermal-hydraulic behaviour of the containment during molten core–concrete interaction in the reactor vault. The calculations were carried out with the help of the MEDICIS MCCI module and the CPA containment module of ASTEC code coupled through a specific prediction–correction method, which consists in describing the heat exchanges with the vault walls and partially absorbent gases. Moreover, the heat conduction inside the vault walls is described. Two cases are presented in this paper taking into account two different heat transfer models at the pool/concrete interface and siliceous concrete. The corium pool configuration corresponds to a homogeneous configuration with a detailed description of the upper crust.

    Last years the interest in sodium-cooled fast reactors (SFR) has been fostered worldwide by the search for higher nuclear energy sustainability. This has been reflected in the various international initiatives like GEN-IV International Forum, INPRO or ESNII platforms. At the same time, innovative nuclear reactor designs, particularly SFR, are aiming at even higher safety standards than current LWRs. A proof of it is the consideration of severe accidents since the earliest stages of reactor design. commonalities of LWR and SFR severe accident scenarios suggest that some of the knowledge achieved in the LWR arena might be applicable to some extent to SFRs. This is the spirit underneath of the EU-JASMIN project, which generic goal is developing the ASTEC-Na code from the LWR ASTEC platform. This will entail to t extend and adapt some existing models as well as to implement new ones in all the areas covered, from neutronics and pin thermo-mechanics and pin thermo-mechanics to the in-containment source term behavior by these, going through the indispensable Na thermal-hydraulics.

  8. NATO strategy in a new world order

    1992-01-01

    This paper reports that the most immediate threat to Western Europe during the cold ware was the specter of Soviet military superiority looming from the East, proscribing Western political and economic freedom. NATO and the link to U.S. military power deterred political intimidation as well as a less probable military thrust into Central Europe. But these threat have faded under Mikhail Gorbachev, replaced by revolutions in Eastern Europe, the dissolution of the Warsaw Pact, receding Soviet military power, German unification, and the stirring of political and economic freedom nurtured by the West. These events are linked directly to the Gorbachev domestic revolution, a revolution that depends not only on domestic change, but also on political-economic integration with the West and dramatic shifts from defense to domestic investment. New Soviet military thinking, arms control, and unilateral cuts in conventional force structure and dramatic in themselves. But when projected on a new map of Europe, these events call for a major reexamination of NATO military strategy and the future role of the U.S. armed forces in a revised organization. A new strategy for NATO has been quietly taking shape since 1989, the debate often muffled by more dramatic events in the Soviet Union and more recently by war in the Persian Gulf. By the spring of 1991, the broad outlines of a new NATO within a radically new European security regime began to emerge. This chapter assesses both the emerging new strategy and the larger European security environment in which it will evolve

    2005-01-01

    The PHEBUS Fission Product (FP) programme was initiated in 1988 after major severe reactor accidents (at Three Mile Island and Chernobyl). The main objective of the programme is to study the release, transport and retention of fission products in an in-pile facility under severe accident conditions in a LWR. This paper covers the FPT 1 experiment description and modelling by the ASTEC code. The main calculated events, the temperature evolution at the middle part of the test bundle, the state of the bundle degradation at the end of calculation and the calculated Hydrogen production are presented and discussed. The obtained results from the ASTEC code calculation show a good agreement between experimental and calculated results. The calculated Hydrogen production is slightly overestimated in comparison with the experimental results

    1988-01-01

    Nuclear weapons are for NATO both the primary instrument for deterring a nuclear attack and the fall-back option if, in the event of a conventional assault, NATO's non-nuclear defence forces cannot hold. The dilemma of depending upon potentially self-destructive nuclear responses if deterrence fails and defence falters has always haunted NATO strategy, but after the Soviets achieved nuclear parity with the United States, this dilemma became more intensely perceived. Now the credibility, viability, acceptability, sensibility and morality of nuclear weapons for deterrence and defence are increasingly at issue. As a result, an increasing variety of non-nuclear (conventional) alternatives are being advanced to replace or supplement nuclear deterrence for the Alliance. The thrust of the author of this paper remarks is to attempt to apply the definitions, requirements, and other key conceptual distinctions of nuclear deterrence found in the body of western strategic literature to three categories of non-nuclear alternatives currently in vogue: strengthened conventional forces; deployment of new, high-technology non-nuclear weapons; and adoption of an offensive manoeuvre strategy. Let me, therefore, begin by listing the basic definitions, concepts and apparent requirements of deterrence which the deterrence theory literature offers

The meeting was sponsored by the Special Panel on Systems Sciences of the NATO Scientific Affairs Division. In proposing this meeting the Symposium Directors built upon several preceding NATO conferences in the general area of personnel systems, manpower modelling, and organization. The most recent NATO Conference, entitled "Manpower Planning and Organization Design," was held in Stresa, Italy in 1977. That meeting was organized to foster research on the interrelationships between programmatic approaches to personnel planning within organizations and behavioral science approachs to organization design. From that context of corporate planning the total internal organizational perspective was the MACRO view, and the selection, assignment, care and feeding of the people was the MICRO view. Conceptually, this meant that an integrated appr...

    Full Text Available Canada, as one of the founding countries, plays an active role in NATO since its establishment and till the modern stage. Canadian military forces participate in international peacekeeping operations, counter­terrorism and maintaining security in the transatlantic area. Despite the close relationship with the US as a military, political and economic areas, Canada has always tried to conduct an independent policy within NATO. Canada national interests and NATO influence expand overlapping on the Arctic region deserves special attention. Canada’s position on the role of NATO in the Arctic rather contradictory. Canada fears the growing influence in the Arctic region of the NATO member countries, which are not the Arctic states as in the case of Britain. Canada has long been promoting the idea of the alliance’s transformation into the global organization like the United Nations Organization, which set a goal to provide security around the world. In fact, Canada seeks the creation of a «world policeman» who has modern special forces intended to participate in conflicts in different parts of the world. Also there is another scenario ­ the preservation of NATO as a «Eurocentric hybrid» with the former focusing on European security.

    In the event of an accident occurring in a nuclear power plant (NPP), being able to predict the amount of released radioactive substances in the environment is of prime importance. Depending on the severity of the accident, it can be necessary to quickly and efficiently protect the population and the surrounding environment from the associated radiological consequences. In France, the IRSN Emergency Technical Centre provides a technical support in decision making in case of a nuclear accident. The main objectives are to evaluate and predict the plant behaviour and radioactive releases during the accident. Different types of complementary tools are used: expert assessments, pre-calculated databases, simulation tools, etc. In the case of Steam Generator Tube Rupture (SGTR) accidents that may lead to significant radioactive releases to the atmosphere through the steam generator relief valves, IRSN is currently improving the simulation tools for diagnosis in crisis management. The objective is to adapt the thermal-hydraulic and FP behaviour modules of the severe accident integral code ASTEC V2.0, jointly developed by IRSN and its German counterpart GRS, to crisis management requirements. These requirements impose a fast running, highly reliable (accurate physical results), flexible and simple tool. This paper summarizes the results of the benchmarks between the ASTEC V2.0 thermal-hydraulic module and the CATHARE 2 (V2.5) French reference thermal-hydraulics code on several SGTR scenarios both for PWR 900 and 1300 MWe, with a particular emphasis on the computational time and physical models assessment. The overall agreement between both codes is good on the primary and secondary circuit thermal-hydraulic parameters. Moreover, the reliability and fast computational time of the thermal-hydraulic module of ASTEC V2.0 code appeared very satisfactory and in accordance with the requirements of an emergency tool.

    Within the framework of the European JASMIN project, the ASTEC-Na code is being developed for safety analysis of severe accidents in SFR. In the first phase of validation of the ASTEC-Na fuel thermo-mechanical models three in-pile tests conducted in the CABRI experimental reactor have been selected to be analysed. We present here the preliminary results of the simulation of two Transient Over Power tests and one power ramp test (AGS0, LT2 and E9, respectively) where no pin failure occurred during the transient. We present the comparison of ASTEC-Na results against experimental data and other safety code results for the initial steady state conditions prior to the transient onset as well as for the fuel pin behaviour during the transients.

    Nanomaterials and their associated technologies hold promising opportunities for the development of new materials and applications in a wide variety of disciplines, including medicine, environmental remediation, waste treatment, and energy conservation. However, current information regarding the environmental effects and health risks associated with nanomaterials is limited and sometimes contradictory. This article summarizes the conclusions of a 2008 NATO workshop designed to evaluate the wide-scale implications (e.g., benefits, risks, and costs) of the use of nanomaterials on human health and the environment. A unique feature of this workshop was its interdisciplinary nature and focus on the practical needs of policy decision makers. Workshop presentations and discussion panels were structured along four main themes: technology and benefits, human health risk, environmental risk, and policy implications. Four corresponding working groups (WGs) were formed to develop detailed summaries of the state-of-the-science in their respective areas and to discuss emerging gaps and research needs. The WGs identified gaps between the rapid advances in the types and applications of nanomaterials and the slower pace of human health and environmental risk science, along with strategies to reduce the uncertainties associated with calculating these risks.

  6. Status of emergency spray modelling in the integral code ASTEC

    International Nuclear Information System (INIS)

    Plumecocq, W.; Passalacqua, R.

    2001-01-01

    Containment spray systems are emergency systems that would be used in very low probability events which may lead to severe accidents in Light Water Reactors. In most cases, the primary function of the spray would be to remove heat and condense steam in order to reduce pressure and temperature in the containment building. Spray would also wash out fission products (aerosols and gaseous species) from the containment atmosphere. The efficiency of the spray system in the containment depressurization as well as in the removal of aerosols, during a severe accident, depends on the evolution of the spray droplet size distribution with the height in the containment, due to kinetic and thermal relaxation, gravitational agglomeration and mass transfer with the gas. A model has been developed taking into account all of these phenomena. This model has been implemented in the ASTEC code with a validation of the droplets relaxation against the CARAIDAS experiment (IPSN). Applications of this modelling to a PWR 900, during a severe accident, with special emphasis on the effect of spray on containment hydrogen distribution have been performed in multi-compartment configuration with the ASTEC V0.3 code.

    2013-01-01

    The ASTEC/V2.0 computer code was used to simulate a hypothetical severe accident sequence in the nuclear power plant Krsko, a 2-loop pressurized water reactor (PWR) plant. ASTEC is an integral code jointly developed by Institut de Radioprotection et de Surete Nucleaire (IRSN, France) and Gesellschaft fuer Anlagen- und Reaktorsicherheit (GRS, Germany) to assess nuclear power plant behaviour during a severe accident. The analysis was conducted in 2 steps. First, the steady state calculation was performed in order to confirm the applicability of the plant model and to obtain correct initial conditions for the accident analysis. The second step was the calculation of the station blackout accident with a leakage of the primary coolant through degraded reactor coolant pump seals, which was a small LOCA without makeup capability. Two scenarios were analyzed: one with and one without the auxiliary feedwater (AFW). The latter scenario, without the AFW, resulted in earlier core damage. In both cases, the accident ended with a core melt and a reactor pressure vessel failure with significant release of hydrogen. In addition, results of the ASTEC calculation were compared with results of the RELAP5/SCDAPSIM calculation for the same transient scenario. The results comparison showed a good agreement between predictions of those 2 codes. (orig.)

    Phonons are always present in the solid state even at an absolute temperature of 0 K where zero point vibrations still abound. Moreover, phonons interact with all other excitations of the solid state and, thereby, influence most of its properties. Historically experimental information on phonon transport came from measurements of thermal conductivity. Over the past two decades much more, and much more detailed, information on phonon transport and on many of the inherent phonon interaction processes have come to light from experiments which use nonequilibrium phonons to study their dynamics. The resultant research field has most recently blossomed with the development of ever more sophisticated experimental and theoretical methods which can be applied to it. In fact, the field is moving so rapidly that new members of the research community have difficulties in keeping up to date. This NATO Advanced Study Institute (ASI) was organized with the objective of overcoming the information barrier between those expert...

    1994-01-01

    In a special meeting of Foreign and Defense Ministers, the NATO alliance on 12 December 1979 decided to modernize its long range theater nuclear forces (LRTNF) through the deployment in Europe of 572 Pershing II and ground launched cruise missiles (GLCM). This decision was accompanied by an offer from the US to the U.S.S.R. to negotiate limitations on these LRTNF which would be global, equal, and verifiable. The story of NATO's dual-track decision as well as the INF Treaty is well chronicled. What is missing is a detailed study of the processes within the US government and the NATO alliance by which the LRTNF decisions were made. The role that analysis played, and the lessons that can be drawn for future policies on NATO's theater nuclear forces are discussed

Some of these materials are unusual or exotic, while some are modifications of materials used daily for other purposes: biological, chemical, radiological, nuclear and explosive. These materials pose a safety challenge for first responders, slowing the response and potentially killing scarce trained personnel. This book provides information about how leading agencies across the NATO membership are preparing to confront and respond to terrorists deploying Weapons of Mass Destruction (WMD), Weapons of Mass Killing (WMK) and Weapons of Mass Disruption (WMDi). Based on contributions by experts from NATO member states, Israel and the Russian Federation, this book offers information on fourth generation warfare as a new challenge to first responders. It also pr...

  16. NATO Advanced Research Workshop on Earth Rotation : Solved and Unsolved Problems

    CERN Document Server

    1986-01-01

    The idea for organl.zl.ng an Advanced Research Workshop entirely devoted to the Earth rotation was born in 1983 when Professor Raymond Hide suggested this topic to the special NATO panel of global transport mechanism in the Geosciences. Such a specialized meeting did not take place since the GEOP research conference on the rotation of the Earth and polar motion which was held at the Ohio State University (USA) in 1973. In the last ten years, highly precise measurements of the Earth's rotation parameters and new global geophysical data have become available allowing major advance to be made in the under­ standing of the various irregularities affecting the Earth's rotation. The aim of the workshop was to bring together scientists who have made important contributions in this field during the last decade both at the observational and geophysical interpretation levels. The confe­ rence was divided into four main topics. The first session was dedicated to the definition, implementation and maintenance of the te...

    2010-01-01

    The purpose of this NATO workshop is to contribute to the critical assessment of how to prepare for a new national nuclear energy program, and to make recommendations for future action. In addition, our goal is to promote close working relationships between technical people from different countries and with different professional expertise. In particular, the countries that are involved in this workshop are those from NATO and those from the Partner countries such as those in the Commonwealth of Independent States. A NATO workshop is not an international conference or symposium but rather a forum for advanced level, intensive discussions. The presentations are part of the growing font of knowledge on the subject of how to develop a national nuclear energy program. It is heard about the infrastructure that is needed and how the IAEA and countries with existing experience are helping to provide that infrastructure to those working toward a nuclear energy program. It is heard about the experiences of several countries embarking on new nuclear development, with an emphasis on how progress is being made in Armenia. It is also heard about the potential for using small and medium size reactors; something not being pursued by the countries with large nuclear programs

    1980-01-01

    The idea of a NATO Science Committee Institute on "Materials for Advanced Batteries" was suggested to JB and DWM by Dr. A. G. Chynoweth. His idea was to bring together experts in the field over the entire spectrum of pure research to applied research in order to familiarize everyone with potentially interesting new systems and the problems involved in their development. Dr. M. C. B. Hotz and Professor M. N. Ozdas were instrumental in helping organize this meeting as a NATO Advanced Science Institute. An organlzlng committee consisting of the three of us along with W. A. Adams, U. v Alpen, J. Casey and J. Rouxel organized the program. The program consisted of plenary talks and poster papers which are included in this volume. Nearly half the time of the conference was spent in study groups. The aim of these groups was to assess the status of several key aspects of batteries and prospects for research opportunities in each. The study groups and their chairmen were: Current status and new systems J. Broadhead Hig...

    2015-06-01

    Full Text Available The conclusion of a conflict, called by some American analysts as “America’s Longest War”, after the withdrawal of the majority of NATO military forces, requires a careful analysis of the conditions and security environment that ISAF mission, International Security Afghan Forces, leaves as legacy to the Afghan military forces. The transfer of authority towards a strong government, recognized by most Afghan provinces, and benefiting from the support of national military forces able to cope with terrorist and insurgent threats on its own, are the minimum and necessary conditions leading the country towards a stable and secure environment and towards a sustainable development. Given these realities, any approach on the consequences of the transition towards self-sustainable governance becomes interesting and timely for any military political study. These are the prospects that we propose in our paper.

  2. Containment Modelling with the ASTEC Code

    International Nuclear Information System (INIS)

    Sadek, Sinisa; Grgic, Davor

    2014-01-01

    ASTEC is an integral computer code jointly developed by Institut de Radioprotection et de Surete Nucleaire (IRSN, France) and Gesellschaft fur Anlagen-und Reaktorsicherheit (GRS, Germany) to assess the nuclear power plant behaviour during a severe accident (SA). It consists of 13 coupled modules which compute various SA phenomena in primary and secondary circuits of the nuclear power plants (NPP), and in the containment. The ASTEC code was used to model and to simulate NPP behaviour during a postulated station blackout accident in the NPP Krsko, a two-loop pressurized water reactor (PWR) plant. The primary system of the plant was modelled with 110 thermal hydraulic (TH) volumes, 113 junctions and 128 heat structures. The secondary system was modelled with 76 TH volumes, 77 junctions and 87 heat structures. The containment was modelled with 10 TH volumes by taking into account containment representation as a set of distinctive compartments, connected with 23 junctions. A total of 79 heat structures were used to simulate outer containment walls and internal steel and concrete structures. Prior to the transient calculation, a steady state analysis was performed. In order to achieve correct plant initial conditions, the operation of regulation systems was modelled. Parameters which were subjected to regulation were the pressurizer pressure, the pressurizer narrow range level and steam mass flow rates in the steam lines. The accident analysis was focused on containment behaviour, however the complete integral NPP analysis was carried out in order to provide correct boundary conditions for the containment calculation. During the accident, the containment integrity was challenged by release of reactor system coolant through degraded coolant pump seals and, later in the accident following release of the corium out of the reactor pressure vessel, by the molten corium concrete interaction and direct containment heating mechanisms. Impact of those processes on relevant

    Full Text Available Considering that NATO, EU and other organizations tend to include public diplomacy elements in their official documents and strategies, we can say that states are no longer the exclusive actors in this field. Through this paper, I seek to identify some similarities and differences between NATO and EU’s public diplomacy. In this research I will also study how much of their soft power capabilities these organizations use, if they are used in order to influence rather internal than external audiences and if we can talk about elements of public diplomacy with involvements for development. Beyond these aspects, I will take into account the fact that Philip Seib claims that NATO should focus on using soft power in order to justify its hard power and try to see if there are differences in the goals that NATO and the EU target to reach through the implementation of some public diplomacy strategies.

