  1. Analysis of ADU structure obtained under different precipitation conditions

    International Nuclear Information System (INIS)

    ADU is the nominal name for ammonium poly uranate. It is a very complex compound of polymeric structure, which may have, according to precipitation conditions, different chemical composition and crystallographic structure. ADU is used as uranium oxide precursor in the manufacture of fuel elements. In former papers it was proved that if ultrasound is applied during precipitation and digestion the characteristics of the final product (U3O8 UO2) improve. By studying ADU thermal decomposition obtained by ultrasonic application, it was intended to obtain its composition. Therefore, differential thermal gravimetric and differential thermal analyses were performed. Samples were taken from special points and analyzed by X-ray diffraction, infra-red spectroscopy and scanning. An experiment was also designed to identify the products released during heating. Results and conclusions obtained are presented in this work. (author)

  2. Nuclear criticality data for uranium mass and sphere volume of homogeneous water-reflected and -moderated ADU

    International Nuclear Information System (INIS)

    The criticality calcucation to search for critical uranium mass and sphere volume, and subcritical uranium mass limit and sphere volume limit of homogeneous water-reflected and -moderated ammonium diuranate(ADU) was carried out with the JACS code system developed in Japan Atomic Energy Research Institute(JAERI) for criticality safety. Criticality calculations to search for these values were performed with the multigroup constant library MGCL and the multigroup Monte Carlo program KENO-IV of the JACS system. Uranium enrichment, uranium concentration, types of ADU, condition of the reflection and geometry were assumed as follows; 235U enrichment : 3, 4 and 5 wt%; Uranium concentration : ≤ (theoretical density of ADU); Types of ADU : ADU(II), ADU(III) and ADU(IV); Reflector : 30 cm thick water reflector was assumed around ADU; Geometry : sphere. Calculated critical and subcritical sphere radii under these conditions were converted into sphere volumes and uranium masses. These values show that (1) subcritical mass limit of three kinds of ADU described above decrease in order of ADU(IV), (III), (II), while (2) subcritical volume limit of ADU(III) and (IV) are less than that of ADU(II). There is a mixture of ADU(II), (III) and (IV) in the ADU process at nuclear fuel fabrication facility. From our results, the ADU mixture with less than 5 wt% enrichment can be safely handled up to 34.5 kg by uranium mass or 24.5 l by volume at the same time in the ADU process. (author)

  3. Calcination, Reduction and Sintering of ADU Spheres for HTGR Fuel

    International Nuclear Information System (INIS)

    The international oil market is again in turmoil in accordance with the increasing of human needs and energy consumption. Soaring oil prices, fears of supply security, and climate change are concerned becoming more concrete make for an uncertain energy future. In this view point, nuclear energy is an important, yet controversial option for energy supply. High Temperature Gas Reactor will play a dominant role in the worldwide fleet of nuclear reactors of the next decade for electricity production and high temperature heat. HTGR have two reactor types which use the basic fuel concept based on the dispersion of TRISO coated particles in graphite in shown Fig.1. The TRISO coated particle for these purposes is prepared with pyro-carbon and silicone carbide coatings on a spherical UO2 kernel surface as fissile material. The TRISO fuel particle consists of a microsphere (i.e., UO2 kernel) of nuclear material: encapsulated by multiple layers of pyro-carbon and a SiC layer. This multiple coating layers system has been engineered to retain the fission products generated by fission of the nuclear material in the kernel during normal operation and all licensing basis events over the design lifetime of the fuel. UO2 kernels are produced by using the modified sol-gel process, a wet process, generally known as the GSP method. Wet chemical processes are flexible in producing kernels of different size and chemical composition with high throughout and yield, good spherical shape, and narrow size distribution. This chemical processing route is well-known to the potential kernel fabrication processes. The principle, as set out in Fig.2, involves first of all preparing a pseudo-sol(also known as a 'broth') from an initial uranyl nitrate solution . This broth solution is obtained through addition of a number of additives, as determined by process know-how, including a soluble organic polymer, that are subsequently gels into droplets and are dispersed for ADU precipitation.

  4. Effects of two types of dryer on ADU and UO2 pellet manufacture

    International Nuclear Information System (INIS)

    The concepts of spray drying process and pebble-bed fluidized drying process for ADU slurry is presented. And the effects of ADU powder and UO2 powder/pellet by these processes using the statistic results from series production are discussed. It is believed that these drying methods have no influence on structure and shape of ADU particle, and thereby no difference will be made to the properties of UO2 powder and pellet. Thus, spray drying process can really be replaced by pebble-bed fluidized drying process. (10 figs., 6 tabs.)

  5. Purification of ADU and high-molybdenum AUC by recrystallization

    International Nuclear Information System (INIS)

    The ADU was converted to AUC by preparing pulp with (NH4)2CO3 concentrated solution, and then the prepared AUC (high-molybdenum AUC) crystals were dissolved with hot soft water for dissolution, and after filtration or clarification and scrubbing of the residue, and the clarified solution was digested and the obtained pulp was thickened and the thickened pulp was converted and recrystallized by adding (NH4)2CO3 concentrated solution. The crystals were washed and filtrated, and then the high-purity AUC crystals were prepared. The laboratory and pilot-plant scale experiments showed that the presented purification process was feasible with the solvent extraction step eliminated, so the chemicals consumption would be considerably decreased and the environmental pollution would be lowered. It is easy to realize the process in practice

    Ammonium poliuranate (ADU) is used as precursor of uranium oxides which are used as fuel for research reactors. The morphology of the oxides depends strongly on the structure of ADU. In this work we study the effect of acoustic energy of high frequency (ultrasound), on ADU precipitation for the obtention of U{sub 3} O{sub 8} and U O{sub 2}. Ultrasound changes ADU`s crystalline structure allowing the performance of a controlled precipitation. Experiences have been performed varying the times of ULTRASOUND appliance. X - Ray studies sustained the crystalline structure change. The difference in the state of agglomeration of particles was observed by electron scanning microscopy. This characteristic is maintained throughout the different thermal treatment performed on the powders (calcination at 800 deg C for U{sub 3} O{sub 8}, and 700 deg C in N{sub 2} - H{sub 2} atmosphere for U O{sub 2}). The oxides were characterized measuring specific area and particle size distribution. The results were good, being the change in the agglomeration state and ADU`s formula the most important features.

