  2. Determination of the stability classes in Angra dos Reis

    International Nuclear Information System (INIS)

    The applicability of the methods for the calculation of atmospheric dispersion used in Angra dos Reis, (site of Angra I - reactor) is discussed. A review is made of the main meteorological parameters indicating turbulence, as well as of the methods presently em ployed for doing dispersion estimates. The turbulence indicator measured in Angra dos Reis and their utilization in the categorization of the stability conditions are discussed. The methods of the rate of vertical temperature variation and the fluctuation of the wind direction to calculate the concentration in the air, are used. The correlations existing between these two methods and their temporal and spacial variation are analysed. The analysis of one-year data allows the conclusion, that, due to the low wind velocity; in Angra dos Reis the fluctuation method is a good indicator of horizontal dispersion, but it does not allow the Knowledge of vertical stability which is better determined by the vertical gradient of temperature. Due to the local condition between the mountains and the sea, only experiments on atmospheric diffusion may indicate the better method for the calculation of local dispersion. (E.G.)

  3. Dispersion modelling studies: the 1984 experiment in Angra dos Reis

    International Nuclear Information System (INIS)

    The results of a numerical modelling of an atmospheric dispersion in Angra dos Reis (RJ, Brazil) are considered. A comparison between model results and monitored field concentrations is discussed from the point of view of its statistical as well as physical significance. Particular attention has been paid to the effects of the lack of homogeneity in the spatial scale (horizontal and vertical) and in the time scale (stationarity in the local meteorology), as they can be critical in coastal areas. Some suggestions are made about a real time modelling of the atmospheric dispersion on the considered site. (author)

  4. Persistency of atmospheric diffusion conditions in Angra dos Reis - Brazil

    International Nuclear Information System (INIS)

    Based on a 2 year observation period, the diffusion conditions at the Almirante Alvaro Alberto N.P.P. site, in Angra dos Reis, are analized with respect to persistency as a function of the wind direction, the Pasquill stability class and the time of the day. The Pasquill stability class relates to the bulk vertical temperature gradient measured between 2m and 50m in the atmosphere; the wind direction is measured at 50m height. The persistency is defined in this report as the probability that the wind direction will remain longer than a given time in a sector without change in the diffusion category by more than a certain stage. During the day the persistency is mostly affected by the sea breeze with predominance of the unstable and neutral categories. At night the stable categories dominate. The alternating sea and land breezes disturb daily the trade wind field resulting in low persistency of the diffusion conditions. (Author)

  9. Off-site emergency response plans in case of technological catastrophes: the case Angra dos Reis

    International Nuclear Information System (INIS)

    In the first part of the thesis a discussion of the technical, operational and methodological features of the current practices for emergency planning in case of a nuclear fallout. Based on this general reference is possible to evaluate the features in the natural and social environment of Angra dos Reis that probably will obstruct the application of the protective countermeasures to the public. These critical points are enhanced to permit the discussion of a methodological approach that is supposed to be suitable to the reality of Angra dos Reis. The approach was developed specifically to this region and was introduced as a part of the general emergency off-site plan to the Central Nuclear Almirante Alvaro Alberto (CNAAA). Starting from this experience will be possible to enlarge this approach in a further research, in order to study this potential hazards of other industrial plants. (author)

  10. Sm-Nd-Pu timepieces in the Angra dos Reis meteorite

    International Nuclear Information System (INIS)

    Sm-Nd systematics in pyroxene and phosphate mineral separates of Angra dos Reis have been studied. A pyroxene-phosphate internal isochron age of T2=4.55+-0.04 AE is obtained, in excellent agreement with reported Pb-Pb ages. 142Nd/144Nd ratios in pyroxene samples are systematically larger than those in phosphates by 6 parts in 105. This variation is tentatively assigned to a radiogenic contribution from extinct 146Sm. Fission xenon components in pyroxene and phosphate separates are characterized by discrete ratios of fission/spallation and evidence is presented for a third ratio in celsian. It is shown that this characteristic is due to a close association of 244Pu with the light REE. Computed ratios 244Pu/Nd are the same in pyroxene and phosphate separates, but 244Pu/238U and 244Pu/232Th ratios are not. Taking the fission xenon retention age to be 4.55 AE, an abundance ratio 244Pu/Nd=1.5x10-4 (or an atomic ratio 244Pu/150Nd=1.6x10-3) is obtained at this time and in the region of the solar system where the Angra dos Reis parent body formed. The exposure age of Angra dos Reis, as obtained by the 81Kr-83Kr method is 55.5+-1.2 m.y. Neutron capture during the 55.5-m.y. exposure to cosmic rays increased the ratio 150Sm/149Sm in Angra dos Reis by 6 parts in 104. (Auth.)

  11. The neutrino oscillation experiment in the reactor of Angra dos Reis

    International Nuclear Information System (INIS)

    The ANGRA project plans and status is presented, a new neutrino oscillation experiment in reactors, proposed to be assembled in Angra dos Reis nuclear complex. This experiment is intended to measure the angle θ13, the last of the three mixing angles in the neutrino sector even without a positive measure. This project proposes a multi-experiment with high sensitivity, able to achieve a sensitivity to detect anti-neutrinos disappearance of sin2 2θ13 = 0.006 in three years of operation, combining a high-brightness, low noise in cosmic rays and a careful control of systematic errors. It is planned to also explore the possibility of using the detection of neutrinos for the purpose of safeguards and non-proliferation of nuclear weapons.(author)

  13. Periods of high intensity rainfall and the safety of the Angra dos Reis nuclear power plant

    International Nuclear Information System (INIS)

    The high precipitation rates aggravate the consequences of hypothetical accidental releases of radioactive material from the Angra dos Reis Nuclear Power Plant (NPP), as determined by probabilistic risk assessment. A 30-year rainfall series was analysed, aiming at calculating the probability of occurring a given amount q of precipitation during a certain period of n days. The nine highest precipitation amounts have also been determined. The results show there was a rainier climate in the '50 s and '60 s than in the '70 s and '80 s. The risk of catastrophic landslide has been enhanced as an environmental impact of the construction of the Rio-Santos highway and NPP which have not yet gone through an abnormal rainfall period. It has been suggested that criteria should be established to reduce the nuclear power and shut down the reactor when the precipitation accumulates to a dangerous limit. (author)

  16. Wind directing correlation and vertical temperature gradient correlation with the wind direction amplitud variation at Angra dos Reis site

    International Nuclear Information System (INIS)

    Two studies are presented: an analysis of air flow characteristics at the Itaorna site, in Angra dos Reis by correlation of wind directions measured simultaneosly on four meteorological masts, and a tentative correlation of vertical temperature gradient with the wind fluctuation standard deviation. It's concluded that the wind directions change vertical and horizontally and the wind direction fluctuation amplitude holds no correlation with the vertical temperature gradient, and therefore it should not be used as an alternative for determination of stability categories.

    In the present work we use an Eulerian diffusion approach as the base for a micro-meteorological dispersion parametrisation for short range radioactive contamination modelling in the Angra dos Reis nuclear power plant site. The closure of the diffusion equation is implemented by means of eddy diffusivity (K-theory). The parametrizations for the eddy diffusivity co- efficient are determined from micro-meteorological parameters that were extracted from meso-scale Weather Research and Forecasting (WRF) simulations. The model is based on Taylors statistical theory together with a model for Eulerian turbulence spectra from a superposition of a buoyant and a shear contribution. We implement an interface between a LES model for the planetary boundary layer and orography related features of WRF and simulate four days, from February, the 1{sup st} to the 4{sup th} of 2010, for the environment around the nuclear power plant site at Angra dos Reis, Rio de Janeiro state, Brazil. After extraction of micro-meteorological data we determined the eddy diffusivities under the hypothesis of homogeneous turbulence. As the principal result we show the time dependence (for the time scale of a day) of the dimensionless vertical eddy diffusivity coefficients. (author)

  2. Determination of the safety zones of Angra dos Reis Nuclear Power Plant, according to the model of radion diffusion in the atmosphere

    International Nuclear Information System (INIS)

    The safety distance for Angra dos Reis Nuclear Power Plant are calculated, based on the model of the maximum credible accident for PWR power reactors and on the calculation of the dose due to hypothetical accidental release of radioactivity, using the model of radiation dispersion in the atmosphere. The safety distances for the Angra dos Reis reactors are also calculated using the model of the nine accident categories of the Rasmussen Report. The values of probability associated to each type of accident are used with the respective fractions of radiation release to the atmosphere. The soil contamination is also calculated for all the accidents considered and for several conditions of atmospheric stability, according to the model developed by Chamberlain. The program ACRA-II is used for calculation of the diffusion of radiation in the atmosphere, and the doses associated to it

  4. Station Blackout in unit 1 and analysis of the wind field in the region of Angra dos Reis

    International Nuclear Information System (INIS)

    Highlights: • Severe accident is one that exceeds the design basis (set of information that identifies the specific functions to be performed by an item from a nuclear facility or specific values chosen for controlling parameters as fundamental reference data for the project). • A Station Blackout occurs through loss of external energy and internal energy, consecutively. The external loss by event in the transmission lines. The internal loss by problems in diesel generators. • With a Station Blackout, the Plant begins to present problems at your core, due to failure in the cooling and in the residual heat removal. Without the removal of heat from the fuel rods, the temperature in the core increases abruptly and thus arises a series of events. - Abstract: Since the Fukushima accident a lot wondered on if a nuclear reactor is really safe and, specifically, if the Plants of Angra are trusted to a severe accident as occurred in Japan. The initiator event in Fukushima was a tsunami which in turn affected the external power system and then the internal power system, through failure of the diesel generators. In the case of Angra dos Reis the initiator event would be by sliding slope, the event most likely to occur, which affect the external network, common fault for all three units and later the internal network in this case, the plant most likely fault on your internal network is the unit 1, due the generators GD1 and GD2 have higher probabilities failure of departure and failure to continue to operate 2.86 × 10−2 and 2.4 × 10−3, in comparison with the generators GD3 and CD4, respectively 1.74 × 10−4 and 9.06 × 10−4. With relationship to the dispersibilidade of the pollutant in an eventual liberation for atmosphere, it is inferred by the results of the analysis of the winds of the area that the area presents low capacity dispersive

  5. Comparative analysis of three atmospheric dispersion coefficient systems at the Angra dos Reis, RJ, region

    International Nuclear Information System (INIS)

    A comparative analysis was made in this work among Pasquill-Gifford (PG) atmospheric dispersion coefficients and those determined at the Juelich and Karlsruhe sites with the purpose of suggesting which one would be the most applicable to the Angra site. Each one of the three systems was determined by different experiments, carried out over sites with diversified features. The systems of Juelich and Karlsruhe were obtained over sites with high surface roughness and from stacks (elevated releases), while the PG system was obtained over sites with a small surface roughness and from ground level releases. The results of the application of these systems at a complex site like Angra,which has a highly diversified structure encompassing sea, vegetation, predominance of light winds and stable stability classes, show that the PG system, the most used in the world, is still the best choice.

  6. Anthropogenic impact on the sedimentation in coastal regions: an example in Saco do Bracui - Ribeira Bay, Angra dos Reis, Brazil

    International Nuclear Information System (INIS)

    The Saco do Bracui, located in the littoral zone of the Brazilian southeast, receives run off from the region of Angra dos Reis. Anthropological intervention in this area has modified local morphology during the last 40 years. These modifications include an intense deforestation of mangrove regions, construction of the Bracui Boat Yard, the dredging of part of the draining basin and development of the coastal plain. Results from seismic surveys identify three different stratigraphic units separated by two reflectors as well as Holocenic paleodeltas and paleochannels of the Bracui and Gratau rivers. Results from this study and previous work indicate an age of 6800 years for the top of the superior unit. Areal photographs from the years 1964, 1965, 1978 and 1991 reveal the principal modifications occurring during the last 40 years in the area. Field observations from this study as well as bathymetric profiles based on the nautical maps of 1980 and 1944 reveal shoaling and erosion areas in the Saco do Bracui. Sedimentation rates, using lead-210 profiles, are between 0,17 - 1,90 cm/year and lead-210 inventory values are between 16-6-dpm/cm2/year. The results for sedimentation rate and inventory show a high accumulation around Bracui, Gratau and Frade mouth rivers and agree with results from the bathymetric profiles with respect to the site of erosion and shoaling in the Saco do Bracui. The results for grain size and lead-210 analyses support the idea that the Saco do Bracui is suffering shoaling processes in specific sites and erosion in others. Comparison between long term sedimentation rates obtained by seismic results and short term rates obtained by lead-210 shows an increase of the sedimentary discharge in the 1960's, when the intense anthropological intervention in the area began.

  7. Experiments on radionuclide accumulation by fishes from the Angra Dos Reis region of Brazil

    International Nuclear Information System (INIS)

    To follow the bioaccumulation and tissue distribution of 137Cs and 60Co in fish from tropical waters near the Angra nuclear power station in Brazil, juvenile grouper (Epinephelus sp.) were exposed under laboratory conditions to Angra sea water containing the two radionuclides initially added in chloride form. During the 4-month exposure period, the sea water was not changed and the fish received regular rations of non-radioactive food. Following uptake, the fish were dissected and composite tissue samples monitored for radioactivity. 137Cs concentration factors (CFs) were 3 and 5 in whole fish and muscle, respectively. The highest concentration of 137Cs was found in the muscle which accounted for 66% of the total body burden. In contrast, the highest concentration and greatest fraction (19%) of 60Co was located in the liver. Whole body and muscle CFs for 60Co, 0.2 and 0.08 respectively, were much lower than those for 137Cs. Compared with published data, only very small amounts of both radionuclides were taken up by bone in the present study. This observation and the fact that much higher 137Cs CFs have been reported in fish from field studies suggests that uptake through the food chain is the principal pathway for bioaccumulation in nature. Elution of freshly-prepared and previously-used radioactive sea water through chelating resins indicated that 60Co added in the cationic form was almost totally converted to neutral or anionic forms after four months. Additional experiments carried out with the previously-used experimental media demonstrated that the possibly ligand-bound 60Co was approximately 2.5 times more available for uptake by grouper than the cationic forms initially present. It is concluded that the uptake of 60Co by fish exposed to radioactive effluents would be a function of the different forms of 60Co present. 20 refs, 2 figs, 2 tabs

  8. Reevaluation of environmental monitoring program for radiological emergency at Almirante Alvaro Alberto Nuclear Power Plant, Angra dos Reis, Rio de Janeiro - Brazil

    International Nuclear Information System (INIS)

    In order to respond to a major radiological emergency at the Almirante Alvaro Alberto Nuclear Power Plant, located in Angra dos Reis, Rio de Janeiro, the Emergency Response Team of the Institute for Radiation Protection and Dosimetry (IRD/CNEN) established a program of environmental monitoring. The purpose of this program is to define a monitoring trend to assess the off-site radiological conditions and give support to decision making for implementing protective measures in case of a radiological accident, taking into account atmospheric diffusion, population conglomerates and their habits, water and land use, contemplating the entire Emergency Planning Zone of 15 km radius. This program has been reevaluated recently, aiming to optimize it and keep it up to date to assure adequacy of environmental surveillance data in support to a prompt response in case of an emergency situation in the nuclear power plant. It has been organized in the form of a handbook to facilitate handling by field teams. Future revisions will be necessary to incorporate additional pertinent information and keep the handbook up to date, since Angra dos Reis is a summer resort region, subject to constant changes. This paper discusses the structure of the environmental monitoring program and describes the content and preparation of this handbook. (author)

  9. Modelling of radionuclides dispersion in coastal waters. A study case on the dispersion of radionuclides released with the liquid effluents of Angra dos Reis NPP - Brazil

    International Nuclear Information System (INIS)

    The problem of the dispersion of radionuclides at coastal areas is discussed. The study focused on the dispersion of 3H and 137Cs released at Ribeira Bay, Rio de Janeiro, Brazil, with the liquid effluents of the Angra dos Reis nuclear power plant. It has been demonstrated that due to the site specific hydrodynamics the exportation of radionuclides to the open ocean would be a rather fast process. The study also examined the best strategy for accidental releases. It could be evaluated that in terms of the radionuclide inventory in the boxes the release at Itaorna Inlet would be a better option than the release at Piraquara de Fora Inlet. However, this option should be examined after a detailed dose assessment study. (author)

    International Nuclear Information System (INIS)

    Concentrations of Cu, Cr, Cd, Zn, Mn, Co, Pb and Ni were determined in benthic algae of Bay of Ribeira, Angra dos Reis, SE Brazilian coast. The results showed that these elements are concentrate under different degrees depending on the algae species considered: Galaxaura marginata and Caulerpa racemosa presented the highest concentrations (ppm) for Cu (5,2), Cd (1,5), Mn (91,5), Co (6,2) and Ni (8,0) and Cr (7,9) and Pb (21,9) respectively. These algae are then suggested as potential monitor species for these metals in tropical coastal waters. The estimated bioaccumulation factors varied from 102 for Ni to 105 for Pb, falling within the range reported in the literature, with the exception of Cd, which was found to be two orders of magnitude greater.

  11. Temperature distribution in the Piraquara de Fora Bay resulting from residual heat liberation of the Angra-1 Nuclear Power Plant in Angra dos Reis, RJ, Brazil and its possible ecological effects

    International Nuclear Information System (INIS)

    A preliminary evaluation was done of the potential environmental consequences derived from the emission from the condenser cooling of the nuclear power plants at the Angra dos Reis site. The calculation of the temperature field starting from the point of emission of the coolant discharge was done using the model of Stolzenbach for three dimensional heated surface discharge. Considerations were made of the potential environmental damage to the marine life based on the calculated temperature increase. Special atention was given to the potential damage to the necton's life, by estimating the probability of occurance of higher than lethal temperature for the known species living at the site. These species were given in the Safety Analysis Report of the Unity I of the nuclear station. (Author)

  15. Uptake by benthic algae of critical radionuclides to be released in the liquid effluent of the Angra dos Reis Nuclear Power Plant, R.J., Brazil

    International Nuclear Information System (INIS)

    In vitro interaction of benthic algae from the Angra dos Reis region, R.J., Brazil, was studied with critical radionuclides to be released in the liquid effluent of CNAAA (unit I). 137Cs-60Co - and 125I uptake and loss by Sargassum filipendula, Padina Vickersiae and Acanthophora Spicifera were observed. Biological half-lives and bioaccumulation factors (B.F.) were estimated. Co and I uptake were fast (apparent equilibrium in 3 to 7 days). Cs uptake was slower (2 to 3 weeks). Loss followed an inverse pattern (fast for Cs, slow for Co and I). B.F. ranged from 101 for Cs, to 103 for I and 103-104 for Co. Higher B.F. for Co and I were found for P. vickersiae (up to 1,4 X 104) an A. spicifera (up to 7 X 103) respectively. These species represent important potential media for the transference of Co-I-and-to a much lesser extent - Cs isotopes, through food-webs. They exhibited high capacity to compete with local sandy sediments for the retention of Co and I. High B.F., rapid uptake and moderate to long biological half-lives enable S. filipendula, P. vickersiae and A. specifera to be powerful aids in the monitoring of radioactive contamination by Co and I isotopes. Since the majority of marine organisms tends to exhibit Cs B.F. similars to those reported here, these algae may also be used as monitors for Cs isotopes, the low B.F. being compensated by their abundance, wide distribution and facility of collection.

  16. Levels of 137Cs and 40K in marine superficial sediments near the Angra Nuclear Power Plant (Angra dos Reis, SE Brazil)

    International Nuclear Information System (INIS)

    This study evaluated the spatial distribution of two environmentally relevant radionuclides, 137Cs and 40K, in marine superficial sediments around the Angra Nuclear Power Plant, the only Brazilian nuclear power plant complex, thus establishing a baseline for bottom sediments, given the international importance of environmental monitoring around nuclear facilities. It was observed that these radionuclides are mostly present in the muddy sediments as a result of their stronger association with its fine-grained fraction, and that their lowest levels are located around the liquid effluent discharge of the plant, as a consequence of the prevented deposition of fine sediments due to the strong discharge water flux. The comparison of the 137Cs activities in the region with other locations in the world showed that the presence of this artificial nuclide is due to the atmospheric fallout from past nuclear tests made during the Cold War, not to the nuclear power plant activities.

    Industrial accidents generally endanger structures and the set of environmental influence area where the enterprises are located, especially when affected by atmospheric dispersion of their pollutants, whose concern with the evacuation of the population is the main goal in emergency situations. Considering the nuclear complex Angra dos Reis - RJ, based on computer modeling analysis of the mechanisms of pollutant dispersion in conjunction with geographic information systems were developed. Thus, information about the dispersion of radionuclides - from simulations performed on the HYSPLIT; meteorological data (direction, intensity and calm on the wind regime and analysis of the wind field in the region using WRF), occurrence of landslides and data on the environmental study area were integrated into a GIS database using ArcGIS platform. Aiming at the identification and definition of escape routes in case of evacuation from accidental events in CNAAA, the results point solutions for long-term planning, based on weather and landslides, and short-term, supported by simulations of the dispersion radionuclides, in order to support actions that assist local emergency planning.

    Identification of families with history of cancer in the municipality of Angra dos Reis, Rio de Janeiro (Brazil), through the Brazilian Unified Primary Health Care System was explored based in the Community Health Agents (CHA) program. This study was divided into two phases: a descriptive one with a cross-sectional epidemiological data of families with history of cancer based on CHA-collected data from home visits in four primary health care units. The second phase consisted in identifying familial clustering of three or more individuals with cancer through construction of a three-generation pedigree and revisited by an itinerant group of medical geneticists. Genetic counseling was carried out with the intent of selecting potential families at risk for hereditary familial cancers. In the first phase of the study, 1,581 families were interviewed by the CHA at their homes. A positive history for cancer was present in 42.3 % of families, comprising 22.3 % with only one case per family, 11.2 % with two cases, and 8.6 % with three or more cases in the family. The informant reported that 15 % of the cases were from the father lineage, 12 % from the mother lineage, and 12.1 % within siblings. In the remaining 60.9 % families, cancer was present in both sides of the family. The types of cancer reported were uterus 8.7 % (n = 137), stomach 7.7 % (n = 122), breast 6.9 % (n = 109), throat 6.8 % (n = 99), prostate 5.4 % (n = 85), lung 5.6 % (n = 88), bowel 3.7 % (n = 59), and unspecified sites in 6.8 % (n = 108) of families. No statistical differences were noted between the data collected on each primary care unit. In the second phase of the study, 136 families (2.9 %) from the total of families interviewed in phase 1 were selected due to the presence of three or more individuals with cancer in the family. Among those, only 73 families attended genetic counseling. Comparison between the data obtained by the CHA and the medical

  1. Tritium (3H) as a tracer for monitoring the dispersion of conservative radionuclides discharged by the Angra dos Reis nuclear power plants in the Piraquara de Fora Bay, Brazil

    International Nuclear Information System (INIS)

    Presently, two nuclear power plants operate in Brazil. Both are located at Itaorna beach, Angra dos Reis, approximately 133 km from Rio de Janeiro city. The reactor cooling circuits require the input of seawater, which is later discharged through a pipeline into the adjacent Piraquara de Fora Cove. The radioactive effluents undergo ion-exchange treatment prior to their release in batches, causing the enrichment of 3H relative to other radionuclides in the discharged waters. Under steady state conditions, the 3H gradient in the Piraquara de Fora waters can be used to determine the dependence of the dilution factor on the distance from the discharge point. The present work describes experiments carried out at the reactor site during batch release episodes, including time series sampling at the discharge point and surface seawater sampling every 250 m to a distance of 1250 m, after a double distillation, the 3H concentration was measured by liquid scintillation counting applying a Quantulus liquid scintillation spectrometer. The obtained results showed a linear relationship between the 3H concentration and distance from the discharge point. At 1250 m from the discharge point a dilution index of 1:15 was measured which fits the expected value based on modeling. - Highlights: • The present work describes experiments carried out at the Angra dos Reis reactor site during batch release episodes. • Time series sampling of surface seawater were performed every 250 m to a distance of 1250 m. • It was observed a linear relationship between the 3H concentration and distance from the discharge point

    Full Text Available The main objective of this paper is to identify the variables that predict the intentions of the visitors comeback to a business fair held in Angra dos Reis, Rio de Janeiro. The evaluation was conducted through a binary logistic regression model, applied to a cross-sectional sample composed by 277 visitors. As result, it was found that, of eight hypotheses, only three were accepted. Two of them are associated to the impact of the effort and commitment perception, from the visiting public, in the prediction of the comeback intention, and the third is associated to the effect of the perceived benefits from the event to the local economy, also in the prediction of the comeback intention. Considering these results, one can conclude that the study confirms the assumptions of Grönroos (2004, which postulate that the main factors that contribute to the perceived value are associated to the minimization of the customer effort and commitment, and not only to the increasing of the benefits offered.

    International Nuclear Information System (INIS)

    This study had as purpose the assess the impact of a severe accident, and also analyze the dispersion of 131I in the atmosphere, so that, through concentrating and inhaling dose of the plume, were possible to verify if the results are in accordance with the indicated data by the Plan of Emergency of the CNAAA regarding the Impact Zone and Control. This exercise was performed with the aid of an atmospheric model and a dispersion where to atmospheric modeling we used the data coupling WRF / CALMET and of dispersion, CALPUFF. The suggested accident consists of a Station Blackout at Nuclear Power of Angra (Unit 1), where through the total core involvement, will release 100% of the 131I to the atmosphere. The value of the total activity in the nucleus to this radionuclide is 7.44 x 1017 Bq, that is relative on the sixth day of burning. This activity will be released through the chimney at a rate in Bq/s in the scenario of 12, 24, 48 and 72 hours of release. Applying the model in the proposed scenario, it is verified that the plume has concentrations of the order of 1020 Bq/m³ and dose of about 108 Sv whose value is beyond of the presented by Eletronuclear in your current emergency plan.