  6. NATO Advanced Study Institute on Recent Advances in the Modeling of Hydrologic Systems

    CERN Document Server

    O’Connell, P

    1991-01-01

    Modeling of the rainfall-runoff process is of both scientific and practical significance. Many of the currently used mathematical models of hydrologic systems were developed a genera­ tion ago. Much of the effort since then has focused on refining these models rather than on developing new models based on improved scientific understanding. In the past few years, however, a renewed effort has been made to improve both our fundamental understanding of hydrologic processes and to exploit technological advances in computing and remote sensing. It is against this background that the NATO Advanced Study Institute on Recent Advances in the Modeling of Hydrologic Systems was organized. The idea for holding a NATO ASI on this topic grew out of an informal discussion between one of the co-directors and Professor Francisco Nunes-Correia at a previous NATO ASI held at Tucson, Arizona in 1985. The Special Program Panel on Global Transport Mechanisms in the Geo-Sciences of the NATO Scientific Affairs Division agreed to sp...

    1982-01-01

    From August 4 to 8, 1980, the Science Committee of the North Atlantic Treaty Organization (NATO) sponsored the symposium, "Women and the World of Work," which was held at the Hotel Sintra Estoril in the coastal area south of Lisbon, Portugal. This symposium hatl been "in progress" since 1977 when the idea to prepare a proposal for a NATO­ sponsored symposium on the topic of women and the military was first suggested by Dr. Walter Wilkins, then Scientific Director of the Naval Health Research Center, San Diego, California. At that time and during the previous 5 years, increasing numbers of women were being recruited into military service not only in the United States but also in several NATO-allied countries. Few research projects on the utilization of women in the military had been reported in the scientific literature with the exception of work conducted at the University of Chicago and Naval Health Research Center. Several investigators, however, were identified who had recently initiated research in this ...

  13. NATO Advanced Research Workshop on Applications of Picosecond Spectroscopy to Chemistry

    CERN Document Server

    1984-01-01

    With the development of lasers that can generate light 11 14 pulses ranging from 10- - 10- sec duration, and capable of 13 peak powers in excess of 10 watts scientists have been able to investigate the interactions of light with matter in a time and power domain not previously possible. These ultrashort laser pulses provide a powerful tool for the study of chemical phenomena at the most fundamental level. Many of the elementary processes of importance in chemistry including energy dissipa­ tion, molecular motions, structural and chemical changes occur on a very short time scale and thus require special approaches. Th~ use of ultrashort laser pulses to perturb and to probe systems of interest affords a direct approach to the time reso­ lution of very rapid chemical phenomena. It was recognition of the impact of these relatively new approaches to chemical phenomena that motivated NATO to sponsor a meeting on the applications of picosecond spectroscopy in chemistry. The primary aim of the NATO workshop was to ...

    It is well known that DU (depleted uranium) weaponry was extensively used during the 'Desert Storm' operation in Iraq. There is no doubt that NATO used DU ammunition in Bosnia in 1994 and 1995. It is also common knowledge that many NATO armies are equipped with DU ammunition in various calibers (from 20 up to 155 mm) as a standard part of certain weapon systems. These facts, as a result of literature research, as well as Yugoslav Army (YA) intelligence data on the eve of the aggression clearly showed that NATO most probably would use DU ammunition. (author)

It is built on the logic that military operations do not stand alone, but are inherently deep-rooted in the strategic context provided by other strategic instruments of power...... such as the political/diplomatic, economic, and civil society. As effects have to be generated within this multifaceted context, common sense dictated that effect-based thinking for military plans and operations has to become intrinsically tied to the comprehensive approach.

    In comparison with other countries Yugoslavia is very rich by great genetic, species and ecosystem diversity. The territory of Yugoslavia is 102173 km 2 , it is only 0,07% of world's land and 2,1% of the European continent. We have 6 biomes, 5 of the 12 terrestrial biomes of the world and biome of the sea as sixth biome. According to the international criteria the territory of Yugoslavia is one of the six European and one of the 153 world's centers of biological diversity. In period from March 24. until June 10. 1999. NATO carried out more than 35000 assaults against the Yugoslavia. All these have lasting consequences on the health of the entire population and the environment with prominent transboundary effects. Many species have become extinct due to the NATO bombings, and wildlife has started migrating and abandoning its natural habitat. The necessity of future scientifically based monitoring is evident and also very strong protection of biodiversity. (author)

    2010-08-01

    In the frame of the project RS1180 funded by the German Federal Ministry for Economics and Technology (BMWi) calculations have been carried out with the integral code ASTEC V1.33 p3 developed by GRS for two postulated accidents in a nuclear power plant with KONVOI type a pressurized water reactor and compared to calculations with MELCOR 1.8.6 YU. Major objective was to assess the capability of ASTEC for application in level 2 probabilistic safety analyses (PSA). In particular, it was investigated to which extent ASTEC is able to perform such integral calculations meeting criteria with regard to both reasonable calculation time and specific boundary conditions necessary for PSA analyses. Two exemplary accidents were selected: - A transient with loss of steam generator feed water, - A small break loss of coolant accident (50 cm 2 ) in the cold leg of the coolant line connected to the pressurizer. In principle, the results demonstrate the capability of ASTEC V1.33 to carry out such PSA level 2 calculations. In addition, it has to be noted that for both ASTEC and MELCOR the requirements in view of the quality of the results leads to prolonged calculation times due to more detailed nodalisations of the whole plant. This is valid for the core region as well as for the primary circuit and for the containment. Consequently, calculation times in the order of one day to two weeks are accomplished, thereby excluding extensive parameter analyses in order to assess the sensitivity of the calculation results. Concerning the quality of the results a good agreement can be stated between ASTEC and MELCOR results in terms of global data. In detail some results are sensitive to user effects. Here, the nodalisation seems to be of major influence besides differences in modeling specific phenomena. The comparison suggests that in particular the influence of the nodalisation defined by the user and depending on the user's experience should be carefully evaluated. Since some

We show that when the maximal quantum Fisher information matrix exists, it can be directly obtained from the underlying dynamics. Examples are then provided to demonstrate the usefulness of the maximal quantum Fisher information matrix by deriving various trade-off relations in multi-parameter quantum estimation and obtaining the bounds for the scalings of the precision limit.

    2015-12-01

    The present report is a Technical Report within the research project ''ASMO'', funded by the German Federal Ministry of Economics and Technology (BMWi 1501433) and projected at the Reactor Simulation and Safety Group, Chair of Energy Systems and Energy Economics (LEE) at the Ruhr-Universitaet Bochum (RUB). The project deals with the analysis of the model basis of the Accident Source Term Evaluation Code (ASTEC). This report focuses on the containment part of ASTEC (CPA) and presents the simulation results of the experiment TH20.7. The experimental series TH20 was performed in the test vessel THAI (Thermal-hydraulics, Aerosols, Iodine) to investigate the erosion of a helium layer by a blower generated air jet. Helium is used as a substitute for hydrogen. In the experiment TH20.7 a light-gas layer is established and eroded by a momentum driven jet. The simulation of momentum driven jets is challenging for CPA because there is no model to simulate the kinetic momentum transfer. Subject of this report is the analysis of the capability of the code with the current model basis to model momentum driven phenomena. The jet is modelled using virtual ventilation systems, so called FAN-Systems. The FAN-Systems are adapted to the erosion velocity. The simulation results are compared to the experimental results and a basic calculation using FAN-Systems without any adjustments. For further improvement, different variation calculations are performed. At first, the vertical nodalization is refined. Subsequently, the resistance coefficients are adjusted to support the jet flow pattern and the number of the FAN-Systems is reduced. The analysis shows that the simulation of a momentum driven light-gas layer erosion is possible using adjusted FAN-Systems. A fine selected vertical nodalization and adaption of the resistance coefficients improves the simulation results.

    Safety assessment of water-cooled nuclear reactors encompasses potential severe accidents where, in particular, the release of fission products (FPs) and actinides into the reactor coolant system (RCS) is evaluated. The ELSA module is used in the ASTEC integral code to model all releases into the RCS. A wide variety of experiments is used for validation: small-scale CRL, ORNL and VERCORS tests; large-scale Phebus-FP tests; etc. Being a tool that covers intact fuel and degraded states, ELSA is being improved maximizing the use of information from degradation modelling. Short-term improvements will include some treatment of initial FP release due to intergranular inventories and implementing models for release of additional structural materials (Sn, Fe, etc.).

    Barbara, Bernard; Sawatzky, G; Stamp, P. C. E

    2008-01-01

    This book is based on some of the lectures during the Pacific Institute of Theoretical Physics (PITP) summer school on "Quantum Magnetism", held during June 2006 in Les Houches, in the French Alps. The school was funded jointly by NATO, the CNRS, and PITP, and entirely organized by PITP. Magnetism is a somewhat peculiar research field. It clearly has a quantum-mechanical basis – the microsopic exchange interactions arise entirely from the exclusion principle, in conjunction with respulsive interactions between electrons. And yet until recently the vast majority of magnetism researchers and users of magnetic phenomena around the world paid no attention to these quantum-mechanical roots. Thus, eg., the huge ($400 billion per annum) industry which manufactures hard discs, and other components in the information technology sector, depends entirely on room-temperature properties of magnets - yet at the macroscopic or mesoscopic scales of interest to this industry, room-temperature magnets behave entirely classic...

  16. Assessment of the integral code ASTEC with respect to the late in-vessel phase of core degradation

    International Nuclear Information System (INIS)

    D'Alessandro, Christophe; Starflinger, Joerg

    2014-01-01

    The integral code ASTEC is being developed jointly by GRS and IRSN as the European reference code for severe accidents. In the EU project CESAM it is foreseen to assess the capabilities of ASTEC to deal with a broad range of reactor designs (PWR, BWR, VVER, CANDU, Gen III+, etc.) and especially to model and capture the effect of severe accident mitigation measures. This requires a physically sound and sufficiently accurate modelling of the processes and phenomena that govern the course of the accident, and the modelling has to be validated to a sufficient extent. Concentrating on the in-vessel aspects of severe accidents, the present paper addresses these requirements by presenting results of ASTEC calculations for relevant experiments that cover the major physical phenomena during core degradation (melting and relocation of the fuel, oxidation, molten corium pool formation and its coolability in the lower plenum once it slumped from the core region). The assessment of models for bundle degradation is based on CORA (13 and W2). CORA represented a bundle of non-irradiated, electrically heated UO 2 -rods. Melt progression in strongly degraded geometry is addressed in the PHEBUS-FTP4 experiment carried out with irradiated fuel in debris bed configuration. The validation of molten pool modelling is based on BALI and RASPLAV-Salt experiments. The BALI-facility consists of a full-scale slice of lower plenum (allowing experiments at prototypical Rayleigh numbers) and utilizes uniformly heated water as simulant for corium. The RASPLAV experiments use a scaled-down slice of the lower head. Use of non-eutectic molten salt as simulant should address the effect of a significant solidification range typical for real corium. Calculation results of ASTEC are discussed in comparison with experimental measurements. Further, questions concerning the extrapolation of findings from validation to reactor application are critically discussed, concerning e.g. choice of model parameters

    The recent generation in the laboratory of phase squeezed and intensity squeezed light beams has brought to fruition the theoretical predictions of such non-classical phenomena which have been made and developed in recent years by a number of workers in the field of quantum optics. A vigorous development is now underway of both theory and experiment and the first measurements have been coi:Jfirmed and extended already in some half dozen laboratories. Although the fields of application of these novellight sources are as yet somewhat hazy in our minds and some inspired thinking is required along these lines, the pace and excitement of the research is very clear. It is to he hoped that the new possibilities of: making measurements below the quantum shot noise lirnit which is made possible by these squeezed states of light willlead to further fundamental advances in the near future.

    Full Text Available After the collapse of the bipolar international order, NATO has been focused on its desire to eradicate Cold War divisions and to build good relations with Russia. However, the security environment, especially in Europe, is still dramatically changing. The NATO Warsaw Summit was focused especially on NATO’s deteriorated relations with Russia that affect Europe’s security. At the same time, it looked at bolstering deterrence and defence due to many concerns coming from eastern European allies about Russia’s new attitude in international relations. The Allies agreed that a dialogue with Russia rebuilding mutual trust needs to start. In the times when Europe faces major crisis from its southern and south-eastern neighbourhood - Western Balkan countries, Syria, Libya and Iraq - and other threats, such as terrorism, coming from the so-called Islamic State, causing migration crises, it is necessary to calm down relations with Russia. The article brings out the main purpose of NATO in a transformed world, with the accent on Europe, that is constantly developing new security conditions while tackling new challenges and threats.

  3. NATO International Conference on Applied General Systems Research : Recent Developments and Trends

    CERN Document Server

    1978-01-01

    This volume consists of a selection of papers presented at the International Conference on Applied General Systems Research: Recent Developments and Trends which was held on the campus of the State University of New York at Binghamton in August 15-19, 1977, under the sponsorship of the Special Panel on Systems Science of the NATO Scientific Affairs Division. General systems research is a fairly new field which has been developing in the course of the last two or three decades. In my op~n10n, it can be best described as a movement which involves the study of all structural and context independent aspects of problem solving. As such, it is cross-disciplinary in nature and, in this sense, it might seem similar to mathematics. There is a consid­ erable difference, however, between the two. While pure mathe­ matics is basically oriented to the development of various axiomatic theories, regardless of whether or not they have any real world meaning, applied mathematics explores the applicability of some of these t...

    The NATO Advanced Research Workshop "Painleve Transcendents, their Asymp­ totics and Physical Applications", held at the Alpine Inn in Sainte-Adele, near Montreal, September 2 -7, 1990, brought together a group of experts to discuss the topic and produce this volume. There were 41 participants from 14 countries and 27 lectures were presented, all included in this volume. The speakers presented reviews of topics to which they themselves have made important contributions and also re­ sults of new original research. The result is a volume which, though multiauthored, has the character of a monograph on a single topic. This is the theory of nonlinear ordinary differential equations, the solutions of which have no movable singularities, other than poles, and the extension of this theory to partial differential equations. For short we shall call such systems "equations with the Painleve property". The search for such equations was a very topical mathematical problem in the 19th century. Early work concent...

    Highlights: • The I 2 transport in a multi-compartment vessel was analysed. • ASTEC and MELCOR codes were employed. • Same nodalisation for the code-to-code comparison. • The I 2 concentrations were quite well simulated in ASTEC. • Numerical issues on MELCOR. - Abstract: This work is related to the application of the ASTEC V2.0R3p1 and MELCOR V2.1.4803 codes to the analysis of the THAI Iod-11 and Iod-12 containment tests characterised by an iodine release. The main scope of these two tests was to investigate the steel interaction on dry and wet surfaces, with an interaction supposed to be a two-steps process: an initial faster and reversible physisorption followed by a slower, and irreversible, chemisorption of the physisorbed I 2 . The aim of the present work is to highlight advancements and limitations of the current ASTEC and MELCOR code versions respect to the older code versions employed during the European SARNET projects. The investigation was carried out as a code-to-code comparison vs. the experimental THAI data, focusing on the evaluation of the code models treating the iodine behaviour. A similar spatial nodalisation was employed for both codes. As main result, ASTEC had shown an overall good agreement compared to the iodine related experimental data while, on contrary, MELCOR had shown poor results, probably due to unsolved numerical issues and unsatisfactory iodine modellisation

    The French Institut de Radioprotection et de Surete Nucleaire (IRSN) is performing a level 2 Probabilistic Safety Assessment (PSA-2) on the French 1300 MWe PWRs. This PSA-2 study is relying on the ASTEC integral computer code, jointly developed by IRSN and GRS (Germany). In order to assess the reliability and the quality of physical results of the ASTEC V1.3 code as well as the PWR 1300 MWe reference input deck, a wide-ranging series of comparisons with the French best-estimate thermal-hydraulic code CATHARE 2 V2.5 has been performed on 14 different severe-accident scenarios. The present paper details 4 out of the 14 studied scenarios: a 12-in. cold leg Loss of Coolant Accident (LOCA), a 2-tube Steam Generator Tube Rupture (SGTR), a 12-in. Steam Line Break (SLB) and a total Loss of Feed Water scenario (LFW). The thermal-hydraulic behavior of the primary and secondary circuits is thoroughly investigated and compared to the CATAHRE 2 V2.5 results. The ASTEC results of the core degradation phase are also presented. Overall, the thermal-hydraulic behavior given by the ASTEC V1.3 is in very good agreement with the CATHARE 2 V2.5 results.

Both child and adult burn injury victims were enrolled into a qualitative study conducted using focus group discussion. Haddon’s matrix was used to develop an interview guide and also through the analysis phase.Results: The main analysis clusters were pre-event level/human (including risky behaviors, belief and cultural factors, and knowledge and education, pre-event level/object, pre-event phase/environment and event and post-event phase (including fire control, emergency scald and burn wound management, traditional remedies, medical consultation, and severity indicators. This research gave rise to results that are possibly useful both for future injury research and for designing burn injury prevention plans.Conclusion: Haddon’s matrix is applicable in a qualitative research methodology both at data collection and data analysis phases. The study using Haddon’s matrix through a qualitative research methodology yielded substantially rich information regarding burn injuries

    Handley, Holly A. H.; Houston, Nancy P.

    2010-01-01

    The NATO Human View is a system architectural viewpoint that focuses on the human as part of a system. Its purpose is to capture the human requirements and to inform on how the human impacts the system design. The viewpoint contains seven static models that include different aspects of the human element, such as roles, tasks, constraints, training and metrics. It also includes a Human Dynamics component to perform simulations of the human system under design. One of the static models, termed Human Networks, focuses on the human-to-human communication patterns that occur as a result of ad hoc or deliberate team formation, especially teams distributed across space and time. Parameters of human teams that effect system performance can be captured in this model. Human centered aspects of networks, such as differences in operational tempo (sense of urgency), priorities (common goal), and team history (knowledge of the other team members), can be incorporated. The information captured in the Human Network static model can then be included in the Human Dynamics component so that the impact of distributed teams is represented in the simulation. As the NATO militaries transform to a more networked force, the Human View architecture is an important tool that can be used to make recommendations on the proper mix of technological innovations and human interactions.

    2018-03-06

    Two new methods to estimate the asymptotic covariance matrix for marginal maximum likelihood estimation of cognitive diagnosis models (CDMs), the inverse of the observed information matrix and the sandwich-type estimator, are introduced. Unlike several previous covariance matrix estimators, the new methods take into account both the item and structural parameters. The relationships between the observed information matrix, the empirical cross-product information matrix, the sandwich-type covariance matrix and the two approaches proposed by de la Torre (2009, J. Educ. Behav. Stat., 34, 115) are discussed. Simulation results show that, for a correctly specified CDM and Q-matrix or with a slightly misspecified probability model, the observed information matrix and the sandwich-type covariance matrix exhibit good performance with respect to providing consistent standard errors of item parameter estimates. However, with substantial model misspecification only the sandwich-type covariance matrix exhibits robust performance. © 2018 The British Psychological Society.