  8. U3O8 and UO2 obtained from ADU (ammonium diuranate) ultrasonically treated

    International Nuclear Information System (INIS)

    At present, obtention of U3O8 used in the manufacturing of MTR plates nuclear fuels, is performed by hydrolysis of UF6 to obtain uranyl fluoride. Uranyl fluoride is precipitated with ammonium hydroxide to get ammonium polyuranate (ADU). Afterwards ADU is calcinated to U3O8 and mechanical and thermally treated in order to obtain a powder in a determined specification. In the present work, ultrasound has been applied in the stage of precipitation of ADU and for different times in the stage of digestion in order to fasten the stages of ADU filtering and eliminate the U3O8 milling and sieving. Experiences on UO2 have also been performed. The aspect of ADU changes considerably when they have been ultrasonically treated, its filtering rate is faster and it is easier to dry as it contains less humidity. U3O8 obtained after 800degreeC calcination of treated ADU results in an easy to desagregate powder. Only a soft mechanical treatment is needed to be performed on it before starting thermal treatment at 1400degreeC. After thermal treatment at 1400degreeC treated U3O8 has shown adequate characteristics of size, shape and density (8.2 g/cm3). Regarding UO2, the shape of the agglomerates is almost spherical, leading to a free-flowing powder, whose apparent and TAP density showed to be adequate. The characteristics of the different compounds were followed by electron scanning micrographies, X-Rays, specific area measurements and differential thermal analysis. The great advantage of ultrasound appliance is that hard mechanical treatment is avoided in the obtention of U3O8, saving time and effort. Furthermore, UO2 proves to be adequate to make pellets, the same precursor could be used in the obtention of both uranium oxides. (author). 5 refs., 6 figs

  9. Characterisation and compaction behaviour of UO2 powder prepared from ADU and AUC

    International Nuclear Information System (INIS)

    UO2 powder prepared from ADU and AUC route process are characterised primarily in terms of compaction and sintering behaviour. Scientific understanding of the phenomena will give useful information leading to processing and product improvement. The investigation has been done by characterising the particle size/shape distribution using SEM and compacting the powder at 4 and 5.4 tons/cm2. The behaviour of the powder under compaction is observed by characterizing the pellet length, green density, microstructure, and the compression strength using micrometer SEM, and Universal Testing Machine. The results of the experiment show that the UO2 powder ex-AUC has particles of spherical type and separate individually which provide the flowable characteristic, important for the die filling aspect during compaction step. The UO2 powder ex-ADU is more or less agglomerated and contains very fine particles causing the difficulty in pressing. Therefore the green density resulted from UO2 ex-AUC (6.415 g/cm3) is higher than UO2 powder of UO2 ex-ADU (6.117 g/cm3. UO2 at lower pressure (4 tons/cm3) the compression strength ex-AUC green pellet (47.144 kgf) is lower than UO2 ex-ADU (63,364 kgf), and at higher temperature the compression strength of ex-AUC (92.86 kgf) is higher than UO2 ex-ADU (82.664 kgf). It is suggested that UO2 ex-ADU has to be precompacted and granulated in order to increase its flowability so that the pellet length can easily be controlled during pressing (improve reproducibility).

  13. Conversion of UF6 to UO2 - optimization of ADU [ammonium di-uranate] process

    International Nuclear Information System (INIS)

    ADU (Ammonium Di-Uranate) wet process, one of the most important routes for UO2 preparation from UF6, has been developed recently. This paper presents the test results of the process improvement. Both process variables and unit equipments were investigated intensively. The most important target of this task was to prepare high quality UO2 ceramic powder and pellet. From the test results of UO2 pelletizing and sintering, the operation conditions were selected for process optimization. The criteria used in optimum condition determination were compressibility, reactivity and sinterability of UO2 powder. Experimental results showed that UO2 pellets with sintered density higher than 98% of the theoretical density were reached. A quasi-optimum condition for ADU conversion process was also proposed.

  17. Carbon black selection from simulated broth solution for ADU gel spheres

    International Nuclear Information System (INIS)

    The VHTR (Very High Temperature Gas Reactor) is one of the reactor concepts in the Gen IV International Collaboration. The nuclear fuel of a VHTR in the US is based on microspheres containing a mixture of UO2 and UC2 coated with multi carbon layers and a SiC layer. This mixture is called a 'UCO (uranium oxi carbide)' kernel. The fabrication process of this kernel was based on the sol-gel method between an ADUN and HMTA and urea, a process referred to as internal gelation. UCO kernel microspheres were first prepared at ORNL in the late 1970s. CB(Carbon Black) as a carbon source in the final UCO kernel is added during the broth solution preparation, in the processing of UCO kernel fabrication. The preparation of a good quality UCO kernel is very difficult due to the homogeneous distribution of carbon in a UCO kernel. The key requirement to obtain a good quality kernel is a uniform distribution of carbon in the ADU gel sphere forming process before the thermal treatment, i.e., during the gel formation step. The internal gelation concept was adapted in ADU gel sphere fabrication in the ORNL process of the US. Generally, UO2 kernel microspheres are prepared by an internal gelation method (USA, India) or external gelation method (Germany, China, Japan). The UCO kernel microspheres prepared only in the US, use an internal gelation method. A material flow chart on the preparation of the microsphere kernel is simply shown in Fig. 1. The broth solution preparation, the raw material, additives, and thermal steps such as calcining and sintering processes were different to compared with the external gelation and internal gelation methods. In this study, we first carried out the matching CB selection experiments among the various kinds of CBs in a broth solution, for UCO kernel preparation using an external gelation method.

  20. Behavior of large grain UO2 pellet by new ADU powder

    International Nuclear Information System (INIS)

    In Japan, high burnup PWR fuel is being developed for assembly discharge burnups from 48 to 55GWd/t. As the pressure in the rods due to fission gas release from the pellets during the long burnup period is an important issue, some kinds of large grain pellets are being investigated in order to reduce fission gas release assuming their behavior will be as predicted by the simple diffusion mode. One kind of large grain pellet is manufactured from the highly sinterable powder produced by the new ADU (ammonium diuranate) process for converting UF6 gas to UO2+x powder. First, we checked the difference in the characteristics of the new active powder and the one in current use by investigating its pelletizing (pressing and sintering), densification, grain growth and microstructure (pore and grain structure). Secondly, we measured the thermal creep, thermal expansion and thermal conductivity of the large grain pellet, in out-of-pile tests. As a results, it was found that the thermal properties of the large grain pellet are the same as those of the current. ADU pellet except for thermal densification and creep behavior. Thirdly, irradiation experiments were performed in the Halden test reactor and the pressure and fuel stack length change in the rods were monitored at power. After irradiation up to about 20GWd/t, PIE has been carried out. It was confirmed that the fission gas release of the large grain pellet is lower and the in-pile densification is smaller than for pellets in current use. The reduction due to the large grain size is lower than expected from the Booth model because the fission gas release rate is very small and the effect of recoil/knockout is comparable to that of diffusion for a low linear heat rate. This paper compares the microstructure of the new pellet with its large grains and pores produced by a performer and a current pellet with normal sized grains and intrinsic pores. It also describes how this comparison relates the in-pile behavior of the

  1. Preliminary Studies Of Fluoride Analysis On Uranium Containing Samples (ADU) Obtained From Production Of UO2 Powder

    International Nuclear Information System (INIS)