    International Nuclear Information System (INIS)

    The main purpose of the Environmental Monitoring Laboratory, in the Mambucaba Residential Site is to control all environment around Almirante Alvaro Alberto Nuclear Power Station (AAANPS) in order to check its operational influence on the local ecosystem. Angra I Nuclear Power Plant usually discharges liquid waste from the Treatment System (waste and recycle evaporators). Before the water is discharged into the sea, it is chemically and radiochemically and analysed to verify if dissolved contaminants are in agreement with the specifications established by the Fundacao Estadual de Engenharia de Meio Ambiente (FEEMA) for the chemical parameters and by the Comissao Nacional de Energia Nuclear (CNEN) for radiochemical parameters. Such radioactive contaminants are 58 Co, 60 Co and 54 Mn, which are activated corrosion products from structural materials of the primary system and 134 Cs and 137 Cs, fission products produced by the nuclear reactor during its operation. To measure and control the possible discharge of these radionuclides into the sea and their incorporation to the marine organisms, it was created the Environmental Radiological Monitoring Special Program (ERMSP). The purpose of this program is to control the absorption of the radionuclides 58 Co, 60 Co, 54 Mn, 134 Cs and 137 Cs in algae of the genus Sargassum located in the surroundings the discharge of the liquid effluents of the genus Sargassum located in the surroundings the discharge of the liquid effluents of the Plant in Saco de Piraquara de Fora. The algae are considered excellent bioindicators because they are fixed on the rocks, being totally dependent on the water quality where they live, being being as easy target to incorporate and to detect those radionuclides. The algae are collected bimestrally and analysed by the Laboratory. This work presents the sampling process, the preparation, the sampling process, the preparation, the analysis of the radionuclides and the results obtained. (author)

    Specific Full Scope Simulators are an essential tool for training NPP control room operators, in the formation phase as well as for maintaining their qualifications. In the last years availability of a Plant specific simulator has also become a Regulator requirement for Nuclear Power Plant operation. By providing real-time practical training for the operators, the use of a simulator allows improving the operator's performance, reducing the number of unplanned shutdowns and more effective response to abnormal and emergency operating conditions. It can also be used, among other uses, to validate procedures, test proposed plant modifications, perform engineering studies and to provide operation training for the technical support staff of the plant. The NPP site, in Angra dos Reis-RJ, Brazil, comprises the two units in operation, Unit 1, 640 MWe, Westinghouse PWR and Unit 2, 1350 MWe, KWU/Areva PWR and one unit in construction, Unit 3, 1405 MWe, KWU/Areva PWR, of the same design of Angra 2. Angra 2 has had its full scope simulator from the beginning, however this was not the case of Angra 1, that had to train its operators abroad, due to lack of a specific simulator. Eletronuclear participated in all the phases of the project, from data supply to commissioning and validation. The Angra 1 full scope simulator encompasses more than 80 systems of the plant including the Primary system, reactor core and associated auxiliary systems, the secondary system and turbo generator as well as all the Plant operational and safety I and C. The Angra 1 Main Control Room panels were reproduced in the simulator control room as well as the remote shutdown panels that are outside the control room.

  18. Radiological protection for the ANGRA 1 steam generator replacement outage

    International Nuclear Information System (INIS)

    The Angra 1 Nuclear Power Plant (NPP) is a Westinghouse two-loop plant with net output before its 1P16 Outage of 632 MWe, with the Old Steam Generators (OSG) type model D3, which were replaced by two new Steam Generators with feed water-ring system. Localized in Angra dos Reis, Rio de Janeiro - Brazil, Angra 1 started in commercial operation in 1985 and, from the beginning problems related to corrosion have appeared in the Inconel 600 alloy of the tubes. The corrosion problems indicated the necessity for a strong control of the tubes thicknesses and, after a time, the ELETRONUCLEAR decided to replace the OSG. In 2009, ELETRONUCLEAR initiated in January 24, the actions for the Steam Generators Replacement - SGR. During the SGR process, several controls were applied in field, which made possible to have no radiological accidents, no dose limits exceeded, and permitted to achieve a very good result in terms of Collective Dose. This paper describes the radiological controls applied for the Angra 1 Steam Generator Replacement Outage, the radiological protection team sizing and distribution and the obtained results. (author)

  1. Radionuclide dispersion and hydrodynamics of Ilha Grande Bay (Angra dos Reis, RJ) simulated from hypothetical accidental releases of liquid wastes

    International Nuclear Information System (INIS)

    This study has the aim to assess the impact of accidental release of radionuclides postulate from a nuclear power reactor through environmental modeling of aquatic resources. In order to do that it was used computational models of hydrodynamic circulation and transport for the simulation of tritium dispersion caused by an accidental release in Ilha Grande Bay from the site of the future third plant in two circulation scenarios. The main difference between the scenarios is based on the enhancement of dilution of the highest concentrations in the last one. This dilution enhancement resulting in decreasing concentrations was observed only during the first two weeks, when they ranged from 1 x 109 to 5 x 105 Bq/m³ close to the Itaorna beach spreading just to Sandri Island. After 180 days, the plume could not be detected anymore in the bay, because their activities would be lower than the minimum detectable value (< 11 kBq/m³). (author)

  5. Multianodic photomultiplier tube characterization at Angra Neutrinos Project

    International Nuclear Information System (INIS)

    Full text: The Angra Neutrino Project aims to perform the antineutrino flux measurement at the Angra II nuclear reactor in Angra dos Reis, and to correlate it to the nuclear fuel fission and burn-up. A veto system is essential in the detection system, because the rate of cosmic particles reaching the detector is much higher than the antineutrinos rate (signal to background ratio 105). The planned veto system for the Angra experiment is an array of the X-Y type, consisting of orthogonal scintillator plastic plates, where particles detection is provided by the coincidence of signals from two or more scintillators. The light signals are taken to a Multianodic Photomultiplier Tube (MAPMT) with 8 x 8 pixels, through wavelength shifter optical fibers. In each MAPMT pixel, light is converted to electric charge and this analog information is brought to a data acquisition system composed of preamplifiers and data processing modules (MPDs). In the MPDs the information is digitized. A control and visualization software performs data acquisition, making use of an interface to the universal serial bus (USB). In this work we present the data acquisition chain and results for the photomultiplier characterization, which involves determining the gain of each one of the pixels by two different methods: the single photoelectron spectrum, and the statistical technique. In the latter method, by varying the number of photons hitting a given pixel one may determine the gain from a relationship between the average converted charge and its variance. We also present results of characterization for the front-end electronics and for the analog-to-digital converters in the MPDs, which were required to implement the MAPMT data acquisition system.

    The Neutrinos Angra (ν-Angra) Experiment aims to construct an antineutrinos detection device capable of monitoring the Angra dos Reis nuclear reactor activity. Nuclear reactors are intense sources of antineutrinos, and the thermal power released in the fission process is directly related to the flow rate of these particles. The antineutrinos energy spectrum also provides valuable information on the nuclear source isotopic composition. The proposed detector will be equipped with photomultipliers tubes (PMT) which will be readout by a custom Amplifier-Shaper-Discriminator circuit designed to condition its output signals to the acquisition modules to be digitized and processed by an FPGA. The readout circuit should be sensitive to single photoelectron signals, process fast signals, with a full-width-half-amplitude of about 5 ns, have a narrow enough output pulse width to detect both particles coming out from the inverse beta decay (bar nue+p → n + e+), and its output amplitude should be linear to the number of photoelectrons generated inside the PMT, used for energy estimation. In this work, some of the main PMT characteristics are measured and a new readout circuit is proposed, described and characterized.

    Nunes, G K M; Santos, S B

    2012-02-01

    The distribution and abundance of terrestrial molluscs are affected by environmental factors, but data are lacking for Brazilian land snails. The aim of this study was to understand the relationship between measured environmental factors and the land-snail species composition of two hillsides covered with Atlantic Rain Forest on Ilha Grande. On each hillside, five plots located at 100 m intervals between 100 to 500 m asl were chosen. Each plot was sampled by carrying out timed searches and collecting and sorting litter samples from ten quadrats of 25 × 75 cm. A range of environmental data was measured for each of the quadrats in a plot. A Cluster Analysis was carried out for the richness and abundance data. The environmental variables were analysed using a Pearson Correlation Matrix and Discriminant Analysis. Our results show that the two mountains are similar in species richness, but species composition and abundance are different, probably reflecting observed differences in environmental conditions. The environmental factors associated with compositional variation between the two mountains were: atmospheric temperature, soil temperature, litter depth, and relative air humidity. Distinct luminosity and canopy closure conditions were related to the composition of the land-snail community of one hillside. PMID:22437388

  9. Risk perception of workers at nuclear power plants from Angra dos Reis, Rio de Janeiro State: preliminary study of a reality on health

    International Nuclear Information System (INIS)

    The present paper analyses some social and occupational parameters that may have an influence on the risk perception levels of the workers in Brazilian Nuclear Power pLants, emphasizing possible relationship between the specificity of job tasks/literacy and risk perception. This study was based on two findings from the scientific literature: risk perception increases proportionally with literacy; risk perception decreases proportionally with the specificity of job tasks. The results of this pilot study indicates that risk perception levels of the workers in Brazilian Nuclear Power Plants increases proportionally with the literacy and specificity of their job tasks, contrasting with the american and european profiles. These results appears as a singular reality of those workers and the possibility of a new regard over the management and decision making process in the Brazilian Nuclear Power Plants. (author)

    The geochemistry dispersion of the metals in aquatic environment is related to the physical chemistry proprieties of these elements as to their interaction by sorption on and desorption from solid particles. These interaction must be understood within the environmental dynamic, with its hydrological, sedimentological, chemical, physical and biological processes that may take the toxic elements (stables metals and radionuclides) to the bio alimentary chain. It was observed at the Ribeira Bay, its hydrodynamic behaviour through the suspension material and particulate organic carbon dispersion. And, through the textural, mineralogical and chemical parameters it was observed the behaviour of the geochemistry processes of the sedimentary materials and the influence that they may submit to the metals dispersion.

The purpose of this program is to define a monitoring trend to assess the off-site radiological conditions and give support to decision making for implementing protective measures in case of a radiological incident, taking into account atmospheric diffusion, population conglomerates and their habits, water and land use, contemplating the entire Emergency Planning Zone of 15 Km radius

  12. A study on the external dose rates around of the nuclear plant of Angra I

    International Nuclear Information System (INIS)

    The Laboratory for Environmental Monitoring of Electronuclear monitors the external dose rates around Angra Nuclear Power Plant, regarding the local radiological conditions and its implication to the environment. A monitoring program has started at 1974 and goes on up to now, taking into account terrestrial gamma radiation, aquatic and terrestrial biomass, soils, sediments and air filters analysis within an effective area of more than 30 Km around the nuclear reactor under operation. Concerning external exposure, TL dosimetry, ionization chamber and gamma spectrometry were used. 42 monitoring stations, between the cities of Angra dos Reis and Paraty, are under operation by this time. Results indicate that actually exposure rates evaluated inside the monitoring area do not differ from typical external radiation data obtained from the State of Rio de Janeiro. A weak correlation was found between wind direction and angular external exposure distribution, indicating insignificant dispersion and deposition of man-made radionuclides from the power plant to its vicinity. On the other hand, large gradients of gamma exposure rates were found on sandy sites located at the 'directed area of impact of the reactor'. Nevertheless, the absence of artificial radionuclides and the large variations of natural ones suggest the sedimentary marine dynamics as the major agent. (author)

    International Nuclear Information System (INIS)

    Angra Nuclear Power Station, Unit 1, in Angra dos Reis, RJ, Brazil, with a PWR - Pressurized Water Reactor - has an installed capacity of 1876 MW thermal and 657 MW electrical. The ongoing seventh operating cycle is designed for a duration of 217 Effective Full Power Days. The Physics Tests for the cycle 7 were started on 03/dec/97, following internal technical and administrative procedures and based also on the code ANSI-ANS-19.6.1-1985-Reload Startup Physics Tests for Pressurized Water Reactors. The purpose of the Physics Tests is to confirm by measurements the predicted core parameters as stated in the Nuclear Design report for each specific cycle and the adherence to Technical Specifications. As a minimum the Physics Tests program comprises the following determinations: reactivity computer checkout, reactor coolant system boron concentration for control rods inserted and withdrawn, control rod worthies; moderator and isothermal temperature coefficient; neutron flux symmetry; zero and full power boron concentration. This paper describes the Lower Physics Tests only, that is, the tests performed between zero and around 2% power, before the admission of steam to the turbine-generator, and consequently, before the synchronism of the Unit to the electrical distribution network of the region center-south.

  14. Simulation results for light propagation in the central detector for the Angra anti-neutrinos experiment

    International Nuclear Information System (INIS)

    Full text: An antineutrino detector to be installed in the surrounding area of the Angra II nuclear reactor in Angra dos Reis is currently under development. The related experiment is intended to create a new tool capable of measuring the antineutrino flux coming from the reactor, making use of detection system placed near the reactor dome, and correlate it to the nuclear fuel fission and burn-up. The proposed detector is a box- shaped volume filled with water doped with 0.2% Gadolinium. The photons generated by the passage of particles are collected by 40 photomultiplier tubes (PMT). Aiming to evaluate the importance of reflecting inner surfaces and to provide directives concerning the best positioning of the PMTs inside the detector, a simulation of light propagation in its active volume has been done. Photons are supposed to be point-like entities traveling in straight lines. In the simulation, we investigate the overall photon counting efficiency by analyzing the number of reflections and the length travelled by the photons before being collected or absorbed, as well as the distribution of these photons in different configurations of the PMTs. Different light reflecting structures around the PMTs are also simulated, in order to find those that reduce the probability for a photon to be bounced back to the direction from which it was emitted. We show that a configuration in which the photon emission direction is preserved may be used as VETO for cosmic events. (author)

    Full Text Available O artigo analisa aspectos econômicos da elite colonial mineira a partir de meados do século XVIII, mediante a investigação empírica da sociedade de São João Del Rei. O comércio em São João assumiu um papel central na liquidez da economia regional, permitindo a formação de grupos hegemônicos no século XIX. Mas há ainda muitas dúvidas sobre quem era essa elite no século XVIII. Com base em pesquisa prosopográfica que reconstrói os caminhos dos homens arrolados por Domingos Nunes Vieira como os mais ricos da capitania de Minas Gerais no ano de 1756, percebemos que a elite mineira que se formou no século XVIII diferia dos padrões mais gerais para a caracterização de grupos hegemônicos em outras regiões do Brasil, no mesmo período

  1. Integrity evaluation of the pressure vessels of Angra-2 and Angra-3 reactors by stress analysis

    International Nuclear Information System (INIS)

    The integrity of the reactor pressure vessel of the unit II/III of the Nuclear Power Station at 'Angras do Reis' is evaluated by stress analysis, through the dynamics relaxation method. For the solution of the problem an axisymmetric model is fixed. Initially, the data of the Oak Ridge Vessel V-7 is compared with those obtained by two computer programs used in this study. The methods used in the computer programs are FEM and DEM. A11 the results are compared with the ASME Code Section III 1974 edition. The range deviation is determined to 99% confidence limit, in order to minimize the error probabilities. Finally, the equivalent intensity stress obtained is calculated and compared with the acceptable values of the ASME Code Section III, 1974 edition

  2. Dispersion modeling of atmospheric contaminants in the Angra Nuclear Power Plant using LES and a new model for the CBL growth

    International Nuclear Information System (INIS)

    In the present work we report a comparison between experimental data and GILTT approach to simulate radioactive contaminant dispersion in the Atmospheric Boundary Layer using micrometeorological parameters generated by LES (Large Eddy Simulation) in the area around the Angra dos Reis Nuclear Power Plant. Furthermore, starting from the evolution equation for the turbulent energy density spectrum (EDS), we develop a new model for the growth of the turbulence in Convective Boundary Layer (CBL). We apply dimensional analysis to parameterize the unknown inertial transport and convective source term in the dynamic equation for the three-dimensional (3-D) spectrum. The non linear integro-differential equation is solved by Adomian decomposition method. The one-dimensional vertical spectrum is derived from the 3-D spectrum, employing a weight function. This allows us to select the magnitude of the vertical spectral component for the construction of the growing 3-D. Using the micrometeorological parameters generated by LES, for the first time, we employ the vertical component of the energy spectrum to calculate the eddy diffusivity (required in dispersion models). This new eddy diffusivity is used in the simulations of the ground-level concentrations considering experimental data of the Nuclear Power Plant. (author)

  3. ANGRA-1 probabilistic safety study

    International Nuclear Information System (INIS)

    For the establishment of interim safety goals a methodology for calculating consequences and risks associated with the Angra-1 operation was developed. The most important contributors to the core melt frequency are two occurrences. The first is loss of main feedwater whose contributions correspond to 66.4% of the total core melt frequency calculated for two years of data collection. The second major contributor is a loss of offsite power case which contributes 33.2% of the total. The development of emergency procedures for addressing severe accidents consist of proposals to help in delaying and minimizing the release of radioactive products to the environment. The Angra-1 PSS calculated the less reliable lines as being the hot legs suction lines. The interface LOCAs contribution to the consequences can be reduced by the improvement of the reliability of the hot legs suction lines through the installation of extra isolation valves.

    Porphyrin rings containing two meso-pyridyl groups either in cis or trans fashion can be used to construct Re(I) bridged multiporphyrin assemblies. The cis-dipyridyl porphyrins with various porphyrin cores such as N4, N3O, N3S, N2S2 have been used to react with Re(CO)5Cl in THF at refluxing temperature and constructed planar Re(I) bridged porphyrin dyads containing either one type of porphyrin subunit or two types of porphyrin subunits. The trans-dipyridyl porphyrins have been used to construct Re(I) bridged porphyrin squares. The porphyrin dyads have been explored for singlet-singlet energy transfer studies and porphyrin squares have been used for catalysis, chemical sensing, molecular sieving and photocurrent production studies. An overview of synthesis of Re(I) bridged porphyrin dyads, triads and tetrads and their interesting photophysical properties are highlighted in this paper.

    The efficient operation of a Nuclear Power Plant (NPP) requires the continuous identification of derivations in the main operating parameters. The identification and analysis of those derivations allow someone to detect the degradation of instruments or even of any equipment. In order to study this problem the group of thermal generation of Angra 1 NPP, devised the use of a Microsoft Excel spread sheet for the automation of Angra 1 thermal balance. In the set of simulation spread sheets, measured values of the secondary system main parameters were compared with project values for a given reactor power level and condenser pressure. The spread sheets provide the turbines power and efficiency and do the plant thermal balance. This work presents a general description of the spread sheets set and a real case analysis of Angra 1 NPP, showing its precision and use easiness. (author)

  12. Atmospheric dispersion in complex terrain: Angra-1 nuclear power plant

    International Nuclear Information System (INIS)

    The Angra 1 plant is located in a very complex terrain, what makes the environmental impact assessment very difficult, regarding to the atmospheric transport problem as well as to the diffusion problem. Three main characteristics are responsible for that situation: the location at the shoreline, the complex topography and the high roughness of the terrain. Those characteristics generate specific phenomena and utilization of parameters from other sites are not convenient. Considering financial and technical viabilities, we must look for the local parameters, disregarding the easy, although risky, attitude of applying parameters and models incovenient to the Angra site. Some of those aspects are more important, and among them we will discuss the Plume Rise, the Critical Height, the Drainage Flow and the Atmospheric Dispersion Coefficients. (Author)

    International Nuclear Information System (INIS)

    An economical assessment of Angra 1 fuel cycle stretch-out is performed by means of NUCOST 1.0, a PWR power cost calculation code. International basic costs and an interest rate of 10%a were utilized. During the natural part of the fuel cycle an hypothetical capacity factor of 70% and in the stretch-out part a decrease in Plant's thermal efficiency have also been taken into account. The neutronic data were generated by FASER, MULTIMEDIUM, MEDIUM and PINPOW code system, simulating Angra 1 in the CAOC (constant Axial-Offset Control) operation. Assumming no proplems in the Plant's strecth-out phase, an optimum extension pont of 1 MWd/kg would be attained, what affords an US$700,000 savings by cycle when fuel and operation and maintenance costs are considered.

  5. Monitoring Nuclear Reactors with Antineutrino Detectors: The ANGRA Project

    International Nuclear Information System (INIS)

    Nuclear reactors are intense source of antineutrinos and the thermal power released in the fission process is directly related to the emitted antineutrino flux. As antineutrinos interact very weekly with matter and escape the reactor containment without any significant change in their number, measuring the antineutrino flux can give quasi real time information on the reactor status (on/off) and thermal power. Furthermore as the amount of fissile elements change during the burn up of the nuclear fuel and each fissile isotope has a characteristic antineutrino energy spectrum, measuring the antineutrino energy spectrum escaping the reactor can give also information on the composition of the nuclear fuel. These unique features make antineutrino detectors good candidates to become in the near future a new safeguards tool for monitoring nuclear reactors through counting rates and spectral antineutrino measurements. We will present the status of the ANGRA Neutrinos project, aimed at developing an antineutrino detector for monitoring nuclear reactor activity. The Angra experiment will be deployed at the Brazilian nuclear power plant Angra II. A water Cherenkov detector of one ton target will be placed in a commercial container just outside the reactor containment, about 30 m of the reactor core. The 4 GW thermal power of the Angra II reactor will provide a few thousand antineutrino inverse beta decay interactions per day. The main challenge of the experiment will be to overcome the very high cosmic ray induced background at sea level, consisting mainly of muons, neutrons, gammas and electrons. We have estimated a muon flux of the order of 350 Hz and a neutron flux of about 4 Hz (left after the polyethylene shielding) in the target region. To overcome the background the detector will consist of three subsystems: 1) a muon veto 99% efficient placed in the outer most detector layer; 2) a neutron shield 30cm thick consisting of polyethylene sheets; 3) a central detector

    Angra 1 considers the Self-Assessment concept an extremely valuable tool to enhance plant safety and plant performance. A formal guidance procedure to apply this methodology does not exist at our plant and should be developed and implemented as soon as possible. Some portions of this methodology already exist with different names. The root cause analysis of in-house incident reports is a heavy portion of a sound self-assessment approach. International related experience from top performance plants should be used. International meetings, such as this one, should be convened and formal guidance from the IAEA should be written

  7. Neutronic calculations for Angra-1 steam line break accident

    International Nuclear Information System (INIS)

    The reduction of boron concentration in the Boron Injection Tank (BIT), to the room temperature solubility level, makes necessary a reanalysis of the steam line break accident of Angra 1 NPP. This paper describes the neutronic calculation related to this reanalysis. The main steps of the work were: review of reactivity parameters used in the accident simulation; search of xenon profiles that cause the most severe core power distribution; calculation of hot channel factors and other neutronic parameters necessary for DNBR determination. The final conclusion, related to the steam line break accident, states the BIT concentration may be reduced to 2000 ppm. (author)

  8. The relevance of PSA during shutdown conditions for the Angra-1 NPP

    International Nuclear Information System (INIS)

    In view of the issuance of the Authorization for Permanent Operation of the Angra-1 Nuclear Power Plant, the Brazilian Regulatory Body (CNEN) is requiring a Probabilistic Safety Assessment (PSA) level 1 to be performed by the Utility (FURNAS), which should consider shutdown conditions within its scope. Angra-1 PSA is part of a Safety Improvement Programme under implementation. An analysis of Angra-1 power history, covering the last eight years of operation, has shown that 56.7% of this period corresponds to shutdown operational modes. Regarding the same period, an Analysis of Angra-1 operational experience was performed to select potential initiating events during shutdown conditions. Within the Safety Improvement Programme, a complete review of Angra-1 Technical Specifications should be carried out making use of the PSA results. The inclusion of Limiting Conditions for Operation during shutdown modes is expected to be recommended. The objective of this article is to point out, based on an analysis of Angra-1 operational experience and power history, covering the last three cycles, the relevance of requiring shutdown conditions to be included in the Angra-1 PSA scope.

    1982-10-15

    This work studies the following aspects related to the interaction of the Angra I power plant with the Furnas electric network: reliability of alternative sources, 500 kV and 138 kV systems and emergency diesel generators; operation capacity of Angra I and performance of Angra I and the future power plants Angra II and III. In the first part, after the Furnas network and the main systems of the Angra I power plant (specially the electrical system) have been analysed, the reliability for each source was computed separately and then the results lumped together. The reliability computation for the 500 kV system was done employing the computer code CST-ELETROSUL (reliability or transmission system) and for the remaining computations the fault tree theory was used, resulting in a number that represents the approximate value of the alternative sources, referring to the assumed considerations. In the second part, some limitations in the operation capacity of Angra I were verified, suggesting that the power plant should operate in base-load for safety reasons. In order to determine the factors that define the performance of a Nuclear Power Plant, FDIS, FCON, FINP and FIP, the works already accomplished by Centrais Eletricas Brasileiras S/A - ELETROBRAS were taken as a basis and were implemented with more recent data about operation of the nuclear power plant PWR. The computer code SPSS (Statistical Package for the Social Sciences) was utilized for obtaining the factors concerning to power plant with the capacity of Angra I, II and III. From the obtained valves and with the static generation capacity theory, were composed the load permanency curves from the unity 1 and for the three unities lumped together in the CNAA site.