    In this NATO-sponsored Advanced Research Workshop we succeeded in bringing together approximately forty scientists working in the three main areas of structurally incommensurate materials: incommensurate crystals (primarily ferroelectric insulators), incommensurate liquid crystals, and metallic quasi-crystals. Although these three classes of materials are quite distinct, the commonality of the physics of the origin and descrip­ tion of these incommensurate structures is striking and evident in these proceedings. A measure of the success of this conference was the degree to which interaction among the three subgroups occurred; this was facili­ tated by approximately equal amounts of theory and experiment in the papers presented. We thank the University of Colorado for providing pleasant housing and conference facilities at a modest cost, and we are especially grate­ ful to Ann Underwood, who retyped all the manuscripts into camera-ready form.

    This publication is the Proceedings of the NATO Advanced Research Workshop (ARW) on the Dynamics of Polyatomic Van der Waals Molecules held at the Chateau de Bonas, Castera-Verduzan, France, from August 21 through August 26, 1989. Van der Waals complexes provide important model problems for understanding energy transfer and dissipation. These processes can be described in great detail for Van der Waals complexes, and the insight gained from such studies can be applied to more complicated chemical problems that are not amenable to detailed study. The workshop concentrated on the current questions and future prospects for extend­ ing our highly detailed knowledge of triatomic Van der Waals molecule dynamics to polyatomic molecules and clusters (one molecule surrounded by several, or up to sev­ eral tens of, atoms). Both experimental and theoretical studies were discussed, with particular emphasis on the dynamical behavior of dissociation as observed in the dis­ tributions of quantum states of the dissociatio...

    Systems of computer codes, so-called 'integral' codes, are being developed to simulate the scenario of a hypothetical severe accident in a light water reactor, from the initial event until the possible radiological release of fission products out of the containment. They couple the predominant physical phenomena that occur in the different reactor zones and simulate the actuation of safety systems by procedures and by operators. In order to allow to study a great number of scenarios, a compromise must be found between precision of results and calculation time: one day of accident time should take less than one day of real time to simulate on a PC computer. This search of compromise is a real challenge for such integral codes. The development of the ASTEC integral code was initiated jointly by IRSN and GRS as an international reference code. The latest version 1.0 of ASTEC, including the new modules CESAR and DIVA which model the behaviour of the reactor cooling system and the core degradation, is presented here. Validation of the modules and one plant application are described

    Full Text Available The article investigates the results and prospects of the NATO Summit in Warsaw in 2016 for Ukraine. It was determined that one of the Summit’s outcomes for Ukraine can be considered categorical NATO’s condemnation of aggression acts of the Russian Federation against our country, and also that will never be legitimized its actions on the change of borders, in particular the annexation of Crimea and support of separatism in Ukraine. It is proved that the approval of the Comprehensive Assistance Package for Ukraine will contribute to the reforming of the defense and security structures based on NATO’s standards and principles, including the establishment of civilian democratic control over the armed forces and to ensure their interoperability with NATO. Reasoned argument that the presentation of the Strategic Defense Bulletin of Ukraine at the Summit is a demonstration of execution of the programming steps of Ukraine’s cooperation with NATO, but at the same time, its practical component of the full implementation raises a number of doubts. It is founded that the content of the joint statement of the Commission Ukraine – NATO at the highest level is, to a greater extent, declarative than practical. It made a conclusion that the outcomes of the NATO Summit on Ukraine could be more if the Ukrainian delegation had previously worked in more detail the practical component of their positions. It was determined that an important issue for Ukraine in the future will clearly define NATO’s position with regard to the Russian Federation. On how quickly this happens will depends the further determining (or, perhaps, transformation of the course of cooperation with NATO.

    The research field focussing on the investigations and the analyses of severe accidents is an important part of the nuclear safety. To maintain the safety barriers as long as possible and to retain the radioactivity within the airtight premises or the containment, to avoid or mitigate the consequences of such events and to assess the risk, thorough studies are needed. On the one side, it is the aim of the severe accident research to understand the complex phenomena during the in- and ex-vessel phase, involving reactor-physics, thermal-hydraulics, physicochemical and mechanical processes. On the other side the investigations strive for effective severe accident management measures. This paper is focused on the possibilities for accident management measures in case of severe accidents. The reactor pressure vessel is the last barrier to keep the molten materials inside the reactor, and thus to prevent higher loads to the containment. To assess the behaviour of a nuclear power plant during transient or accident conditions, computer codes are widely used, which have to be validated against experiments or benchmarked against other codes. The analyses performed with the integral code ASTEC cover two accident sequences which could lead to a severe accident: a small break loss of coolant accident and a station blackout. The results have shown that in case of unavailability of major active safety systems the reactor pressure vessel would ultimately fail. The discussed issues concern the main phenomena during the early and late in-vessel phase of the accident, the time to core heat-up, the hydrogen production, the mass of corium in the reactor pressure vessel lower plenum and the failure of the reactor pressure vessel. Additionally, possible operator's actions and countermeasures in the preventive or mitigative domain are addressed. The presented investigations contribute to the validation of the European integral severe accidents code ASTEC for WWER-1000 type of reactors

    The SOPHAEROS module of the ASTEC V1.2.1 code was used. The results are compared to those obtained by using the MELCOR 1.8.5 code. One case was also calculated where instead of being provided by other ASTEC modules, the input data for the SOPHAEROS module are taken over from the MELCOR results. Marked differences were observed between the results of the two codes, which can be only partially explained in terms of the different assumptions made in them. The deposition profiles along the primary piping, however, are similar in the two codes

    During the past few years there has been intense research activity in the design, synthesis, and characterization of materials which are formed from molecular precursors, and which have high or metal-like electrical conductivities, i.e. dcr/dT < O. It has been widely supposed that these new materials, which are commonly called molecular metals, would be pressed into service, for example as devices. Up to now, widespread, practical applications of these sub­ stances have not developed. The NATO Advanced Research Institute on Molecular Metals at Les Arcs, France, September 10-16, 1978 was organized to discuss the scientific and technological potential of research and development in this field. The proceedings of the Institute constitute this book. Several lectures were devoted to the assessment of the present status of research on systems which serve to define major components of the field. The systems which were discussed included TTF-TCNQ, platinum chain compounds, (SN)x, polyacetylene, polydiacetylene, g...

    These proceedings are based upon introductory talks, research reports and discussions from the NATO Advanced Workshop on the "Morphology and Dynamics of the Polar Cusp", held at Lillehammer, Norway, 7-12 May, 1984. The upper atmosphere at high latitudes is called the "Earth's win­ dow to outer space". Through various electrodynamic coupling process­ es as well as through direct transfer of particles many geophysical effects displayed there are direct manifestations of phenomena occurring in the deep space. The high latitude ionosphere will also exert a feedback on the regions of the magnetosphere and atmosphere to which it is coupled, acting as a momentum and energy source and sink, and a source of particles. Of particular interest are the sections of the near space known as the Polar Cusp. A vast portion of the earth's magnetic field envelope is electrically connected to these regions. This geometry results in a spatial mapping of the magnetospheric pro­ cesses and a focusing on to the ionosphere. In the ...

    This work represents the account of a NATO Advanced Research Workshop on "Thin Film Growth Techniques for Low Dimensional Structures", held at the University of Sussex, Brighton, England from 15-19 Sept. 1986. The objective of the workshop was to review the problems of the growth and characterisation of thin semiconductor and metal layers. Recent advances in deposition techniques have made it possible to design new material which is based on ultra-thin layers and this is now posing challenges for scientists, technologists and engineers in the assessment and utilisation of such new material. Molecular beam epitaxy (MBE) has become well established as a method for growing thin single crystal layers of semiconductors. Until recently, MBE was confined to the growth of III-V compounds and alloys, but now it is being used for group IV semiconductors and II-VI compounds. Examples of such work are given in this volume. MBE has one major advantage over other crystal growth techniques in that the structure of the growi...

  18. Validation of CESAR Thermal-hydraulic Module of ASTEC V1.2 Code on BETHSY Experiments

    Science.gov (United States)

    Tregoures, Nicolas; Bandini, Giacomino; Foucher, Laurent; Fleurot, Joëlle; Meloni, Paride

    The ASTEC V1 system code is being jointly developed by the French Institut de Radioprotection et Sûreté Nucléaire (IRSN) and the German Gesellschaft für Anlagen und ReaktorSicherheit (GRS) to address severe accident sequences in a nuclear power plant. Thermal-hydraulics in primary and secondary system is addressed by the CESAR module. The aim of this paper is to present the validation of the CESAR module, from the ASTEC V1.2 version, on the basis of well instrumented and qualified integral experiments carried out in the BETHSY facility (CEA, France), which simulates a French 900 MWe PWR reactor. Three tests have been thoroughly investigated with CESAR: the loss of coolant 9.1b test (OECD ISP N° 27), the loss of feedwater 5.2e test, and the multiple steam generator tube rupture 4.3b test. In the present paper, the results of the code for the three analyzed tests are presented in comparison with the experimental data. The thermal-hydraulic behavior of the BETHSY facility during the transient phase is well reproduced by CESAR: the occurrence of major events and the time evolution of main thermal-hydraulic parameters of both primary and secondary circuits are well predicted.

    Information is one of an organization's most important assets. For this reason the development and maintenance of an integrated information system environment is one of the most important functions within a large organization. The Integrated Information Systems Evolution Environment (IISEE) project has as one of its primary goals a computerized solution to the difficulties involved in the development of integrated information systems. To develop such an environment a thorough understanding of the enterprise's information needs and requirements is of paramount importance. This document is the current release of the research performed by the Integrated Development Support Environment (IDSE) Research Team in support of the IISEE project. Research indicates that an integral part of any information system environment would be multiple modeling methods to support the management of the organization's information. Automated tool support for these methods is necessary to facilitate their use in an integrated environment. An integrated environment makes it necessary to maintain an integrated database which contains the different kinds of models developed under the various methodologies. In addition, to speed the process of development of models, a procedure or technique is needed to allow automatic translation from one methodology's representation to another while maintaining the integrity of both. The purpose for the analysis of the modeling methods included in this document is to examine these methods with the goal being to include them in an integrated development support environment. To accomplish this and to develop a method for allowing intra-methodology and inter-methodology model element reuse, a thorough understanding of multiple modeling methodologies is necessary. Currently the IDSE Research Team is investigating the family of Integrated Computer Aided Manufacturing (ICAM) DEFinition (IDEF) languages IDEF(0), IDEF(1), and IDEF(1x), as well as ENALIM, Entity

  1. How to Brand an International Organization. NATO Case Study

    Directory of Open Access Journals (Sweden)

    Gigi Mihaita

    2011-05-01

    Full Text Available Branding products and companies has always been associated with private enterprises and less, if ever, with international intergovernmental organizations. International organizations now have a long history behind them, a history often marked by contradictory events. In the last decade the international organizations developed their own public relations department in an attempt to communicate promptly and transmit the general audience their version of reality. Having this in mind we will try to briefly present in the current work the main reasons why we believe that the international organizations, NATO in particular, have started to see themselves as brand and to create a so called “commercial identity” by becoming a brand. By applying the conceptual and analytical framework used in analyzing the marketing strategies of the private companies we will try to see whether NATO is about to become a brand. Our starting point will be a 2008 statement of Jean-François Bureau, deputy general secretary responsible with NATO’s public diplomacy: “We have the green light to think about a branding policy for NATO”. Nowadays global society, perceptions tend to become more important than reality itself, and thus positive perceptions tend to become crucial. NATO has suffered an image decline in the last decade, therefore some new communication measures tend to impose themselves. The distinction between soft power and propaganda must be carefully analyzed when we speak about branding NATO. Thus we hope to bring some necessary clarifications in the area of NATO branding. Is there a brand? Is a brand going to be constructed? How does it differ from a commercial society? Does NATO need its own TV channel? Raising questions and offering a new perspective is, in the end, our primary goal, as a debate on this subject is a must that offers a new perspective in the area of theory of international organizations.

    2014-01-01

    Full Text Available The subject of the work analyzes the advantages and disadvantages of possible membership of the Republic of Serbia in NATO as an opportunity to answer the question of whether a commitment to military neutrality of the Republic of Serbia in comparison to the region is the best choice? The fact is that almost no other topic in our public causes so much disagreement among citizens, non-governmental organizations and political elite as is the relationship Serbia to NATO and possible membership in the union. However, although the frequent occurrence experience any reason to discuss the (un desirability of joining the military alliance, NATO membership is not a question of 'to be or not to be' that is often asked, but of the actual budget, strategic and security assessments maximizing the consensus at the national political level, as well as some public support in the country. The opinions about Atlantic integration are therefore opposed. The fact that Serbia has declared its military neutrality, which was voted by the Assembly of the Republic of Serbia. But the fact that we have dissonant tones in public, which are in line with the declaration of neutrality, despite Serbia introduced in Atlantic integration, ie. NATO. The aim of this paper is to present the needs and commitment of Serbia's membership in NATO, but to present what is good, and what's membership in NATO would have negative connotations for the country. Based on this, the reader to conclude that solution is more correct and what should be done.

    This paper presents current progress in the development of semantic data integration environment which is a part of the Biomedical Informatics Research Network (BIRN; http://www.nbirn.net) project. BIRN is sponsored by the National Center for Research Resources (NCRR), a component of the National Institutes of Health (NIH). A goal is the development of a cyberinfrastructure for biomedical research that supports advance data acquisition, data storage, data management, data integration, data mining, data visualization, and other computing and information processing services over the Internet. Each participating institution maintains storage of their experimental or computationally derived data. Mediator-based data integration system performs semantic integration over the databases to enable researchers to perform analyses based on larger and broader datasets than would be available from any single institution's data. This paper describes recent revision of the system architecture, implementation, and capabilities of the semantically based data integration environment for BIRN.

  8. NATO Advanced Research Workshop on The Biogeochemical Cycling of Sulfur and Nitrogen in the Remote Atmosphere

    1985-01-01

    Viewed from space, the Earth appears as a globe without a beginning or an end. Encompassing the globe is the atmosphere with its three phases-­ gaseous, liquid, and solid--moving in directions influenced by sunlight, gravity, and rotation. The chemical compositions of these phases are determined by biogeochemical cycles. Over the past hundred years, the processes governing the rates and reactions in the atmospheric biogeochemical cycles have typically been studied in regions where scientists lived. Hence, as time has gone by, the advances in our knowledge of atmospheric chemical cycles in remote areas have lagged substantially behind those for more populated areas. Not only are the data less abundant, they are also scattered. Therefore, we felt a workshop would be an excellent mechanism to assess the state­ of-knowledge of the atmospheric cycles of sulfur and nitrogen in remote areas and to make recommendations for future research. Thus, a NATO Advanced Research Workshop '~he Biogeochemical Cycling of Sulfu...

    In support of NASAs Aeronautics Research Mission, the Glenn Research Center has developed and assessed various constituents for a high temperature (2700F) SiCSiC CMC system for turbine engine applications. Combinations of highly creep-resistant SiC fibers, advanced 3D weaves, durable environmental barrier coatings (EBCs), and a 2700F-capable hybrid SiC matrix are being developed evaluated. The resulting improvements in CMC mechanical properties and durability will be summarized. The development and validation of models for predicting the effects of the environment on the durability of CMCs and EBCs and other operating-environment challenges including the effect of CMAS (calcium magnesium aluminosilicate) degradation of EBCs will be discussed. Progress toward the development of CMC joining technology for 2400F joint applications will also be reviewed.

    A NATO Advanced Research Workshop on Methods and Mechanisms for Producing Ions from Large Molecules was held at Minaki Lodge, Minaki, Ontario, Canada, from 24 to 28 June 1990. The workshop was hosted by the time-of-flight group of the Department of Physics at the University of Manitoba, and was attended by 64 invited participants from around the world. Twenty-nine invited talks were given and 19 papers were presented as posters. Of the 48 contributions, 38 are included in these proceedings. The conference was organized to study the rapidly changing field of mass spectrometry of biomolecules. Particle-induced desorption (especially with MeV particles) has been the most effective method of producing molecular ions from biomolecules. An important part of the workshop was devoted to recent developments in this field, particularly to progress in understanding the fundamentals of the desorption process. In this respect, the meeting was similar to previous conferences in Marburg, FRG (1978); Paris, F (1980); Uppsala...

  13. Assessment of ASTEC-CPA pool scrubbing models against POSEIDON-II and SGTR-ARTIST data

    International Nuclear Information System (INIS)

    Herranz, Luis E.; Fontanet, Joan

    2009-01-01

    Aerosol scrubbing in pools mitigates the potential source term in key severe accident scenarios in PWRs and BWRs. Even though models were extensively validated in the past, a thorough and systematic validation under key challenging conditions is missing. Some of those conditions are high injection velocity, high pool temperature and/or presence of submerged structures. In particular, in-code models have been neither updated nor validated based on the most recent experimental data. The POSEIDON-II and the SGTR-ARTIST projects produced sets of data under conditions of utmost interest for pool scrubbing validation: high temperature and submerged structures. This paper investigates the response of models encapsulated in the CPA module of the ASTEC code in the simulation of those experimental set-ups. The influence of key pool scrubbing variables like steam fraction, water depth, gas flow-rate and particle size has been analyzed. Additionally, comparisons to stand-alone code (i.e., SPARC90) responses have also been obtained, so that prediction-to-data deviations can be discussed and attributed to either model grounds and/or model implementation in integral accident codes. This work has demonstrated that ASTEC-CPA limitations to capture fundamental trends of aerosol pool scrubbing are substantial (although the SGTR scenarios should not be properly considered within the CPA scope) and they stem from both original models (i.e., SPARC90) and model implementation. This work has been carried out within the European SARNET project of the VI Framework Program of EURATOM. (author)

  15. Consultation and cooperation in NATO: nuclear planning, 1975-1987

    Energy Technology Data Exchange (ETDEWEB)

    Chernoff, F.B.

    1987-01-01

    This study looks at three types of explanation of international cooperation, which deal in different ways with communication and consultation. Themost-general theoretical explanation contrasts recent realist theories, like those of Waltz and Gilpin, with Keohane's functional theory of regimes. Secondly, the study looks at theories of information flow and processing (an element of consultation) within the alliance, like those of Deutsch and Steinbruner. Such theories explain governmental behavior using concepts like equilibrium of systems and feedback loop. Third, the study considers hypotheses that deal specifically with NATO and military alliances. The hypotheses relate alliance consultation processes to the cooperativeness of the cases' outcomes. Evidence is drawn from case studies of NATO decision-making. The cases include politically sensitive deployment issues, like the enhanced radiation warhead controversy in 1977-78 and the intermediate-range nuclear force deployment decision in 1979, and important, but less politically volatile arms-control decisions, including the 1975 option three proposal, the French plan for a conference on disarmament in Europe, approved in 1980, and the 1987 American zero-zero proposal on short- and intermediate-range nuclear forces in Europe.