    The study on quantitative determination of fluoride in uranium containing solid samples by using pyrohydrolysis technique has been carried out for the first time in Vietnam (at the Center for Analytical Chemistry-CAC, ITRRE, VAEI). The apparatus of pyrohydrolysis has thus been investigated for self-making firstly in CAC according to a structural scheme published in a literature. The preliminary studies on this self-made pyrohydrolytic apparatus showed that fluoride was separated from the sample matrix containing uranium (ADU) in water steam flow at 950oC within 30 minutes and condensed HF vapour through a water-cooling condenser was then collected at a flow rate of about 0.5 ml/min. in a PE flask. The fluoride concentration in solution was quantitatively determined with both electrochemical technique using fluoride ion selective electrode (ISE) and ion chromatography (IC). The recovery of fluoride analysis was achieved about 95 %. (author)

Liczne badania wykazały, że substancje, takie jak: ftalany, BPA, TBBPA oraz PCB charakteryzują się znaczną lipofilnością dzięki czemu w łatwy sposób wnikają do żywych komórek oraz akumulują się w tkankach i narządach. Niesie to za sobą zagrożenie dla zdrowia ludzi i zwierząt. Wymienione związki, ze względu na swoją budowę chemiczną, są zdolne do naśladowania endogennych hormonów np. estradiolu, zaburzając hormonalną homeostazę organizmu. Co więcej substancje te z łatwością pokonują barierę łożyskową oraz barierę krew-mózg i dlatego, jak wykazały liczne badania, zaburzają prawidłowe działanie układu nerwowego już od najwcześniejszych chwil życia. Udowodniono, że związki te wpływają na proces neurogenezy oraz transmisję synaptyczną, a w konsekwencji zaburzają proces kształtowania się płci mózgu, a także procesy uczenia, pamięci, zachowania. Ponadto ich cytotoksyczne i proapoptotyczne działanie może być przyczyną powstawania chorób neurodegeneracyjnych. Praca przedstawia aktualny stan wiedzy na temat oddziaływania ftalanów, BPA, TBBPA, oraz PCB na układ nerwowy.

    2014-01-01

    Full Text Available The article presents selected translations of Yiddish literature into English, focusing on the influence of translator’s choices on forming the topography and realities of life in Poland before the Second World War. Elements related to material culture and multilingual quality of represented world are often eliminated or simplified. One of the main problems for translators, who usually do not know Polish, are Polish words and expressions, which are frequent in Yiddish literature written by authors of Polish extraction. Additional problems occur when Polish is used as intermediary between Yiddish and Polish. A reader who knows Eastern European realities receives an image of reality, which has been purposefully modified to facilitate reception in America, so that represented reality turns out to be more alien and exotic than in direct translation from Yiddish into Polish. This phenomenon occurs not only in fiction, but also in documentary texts, e.g. in the memorial books, which have been popular in Poland recently, and which are often translated from English intermediary texts. All this leads to important discrepancies and tensions between reality as it is imagined, remembered, and documented. Examples presented in the article come from texts by Isaac Bashevis Singer, Shalom Asch, and the Zgierz memorial book.

Analysis of gathered data shows Chat romantic love activates not only subcortical regions, which mediates a variety of emotions involved in motivation and reward-seeking, but also activates higher cerebral areas involved in social cognition, attention, memory, mental association, and self-representation. Romantic love has its strongest base in ventral tegmental area and caudate nucleus, which are the primar regions of infatuation respectively. Other regions such as cingular cortex, posterior hippocamus, and hypothalamus deal with attachment bond, sexual desire, and inclusion of other in the Self.

    Although most patients with jejunoileal diverticulum are asymptomatic, a large, small-bowel diverticulum can be associated with midgut volvulus in an adult. We present a rare case of midgut volvulus that was associated with a large, small-bowel diverticulum in a 77-year-old woman presenting with chronic recurrent abdominal pain. The CT showed the characteristic whirl sign of twisted mesentery, the small bowel loops along the superior mesenteric artery and a large sac-like small-bowel diverticulum. A small bowel series also demonstrated a corkscrew appearance of proximal jejunum, a finding suggestive of midgut volvulus, and a large jejunal diverticulum. During the laparotomy, the small bowel was seen twisted counterclockwise 270 .deg.. The mesenteric root was very shortened. A 4 cm sized diverticulum was seen on the mesenteric border of jejunum, on the portion about 40 cm distal from the Treitz ligament.

    Full Text Available Oxytocin and vasopressin, “peptides of love and fear”, except for their classic role in control of labor and breastfeeding and blood pressure regulation, are also implicated in various processes like sexual behaviours, social recognition and stress response. These hormones seems to be essential for appropriate and beneficial social interactions, play a very important role in maternal care and closeness, promote general trust and cooperation and prolong social memory. They also play a very important role in modulating fear and anxiety response, especially by regulating the hypothalamic-pituitary-adrenal axis and amygdala activity by its projections to the brain stem and hypothalamic structures. Both hormones, particularly oxytocin, appears to be activating sexual behaviour or is responsible for increased sexual arousal. Evidence from clinical trials suggests their potential role in pathogenesis of schizophrenia, depression, autism and addiction together with possible therapeutic use in the above conditions. In schizophrenia, patients with higher peripheral oxytocin levels showed less severe positive, general and social symptoms and better prosocial behaviours. Literature suggests that exogenous oxytocin may be effective as an adjunctive therapy for that illness. Some data suggest that naturally occurring autoantibodies reacting with oxytocin and vasopressin are involved in depression, eating disorders and conduct disorder genesis.

    Full Text Available Forty years of communist leadership changed a lot of aspects of everyday living in Czechoslovakia. These changes intervened also to all rites of passage, including wedding. The new regime tried to suit traditional wedding and wedding habits to its conception. This new type of wedding should be simple, unified, civil and ideological. For example, a couple could not lawfully wed in a church anymore. For some time, brides also stopped wearing white wedding gown and replaced it by an ordinary dress. But there were many differences between state conception and reality. We want to show a real shape of getting married in communist Czechoslovakia, and therefore we used oral history and visual analysis of wedding photos. At first, we describe three similarities of marriages in socialism: hard-time in hunting for wedding dress, bouquet etc., very young marrying age and frequent pregnancy of bride in time of wedding. At second, we present two examples of evolution of wedding in the period 1948–1989. First example is development of wedding gown, influenced not only by fashion but also by political situation. Second example is a trend to close wedding in a family circle. In our opinion, this trend is the most important heritage of socialistic impression to wedding. The first day of marriage quit being public event and moved to living rooms.

  17. Study of processes for the preparation of U3O8 powder for MTR fuel elements

    International Nuclear Information System (INIS)

    Three preparation methods of high-density U3O8 powder have been studied: grinding of sintered U3O8 pellets, sintering of calcined U3O8 granules; and sintering of ammonium diuranate (ADU) granules. Experiments have been carried out varying ADU calcination time and temperature as well as sintering time, yielding ten U3O8 batches. Powder characteristics, granulometric yield, and number of process steps have been taken into account for comparison purposes. Impurity content, specific surface area, stoichiometry, morphology, density, porosity distribution and phase identification have been considered as parameters for powder characterization. The main conclusions show that the second method (following a 6000C/3h ADU calcination) gives the best results. Moreover, the third method gives also good results, but there were some difficulties with ADU handling. (author)

In all groups of patients partial correlation between the examined determinants of psychological and subjective assessment of symptoms and effects of its treatment was shown. The higher rating of the variables was most associated with a higher intensity of stress and anxiety.