  11. Preoperational environmental monitoring of the Angra reactor site

    International Nuclear Information System (INIS)

    The Preoperational Environmental Monitoring Program for the Angra Nuclear power plant site as well as the single and summarized results obtained this program are presented and discussed in this report. For clarity, a description is given of the Angra site and of the program structure and a map of the region showing measurement and sampling locations is included. Preoperational monitoring was carried out over the period from September 1979 to September 1981. For direct measurements of background radiation levels a solid-state dosimeter network was used and the results were compared to measurements made with ionization chambers. Measurements were performed of natural and artificial radioactivity concentration levels in air, surface water, soil, grass, sea sediments, sea algae and various foodstuffs. Gross alpha and beta activity levels were determined as well as the concentration levels of individual natural radionuclides. The presence of cesium-137 originating from fallout was observed in manioc. Minimum detection limits for fission and activated corrosion products which are of interest during the reactor operational period were defined and determined for the instrumentation and methods used at the Institute of Radioprotection and Dosimetry. These limits have been included in the tables. (Author)

  13. Analysis of liquid radioactive wastes of Angra-1 reactor

    International Nuclear Information System (INIS)

    Any activity that produces or uses radioactive materials generates radioactive wastes. Normal operation of nuclear power plant produces radioactive waste that can be in gas, liquid or solid form and its level of radioactivity can vary. Gases and liquids wastes are treated and released into environment. The main source of radioactivity released to environment from Angra 1 are liquids from Waste Monitor Tanks. Those releases are under administrative control to meet the discharge limits established by Comissao Nacional de Energia Nuclear (CNEN). A representative sample of each batch is taken for analysis for principal gamma- emitting radionuclides and, if the analysis indicate that release can be made, the quantity of activity is recorded. Within the licensing process of Angra 1, monthly a proportional composite samples are made up with a aliquot of each batch and sent to Instituto de Radioprotecao e Dosimetria (IRD) to analyze and compare with the results reported. This comparative analyses showed that when the activity of that samples was very high, the activity measured on composite samples was higher than the sum of the activities measured on each batch. The operator was advised and requested to identify and solve the problem. This work presents the problem occurred and the solution found to improve the performance of measurements. (author)

  19. The nuclear safety culture approach at Angra 1 NPP

    International Nuclear Information System (INIS)

    TMI-2 and Chernobyl accidents. What did they have in common? TMI-2 was an American design Reactor, with full steel containment and several special design characteristics such as independent and separated safety and protection sets, with a hard licensing process through US NRC and even though suffered an accident that completely destroyed the primary plant, with the melting of the greatest portion of the nuclear fuel. Chernobyl 4 was a Soviet design reactor, type RBMK, with no containment, a questionable design, and exploded in 1986, aproximately seven years after TMI-2 accident. If a sound safety culture would have be presented during the design and the operation of both plants, those accidents would have never occurred. The post-accidents findings: The Kemmeny commission and the required action plants to implement the lessons learned post TMI-2 focused on design and operational problems. Safety culture in Angra 1: We translated to Portuguese the document INSAG-4 and INSAG-6 and included those topics as subjects to be tought during the annual general retraining for all personnel. We choose one area-chemistry section- to undergo a pilot program for self assessment/self checking. We developed a series of safety indicators that are collected monthly and discussed in a regular meeting with the heads of the divisions. Some examples are: number of alarms lit at MCB; number of controllers in manual; Rate of installation and removal of temporary modifications; calculated alowable time within a LCO and attendance to recommendations according to internal event reports and to QA findings. It is a continuous, on going task. Everyone in the organization must understand that and shall be part of it. We at Angra 1, are giving some important steps towards that objective. There are still room for improvements. We are aware of that. (author)

    This paper proposes a systematic approach for dynamic power system equivalents based on power transfer distribution factors. The proposed method divides the original network into an internal interconnected system and an external one. Static equivalents are computed at frontier buses that separate the retained internal system from the external one. The equivalents are formed using REI (Radial, Equivalent and Independent) networks and generator model aggregation. Generator parameters are computed based on power transfer distribution factors of the generated active power. The equivalent models are able to accurately approximate the behavior of the original system for short circuit and transient stability analyses. Two test systems, namely the Kundur's 2-area test system and a 1213-bus network that model a real transmission system are used to illustrate and test the proposed technique. (author)

    This paper presents an economic-financial evaluation of 'Angra 3 Nuclear Power Plant' project and estimates the lowest power tariff value at which power potentially made available may be commercialized and yet ensure the project a profitability level agreeable to the interests of economic agents and shareholders. According to the 'project evaluation' practice, Angra 3 power generation was considered separately from ELETRONUCLEAR's operating plants (Angra 1 and Angra 2), thus preventing result distortions bound to occur if the economic-financial variables of the new project were analyzed associated with financial commitments and commercialization conditions resulting from the project implementation process and the generated power commercialization conditions, respectively. For this evaluation different technical and economic scenarios were devised, and the theory of Capital Asset Pricing Model for Own Capital cost and that of Weighted Average Cost of Capital were used in addition to the forecast of the Statement of Results and Free Cash flow of Shareholders throughout the power plant life, which is the estimate basis for the lowest power tariff value and the Internal Return Rate of the project. The evaluation conclusion is that Angra 3 project is technically and economically feasible and competitive as compared to the new large power generation projects planned for power supply in Brazil in the next decade, mainly in the Southeast.

    We describe the status of the ANGRA Project, aimed at developing an anti-neutrino detector for monitoring nuclear reactors. Indeed the detection of anti-neutrinos provides a unique handle for non-invasive measurements of the nuclear fuel. This kind of measurements are of deep interest for developing new safeguards tools which may help in nuclear non-proliferation programs. The ANGRA experiment, placed at about 30 m from the core of the 4 GW Brazilian nuclear power reactor ANGRA II, is based on a water Cherenkov detector with about one ton target mass. A few thousand antineutrino interactions per day are expected. The latest results from simulations and the status of the construction are presented. (authors)

    In Brazil the regulatory body is CNEN (Comissao Nacional de Energia Nuclear), according to its requirements, when there is not a Brazilian standard, the utilities shall follow the requirements of the designer. For Angra 1, the designer is an American company - Westinghouse. So, the requirements for dedication of U.S. NRC (United States Nuclear Regulatory Commission) shall be applied, these requirements are in 10CFR21 - Reporting of Defects and Noncompliance. According to 10CFR21, when applied to nuclear power plants licensed dedication is an acceptance process undertaken to provide reasonable assurance that a commercial grade item to be used as a basic component will perform its intended safety function and, in this respect, is deemed equivalent to an item designed and manufactured under a quality assurance program standard for nuclear power plant. This assurance is achieved by identifying the critical characteristics of the item and verifying their acceptability by inspections, tests, or analyses by the purchaser or third-party dedicating entity.

    The Response Evaluation in Neurofibromatosis and Schwannomatosis (REiNS) International Collaboration was established with the goal to develop consensus recommendations for the use of endpoints in neurofibromatosis (NF) clinical trials. This supplement includes the first series of REiNS recommendations for the use of patient-reported, functional, and visual outcomes, and for the evaluation of imaging response in NF clinical trials. Recommendations for neurocognitive outcome measures, the use of whole-body MRI in NF, the evaluation of potential biomarkers of disease, and the comprehensive evaluation of functional and patient-reported outcomes in NF are in development. The REiNS recommendations are made based on current knowledge. Experience with the use of the recommended endpoints in clinical trials, development of new tools and technologies, new knowledge of the natural history of NF, and advances in the methods used to analyze endpoints will likely lead to modifications of the currently proposed guidelines, which will be shared with the NF research community through the REiNS Web site www.reinscollaboration.org. Due to the clinical complexity of NF, there is a need to seek expertise from multiple medical disciplines, regulatory agencies, and industry to develop trial endpoints and designs, which will lead to the identification and approval of effective treatments for NF tumor and nontumor manifestations. The REiNS Collaboration welcomes anyone interested in providing his or her expertise toward this effort. PMID:24249805

At the current stage of the project, 40 PMTs are expected to be used. These should be characterized and have their performance parameters periodically evaluated. The electronic system for data acquisition used in the measurements of the PMT gain was developed from a Data Processing Module (MPD), composed by analogue to digital converters that are controlled by a high speed Field Programmable Gate Array (FPGA) and transmits data to a computer using an interface designed to communicate via the Universal Serial Bus (USB). A preamplifier circuit with waveform shaping capability is necessary to capture the voltage pulse generated by particle detection. Both the PMT characterization and the neutrino detection require the observation of single photoelectron, as a signal with amplitude of few millivolt and duration shorter than 50 nanosecond, with electrical charge around 1.6 picocoulomb. In this work we present the whole data acquisition chain, with particular emphasis on the design of the preamplifier circuit and on the measurement of the single photoelectron spectrum from which the PMT gain is estimated. Results for 4 PMTs are presented and discussed, along with a description of the software - developed under the Linux operational system, using C++ language on the ROOT/CERN [http://root.cern.ch] platform - used to implement the data acquisition and analysis.

  12. Analysis of the rod drop accident for Angra-1

    International Nuclear Information System (INIS)

    The aim of this work is to present a rod drop accident analysis for the third cycle of the Angra-1 nuclear power plant operating in the automatic control mode. In this analysis all possible configurations for dropped rods caused by a single failure in the controller circuits have been considered. The dropped rod worths, power distributions and excore detector tilts were determined by using the Siemens/KWU neutronic code system, in particular the MEDIUM2, PINPOW and DETILT codes. The transient behaviour of the plant during the rod drop event was simulated with the SACI2/MOD0 code, developed at CDTN. Determinations related to the DNBR design limit were conducted by utilizing the CDTN PANTERA-1P subchannel code. The transient analysis indicated that for dropped rod worths greater than about 425 pcm reactor trip from negative neutron flux rate will take place independently of core conditions. In the range from 0 to 425 pcm large power overshoots may occur as a consequence of the automatic control system action. The magnitude of the maximum power peaking during the event increases with the dropped rod worth, as far as the control bank is able to compensate the initial reactivity decrease. Thermal-hydraulic evaluations carried out with the PANTERA-1P code show that for all the relevant dropped rod worths the minimum DNBR will remain above a limit value of 1.365. Even if this conservative limit is met, the calculated nuclear power peaking factors, FNAH, will be at least 6% higher than the allowable FNAH-values. Therefore, the DNBR design margin will be preserved at the event of rod drop. (author)

  13. Echoes of Portuguese Navigation in the Kitab-i Bahriye by Piri Reis

    Directory of Open Access Journals (Sweden)

    Rui Manuel Loureiro

    2013-10-01

    Full Text Available The world map drawn by Piri Reis in 1513, of which only the Atlantic fragment kept in Istanbul is known, is justly famous. Its surprising modernity is fully explained by the use of Iberian sources, resulting from nearly a century of exploration of both sides of the Atlantic by Portuguese and Spanish navigators, along with other collaborators. The ‘Book of maritime affairs’, prepared in the 1520s by the Turkish cartographer, gathering precious geographic and cartographic information about the Mediterranean and many other regions, is equally important, although rather less well known. In the foreword to his Kitab-i Bahriye, Piri Reis appears to be especially well informed about Portuguese explorations along the African coast and in the Asian seas, after the voyages of Bartolomeu Dias and of Vasco da Gama. Is it possible to identify the textual and cartographic sources used by Piri Reis in the preparation of both his cartographic works?

    The purpose of this work is to present a new model of the alarm annunciation system of the Angra 2 nuclear power plant, using concepts of object based modeling and having as basic the Angra 2 Systems and Components Identification System - KKS. The present structure of the Computerized Alarm System - CAS of Angra 2 does not permit a fast visualization of the incoming alarms in case that a great number of them go off, because the monitors can only show 7 indications at a time. The herein proposed model permits a fast identification of the generated alarms, making possible for the operator to have a general view of the current nuclear power plant status. Its managing tree structure has an hierarchical dependence among its nodes, from where, the presently activated alarms are shown. Its man-machine interface is easy interaction and understand because it is based on structure well known by the Angra 2 operators which is the Angra 2 Systems and Components Identification System - KKS. The project was implemented in the format of an Angra 2 Alarms Supervision System (SSAA), and, for purpose of simulation, 5 system of the Angra 2 Nuclear Power Plant have been chosen. The data used in the project like measurement KKS, measurement limits, unity, setpoints, alarms text and systems flow diagrams, are actual data of the Angra 2 Nuclear Power Plant. The Visual Basic programming Language has been used, with emphasis to the object oriented programming, which and modification, without modifying the program code. Event hough using the Visual Basic for programming, the model has shown, for its purpose, a satisfactory real time execution. (author)

  20. The marine environment monitoring in Saco Piraquara de Fora after the beginning of the Angra 2 nuclear power plant operation

    International Nuclear Information System (INIS)

    The goal of this paper is to evaluate the environmental monitoring around the Almirante Alvaro Alberto Nuclear Power Station after the beginning the operation of Unit II, in July 2000. The Environmental Monitoring Laboratory collects several environmental samples and analyses them radiometrically to determine the presence of artificial radionuclides. In the Environmental Monitoring Laboratory, the samples are prepared and analysed following international procedures and the activities of the detectable radionuclides are obtained by gamma spectrometry. The Environmental Monitoring Laboratory analyses tritium in sea water as well. This paper will describe only the monitoring of the marine samples and the results of the measurements are compared with those obtained in pre-operational time of Angra 1 (1978 - 1982), Angra 2 (1996 - 2000) and those obtained in operational time of the units until 2008. The results show that, since 1982 until now, there is no impact on marine environment caused by the operation of Angra 1 and Angra 2. (author)

  8. A first accident simulation for Angra-1 power plant using the ALMOD computer code

    International Nuclear Information System (INIS)

    The acquisition of the Almod computer code from GRS-Munich to CNEN has permited doing calculations of transients in PWR nuclear power plants, in which doesn't occur loss of coolant. The implementation of the german computer code Almod and its application in the calculation of Angra-1, a nuclear power plant different from the KWU power plants, demanded study and models adaptation; and due to economic reasons simplifications and optimizations were necessary. The first results define the analytical potential of the computer code, confirm the adequacy of the adaptations done and provide relevant conclusions about the Angra-1 safety analysis, showing at the same time areas in which the model can be applied or simply improved.

  9. An experience of marine macrofouling control in Angra 1 - Almirante Alvaro Alberto nuclear power plant

    International Nuclear Information System (INIS)

    One of the greatest problems at the Power Plants that use sea water in the circulating water system, is the development of fouling in its sections. In Central Nuclear Almirante Alvaro Alberto - Angra 1, this fouling is represented by barnacles. These barnacles have contributed significantly to the damaging in the condenser tubes, resulting in the changing from cooper alloy tubes to Titanium ones. To help the understanding of the development and control of fouling, some researches and observations have been made using techniques adequated to Angra 1. The low-level continuous chlorination, the water flux variation and the continuous cleaning tubes system (AMERTAP) combined and used in circulation water sistem, showed satisfactory preliminar results in fouling control.

  11. Economical analysis of the second partial reload for Angra 1 with partial low-leakage

    International Nuclear Information System (INIS)

    Preliminary results for the Angra 1 second reload design with partial low-leakage were assessed with NUCOST 1.0, code for nuclear power costs calculation. In the proposed scheme, some partially burned fuel assemblies (FAs) are located at the core boundary, while new FAs occupy more internal positions. The nuclear design - utilizing the code system SAV (from Siemens/KWU Group, F.R. Germany) - has been performed with detail for the 3rd cycle while simpler approach has been utilized for subsequent reloads. Results of NUCOST 1.0 show that the partial low-leakage reload in the 3rd cycle of Angra 1 offers fuel costs 1% lower when compared to the Plant's actual reload scheme, what corresponds to an savings of about US$190.000. When operation and maintenance and capital costs are also considered, economies in the order of US$2.6 million are obrained. (author)

  14. Flow accelerated corrosion programme in Angra nuclear power plants Units 1 and 2

    International Nuclear Information System (INIS)

    Almirante Alvaro Alberto Nuclear Power Plant, referred herein as Angra NPP, comprises two generating units operated by ELETROBRAS Termonuclear S.A. - ELETRONUCLEAR. Unit 1, a Westinghouse designed PWR, operates commercially since 1982 generating 657 MW, while unit 2, designed by Siemens, is a 1350 MW PWR in operation since 2000. Flow Accelerated Corrosion (FAC) programme integrate a set of ageing related programmes established to control ageing effects on equipment and piping in order to ensure their capability to perform their functions during the plant remaining life. The objective of this paper is to describe ELETRONUCLEAR experience in developing and implementing a programme related to Flow Accelerated Corrosion, with focus on piping of the secondary sides of Angra NPP, explaining in detail the current situation for important pipings, and presenting updated results of the FAC control. Accurate inspections are the basis for an effective FAC programme. Wall thickness measurements establish the extent of wear in a given piping, providing data to support FAC trends, and to refine the predictive model. A permanently and clearly identify grid is makes re-inspection possible, at any time, at the same points. Supported by the computational system Comsy, some of its features as FAC potentially susceptible lines identification, wall thinning rates determination, inspection data recording, wear rates analyses, lifetime prediction and inspection scheduling will be showed in detail. This programme has started in 2004, and since this time it was applied in a total of six outages in Angra 1 NPP and three outages in Angra 2 NPP, with a large number of piping elements inspected and analyzed. Some of these results will be showed and discussed in this paper, regarding the potential of Flow Accelerated Corrosion occurrence. (author)

    2012-01-01

    Full Text Available In this work, Probabilistic Safety Assessment (PSA is used to evaluate Allowed Outage Times (AOT and Surveillance Test Intervals (STI extensions for three Angra 1 nuclear power plant safety systems. The interest in such an analysis lies on the fact that PSA comprises a risk-based tool for safety evaluation and has been increasingly applied to support both the regulatory and the operational decision-making processes. Regarding Angra 1, among other applications, PSA is meant to be an additional method that can be used by the utility to justify Technical Specification relaxation to the Brazilian regulatory body. The risk measure used in this work is the Core Damage Frequency, obtained from the Angra 1 Level 1 PSA study. AOT and STI extensions are evaluated for the Safety Injection, Service Water and Auxiliary Feedwater Systems using the SAPHIRE code. In order to compensate for the risk increase caused by the extensions, compensatory measures as (1 test of redundant train prior to entering maintenance and (2 staggered test strategy are proposed. Results have shown that the proposed AOT extensions are acceptable for two of the systems with the implementation of compensatory measures whereas STI extensions are acceptable for all three systems.

  20. Public relations strategy for the completion of Angra 2 nuclear power plant

    International Nuclear Information System (INIS)

    In the 60's, the general public in Brazil knew little about nuclear energy. The country was under Military Rule since 1964 and, in the public's ind, the Nuclear Program was closely linked to nuclear weapons, being viewed with distrust and, even, fear. Governmental policies in this field were secret - when the decisions were made to built Angra 1 in 1968 and to sign the Nuclear Cooperation Agreement with Germany in 1975 - the public learned about them as a 'fait accompli'. In the late 70's, people started to hear about the delays in the commissioning of Angra 1 and the problems in the construction of the pile foundations of Angra 2. In 1980, following the TMI accident, the Federal Government issued a set of regulations dealing with emergency planning, the Federal and State Civil Defense being responsible for the preparation of the Off-Site Emergency Plan. FURNAS first public information campaign in 1982 dealt with emergency procedures and was directed to the Angra NPP employees and their families; local residents were visited by Civil Defense officials in 1983. At that time, the Brazilian Nuclear Program began to be criticized by concerned scientists and by the press, primarily due to its lack of transparency and its large scope. Safety issues arising from the TMI accident, lack of decision for the radioactive waste storage and problems with some equipment and components that delayed the commissioning of Angra 1, were pointed out as technical arguments against the construction of Angra 2 and 3. A new Constitution, 1988, required that a nuclear projects must be approved by the National Congress and put forward some new provisions for the environmental licensing of major industrial installations. The completion of Angra 2 was considered of the utmost importance by the Brazilian Nuclear Energy Association - ABEN, which is a technical-scientific body comprising employees from the various organizations that form the Brazilian Nuclear Sector.

    The neurofibromatoses (NF)--including neurofibromatosis 1 (NF1), neurofibromatosis 2 (NF2), and schwannomatosis--are related tumor-suppressor syndromes characterized by a predisposition to multiple tumor types and other disease manifestations, which often result in functional disability, reduced quality of life, pain, and, in some cases, malignancy. With increasing knowledge of the biology and pathogenesis of NF, clinical trials with targeted agents directed at NF tumors have become available. Most clinical trials for patients with NF have used designs and endpoints similar to oncology trials. However, differences in the disease manifestations and natural history of NF (compared to cancers) require the development of new designs and endpoints to perform meaningful NF clinical trials. The Response Evaluation in Neurofibromatosis and Schwannomatosis (REiNS) International Collaboration was established in 2011 at the Children's Tumor Foundation meeting to achieve consensus within the NF community about the design of future clinical trials, with a specific emphasis on endpoints. The REiNS Collaboration includes 7 working groups that focus on imaging of tumor response; functional, visual, patient-reported, and neurocognitive outcomes; whole-body MRI; and disease biomarkers. This supplement includes the first series of recommendations by the REiNS Collaboration. The hope is that these recommendations will be used by members of the group and by researchers outside of the REiNS International Collaboration to standardize the measurement of outcomes and thus improve clinical trials for patients with NF. Ultimately, we plan to engage industry partners and national regulatory agencies in this process to facilitate the approval of drugs for patients with NF. PMID:24249801

  5. Beam-to-beam joints with bolted end-plate connections concerning steel platforms Angra 2 NPP

    International Nuclear Information System (INIS)

    The paper presents adopted end-plates connections as structural solution for joints in steel platforms subjected to seismic loads as well as exceptional loads due to postulated piping ruptures. The beam-to-beam bolted end-plate connections designed for Angra 2 NPP were based in allowable stresses design. Also, usual assumptions and methods in the engineering practice, concerning steel platforms for german power plants in the 80's, were considered. The adopted method is compared with the proceedings according to Eurocode 3 - Part 1-8 to verify safety margins between old and new concept. The target of this comparison is to be sure that the adopted design is enough conservative to be adopted for the next NPP - Angra 3 (similar to Angra 2), whose construction will start in 2009.

  6. Public participation in the environmental licensing process of the Angra II reactor

    International Nuclear Information System (INIS)

    Newly adopted environmental legislation in Brazil, coupled with the construction delays of the Angra II Nuclear Power Plant, raised questioning among the public on the applicability of fast licensing authorizations. To analyse this issue, a Special Commission was setup of society's representatives and of government agencies involved in the project construction and licensing. The commission took 1/2 years to reach consensus regarding the correctness of the current licensing process. The openness of the discussions, and the opportunity of interaction during such a long time, led the group members to build up unprejudiced understanding, thus achieving mutually acceptable results.

  7. Strontium and calcium determination in sea fishes in neighborhood of Angra nuclear power plant

    International Nuclear Information System (INIS)

    Strontium-90 is an important radionuclide present in the liquid effluents of the Angra Nuclear Power Plant, located in the coastline of Rio de Janeiro State. It has a long effective half-life, easy entry into food chain due to its chemical similarity to calcium and stays for a long time in solution. With the aim of calculating the concentration factor (CF) for 90 Sr and observed ratio (OR) in the most abundant local fish, it was determined the strontium and calcium content in the edible fraction of nine species and in sea water by atomic absorption spectrophotometry.