  16. For a NATO defensive deterrent

    International Nuclear Information System (INIS)

    Smoke, R.

    1988-01-01

    This paper proposes that NATO should adopt, in a gradual and orderly fashion, a grand strategy and accompanying posture distinctly different from its present one. The strategy the author recommends has variously been termed non-provocative defence, defence-only defence, or defensive deterrence, employs the latter term here. By it the author means a militarily sound strategy relying solely on conventional weapons so long as the enemy uses only conventional weapons, and a posture that is unambiguously capable only of defence. Secure, second-strike nuclear forces would be retained for deterrence of any nuclear use by the opponent. This goal is consistent with the goal stated in Frank Barnaby's companion paper in this volume; here however the author lays the emphasis on political and politico-military rationales for a defensive deterrent. The paper begins with two brief arguments why a shift in NATO strategy is needed, advances some distinctions among the possible alternatives, and then presents some seven rationales for its recommended policy

    Full Text Available Faced with the greatest security challenges of this generation, the Nord Atlantic Alliance is currently implementing the most significant strategy for strengthening its collective defense capabilities since the end of the Cold War. While the public attention has focused on NATO’s military adaptation, the concerted efforts to strengthen the Alliance’s ability to withstand and recover from a military attack, have so far been less visible. However, this is changing. At the 2016 Alliance high level meeting in Warsaw, NATO leaders agreed on an unprecedented commitment to “increase resilience”. The 28 Allies work urgently to put this commitment into practice. But how to understand this NATO resilience?

    Full Text Available The paper presents the structural analysis of cooperation collectivity NATO and the EU, who are the guarantors of foreign security policy in the region and in the world. In this regard, it outlines the hypothetical discourse in the EU's relations with NATO, the United States, that have marked the start of the independence of each individual battle in terms of security. Standalone approach, reflecting the credibility of each individual collectivity, ultimately lead to a reduction of investment potential. It starts by considering a presentation of possible options on the reflection of the relations between the EU and NATO that the 'fine-tuning' proclaims the need for integration and pragmatic and rational manner, accepted by the political and economic realities in achieving interests. In this paper, the intention of the data on CSDP and critical analysis of relations between the EU and NATO and the presentation of the most significant agreements between the two collectives, help bridge the gap in the division of political interest and commitment of its leading members.

    2018-04-01

    Quantum Fisher information matrix (QFIM) is a cornerstone of modern quantum metrology and quantum information geometry. Apart from optimal estimation, it finds applications in description of quantum speed limits, quantum criticality, quantum phase transitions, coherence, entanglement, and irreversibility. We derive a surprisingly simple formula for this quantity, which, unlike previously known general expression, does not require diagonalization of the density matrix, and is provably at least as efficient. With a minor modification, this formula can be used to compute QFIM for any finite-dimensional density matrix. Because of its simplicity, it could also shed more light on the quantum information geometry in general.

  6. NATO Advanced Study Institute on Pollutants from Combustion Formation and Impact on Atmospheric Chemistry

    This volume is based on the lectures presented at the NATO Advanced Study Institute: (ASI) «Pollutants Formation from Combustion. Formation Mechanisms and Impact on th th Atmospheric Chemistry» held in Maratea, Italy, from 13 to 26 september 1998. Preservation of the environment is of increasing concern in individual countries but also at continental or world scales. The structure of a NATO ASI which involve lecturers and participants of different nationalities was thought as especially well suited to address environmental issues. As combustion is known to substantially contribute to the damaging of the atmosphere, it was natural to concentrate the ASI program on reviewing the currently available knowledge of the formation mechanisms of the main pollutants liberated by combustion systems. In most situations, pollutants are present as trace components and their formation and removal is strongly conditioned by the chemical reactions initiated by fuel consumption. Therefore specific lectures were aimed at defi...

    2017-01-13

    Bacteria often live in biofilms, which are microbial communities surrounded by a secreted extracellular matrix. Here, we demonstrate that hydrodynamic flow and matrix organization interact to shape competitive dynamics in Pseudomonas aeruginosa biofilms. Irrespective of initial frequency, in competition with matrix mutants, wild-type cells always increase in relative abundance in planar microfluidic devices under simple flow regimes. By contrast, in microenvironments with complex, irregular flow profiles - which are common in natural environments - wild-type matrix-producing and isogenic non-producing strains can coexist. This result stems from local obstruction of flow by wild-type matrix producers, which generates regions of near-zero shear that allow matrix mutants to locally accumulate. Our findings connect the evolutionary stability of matrix production with the hydrodynamics and spatial structure of the surrounding environment, providing a potential explanation for the variation in biofilm matrix secretion observed among bacteria in natural environments.

    Directory of Open Access Journals (Sweden)

    Vladislav V. Vorotnikov

    2014-01-01

    Full Text Available In the post-Soviet period participation in NATO was one of the major goals of euro-atlantic integration for the Baltic states. Political leaders of Estonia, Latvia and Lithuania have considered participation in the alliance as an important element of euro-atlantic solidarity which allows small - from all viewpoints - states claim decision-making over global issues. This satisfies demands of the political elites and victimized public consciousness for more security, makes it possible for elites to consider their states as bulwark against Russia. Throughout the whole decade, such reasoning has been reflected in doctrines and speeches of Baltic politicians. After joining NATO, the Baltic states became the most active supporters of a deeper integration in the military area and "open door" policy. They have continued reforming their armed forces and renovating military infrastructure. They have acquired "specialization" within NATO by establishing centers of excellence. In terms of euro-atlantic solidarity, the participation in the International Security Assistance Force in Afganistan has become the most important international project for the Baltic states. However, only Estonia managed to mount their defence expenses to the level of 2% GDP. During the „Ukranian crisis" the issue of Baltic membership in NATO acquired special importance. Confrontational rhetoric and appeals to "Russian threat" in Estonia, Latvia and Lithuania, on the one hand, make it possible for their political leaders to constantly demonstrate their importance in the eyes of Western partners and demand more activity of the alliance and, on the other hand, make ground for the political elites to consolidate the electorate, by that ensuring that the right-wing conservative forces remain in power.

    Early endometrial cancer with low-risk pathological features can be successfully treated by surgery alone. External beam radiotherapy added to surgery has been investigated in several small trials, which have mainly included women at intermediate risk of recurrence. In these trials, postoperative radiotherapy has been shown to reduce the risk of isolated local recurrence but there is no evidence that it improves recurrence-free or overall survival. We report the findings from the ASTEC and EN.5 trials, which investigated adjuvant external beam radiotherapy in women with early-stage disease and pathological features suggestive of intermediate or high risk of recurrence and death from endometrial cancer. Between July, 1996, and March, 2005, 905 (789 ASTEC, 116 EN.5) women with intermediate-risk or high-risk early-stage disease from 112 centres in seven countries (UK, Canada, Poland, Norway, New Zealand, Australia, USA) were randomly assigned after surgery to observation (453) or to external beam radiotherapy (452). A target dose of 40-46 Gy in 20-25 daily fractions to the pelvis, treating five times a week, was specified. Primary outcome measure was overall survival, and all analyses were by intention to treat. These trials were registered ISRCTN 16571884 (ASTEC) and NCT 00002807 (EN.5). After a median follow-up of 58 months, 135 women (68 observation, 67 external beam radiotherapy) had died. There was no evidence that overall survival with external beam radiotherapy was better than observation, hazard ratio 1.05 (95% CI 0.75-1.48; p=0.77). 5-year overall survival was 84% in both groups. Combining data from ASTEC and EN.5 in a meta-analysis of trials confirmed that there was no benefit in terms of overall survival (hazard ratio 1.04; 95% CI 0.84-1.29) and can reliably exclude an absolute benefit of external beam radiotherapy at 5 years of more than 3%. With brachytherapy used in 53% of women in ASTEC/EN.5, the local recurrence rate in the observation group at 5 years

The course joined inorganic, organic and polymer chemists to exchange their knowledge in this field. This volume contains the main and short lectures held in Akcay. To include ADMET reactions better into the title of this volume we changed it into: Metathesis Polymerization of Olefins and Alkyne Polymerization. This volume is addressed to research scientists, but also to those who start to work in the area of olefin metathesis and al...

    Full Text Available A situation often met in the Romanian Armed Forces in recent years is the need for interconnecting two networks (domains with different levels of classification. Considering that the Romanian armed troops are involved in numerous missions with NATO partners, solutions, already implemented across the organization, are considered to be applied in domestic systems, also. This paper presents the solutions adopted by NATO in order to solve the problem of cross -domains interconnections. We present the maturity level reached by these solutions and the possibility of implementing these solutions in the Romanian Armed Forces, with or without specific adaptation to our own rules and regulations. The goal is to use a NATO already proved solution to our national classified networks.

    2012-12-01

    Full Text Available The question of the compliance of the NATO operation Unified Protector with the international law has not become a key topic of scholarly debate yet. The prevailing attitude is such that NATO intervention was in accordance with the international law. Nevertheless, the article argues that NATO in Libya exceeded the UN Security Council mandate. Unified Protector was an operation conducted in the favour of one side, in this case, the rebels. NATO military engagement in Libya very much approached providing air support to Libyan rebelling groups in order to topple the regime. Furthermore, this conclusion is also confirmed by the fact that Western countries had provided military advisors and arms as well.

    2017-05-01

    The Sensor Information Testbed COllaberative Research Environment (SITCORE) and the Automated Online Data Repository (AODR) are significant enablers of the U.S. Army Research Laboratory (ARL)'s Open Campus Initiative and together create a highly-collaborative research laboratory and testbed environment focused on sensor data and information fusion. SITCORE creates a virtual research development environment allowing collaboration from other locations, including DoD, industry, academia, and collation facilities. SITCORE combined with AODR provides end-toend algorithm development, experimentation, demonstration, and validation. The AODR enterprise allows the U.S. Army Research Laboratory (ARL), as well as other government organizations, industry, and academia to store and disseminate multiple intelligence (Multi-INT) datasets collected at field exercises and demonstrations, and to facilitate research and development (R and D), and advancement of analytical tools and algorithms supporting the Intelligence, Surveillance, and Reconnaissance (ISR) community. The AODR provides a potential central repository for standards compliant datasets to serve as the "go-to" location for lessons-learned and reference products. Many of the AODR datasets have associated ground truth and other metadata which provides a rich and robust data suite for researchers to develop, test, and refine their algorithms. Researchers download the test data to their own environments using a sophisticated web interface. The AODR allows researchers to request copies of stored datasets and for the government to process the requests and approvals in an automated fashion. Access to the AODR requires two-factor authentication in the form of a Common Access Card (CAC) or External Certificate Authority (ECA)

    Full Text Available Subject of Research. The research is dedicated to the analysis of sensitivity change patterns of the cameras based on silicon CMOS-matrixes in various ambient temperatures. This information is necessary for the correct camera application for photometric measurements in-situ. The paper deals with studies of sensitivity variations of two digital cameras with different silicon CMOS matrixes in visible and near IR regions of the spectrum at temperature change. Method. Due to practical restrictions the temperature changes were recorded in separate spectral intervals important for practical use of the cameras. The experiments were carried out with the use of a climatic chamber, providing change and keeping the temperature range from minus 40 to plus 50 °C at a pitch of 10 о С. Two cameras were chosen for research: VAC-135-IP with OmniVision OV9121 matrix and VAC-248-IP with OnSemiconductor VITA2000 matrix. The two tested devices were placed in a climatic chamber at the same time and illuminated by one radiation source with a color temperature about 3000 K in order to eliminate a number of methodological errors. Main Results. The temperature dependence of the signals was shown to be linear and the matrixes sensitivities were determined. The results obtained are consistent with theoretical views, in general. The coefficients of thermal sensitivity were computed by these dependencies. It is shown that the greatest affect of temperature on the sensitivity occurs in the area (0.7–1.1 mkm. Temperature coefficients of sensitivity increase with the downward radiation wavelength increase. The experiments carried out have shown that it is necessary to take into account the changes in temperature sensitivity of silicon matrixes in the red and near in IR regions of the spectrum. The effect reveals itself in a clearly negative way in cameras with an amplitude resolution of 10-12 bits used for aerospace and space spectrozonal photography. Practical Relevance

    1989-01-01

    This book contains all the papers presented at the NATO workshop on "Optical Switching in Low Dimensional Systems" held in Marbella, Spain from October 6th to 8th, 1988. Optical switching is a basic function for optical data processing, which is of technological interest because of its potential parallelism and its potential speed. Semiconductors which exhibit resonance enhanced optical nonlinearities in the frequency range close to the band edge are the most intensively studied materials for optical bistability and fast gate operation. Modern crystal growth techniques, particularly molecular beam epitaxy, allow the manufacture of semiconductor microstructures such as quantum wells, quantum wires and quantum dots in which the electrons are only free to move in two, one or zero dimensions, of the optically excited electron-hole pairs in these low respectively. The spatial confinement dimensional structures gives rise to an enhancement of the excitonic nonlinearities. Furthermore, the variations of the microstr...

    Highlights: → The SARNET network gathers most worldwide actors involved in severe accident research. → It defines common research programmes for resolving the most important pending safety issues. → It optimises the use of the available European resources and constitutes sustainable research groups. → It disseminates the knowledge on severe accidents through education courses. → Knowledge produced is capitalized through physical models in the ASTEC simulation code. - Abstract: In order to optimise the use of the available means and to constitute sustainable research groups in the European Union, the Severe Accident Research NETwork of Excellence (SARNET) has gathered, between 2004 and 2008, 51 organizations representing most of the actors involved in severe accident (SA) research in Europe plus Canada. This project was co-funded by the European Commission (EC) under the 6th Euratom Framework Programme. Its objective was to resolve the most important pending issues for enhancing, in regard of SA, the safety of existing and future nuclear power plants (NPPs). SARNET tackled the fragmentation that existed between the national R and D programmes, in defining common research programmes and developing common computer codes and methodologies for safety assessment. The Joint Programme of Activities consisted in: -Implementing an advanced communication tool for accessing all project information, fostering exchange of information, and managing documents; - Harmonizing and re-orienting the research programmes, and defining new ones; -Analyzing the experimental results provided by research programmes in order to elaborate a common understanding of relevant phenomena; -Developing the ASTEC code (integral computer code used to predict the NPP behaviour during a postulated SA) by capitalizing in terms of physical models the knowledge produced within SARNET; - Developing scientific databases, in which the results of research experimental programmes are stored in a common

    1999-11-01

    In order to adopt potential countermeasures to protect the population during the course of an accident in a nuclear power plant a fast prediction of the radiation exposure is necessary. The basic input value for such a dispersion calculation is the source term, which is the description of the physical and chemical behavior of the released radioactive nuclides. Based on a source term data base a pilot system has been developed to determine a relevant source term and to generate the input file for the dispersion code TAMOS of the Zentralanstalt fuer Meteorologie und Geodynamik (ZAMG). This file can be sent directly as an attachment of e-mail to the TAMOS user for further processing. The source terms for 56 European nuclear power plant units are included in the pilot version of the code ASTEC (Austrian Source Term Estimation Code). The use of the system is demonstrated in an example based on an accident in the unit TEMELIN-1. In order to calculate typical core inventories for the data bank the international computer code OBIGEN 2.1 was installed and applied. The report has been completed with a discussion on the optimal data transfer. (author)

    2009-01-01

    The increase of the connectivity in the business environment, combined with the growing dependency of information systems, has become the information security management an important governance tool. Information security has as main goal to protect the business transactions in order to work normally. In this way, It will be safeguarding the business continuity. The threats of information come from hackers' attacks, electronic frauds and spying, as well as fire, electrical energy interruption and humans fault. Information security is made by implementation of a set of controls, including of the others politics, processes, procedures, organizational structures, software and hardware, which require a continuous management and a well established structure to be able to face such challenges. This work tried to search the reasons why the organizations have difficulties to make a practice of information security management. Many of them just limit to adopt points measures, sometimes they are not consistent with their realities. The market counts on enough quantity of standards and regulations related to information security issues, for example, ISO/IEC 27002, American Sarbanes-Oxley act, Basel capital accord, regulations from regulatory agency (such as the Brazilians ones ANATEL, ANVISA and CVM). The market researches have showed that the information security implementation is concentrated on a well-defined group of organization mainly formed by large companies and from specifics sectors of economy, for example, financial and telecommunication. However, information security must be done by all organizations that use information systems to carry out their activities, independently of its size or economic area that it belongs. The situation of information security in the governmental sector of Brazil, and inside its research institutions, is considered worrying by the Brazilian Court of Accounts (TCU). This research work presents an assessment and diagnostic proposal of

    In the last five years, the study of metal hydrides has ex­ panded enormously due to the potential technological importance of this class of materials in hydrogen based energy conversion schemes. The scope of this activity has been worldwide among the industrially advanced nations. There has been a consensus among researchers in both fundamental and applied areas that a more basic understanding of the properties of metal/hydrogen syster;,s is required in order to provide a rational basis for the selection of materials for specific applications. The current worldwide need for and interest in research in metal hydrides indicated the timeliness of an Advanced Study Insti­ tute to provide an in-depth view of the field for those active in its various aspects. The inclusion of speakers from non-NATO coun­ tries provided the opportunity for cross-fertilization of ideas for future research.