  19. Comparative study of turbo and spray drying techniques in the production of nuclear grade uranium dioxide

    International Nuclear Information System (INIS)

    Natural Uranium Di-Oxide (U02) powder for the manufacturing of fuel for Pressurised Heavy Water Reactors (PHWR) is produced through the Ammonium Di-Uranate (ADU) route. The characteristics of the virgin U02 powder influence the sintered density of U02 pellets, which in turn is decided by the physical state of the starting material ADU. The physical characteristics such as the morphology, particle size, particle size distribution of ADU depend a lot on the precipitation and drying conditions. Different modes of drying are utilised on industrial scale to obtain sinterable grade U02 powder. Nuclear Fuel Complex, Hyderabad has successfully developed both the spray and turbo drying techniques for the production of dry ADU for further thermal treatment. Turbo drier is basically a bulk drier where the mechanism of drying is 'cross and through circulation'. The spray drier is a micro drier in which the slurry is atomised in a hot gas stream inside a chamber where drying takes place within a few seconds, because of high specific surface area. Design and operational parameters for the spray drier were optimised based upon the comparative study of product quality. Scanning Electron Microscope(SEM) images of ADU and U02 produced by turbo and spray dried routes were analysed. This paper deals in detail with the comparative studies carried out on both drying techniques, along with their behavior on further processing steps such as calcination, reduction, stabilization and sinterability of U02 powder.

  20. Study on the characterization and thermal decomposition of uranium compounds by thermogravimetry (TG) and differential scanning calorimetry (DSC)

    International Nuclear Information System (INIS)

    A contribution to the characterization of several uranium compounds obtained at the IPEN' Uranium Pilot Plant is given. Particularly, samples of ammonium diuranate (ADU) and uranium oxides were studied. The main objective was to know the stoichiometry of the ADU and the oxides resulting from its thermal transformation. ADU samples were prepared by batchwise precipitation, stationary dewatering into stove and batchwise thermal decomposition, or, alternatively, continuous precipitation, continuous filtration, continuous drying and continuous thermal decomposition inside a temperature gradient electrical furnace. All ADU were precipitated using NH3 gas from uranul sulfate or uranyl nitrate solutions. The thermal decomposition of ADU and uranium oxides were studied in an air atmosphere by thermogravimetry (TG) and differential scanning calorimetry (DSC). Any correlation between the parameters of precipitation, drying, calcination and the hystory of the obtaintion of the several uraniumm compounds and their initial and final composition was looked for. Heating program was established to have the U3O8 oxide as the final product. Intermediary phases were tentatively identified. Temperatures at which occurred the absorption water elimination, crystallization water elimination, evolution or oxidation of NH3, decomposition of NO-3 ion and oxygen evolution and the exo- and endothermic process for each sample were identified.

  1. Role of thermal analysis in uranium oxide fuel fabrication process

    International Nuclear Information System (INIS)

    The present paper discusses the application of thermal analysis, particularly, differential thermal analysis (Dta) at various stages of fuel fabrication process. The useful role of Dta in knowing the decomposition pattern and calcination temperature of Adu along with de-nitration temperature is explained. The decomposition pattern depends upon the type of drying process adopted for wet ADU cake (ADU C). Also, the paper highlights the utility of DTA in determining the APS and SSA of UO2+x and U3O8 powders as an alternate technique. Further, the temperature difference (ΔTmax) between the two exothermic peaks obtained in UO2+x powder oxidation is related to sintered density of UO2 pellets. (author)

  2. Fabrication of uranium dioxide of different granulation from uranyl nitrate by ammonia diuranate

    International Nuclear Information System (INIS)

    Uranium dioxide is most frequently produced by reduction of higher oxides (UO3, U3O8) or reduction of uranium salts (uranium diuranate, uranium peroxide, uranyl oxalate). Reduction is most frequently done in hydrogen or carbon monoxide atmosphere under temperatures from 500 - 1700 deg C. One of the most frequently methods for producing uranium oxide is certainly reduction of ammonia diuranate by hydrogen (ADU method). Properties of uranium dioxide obtained by ADU method depend on properties of the initial substance. Investigations shown in this report are concerned with determining the properties of UO2 powders for determining the connection between their properties and conditions of fabrication and reduction of ADU and U3O8

  19. Microstructural investigation on the effect of calcination temperature on UO3

    International Nuclear Information System (INIS)

    UO3 is one of the most important intermediate products in the nuclear fuel production. UO3 is produced by calcination of ammonium diuranate (ADU) and then subsequently it is reduced to UO2. Depending on the calcination temperature, the stoichiometry of the oxide changes which affects the final recovery in the fuel production. In the present study, microstructural changes in UO3 with the change in calcination temperature were investigated using scanning electron microscope (SEM). ADU slurry was produced by vapour ammonia precipitation of pure uranyl nitrate solution. Precipitate was filtered, dried and calcined in a pre calibrated furnace at different temperatures ranging from 450 deg C to 750 deg C. It was observed that basic microstructure of ADU, which consists of near spherical agglomerate of primary platelets, remains undisturbed during calcination. However, the formation and closure of internal porosities in those primary platelets of UO3 depend substantially on the calcination temperature of ADU. In the present investigation, very high resolution scanning electron micrographs of UO3 particles reveal the details of both internal and external porosities of the primary platelets in the structure. Thus the role of calcination temperature on the chemical reactivity of U-oxide powders and its microstructural evolution were demonstrated

  2. Comparative study of the different industrial manufacturing routes for UO2 pellet specifications through the wet process

    International Nuclear Information System (INIS)

    In the fuel cycle, converting UF6 to UO2 powder is an intermediate step for fabrication of pellets for fuel assemblies to be used in nuclear power plants. The basic proposal common to the different powder fabrication processes is to provide raw material capable of being processed into the form of pellets. The wet processes is the most often used industrially and are divided in two categories: the ADU (Ammonium Diuranate) and AUC (Ammonium Uranyl Carbonate) processes, whose names originate in the precipitate obtained in aqueous solution during the intermediate steps of UO2 powder fabrication. It has known that the powder characteristics have a considerable influence in the UO2 pellet manufacturing and quality characteristics. INB has used the AUC process to produce UO2 pellets and supply fuel to Angra 1 and 2 Nuclear Power Plants. Despite of this process is characterized by the precipitation of a different intermediate precipitate compared to the ADU route (i.e., (NH4)4UO2(CO3)3, in the AUC process, and (NH4)2U2O7 in ADU process) leading to some slight differences in the final pellet microstructure, it has been considered that the models that predict the pellet behavior during irradiation in a nuclear reactor are basically the same compared to those used to predict the pellets form the ADU process. In order to evaluate how different the pellets originated from these two industrial routes are, this paper aims to compare the INB production historical data (Angra 1, Cycles 14 and 15) with the key parameters of a common product specification from the ADU process.