  9. Design and tests of a data acquisition system for the Angra anti-neutrinos detector

    International Nuclear Information System (INIS)

    Full text: We describe the design of a Data Acquisition System (DAQ) for the Angra antineutrino project, aimed at developing an antineutrino detector to monitor nuclear reactors through the detection of antineutrino counting rates and spectral measurements. The experiment, presently under construction, will take place at the Brazilian nuclear power plant Angra II and will detect antineutrinos generated in the fusion process of the nuclear reactor fuel. The DAQ system is designed to be able to digitize and to store all the analog signals coming from the photomultiplier tubes (PMT), after going through the front-end electronics. It is composed of VME standard electronic modules. We focus here on the design of a new VME data acquisition card (NDAQ), which will be part of the Angra DAQ. This card is composed of eight analog-to-digital channels (ADC), each one featuring 10 bits of vertical resolution and 125 MHz of sampling rate. In order to measure time between events, or between PMT pulses, an 82 ps resolution time-to-digital converter (TDC) is also included in the card. Other NDAQ features are: one 512K x 8 bits Static RAM for on-board data storage, reprogrammable data processing circuit (through the use of a Field Programmable Gate Array - FPGA), standalone operation (connecting to any computer via USB port) and a 512K x 32 bits output buffer, used to reduce dead time in the data flow. The card allows VME block read cycles, reaching the usual bandwidth of more than 20 MB/s. Considering the worst-case estimated event rate of 1kHz, comprising neutrino and muons events, the Angra project must be able to deal with 10 MB/s event rate, which is safely below the card bandwidth. The design uses off-the-shelf devices from worldwide semiconductor companies. A software framework for the DAQ is developed for Linux platforms by using standard scientific tools and languages like ROOT and C++. The NDAQ design is currently under tests. The design and preliminary results, using

  10. Broadening of axial neutron flux difference operating band in Angra I

    International Nuclear Information System (INIS)

    ANGRA I Technical Specifications requires the axial flux difference to remain within ± 5 percent band, relative to a reference value, for any power level. The reference value is the axial flux difference at a 100% power, all rods (almost) out and equilibrium Xenon distribution. This paper presents the results of several Simulations, performed by FURNAS staff aiming the validation of calculation results against the reload designer's ones. It was also proved that the Axial Flux Difference Operating band can be broadened to ''Ref. +- 6.9% ) without exce eding the limit imposed by the ''envelope-curve''. (author)

    International Nuclear Information System (INIS)

    This work analyses the electric power system of the Angra I PWR plant. It is demonstrated that this system is closely coupled with the safety engineering features, which are the equipments provided to prevent, limit, or mitigate the release of radioactive material and to permit the safe reactor shutdown. Event trees are used to analyse the operation of those systems which can lead to the release of radioactivity following a specified initial event. The fault trees technique is used to calculate the failure probability of the on-site electric power system

    Chiral transition metal complexes not only have large nonlinear optical (NLO) response but also meet the non-centrosymmetric requirement of second-order NLO materials. Therefore, chiral transition metal complexes become very active in the NLO area. Recently, the second-order NLO response of chiral dinuclear Re(i) complex 2 has been found to be 1.5 times larger than that of KH2PO4 (KDP) based on experimental measurement. However, its NLO origin has not been determined and a structure-property relationship has not been established at the microscopic level, which are very important to further improve the performance. It is found that charge transfer from metal to ligand is mainly responsible for its NLO origin. Based on complex 2, the designed complexes have remarkably large second-order NLO activity. For instance, the designed complex 9 has a very large second-order NLO response value (115.81 × 10(-30) esu), which is about 668 times larger than the organic molecule urea. Moreover, time-dependent density functional theory (TDDFT) calculations have been used to investigate their UV-Vis/CD spectra. The simulated circular dichroism (CD) spectra of the complex 2 are in good agreement with the experimental ones, which can be used to assign the absolute configurations (ACs) of chiral dinuclear Re(i) complexes with high confidence. The electronic absorption wavelengths, electron transition properties, and the second-order NLO responses strongly depend on the nature of substituent, different ligands (pyridine and isoquinoline) and their combinations. Based on NBO analysis, the interactions between [Re(CO)3Cl] fragments and ligands are of n →σ* character. PMID:27009569

  16. Proposal of a dry storage installation in Angra NPP for spent nuclear fuel

    International Nuclear Information System (INIS)

    When nuclear fuel is removed from a power reactor core after the depletion of efficiency in generating energy is called Spent Nuclear Fuel (SNF). After its withdrawal from the reactor core, SNF is temporarily stored in pools usually at the same site of the reactor. During this time, short-living radioactive elements and generated heat undergo decay until levels that allow removing the SNF from the pool and sending it for reprocessing or a temporary storage whether any of its final destinations has not yet been defined. It can be loaded in casks and disposed during years in a dry storage installations until be sent to a reprocessing plant or deep repositories. Before any decision, reprocessing or disposal, the SNF needs to be safely and efficiently isolated in one of many types of storages that exist around the world. Worldwide, the amount of SNF increases annually and in the next years this amount will be higher as a consequence of new Nuclear Power Plants (NPP) construction. In Brazil, that is about to construct the Angra 3 nuclear power reactor, a project about the final destination of the SNF is not yet ready. This paper presents a proposal for a dry storage installation in the Angra NPP site since it can be an initial solution for the Brazilian's SNF, until a final decision is taken. (author)

  17. Beyond design basis accident management related to Angra 2 nuclear power plant

    International Nuclear Information System (INIS)

    Emergency procedures, associated to beyond design basis accident management, are important issues to guarantee the safe operation of nuclear power plants, and they may use plant normal operation systems for controlling such situation. The simulation of accident critical scenarios should be developed with the aid of the most recent versions of advanced tools for thermalhydraulic analysis, in order to verify the effectiveness of plant systems in avoiding or minimizing core damage. This thesis presents the evaluation of the capabilities of a best estimate thermalhydraulic code, RELAP5/MOD3.2, for realistically simulating the application of an emergency procedure, and additional measures, for a total loss of feedwater scenario in Angra 2, a four-loop pressurized water reactor nuclear power plant operating in Brazil. The recently proposed procedure consists of a complete depressurization of the steam generator secondary side. This measure aims at enhancing the passive feed to the steam generator through the feedwater lines and feedwater tank to restore core cooling. An experiment performed at the LOB/MOD2 facility, built with a scale factor of approximately 1/700 relatively to a design similar to that of Angra 2, was the reference data basis for this activity. The results pointed to a large possibility for the control during, at least, six hours after the transient beginning. (author)

  1. Probabilistic analysis of the loss of external eletric power in Angra-1 considering uncertainty propagation

    International Nuclear Information System (INIS)

    To fullfill the needs of the probabilistic safety assessment for the Angra 1 nuclear power plant, a computer code for performing event tree analyses ETAP2, has developed in PASCAL language for the Burroughs B-6700 computer. The code employs the impact vector method. A dependency matrix is defined which allows for proper consideration of all relevant intersystem dependencies. The analyses are carried out to the subsystem (train or channel) level. The uncertainty analysis is performance on the dominant accident sequences lumped in two different groups: one for assessing the core-degradation-class frequencies and another for obtaining the core-degradation frequency concerning the initiator under analysis. For this purpose we use a discrete Monte Carlo algorithm which is faster than others available besides furnishing reliable results. The Loss-Of-Offsite power initiator analysis is presented for illustration purposes. The ETAP2 current version is implemented in the VAX 11/780 computer. (author)

  2. Unavailability of the residual system heat removal of Angra 1 by Bayesian networks considering dependent failures

    International Nuclear Information System (INIS)

    This work models by Bayesian networks the residual heat removal system (SRCR) of Angra I nuclear power plant, using fault tree mapping for systematically identifying all possible modes of occurrence caused by a large loss of coolant accident (large LOCA). The focus is on dependent events, such as the bridge system structure of the residual heat removal system and the occurrence of common-cause failures. We used the Netica™ tool kit, Norsys Software Corporation and Python 2.7.5 for modeling Bayesian networks and Microsoft Excel for modeling fault trees. Working with dependent events using Bayesian networks is similar to the solutions proposed by other models, beyond simple understanding and ease of application and modification throughout the analysis. The results obtained for the unavailability of the system were satisfactory, showing that in most cases the system will be available to mitigate the effects of an accident as described above.

  3. Probabilistic safety analysis of the containment spray system of Angra-1 reactor

    International Nuclear Information System (INIS)

    The calculation of the unavailability of the containment spray system of Angra-1, is done. The referred system has two different modes of operation (injection and recirculation) which were separately studied using the fault tree methodology. Besides equipment and human error failures, the contributions of test, maintenance and common-mode failures have also been considered. The quantitative evaluation was carried out by the computer code SAMPLE, which considers the uncertainties in the failures data and gives a distribution for the top event unavailability. The input data were obtained from the well-known Rasmussen Report. An importance analysis of the basic events of the trees was performed and a study of the viability of some suggestions for system design modification was also conducted. A comparison between the results obtained in this work and the corresponding ones in the Rasmussen Report has shown the fact that the unavailability of both systems are of the same order of magnitude.

  4. Preliminary evaluation of the stress analysis reports for Angra I reactor coolant loop - part 1

    International Nuclear Information System (INIS)

    A methodology that will allow CNEN to approve the stress analysis reports of the components of the Brazilian nuclear power plants, was developed. The reactor coolant loop (RCL)of Angra I was checkd. This is the first part of the complete report and consists of the approval of the design documents, the approval of the equipment support models and the aproval of the steam generator dynamic model. The second part of this work is under way now and should contain the approval of the RCL stress and fatigue analysis according to ASME code section III. As shown in section 7 it appears necessary additional information from Westinghouse about the design of the RCL. (Author)

  5. Reliability analysis of the recirculation phase of the safety injection system of Angra-1

    International Nuclear Information System (INIS)

    The calculation of several reliability parameters-failure probability, unavailability and unreliability - of the recirculation phase of the safety injection system of Angra-1, was done. This system has two distinct modes of operation (short term and long term) which were fault tree analysed both separately and as a whole. To obtain quantitative results the computer codes SAMPLE and PRET-KITT were utilized. The former was used to consider the uncertainties in the failure data (drawn integrally from WASH-1400) and the latter to obtain time dependent unreliability values. Hardware failures and common-mode failures were considered. Altough the analysis methods employed here differ somewhat from those used in WASH-1400, the results which could be compared were found to have the order of magnitude. A viability study of some suggestions of system's modifications was performed, and it has shown that some significant reliability improvements can be achieved with reasonably simple changes.

  6. Analysis of the reliability of the active injection safety systems of Angra I

    International Nuclear Information System (INIS)

    The reliability of the active emergency core cooling systems of Angra I nuclear power plant is evaluated. The fault tree analysis is employed. The unavailability of the above cited systems, is calculated. A parametric sensitivity analysis has been performed, due to the existing scattering in the failure and repair rate data of these system's components. The minimal cut sets were determined and, as a final step, a reliability importance analysis has been performed. This final step has required the development of a computer program. The methodology and data from the 'Reactor Safety Study' (Wash-1400) (in which the reliability of safety systems of a tipical PWR plant is calculated), is employed. The unavailability values for the safety systems analysed are too low, thus showing that in most cases the systems analysed are available to mitigate the effects of a loss-of-coolant accident.

  7. Applied to neuro-fuzzy models for signal validation in Angra 1 nuclear power plant

    International Nuclear Information System (INIS)

    This work develops two models of signal validation in which the analytical redundancy of the monitored signals from an industrial plant is made by neural networks. In one model the analytical redundancy is made by only one neural network while in the other it is done by several neural networks, each one working in a specific part of the entire operation region of the plant. Four cluster techniques were tested to separate the entire region of operation in several specific regions. An additional information of systems' reliability is supplied by a fuzzy inference system. The models were implemented in C language and tested with signals acquired from Angra I nuclear power plant, from its start to 100% of power. (author)

  8. Cognitive workload analysis of Angra II nuclear power plant operators under design basis accidents

    International Nuclear Information System (INIS)

    This article presents an application of cognitive modelling for evaluation the workload of nuclear operator crew. The task chosen for modelling was the small break LOCA accident in Angra II nuclear power plant. In this modelling the operation teamwork is composed by a reactor operator, a turbine operator and a shift supervisor. In the simulation the correct identification of the accident type by the team during the period of automatic actions carried through the plant protection systems is considered, i.e., the identification of the accident type is carried out during the first thirty minutes after the accident beginning. The ACT-R (Adaptive Control of Thought - Rules) was used for the simulation. The article also presents the description of the basic features of ACT-R model. We conclude that, despite the approaches made in the cognitive tasks, program ACT-R is a useful instrument for cognitive analysis of operator crew. (author)

    Full Text Available Argentina's central region includes an important area covered by shallow pampean lakes and dams. In these environments, fishing of pejerrey Odontesthes bonariensis Valenciennes, 1835 (Pisces, Atherinopsidae, the most important fresh-water fish of the country, is a relevant social activity and also a considerable economic resource. The main diseases found in this species were studied from 1992 to 2003 in the provinces of Córdoba, La Rioja and Santa Fe (30º and 35º S, 61º and 67º W. Most cases were registered in high temperature months. Lernaea sp and Aeromonas hydrophila were the etiological agents most frequently found. The trophic characteristics of the aquatic environments enhanced disease processes and caused massive death of O. bonariensis, due to complex hydrochemical interactions.A região central de Argentina possui uma importante superfície coberta por represas e lagunas pampianas.

  1. Comparative xenology of two angrites

    International Nuclear Information System (INIS)

    We report the results of Xe analyses in stepwise heating of the angrite meteorite Lewis Cliff 86010 and of a comparative study of Xe component structures in this meteorite and in the first known angrite, Angra dos Reis. Both meteorites are poor in trapped Xe and rich in fission Xe from 244Pu and in spallation Xe produced by cosmic ray irradiation of Ba and the light rare earth elements (REE). Neither meteorite shows evidence for the presence of excess 129Xe derived from 129I, presumably because the volatile element iodine is depleted along with other volatiles in the angrites. Both meteorites show pronounced variations in the composition of spallation Xe attributable to separation of the Ba and REE components. In both meteorites 244Pu-derived fission Xe is correlated with REE spallation, consistent with Pu-REE coherence in igneous partitioning. The Ba spallation Xe composition in Lewis Cliff 86010 differs somewhat from that in Angra dos Reis, primarily in a lower relative yield of the neutron sensitive isotope 131Xe. This suggests a lower neutron flux during cosmic ray exposure for the Lewis Cliff Meteorite, an effect opposite to that suggested by neutron capture effects in Sm. Resolution of these observations appears to require a complex exposure history for at least Angra dos Reis. The 244Pu/REE ratio in Lewis Cliff 86010 is only about half that in Angra dos Reis. This difference probably does not reflect a difference in the time of Xe retention. Unless this difference arose in igneous processes despite the apparent chemical coherence of Pu and Ree in mineral partitioning, it must have characterized the parent magmas and/or precursor materials from which these two meteorites were derived.

    Full Text Available This text analyses João Mário Grilo’s film: O Processo do Rei (The King’s Trial (1989. Based on the trial of Afonso VI, the director was able to remain faithful to the seventeenth century historical setting, but at the same time give it a contemporary feel, while exploring eternal and recurrent aspects of the story itself. Cinema, in this film, works as a stage where the story reveals the scenography that history books habitually conceal. In order to thoroughly examine the issues raised by this text, the article discusses the relationship between cinema and theatre starting with the concept of mise en scéne. What joins and separates these two artistic forms? How has cinema built its own mise en scéne throughout its history while resorting mostly to editing?En este texto analizaré la película O Processo do Rei (1989, de João Mário Grilo.

El cine, en esta película, funciona como un escenario donde la Historia revela la escenografía que los libros de Historia acostumbran a ocultar. Para profundizar en esta cuestión comienzo por discutir las relaciones entre el cine y el teatro a partir do concepto de mise en scéne. ¿Qué aproxima, y qué distancia, a estas dos formas artísticas? ¿De qué manera el cine, a lo largo de su historia, construyó su propia puesta en escena recurriendo, sobre todo, al montaje?

  6. Vibration monitoring in Angra I nuclear power plant steam generator feedwater system

    International Nuclear Information System (INIS)

    The safety and reliability are the primary criteria in the design and operation of a nuclear power plant. However, due to the aging of the plant and its components, it is difficult to assure that what was originally built and qualified under strict standards is still guaranteed. In order to assure safety, reliability, availability and capacity, aging management through predictive maintenance techniques are being introduced in most plants around the world. In this present work, the monitoring of the vibrations signatures at the Angra I nuclear power plant steam generators feedwater systems main components such as the main feedwater pumps, pressure breaker blocks and the by pass valves, is presented. The vibration data was acquired, afterwards some major repairs were performed and during the startup commissioning procedures. Some of the major repairs performed are: changing of one pump shaft with balancing and alignment, replacement of the original bypass control valves by new disk stack type pneumatic control valves. The results show that no major vibrations anomaly is present after the maintenance indicating adequacy of the repairs made. The monitoring of the vibration in nuclear power plant components is being increasingly used as a tool for predictive maintenance. (author)

    The 3D modeling has been increasingly used in NPP - Nuclear Power Plant from its design to its life cycle management. This paper presents experiences and developments regarding the methods applied for 3D Model in the Angra 3 NPP design using proprietary software PDS® - Plant Design System, and complementary in-house software developed by ETN. A description of the adopted methodology in all disciplines such as piping, piping support, equipment, civil, steel structure, HVAC and electrical will be detailed. The PDS® system is a comprehensive, intelligent computer-aided design/engineering application for plant design, construction, and operations. The use of PDS® and the developed tools has resulted in optimization in the design process as well as the project execution. After the design phase during the erection, commissioning and start-up of the plant, the 3D Model will be strongly helpful to obtain basic data about plant components such as piping, supports, valves, equipment and pumps. They can be easily found, opened, visualized and their properties analyzed in seconds. A corresponding data-base can also provide several different information queries. Furthermore the detailed 3D Model in the as-built condition can be used during operation and in-service inspections, reducing maintenance costs and improving safety of workers. It can also be used as an additional tool in training new operators.(author)

    Angra 1 Power Plant is the first Brazilian NPP, and started its commercial operation in 1985. The wastes from its operation are spent ion exchange resins, expended filter cartridges, boric acid evaporator concentrates; and solid wastes such as gloves, cleaning tools, plastics and protective clothing. Liquid waste streams are treated by evaporation to reduce the volume, and the concentrate is solidified in cement. The original cementation unit was designed to meet the US product acceptance criteria of the early seventies, when environmental and safety requirements were less restrictive than now. This system had a very low efficiency, and the waste product quality was very poor. A new solidification plant was bought, and R and D project was carried out to study and develop a suitable cementation process and the PCP - process control program - to guarantee the licensing of the plant and maximize its efficiency using Brazilian materials. To accomplish these objectives, a huge amount of experiments were carried on. Tests were performed to determine the main properties of the process and the product, e.g. the workability, set time, compressive strength (stress resistance) and leachability. After reaching the established parameters, the mixture system was optimized. The paddle and container designs were modified and also the motor specifications, so that the process efficiency could be improved. The performance of this new system is increased allowing solidifying from 56 till 69% in volume of waste, much better in comparison of the old one, whose maximum value was about 20%. (author)

  9. Structural analysis strategies of the pressurized relief and safety valves discharge piping of NPP Angra 1

    International Nuclear Information System (INIS)

    The pressurizer relief and safety valve system provides the reactor coolant system overpressure protection and, therefore, it is fundamental for the security of a nuclear plant. This paper discusses the safety valve loop seal strategies adopted by others nuclear power plants over the world in order to attend the recommendations of NUREG-0578 (TMI-2 Lessons Learned Task Force Status Report and Short Term Recommendations). The technical option adopted for Angra 1 consists in making specific modifications on the original piping and support configuration of the pressurizer relief and safety valve system. These modifications were proposed in order to reduce the high stress levels induced by the thermal-hydrodynamic loads caused by the discharge of the sub-cooled water during the opening of the relief or the safety valves. Several thermal-hydraulic models were tested to assess the influence of the seal water heating and the simultaneous opening of the valves in order to minimize the thermal hydrodynamic loads effects. The piping structural analysis was performed, using the computer program system KWUROHR, to satisfy the requirements of the appropriate equations of the code ASME Section III, Subsections NB3650 and NC3650.

  12. Late-in-life childbearing (kōrei shussan) in contemporary Japan.

    Castro-Vázquez, Genaro

    2015-01-01

    This paper draws on interviews with a group of 27 Japanese women who were classified as late-in-life-childbearing mothers, or kōrei shussan--women who had had their first delivery at 35 years of age or over. In making sense of the significance, symbolism and consequences of late-life motherhood, the paper utilises a symbolic interactionist perspective to shed light on the cultural, structural, interpersonal and intrapsychic dimensions underpinning the experiences of this group of mothers. The paper highlights the relevance of social interaction and everyday life that make pregnancy an 'obligation' for these women. Grounded in the Foucauldian notion of normalisation, the analysis suggests that the experience of late-in-life childbearing can be understood as the result of three forms of pressure: biological, homosocial and work. The late-in-life-childbearing mother largely stems from governmental economic neoliberalism imbued with traditional conservatism and the pervasive influence of the Assisted Reproduction Treatments industry.

  17. Supervisory system for the turbine generator set of Angra 1 NPP

    International Nuclear Information System (INIS)

    The original analogue vibration monitoring system of the Steam Turbine Generator Line in Angra 1 Nuclear Power Plant had become obsolete and it was difficult to find spare parts. ELETRONUCLEAR decided to have a new digital system to substitute the original one and to provide automatic warning and prediction of developing faults. The new system was specified by the plant supporting group together with the plant engineers. It was installed to measure shaft and bearing vibrations, absolute and relative expansions as well as bearing and oil temperatures. It performs auto diagnosis, automatically interpreting all condition monitoring data to reveal and warn the staff about potential faults under development. Advanced condition monitoring may help revealing potential risks, making it possible to plan corrective actions at the scheduled production stops for safety inspections. The main goal is to increase the reliability of the production by identifying machinery problems in an early development stage and by providing the organization with information to increased safety. Already during the initial implementation phase valuable conclusions could be made for several issues such as misalignment, bearing tolerances, imbalance and bearing rub. The information directs inspections to those parts of the machine that really need it and avoids inspections where it is not required. This typically minimizes scheduled downtime for maintenance work. The system issued an automatic auto diagnosis warning about a short rub of a journal bearing during a coast down. The machine is designed to deal with these types of rub, but they should not happen repeatedly. The operators have to know about these rubs in order to conduct further analysis to determine the seriousness for future maintenance activities. The system informs whether any rubs occur, enabling them to judge whether they need to make an inspection at the next planned outage. This means, in other words, pro-active maintenance

    A steady-state neutron kinetics model of the Angra-1 NPP at BOL (Beginning Of Life) has been developed with the PARCS V2.7 neutron diffusion code. The information of the burnable poison rods, fuel enrichments and control rod banks distributions within the core have been taken from the Angra-1 FSAR (Final Safety Analysis Report) and implemented in the model. The macroscopic cross sections for the fast and thermal neutron groups have been calculated with the WIMSD-5B lattice cell code. The cross sections were obtained for the rodded and unrodded cases for each composition in the core. In order to establish the initial steady-state, an eigenvalue was made with the PARCS V2.7 code for three steady-state scenario cases reported at the FSAR; a K{sub eff} of 1.0733 was obtained for the unrodded case, K{sub eff} of 1.0718 for a 24% of bank D inserted case and K{sub eff} of 0.8512 for the full rodded case. The normalized core power density distributions were obtained and compared with the corresponding FSAR case. (author)

  4. Transition core DNBR penalty determination for Angra-1 nuclear power plant mixed cores consisting of standard and advanced fuel assemblies

    International Nuclear Information System (INIS)

    When two (or more) types of Fuel Assemblies (FA) are inserted in a nuclear reactor core, a flow redistribution occurs, due to the different hydraulic resistances of these assemblies. This way, the FA's with higher hydraulic resistance will get a Departure from Nucleate Boiling Ratio (DNBR) penalty since a part of the total flow will diverge to the FA's with lower hydraulic resistance. Regarding Angra-1 Nuclear Power Plant (NPP), it is planned in a next cycle to insert a new Advanced FA that is a result from a joint-venture project of the companies INB - Industrias Nucleares do Brasil, WEC - Westinghouse Electric Company and KNF - Korean Nuclear Fuel. Therefore, the purpose of this article is to show the work done to determine the DNBR penalty to be applied to the Advanced FA's present in a mixed (or transition) core consisting of Advanced and Standard FA's.

  7. Simulation of the first step of the coupling of the PARCS/RELAP5 codes to ANGRA 2 facility

    International Nuclear Information System (INIS)

    Since the Three Mile Island (1979) and Chernobyl (1986) accidents, the International Agency of Energy Atomic (IAEA) has worked with the authorities of other countries that use nuclear power plants in order to guarantee the safe of those facilities. The utilities have simulated design basic accidents to verify the integrity of the nuclear power plant to these events. However, after Fukushima accident in Japan (2011), the people have felt insecure and been afraid in relation to nuclear power plants. Today, the international and national organizations, such as the International Agency of Energy Atomic (IAEA) and Comissao Nacional de Energia Nuclear (CNEN), respectively, have worked very hard to prevent some accidents and transients in nuclear power plants in order to ensure the security of the general population. In case of accidents, as the Rod Ejection Accident (REA), it is very important to do the coupling between neutronic and thermal hydraulic areas of nuclear reactors. To solve this type of problem there is the coupling between PARCS/RELAP5 codes. However, to perform this analysis it is necessary to simulate three steps. The first step is simulating the steady state of one nuclear power plant by using RELAP5 code. The second step is to run the steady state of this reactor using the coupling PARCS/RELAP5, and the final step is simulating the REA of this facility with PARCS/RELAP5 coupling. The aim of this work is to show the results of the first step of this analysis, i.e., by means of simulation the steady state of Angra 2 nuclear power plant using RELAP5 version 3.3. In this case, the modeling from the core was more detailed than in the original version developed some years ago for Angra 2. The results obtained in this work were satisfactory. (author)

    Full Text Available The role of cortisol on the osmoregulation of pejerrey Odontesthes bonariensis at different salinities was investigated in adult fish injected with 0.7mg hydrocortisone per 100g body weight of fish, and transferred to 0, 5 and 20ppt of NaCl. Blood cortisol was 566ng/ml at the beginning of the experiment (0h but surged to 1250ng/ml within 3h in cortisol-injected fish. Cortisol levels were influenced not only by treatment but also by time, being higher at 3h compared to 24h. Salinity level, time of exposure and their interaction, but not cortisol treatment, significantly affected plasma osmolality and the concentration of ions Cl- and Na+. This study showed that exogenous cortisol does not seem to play a significant role on the regulation of plasma osmolality and concentration of individual ions in pejerrey.Investigou-se a participação do cortisol na osmoregulação de peixe-rei Odontesthes bonariensis, em diferentes salinidades, em peixes adultos injetados com 0,7mg hidrocortisona por 100g de peso corporal, e transferidos para 0, 5 e 20ppt de NaCl. No inicio do experimento (0h, o cortisol encontrado no plasma foi de 566ng/ml, aumentando para 1250ng/ml em 3h em peixes injetados com cortisol. A concentração de cortisol foi influenciada não somente pelo tratamento, mas também pelo tempo, sendo maior 3h após a inoculação, comparada à 24h. A salinidade, o tempo de exposição e a interação desses dois fatores, mas não o tratamento com o cortisol, afetaram significativamente a osmolaridade e a concentração dos íons Cl- e Na+ do plasma. Este estudo mostrou que, o cortisol exógeno não influi significativamente na regulação da osmolaridade e da concentração de íons Na+ e Cl- no plasma em peixe-rei.