    2011-05-01

    Full Text Available Abstract Background HIV prevention continues to be problematic in the UK, as it does globally. The UK Department of Health has a strategic direction with greater focus on prevention as part of its World Class Commissioning Programme. There is a need for targeted evidence-based prevention initiatives. This is an exploratory study to develop an evidence mapping tool in the form of a matrix: this will be used to identify important gaps in contemporary HIV prevention evidence relevant to the UK. It has the potential to aid prioritisation in future research. Methods Categories for prevention and risk groups were developed for HIV prevention in consultation with external experts. These were used as axes on a matrix tool to map evidence. Systematic searches for publications on HIV prevention were undertaken using electronic databases for primary and secondary research undertaken mainly in UK, USA, Canada, Australia and New Zealand, 2006-9. Each publication was screened for inclusion then coded. The risk groups and prevention areas in each paper were counted: several publications addressed multiple risk groups. The counts were exported to the matrix and clearly illustrate the concentrations and gaps of literature in HIV prevention. Results 716 systematic reviews, randomised control trials and other primary research met the inclusion criteria for HIV prevention. The matrix identified several under researched areas in HIV prevention. Conclusions This is the first categorisation system for HIV prevention and the matrix is a novel tool for evidence mapping. Some important yet under-researched areas have been identified in HIV prevention evidence: identifying the undiagnosed population; international adaptation; education; intervention combinations; transgender; sex-workers; heterosexuals and older age groups. Other research recommendations: develop the classification system further and investigate transferability of the matrix to other prevention areas

    2016-01-01

    Full Text Available Characterization of the neutron environment in the central cavity of the Sandia National Laboratories' Annular Core Research Reactor (ACRR is important in order to provide experimenters with the most accurate spectral information and maintain a high degree of fidelity in performing reactor experiments. Characterization includes both modeling and experimental efforts. Building accurate neutronic models of the ACRR and the central cavity “bucket” environments that can be used by experimenters is important in planning and designing experiments, as well as assessing the experimental results and quantifying uncertainties. Neutron fluence characterizations of two bucket environments, LB44 and PLG, are presented. These two environments are used frequently and represent two extremes in the neutron spectrum. The LB44 bucket is designed to remove the thermal component of the neutron spectrum and significantly attenuate the gamma-ray fluence. The PLG bucket is designed to enhance the thermal component of the neutron spectrum and attenuate the gamma-ray fluence. The neutron characterization for each bucket was performed by irradiating 20 different activation foil types, some of which were cadmium covered, resulting in 37 different reactions at the peak axial flux location in each bucket. The dosimetry results were used in the LSL-M2 spectrum adjustment code with a 640-energy group MCNP-generated trial spectrum, self-shielding correction factors, the SNLRML or IRDFF dosimetry cross-section library, trial spectrum uncertainty, and trial covariance matrix, to generate a least-squares adjusted neutron spectrum, spectrum uncertainty, and covariance matrix. Both environment character-izations are well documented and the environments are available for use by experimenters.

  20. THE BALKANS BETWEEN THE EU AND NATO: FOCUSING ON THE FORMER YUGOSLAVIA

    Full Text Available The fragmentation of Yugoslavia has wrought extensive political and social changes in the Balkans and Europe more generally. After the collapse of communism and the breakup of Yugoslavia, many Balkan countries have transformed their political system and have begun to forge new foreign and security policy. Some of them have already joined the EU and NATO, and some are about to access these organizations. But the Western Balkan states seem to be farther in the future. In regard to the former Yugoslavia, the United States, European states and international organizations, such as the EU, NATO and UN, have attempted to engage and manage this breakup on an individual and collective basis. They have greatly influenced the process of the post-conflict nation building of this region. From this viewpoint, the paper discusses the political and social transformation of the Balkans after the breakup of the Yugoslav conflict, and the role of the EU and NATO in the process of the democratization and nation building in the former Yugoslavia. Moreover, attention is paid to the features of the involvement of the EU and NATO in the former Yugoslav conflict. In the process of Yugoslav fragmentation one can see the ‘Eastern Question’ revisited and the ‘Powder keg of Europe’ once again rising to its brim.

  3. How Long Before NATO Aircraft Carrier Force Projection Capabilities Are Successfully Countered? Some effects of the fiscal crises

    Directory of Open Access Journals (Sweden)

    Lučev Josip

    2014-10-01

    Full Text Available Growth and fiscal policy conducive to economic development have been severely jeopardized in most NATO member countries since 2008. In sharp contrast, China has experienced only a relatively slower GDP growth, which it has mitigated with a fiscally expansionary outlook. Under these conditions, when can we expect the politico-military position of NATO to be challenged? This paper surveys amphibious force projection capabilities in six countries: the USA, the UK, France, Russia, India and the People's Republic of China (PRC. An assessment of the current capability for aircraft carrier building and a survey of carrier-related ambitions is undertaken to offer projections of probable aircraft carrier fleets by 2030. The three non-NATO countries are far better positioned to build aircraft carriers than the three NATO members, with China in the lead. Nevertheless, there is a high probability of the continued military dominance of the USA and NATO, but also of a military build-up focusing on the Indian Ocean.

  4. Community problem-solving framed as a distributed information use environment: bridging research and practice

    Full Text Available Introduction. This article results from a qualitative study of 1 information behavior in community problem-solving framed as a distributed information use environment and 2 approaches used by a best-practice library to anticipate information needs associated with community problem solving. Method. Several approaches to data collection were used - focus groups, interviews, observation of community and library meetings, and analysis of supporting documents. We focused first on the information behaviour of community groups. Finding that the library supported these activities we sought to understand its approach. Analysis. Data were coded thematically for both information behaviour concepts and themes germane to problem-solving activity. A grounded theory approach was taken to capture aspects of the library staff's practice. Themes evolved from the data; supporting documentation - reports, articles and library communication - was also coded. Results. The study showed 1 how information use environment components (people, setting, problems, problem resolutions combine in this distributed information use environment to determine specific information needs and uses; and 2 how the library contributed to the viability of this distributed information use environment. Conclusion. Community problem solving, here explicated as a distributed IUE, is likely to be seen in multiple communities. The library model presented demonstrates that by reshaping its information practice within the framework of an information use environment, a library can anticipate community information needs as they are generated and where they are most relevant.

  14. Search for the truth about the NATO use of depleted uranium in the war against Yugoslavia - truth under the DU carpet

    International Nuclear Information System (INIS)

    Ajdacic, V.; Jaksic, P.

    2002-01-01

    Having produced thousands atomic, hydrogen and neutron bombs USA and other members of NATO possess large amount of nuclear waste, which also includes depleted uranium. Depleted uranium is natural uranium out of which 0.5% of Uranium-235 isotope is removed to be used for atomic bombs and nuclear fuel. Produced in this way, 'depleted uranium' is still highly radioactive. In one kilogram of such uranium 25 million radioactive decays take place in one second. During the NATO war against Yugoslavia in 1999 their planes A-10 fired the shells containing 272 grams of depleted uranium as they did previously in the Gulf war with Iraq and in 1995 against the Serbs in former Bosnia and Herzegovina. The effects of this 'dirty weapon', forbidden by international conventions, have been already known as disastrous, causing not only human but ecological consequences as well. That is why depleted uranium got the name: metal of dishonor. After long denial, on May the 3 rd American General Chuck Weld has confessed that NATO aviation is using ammunition with depleted uranium in the war against Yugoslavia in Kosovo and Metohija. Number of the locations under the fire of depleted uranium after the war was rising with time. At the beginning NATO information contained small number of such 'targets', 20-30. When the soldiers of the UN peacekeeping forces at Kosovo became ill, NATO was forced to reveal the new data of the used depleted uranium. In their report from January 24, 2001 (Updated on February 8 same year) they claim that 112 locations in Kosovo and Montenegro were exposed to depleted uranium rounds fired from the guns GAU-8 of A-10 planes. According to this report one can estimate the use of about 9 tons of depleted uranium. Our careful analysis points to many mistakes, lack of data, misleading conclusions and contradictions. At least 115 locations were contaminated by depleted uranium. The minimal number of rounds could be close to 43,300, e.g. minimum 12 tons of depleted uranium

    Directory of Open Access Journals (Sweden)

    Vukadinović Lidija Čehulić

    2014-10-01

    Full Text Available Numerous representatives of theories of international relations, security theories or alliance theories have examined the new role of the North Atlantic Alliance or the North Atlantic Treaty Organization (NATO in the post-bipolar world. Parallel with the theoretical examination of goals and tasks, NATO has transformed itself in practice, following the realities of the contemporary global era. In trying to achieve and keep the primacy of the strongest military- political organization, the Alliance has - especially in the Strategic Concept adopted in Lisbon in 2010-set the normative and institutional foundations of its global engagement, fulfilling the military (hard and a wide array of non-military (soft security challenges. This strategy has given rise to "Euro-Atlanticism", as a subsystem of international relations based on strong American-European relations, to fit with the process of regionalization of global politics. However, the 2013-2014 crisis in Ukraine has turned the focus of interest and activities of NATO once again primarily to Europe and it has stressed the importance and necessity of strengthening Euro-Atlantic security and defence ties. The most powerful member of the Alliance, the United States, is again strongly engaged in Europe and Russia, as a kind of successor to the Soviet Union, is once more detected as a major threat to European security. There have been many aspects of theories of international relations that have tried to explain the dynamic of the post-Cold War international community. However, the approach based on neo-realistic assumptions of the role of a security community, collective defence and the use of military force has proved to be dominant. NATO will continue to work on its political dimension as an alliance of the democratic world and the September 2014 Wales Summit will certainly mark the return of NATO to its roots, strengthening its security and military dimensions in the collective defence of Europe

  3. Application of ASTEC, MELCOR, and MAAP Computer Codes for Thermal Hydraulic Analysis of a PWR Containment Equipped with the PCFV and PAR Systems

    Directory of Open Access Journals (Sweden)

    Siniša Šadek

    2017-01-01

    Full Text Available The integrity of the containment will be challenged during a severe accident due to pressurization caused by the accumulation of steam and other gases and possible ignition of hydrogen and carbon monoxide. Installation of a passive filtered venting system and passive autocatalytic recombiners allows control of the pressure, radioactive releases, and concentration of flammable gases. Thermal hydraulic analysis of the containment equipped with dedicated passive safety systems after a hypothetical station blackout event is performed for a two-loop pressurized water reactor NPP with three integral severe accident codes: ASTEC, MELCOR, and MAAP. MELCOR and MAAP are two major US codes for severe accident analyses, and the ASTEC code is the European code, joint property of Institut de Radioprotection et de Sûreté Nucléaire (IRSN, France and Gesellschaft für Anlagen und Reaktorsicherheit (GRS, Germany. Codes’ overall characteristics, physics models, and the analysis results are compared herein. Despite considerable differences between the codes’ modelling features, the general trends of the NPP behaviour are found to be similar, although discrepancies related to simulation of the processes in the containment cavity are also observed and discussed in the paper.

    49 organisations network in SARNET (Severe Accident Research and management NETwork) their capacities of research in order to resolve the most important remaining uncertainties and safety issues for enhancing, in regard of Severe Accidents (SA), the safety of existing and future Nuclear Power Plants (NPPs). This project has been defined bearing in mind the necessity to optimise the use of the available means and to constitute sustainable research groups. SARNET tackles the fragmentation that exists between the different R and D national programmes, notably in defining common research programmes and developing common computer tools and methodologies for safety assessment. SARNET comprises most of the actors involved in SA research in Europe. To reach these objectives, all the organizations networked in SARNET contribute to a so-called Joint Programme of Activities (JPA), which can be broken in several elements: - Implementing an advanced communication tool for fostering exchange of information; - Harmonizing and re-orienting the research programmes, and defining commonly new ones; - Analysing commonly the experimental results provided by research programmes in order to elaborate a common understanding of concerned phenomena; - Developing ASTEC code (integral computer code used to predict the NPP behaviour during a postulated SA), which capitalizes in terms of physical models the knowledge produced within SARNET; - Developing Scientific Databases, in which all the results of research programmes are stored; - Developing a common methodology for Probabilistic Safety Assessment (PSA) of NNPs; - Developing educational courses and text (source) books; - Promoting personnel mobility between the various European organisations. A few organizations are covering a wide range of competences though not complete, whereas others are specialized in very specific areas and thus complementarities are developing.

    In order to optimise the use of the available means and to constitute sustainable research groups in the European Union, the Severe Accident Research NETwork of Excellence (SARNET) has gathered 51 organisations representing most of the actors involved in Severe Accident (SA) research in Europe plus Canada. This project was co-funded by the European Commission (EC) under the 6th Euratom Framework Programme. Its objective was to resolve the most important pending issues for enhancing, in regard of SA, the safety of existing and future Nuclear Power Plants (NPPs). SARNET tackled the fragmentation that existed between the national R and D programmes, in defining common research programmes and developing common computer codes for safety assessment. The Joint Programme of Activities consisted in: (i) Implementing an advanced communication tool for accessing all project information, fostering exchange of information, and managing documents; (ii) Harmonizing and re-orienting the research programmes, and defining new ones; (iii) Analyzing the experimental results provided by research programmes in order to elaborate a common understanding of relevant phenomena; (iv) Developing the ASTEC code (integral computer code used to predict the NPP behaviour during a postulated SA) by integrating the knowledge produced within SARNET; (v) Developing Scientific Databases, in which the results of research experimental programmes are stored in a common format; (vi) Developing a common methodology for Probabilistic Safety Assessment of NPPs; (vii) Developing short courses and writing a text book on Severe Accidents for students and researchers; (viii) Promoting personnel mobility amongst various European organizations. This paper presents the major achievements after four and a half years of operation of the network, in terms of knowledge gained, of improvements of the ASTEC reference code, of dissemination of results and of integration of the research programmes conducted by the various

  13. Simulation of the containment spray system test PACOS PX2.2 with the integral code ASTEC and the containment code system COCOSYS

    International Nuclear Information System (INIS)

    Risken, Tobias; Koch, Marco K.

    2011-01-01

    The reactor safety research contains the analysis of postulated accidents in nuclear power plants (npp). These accidents may involve a loss of coolant from the nuclear plant's reactor coolant system, during which heat and pressure within the containment are increased. To handle these atmospheric conditions, containment spray systems are installed in various light water reactors (LWR) worldwide as a part of the accident management system. For the improvement and the safety ensurance in npp operation and accident management, numeric simulations of postulated accident scenarios are performed. The presented calculations regard the predictability of the containment spray system's effect with the integral code ASTEC and the containment code system COCOSYS, performed at Ruhr-Universitaet Bochum. Therefore the test PACOS Px2.2 is simulated, in which water is sprayed in the stratified containment atmosphere of the BMC (Battelle Modell-Containment). (orig.)

  14. Further analysis of the FRONT model in ASTEC by simulating the hydrogen deflagration experiment BMC Ix9

    2011-01-01

    Effects of possible hydrogen deflagration like pressure built up and temperature increase can become important for the evaluation of late phases in loss of coolant accidents. In this compact the simulation of the hydrogen deflagration test BMC Ix9 with the FRONT model of the integral lumped-parameter-code ASTEC is treated. This model is available since mid of 2009, released with ASTEC V2.0. To check the validity of the model related to the applicability on different phenomena, a large number of simulations are necessary. The model was used by RUB in the frame of the 'International Standard Problem on Hydrogen Combustion (ISP-49)' and within the EC NoE SARNET2. It has been concluded that the model is able to simulate a broad range of hydrogen deflagration phenomena under different experimental conditions. Experiments analysed in the mentioned benchmarks are characterised by flame propagation in vertical direction. Moreover there were no considerations of flame propagation in multi compartment geometries. In the BMC Ix9 test horizontal hydrogen deflagration with flame propagation in 3 rooms was investigated. The FRONT model was already validated on the BMC Hx23 experiment with sufficient results. In comparison to this test the number of compartments and the initial gas composition, like hydrogen and steam concentration differs from the BMC Ix9 experiment. Previous investigations of RUB showed that the modelling of turbulence related to the transport between different compartment and the determination of this quantity has a strong influence on the simulation results. In the following the FRONT model is described briefly, the simulation results are discussed and a first recommendation for the nodalisation is given. (orig.)

    The bombing targets of NATO forces were almost all larger towns in Serbia, and particularly the facilities of chemical and oil industry. The most severely attacked cities were Pancevo, Novi Sad, Belgrade, Nis, Kragujevac, Sombor, Krusevac, Bogutovac, Kraljevo, Smederevo, Bor, Prahovo, etc. Constantly and repeatedly attacked chemical and oil plants, in addition to direct destruction of the plants, produced divergent effects, such as emission of a variety of primary and secondary pollutants into the living environment (air, water, soil). The majority of these pollutants are documented to have not only the toxicological but also the potential carcinogenic, teratogenic and/or mutagenic effects. The activities of health service (preventive before all) included qualitative and, to a permissible extent, the quantitative measurements of the mineral oils, polychlorobiphenyls, polycyclic aromatic carbons, total carbons, phenol, 3-chloroethylene and tetrachloroethylene, benzene, toluene, xylene, ethylbenzene, styrene, phosgene, vinyl chloride monomer, 1 ,2-dichlor-oethane, dioxin, furan, toxic metals (lead, chromium, cadmium, nickel, arsenic, mercury) -first in air, then in water currents, soil, plants and animals. The peacetime networks for monitoring environmental pollution (air, water, foodstuffs) were not capable to follow up all changes that occurred during aggression. During bombing of the chemical and oil plants the health service did not register any significant increase of individuals (dwellers) presenting with accident-related signs and symptoms. The results of environmental quality obtained so far, indicate a need to follow up the subclinical and clinical manifestations of a long-term exposure of the population. However, the majority of substances that we were able to identify indicate the presence of environmental pollution which will persist for a long time in the years ahead and in concentrations which may eventually have toxicological, carcinogenic, mutagenic

    2017-01-01

    Full Text Available The integral Phébus tests were probably one of the most important experimental campaigns performed to investigate the progression of severe accidents in light water reactors. In these tests, the degradation of a PWR fuel bundle was investigated employing different control rod materials and burn-up levels in strongly or weakly oxidizing conditions. From the results of such tests, numerical codes such as ASTEC and MELCOR have been developed to describe the evolution of a severe accident. After the termination of the experimental Phébus campaign, these two codes were furthermore expanded. Therefore, the aim of the present work is to reanalyze the first Phébus test (FPT-0 employing the updated ASTEC and MELCOR versions to ensure that the new improvements introduced in such codes allow also a better prediction of these Phébus tests. The analysis focuses on the stand-alone containment aspects of this test, and the paper summarizes the main thermal-hydraulic results and presents different sensitivity analyses carried out on the aerosols and fission products behavior. This paper is part of a series of publications covering the four executed Phébus tests employing a solid PWR fuel bundle: FPT-0, FPT-1, FPT-2, and FPT-3.

  18. Burden-sharing in NATO. The Trump effect won’t last

    DEFF Research Database (Denmark)

    Jakobsen, Peter Viggo; Ringsmose, Jens

    The Trump Administration has adopted a more confrontational and transactional approach to burden-sharing in NATO. It has threatened to “moderate” its commitment to the Alliance unless the European members increase their defence spending (US Mission to NATO 2017), and contribute more to out......-of-area operations. Since President Trump entered the office, European defence spending has risen at a quicker pace, and the nature of the defence debate in Europe has changed. The Europeans are no longer debating whether they need to increase their spending; the questions discussed are how fast and how much....... Is this evidence of a “Trump effect”, and will it last? This is the question addressed in this policy brief. Because it is hard to predict the future, we adopt an historical perspective....