    Adaptive optics is an important technology for improving beam quality in solid-state slab lasers. However, there are uncorrectable aberrations in partial areas of the beam. In the criterion of the conventional least-squares reconstruction method, it makes the zones with small aberrations nonsensitive and hinders this zone from being further corrected. In this paper, a weighted least-squares reconstruction method is proposed to improve the relative sensitivity of zones with small aberrations and to further improve beam quality. Relatively small weights are applied to the zones with large residual aberrations. Comparisons of results show that peak intensity in the far field improved from 1242 analog digital units (ADU) to 2248 ADU, and beam quality β improved from 2.5 to 2.0. This indicates the weighted least-squares method has better performance than the least-squares reconstruction method when there are large zonal uncorrectable aberrations in the slab laser system.

  6. Precipitation of ammonium diuranate from UO2F2 solution for fuel ceramic UO2 production

    International Nuclear Information System (INIS)

    Ammonium Diuranate (ADU) products with narrow particle size distributions, large specific surface area, and low fluorine content were precipitated from UO2F2 - HF solution in NH4OH solution in combination with a further precipitate aging. Settling rate of the precipitate particles, uranium content left in supernate, composition of the precipitates were determined. Experimental results show that, by converting UO2F2 - HF solution into soluble Ammonium Uranyl Fluoride complex (NH4)3UO2F5 (AUF) before precipitating, ADU precipitated in NH4OH solution at pH values in the range of 11.5 - 12, aged for 4 h possesses particle size distributions of 0.6 - 12 μm, specific surface area of 25 - 27 m2/g, the Fluorine content of about 1% after moderate washing.

    Most of the commercial nuclear power plants use uranium dioxide (UO2) as fuel due to physical and chemical properties of UO2. UO2 is a ceramic material it has low thermal conductivity and high melting point and therefore can be used in nuclear power plants. The nuclear grade uranium compounds are produced at Nuclear Fuel Technology Department of CNRTC using the following route: desolution and purification of yellow cake and precipitation of ammonium diuranate (ADU), calcination of ADU in air and reduction in hydrogen atmosphere to UO2. The UO2 powder characterized by specific surface area,particle size and O/U determinations. 0.2 % stearic acid is added to the UO2 powder and green pellets of 15 mm diameter are pressed. Hydraulic press with a floating die system and double pressing action is used. The gree pellets are then sintered

  8. Study and characterization of ammonium diuranate and uranium trioxide by thermogravimetry and differential scanning calorimetry

    International Nuclear Information System (INIS)

    Thermogravimetry (TG), Differential Thermogravimetry (DTG) and Differential Scanning Calorimetry (DSC) were used to characterize the thermal behavior of ammonium diuranate (ADU) and uranium trioxide (UO3) produced at IPEN'S Chemical Enginnering Department. Compounds characterization was done using the molar ratios among the compounds and the oxides resulting from thermal decomposition. The TG and DTG curves registered for each sample were used for the determination of the following temperatures: - temperature of water evolution (free and crystallized water); - ammonia evolution and oxidation temperature; - ocluded ammonium nitrate decomposition temperature and - oxygen release temperature. The intermediate phases and their thermal stabilities were also identified by TG and DTG and confirmed by DSC curves, DSC curves showed also the exothermic and endothermic behavior of the processes involved. Finally, the great amount of data collected in this study can be handed as a guide by the professionals responsible for the operation of ADU,UO3 and UF4 pilot plants. (Author)

  9. Recovery of enriched uranium from waste solution obtained from fuel manufacture laboratories

    International Nuclear Information System (INIS)

    Reversed-phase partition chromatography is shown to be a convenient and applicable method for the quantitative recovery of microgram to gram quantities of Uranium (19.7% enriched with 235U) from highly impure solution. The processing of Uranium compounds for atomic energy project especially in FMPP (fuel manufacture pilot plant) gives rise to a variety of wastes in which the Uranium content is of considerable importance. The recovery of Uranium from concentrated mother liquors produced from ADU (ammonium diuranate) precipitation, as well as those due to ADU washing is studied in this work. Column of Poly-trifluoro-monochloro-ethylene (Kel-F) supporting tri-n-butyl-phosphate (TBP) retains Uranium. Impurities are eluted with 6.5 M HCl, and the Uranium is eluted with water and the recovery of Uranium is better than 94%. (author)

    We investigated the effect of age and time of testing on the ability to control attention, and addressed the possibility that older adults’ susceptibility to distraction may sometimes facilitate performance on a later cognitive task. Using a modification of Rees et al. (1999), participants made same/different judgements on line-drawings superimposed with task-irrelevant letter strings. Memory for the distractors was subsequently tested using an implicit memory task. Both older and younger adu...

    Winslow, D. L.

    2005-10-01

    The Archimedes Demonstration Unit (ADU) has successfully separated a nuclear waste surrogate into light and heavy waste streams. ADU is a large scale (L = 3.9 m, a=0.37 m) cylindrical Plasma Mass Filter^1 that utilizes perpendicular electric and magnetic fields to generate a low-pass filter on atomic mass. This technology could reduce the volume of high level nuclear waste at the Hanford site in Richland, Washington. Over the last year, several techniques have been used to evaporate and inject waste surrogates into a rotating sodium metal plasma in ADU. Both spectroscopic and material collection techniques show that the Filter reduces the amount of heavy material in the light waste stream by a factor of 20 or more, with mass collection rates of about 0.25 g/s. Results of the experimental mass separation tests, parameter scaling of the mass separation, and supporting modeling will be presented. ^1T.

  4. Metabolism of uranium in the rat after inhalation of two industrial forms of ore concentrate: the implications for occupational exposure

    International Nuclear Information System (INIS)

    Aerosols produced from two commercially available ore concentrates in which the uranium was present essentially in the one as ammonium diuranate (ADU) and in the other as uranium octoxide (U3O8) were administered to rats. Uranium in the ADU bearing material was cleared rapidly from the lungs, the retention kinetics being similar to a class D (highly transportable) compound. Uranium in the U3O8 bearing material was removed from the lungs principally by mechanical processes, the retention kinetics being similar to a class Y (poorly transportable) compound. For both materials the distribution of uranium amongst body tissues and the fraction of the systemic content excreted in urine were similar to those obtained after the injection of soluble hexavalent compounds. For workers potentially exposed to both these materials, urine monitoring and lung radioactivity counting measurements should be used in addition to air sampling procedures for assessing the intake of uranium. Intakes of the ADU bearing material should be restricted to those permitted for short-term exposures on the basis of chemical toxicity, whereas those for the U3O8 bearing material should be governed by radiation dose.