  11. Expertise and participation of the population in the context of nuclear risk: democracy and environmental licensing of Angra 3 nuclear power plant

    Directory of Open Access Journals (Sweden)

    Gláucia Silva

    2010-01-01

    Full Text Available This article discusses the specificity of citizens' "participation" in contexts of decision-making on the acceptance of nuclear risk, demonstrating that such acceptance depends on mediation by professionals who are willing to translate the typical scientific jargon of technical reports and/or produce their own reports, by way of counter-expertise; otherwise, lay people are unable to confer scientific legitimacy to their arguments. The basic empirical references for the current analysis are the recurrent themes from public hearings organized for the licensing of two Brazilian nuclear power plants using German technology, Angra 2 and Angra 3, with emphasis on the latter, now undergoing prior environmental licensing. The forms of "social control" engendered in France serve as a counterpoint for developing the article's argument.

  12. Evaluation of tests for coastdown of reactor coolant flow and measure of primary circuit flow of Angra-1 nuclear power plant

    International Nuclear Information System (INIS)

    The Angra 1 Nuclear Power Plant first reload license was issued after several technical discussions among CNEN, FURNAS and KWU. During the license process CNEN has established that the plant could return to anormal operation if the requirements described in the letter CNEN-DExL-C 06/86 were satisfied. The requirements according to the CNEN Transient and Thermohydraulic Group Analysis were to do again the following tests: 'Primary Flow Measurement' to check if the excess flow measured in the first cycle was held; and Pump Coastdown' to check if the Westinghouse and KWU fuel elements are thermo-hydraulicaly compatibles during transients. The mixed core must keep at least the same safety margin presented on Angra 1 FSAR for the original core. The tests and the analysis of results are described. (Author)

    The computational advances observed in the last two decades have been provided direct impact on the researches related to nuclear simulations, which use several types of computer codes, including coupled between them, allowing representing with very accuracy the behavior of nuclear plants. Studies of complex scenarios in nuclear reactors have been improved by the use of thermal-hydraulic (TH) and neutron kinetics (NK) coupled codes. This technique consists in incorporating three-dimensional (3D) neutron modeling of the reactor core into codes, mainly to simulate transients that involve asymmetric core spatial power distributions and strong feedback effects between neutronics and reactor thermal-hydraulics. Therefore, this work presents preliminary results of TH RELAP5 and the NK PARCS calculations applied to model of the Angra 2 reactor. The WIMSD-5B code has been used to generate the macroscopic cross sections used in the NK code. The results obtained are satisfactory and represent important part of the development of this methodology. The next step is to couple the codes. (author)

  18. Brazil: National approach to ageing management

    International Nuclear Information System (INIS)

    Eletrobras Eletronuclear, the Brazilian company responsible for the construction and operation of nuclear power plants, operates two PWR units at Central Nuclear Almirante Álvaro Alberto – CNAAA, situated in Angra dos Reis city. Angra 1 is a 640 MWe Westinghouse plant, operating since 1985, and Angra 2 is a 1350 MWe plant, designed by Areva-Siemens-KWU which started operation in 2001. A third unit, similar to Angra 2, is being constructed at the same site and is due to commence operation in 2016. Angra 1 and 2 nuclear steam supply systems have been designed to ASME and KTA codes, respectively. Brazilian nuclear power plants are licensed for a period of 40 years in accordance with the rule CNEN NE-1.04, ‘Licensing of Nuclear Installations’, issued by, the Brazilian regulatory board: Comissão Nacional de Energia Nuclear (CNEN). PSRs are conducted in accordance with CNEN NE-1.26, ‘Safety in Operating Nuclear Power Plants’, consistent with IAEA Safety Guide No. NS-G-2.10, ‘Periodic Safety Review of Nuclear Power Plants’. A comprehensive AMP at Angra NPP is being developed with the objective of coordinating operations, maintenance and engineering actions to control under acceptable limits the effects of ageing to maintain integrity and functional capability of SSCs important to safety the way that the licensing basis of the plants are maintained during the period of the current operating license and during the period of LTO, as defined in IAEA Safety Reports Series No.57, ‘Safe Long Term Operation of Nuclear Power Plants’. The AMP implementation project at Angra counts on the technical support of the designers of both plants. During the initial phase, technical visits of Westinghouse and Areva and the development of a pilot project for a mechanical system (by Westinghouse) contributed to the first assessments of the available documental infrastructure and of the proposed methodology for the development of AMP processes

    The organometallic and coordination chemistry of rhenium(i) has been largely restricted to bidentate α-diimine ligation and facial tricarbonyl coordination geometries. The thermal transformation of bidentate bis(imino)pyridine and bidentate terpyridine complexes at 200-240 °C under nitrogen led to a family of Re(i) pincer complexes [κ(3)-2,6-{ArN[double bond, length as m-dash]CMe}2(NC5H3)]Re(CO)2X (Ar[double bond, length as m-dash]C6H5, Me2C6H3, (i)Pr2C6H3; X = Cl, Br) and (κ(3)-terpy)Re(CO)2X (X = Cl, Br). The synthesis, single crystal X-ray structural and spectroscopic characterization of these eight species documents their Re coordination geometries and demonstrates the accessibility of such compounds. The basic photophysical features of these compounds show significant elaboration in both number and intensity of the d-π* transitions observed in the UV-vis spectra relative to the bidentate starting materials and these spectra were analyzed using time-dependent DFT computations.

    In this paper a systemic or national approach to cost-effectiveness analysis of risk-reduction measures is reviewed, and its advantages and limitations are discussed. The method is applied to the problem of the cost-effectiveness of increasing the Angra 3 NPP containment wall thickness from the present 60 cm to 180 cm thick in order to prevent damage to the reactor core in case of a direct commercial aircraft crash on it. It is concluded that this measure is not cost-effective if the referred approach is considered. PMID:3120260

    In this work we report numerical simulations using the GILTT (Generalized Integral Laplace Transform Technique) approach to simulate radioactive pollutant dispersion in the Planetary Boundary Layer (PBL). To study the dispersion and the possible scenarios arising from accidental emissions, the results obtained with the GILTT method are compared with experimental data obtained at the Nuclear Power Plant of Angra dos Reis under neutral/moderately unstable conditions. Furthermore, to a better description of the wind profile for the irregular ground level terrain, we consider the wind profile as solution of the MM5 mesoscale model. The statistical indices point out a reasonable good agreement is obtained between experimental data and GILTT model. (author)

  11. Simulation with RELAP5/MOD3.3 of a postulated 10% hot leg break in Angra 2 nuclear power plant

    International Nuclear Information System (INIS)

    This paper presents the simulation results of a 10% break in the hot leg of Angra 2 nuclear power plant, which was run with the computer code RELAP5/MOD3.3. The initial steady state conditions for this simulation are in agreement with the experiment named SB-HL-02 that was conducted in the Large Scale Test Facility in the Rig of Safety Assessment-IV program (ROSA-IV/LSTF). The main boundary conditions specified for the simulation were: high pressure injection system (HPI) and auxiliary feedwater system (AFW) were assumed to be unavailable; and loss of offsite power was assumed to occur concurrently with scram. The results obtained were scaled down and compared with the ROSA-IV/LSTF test, which was performed with the same boundary conditions. This activity was executed in the scope of IAEA research project (CRP J72005) - Evaluation of Uncertainties in the Simulation of Accidents in Angra 2 using RELAP5/MOD3.3 Code Applying CIAU Methodology.

    Full Text Available Dans cet article, on discute la spécificité de la "participation" des citoyens dans les cas de délibération sur l'acceptation du risque nucléaire, montrant que cette participation dépend de la médiation d'un professionnel capable de traduire le jargon scientifique des documents techniques ou établissant lui-même ses propres documents, à titre de contre-expertise; sinon, les profanes ne sauront légitimer leurs arguments scientifiquement. Dans ce travail, on prend comme base empirique les thèmes récurrents des audiences publiques organisées en vue du permis de fonctionnement des deux centrales nucléaires brésiliennes de technologie allemande - Angra 2 et Angra 3 -, surtout pour cette dernière, en cours de licence environnementale préalable. Les formes de "contrôle social" patriquées en France servent de contrepoint à la construction de ce qui est ici exposé.

  13. Analysis of the loss of coolant accident due to the faiture in the open position of two pressurizer relief valves, for Angra-1 nuclear power plant

    International Nuclear Information System (INIS)

    A study of the modeling techniques adequate for simulating the loss of coolant accident caused by stuck open pressurizer relief valves, using the RELAP4-MOD5 code, is performed and the model developed is applied to the analysis of this kind of accident for the Central Nuclear Almirante Alvaro Alberto Unit (Angra 1). The thermal hydraulic behavior of the reactor cooling system, when subjected to a loss of main feedwater followed by the failure in the open position of two pressurizer relief valves, is determined. The relief valves are assumed to fail in the totally open position, delivering the maximum massflow through the discharge line. The RELAP4-MOD5 code is shown to be adequate for this kind of analysis, and the detailed prediction of the thermal hydraulic behavior of the Reactor Coolant System is thus possible. The eficiency of the emergency core cooling system of Angra 1 is demonstrated, the fuel elements remaining covered by the coolant during all the accident, and the peak clad temperatures are kept within design limites, ensuring the integrity of the core.

    Full Text Available Para avaliar o efeito da suplementação de metionina e lisina sobre o desempenho de alevinos de peixe-rei (Odontesthes bonariensis, estabeleceu-se um experimento completamente casualizado com quatro tratamentos. A dieta T1 (controle continha as concentrações de metionina e lisina disponíveis nos produtos usados na formulação da mesma. A dieta T2 foi suplementada com 4,76% de DL-metionina; a dieta T3, com 4,76% de L-lisina; e a dieta T4, com 4,54% de DL-metionina e 4,54% de L-lisina. As dietas suplementadas com metionina foram mais eficientes que a dieta-controle e a suplementada apenas com lisina, pois esta não apresentou diferença em relação à dieta-controle, comprovando que a quantidade de lisina disponível nos produtos utilizados na elaboração das dietas atende às necessidades dos alevinos de peixe-rei. A quantidade de metionina disponível nestas formulações é insuficiente para o bom desempenho dos alevinos, devendo ser suplementada.A completely randomized experiment was run to evaluate the effect of methionine and lysine supplementation on the pejerrey (Odontesthes bonariensis fingerlings performance. Four treatments were compared: Diet T1 control, with available contents mehionine and lysine in products used in formulation of diets; Diet T2 supplemented with 4.76% of DL- methionine; Diet T3 supplemented with 4.76% of L- lysine and Diet T4 with 4.54% of DL methionine and 4.54% of L lysine. Resulted showed that diets containing methionine were more efficient than control diet and diet with lysine only. Control diet did not differ from diet with lysine supplementation only. It is shown that contents of available lysine in products used in the formulation of diets meet pejerrey fingerlings requirements. Amounts of methionine in control diet are insufficient for fingerlings growth. A supplementation of this aminoacid is required to maximize performance.

  18. The utilization of geochemical parameters for the environmental monitoring of the Nuclear Power Center of Angra I, Ribeira Bay, Rio de Janeiro, Brazil

    International Nuclear Information System (INIS)

    In order that a geochemical balance be as complete as possible and thus, reach predictive values for toxic chemical dispersion, an understanding of the hydrological, sedimentological and geological contexts is fundamental. The dispersion of a polluent (in this case radionuclides) is dependent, in part, on its chemical properties and its interaction by sorption and desorption from solid particles (in particular, sediments). This interaction needs to be incorporated in dispersion models and can influence the passage of a pollutant along the food chain. In the case of Ribeira Bay, near the nuclear power center of Angra I, it was observed, through the analysis of sedimentological and geochemical parameters (TOC, TSS, chemical and mineralogical compositions, and granularity): an increase in absorption capacity of surface sediments owing to a homogeneous grain size distribution and a varying clay composition; a possibility of remobilization and transfer of particulate material to areas outside the bay.

  19. Comparative studies of the pressure - and temperature temporal behavior in the Angra I containment when submitted to the design basic accident

    International Nuclear Information System (INIS)

    A computer code - CONDRU 4 - was brought from Germany, that is being used for the determination of pressure - and temperature temporal behavior that occurs inside the metallic containment of PWR type reactors before the loss of coolant accident (LOCA). Simulation for Angra-1 reactor was made, considering the ocurrence of the worst postulated accident for the containment integrity. The results obtained with CONDRU 4 computer code were compared with those obtained by the CONTEMPT-LT-and COCO computer code for the same nuclear power plant. The discrepancy found among the results were due mainly to the different modes adopted in the several codes for the steam-water separation of coolant injected in the containment. (Author)

  20. A model for reliability avaliation of the electrical supply source of the 1A3 and 1A4 control rods assemblies of Angra I reactor

    International Nuclear Information System (INIS)

    The reliability of the electrical power supply to the 4.16KV buses for the safety system operation of a nuclear power plant was studied. Particularly, Angra Unit I system was focused. Initially, reliability of each electrical supply source was estimated. Using a probabilistic approach based on the Markov processes, the system reliability was evaluated in terms of frequency and duration of loss of power supply and of the system failure probability evolution when one or more sources remained unavailable. Based on these results, certain reactor operating rules were proposed concerning later shutdown of the plant without compromising the nuclear reactor safety. A sensitivity analysis was also performed to show the different reliability parameter influences on final results. This analysis showed that the diesel system performs an important role in the power supply for a nuclear power plant

  1. Reliability study of the Angra-I component coolant system considering uncertainty in the fault tree analysis by a fuzzy model

    International Nuclear Information System (INIS)

    The probabilistic safety analysis (PSA) has been used in industrial plant risk studies since 1960. In nuclear regulatory and the PSA are a non-dispensable methodology. The estimation of the system top event using fault tree/minimal cut set approach is the higher traditional PSA technique applied. However, the credible results is strongly linked to basic event precision. Recently, some researchers have developed mathematical approaches to estimate the dispersion in failure data. The fuzzy set theory is a good option to be applied in order to characterize the derivation of a basic event. This paper presented the bases of a fuzzy methodology commonly applied in fault tree studies, and, finally, it showed a realistic case study involving Angra I component coolant system. (author)

  4. From DOS to UNIX

    International Nuclear Information System (INIS)

    Union Pacific Resources (UPRC) is a large independent operator with about 100 petroleum engineers. UPRC has a reasonably sophisticated PC network with many hundreds of PC's connected via several local area network (LAN) servers. Essentially all engineers have a 386 based PC on their desk with access to a host of software packages, peripheral devices and to mainframe computers. Many engineers are now acquiring 486 based PC's. UPRC's solution has involved migrating from a DOS-based platform on individual user's desk to UNIX workstations. Dozens of UNIX workstations are networked; some are on the desk, while others are located in central locations. Reservoir simulation, geostatistical modeling, image processing and log analysis are now done exclusively on the UNIX workstations. Numerous DOS-based programs, however, have not yet been migrated into the UNIX environment. This paper describes the topography of both PC DOS and UNIX workstation networks in UPRC, and examine the flow of information in each network configuration to identify differences. The successes and failures of various techniques for providing access to both platforms will be presented

  10. Geochronology of anthropogenic radionuclides in Ribeira Bay sediments, Rio de Janeiro, Brazil

    International Nuclear Information System (INIS)

    Ribeira Bay is located approximately 130 km south of the city of Rio de Janeiro and receives discharges of liquid effluent from the Angra dos Reis nuclear power plant (NPP) site, where two pressurized water reactors are located. To test whether the presence of anthropogenic radionuclides in sediments in Ribeira Bay could be correlated to the NPP operations, we sampled seven sediment cores and determined accumulation rates and chronologies. Only one sediment core did not exhibit a superficial mixing layer; this sample was used for dating purposes. Cesium-137 and 207Bi were observed in this sediment profile, but their presence was associated with atmospheric fall-out rather than the nearby NPP. The exponential decay of 210Pb concentration with sediment layer depth was verified below a superficial mixing layer for all other sediment cores. Calculated accumulation rates ranged from 1.2 mm y-1 in the inner bay to 6.2 mm y-1 close to its entrance. - Graphical abstract: Display Omitted Highlights: → We have dated seven sediment cores on the region close to the Angra dos Reis nuclear power plant site. → Cs-137 and Bi-207 were detected and were used as a tool to validate the Pb-210 dating results. → The spatial variation of the Pb-210 flux indicates two main sources of sediments: the channel between Ilha Grande (Grande Island), and the continental and soil runoff from the adjacent hills.

  13. Transit and absorption of nuclear industry derivatives by marine biota

    International Nuclear Information System (INIS)

    A broard research program on radionuclides became necessary due to the construction of the Nuclear Power Plant at Angra dos Reis. As part of this program the research developped by the Marine Biology Departament, UFRJ, aimed at estimating the radiation doses to wich the population of the region might be exposed and to determine biological indicators to radioactive contamination. Up to the present moment, the bioacumulation factors (BFs) of 60Co, 137Cs and 131I by ''clam'' (Anomalocardia brasiliana) and the biological half-life of cobalt and cesium in this animal were determined, as well as the B.F. of 85Sr by ''snail'' (Strombus pugilis) and by ''barnacle'' (Megabalanus tintinnabulum). The remobilization of 60Co by microbiological activity in marine sediment was also studied. These studies were made using the standard methodology for bioaccumulation and elimination in closed water systems. The results showed an important microbiological activity in the remobilization of elements in the sediment. Due to the low bioaccumulation factors obtained the studied organisms were not considered ideal biological indicators for radioactive pollution. However, their importance as edible animals in the Angra dos Reis region recommends their radiometry for routine radiological monitoring. Studies on other organisms and/or radionuclides are now in progress at the Marine Biology Departament (UFRJ). (author)

  14. Acoustoelastic evaluation of the 20 MnMoNi 55 structural material of the pressure vessels of Angra 2 and 3 nuclear reactors

    International Nuclear Information System (INIS)

    The pressure vessels of the Angra II and Angra III nuclear power plants, which are of large thickness, have as one of their structural components the 20 MnMo Ni 55 steel. The acoustoelastic evaluation carried out through non-destructive ultrasonic tests was based on the variation of the speed of ultrasonic shear waves of normal incidence as a function of the stress applied in the material using the acoustic birefringence technique, which considers the fractional difference of the speeds of two ultrasonic waves propagating in orthogonal directions. In this work two experiments were carried out. In the first one, a new method for acquisition of ultrasonic signals for joint application with this technique of stress analysis was evaluated by comparison with the conventional one. The aim was to determine its potential and limitations for application in materials up to 120 mm of thickness. In the second experiment, the acoustoelastic behavior of the 20 MnMo Ni 55 steel was studied. The new method of acquiring ultrasonic signals led to satisfactory results and was used in the study of the acoustoelastic behavior of the 20 MnMoNi 55 steel. The acoustoelastic analysis indicated that the material has an anisotropic and heterogeneous behavior. The acoustoelastic constant of this material, obtained experimentally from the analysis of the graphs of the material behavior (birefringence x stress) under compression tests performed on specimens of the 20 MnMo Ni 55 steel, was used for the quantitative stress analysis. A specimen of the 20 MnMo Ni 55 steel was subjected to a bending test to carry out a qualitative stress analysis through the difference between the values of the birefringence obtained during loading (B) and before loading (Bo) in every point studied. With the obtained results it was possible to identify qualitative and quantitatively the regions of the specimen under compressive and tensile stresses. The execution of these tests allowed to verify the efficiency of

The Uncertainty Methodology based on Accuracy Extrapolation (UMAE) is used to characterize the uncertainty in the prediction of system code calculations for light water reactors and is internally coupled with the above system code. Following an overview of the CIAU development, the present paper deals with the independent qualification of the tool. The qualification test is performed by estimating the uncertainty bands that should envelope the prediction of the Angra 1 NPP transient RES-11. 99 originated by an inadvertent complete load rejection that caused the reactor scram when the unit was operating at 99% of nominal power. The current limitation of the 'error' database, implemented into the CIAU prevented a final demonstration of the qualification. However, all the steps for the qualification process are demonstrated.

    The aim of this study was to assess the regional impacts of heavy metals (Mn, Fe, Mg, Ca, Cu, Zn, Cd, Cr, Pb and Ni) on water, sediment and a native, teleost fish species, Labeo angra, inhabiting a flood plain wetland of Barak River in Assam, India. Heavy metal concentrations in the water, sediments and fish were measured; bioaccumulation factor, metal pollution index as well as condition indices were calculated, to assess the pollution load and health status of the fish. Multivariate statistical analysis was used on wetland water and sediment heavy metals to ascertain the possible sources and seasonal variations of the pollutants. Results showed that most heavy metals in the wetland water and sediments exceeded the water (drinking and irrigation) and sediment quality guidelines, respectively. Seasonal variations were observed for geogenic heavy metals, Mn, Fe, Mg and Ca while no seasonal variations were observed for anthropogenic heavy metals, Cu, Cd, Cr, Pb and Ni. Multivariate statistical analysis showed that there was strong correlation between geogenic and anthropogenic heavy metals in water and sediment, both originating from the common anthropogenic sources. Accumulation of most of the metals in all the tissues was above the safe limits as recommended by the Food and Agriculture Organization. High bioaccumulation factors and metal pollution index for these metals in the different tissues revealed that metals were extensively bio-accumulated and bioconcentrated. Condition indices in fish from the wetland suggested metabolic abnormalities. PMID:26422176

  19. Development of a suitable weld geometry for pressure resistance welding of the leader test assembly (LTA's) 16NGF fuel assembly fuel rod at Angra-1 Nuclear Power Plant

    International Nuclear Information System (INIS)

    The purpose of this work is to develop suitable weld geometry for pressure resistance welding of the zircaloy-4 end plug to the special zirconium alloy cladding tube, Ø 9,14mm, for demonstration at Angra-1 Nuclear Plant. Weld geometry development was carried out in two steps: at the first one, the influence caused by the variation of the welding process key parameters, the axial compression strength of the end plug against the cladding tube, projection of the cladding tube into the welding chamber and the welding current have been evaluated; at the second step, the influence of the variation of end-plug weld geometry area was checked. For the combination of welding parameters, the technique of factorial design was used. Results from mechanical and metallographic tests have indicated a strong and direct influence of weld geometry dimensional variation on the weld mechanical resistance, and a modest influence in relation to the range of key parameters used to carry out tests.

    Full Text Available The troglobitic armored catfish, Ancistrus cryptophthalmus (Loricariidae, Ancistrinae is known from four caves in the São Domingos karst area, upper rio Tocantins basin, Central Brazil. These populations differ in general body shape and degree of reduction of eyes and of pigmentation. The small Passa Três population (around 1,000 individuals presents the most reduced eyes, which are not externally visible in adults. A small group of Passa Três catfish, one male and three females, reproduced spontaneously thrice in laboratory, at the end of summertime in 2000, 2003 and 2004. Herein we describe the reproductive behavior during the 2003 event, as well as the early development of the 2003 and 2004 offsprings, with focus on body growth and ontogenetic regression of eyes. The parental care by the male, which includes defense of the rock shelter where the egg clutch is laid, cleaning and oxygenation of eggs, is typical of many loricariids. On the other hand, the slow development, including delayed eye degeneration, low body growth rates and high estimated longevity (15 years or more are characteristic of precocial, or K-selected, life cycles. In the absence of comparable data for close epigean relatives (Ancistrus spp., it is not possible to establish whether these features are an autapomorphic specialization of the troglobitic A. cryptophthalmus or a plesiomorphic trait already present in the epigean ancestor, possibly favoring the adoption of the life in the food-poor cave environment. We briefly discuss the current hypotheses on eye regression in troglobitic vertebrates.O cascudo troglóbio (exclusivamente subterrâneo, Ancistrus cryptophthalmus (Loricariidae, Ancistrinae é conhecido de quatro cavernas na área cárstica de São Domingos, bacia do alto rio Tocantins, Goiás.

Os autores partem da premissa de que foliões, festeiros e devotos são, na feliz expressão de Carlos Rodrigues Brandão, "especialistas" do saber da devoção, por sentirem-se incumbidos de representar a Igreja em cada uma da partes que compõem a Folia, desde a saída do Terno até chegar o dia da festa de Santos Reis. O texto procura mesclar reflexão teórica conceitual sobre a festa com os métodos de pesquisa da História Oral, a partir da observação in loco. Conclui com a constatação de que esta importante tradição popular mantem-se ainda muito viva e forte, não apenas na comunidade em foco, mas ainda na região do Triângulo Mineiro.

João I, escrita por Fernão Lopes após a morte desse monarca, com o objetivo de legitimar o seu poder e o de sua descendência, também se constitui em manual educativo, pois propõe modelos ideais de comportamento da nobreza e da monarquia.