    During the air strikes in 1999 NATO used ammunition with depleted uranium (DU) in FRY. It is known that the DU has a long time of semi-disintegration; actually its effect is ever lasting. More than few years after the end of conflict, particles of DU dust can be detected in a soil samples as well as in some air samples. Also DU was found in the sensitive bio-materials. In this material cytogenetic and clinical laboratory investigations in persons, who lived in Southern Serbia (Vranj) and on the Kosovo have been presented. the changes have been detected in the blood cells and chromosomes. There were not found disorders in the bone marrow. The examinations included general clinical assessment blood count ratio percentage of individual leukocyte line elements, morphological changes of the blood cells in the stained capillary smears observed under microscope, leukocyte enzyme activity. Incidence of the chromosomal aberrations in our series evidence the results characteristic for individuals occupationally exposed to ionizing irradiation for the prolonged period of the time. The difference in number of aberrations and aberrant cells in the exposed and unexposed subjects is statistically significant. Future environmental investigations are needed, as well as awareness-raising for the local population and other risk groups. The contamination should be prevented by clean up of DU particles and stop its entry into the food chain. The population of the contaminated regions should be subjected to annual screenings according to the program of the targeted examination aimed at detection of internal contamination in order to enable early diagnosis and treatment of the diseases. The particular attention should be paid to children and pregnant women, due to their increased radio-sensitivity. (Author) 24 refs

  5. A National Scale Sustainable Agriculture Matrix of Indicators to Inform Policy

    Science.gov (United States)

    Davidson, E. A.; Zhang, X.

    2017-12-01

    The ratification of Sustainable Development Goals (SDGs) by all member countries of the United Nations demonstrates the determination of the international community in moving towards a sustainable future. To enable and encourage accountability, independent and transparent measurements of national sustainability efforts are essential. Among all sectors, agriculture is fundamental to all three pillars of sustainability, namely environment, society, and economy. However, the definition of a sustainable agriculture and the feasibility of measuring it remain elusive, in part because it encompasses both biophysical and socio-economic components that are still poorly integrated. Therefore, we have been developing a Sustainable Agriculture Matrix (SAM) on a national scale in order to measure country-level performance in agriculture. First proposed by Swaminathan for agricultural research and policy in 1990s, SAM is a collection of indicators measuring sustainable agriculture from environmental, social, and economic dimensions. The environmental dimension evaluates various impacts of agricultural production on the environment, such as water consumption and nutrient pollution. The economic dimension quantifies the costs and benefits for major stakeholders involved in agricultural production, including government, industry, farmers, and consumers. The social dimension considers three major aspects: 1) social welfare (e.g., hunger and poverty rate, nutritional quality, demography of rural community); 2) equity over sectors, space, and gender (e.g., access to resources/services and opportunities, distribution of income, land ownership and tenure rights); 3) systemic risk (e.g., fragility of the global agricultural production and trade system, resilience of a farm or a country to market and natural shocks). Translating the illustrative concepts into measureable indicators will not only provide an independent and transparent measurement of national performance in the

  6. Towards a European Defense Identity Compatible with NATO

    Directory of Open Access Journals (Sweden)

    Rafael Estrella

    1997-12-01

    Full Text Available The European Security and Defense Identity (ESDI is a common but not defined goal, due to disagreements among Europeans on its political content. Reasons to explain this are related to the resistance to the idea of a European defense authority, fears of German hegemony, and the conviction that Europe is uncapable of defending herselfwithout the assistance of the United States. Estrella states that, with the end of the Cold War, some arguments opposing ESDI lost weight. However, the evolution and restructuring of NATO is not the product of European initiative, but rather an element of the U.S.strategy in Europe. Moreover, while the U.S. has a global strategy, Europe has not yet defined its security interests neither globally nor regionally. The author reviews the steps undertaken by NATO and the WEU towards further collaboration and the development of a European identity. He wonders whether there is enough political will either in Europe or the U.S. to overcome archaic views on trans-atlantic relations and narrow concepts about the future of Europe.

  8. Setting research priorities by applying the combined approach matrix.

    Science.gov (United States)

    Ghaffar, Abdul

    2009-04-01

    Priority setting in health research is a dynamic process. Different organizations and institutes have been working in the field of research priority setting for many years. In 1999 the Global Forum for Health Research presented a research priority setting tool called the Combined Approach Matrix or CAM. Since its development, the CAM has been successfully applied to set research priorities for diseases, conditions and programmes at global, regional and national levels. This paper briefly explains the CAM methodology and how it could be applied in different settings, giving examples and describing challenges encountered in the process of setting research priorities and providing recommendations for further work in this field. The construct and design of the CAM is explained along with different steps needed, including planning and organization of a priority-setting exercise and how it could be applied in different settings. The application of the CAM are described by using three examples. The first concerns setting research priorities for a global programme, the second describes application at the country level and the third setting research priorities for diseases. Effective application of the CAM in different and diverse environments proves its utility as a tool for setting research priorities. Potential challenges encountered in the process of research priority setting are discussed and some recommendations for further work in this field are provided.

    The NATO Science Committee and its subsidiary Programme Panels provide support for Advanced Research Institutes (ARI) in various fields. The idea is to bring together scientists of a chosen field with the hope that they will achieve a consensus on research direc­ tions for the future, and make recommendations for the benefit of a wider scientific community. Attendance is therefore limited to those whose experience and expertise make the conclusions significant and acceptable to the wider community. Participants are selected on the basis of substantial track records in research or in the synthesis of research results to serve mankind. The proposal for a one-week ARIon Earth Observation and In­ formation Systems was initiated by the NATO Special Programme Panel on Systems Science (SPPOSS). In approving the ARI, the senior NATO Science Committee identified the subject as one of universal impor­ tance, requiring a broad perspective on the development of opera­ tional systems based on successful experimental s...

    1990-01-01

    The hardware and software configuration of a Test Matrix Sequencer, a general purpose test matrix profiler that was developed for research test facility automation at the NASA Lewis Research Center, is described. The system provides set points to controllers and contact closures to data systems during the course of a test. The Test Matrix Sequencer consists of a microprocessor controlled system which is operated from a personal computer. The software program, which is the main element of the overall system is interactive and menu driven with pop-up windows and help screens. Analog and digital input/output channels can be controlled from a personal computer using the software program. The Test Matrix Sequencer provides more efficient use of aeronautics test facilities by automating repetitive tasks that were once done manually.

  11. Critical connections: personal learning environments and information literacy

    Directory of Open Access Journals (Sweden)

    Alison Hicks

    2015-01-01

    Full Text Available Personal learning environments (PLEs and critical information literacies (CILs are two concepts that have been presented as responses to the challenges of the rich and complex information landscape. While both approaches support learners’ critical engagement with new information environments, each was developed within a different field. This paper connects and contrasts PLEs and CILs in order to explore the design of pedagogical responses to the information environment. Through a careful examination of PLE and CIL literature, the paper demonstrates that information literacy education intersects with the concepts and goals of PLEs. As such, the authors suggest that PLE scholarship informed by CIL scholarship, and vice versa, will yield a deeper understanding of modern learning contexts as well as a more holistic and responsive learner framework. The example of the research assignment will be used to demonstrate the viability of this approach. With these propositions, the authors invite educators, librarians and information technologists to engage in a dialogue about these concepts and the potential for pedagogical change.

    Antczak- Barzan Anna

    2014-01-01

    Full Text Available The article is an attempt to answer the question about the state of Poland’s security after the first decade of the twenty-first century, what are its determinants, what kind of challenges Poland faces and which of them may turn into a threat and which into an opportunity, or what Polish potential is and which of its components determine its position on the international arena. It is achieved through a detailed analysis of actions undertaken by Poland in the international arena to strengthen its international position as well as the level of its security. Thus, the aim is to identify those determinants which may contribute to establishing a stronger position and which can create problems and become a formidable challenge in the context of various aspects of security, and even develop into a threat. Unfortunately, the picture which comes out of the above mentioned analysis is not optimistic and the impression is that Poland did not use the chance it was given after the accession to the NATO and the EU.

It was indeed necessary to record the considerable progress realized in the field of the propagation of singularities of Schwartz Distri­ butions which led recently to the birth of a new branch of Mathema­ tical Analysis called Microlocal Analysis. Most of this theory was mainly built to be applied to distribution solutions of linear partial differential problems. A large part of this institute still went in this direction. But, on the other hand, it was also time to explore the new trend to use microlocal analysis In non linear differential problems.

    Hysterectomy and bilateral salpingo-oophorectomy (BSO) is the standard surgery for stage I endometrial cancer. Systematic pelvic lymphadenectomy has been used to establish whether there is extra-uterine disease and as a therapeutic procedure; however, randomised trials need to be done to assess therapeutic efficacy. The ASTEC surgical trial investigated whether pelvic lymphadenectomy could improve survival of women with endometrial cancer. From 85 centres in four countries, 1408 women with histologically proven endometrial carcinoma thought preoperatively to be confined to the corpus were randomly allocated by a minimisation method to standard surgery (hysterectomy and BSO, peritoneal washings, and palpation of para-aortic nodes; n=704) or standard surgery plus lymphadenectomy (n=704). The primary outcome measure was overall survival. To control for postsurgical treatment, women with early-stage disease at intermediate or high risk of recurrence were randomised (independent of lymph-node status) into the ASTEC radiotherapy trial. Analysis was by intention to treat. This study is registered, number ISRCTN 16571884. After a median follow-up of 37 months (IQR 24-58), 191 women (88 standard surgery group, 103 lymphadenectomy group) had died, with a hazard ratio (HR) of 1.16 (95% CI 0.87-1.54; p=0.31) in favour of standard surgery and an absolute difference in 5-year overall survival of 1% (95% CI -4 to 6). 251 women died or had recurrent disease (107 standard surgery group, 144 lymphadenectomy group), with an HR of 1.35 (1.06-1.73; p=0.017) in favour of standard surgery and an absolute difference in 5-year recurrence-free survival of 6% (1-12). With adjustment for baseline characteristics and pathology details, the HR for overall survival was 1.04 (0.74-1.45; p=0.83) and for recurrence-free survival was 1.25 (0.93-1.66; p=0.14). Our results show no evidence of benefit in terms of overall or recurrence-free survival for pelvic lymphadenectomy in women with early

    2014-03-01

    Here we describe the Systematically Tabulated Outcomes Research Matrix (STORM) method to generate research questions from pre-existing databases with the aim of improving patient outcomes. STORM can be applied to a database by tabulating its variables into a matrix of independent variables (y-axis) and dependent variables (x-axis) and then applying each unique pairing of an independent and dependent variable to a patient population to generate potentially meaningful research questions. To demonstrate this methodology and establish proof-of-principle, STORM was applied on a small scale to the National Trauma Data Bank and generated at least seven clinically meaningful research questions. When coupled with rigorous clinical judgment, the STORM approach complements the traditional method of hypothesis formation and can be generalized to outcomes research using registry databases across different medical specialties.

    During NATO aggression on FR Yugoslavia various ammunition have been used, some of them for the first time. Among others, 30 mm bullets with depleted uranium (DU) penetrators have been used. Radioactivity contamination surveys have started during the war due to indications that DU is used in cruise missiles. Besides that, there were a lot of radioactivity analysis of food, drinking water etc. Some of the obtained results are presented in this paper. Depleted uranium ammunition can permanently contaminate environment and so produce effects on population. Relation of the international radiation and environmental protection standards and contamination levels are discussed as well. (author)

    Interference from the matrix sample can influence of the accurate analytical method. Accelerated Solvent Extraction and their purification methods were tried to separate the organic micropollutants respectively in marine sediment. Those matrix were as organic pollutants evaluation in marine environment. Polychlorinated Biphenyls (PCBs) and Organochlorine pesticides (OCPs) are two examples organic pollutant in environment which are carcinogenic and mutagenic. Marine sediments are important matrices of information regarding the human activities in coastal areas as well as the fate and behavior of organic pollutants, which are persistent in long-term. This research purpose to evaluate the matrice effect and the recovery from marine sediment spiking with several standar solution and deuterium of molecular target from organic pollutants in not polluted sample of sediment. Matrice samples was tested from indicate in unpolluted location. The methods were evaluated with standard calibration curve (linearity LOQ). Recovery (YE) relative, Matrice Effect (ME) relative correction with deuteriated standar were evaluated the interference the matrix. Interference effect for OCPs compounds were higher than PCBs in marine sediment.

    Full text of publication follows: The ASTEC integral code, jointly developed by IRSN and GRS since several years for evaluation of source term during a severe accident (SA) in a Light Water Reactor, will play a central role in the SARNET network of excellence of the 6. Framework Programme (FwP) of the European Commission which started in spring 2004. It should become the reference European SA integral code in the next years. The version V1.1, released in June 2004, allows to model most of the main physical phenomena (except steam explosion) near or at the state of the art. In order to allow to study a great number of scenarios, a compromise must be found between precision of results and calculation time: one day of accident time usually takes less than one day of real time to be simulated on a PC computer. Important efforts are being made on validation by covering more than 30 reference experiments, often International Standard Problems from OECD (CORA, LOFT, PACTEL, BETA, VANAM, ACE-RTF, Phebus.FPT1...). The code is also used for the detailed interpretation of all the integral Phebus.FP experiments. Eighteen European partners performed a first independent evaluation of the code capabilities in 2000-03 within the frame of the EVITA 5. FwP project on one hand by comparison to experiments and on another hand by benchmarking with MAAP4 and MELCOR integral codes on plant applications on PWR and VVER. Their main conclusions were the needs of improvement of code robustness (especially the 2 new modules CESAR and DIVA simulating respectively circuit thermal hydraulics and core degradation) and of post-processing tools. Some improvements have already been achieved in the latest version V 1.1 on these two aspects. A new module MEDICIS devoted to Molten Core Concrete Interaction (MCCI) is implemented in this version, with a tight coupling to the containment thermal hydraulics module CPA.

This NATO Advanced Study Institute sought to bridge the quite considerable gap which exist between the presentation of molecular electronic structure theory found in contemporary monographs such as, for example, McWeeny's Methods 0/ Molecular Quantum Mechanics (Academic Press, London, 1989) or Wilson's Electron correlation in moleeules (Clarendon Press, Oxford, 1984) and the realization of the sophisticated computational algorithms required for their practical application. It sought to underline the relation between the electronic structure problem and the study of nuc1ear motion. Software for performing molecular electronic structure calculations is now being applied in an increasingly wide range of fields in both the academic and the commercial sectors. Numerous applications are reported in areas as diverse as catalysi...

    This volume assembles the texts of presentations given at the NATO-sponsored Advanced Research Workshop on Quasi-Optical Transmission of High-Power Microwaves, held in Nizhny Novgorod, Russia in February 2004. The presentations bridge a wide range of technical areas, but share common tools of analysis and design. Applications of quasi-optics extend to the use of high-power microwaves—including millimeter-waves— for radar and communications (especially deep space millimeter-wave systems, space debris detection radar, and radar for the detection of small targets moving over heavy clutter); particle accelerators (especially for a future high-acceleration-gradient electron-positron collider); plasma research (especially for controlled nuclear fusion and waste decontamination); and material processing (in particular, ceramic sintering with millimeter-waves, and the coating of metal surfaces with protective dielectric films.). Scientists and engineers working in any of these areas should benefit significantly f...

  8. NATO Policies in the Baltics: Objectives and Priorities

    Directory of Open Access Journals (Sweden)

    Gribanova G. I.

    2018-05-01

    Full Text Available The authors employ geopolitical analysis to identify the core characteristics of NATO’s current policy towards the Baltic Sea region. After the demise of the Soviet Union, the region was considered as one of the safest in terms of military security. However, in the aftermath of the Ukraine crisis, the region has witnessed a growing tension in relations between NATO and the Russian Federation. A comparative analysis of NATO’s official documents on the Baltics shows that the chief pretext for increased military presence in the region is the alleged need to defend the Baltic states from the Russian threat. Special attention is paid to the attempts of Western military strategists to encourage the neutral Nordic states — Sweden and Finland — to accede to NATO. This would lead to the organisation’s northern enlargement. The current situation suggests that to ease tension in the Baltic Sea region Russia has not only to respond adequately to emerging military threats but also to launch an awareness campaign to explain its position and dispel the myth about Russia preparing to start a hybrid war against the Baltic States.

  12. CERR: A computational environment for radiotherapy research

    International Nuclear Information System (INIS)

    Deasy, Joseph O.; Blanco, Angel I.; Clark, Vanessa H.

    2003-01-01

    A software environment is described, called the computational environment for radiotherapy research (CERR, pronounced 'sir'). CERR partially addresses four broad needs in treatment planning research: (a) it provides a convenient and powerful software environment to develop and prototype treatment planning concepts, (b) it serves as a software integration environment to combine treatment planning software written in multiple languages (MATLAB, FORTRAN, C/C++, JAVA, etc.), together with treatment plan information (computed tomography scans, outlined structures, dose distributions, digital films, etc.), (c) it provides the ability to extract treatment plans from disparate planning systems using the widely available AAPM/RTOG archiving mechanism, and (d) it provides a convenient and powerful tool for sharing and reproducing treatment planning research results. The functional components currently being distributed, including source code, include: (1) an import program which converts the widely available AAPM/RTOG treatment planning format into a MATLAB cell-array data object, facilitating manipulation; (2) viewers which display axial, coronal, and sagittal computed tomography images, structure contours, digital films, and isodose lines or dose colorwash, (3) a suite of contouring tools to edit and/or create anatomical structures, (4) dose-volume and dose-surface histogram calculation and display tools, and (5) various predefined commands. CERR allows the user to retrieve any AAPM/RTOG key word information about the treatment plan archive. The code is relatively self-describing, because it relies on MATLAB structure field name definitions based on the AAPM/RTOG standard. New structure field names can be added dynamically or permanently. New components of arbitrary data type can be stored and accessed without disturbing system operation. CERR has been applied to aid research in dose-volume-outcome modeling, Monte Carlo dose calculation, and treatment planning optimization

  13. Project ATTACK and Project VISTA: Benchmark studies on the road to NATO's early TNF policy

    International Nuclear Information System (INIS)

    Garrity, P.J.

    1994-01-01

    This paper is concerned with those studies and analyses that affected early NATO nuclear policy and force structure. The discussion focuses specifically on two open-quotes benchmarkclose quotes activities. Project VISTA and Project ATTACK. These two studies were chosen less because one can document their direct impact on NATO nuclear policy and more because they capture the state of thinking about tactical nuclear weapons at a particular point of time. Project VISTA offers an especially important benchmark in this respect. Project ATTACK is a rather different kind of benchmark. It is not a pathbreaking study. It is much narrower and more technical than VISTA. It appears to have received no public attention. Project ATTACK is interesting because it seems to capture a open-quotes nuts-and-boltsclose quotes feel for how U.S. (and thereby NATO) theater nuclear policy was evolving prior to MC 48. The background and context for Project VISTA and Project ATTACK are presented and discussed

  18. NATO Advanced Study Institute on Advanced Physical Oceanographic Numerical Modelling

    CERN Document Server

    1986-01-01

    This book is a direct result of the NATO Advanced Study Institute held in Banyuls-sur-mer, France, June 1985. The Institute had the same title as this book. It was held at Laboratoire Arago. Eighty lecturers and students from almost all NATO countries attended. The purpose was to review the state of the art of physical oceanographic numerical modelling including the parameterization of physical processes. This book represents a cross-section of the lectures presented at the ASI. It covers elementary mathematical aspects through large scale practical aspects of ocean circulation calculations. It does not encompass every facet of the science of oceanographic modelling. We have, however, captured most of the essence of mesoscale and large-scale ocean modelling for blue water and shallow seas. There have been considerable advances in modelling coastal circulation which are not included. The methods section does not include important material on phase and group velocity errors, selection of grid structures, advanc...