The 2.4m telescope, which began working in 2008 May, is located at the Lijiang Observatory of Yunnan Observatories, where the longitude is 100°01'51''E and the latitude is 26°42'32''N, with an altitude of 3193m. There are two photometric terminals. The PI VersArry 1300B CCD camera with 1340*1300 pixels covers a field of view 4'48''*4'40'' at the Cassegrain focus. The readout noise and gain are 6.05 electrons and 1.1 electrons ADU-1, respectively. The Yunnan Faint Object Spectrograph and Camera (YFOSC) has a field of view of about 10'*10' and 2000*2000 pixels for photometric observation. Each pixel corresponds to 0.283'' of the sky. The readout noise and gain of the YFOSC CCD are 7.5 electrons and 0.33 electrons ADU-1, respectively. The 1.02m telescope is located at the headquarters of Yunnan Observatories and is mainly used for photometry with standard Johnson UBV and Cousins RI filters. An Andor CCD camera with 2048*2048 pixels has been installed at its Cassegrain focus since 2008 May. The readout noise and gain are 7.8 electrons and 1.1 electrons ADU-1, respectively.

  6. Thermoeconomic and environmental assessment of a crude oil distillation unit of a Nigerian refinery

    International Nuclear Information System (INIS)

    The renovation of refineries should be aimed at achieving the highest possible technical efficiencies at a considerable investment cost and not only at replacing damaged components to attain full capacity utilisation. This study examined a crude distillation unit (CDU) of a Nigerian refinery plant comprising the atmospheric distillation unit (ADU), vacuum distillation unit (VDU), preflash unit (PFU), splitter unit (SPU), stabiliser unit (SBU) and heat exchanger network (HEN) to determine critical areas of inefficiencies as the plant managements plan renovation. Using real plant data, the CDU was simulated with Aspen Hysys® and the thermoeconomic and environmental analyses were carried out. The results show that the energy and exergy efficiencies of the CDU were 9.0 and 4.0% respectively. The specific CO2 emission was 3.67 kg CO2/bbl. The highly inefficient subunits accounting for 77.4 and 90.0% of the overall energy and exergy losses respectively and 60.3% of the emission released were the PFU, ADU and HEN. The highly inefficient components are the furnaces which accounted for 51.6% of the overall exergy losses. The environmental and economic analysis also indicated that these components are the most potent for improvement. The columns of the PFU and ADU should be revamped to reduce their energy demands and the HEN should be modified to minimise effluent losses. - Highlights: •The assessment of a crude distillation unit (CDU) in Nigeria was carried out. •The assessment considered thermodynamic, thermoeconomic and environment analysis. •The assessment revealed areas with poor performance in the CDU. •Large thermodynamic and economic losses are responsible for the poor performance. •Areas with large losses and emission rate should be targeted for improvement

  7. Role of thermo-analytical techniques in compositional characterization of nuclear materials

    International Nuclear Information System (INIS)

    The study of heat effects on different materials has a long history. Extraction of metals from the ores, pottery production, glasses making etc. are the examples, where the performance of products obtained from raw materials depends on the processing temperatures. Concrete, pottery, bricks etc., are severely damaged due to uncontrolled high temperatures. Therefore, the heating of raw materials in controlled manner is of pivotal importance to get products of the desired quality. Thermo-analytical techniques provide the information on the effect of heat under controlled heating conditions. In thermo-analytical techniques, physical properties of materials are measured as a function of temperature. Simultaneous thermo-analytical techniques are beneficial in comparison to any single thermo-analytical technique. Simultaneous techniques refer to the measurement of two or more signals on the same sample at the same time in the same instrument. Nowadays, simultaneous thermo-analytical technique are extensively in use for the analysis of materials. Ammonium diuranate (ADU) and magnesium diuranate (MDU), also known as yellowcake, are intermediate precursors in fuel fabrication process, with stringent specifications along with the need to understand its thermal behavior. In the processing of lowgrade ores, higher levels of impurities are being encountered in the leach solution that affects the properties of ADU/MDU. In order to meet the fuel specifications, quality assurance of these nuclear materials is essential. Current studies describe the application of simultaneous Thermogravimetry (TG) - differential thermal analysis (DTA) - evolved gas analysis (EGA) techniques for the compositional characterization of ADU/MDU with respect to the impurities present in the matrices

    This article proposes an ontology based pattern recognition methodology to compute and represent common QoS properties of the Application Data Units (ADU) of multimedia streams. The use of this ontology by mechanisms located at different layers of the communication architecture will allow implementing fine per-packet self-optimization of communication services regarding the actual application requirements. A case study showing how this methodology is used by error control mechanisms in the context of wireless networks is presented in order to demonstrate the feasibility and advantages of this approach.

OBJETIVO: Avaliar as diferenças do padrão da marcha de indivíduos idosos ativos (ATI e sedentários (SED em relação aos indivíduos adultos (ADU durante a locomoção em um terreno inclinado (rampa. MÉTODOS: Quarenta e cinco indivíduos (15 ADU, 15 ATI e 15 SED caminharam, subindo e descendo uma rampa com 10% de inclinação. A análise cinemática (Vicon MX-13 e cinética (Plataforma de Força AMTI de variáveis relacionadas com a marcha foi realizada. RESULTADOS: Foram identificadas reduções na amplitude e potência do impulso ao redor do tornozelo dos indivíduos SED e ATI em comparação aos ADU durante a subida da rampa. Na descida, as principais diferenças entre o grupo ADU e os grupos SED e ATI foram com relação à velocidade de deslocamento, provavelmente por limitações musculares de ordem elástica, principalmente ao redor do quadril. CONCLUSÃO: Aparentemente, o nível de atividades físicas não influenciou a marcha dos SED e ATI; entretanto, uma limitação do IPAQ de conseguir classificar adequadamente diferentes níveis de atividades físicas pode ter influenciado o resultado. Futuros estudos longitudinais nos quais os indivíduos são submetidos a diferentes volumes de atividades físicas diárias são necessários para que os resultados aqui encontrados possam ser confirmados.

    Bisphenol-A (BPA) is one of the most widespread endocrine disrupting chemicals (EDC) used as the base compound in the manufacture of polycarbonate plastics. Although evidence points to consider exposure to BPA as a risk factor for insulin resistance, its actions on whole body metabolism and on insulin-sensitive tissues are still unclear. The aim of the present work was to study the effects of low doses of BPA in insulin-sensitive peripheral tissues and whole body metabolism in adult mice. Adu...

  12. Ceramic grade (U,Pu)O2 powder fabrication

    International Nuclear Information System (INIS)

    Ceramic grade UO2 powder was obtained by the homogeneous precipitation method. This procedure was afterwards applied to the fabrication of ceramic grade (U,Pu)O2 powders, and mixed oxide powders with Pu content ranging from 0.7 to 16% were obtained. The obtainment of mixed ceramic oxides as well as the recuperation of fabrication scraps were developed in three steps: 1)study of the process of homogeneous precipitation of ammonium diuranate (ADU); 2) co-precipitation of ADU/PuO2.H2O for Pu concentrations of 0.6 and 6.8; 3) the thermal conditioning to mixed oxide (U,Pu)O2 powders. The experimental procedure involves the following steps: preparation of the PuO2(NO3)4 solution; co-precipitation of the PuO2(NO3)2 solution with an UO2(NO3)2 solution; filtration and drying of the precipitate, thermal treatment and finally, mixing, pressing and sintering of the (U,Pu)O2 and Nukem UO2 powder with a 0. of zinc stearate. Different controls were made by means of physical, chemical and ceramographic tests. This method can be used for the fabrication of fast reactor fuels or, previous mechanical dispersion in UO2 powder, for the fabrication of thermal reactors fuels. (M.E.L.)