    It was postulated, in the cooling system of the core, a LOCA, where 431 m3 of soda almost instantaneously was lost. This inventory contained 1.87x1010 Bq/m3 of tritium, 2.22x107 Bq/m3 of cobalt,3.48x108 Bq/m3 of cesium and 3.44x1010 Bq/m3 of iodine and was released in liquid form near the Itaorna cove, Angra dos Reis - RJ. Applying the model in the proposed scenario (Angra 1 and 2 in operation and Angra 3 progressively reducing the capture and discharge after the accident), the simulated dilution of the specific activity of radionuclide spots, reached values much lower than report levels for seawater (1,1x106 Bq/m3, 1,11x104 Bq/m3 and 1,85x103 Bq/m3) after 22 hours, respectively for 3H, 60Co, 131I and 137Cs. From the standpoint of public exposure to radionuclide dispersion, the results of activity concentration obtained by the model suggest that the observed radiological impact is negligible. Based on these findings, we conclude that there would be no radiological impact related to a further release of controlled effluent discharges into Itaorna cove. (author)

Este trabalho buscou estudar três proporções entre a linhagem macho-estéril (linhagem A e a mantenedora (linhagem B. As proporções estudadas foram 8:4, 10:2 e 14:4. As características avaliadas para determinar qual das proporções apresenta maior potencial foram: número e porcentagem de grãos cheios por panículas, e número de grãos de pólen por unidade de área. A proporção 8:4 produziu maior porcentagem de grãos cheios por panícula que as outras duas, mas, proporcionalmente, ocupa maior área física com a linhagem B no campo. Foram observadas diferenças estatísticas na porcentagem de grãos cheios entre as amostras coletadas nas várias fileiras da linhagem A (diferentes distâncias da fonte polinizadora, e observou-se uma influência marcante com relação à direção predominante dos ventos. O número de grãos de pólen foi igual para todas as relações e distâncias da fonte de pólen; por isso, não foi o fator determinante das diferenças observadas em porcentagem de grãos cheios por panícula. Os resultados permitiram concluir que a proporção 10:2 é a de maior potencial para a produção comercial de sementes da linhagem macho-estéril.Commercial male-sterile rice (Oryza sativa L. seed production is one of the limitations to allow large scale hybrid seed production.

  10. National approach to economic performance indicators for nuclear power plants: Brazil

    International Nuclear Information System (INIS)

    The Brazilian electrical system comprises a fairly large grid, covering a very large territory, with a current installed capacity of around 75 GW. The electricity generated is predominantly hydroelectric. There has been great pressure in the last years to aggregate new energy to the grid in order to meet an increase in demand, thus requiring heavy investment in the generation, transmission and distribution of electricity. Under these circumstances it will be possible for nuclear power to participate in this market and to overcome the main obstacles to its growth in the electrical matrix. There are two nuclear units in operation: Angra 1 (657 MW(e) PWR) which went into commercial operation in January 1985 and Angra 2 (1350 MW(e) PWR) which started commercial operation in February 2001. Both are located in the Angra dos Reis region, 130 km from Rio de Janeiro and 220 km from Sao Paulo. A third PWR plant, Angra 3, similar to the second unit, is under construction at the same site. Although the capacity of the two nuclear plants represents less than 3% of the total installed capacity in Brazil, they produced, in 2002, close to 14,000 GW·h, corresponding to 4% of the total national electricity production and approximately 12% of the maximum storage capacity of the equivalent water reservoir in the southeast and central-west regions. The current challenge for nuclear energy in Brazil is to compete in the new market, in which the tariffs of the four federal supplier companies in 2002 stayed around 20 $/MW·h for the generation services. The generation costs of hydroelectric plants are currently about 15 $/MW·h compared with nuclear's 27 $/MW·h. It is a question of competitiveness. In the long term, nuclear energy will be necessary in the Brazilian energy mix. It is not known how long this period will be or whether Brazil will be able to implement its nuclear power programme in the future

    Full Text Available Este artigo pretende apresentar a psicopatologia dos atos a partir do esquema de Jacques Lacan sobre a angústia. Diferenciamos os acting-out, a passagem ao ato, os sintomas, as inibições e a angústia fazendo uma duplicação do esquema de Lacan levando em consideração os registros do simbólico, do real e do imaginário. Esse esquema permite uma abordagem da questão dos atos do sujeito sem cair em uma perplexidade do clínico, nem na confusão entre os atos e a ação. Permite também uma melhor orientação do clínico em relação às diversas modalidades de respostas subjetivas que não se restringem à questão sintomática, que é o campo inaugural da clínica psicanalítica desde a sua fundação por Sigmund Freud. Acreditamos contribuir, assim, para um maior esclarecimento desse esquema no ensino de Lacan e para que ele possa servir de orientação para o tratamento dos atos do sujeito na clínica.

    This work develops two models of signal validation in which the analytical redundancy of the monitored signals from an industrial plant is made by neural networks. In one model the analytical redundancy is made by only one neural network while in the other it is done by several neural networks, each one working in a specific part of the entire operation region of the plant. Four cluster techniques were tested to separate the entire region of operation in several specific regions. An additional information of systems' reliability is supplied by a fuzzy inference system. The models were implemented in C language and tested with signals acquired from Angra I nuclear power plant, from its start to 100% of power. (author)

    The photochemistry and photophysics of the cationic molecular dyad, 5-{4-[rhenium(I)tricarbonylpicoline-4-methyl-2,2'-bipyridine-4'-carboxyamidyl]phenyl}-10,15,20-triphenylporphyrinatopalladium(II) ([Re(CO)(3)(Pic)Bpy-PdTPP][PF(6)]) have been investigated. The single crystal X-ray structure for the thiocyanate analogue, [Re(CO)(3)(NCS)Bpy-PdTPP], exhibits torsion angles of 69.1(9)°, 178.1(7)°, and 156.8(9)° between porphyrin plane, porphyrin-linked C(6)H(4) group, amide moiety, and Bpy, respectively. Steady-state photoexcitation (λ(ex) = 520 nm) of [Re(CO)(3)(Pic)Bpy-PdTPP][PF(6)] in dimethylformamide (DMF) results in substitution of Pic by bromide at the Re(I)Bpy core. When [Re(CO)(3)(Pic)Bpy-PdTPP][PF(6)] is employed as a photocatalyst for the reduction of CO(2) to CO in DMF/NEt(3) solution with λ(ex) > 420 nm, 2 turnovers (TNs) CO are formed after 4 h. If instead, a two-component mixture of PdTPP sensitizer and mononuclear [Re(CO)(3)(Pic)Bpy][PF(6)] catalyst is used, 3 TNs CO are formed. In each experiment however, CO only forms after a slight induction period and during the concurrent photoreduction of the sensitizer to a Pd(II) chlorin species. Palladium(II) meso-tetraphenylchlorin, the hydrogenated porphyrin analogue of PdTPP, has been synthesized independently and can be substituted for PdTPP in the two-component system with [Re(CO)(3)(Pic)Bpy][PF(6)], forming 9 TNs CO. An intramolecular electron transfer process for the dyad is supported by cyclic voltammetry and steady-state emission studies, from which the free energy change was calculated to be ΔG(ox)* = -0.08 eV. Electron transfer from Pd(II) porphyrin to Re(I) tricarbonyl bipyridine in [Re(CO)(3)(Pic)Bpy-PdTPP][PF(6)] was monitored using time-resolved infrared (TRIR) spectroscopy in the ν(CO) region on several time scales with excitation at 532 nm. Spectra were recorded in CH(2)Cl(2) with and without NEt(3). Picosecond TRIR spectroscopy shows rapid growth of bands assigned to the π-π* excited

    The PETROBRAS produced water programme, conducted by PETROBRAS S.A. is the response to the challenge faced in handling, treating and discharging produced water associated to oil production that comes from Campos Basin mainly. After run modeling studies in oil and produced water associated through 2015 scenario, it was identified the total amount of produced water that will be handle monthly, increasing from 215.000 m{sup 3} up to 420.000 m{sup 3}. To achieve the goals of treating e discharging that huge amount of water, the program understood the following main actions: built 5 produced water plants (Sao Sebastiao, Macae-Cabiunas, Angra dos Reis, Sao Francisco do Sul and Osorio) and 2 reinjection sites (Cabiunas and Lagoa Parda). These plants and sites will be able to treat monthly the total produced water amount of 677.000 m{sup 3}. (author)

  19. Uranium and thorium in achondrites.

    The abundances of U and Th in 19 achondrites and two pallasite olivines have been measured by radiochemical neutron activation analysis. Brecciated eucrites are enriched relative to chondrites in both elements by factors between 10 and 20, perhaps as a result of a magmatic differentiation process. Two unbrecciated eucrites are far less enriched, possibly due to their origin as igneous cumulates. The diogenites Johnstown and Shalka contain approximately chondritic levels of U and Th, but Ellemeet is 10 times lower. The abundances in three howardites are in good agreement with those expected from major element data for a mixing model with eucrite and diogenite end members. The high O-18 basaltic achondrites Nakhla, Shergotty and Angra dos Reis have a range of U and Th abundances similar to the brecciated eucrites and howardites, but have systematically higher Th/U ratios.

O que se está procurando compreender é de que modo as remessas poderiam afetar positiva ou negativamente a economia dos países de origem dos imigrantes. Discutir o papel e o significado das remessas implica, assim, uma discussão em torno da existência (ou não de um "campo de positividades" do fenômeno migratório internacional. O principal objetivo deste artigo é contribuir para essa discussão por meio de um estudo empírico do caso brasileiro que adota as remessas como foco. Para tanto, é identificado o perfil das remessas e dos remetentes, assim como os objetivos e os beneficiários do dinheiro enviado. A pesquisa usa uma abordagem baseada em entrevistas em profundidade e survey não-representativo (Boston e Governador Valadares.DO REMITTANCES contribute to local development and the reduction of poverty? What are the consequences of the dollars sent by the migrants to the people, families, and organizations that receive them in the cities of origin? These are the key questions that recent studies have raised. According to some authors "migration is inevitable and has the potential to be quite positive in terms of development and reduction of poverty. The policies that have their origins in this principle will be more successful than those that attempt to oppose, intransigently, both globalization and the migration of people in space". Do current international migrations produce positive local development effects? The main objective of this article is to contribute to this discussion through an empirical study of the Brazilian case, which takes remittances as its focus. Thus, we identify who the immigrants are who send remittances from the United States to Brazil, to what ends the remittances are directed, who the beneficiaries are, and how the remittances

    Technical support is provided for the operation of an emergency vehicle of Instituto de Radioprotecao e Dosimetria/Comissao Nacional de Energia Nuclear, Rio de Janeiro, Brazil, in the event of uncontrolled release of radioactivity from the Angra Nuclear Power Plant (NPP) to the atmosphere. It is based on internationally adopted emergency decision process philosophy, the concept of 'Protective Action Guide' (PAG), the exposure pathways relevant to nuclear accidents, the measuring systems to be used in obtaining the exposure rate in the effluent 'plume', the methods utilized to predict dose to the population, radioiodine suppression measures, the monitoring instrumentation available to the emergency group, some post-accident considerations and finally, the monitoring that may be carried out from an aircraft. Information is given about the NPP operator's responsabilities with respect to the prediction of the consequences of an accident, as well as methods for thyroid and whole body dose estimation based on exposure to the radioiodine and noble gases present in the effluent plume. The example of the Three Mile Island's incident is used to formulate some observations regarding collective dose to the public estimates derived from measurements made from a helicopter. (Author)

    This study has the aim to assess the impact of accidental release of tritium postulate from a nuclear power reactor through environmental modeling of aquatic resources. In order to do that it was used computational models to simulation of tritium dispersion caused by an accident in a Candu reactor located in the ongoing Angra 3 site. The Candu reactor is one that uses heavy water (D{sub 2}O) as moderator and coolant of the core. It was postulated, then, the LOCA accident (without fusion), where was lost 66 m3 of soda almost instantaneously. This inventory contained 35 P Bq and was released a load of 9.7 TBq/s in liquid form near the Itaorna beach, Angra dos Reis - RJ. The models mentioned above were applied in two scenarios (plant stopped or operating) and showed a tritium plume with specific activities larger than the reference level for seawater (1.1 MBq/m{sup 3}) during the first 14 days after the accident.

    Full Text Available No final dos anos 50 e começo doe anos 60, houve uma reformulação significativa da Matemática no Brasil. Sob a bandeira do modernismo, seus defensores buscaram inovações no ensino da Matemática. Dessa forma, os reformistas se concentraram essencialmente na linguagem abusiva e no formalismo da Teoria dos Conjuntos, o que trouxe mais danos do que benefícios do ensino da Matemática de 1º e 2ºgraus. A linguagem formal da Teoria dos Conjuntos é porém sua parte menos importante. A teoria criada por Cantor tão logo revelou-se como o fundamento de toda a Matemática, possibilitando o desenvolvimento de novas disciplinas, como a Topologia, a Algebra Abstrata, a Teoria da Medida e Integração, a Teoria da Probabilidade e a Análise Funcional. O objetivo deste trabalho é um relato sucinto de como surgiu essa teoria, apresentando o "Conjunto de Cantor" como um dos mais ricos exemplos de "Conjunto perfeito" encontrados na literatura matemática.

Tad akivaizdu, kad XXI a. žmogus vis labiau pasineria į įvairių medijų tinklus, apraizgančius jo gyvenimą ir tampančius pagrindine socialios ir visavertės eg zistencijos sąlyga. Tokios socialinės institucijos, kaip menas, televizija, politika, religija, šeima ir daugelis kitų, nūdien jau nebėra tokios savarankiškos, kaip, tarkime, prieš dešimt, dvidešimt ar daugiau metų. Jų suverenitetą daugiausia transformuoja būtent medijos, šioms institucijoms diktuojančios savas sąlygas ir primetančios savas taisykles. Kitaip tariant, medijos tampa tokios galingos, kad ima steigti savuosius dėsnius, kuriems vis labiau paklūsta tradicinė gyvosios socializacijos aplinka.

Isto abre um precedente para a utilização de produtos não considerados como fontes de micronutrientes na fabricação dos fertilizantes. Todavia, a eficiência agronômica desses produtos é ainda duvidosa. Objetivou-se realizar um trabalho para caracterizar a solubilidade e a disponibilidade dos micronutrientes em trinta fertilizantes comerciais, por meio do uso de cinco extratores químicos: a água e soluções de ácido cítrico a 2%, de citrato neutro de amônio na diluição 1 + 9, de DTPA 0,005 mol L-1 e de EDTA 0,005 mol L-1. Os resultados mostraram a baixa solubilidade dos micronutrientes metálicos (cobre, ferro, manganês e zinco dos fertilizantes tipo "fritas". O ácido cítrico a 2% mostrou-se promissor na caracterização da disponibilidade de cobre, manganês e zinco para as plantas. Para o ferro não houve uma definição entre os extratores estudados. O boro teve boa solubilidade, tanto nos fertilizantes solúveis, como nos insolúveis em água, e a garantia pelo teor total mostrou-se bom indicativo da disponibilidade do elemento. Para o molibdênio a solubilidade foi maior para os fertilizantes com baixo teor do elemento. A garantia dos micronutrientes catiônicos pelo teor total, conforme exige a legislação, não indicou a sua real disponibilidade nos fertilizantes comerciais, mostrando a necessidade de uma definição de extratores para esse fim.

    Full Text Available Listrura costai, new species, is described from small streams in a swampy coastal plain in the rio Jurumirim basin, Angra dos Reis Municipality, Rio de Janeiro State, southeastern Brazil. The new species is morphologically very similar to L. nematopteryx and L. picinguabae, all possessing only one long pectoral-fin ray. It differs from its congeners by possessing an autapomorphic character: first hypobranchial with an anterior process (vs. process absent. Other features such as coloration, numbers of opercular and interopercular odontodes, number of anal-fin rays, head length, and shape of some bone structures help to distinguish the new species from L. nematopteryx and L. picinguabae. Molecular analyses using partial sequences of the mitochondrial DNA genes cytochrome oxidase c subunit 1 and cytochrome b from the new species and morphologically similar species are provided. The results about both molecular markers corroborate the validity of the new species by significant genetic distance values between it and congeneric species, and by its phylogenetic position in the hypotheses performed by maximum-parsimony method.Listrura costai, espécie nova, é descrita de exemplares obtidos em pequenos córregos restritos à bacia do rio Jurumirim, município de Angra dos Reis, estado do Rio de Janeiro, sudeste do Brasil.

Tomando a Declaração Universal dos Direitos do Homem, de 1948, como base e ponto de partida, o articulista aborda as três principais vertentes dos sistemas de promoção desses direitos: a européia, a americana e a africana. A evolução de cada uma delas descrita analógica e epistemologicamente, de forma a salientar singularidades sem perder de vista as influências recíprocas ou mesmo as determinantes próprias do contexto espaço-social. Para finalizar, o articulista destaca a importância do Tribunal Penal Internacional no estabelecimento de uma justiça ecumênica. Concomitantemente, alerta para o perigo contido na ameaça de os EUA não o ratificarem.The text underlines the institutional character acquired by the main systems to promote Human Rights in the twentieth century. Taking the Universal Human Rigths Declaration, of 1948, as the basis for analysis, the author brings up three different approaches to promote these rights: the European, the American and the African. The evolution of each of them is described using its procedure as a basic reference. Besides, an analogical analysis, brings to the fore singularities, without ignoring reciprocal influences dictated by particular contexts, though. The author stresses the importance of the International Penal Court, as a means to establish ecumenical justice. At the same time, he reminds the reader of the risks implicit in the possible non-ratification of the IPC by United States.

  12. As religiões dos brasileiros

    Pierre Sanchis

    2009-05-01

    Full Text Available Há dois movimentos simultâneos no campo religioso brasileiro: um primeiro de distinção, multiplicação e rupturas; um segundo de relativa homogeneização.  No campo cristão, o fenômeno mais visível é o da entrada maciça dos pentecostais, não só na arena religiosa em geral, mas nos seus pontos de alta visibilidade, especialmente populares. O significado da preferência dos pobres e do aparente trânsito do catolicismo ao pentecostalismo tende a representar o trânsito entre duas culturas: a tradicional católica afro-brasileira, e a cultura moderna de escolha individual.  A Nova Era, por exemplo, representa ao mesmo tempo a contudente negação de uma modernidade individualista, racional e dessacralizadora, a tentativa de recapitular, no que tem de global, espiritual, carnal e cósmico, o caminhar do homem para uma completude nunca atingida, porque nunca concluída.  Assim, o meio religioso brasileiro, sobretudo popular, mas não exclusivamente, vive num certo clima espiritualista que parece compartilhado por várias mentalidades no Brasil. Pode-se então levantar a seguinte questão: como escapar, neste nosso olhar sobre as religiões dos brasileiros, de uma visão tão linearmente evolucionista, positivista na sua concepção, repressiva na sua política?

    Full Text Available A partir do anúncio da reedição de seu livro O Mundo dos Bens, publicado originalmente em 1979, a autora faz uma reflexão do contexto intelectual em que sua obra foi fundamentada. Ela discute as bases da importância do estudo do consumo para a economia e para a antropologia, salientando que isso pode contribuir para alcançar o projeto de "totalidade" dos fenômenos sociais, na perspectiva de Marcel Mauss - autor que teve grande influência para O Mundo dos Bens. O artigo ainda mostra trabalhos e debates clássicos sobre o tema das trocas que contribuíram para as reflexões desenvolvidas no livro. É retomado o argumento de que a pobreza deve ser entendida como um processo de exclusão de informação e, nesse sentido, a autora expõe porque o estudo sobre o consumo é de grande valia para a antropologia.Taking into account the announcement of the re-edition of her book The World of Goods, originally published in 1979, the author develops a reflection on the intellectual context in which her work was created. She discusses the bases of the importance of Consumption Studies for Economics and Anthropology, suggesting that they help to attain the project of "totality" in the study of social phenomena, following the notion of Marcel Mauss - an author who exerted a great influence in the The World of Goods. The article also analyses classical works and discussions about exchanges that contributed to the reflections developed in the book. She resumes her central point, that is, that poverty must be understood as a process concerning the exclusion of information. In this sense, she presents the reasons the study on consumption is of great value for Anthropology.

  15. Por uma carta dos bens fundamentais

    Luigi Ferrajoli

    2010-07-01

    Full Text Available Este artigo questiona a possibilidade de a estipulação dos direitos fundamentais, e suas obrigações e proibições correspondentes, ser suficiente para garantir adequadamente as necessidades e os interesses vitais, em especial aqueles de interesse coletivo. São bens fundamentais aqueles cujo acesso é garantido a todos e a cada um, visto que são objetos dos direitos fundamentais subtraídos à lógica do mercado. A garantia de novos bens como bens fundamentais exige uma decisão política civilizatória de submeter ao direito as relações de mercado. Assim, às cartas e convenções internacionais e constitucionais de direitos fundamentais deveriam ser acrescentadas Cartas Constitucionais e Cartas Internacionais de bens fundamentais. Daí a necessidade de uma nova dimensão do constitucionalismo garantista: a longo prazo, além de global, para além da lógica individualista dos direitos e da miopia, e do estreito localismo da política das democracias nacionais.AbstractThis article addresses the question of whether the stipulation of fundamental rights and obligations and prohibitions related to them is sufficient to properly ensure the needs and vital interests, especially those from collective interest. Fundamental goods are those whose access is guaranteed to each and every one since they are the object of fundamental rights, excluded from the logic of the market. The warranty for new goods and basic goods in the bottom of civilization requires a political decision to submit the right market relations. Thus, to the international charters and conventions and fundamental constitutional rights should be added Charters and international charter of basic goods. Hence the need for a new dimension of the constitutionally guaranteed: a constitutionally guaranteed in the long term, and global, apart from the individualistic logic of rights and shortsightedness and narrow localism policy of national democracies.

MÉTODO: Foi feita uma busca no banco de dados Medline de artigos publicados de 1966 até o presente para identificar aqueles relevantes para serem revisados neste artigo. DESFECHOS: Estudos pré-clínicos sugerem que a neuromodulação das monoaminas cerebrais está associada à tomada de decisões impulsivas e aos comportamentos de risco. Os estudos clínicos implicam diversos sistemas de neurotransmissores (serotoninérgico, dopaminérgico, adrenérgico e opióide na fisiopatologia do jogo patológico e de outros transtornos do controle dos impulsos. Estudos de neuroimagem preliminares têm indicado o córtex pré-frontal ventromedial e o estriato ventral como atuantes na fisiopatologia do jogo patológico e de outros transtornos do controle dos impulsos. As contribuições genéticas para o jogo patológico parecem substanciais e os estudos iniciais têm relacionado esse transtorno a polimorfismos alélicos específicos, ainda que os achados de varredura genômica ainda tenham que ser publicados. CONCLUSÃO: Mesmo que tenham sido logrados avanços significativos em nossa compreensão sobre os transtornos do controle dos impulsos, mais pesquisas são necessárias para ampliar o conhecimento existente e traduzir esses achados em avanços clínicos.OBJECTIVE: To review the neurobiological substrates of impulse control disorders. Pathological gambling is a main focus of the review in that most biological studies of the formal impulse control disorders have examined this disorder. METHOD: The medical database Medline from 1966 to present was searched to identify relevant articles that were subsequently reviewed to generate this manuscript

  15. Environmental monitoring of the Angra reactor site

    International Nuclear Information System (INIS)

    The single and sumarized results obtained under the monitoring program are presented and compared with those obtained during the preoperational period. Direct radiation was measured with a solid-state dosimeter network. The concentration levels of natural and artificial radionuclides were determined in primary media like air, surface and sea water, in accumulators like soil, sand and sediments, in indicators like grass and seaweed, and in the main local foodstuff, which includes marine produce (fish, shellfish and shrimps), milk bananas, manioc and oranges. The measurements included gross alpha and beta activity measurements and gamma spectrometry. Specific techniques were used for the measurement of the activity concentration of tritium in sea water and surface water and of I-131 in air and milk. The only detectable artificial radionuclide was CS-137 whose occasional presence in milk, pasture, fish and manioc can be attributed to world-wide fallout. (orig./PW)

    Full Text Available O presente artigo traz um resumo de dois estudos realizados na área do petróleo, o primeiro feito em uma unidade de refino e o segundo abarcando o trabalho de operadores exercendo várias funções dentro de uma refinaria e de terminais marítimos de petróleo. Nos dois casos, o ponto central foi a análise da atividade dos trabalhadores, isto é, o que eles faziam e como o faziam para dai conta das exigências de produção que lhes eram atribuídas. No entanto, os métodos utilizados foram diferentes: no primeiro caso utilizou-se a Análise Ergonômica do Trabalho (AET e no segundo, a Análise Coletiva do Trabalho (ACT. Além de apresentar os principais resultados destes estudos, a autora faz considerações sobre as diferenças entre os dois métodos e um apelo à comunidade científica para que se preocupe mais em estudar a atividade real dos trabalhadores e assim contribuir para um melhor conhecimento do que se passa no interior das unidades produtivas, evitando que sofrimentos humanos inúteis e até catástrofes industriais continuem a ocorrer.This paper describes two studies about petroleum industry. The first was developed in a refinery and the second focuses on the work of operators in various jobs within a refinery and maritime petroleum units. In both cases, the focal point was the analyses of activities, that is, what the workers do and how they do it in order to meet production demandai put on them. However, two different methods were applied in the studies. Ergonomics Work Analyses (EWA was used on the first case and Collective Work Analyses (CWA, on the second. Besides showing the main results, the author compares the two methods. She also draws the scientific community attention to the importance of studding the workers actual activity in order to contribute to a better understanding of what is going on inside production units, avoiding useless human suffering, and the still ocurring undustrial disasters.