  19. Current NATO strategy and no first use

    International Nuclear Information System (INIS)

    Lubkemeier, E.

    1988-01-01

    This paper reports that spurred by the public controversy about the implementation of the NATO dual-track decision, the Western Alliance is currently in the third phase of its strategy debate. The first phase ended in 1967 with the official adoption of the doctrine of massive retaliation whose center-piece was NATO's threat to respond to a Soviet attack in Europe by an early and if need be massive use of nuclear weapons. Soon thereafter this concept was called in question in the US. The critics pointed out that at a time where its vulnerability to Soviet nuclear strikes was growing (the so-called Sputnik shock of 1957 played a special role in this context), it was too risky for the United States to stumble into a nuclear exchange with the USSR over any outbreak of an armed East-West confrontation in Europe. They therefore propounded that the over-reliance of the West's deterrence on nuclear arms be diminished in favor of a stronger conventional deterrent. With the advent of the Kennedy administration in January 1961, this stance became official American policy and was expounded to the European members of the Alliance by then Secretary of Defence McNamara. This second phase of the strategy debate was concluded in 1967 by promulgating the current strategy of Flexible Response

  3. Using matrix organization to manage health care delivery organizations.

    Science.gov (United States)

    Allcorn, S

    1990-01-01

    Matrix organization can provide health care organization managers enhanced information processing, faster response times, and more flexibility to cope with greater organization complexity and rapidly changing operating environments. A review of the literature informed by work experience reveals that the use of matrix organization creates hard-to-manage ambiguity and balances of power in addition to providing positive benefits for health care organization managers. Solutions to matrix operating problems generally rely on the use of superior information and decision support systems and extensive staff training to develop attitudes and behavior consistent with the more collegial matrix organization culture. Further improvement in understanding the suitability of matrix organization for managing health care delivery organizations will involve appreciating the impact of partial implementation of matrix organization, temporary versus permanent uses of matrix organization, and the impact of the ambiguity created by dual lines of authority upon the exercise of power and authority.

    2007-01-01

    Radiotherapy research lacks a flexible computational research environment for Monte Carlo (MC) and patient-specific treatment planning. The purpose of this study was to develop a flexible software package on low-cost hardware with the aim of integrating new patient-specific treatment planning with MC dose calculations suitable for large-scale prospective and retrospective treatment planning studies. We designed the software package 'McGill Monte Carlo treatment planning' (MMCTP) for the research development of MC and patient-specific treatment planning. The MMCTP design consists of a graphical user interface (GUI), which runs on a simple workstation connected through standard secure-shell protocol to a cluster for lengthy MC calculations. Treatment planning information (e.g., images, structures, beam geometry properties and dose distributions) is converted into a convenient MMCTP local file storage format designated, the McGill RT format. MMCTP features include (a) DICOM R T, RTOG and CADPlan CART format imports; (b) 2D and 3D visualization views for images, structure contours, and dose distributions; (c) contouring tools; (d) DVH analysis, and dose matrix comparison tools; (e) external beam editing; (f) MC transport calculation from beam source to patient geometry for photon and electron beams. The MC input files, which are prepared from the beam geometry properties and patient information (e.g., images and structure contours), are uploaded and run on a cluster using shell commands controlled from the MMCTP GUI. The visualization, dose matrix operation and DVH tools offer extensive options for plan analysis and comparison between MC plans and plans imported from commercial treatment planning systems. The MMCTP GUI provides a flexible research platform for the development of patient-specific MC treatment planning for photon and electron external beam radiation therapy. The impact of this tool lies in the fact that it allows for systematic, platform

    The SARNET network has been set up under the aegis of the Framework Programmes (FP) of the European Commission on research. Two projects have been defined, both coordinated by IRSN (France), in the FP6 (2004-08) and FP7 (2009-13), with the following key objectives: Improving knowledge on severe accidents (SA) in order to reduce the uncertainties on the pending issues, thereby enhancing the plant safety, Coordinating research resources and expertise available in Europe, Preserving the research data and disseminating knowledge. The network members commit to contribute to a Joint Programme of Activities that can be broken into several elements: - Implementing an advanced communication tool for fostering exchange of information; - Harmonizing and re-orienting the research programmes, and defining commonly new ones; - Analysing commonly the experimental results provided by research programmes in order to elaborate a common understanding of concerned phenomena; - Developing ASTEC, which capitalizes in terms of models the knowledge produced within SARNET; - Developing Scientific Databases, in which all the results of research programmes are stored; - Developing a common methodology for Probabilistic Safety Assessment (PSA) of NNPs; - Developing educational courses and text (source) books; - Promoting personnel mobility between the various European organisations. SARNET provides an appropriate frame for achieving within a couple of years a sustainable integration of the European research capacities on SA. By capitalizing the acquired knowledge in ASTEC and in Scientific Databases, SARNET produces necessary conditions for preserving the knowledge produced by thousands of men-years and diffusing it to a large number of end-users. By fostering collaborative work on developing and validating ASTEC, SARNET makes this code as the European reference for any kind of water-cooled NPP existing in Europe. By fostering collaborative work in the domain of code development and PSA

    Full Text Available Introduction. This paper examines the business external environment scanning theory for information in the context of Greece. Method. A questionnaire was developed to explore the relationships between general and task business environment, perceived uncertainty, scanning strategy, and sources of information with respect to type of environment, size and industry.The research was based on a sample of 144 private organizations operating in North Greece. Analysis. Data collected were analysed using SPSS. The statistical procedures of chi-squared homogeneity test, ANOVA, Duncan's test of homogeneity of means, and related samples t-test were followed for testing the hypotheses developed. Results. The results show that perceived uncertainty of the general and task business external environment factors depend on the type of the environment, size of organization, and industry where the organizations operate; organizations adapt their scanning strategy to the complexity of the environment; personal sources of information seem to be more important than impersonal sources; external sources of information are equally important with internal sources; and higher levels of environmental uncertainty are associated with higher levels of scanning the various sources. Conclusion. Business external environment scanning of information is influenced by the characteristics of the organizations themselves and by the characteristics of the external environment within which the organizations operate. The study contributes to both environmental scanning theory and has important messages for practitioners.

  12. On the equilibrium state of a small system with random matrix coupling to its environment

    Science.gov (United States)

    Lebowitz, J. L.; Pastur, L.

    2015-07-01

    We consider a random matrix model of interaction between a small n-level system, S, and its environment, a N-level heat reservoir, R. The interaction between S and R is modeled by a tensor product of a fixed n× n matrix and a N× N Hermitian random matrix. We show that under certain ‘macroscopicity’ conditions on R, the reduced density matrix of the system {{ρ }S}=T{{r}R}ρ S\\cup R(eq), is given by ρ S(c)˜ exp \\{-β {{H}S}\\}, where HS is the Hamiltonian of the isolated system. This holds for all strengths of the interaction and thus gives some justification for using ρ S(c) to describe some nano-systems, like biopolymers, in equilibrium with their environment (Seifert 2012 Rep. Prog. Phys. 75 126001). Our results extend those obtained previously in (Lebowitz and Pastur 2004 J. Phys. A: Math. Gen. 37 1517-34) (Lebowitz et al 2007 Contemporary Mathematics (Providence RI: American Mathematical Society) pp 199-218) for a special two-level system.

  18. Enhancing situational awareness by means of visualization and information integration of sensor networks

    Science.gov (United States)

    Timonen, Jussi; Vankka, Jouko

    2013-05-01

    This paper presents a solution for information integration and sharing architecture, which is able to receive data simultaneously from multiple different sensor networks. Creating a Common Operational Picture (COP) object along with the base map of the building plays a key role in the research. The object is combined with desired map sources and then shared to the mobile devices worn by soldiers in the field. The sensor networks we used focus on location techniques indoors, and a simple set of symbols is created to present the information, as an addition to NATO APP6B symbols. A core element in this research is the MUSAS (Mobile Urban Situational Awareness System), a demonstration environment that implements central functionalities. Information integration of the system is handled by the Internet Connection Engine (Ice) middleware, as well as the server, which hosts COP information and maps. The entire system is closed, such that it does not need any external service, and the information transfer with the mobile devices is organized by a tactical 5 GHz WLAN solution. The demonstration environment is implemented using only commercial off-theshelf (COTS) products. We have presented a field experiment event in which the system was able to integrate and share real time information of a blue force tracking system, received signal strength indicator (RSSI) based intrusion detection system, and a robot using simultaneous location and mapping technology (SLAM), where all the inputs were based on real activities. The event was held in a training area on urban area warfare.

    2016-10-06

    The US Department of Veterans Affairs (VA) has developed various health information technology (HIT) resources to provide accessible veteran-centered health care. Currently, the VA is undergoing a major reorganization of VA HIT to develop a fully integrated system to meet consumer needs. Although extensive system documentation exists for various VA HIT systems, a more centralized and integrated perspective with clear documentation is needed in order to support effective analysis, strategy, planning, and use. Such a tool would enable a novel view of what is currently available and support identifying and effectively capturing the consumer's vision for the future. The objective of this study was to develop the VA HIT Systems Matrix, a novel tool designed to describe the existing VA HIT system and identify consumers' vision for the future of an integrated VA HIT system. This study utilized an expert panel and veteran informant focus groups with self-administered surveys. The study employed participatory research methods to define the current system and understand how stakeholders and veterans envision the future of VA HIT and interface design (eg, look, feel, and function). Directed content analysis was used to analyze focus group data. The HIT Systems Matrix was developed with input from 47 veterans, an informal caregiver, and an expert panel to provide a descriptive inventory of existing and emerging VA HIT in four worksheets: (1) access and function, (2) benefits and barriers, (3) system preferences, and (4) tasks. Within each worksheet is a two-axis inventory. The VA's existing and emerging HIT platforms (eg, My HealtheVet, Mobile Health, VetLink Kiosks, Telehealth), My HealtheVet features (eg, Blue Button, secure messaging, appointment reminders, prescription refill, vet library, spotlight, vitals tracker), and non-VA platforms (eg, phone/mobile phone, texting, non-VA mobile apps, non-VA mobile electronic devices, non-VA websites) are organized by row.

Currently, the VA is undergoing a major reorganization of VA HIT to develop a fully integrated system to meet consumer needs. Although extensive system documentation exists for various VA HIT systems, a more centralized and integrated perspective with clear documentation is needed in order to support effective analysis, strategy, planning, and use. Such a tool would enable a novel view of what is currently available and support identifying and effectively capturing the consumer’s vision for the future. Objective The objective of this study was to develop the VA HIT Systems Matrix, a novel tool designed to describe the existing VA HIT system and identify consumers’ vision for the future of an integrated VA HIT system. Methods This study utilized an expert panel and veteran informant focus groups with self-administered surveys. The study employed participatory research methods to define the current system and understand how stakeholders and veterans envision the future of VA HIT and interface design (eg, look, feel, and function). Directed content analysis was used to analyze focus group data. Results The HIT Systems Matrix was developed with input from 47 veterans, an informal caregiver, and an expert panel to provide a descriptive inventory of existing and emerging VA HIT in four worksheets: (1) access and function, (2) benefits and barriers, (3) system preferences, and (4) tasks. Within each worksheet is a two-axis inventory. The VA’s existing and emerging HIT platforms (eg, My HealtheVet, Mobile Health, VetLink Kiosks, Telehealth), My HealtheVet features (eg, Blue Button, secure messaging, appointment reminders, prescription refill, vet library, spotlight, vitals tracker), and non-VA platforms (eg, phone/mobile phone, texting, non-VA mobile apps, non-VA mobile electronic devices, non

    Several of the contributions to this volume bring forward many mutually beneficial interactions and connections between the three domains of the title. Developing them was the main purpose of the NATO ASI summerschool held in Montreal in 2003. Although some connections, for example between semigroups and automata, were known for a long time, developing them and surveying them in one volume is novel and hopefully stimulating for the future. Another aspect is the emphasis on the structural theory of automata that studies ways to contstruct big automata from small ones. The volume also has contributions on top current research or surveys in the three domains. One contribution even links clones of universal algebra with the computational complexity of computer science. Three contributions introduce the reader to research in the former East block.

    This study examines the design of previous and future trials of lymph node dissection in endometrial cancer. Data from previous trials were used to construct a decision analysis modeling the risk of lymphatic spread and the effects of treatment on patients with endometrial cancer. This model was then applied to previous trials as well as other future trial designs that might be used to address this subject. Comparing the predicted and actual results in the ASTEC trial, the model closely mimics the survival results with and without lymph node dissection for the low and high risk groups. The model suggests a survival difference of less than 2% between the experimental and control arms of the ASTEC trial under all circumstances. Sensitivity analyses reveal that these conclusions are robust. Future trial designs were also modeled with hysterectomy only, hysterectomy with radiation in intermediate risk patients, and staging with radiation only with node positive patients. Predicted outcomes for these approaches yield survival rates of 88%, 90%, and 93% in clinical stage I patients who have a risk of pelvic node involvement of approximately 7%. These estimates were 78%, 82%, and 89% in intermediate risk patients who have a risk of nodal spread of approximately 15%. This model accurately predicts the outcome of previous trials and demonstrates that even if lymph node dissection was therapeutic, these trials would have been negative due to study design. Furthermore, future trial designs that are being considered would need to be conducted in high-intermediate risk patients to detect any difference. Copyright © 2012 Elsevier Inc.

    CERN Document Server

    Bowman, Robert

    1986-01-01

    This is the second volume in the NATO ASI series dealing with the topic of hydrogen in solids. The first (V. B76, Metal Hydrides) appeared five years ago and focussed primarily on crystalline phases of hydrided metallic systems. In the intervening period, the amorphous solid state has become an area of intense research activity, encompassing both metallic and non-metallic, e.g. semiconducting, systems. At the same time the problem of storage of hydrogen, which motivated the first ASI, continues to be important. In the case of metallic systems, there were early indications that metallic glasses and disordered alloys may be more corrosion resistant, less susceptible to embrittlement by hydrogen and have a higher hydrogen mobility than ordered metals or intermetallics. All of these properties are desirable for hydrogen storage. Subsequent research has shown that thermodynamic instability is a severe problem in many amorphous metal hydrides. The present ASI has provided an appropriate forum to focus on these issu...

  19. Optimal power transaction matrix rescheduling under multilateral open access environment

    International Nuclear Information System (INIS)

    Moghaddam, M.P.; Raoofat, M.; Haghifam, M.R.

    2004-01-01

    This paper addresses a new concept for determining optimal transactions between different entities in a multilateral environment while benefits of both buyer and seller entities are taken into account with respect to the rules of the system. At the same time, constraints of the network are met, which leads to an optimal power flow problem. A modified power transaction matrix is proposed for modeling the environment. The optimization method in this paper is the continuation method, which is suited for complex situations of power system studies. This complexity will become more serious when dual interaction between financial and electrical subsystems of competitive power system are taken into account. The proposed approach is tested on a typical network with satisfactory results. (author)

    During the NATO bombing of the FR Yugoslavia from March 24 to June 10, 1999, according to NATO's data, there were 34 250 takeoffs of the 1200 aircrafts; 367 000 tonnes of kerosine were consumed; there were 400 Tomahawk cruise missiles and 130 air-to-ground missiles. It is estimated that 22 000-79 000 tonnes of explosives were dropped; in addition to 20 000 smart bombs and 5000 conventional bombs of various weight and purposes. The bombing had the characteristics of an ecological war, among other things. During the air strikes A-10 aircrafts fired shells with depleted uranium from 30 mm guns. According to NATO estimates, around 31 000 projectiles were fired (298 g of depleted uranium for each bullet, and more than 10 tonnes of uranium-238 as a contaminating agent), and according to the Yugoslav Army estimated, around 50 000 were fired. Some radiological, chemical and ethical consequences of NATO bombing in FR Yugoslavia are reviewed. (author)

    A technique for information retrieval includes parsing a corpus to identify a number of wordform instances within each document of the corpus. A weighted morpheme-by-document matrix is generated based at least in part on the number of wordform instances within each document of the corpus and based at least in part on a weighting function. The weighted morpheme-by-document matrix separately enumerates instances of stems and affixes. Additionally or alternatively, a term-by-term alignment matrix may be generated based at least in part on the number of wordform instances within each document of the corpus. At least one lower rank approximation matrix is generated by factorizing the weighted morpheme-by-document matrix and/or the term-by-term alignment matrix.

    Full text: This short presentation will cover the alliance's response to chemical, biological, radiological and nuclear (CBRN) proliferation, placing this in the context of the dangers involved in the potential use of such devices by non-state actors. It will include the political measures taken by NATO, the ongoing work with Russia, activities underway within the Euro-Atlantic Partnership Council, as well as the concrete 'deliverables' for the Prague Summit in November 2002. NATO deals with these issues both from the point of view of deployed military forces, as well as civil emergency planning measures, and the overview covers both elements. The alliance has recognized since the early 1990s that it is important to strengthen efforts against proliferation. The principal goal remains that of preventing proliferation from taking place, or, should it take place, to reverse it through diplomatic means. Hand in hand with such an approach goes the important role of ensuring an appropriate defense posture against the possible use of WMD. It is very important to maintain the flexibility and effectiveness of alliance forces despite the presence, the threat or the use of nuclear, biological and chemical weapons. In this context, the alliance draws upon a mix of means to address the challenges of proliferation, including deterrence and offensive and defensive means, and enhancing the effectiveness of arms control, disarmament and non-proliferation, as well as diplomatic and counter-proliferation measures. In the wake of 11 September, there is clearly an increased awareness of the potential use of WMD by non-state actors. As a result, NATO has adapted its work program to the evolving demands of the Committees we support. That said, there is a great deal of continuity in the work of a committee such as the senior defense group on proliferation - in terms of what it has been doing over recent years to enhance military readiness to operate in a WMD environment.

In order to further promote the information exchange, and to make web sites user-friendly, fiscal 1998 has performed structuring a thesis renewal system. As a result of structuring the thesis renewal system, researchers can use the system as using a word processor by inputting data from a terminal in their laboratories. The data can also be made into a data base nearly semi-automatically. In addition to reducing time loss, delay and input errors because of re-entry, the researchers can make the data into a database on nearly a real time basis, and can provide their own theses to any part of the world through Internet. With regard to retaining Internet security, the security software having been introduced last year was renewed.