  16. Reduction and oxalate precipitation as an alternate route for uranium reconversion in thorex process

    International Nuclear Information System (INIS)

    Uranium reconversion at Uranium Thorium Separation Facility (UTSF) was carried out by ammonium-diuranate (ADU) precipitation followed by calcination. The significant iron contamination levels in the uranium product solution necessitated carbonate precipitation followed by neutralization before ADU precipitation thus rendering the process cumbersome. Also accumulation of ammonium nitrate in the process lines and equipments is a cause for concern in view of both choking up of the process lines as well as its potential hazard. However, these difficulties can be mitigated by the choice of oxalate precipitation route for uranium reconversion. As uranium can be precipitated as uranous oxalate the product uranyl nitrate needs to be reduced to uranous nitrate. Earlier studies in our laboratory revealed the feasibility of quantitative reduction of uranyl ion in the range 50 to 200 g/l with hydrazine nitrate as reducing agent in presence of PtO2 catalyst. However, in power reactor thoria reprocessing uranium product solution is expected to have a uranyl nitrate of about 4 g/l. So the feasibility of reduction of uranyl nitrate in this low range of uranium with hydrazine nitrate by the catalytic method was investigated and the precipitation of the uranous ion was carried out with oxalate and the supernatant was analysed for uranium losses

  17. Measurement of DNA strand breakage and DNA repair induced with hydrogen peroxide using single cell gel electrophoresis, alkaline DNA unwinding and alkaline elution of DNA

    International Nuclear Information System (INIS)

    Three techniques single cell gel electrophoresis (SCGE), alkaline elution of DNA, and alkaline DNA unwinding (ADU) were chosen to compare the sensitivity among these methods in detection of DNA damage and repair in human diploid VH10 cell line after short-term exposure to hydrogen peroxide. Using SCGE technique a dose-dependent increase in DNA migration was found in cell exposed to hydrogen peroxide in concentration range from 10 μmol/l. Alkaline DNA unwinding method detected increased level of single strand breaks (ssb) in concentration range from 25 μmol/l of H2O2, and alkaline elution of DNA estimated increased DNA elution rate from concentration 50 μmol/l of H2O2. In a time course study to evaluate the kinetics of DNA repair, both SCGE and ADU techniques showed that the repair of DNA strand breaks is very rapid; the level of ssb in treated cells has returned to near the background level within two hours. After this time damage remaining in the DNA was in the form of oxidised bases as revealed the incubation of treated cells with specific DNA repair endonuclease, formamidopyridine-DNA glycosylase.

  18. Process development study on production of uranium metal from monazite sourced crude uranium tetra-fluoride

    International Nuclear Information System (INIS)

    Development of an economic process for recovery, process flow sheet development, purification and further conversion to nuclear grade uranium metal from the crude UF4 has been a technological challenge and the present paper, discusses the same.The developed flow-sheet is a combination of hydrometallurgical and pyrometallurgical processes. Crude UF4 is converted to uranium di-oxide (UO2) by chemical conversion route and UO2 produced is made fluoride-free by repeated repulping, followed by solid liquid separation. Uranium di-oxide is then purified by two stages of dissolution and suitable solvent extraction methods to get uranium nitrate pure solution (UNPS). UNPS is then precipitated with air diluted ammonia in a leak tight stirred vessel under controlled operational conditions to obtain ammonium di-uranate (ADU). The ADU is then calcined and reduced to produce metal grade UO2 followed by hydro-fluorination using anhydrous hydrofluoric acid to obtain metal grade UF4 with ammonium oxalate insoluble (AOI) content of 4 is essential for critical upstream conversion process. Nuclear grade uranium metal ingot is finally produced by metallothermic reduction process at 650℃ in a closed vessel, called bomb reactor. In the process, metal-slag separation plays an important role for attaining metal purity as well as process yield. Technological as well economic feasibility of indigenously developed process for large scale production of uranium metal from the crude UF4 has been established in Bhabha Atomic Research Centre (BARC), India

  20. The utility of in vitro solubility testing in assessment of uranium exposure

    International Nuclear Information System (INIS)

    Assessment of accidental exposures in the uranium industry requires estimation of retention and excretion rates using bioassay measurements. This task is difficult if the solubility of the inhaled uranium compound is unknown. In our research, Beagle dogs were exposed to aerosols of commercial uranium milling products containing either pure ammonium diuranate (ADU) or U308. Dogs were exposed to ADU aerosols to achieve a median retained body burden of 0.058 mg U per kg body weight, or to U308 aerosols to achieve a median retained body burden of 0.28 mg U per kg. A biokinetic model was applied to simulate retention and excretion of the two forms of uranium in vivo. Comparison of published in vitro dissolution data and modelling results with information from accidental human exposures showed that in vitro dissolution studies are necessary to characterise the differential solubilities of uranium compounds, and indicate the potential for kidney toxicity. Because variability in pulmonary clearance and urinary excretion rates is high among individual people, in vitro dissolution results are only marginally useful for estimating urinary excretion rates.

  2. Spherical UO2 Size and Microstructure on Broth Preparation Conditions

    International Nuclear Information System (INIS)

    Without a doubt, the High Temperature Reactor will play a dominant role in the worldwide fleet of nuclear reactors of the next decade. It is being conducted by many countries, such as US, Japan, China, and so on, and mainly promoted for electricity production and high temperature heat. There are two general designs for He gas cooled reactor; types of the modular high temperature gas cooled reactor and the pebble bed reactor. Both reactor types use a basic fuel concept based on the dispersion of TRISO coated particles in graphite. The TRISO coated particle for these purposes prepared by pyro-carbon and silicone carbide coatings on a spherical UO2 kernel surface as a fissile material. Generally, UO2 kernels are produced by using the modified sol-gel process, wet process, known as the GSP(gel supported precipitation) method. This chemical route was well-known to the potential kernel fabrication processes. Figure 1 depicts a flow diagram of the VTHR fuel preparation process. After the formation of broth solution contained UN(Uranyl Nitrate) solution, PVA solution, and organic additives, spherical droplets are formed by a vibrating nozzle system. Spherical droplets are converted to liquid-ADU spheres in gelation column, and then finally aged-ADU gel particles in NH4OH solution. Following the drying and calcining, reduction of the calcined kernels to UO2 was carried out. This reduced UO2 particles were converted to a dense structure UO2 through the sintering process

  4. Effect of milling on the characteristics and sinterability of UO2 powders from different conversion processes

    International Nuclear Information System (INIS)