    1996-05-01

    Full Text Available Os corretivos da acidez dos solos podem ter dois equivalentes em carbonato de cálcio: um, calculado pelos teores de cálcio e magnésio utilizando a expressão: % CaO x 1,79 + % MgO x 2,48 = %ECaCO3; outro, determinado analiticamente pelo poder ou valor de neutralização. Para uma mesma amostra ambos os valores deveriam coincidir, o que raramente acontece. Diversas hipóteses foram levantadas para justificar essa diferença. Os resultados deste trabalho permitiram inferir que nem todo o cálcio e magnésio dos corretivos devem estar associados às bases quimicamente efetivas mas também a fosfato, sulfato ou outras bases de forças inexpressivas; também os constituintes neutralizantes podem estar aprisionados em cristais de outros componentes dos corretivos, como sílica por exemplo, que só são atingidos por um ataque mais enérgico da amostra. Como conclusão, a avaliação química atual dos corretivos da acidez dos solos pode não estar se compatibilizando com o comportamento agrícola desses produtos.Agricultural liming materials can have two calcium carbonate equivalents: one calculated in function of calcium and magnesium oxide percentages, by the expression: % CaO x 1,79 + % MgO x 2,48 = %ECaCO3; and the other determined analytically by the neutralization power or value. For one sample, both values should be similar, however, this rarely occurs. Several hypoteses were raised to justify the difference. Results of this research permit to infer that not all calcium and magnesium should be associated to the chemically effective bases, but they are also associated to phosphate, sulphate or other bases of inexpressive strength. It is also possible that, the neutralizing components could be captured inside cristals, like silica for example, which react only after a strong solubilization of the sample. It is concluded that the chemical evaluation of agricultural liming materials at the present time cannot explain the agronomical behaviour of

Tres elementos ayudan a explicar esta permanencia: la tradición, que es asumida y reproducida por el "linaje de creyentes" pasados, presentes y futuros; el ritual, que reproduce la memoria histórica y la identidad local; y la apropiación de elementos culturales ajenos a la cultura local para sobrevivir en contextos globales. Estas celebraciones permiten restituir la armonía en los pueblos o barrios, que han cambiado drásticamente por la inserción de los mismos en un mercado mundial. También generan la percepción de tener el control de la comunidad frente a los grandes procesos externos que la amenazan: la mancha urbana, el comercio internacional, los medios masivos de comunicación, la cultura de masas, entre otros.

    2013-06-01

    Full Text Available Escherichia coli Direct Oxygen Sensor (Ec DOS, also known as Ec DosP is a heme-based O2-sensing phosphodiesterase from Escherichia coli that catalyzes the conversion of cyclic-di-GMP to linear di-GMP. Cyclic-di-GMP is an important second messenger in bacteria, highlighting the importance of understanding structure-function relationships of Ec DOS. Ec DOS is composed of an N-terminal heme-bound O2-sensing PAS domain and a C-terminal phosphodiesterase catalytic domain. Notably, its activity is markedly enhanced by O2 binding to the heme Fe(II complex in the PAS sensor domain. X-ray crystal structures and spectroscopic and catalytic characterization of the wild-type and mutant proteins have provided important structural and functional clues to understanding the molecular mechanism of intramolecular catalytic regulation by O2 binding. This review summarizes the intriguing findings that have obtained for Ec DOS.

  6. Modeling of the dispersion of tritium from postulated accidental releases from nuclear power plants

    International Nuclear Information System (INIS)

    This study has the aim to assess the impact of accidental release of tritium postulate from a nuclear power reactor through environmental modeling of aquatic resources. In order to do that it was used computational models of hydrodynamics and transport for the simulation of tritium dispersion caused by an accident in a CANDU reactor located in the ongoing Angra 3 site. It was postulated, then, the LOCA - Loss of Coolant Accident -, accident in the emergency cooling system of the nucleus ( without fusion), where was lost 66m3 of soda almost instantaneously. This inventory contained 35 PBq and was released a load of 9.7 TBq/s in liquid form near the Itaorna beach, Angra dos Reis - RJ. The models mentioned above were applied in two scenarios ( plant stopped or operating) and showed a tritium plume with specific activities larger than the reference level for seawater (1.1MBq/m3), during the first 14 days after the accident. The main difference between the scenario without and with seawater recirculation (pumping and discharge) is based on the enhancement of dilution of the highest concentrations in the last one. This dilution enhancement resulting in decreasing concentrations was observed only during the first two weeks, when they ranged from 1x109 to 5x105 Bq/m3 close to the Itaorna beach spreading just to Sandri Island. After 180 days, the plume could not be detected anymore in the bay, because their activities would be lower than the minimum detectable value (3). (author)

  8. Nucleoelectric energy dilemma in Brazil in the 1980's

    International Nuclear Information System (INIS)

    The production of electrical energy by nuclear reactors is unnecessary in Brazil. This technological option, which was concrete by the beginning of the 1970's, had its origins in the industrialized countries of the northern hemisphere. It signified a political ideological decision of an authoritarian and strategic nature, and not a technical scientific or ethical one. It began with the purchase of Angra 1 and was intensified in 1975, with the singing of the Brazilian-German Nuclear Agreement, establishing a double dependency: that of the nuclear reactors and that of combustion. The federal government was interested in the transference and command of technology, the production of electrical energy being secondary. Even through it was used as a justification for the country, the offer of electrical energy was already greater than the demand. In 1979, the Parallel Nuclear Program entered the scene. It was not subject to international inspections and was under exclusive control of the Armed Forces and the National Commission of Nuclear Energy, whose growing strength during the entire decade of the 1980's is notorious. At the same time, the Brazilian Nuclear Program lost in the 1980's the vitality that could be observed for the previous decade. It incurred accentuated technical errors and presented an extremely serious situation principally with regards to the emergency plan for the population of Angra dos Reis and neighboring cities and for the disposal of radioactive residues, which continue without a solution or definitive place. It is concluded that it is not possible to proceed with a energy policy that subsidizes electrical energy - the least expensive in the world - preponderantly to the industrial sector, for the private national and trans national initiative. In this situation there is no room for thermonuclear energy, onerous to the public coffers and dangerous to the population, to the natural environment and to the entire Planet.

    Wireless network is more vulnerable to denial of service (DoS) attacks than wired one. In this paper we propose two methods to resist DoS attacks in UMTS-WLAN network, one is active and the other is passive. These two are complementary to each other. In active DoS defense method, a mobile terminal generates an authorized anonymous ID (AAI) using its true ID such as IP address, MAC address, PIN code, or asymmetric key, and substitutes its true ID with the authorized anonymous ID. The mobile terminal may be authenticated by the UMTS-WLAN, however its true ID is anonymous to intending attackers. This method can be used to isolate de-authenticating/disassociating DoS attackers, spoofing power-save DoS attacker, etc. In passive DoS defense method, we propose a trace back scheme. We use covert channels in the header of mobile IP packets to trace back the malicious nodes by embedding some address information of intermediate nodes, and recovering the embedded information by the victim. After the victim successfully traces the attacking paths from malicious nodes, it can segregate the malicious nodes and protect itself. This method can be used to resist DoS attacks of mass-produced junk message congestions.

  2. OptaDOS - a new tool for EELS calculations

    International Nuclear Information System (INIS)

    Many modern (Scanning) Transmission Electron Microscopes ((S)TEMs) are equipped with an energy loss spectrometer. The Electron Energy Loss (EEL) spectra collected provide an experimental method of probing the bonding within a material. With the extra addition of monochromators, the energy resolution obtainable means that even more information is revealed within the fine structure of the spectra. Interpreting the fine structure can often be aided by simulation. Density-functional theory (DFT) is one method of simulating EEL spectra. DFT allows us to simulate DOS and EEL spectra from different structures. This comparison between simulation and experiment enables us to explore how changes in the spectrum are related to changes within the sample. CASTEP is a pseudopotential DFT code which can simulate both low-loss and core-loss EEL spectra. Recent developments have resulted in a separate analysis tool, OptaDOS. This package computes various spectral properties including DOS, projected DOS, joint DOS, core-loss and low-loss EEL spectra and optical spectra. One of the important aspects of the code is the way in which the DOS is calculated. This is done via linear extrapolation or adaptive smearing, methods which are not currently available within CASTEP (or indeed any other code) and which allow detailed analysis of spectral properties. This paper summarises these developments and what they mean for the interpretation of EEL spectra.

Em 2010, a Praça São Francisco recebeu o título de Patrimônio da Humanidade por ser fiel representante das construções hispânicas no continente americano. Esta pesquisa buscou analisar se a tutela da Praça São Francisco tem sido um contributo para a valorização cultural/patrimonial do centro histórico de São Cristóvão. Para tal, o artigo foi estruturado partindo de procedimentos metodológicos de construção descritivo-explicativa. Os resultados obtidos apontaram algumas ações educativas, investimentos na preservação do patrimônio, além da maior visibilidade do destino a partir da tutela da UNESCO. Entretanto, os residentes até o momento não perceberam vantagens desta titulação, que, conjugado à ausência de planejamento turístico, pouca qualificação dos informantes de turismo, inexistência de hotéis e restaurantes, tem inibido o crescimento turístico. Somados aos ruídos na comunicação entre a gestão pública municipal e os setores que atuam com o turismo na localidade, se constatou um escasso alinhamento entre os atores sociais responsáveis pelo desenvolvimento do turismo no centro histórico.

    The assessment of remediation measures for rural areas is more complex than that for urban ones, due to the influence of large number of variables associated with climate, diet, farming practices and the type of soil. Thus, it is not possible to perform generic studies applicable to all types of area. Specific studies and surveys should be made in the areas most likely to contamination from a nuclear accident. Preliminary studies demonstrated that the different soil types in Brazil is more relevant to the ingestion dose than the regional differences in diets. Other studies have described the prioritization of areas and products for detailed survey on soil types and remediation procedures, for an accident at the NPP in Angra dos Reis, based on radiological and economic aspects. The most relevant product was milk, due to both its relevance to the intake and the loss of income for the counties. The contribution of milk to dose depends on the season of the year when the accident occurs, mainly due to the relative contribution of other items of the diet. The timing of the application of the countermeasure has an important effect on the dose reduction that can be achieved. For I-131, protective measures must be considered within the emergency phase in order to be effective. The main action on reducing ingestion doses is the removal of food items from diet, while providing clean food to the population. (author)

  11. Remediation strategies after nuclear or radiological accidents: part 2 - accident scenarios for assessing effectiveness of cleanup procedures

    International Nuclear Information System (INIS)

    The selection of protective measures and remediation strategies after an accident needs to be based on previously established criteria, to minimize unnecessary stress and the exposures involved in cleanup operations that are not effective in reducing doses to the public. In a first stage, a database describing the countermeasures has been developed including their efficiency on removing contamination from surfaces. However, to assess the effectiveness of cleanup procedures in reducing doses to members of the public, it was necessary to derive specific scenarios in order to simulate the long term behavior of the material in the environment, since the contribution of different surfaces to doses changes with time after contamination. A basic release and exposure scenario was developed to assess the dose reduction due to the mostly used procedures. Exposure scenarios were selected to fit the surroundings of the Brazilian nuclear power plants in Angra dos Reis. Simulations were performed using SIEM, the integrated system for dose assessment after contamination events, developed at IRD. The contamination of urban environments was assessed for Cs-137, as this was found to be the most relevant long term radionuclide to contribute to doses to member of the public. The effects on reducing external exposures were assessed for periods up to 50 years after the contamination. For agricultural areas, the focus was on ingestion doses from contamination with I-131 for periods up to 1 year after contamination. Results will be complemented on the database in order to support multi-criteria decision making processes after accidents. (author)

  12. Reactor building 3D-model for evaluating the pressures on concrete regularization and foundation waterproofing membrane

    International Nuclear Information System (INIS)

    Angra dos Reis site in Brazil has already 2 operating PWR NPPs. Unit 3, with identical design to Unit 2, also a 1350 MW PWR, is expected to have its construction started in 2009. This new plant shall be founded directly on sound rock. The first step is to prepare this rock surface with a concrete regularization and a foundation waterproofing membrane. This study presents a 3D model approach of the corresponding reactor building to verify the maximum pressure acting on this surface. The 3D model permits to show a more realistic pressure distribution at every foundation specific detail. A static analysis is performed using ANSYS Mechanical Release 11.1. Dead weight, permanent and live loads, Safe Shutdown Earthquake (SSE) combined with Burst Pressure Wave (BPW) from the Feedwater Tank (SSB=SSE+BPW) and differences of temperature are taken into account. Considering all foundation nodes , the pressure distribution on the waterproofing membrane for each load case is obtained for vertical and horizontal directions, which corresponds to compression and tangential reaction loads. The maximum values occur in distinct positions for each load case. The maximum results are obtained according to DIN 25449 (2008) load combination criteria. The results are compared to a simplified analysis performed before, showing a good agreement in global values. (author)

  13. Priority of areas for agricultural radiovulnerability mapping

    International Nuclear Information System (INIS)

    The methodology for classifying areas according to soil properties for the vulnerability to a 137Cs contamination is of high importance to the preparedness related to nuclear and/or radiological accidents that lead to release of radionuclides to the environment with the consequent contamination of agricultural areas. The priority of research for agricultural areas should then focus on the surrounding areas of nuclear power plant that have higher probability of public exposure through the ingestion pathway. The objective of this work was to create a rank order for priority of areas to be mapped based on EMBRAPA database on soil properties. The 16 municipalities previously selected to define parameters for dose assessment simulations related to the Brazilian Nuclear Power Plants, located in the district of Angra dos Reis, Rio de Janeiro, have been investigated in order to create this rank order to direct the research on radio vulnerability mapping, considering their relevance to public exposure based on their agricultural productivity. The two aspects selected in this study account for the maximum loss of income and to the collective doses that can be averted due to the banning of agricultural products. These quantities are inputs to optimization analysis. The priority defined shall then guide research on both the adequate values for the transfer factors and on the agricultural countermeasures suitable to each area according to the cause(s) of their vulnerability and their typical agricultural crops.

  14. Remediation strategies after nuclear or radiological accidents: part 1 - database development

    International Nuclear Information System (INIS)

    The selection of protective measures and of remediation strategies of areas after a nuclear or radiological accident needs to be based on previously established criteria, in way to minimize the public's emotional stress and the exposure to workers involved in cleanup operations due to the implementation of procedures that are not effective in reducing doses to the public. Thus this work intended to develop a database which allows supporting the decision-making process after these accidents, by describing the foreseen strategies according to the type of accident and the type of affected environment, in order to be used in a multi-criteria selective process. To achieve that, in this first stage, the database has been developed including the following aspects: type of environment (urban, rural or aquatic); their contamination removal efficiency, as function of the time elapsed since the contamination event; the type and the amount of waste generated in the application of the strategy; the expected doses to the work team and basic needs such as specific materials, equipment, training, IPE, among others. The protection measures are usually described in literature considering their activity removal efficiency of a certain surface or environment. In order to determine their efficiency in the reduction of doses, a second stage is foreseen, involving the simulation of the implementation of the measures in different moments after the contamination, based on pre-defined accidents and scenarios, with focus on the surroundings of the Brazilian Nuclear Power Plants in Angra dos Reis.

    Two new chamigrane sesquiterpenes 1-2 and three known compounds 3-5 were isolated from a lipophilic extract of the red alga Laurencia dendroidea collected from the Southeastern Brazilian coast. Dendroidone (1) and dendroidiol (2) were isolated from samples collected at Biscaia Inlet, Angra dos Reis, Rio de Janeiro and at Manguinhos Beach, Serra, Espírito Santo, respectively. Debromoelatol (3), obtusane (4) and (1S*,2S*,3S*,5S*,8S*,9S*)-2,3,5,9-tetramethyltricyclo[6.3.0.0¹·⁵]undecan-2-ol (5) were obtained from specimens collected at Vermelha Beach, Parati, Rio de Janeiro. The structures of new compounds were elucidated by extensive NMR (¹H-, ¹³C-, COSY, HSQC, HMBC and NOESY) and high resolution mass spectrometry analysis. Additionally, the absolute configuration of compound 2 was assigned by X-ray analysis. Full spectroscopic data is described for the first time for compound 3. Anti-inflammatory and antimycobacterial activities of compounds 2-5 were evaluated. Compounds 3-5 inhibited the release of inflammatory mediator NO while TNF-α levels were only affected by 3. All compounds tested displayed moderate antimycobacterial action. PMID:24642907

    Continental flood basalts and dike swarm have been related to continental breakup process through geological time. The Resende - Ilha Grande Dike swarm (RIGDS) located in the southeast Brazil, is related the Gondwana breakup and composed of dikes/sills intruded in Precambrian gneiss. The dikes have three distinguish orientations: NNW more inland; NS-NNE in the central segment and NE orientation in the coast line, consistent with Precambrian structural lineaments. The swarm comprises high-TiO2 tholeiitic basalts divided into three suites based on REE and Sr and Nd isotope data. The Resende and Volta Redonda suites present higher initial 87Sr/86Sr ratios between 0.7077 and 0.7065, while Angra dos Reis suite presents values of 0.7066 to 0.7057. Geochemical and isotopic data support the sub-continental lithospheric mantle (SCLM) as the main source for the high-TiO2 basalts. The suites heterogeneities are explained by different compositions of SCLM in accreted Precambrian terranes and/or different degree of partial melting and fractional. 40Ar/39Ar data indicate age interval between ca. 156 to 144 Ma for the swarm, older than the average for Gondwana breakup (ca. 130-120 Ma). The age interval places the RIGDS between the Karoo magmatism (181-178 Ma) and the Paraná-Etendeka magmatism (133-134 Ma) and indicates that extensional process affected the supercontinent prior the break-up.

  18. Modeling the dynamics of radionuclide concentration in animal derived products after an accident in tropical areas

    International Nuclear Information System (INIS)

    Following an accidental release of radionuclides to the atmosphere with the contamination of large areas, a detailed and fast methodology to assess the prognosis of public exposure is needed to estimate radiological consequences and optimize decisions to the protection of the public. The German model ECOSYS has been chosen to integrate the SIEM - Integrated Emergency System, developed by IRD/CNEN to assess the doses to the public after an accidental contamination of rural areas. The use the model demands a considerable effort in adapting scenarios to fit the specific conditions of a location, considering the differences related to climate, environmental characteristics, agricultural calendar and practices, along with population diet. The area selected to start this adaptation considers the characteristics of the 50 km radius area surrounding the nuclear power plants at Angra dos Reis, Rio de Janeiro. At a first stage, the concentration on vegetal food products has been studied. This work describes the methodology used to select scenarios and presents results of the dynamics of the predicted concentration of radionuclides in different kinds of animal derived food products. The work provides guidance to the need of radioecological research needed to improve the adequacy of the estimates to actual Brazilian scenarios. (author)

  19. Planning the nuclear contribution to the Brazilian power programme

    International Nuclear Information System (INIS)

    Thermo-electric power in Brazil accounts for less than 20% of the total generating capacity. Brazil's power is essentially generated hydraulically, which ensures the growing development. The electric energy consumption keeps growing, with an annual average rate of 13% over the last five years. The present installed capacity is 20,000MW(e) and 185,000MW(e) are forecast for the year 2000. Most of the hydraulic resources are located in remote areas of the country very far from the consumption centres. In addition to the American-made nuclear power station under construction in Angra dos Reis with a power capacity of 626MW(e), the agreement signed in June 1975 between the Federal Republic of Germany and Brazil covers two more units, each of 1245MW(e) capacity, to be erected at the same site and planned to come into operation in 1982 and 1983. Several joint German-Brazilian companies will be established in the country for reactor and fuel manufacture. The Brazilian state holding nuclear company, Empresas Nucleares Brasileiras S A (Nuclebras), will participate in the formation of all joint companies with at least 51% of the capital investment. During the period of the agreement the Brazilian Government will encourage the development of technology and reduce the dependence on energy imports. Brazil's target is full independence in nuclear technology in about 15 years. (author)

    Abstract. This study aimed to test the hypothesis that smaller ants are more successful in exploring environmental interstices than larger ants, whereas environments with less rugosity are better for larger ants. The experiment was conducted in a secondary forest located in Angra dos Reis, Rio de Janeiro State (23 11’00’’S, 44 11’44’’O. Fourteen sites were randomly selected and in each site three plots (50cm x 50cm were demarcated. The leaf litter was removed from the plots and were applied treatments that simulated environments with different rugosity levels: low (no leaf litter, medium (only bamboo leaves and high (with leaf litter. Food baits were exposed in the center of the plots and the first ant that access the baits was collected. The total length of the ants was significantly lower in the treatment with higher level of rugosity (Tukey, p <0.05. The results confirmed the hypothesis that environments with high levels of rugosity favours smaller ants.

  1. External dose rates in coastal urban environments in Brazil

    International Nuclear Information System (INIS)

    A long term activity aiming on assessing the exposure of the Brazilian population to natural background radiation is being developed at IRD/CNEN. Several research groups within IRD work in this activity, although mostly as a parallel work associated to main research lines followed by researches of the institution. One main activity is related to the raise of external gamma dose rates throughout the country. The objective of this work is to present results from recent surveys performed as part of the emergency preparedness for radiological emergencies during major public events in Brazil, such as the the World Youth Day, held in Rio de Janeiro in 2013, and the Confederations Cup and the FIFA World Cup soccer games, in 2013 and 2014, respectively. In this work, only the recent (2014) coastal urban environments measurements were included. Average kerma rates for Fortaleza is 80 ± 23 nGy/h, for Vitoria is 96 ± 33 nGy/h and for Angra dos Reis is 147 ± 16 nGy/h. These results are then compared to previous results on other coastal urban towns (Rio de Janeiro, Niterói and Salvador), and with the high background coastal area of Guarapari town. (authors)

  2. Seismic risk map for Southeastern Brazil

    International Nuclear Information System (INIS)

    During the last few years, some studies regarding seismic risk were prepared for three regions of Brazil. They were carried on account of two basic interests: first, toward the seismic history and recurrence of Brazilian seismic events; second, in a way as to provide seismic parameters for the design and construction of hydro and nuclear power plants. The first seismic risk map prepared for the southeastern region was elaborated in 1979 by 6he Universidade de Brasilia (UnB-Brasilia Seismological Station). In 1981 another seismic risk map was completed on the basis of seismotectonic studies carried out for the design and construction of the Nuclear power plants of Itaorna Beach (Angra dos Reis, Rio de Janeiro) by IPT (Mining and Applied Geology Division). In Brazil, until 1984, seismic studies concerning hydro and nuclear power plants and other civil construction of larger size did not take into account the seismic events from the point of view of probabilities of seismic recurrences. Such analysis in design is more important than the choice of a level of intensity or magnitude, or adoption of a seismicity level ased on deterministic methods. In this way, some considerations were made, concerning the use of seisms in Brazilian designs of hydro and nuclear power plants, as far as seismic analysis is concerned, recently altered over the current seismic risk panorama.

The priority of research for agricultural areas should then focus on the surrounding areas of nuclear power plant that have higher probability of public exposure through the ingestion pathway. The objective of this work was to create a rank order for priority of areas to be mapped based on EMBRAPA database on soil properties. The 16 municipalities previously selected to define parameters for dose assessment simulations related to the Brazilian Nuclear Power Plants, located in the district of Angra dos Reis, Rio de Janeiro, have been investigated in order to create this rank order to direct the research on radio vulnerability mapping, considering their relevance to public exposure based on their agricultural productivity. The two aspects selected in this study account for the maximum loss of income and to the collective doses that can be averted due to the banning of agricultural products. These quantities are inputs to optimization analysis. The priority defined shall then guide research on both the adequate values for the transfer factors and on the agricultural countermeasures suitable to each area according to the cause(s) of their vulnerability and their typical agricultural crops.

    Full Text Available Two new chamigrane sesquiterpenes 1–2 and three known compounds 3–5 were isolated from a lipophilic extract of the red alga Laurencia dendroidea collected from the Southeastern Brazilian coast. Dendroidone (1 and dendroidiol (2 were isolated from samples collected at Biscaia Inlet, Angra dos Reis, Rio de Janeiro and at Manguinhos Beach, Serra, Espírito Santo, respectively. Debromoelatol (3, obtusane (4 and (1S*,2S*,3S*,5S*,8S*,9S*-2,3,5,9-tetramethyltricyclo[6.3.0.01.5]undecan-2-ol (5 were obtained from specimens collected at Vermelha Beach, Parati, Rio de Janeiro. The structures of new compounds were elucidated by extensive NMR (1H-, 13C-, COSY, HSQC, HMBC and NOESY and high resolution mass spectrometry analysis. Additionally, the absolute configuration of compound 2 was assigned by X-ray analysis. Full spectroscopic data is described for the first time for compound 3. Anti-inflammatory and antimycobacterial activities of compounds 2–5 were evaluated. Compounds 3–5 inhibited the release of inflammatory mediator NO while TNF-α levels were only affected by 3. All compounds tested displayed moderate antimycobacterial action.