    Fifty-one organisations network in SARNET (Severe Accident Research Network of Excellence) their research capacities in order to resolve the most important pending issues for enhancing, with regard to Severe Accidents (SA), the safety of existing and future Nuclear Power Plants (NPPs). This project. co-funded by the European Commission (EC) under the 6. Framework Programme, has been defined in order to optimise the use of the available means and to constitute sustainable research groups in the European Union. SARNET tackles the fragmentation that may exist between the different national R and D programmes, in defining common research programmes and developing common computer tools and methodologies for safety assessment. SARNET comprises most of the organisations involved in SA research in Europe, plus Canada. To reach these objectives, all the organisations networked in SARNET contributed to a joint Programme of Activities, which consisted of: Implementation of an advanced communication tool for accessing all project information, fostering exchange of information, and managing documents; Harmonization and re-orientation of the research programmes, and definition of new ones; Analysis of the experimental results provided by research programmes in order to elaborate a common understanding of relevant phenomena; Development of the ASTEC code (integral computer code used to predict the NPP behaviour during a postulated SA), which capitalizes in terms of physical models the knowledge produced within SARNET; Development of Scientific Databases in which all the results of research programmes are stored in a common format (DATANET); Development of a common methodology for Probabilistic Safety Assessment of NPPs; Development of short courses and writing a textbook on Severe Accidents for students and researchers; Promotion of personnel mobility amongst various European organisations.

    2010-06-01

    Biomedical researchers often work with massive, detailed and heterogeneous datasets. These datasets raise new challenges of information organization and management for scientific interpretation, as they demand much of the researchers' time and attention. The current study investigated the nature of the problems that researchers face when dealing with such data. Four major problems identified with existing biomedical scientific information management methods were related to data organization, data sharing, collaboration, and publications. Therefore, there is a compelling need to develop an efficient and user-friendly information management system to handle the biomedical research data. This study evaluated the implementation of an information management system, which was introduced as part of the collaborative research to increase scientific productivity in a research laboratory. Laboratory members seemed to exhibit frustration during the implementation process. However, empirical findings revealed that they gained new knowledge and completed specified tasks while working together with the new system. Hence, researchers are urged to persist and persevere when dealing with any new technology, including an information management system in a research laboratory environment.

    Information literacy has evolved with changes in lifelong learning. Can Brazilian health researchers search for and use updated scientific information? To describe researchers' information literacy based on their perceptions of their abilities to search for and use scientific information and on their interactions with libraries. Semi-structured interviews and focus group conducted with six Brazilian HIV/AIDS researchers. Analyses comprised the assessment of researchers as disseminators, their interactions with librarians, their use of information and communication technology and language. Interviewees believed they were partially qualified to use databases. They used words and phrases that indicated their knowledge of technology and terminology. They acted as disseminators for students during information searches. Researchers' abilities to interact with librarians are key skills, especially in a renewed context where libraries have, to a large extent, changed from physical spaces to digital environments. Great amounts of information have been made available, and researchers' participation in courses does not automatically translate into adequate information literacy. Librarians must help research groups, and as such, librarians' information literacy-related responsibilities in Brazil should be redefined and expanded.

    Full Text Available Future conflicts will necessitate the ability to conduct effective military operations in a contested information environment. The building and maintaining of robust situational awareness, protection of decision-making effectiveness of individuals and teams, fighting through information attacks from both in, and through, the cyberspace domain, will be essential. Increasing the knowledge of the mechanisms involved in degrading task performance and decision-making during cyber attacks will enable the development of advanced human-centered defensive techniques that aid fight-through capability. In this position paper, the development and evaluation of software that simulates real-time and persistent manipulation of the information environment is discussed. Results of the evaluation indicated that the task performance of a team of decision-makers performing collaborative tasks could be degraded through real-time manipulation of cyberspace content and operation. The paper concludes with a discussion of focus and direction for future research and development. It is suggested that the building of a deeper understanding of the perceptual and cognitive factors that are significant in the relationship between information environment manipulation and reduction in task performance is required. This understanding will aid in the defence of cyberspace attacks, will aid in fight through and mission assurance, and will aid the Information Operations community.

    1994-01-01

    The aim of this NATO Advanced Study Institute was to bring together scientists and students working in the field of laser matter interactions in order to review and stimulate developmentoffundamental science with ultra-short pulse lasers. New techniques of pulse compression and colliding-pulse mode-locking have made possible the construction of lasers with pulse lengths in the femtosecond range. Such lasers are now in operation at several research laboratories in Europe and the United States. These laser facilities present a new and exciting research direction with both pure and applied science components. In this ASI the emphasis is on fundamental processes occurring in the interaction of short laser pulses with atoms, molecules, solids, and plasmas. In the case of laser-atom (molecule) interactions, high power lasers provide the first access to extreme high-intensity conditions above 10'8 Watts/em', a new frontier for nonlinear interaction of photons with atoms and molecules.

    Gonfiotti, Bruno; Paci, Sandro

    2018-03-01

    During the last 40 years, many studies have been carried out to investigate the different phenomena occurring during a Severe Accident (SA) in a Nuclear Power Plant (NPP). Such efforts have been supported by the execution of different experimental campaigns, and the integral Phébus FP tests were probably some of the most important experiments in this field. In these tests, the degradation of a Pressurized Water Reactor (PWR) fuel bundle was investigated employing different control rod materials and burn-up levels in strongly or weakly oxidizing conditions. From the findings on these and previous tests, numerical codes such as ASTEC and MELCOR have been developed to analyze the evolution of a SA in real NPPs. After the termination of the Phébus FP campaign, these two codes have been furthermore improved to implement the more recent findings coming from different experimental campaigns. Therefore, continuous verification and validation is still necessary to check that the new improvements introduced in such codes allow also a better prediction of these Phébus tests. The aim of the present work is to re-analyze the Phébus FPT-2 test employing the updated ASTEC and MELCOR code versions. The analysis focuses on the stand-alone containment aspects of this test, and three different spatial nodalizations of the containment vessel (CV) have been developed. The paper summarizes the main thermal-hydraulic results and presents different sensitivity analyses carried out on the aerosols and fission products (FP) behavior. When possible, a comparison among the results obtained during this work and by different authors in previous work is also performed. This paper is part of a series of publications covering the four Phébus FP tests using a PWR fuel bundle: FPT-0, FPT-1, FPT-2, and FPT-3, excluding the FPT-4 one, related to the study of the release of low-volatility FP and transuranic elements from a debris bed and a pool of melted fuel.

    The NATO litter serves as a transport device and hospital bed during all types of operations. Little is known about the skin interface pressure on this litter. The purpose of this study was to determine whether various types of padding on the litter and body position affect the peak skin interface pressure and the total body area exposed to interface pressures above 30 mm Hg at different body areas. Thirty-two subjects participated. A repeated measures design was used. The surface effect was statistically significant for all peak pressure and surface area analyses (repeated-measures analysis of variance, p patients if feasible. Preventive measures (turning, elevating the heels) are still required.

    2005-01-01

    The aim of the work is by various nodalization schemes of the model to investigate the ASTEC v1.0 computer code sensitivity and to validate the code against PHEBUS - FPT2 experiment. This code is used for severe accident analysis. The aim corresponds to the main technical objective of the experiment which is to contribute to the validation of models and computer codes to be used for the calculation of the source term in case of a severe accident in a Light Water Reactor. The objective's scope of the FPT2 is large - separately for the bundle, the experimental circuit and the containment. Additional objectives are to characterize aerosol sizing and deposition processes, and also potential FP poisoning effects on hydrogen recombiner coupons exposed to containment atmospheric conditions representative of a LWR severe accident. The analyses of the results of the performed calculations show a good accordance with the reference case calculations, and then with the experimental data. Some differences in the calculations for the thermal behavior appear locally during the oxidation phase and the heat-up phase. There is very good confirmation regarding the volatile and semi-volatile fission products release from the fuel pellets. Important for analysis of the process is the final axial distribution of the mass of fuel relocation obtained at the end of the calculation

    Sangho Park

    2018-04-01

    Full Text Available Recently, the work environments of organizations have been in the process of transitioning into smart work environments by applying cloud computing technology in the existing work environment. The smart work environment has the characteristic of being able to access information assets inside the company from outside the company through cloud computing technology, share information without restrictions on location by using mobile terminals, and provide a work environment where work can be conducted effectively in various locations and mobile environments. Thus, in the cloud computing-based smart work environment, changes are occurring in terms of security risks, such as an increase in the leakage risk of an organization’s information assets through mobile terminals which have a high risk of loss and theft and increase the hacking risk of wireless networks in mobile environments. According to these changes in security risk, the reactive digital forensic method, which investigates digital evidence after the occurrence of security incidents, appears to have a limit which has led to a rise in the necessity of proactive digital forensic approaches wherein security incidents can be addressed preemptively. Accordingly, in this research, we design a digital forensic readiness model at the level of preemptive prevention by considering changes in the cloud computing-based smart work environment. Firstly, we investigate previous research related to the cloud computing-based smart work environment and digital forensic readiness and analyze a total of 50 components of digital forensic readiness. In addition, through the analysis of the corresponding preceding research, we design seven detailed areas, namely, outside the organization environment, within the organization guideline, system information, terminal information, user information, usage information, and additional function. Then, we design a draft of the digital forensic readiness model in the cloud

    2008-01-01

    Physical laws are for the most part expressed in terms of differential equations, and natural classes of these are in the form of conservation laws or of problems of the calculus of variations for an action functional. These problems can generally be posed as Hamiltonian systems, whether dynamical systems on finite dimensional phase space as in classical mechanics, or partial differential equations (PDE) which are naturally of infinitely many degrees of freedom. This volume is the collected and extended notes from the lectures on Hamiltonian dynamical systems and their applications that were given at the NATO Advanced Study Institute in Montreal in 2007. Many aspects of the modern theory of the subject were covered at this event, including low dimensional problems as well as the theory of Hamiltonian systems in infinite dimensional phase space; these are described in depth in this volume. Applications are also presented to several important areas of research, including problems in classical mechanics, continu...

    1999-12-01

    Full Text Available Internet provides a convenient environment to share geographic information. Web GIS (Geographic Information System even provides users a direct access environment to geographic databases through Internet. However, the complexity of geographic data makes it difficult for users to understand the real content and the limitation of geographic information. In some cases, users may misuse the geographic data and make wrong decisions. Meanwhile, geographic data are distributed across various government agencies, academic institutes, and private organizations, which make it even more difficult for users to fully understand the content of these complex data. To overcome these difficulties, this research uses metadata as a guiding mechanism for users to fully understand the content and the limitation of geographic data. We introduce three metadata standards commonly used for geographic data and metadata authoring tools available in the US. We also review the current development of geographic metadata standard in Taiwan. Two metadata authoring tools are developed in this research, which will enable users to build their own geographic metadata easily.[Article content in Chinese

    1990-01-01

    This book collects the lectures given at the NATO Advanced Study Institute on "Atoms in Strong Fields", which took place on the island of Kos, Greece, during the two weeks of October 9-21,1988. The designation "strong field" applies here to an external electromagnetic field that is sufficiently strong to cause highly nonlinear alterations in atomic or molecular struc­ ture and dynamics. The specific topics treated in this volume fall into two general cater­ gories, which are those for which strong field effects can be studied in detail in terrestrial laboratories: the dynamics of excited states in static or quasi-static electric and magnetic fields; and the interaction of atoms and molecules with intense laser radiation. In both areas there exist promising opportunities for research of a fundamental nature. An electric field of even a few volts per centimeter can be very strong on the atom­ ic scale, if it acts upon a weakly bound state. The study of Rydberg states with high reso­ lution laser spectroscop...

    2015-07-01

    Full Text Available The visual matrix is a method for researching shared experience, stimulated by sensory material relevant to a research question. It is led by imagery, visualization and affect, which in the matrix take precedence over discourse. The method enables the symbolization of imaginative and emotional material, which might not otherwise be articulated and allows "unthought" dimensions of experience to emerge into consciousness in a participatory setting. We describe the process of the matrix with reference to the study "Public Art and Civic Engagement" (FROGGETT, MANLEY, ROY, PRIOR & DOHERTY, 2014 in which it was developed and tested. Subsequently, examples of its use in other contexts are provided. Both the matrix and post-matrix discussions are described, as is the interpretive process that follows. Theoretical sources are highlighted: its origins in social dreaming; the atemporal, associative nature of the thinking during and after the matrix which we describe through the Deleuzian idea of the rhizome; and the hermeneutic analysis which draws from object relations theory and the Lorenzerian tradition of scenic understanding. The matrix has been conceptualized as a "scenic rhizome" to account for its distinctive quality and hybrid origins in research practice. The scenic rhizome operates as a "third" between participants and the "objects" of contemplation. We suggest that some of the drawbacks of other group-based methods are avoided in the visual matrix—namely the tendency for inter-personal dynamics to dominate the event.

    This paper present our investigation of the effects of NATO bombing of the Jugopetrol facilities in Serbia during the Spring of 1999. Concentrations of hazardous material in air, water and soil have been measured and compared to the situation before the bombing. Only partial results are presented in this paper. High concentrations of hydrocarbons were detected in the air immediately after the bombing and the destruction of installations, due to burning and evaporation of oil derivatives. A great amount of spilled mineral oils has been detected in water and soil near the destroyed installations. We have detected a noticeable increase in pollution after the NATO bombing. In addition to above mentioned pollution, the destruction of large parts of waste treatment system within the Jugopetrol's installations caused severe environmental problems. The recovery of the destroyed installation and waste treatment systems require considerable amount of money and time, and cannot be accomplished without the help of foreign investment. (author)

    With the plethora of information, there are many aspects to contested environments such as the protection of information, network privacy, and restricted observational and entry access. In this paper, we review and contrast the perspectives of challenges and opportunities for future developments in contested environments. The ability to operate in a contested environment would aid societal operations for highly congested areas with limited bandwidth such as transportation, the lack of communication and observations after a natural disaster, or planning for situations in which freedom of movement is restricted. Different perspectives were presented, but common themes included (1) Domain: targets and sensors, (2) network: communications, control, and social networks, and (3) user: human interaction and analytics. The paper serves as a summary and organization of the panel discussion as towards future concerns for research needs in contested environments.

    The Phebus-FPT programme, initiated in 1988 by the 'Institut de Radioprotection et de Surete Nucleaire' (IRSN) and the Joint Research Centre (JRC) of the European Commission (EC), was performed in the Phebus facility operated by 'Commissariat a'Energie Atomique' (CEA). The facility represent a 900 MWe Pressurized Water Reactor (PWR) scaled down by a factor 1:5000 which objective is to study fuel degradation and the subsequent release, transport and retention of fission products, structure, control rod and fuel materials, in case of a severe accident. The Phebus-FPT programme consists of integral in-pile tests, varying the fuel burn-up and geometry, the control rod nature, the thermal hydraulic conditions in the bundle and through the experimental circuit as well as in the containment. In primary, the integral experiments should outline a detailed description of the main phenomena of core degradation, fission product release and transport as well as radionuclide interactions. Due to that it is possible to analyse the physical and chemical processes due to a severe accident. With the ascertained data, an evaluation of the accident management measures could be made as well. A secondary aim of the Phebus tests was to enable model development and evaluation of severe accident codes such like ASTEC and ATHLET-CD. (orig.)

    As modern banking increasingly relies on the internet and computer technologies to operate their businesses and market interactions, the threats and security breaches have highly increased in recent years. Insider and outsider attacks have caused global businesses lost trillions of Dollars a year. Therefore, that is a need for a proper framework to govern the information security in the banking system. The aim of this research is to propose and design an enhanced method to evaluate information security governance (ISG) implementation in banking environment. This research examines and compares the elements from the commonly used information security governance frameworks, standards and best practices. Their strength and weakness are considered in its approaches. The initial framework for governing the information security in banking system was constructed from document review. The framework was categorized into three levels which are Governance level, Managerial level, and technical level. The study further conducts an online survey for banking security professionals to get their professional judgment about the ISG most critical components and the importance for each ISG component that should be implemented in banking environment. Data from the survey was used to construct a mathematical model for ISG evaluation, component importance data used as weighting coefficient for the related component in the mathematical model. The research further develops a method for evaluating ISG implementation in banking based on the mathematical model. The proposed method was tested through real bank case study in an Indonesian local bank. The study evidently proves that the proposed method has sufficient coverage of ISG in banking environment and effectively evaluates the ISG implementation in banking environment.

    In paediatric oncology, research and treatments are often closely combined, which may compromise voluntary informed consent of parents. We identified two key scenarios in which voluntary informed consent for paediatric oncology studies is potentially compromised due to the intertwinement of research and care. The first scenario is inclusion by the treating paediatric oncologist, the second scenario concerns treatments confined to the research context. In this article we examine whether voluntary informed consent of parents for research is compromised in these two scenarios, and if so whether this is also morally problematic. For this, we employ the account of voluntary consent from Nelson and colleagues, who assert that voluntary consent requires substantial freedom from controlling influences. We argue that, in the absence of persuasion or manipulation, inclusion by the treating physician does not compromise voluntariness. However, it may function as a risk factor for controlling influence as it narrows the scope within which parents make decisions. Furthermore, physician appeal to reciprocity is not controlling as it constitutes persuasion. In addition, framing information is a form of informational manipulation and constitutes a controlling influence. In the second scenario, treatments confined to the research context qualify as controlling if the available options are restricted through manipulation of options. Although none of the influences is morally problematic in itself, a combination of influences may create morally problematic instances of involuntary informed consent. Therefore, safeguards should be implemented to establish an optimal environment for parents to provide voluntary informed consent in an integrated research-care context. © 2015 John Wiley & Sons Ltd.

    The current external environment of information work has undergone profound changes. The world competition in Military fields, the development of national economy and the applications of high-technologies put forward higher requirements to intelligence work. Under the environment of global information integration, 'eyes and ears' roles of nuclear scientific and technical information will be more highlighted. In this context, we believe that the way of nuclear sci-tech information development should be focused on comprehensive research and be based on the building of information resources and advanced information technology methods, forming an integrated service system with capabilities of rapid resources, decision support, information assurance and sustainable development. The goal of nuclear sci-tech information development should be to serve the development of nuclear power and the popularization and application of nuclear technology in the fields of national economy, to implement the strategy of 'integrated intelligence support', to ensure the formation of rapid response capability, to enhance capabilities of decision support and science and technology development guidance, to build digital information resources and to constantly promote the research on network collaboration. This paper analyzes the characteristics of nuclear sci-tech information under new competitive environment, describes the ideas and goals of its development and proposes the way to achieve these goals. In order to provide the information support and service with the characteristics of rapid response, high quality and high efficiency, the paper also puts forward that under the new environment, we should optimize the service system, extend service functions, transform service mode, speed up the transformation on intelligence work, adjust and optimize business content and structure, promote business process re-engineering, and pay equal attention to 'ensuring demands' and 'guiding the future