    Full Text Available All snakebites registered in Rio de Janeiro state, Brazil, between 2001 and 2006 were analyzed. Of these, the snake species involved was identified in 2,431 cases, most of which were caused by Bothrops (2,347. Most victims were male (78.4% and the age group most frequently attacked was between 20 and 39 years (38.4%. As for severity, 1,118 (45.9% were classified as minor, 748 (30.7% as moderate, and 209 (8.6% as severe. Progression towards complete cure occurred in 1,567 patients; 39 had sequelae; three died; and clinical outcomes were not monitored in 822 cases. The time between bite and first medical attention was less than three hours in 74.6% of cases. Most occurred in municipalities with vast areas of preserved Atlantic Forest: Angra dos Reis (208, Rio de Janeiro (197, Parati (186, Teresópolis (134, and Petrópolis (110. Accident frequency was highest between November and April, in which the daily average is practically twice that observed in other months. Although results show that Rio de Janeiro state has a good level of medical care, it could be improved by creating multidisciplinary teams that include doctors, biologists, and nurses. The Vital Network for Brazil helps to promote a stimulating environment for this type of training, with both traditional courses and distance learning. Training hours must be increased to improve the skills of professionals responsible for victim care.

    Full Text Available Este artigo procura refletir sobre como a sistemática discriminação e violência contra os homossexuais, o que impede o próprio incremento da cidadania no Brasil, pois torna estruturalmente sancionada a exclusão e a desigualdade social. A principal questão é demonstrar que os preceitos constitucionais e os direitos fundamentais são violados quando são negados aos LGBT o direito à vida, à dignidade e à segurança. Assim, será defendida a tese de que a proteção e a promoção dos direitos desse segmento específico da sociedade significa também um ganho geral para o exercício da cidadania.

    We thank Meunier and Reis (hereafter as MR) for their comments on our paper. We, however, do not see the relevance of their alternative interpretation to our original results and believe this reflects their confusion regarding our conclusions rather than a discussion on physical mechanisms. In the context of this quote, note that even Pallé et al. (2009:3)admitted that “while the deseasonalized CERES data has a small year to year variability (Fig. 2 of Pallé et al., 2009), the Earthshine data seem to present overly large interannual anomalies, along with a large size of the error bars associated to the yearly means [which] is mostly due to sampling issues, as Earthshine measurements are taken from a single station.”To put this in a different way, the relatively short duration of Earthshine or satellite-borne measurements of global albedo is unable to provide the necessary information on how this important quantity may vary on multi-decadal timescales as studies by Soon and Legates (2013). We note that efforts to 'reconstruct' Earth albedo over a 120-to-130 year period have been discussed by Zavalishin (2014) but we stress that such research requires non-independent information regarding surface temperatures and some unproven assumptions about the thermal inertia of the hydrosphere.

La dinámica de crecimiento del siglo XX aportó configuraciones diferentes: las Villas Cerradas, las cuales incorporan paradigmas que dibujan un nuevo orden espacial. El trabajo aborda dos aspectos estrechamente vinculados: por un lado, la solución habitacional ofertada a grupos socioeconómicos de niveles medio y medio-alto, y por otro, cómo estos desarrollos establecen nuevos patrones en el quehacer urbano, y nuevos códigos y significados a la memoria colectiva de sus ciudadanos. Se revisa el statu quo de la acción planificadora y constructiva de la vivienda y se presentan nuevas experiencias realizadas en la década de los 90, las cuales a través de su arquitectura de grandes murallas expresan la autoprotección y el control disciplinario de las relaciones sociales. La investigación utiliza el análisis documental, planimétrico y la observación directa de los fenómenos urbanos como instrumentos de ayuda para dibujar los cambios producidos; lo cual será útil tanto para la comprensión de los procesos y su teorización crítica, como para la enseñanza, el ejercicio de la profesión y la planificación de la ciudad

    Full Text Available A noção de economista, longe de simples e evidente, é objeto de numerosas lutas de definição. O exemplo do campo dos economistas franceses, analisado a partir de um conjunto de entrevistas, observações de dados prosopográficos, revela certas características dessas lutas. Estas opõem detendores de formas diferenciadas de capital, que estão elas mesmas em correspondência com posições distintas no campo do poder. Nessas lutas, estão em questão ao mesmo tempo a autonomia e a estrutura desse campo científico. A fraca autonomia relativa do campo da ciência econômica se faz acompanhar de uma forte homologia entre a estrutura desse campo e aquela do campo do poder francês em seu conjunto.The concept of the economist, rather than being a simple and evident one, is the object of numerous conflicting definitions. The example of the field of French economists, as analysed in a set of interviews and the observation of prospographical data, reveal certain characteristics of these conflicts. These struggles oppose those who detain differentiated forms of capital, which are themselves in correspondence with distinct positions in the field of power. These conflicts put into question both the autonomy and the structure of this scientific field. The relatively weak autonomy of the field of economical sciences is followed by a strong homology between the structure of this field and that of the field of French power in its entirety.

Este artigo, descreve a experiência da “Cidade dos Meninos” e de seu idealizador, apoiando-se em teorias recentes sobre empreendedorismo social. Atenção especial é dada à definição de empreendedor social catalítico (WADDOCK; POST, 1991, relacionando a atuação da liderança da Cidade dos Meninos a esse perfil. Uma das possíveis conclusões é que, em países em desenvolvimento como o Brasil, o empreendedor social catalítico não pode exercer apenas a função de criador e implementador de políticas, face a dimensão da carência e do problema com o qual ele se confronta, envolvendo-se então na ação direta

    We define stealth Man-in-the-Middle adversaries, and analyse their ability to launch denial and degradation of service (DoS) attacks on secure channels. We show realistic attacks, disrupting TCP communication over secure VPNs using IPsec. We present: First amplifying DoS attack on IPsec, when deployed without anti-replay window. First amplifying attack on IPsec, when deployed with a `small' anti-replay window, and analysis of `sufficient' window size. First amplifying attack on IPsec, when deployed with `sufficient' window size. This attack (as the previous) is realistic: attacker needs only to duplicate and speed-up few packets. We also suggest a solution designed to prevent the presented attacks, and to provide secure channel immune to degradation and other DoS attacks. Our solution involves changes (only) to the two gateway machines running IPsec. In addition to their practical importance, our results also raise the challenge of formally defining secure channels immune to DoS and degradation attacks, and p...

A localização tumoral mais frequente foi torácica em 40% dos casos, seguida pela região cervical e cervicotorácica em 25,7%. Ao exame neurológico realizado entre 6 a 12 meses do pós-operatório, 42,9% dos pacientes demonstraram melhora, 34,3% permaneceram estáveis e 22,9% dos casos apresentaram piora. A ressecção foi total em 57,2% dos casos e subtotal em 37,1%. Em 5,7% dos pacientes, foi realizada apenas biópsia para diagnóstico. O grau de ressecção completa foi maior nos ependimomas (13 de 17 casos e menor nos astrocitomas (5 de 12 casos. Entretanto, o grau de ressecção e o tipo histológico não interferiram na morbidade pós-operatória. Fatores como sexo, idade e tamanho do tumor também não demonstraram importância na evolução após a cirurgia. A localização torácica do tumor foi associada a maior morbidade cirúrgica (p=0,021.

Todo hematologista habituado pode facilmente fazer o diagnóstico do estado da célula plasmocitária pela sua morfologia, seu tamanho e sua coloração. Nos quadros mais proeminentes de predominância de células de linhagem plasmocitária, os exames hematológicos e clínicos aliados ao mielograma, auxiliarão no diagnóstico do plasmocitoma. A nosso ver, os sinais (qualitativos, distintivos, de natureza citológica, que aparecem nos mielogramas no caso de plasmocitoma são: a Pleomorfismo e dismorfismo na célula plasmática; b "Rouleaux" de hemácias, já visível no hemograma; c Aumento das dimensões de alguns metamielócitos e bastonetes, acompanhados geralmente de atipias nucleares. Atipias e plurissegmentação nos segmentados; d No setor plaquetogenético aparecem plaquetas grandes e certo grau de perturbação nos megacarióticos, traduzido ás vezes pela presença de núcleos nus.Two hundred fifty bone marrow specimens, including twenty seven from hematologically normal patients, were examined hitologically. The Wright's and Brachet's stains were used. Plasma cells were rarely seen in the peripheral blood and bone marrow of normal individuals, but they were prominent constituents in some pathological states. A number significantly increased of plasma cells or mieloma cells were usually recognized in bone marrow from patients with plasmacytoma.

Já, as transformações realizadas sobre o corpo decorrentes da travestilidade, a decisão pela prostituição, a orientação sexual (por homem ou por mulher, e a construção de uma identidade sexual (gay ou travesti, apareceram como instâncias dissociadas entre si e relacionadas à busca da valorização pessoal e social diante do estigma atribuído ao gay afeminado, pobre e migrante. A religiosidade afro-brasileira e a gramática yorubá assumiram relevância para a constituição desta possibilidade identitária.In this work we propose to question how the speeches on sexuality, gender and sexual identity are built and validated, emerging from the life story of three homosexual brothers who were born in the inland areas of the Brazilian northeast.

    Full Text Available This experiment was conducted in 1994 at Ames, Iowa, US to test whether cytoplasmic male-sterility can be used to decrease barrenness and to increase grain yield of maize at two plant populations. Four genotypes were tested: a hybrid (NK 6330 and an inbred, wifh sterile and fertile counterparts. Each genotype owas evaluated at plant populations equivalent to 25,000 and 75,000 pl. ha-1. Hybrids produced higher grain yield than inbreds at both plant populations. Gram yield was higher at 75,000 than at 25,000 pl. ha-1. No difference in gram yield, number of ears per plant, number of grains per ear, tassel length, and tassel number of branches was found between sterile and fertile counterparts of the inbred and hybrid, regardiess of plant population. Fertile genotypes bore heavier tassels at anthesis than their sterile counterparts. Adequate precipitation distribution and high fertility level in the soil probably decreased competition between tassel and ears, mitigating potential yield benefits of suppressing genetically pollen production.Este experimento foi conduzido em Ames, Iowa, US durante o ano agrícola de 1994, tendo como objetivo avaliar se a macho-esterelidade genético-citoplasmática pode ser utilizada para aumentar o rendimento de grãos de milho em diferentes populações de planta.

    Full Text Available Los historiadores de la globalización periodizan dos grandes fases: una de 1860 a 1914, seguida de un período de desintegración de los flujos de capital, comercio y trabajadores, y otra de 1950 al presente. Este ensayo examina el comportamiento de la economía colombiana durante las dos globalizaciones. Aunque Colombia entró tardíamente a la primera fase, tuvo un comportamiento excelente, debido quizás a que partió de un punto muy bajo en la escala del desarrollo. Sus índices de comercio internacional y de participación en los flujos de capital se elevaron intensamente hasta 1930. En la segunda, el comportamiento fue relativamente mediocre; se erigieron altas barreras al comercio y a la inversión extranjera, mientras que se reprimió al sistema financiero en favor de agentes con poder político.

    Full Text Available A implantação do Sistema Único de Saúde - SUS, aprovada pela Constituição Federal de 1988, representou uma inovação política cuja característica central é a descentralização. Esta reforma do sistema de saúde vem transferindo aos municípios a missão de gestor único dos serviços de saúde no seu nível, numa inflexão nas normas e práticas até então vigentes. Este artigo trata das repercussões da reforma do sistema de saúde sobre as políticas de recursos humanos, focalizando o Estado do Rio de Janeiro e o nível municipal. Busca-se explicar algumas de suas insuficiências e contribuir para estabelecer novas bases e modelos para a política e gestão de recursos humanos no SUS. A pesquisa, que serviu de base ao artigo e à tese de doutorado, foi realizada no Estado do Rio de Janeiro e nos Municípios de Niterói e Angra dos Reis, que estavam enquadrados na categoria de gestão semiplena, segundo a Norma Operacional SUS Ol/93. Utilizando-se metodologia qualitativa foram feitas observações, coleta de documentos e entrevistas com gestores, técnicos e dirigentes de órgãos de representação de interesses dos trabalhadores, en quanto atores privilegiados das políticas e do processo de gestão de recursos humanos. Para a análise foi feito um recorte em torno de duas categorias: objetos do processo de regulação do trabalho e filosofia de gestão. Na primeira categoria foram consideradas como variáveis as definições dos planos de cargos e carreiras, da remuneração e da jornada de trabalho e, para a segunda, a participação na gestão, o processo de negociação e os programas de capacitação.The implantation of lhe SUS, approved by the 1988 Federal Constitution, represented a political innovation whose main characteristic is decentralization.

    Full Text Available A crescente complexidade dos desafios do setor da saúde implica um aumento das responsabilidades para aqueles que nela assumem funções de gestão. Há consenso que a qualidade da força de trabalho em saúde é um fator crítico para o sucesso de qualquer reforma no setor. O objetivo desta investigação é estudar e analisar a alteração induzida por uma intervenção de formação-ação intensiva na cultura organizacional de 73 diretores executivos dos Agrupamentos dos Centros de Saúde (ACES em Portugal durante a reforma na atenção primária à saúde. Os dados foram coletados e analisados em dois períodos temporais, antes e depois da intervenção do Programa Avançado em Gestão, Governação Clínica e Liderança para os ACES, o qual teve um ano de duração. O modelo Competing Values Framework permitiu observar que, depois da intervenção de formação-ação, as percepções dos diretores executivos sobre a sua cultura organizacional se encontram mais alinhadas com a reforma da atenção primária à saúde, valorizando o tipo de práticas e valores que esta defende. É necessário continuar a monitorizar os resultados em vários períodos temporais para elaborar conclusões a esse respeito.

    Full Text Available As plantas medicinais são utilizadas pelo homem desde o início da história e atualmente empregadas como recursos na medicina alternativa por grande parte da população mundial. Esse uso deve-se à facilidade de acesso às plantas em relação aos medicamentos alopáticos. O objetivo deste trabalho foi, primariamente, desenvolver uma análise cienciométrica sobre as tendências dos estudos com plantas medicinais no Brasil, investigando se o número de trabalhos cresceu ao longo dos anos. Além disso, foi identificamos as principais plantas que são estudadas pelo seu principio medicinal no Brasil. Para a pesquisa foi empregada a base de dados Scielo, com artigos de 1995 a 2011, utilizando a palavra “Planta Medicinal” como palavra-chave. Foram avaliados 329 artigos, mas somente 265 foram compatíveis à pesquisa. Artigos que não foram desenvolvidos no Brasil; que não utilizaram o termo planta medicinal; ou não citaram plantas foram excluídos das análises. Em cada artigo selecionado foram coletadas as seguintes informações: título do artigo, quantidade de autores, instituições responsáveis pelo estudo, local das instituições, ano de publicação, tipo de estudo (ex.: farmacológico, agropecuário e ecológico e as plantas que foram estudadas. Por meio de análises desses dados foi possível verificar as tendências dos estudos com plantas medicinais no Brasil. Conforme esperado, a maior parte dos artigos avaliados estão voltados para a Farmacologia, com aplicação em diversas áreas da saúde e em segundo lugar a Agropecuária, devido ao interesse em desenvolver produtos a partir de plantas para o controle de pragas. Entretanto, verificou-se o emprego em outras áreas, como a Bioquímica, Botânica, Ecologia, Genética/Molecular e Educação que apesar de serem menos frequentes, são essenciais, pois os estudos com plantas medicinais requerem profissionais de múltiplas áreas.

Este ensaio procura esclarecer os limites dos sistemas de medição, verificando se a utilização de metas de resultado é suficiente para que uma empresa tenha um desempenho superior. O objetivo é analisar a teoria das metas sob um olhar crítico, observando os limites da utilização de diversos tipos de metas, até mesmo no serviço público. Buscou-se fazer uma análise das pesquisas dos autores que defendem a utilização de metas para se ter desempenho e, a partir das suas premissas, analisar os estudos dos autores que as criticam, mostrando que elas podem causar, dependendo da situação, sérios danos financeiros e à imagem da organização. Após essa análise, verificou-se que as metas possuem um importante papel no aumento do desempenho da organização, todavia, deve-se ter certo cuidado na sua utilização, pois elas podem levar as pessoas a comportamentos não éticos, à inibição da cooperação e do aprendizado organizacional, entre outros.

    Full Text Available El artículo evidencia, por un lado, que las diferencias entre dos grupos de obras dentro del corpus hipolitiano, notadas por Nautin, y después desarrolladas sobre todo por Simonetti, son notables y deben ser aceptadas como demostración de la existencia de dos autores diferentes, abandonándose la todavía difundida "suspensión del juicio" sobre el tema, aun cuando algunos puntos secundarios permanecen inciertos. Por otro lado, sostiene que la escisión del autor romano en dos personas diferentes, inaugurada por el mismo Nautin (con su fantomático Josipo, y aceptada después -aunque con más prudencia- por Simonetti, Guarducci y otros a partir de 1989, no cuenta con un sólido apoyo. En cambio, fuertes indicios apuntan a la identificación entre los dos, y por tanto, a juicio del autor, debe aceptarse solo la existencia de: un Hipólito escritor romano y presbítero cismático (más tarde reconciliado por su martirio y venerado en la tradición romana; y de un Hipólito escritor asiático, obispo de sede desconocidaThis article, on the one hand, shows that the points of difference between the two groups of works among the Corpus Hippolytianum noted by Nautin, as well as developed and demonstrated above all by Simonetti, are fully convincing and must be accepted to demonstrate the existence of two different authors, even when several points of detail remain uncertain. On the other hand, the author also finds that the excision of the Roman personality into two, inaugurated by Nautin (with his phantom-like "Josipo", and accepted afterwards -albeit more prudently- by Simonetti, Guarducci and others beginning in 1989, has no firm base. Meanwhile, solid indicators point to an identification between the two, and therefore the existence of Hippolyte, Roman writer and schismatic presbyter (later reconciled by martyrdom and venerated in the Roman tradition must be accepted, in the author's judgment, at the side of Hippolyte, Asian writer and bishop of

    Full Text Available Neste artigo, a teoria de cópulas é utilizada para analisar os co-movimentos entre os mercados de capitais do Brasil e dos EUA. Na finalidade de implementação de uma estratégia de alocação de ativos é importante entender os eventos extremos - tanto os positivos (boom como os negativos (crashes - e seus efeitos sobre os mercados. Os índices de mercado usados são o IBOVESPA e o S&P 500 cobrindo o período de 03/2001 a 04/2007. A aderência aos log-retornos das principais cópulas encontradas na literatura financeira é avaliada. Os seguintes critérios foram escolhidos: o Log-likelihod, o critério de informação de Akaike e o critério de informação bayesiano. Os resultados mostram que a cópula de Joe-Clayton simetrizada é a mais adequada para modelar a estrutura de dependência entre os log-retornos do IBOVESPA e os do S&P500. Este trabalho difere de alguns estudos já realizados [e.g. Mendes e Moretti(2005 e Canela e Collazo(2005], pois leva em consideração a modelagem de cópulas dinâmicas introduzida por Patton (2006. Finalmente, através dos índices de dependência caudal ao longo do tempo, pode-se concluir que a ocorrência de eventos extremos negativos (crashes no mercado norte americano tende a afetar mais o mercado brasileiro quando da comparação da ocorrência dos eventos extremos positivos (booms.

    Full Text Available O trabalho a seguir configura-se como uma pesquisa de caráter teórico, que tem por objetivos compreender as noções de cultura e identidade e, a partir delas e de reflexões a respeito da história e da atuação dos movimentos LGBTTTIV, ponderar possibilidades de superação de práticas escolares heteronormativas. Primeiro, expõe considerações a respeito do conceito de cultura, o que inclui uma explanação acerca dos diferentes tipos de multiculturalismo. Em seguida, articula os conceitos de cultura e identidade, a partir dos quais se destacam os processos de reconhecimento e de representação, fazendo alguns apontamentos sobre igualdade e diferença. Depois, reflete especificamente a respeito das identidades sexuais e as contribuições das estruturas sociais que modelam tais identidades sem, no entanto, as determinarem. A partir disso, enfoca os movimentos LGBTTT como movimentos de ressignificação e resistência das práticas heteronormativas. E, por fim, conclui indicando o pensamento intercultural crítico e pós-moderno como aquele que pode repensar e desconstruir os mecanismos de exclusão das diferenças sexuais presentes no cotidiano escolar. Mas, também, como aquele que pode resgatar a problematização para o espaço escolar, constituindo-o como espaço de discussão, onde as verdades são abaladas. Trata-se do local onde é possível pensar, refletir e se colocar no lugar do outro. Um espaço no qual é possível ser diferente.

  9. Vaningi: O javali e a identidade dos Vanir

    Full Text Available Os Vanir, um dos grupos divinos do panteão nórdico, são frequentemente descritos como deuses da fertilidade e da terceira função no sistema proposto por Dumézil. Uma definição a meu ver simplista e anacrónica, dado que nem as grandes divindades nórdicas são meras abstrações funcionais, nem é de esperar que um panteão que conhecemos por fontes do século XIII tenha uma estrutura e dinâmica idênticas às que, hipoteticamente, existiam milénios antes entre os proto-indo-europeus. A chave para a identidade dos deuses Vanir deve ser antes procurada no javali, animal que, nas fontes nórdicas, surge profundamente ligado aos gémeos Freyr e Freyja e que tem uma simbologia que abarca não só a fertilidade, mas também a guerra.

    Full Text Available A angiotomografia é método diagnóstico rápido e minimamente invasivo que passou a ser utilizado recentemente nos casos de aneurisma intracraniano, possuindo 100% de especificidade e podendo atingir 95% de sensibilidade, na avaliação dos aneurismas do círculo de Willis, substituindo a angiografia digital, mas não em todos os casos. Apresentamos nossa experiência na avaliação do exame de angiotomografia tridimensional em período de 2 anos, comprendido entre junho de 1997 e junho 1999, em que foram realizados exames de angiotomografia tridimensional para detecção de aneurismas intracranianos em 136 pacientes Em 118 pacientes foi realizada apenas angiotomografia e em 18 casos foi realizada além da angiotomografia tridimensional, também a angiografia digital convencional. O exame de angiotomografia tridimensional possui baixo risco, sendo melhor utilizada na detecção dos aneurismas com diâmetro maior que 3mm. Possui algumas limitações, como os aneurismas muito pequenos <3mm aneurismas da carótida cavernosa e da circulação posterior, como também a não realização do exame dinâmico.

    Full Text Available A Mobile Ad-Hoc Networks (MANET is widely used in many industrial and people's life applications, such as earth monitoring, natural disaster prevention, agriculture biomedical related applications, and many other areas. Security threat is one of the major aspects of MANET, as it is one of the basic requirements of wireless sensor network, yet this problem has not been sufficiently explored. The main purpose of this paper is to study different MANETs routing protocols with three scenarios of Denial of Service (DoS attacks on network layer using proactive routing protocol i.e. Optimized Link State Routing (OLSR and Reactive routing protocols like Ad hoc On-Demand Distance Vector (AODV, Hybrid routing protocols like Geographic Routing Protocol (GRP. Moreover, a comparative analysis of DoS attacks for throughput, Data loss, delay and network load is taken into account. The performance of MANET under the attack is studied to find out which protocol is more vulnerable to the attack and how much is the impact of the attack on both protocols. The simulation is done using OPNET 17.

    RESUMO:A aldeia dos índios Potiguara não é somente um aglomerado de casas e pessoas. Trata-se de um espaço social muito mais complexo, somando ao habitat modelos de parentesco, cruzando práticas culturais e economicas, juntando aos humanos bichos e plantas, rotinas de trabalhos e “libertações” de lazeres. A aldeia Potiguara embora se apresente como singular, ela comunicava e continua a comunicar hoje com redes mais amplas de aldeias rurais e indígenas, gerando transformações culturais e socia...

    Full Text Available Os royalties do petróleo são compensações financeiras consequentes da exploração de petróleo ou gás natural. Devido à relevância da receita dos royalties do petróleo para a política fiscal e de desenvolvimento econômico do Rio Grande do Norte, e em particular, para os municípios que compõem a Área de Petróleo Potiguar, se fez necessário estabelecer um estudo sobre as suas influências na dinâmica socioeconômica dessa região. O objetivo geral desse artigo é investigar as contribuições das receitas extraordinárias, originadas da atividade industrial de petróleo no território potiguar, para a melhoria da qualidade de vida destes municípios. Assim, através da evolução dos índices de IDH-M vislumbrou-se observar se os royalties têm contribuído para o desenvolvimento humano nos municípios em estudo. Os dados para a pesquisa foram obtidos junto ao IBGE, ANP e FERMURN, e para analisar aevolução das duas variáveis – royalties e IDH-M – foi utilizada a metodologia descritiva. Ao final do artigo conclui-se que um dos fatores que ocasionaram na melhoria da dinâmica de desenvolvimento dos municípios da região foi o incremento dessa receita extraordinária nosorçamentos municipais, permitindo investimentos em programas que possibilitaram melhoria nas variáveis: renda, longevidade e educação. O resultado do coeficiente de Pearson (0,689apresentou que existe uma correlação positiva entre as variáveis no período de 1995 a 2000.

    Este trabajo presenta una descripción de la evolución de los ingresos absolutos y relativos en Argentina durante las ultimas dos décadas a la luz de las políticas macroeconómicas vigentes. Algunos de los resultados son contrastados con datos similares para la economía de los Estados Unidos. Si bien se nota una tendencia persistente hacia una mas desigual distribución del ingreso a lo largo de los 18 años, los resultados de la economía de mercado (1990-98) permiten una mayor dosis de optimismo...