    The effect of ball-milling time on the change of powder characteristics, compaction behavior (compaction pressure range: 200-400 MPa) and sinterability (1700degC in H2 atmosphere) have been investigated for two different kinds of UO2 (ex-ADU and ex-AUC) prepared by wet processes. It is observed that, while the ex-ADU UO2 has little been affected, the ex-AUC UO2 powder has been largely affected by ball-milling treatment. This may be attributed to the characteristics of particle size formed during preparation step i.e., the former has a small average size of about 0.9 μm, while the latter has a relatively large one of about 28 μm. It appeared that the size reduction by ball-mill treatment is limited only to the particle size of larger than 1 μm, and to the extend of maximum decrease in size about 0.5 μm. In case of ex-AUC UO2, the powder particle size is observed to decrease with ball-mill time and, compact density and sintered density of ball-milled powder increased compared with those of as-received powder, under the same conditions. This may be mainly due to the fine particles formed by the ball-mill treatment. (author)

  5. Changes in UO2 powder properties during processing via BNFL's binderless route

    International Nuclear Information System (INIS)

    The Short Binderless Route (SBR) has been developed for Mixed Oxide fuel production in BNFL's MOX Demonstration Facility (MDF) and the Sellafield MOX Plant (SMP). It is a compact process which enables good homogenisation of the Pu/U mixture and production of free flowing press feed materials. The equipment used to achieve this consists of an attritor mill to provide homogenization and a spheroidiser to provide press feed granules. As for other powder processes, the physical properties of the UO2 powder can affect the different process stages and consequently a study of some of these effects has been carried out. The aim of the work were to gain a better understanding of the process, to consequently optimize press feed material quality and to also maintain powder hold-up levels in the equipment at a minimum. The paper considers the effects of milling processes on powder morphology and powder surface effects, on the granulation process and also on powder and granule bulk properties such as pour, tap and compaction densities. Results are discussed in terms of powder properties such as powder cohesivity, morphology and particle size. UO2 powder derived from both the Integrated Dry Route (IDR) and the Ammonium Di-Uranate (ADU) Route are considered. Small (1 kg) scale work has been carried out which has been confirmed by larger (25 kg) scale trials. The work shows that IDR powder with differing morphologies and ADU powder can be successfully processed via the SBR route. (author). 4 figs, 4 tabs

  7. Some recent improvements in a uranium processing pilot-plant at the Ningyo-toge mine

    International Nuclear Information System (INIS)

    Since 1964 the uranium processing plant at the Ningyo-toge mine has been modified and extended. In 1970 an ammonium diuranate (ADU) producing process was added to the plant, and a pilot plant with an ore-processing capacity of 50t/d was brought into operation. As a result of this operation the process which produces high-purity ADU was confirmed. An electrolytic reduction plant for the pilot operation was constructed by the Asahi Chemical Industry Co. in 1972. Experiments on the reduction of uranyl chloride solution were carried out with good results. Hydrofluorination facilities were added to the plant in 1974 and experiments on the hydrofluorination of UCl4 started. The experiments also studied the characteristics of hydrated UF4. Preliminary experiments on dehydration from hydrated UF4 were carried out to determine the dehydration conditions and the properties of the UF4 in the laboratory at the Tokai Works, PNC. The results of these dehydration experiments and UF4 conversion tests were excellent. (author)

  10. Morphology of uranium compounds

    International Nuclear Information System (INIS)

    Uranium metal is being used as nuclear fuel for Indian Research Reactors. During production of U metal various intermediate compounds of uranium are being processed. Physical, chemical properties of these compounds are important in overall processing rate and conversion determination. As no systematic data on morphology of these compounds were available, study was conducted to record the morphology of various U-compounds which are important in production of ceramic and metallic U-fuel for reactors. Most important intermediates were found to be ammonium diuranate (ADU) and uranium oxide (UO3/UO2). Morphology of these powders controls their flowability required for further material movement through different equipment, surface area required for chemical reactivity of powder, carryover losses occurred during gas solid counter current reaction and tap density required for effective capacity determination. ADU particle basically consists of primary platelets of 250-500 nm width and of 500-1000 nm length. These primary platelets form primary agglomerates. These agglomerates look like woollen balls or balls or cauliflower and primary agglomerates are also connected with each other to form secondary agglomerates. The basic morphology of ADU is maintained in UO3 even after calcination at high temperature. Pores are generated at the surface of platelet of UO3 due to release of gaseous reaction products during calcination. As temperature increases more pores are generated and sintering also starts. Specific surface area of UO3, produced by the calcination of ammonium di-urinate is generally a function of two competing processes: generation of surface area due to generation of pores because of the evolution of gaseous products (NH3, H2O vapour) and the loss of surfaces due to sintering. As a results surface area increases with calcination temperature due to generation of pores and then reduces. It has also been observed that morphology of the compounds are very much processing

  11. Study of the sintering process and the formation of a (Th, U) O2 solid solution

    International Nuclear Information System (INIS)

    The effect of some variables in the (Th, U) O2 sintering process and solid solution formation was studied. ThO2, U3O8 and UO2 powder were prepared. The ThO2 powders were obtained by calcination of thorium at 500 and 750 deg C; the U3O8 powders were derived from the calcination of ADU at 660 and 750 deg C; the UO2 powder were prepared from ADU and from ATCU. The different characteristics of these materials were determined by measurements of surface area, by scanning electron microscopy, tap density tests, X-ray diffractometry and by measurements of the O/U ratios. The oxide mixtures were chosen in order to produce a final composition with 10 w/o of UO2. A mixture of thorium oxalate and ADU was also prepared by calcining these salts in air at 700 deg C, in order to obtain certain amount of solid solution prior to sintering. The sintering operations were developed in an argon atmosphere at temperatures between 1400 and 1700 deg C, during interval varying from 1 to 4 hours. The effect of the mixture characteristics on the sintering process and solid solution formation were studied considering the results of densification, microstructure development and X-ray diffractometry. The ThO2 powder characteristics have a main effect on the mixtures compactability and sinterability, the higher calcining temperatures increasing the green density, but decreasing the final density of the sintered pellets. In the sintering of mixtures containing U3O3, this oxide is reduced to UO2 and it is possible to obtain pellets with density and microstructures similar to those produced from mixtures containing UO2. But if oxygen in excess is present during sintering, the process is affected, occurring exaggerated grain growth. The densification results were related to the Coble's kinetics equation for second stage of sintering, valid for bulk diffusion, grain boundary acting as vacancy sinks. The sintering activation energy is independent from the powder starting characteristics, its value

    Electrochemical decontamination process has been applied for recycle or self disposal with authorization of large amount of metallic wastes contaminated with uranium compounds such as UO{sub 2}, ammonium uranyl carbonate (AUC), ammonium di-uranate (ADU), and uranyl nitrate (UN) with tributylphosphate (TBP) and dodecane, which are generated by dismantling the contaminated system components and equipment of a retired uranium conversion plant in Korea Atomic Energy Research Institute (KAERI). Electrochemical decontamination for metallic wastes contaminated with uranium compounds was evaluated through the experiments on the electrolytic dissolution of stainless steel as the material of the system components in neutral concentration of electrolyte on the dissolution of the materials were evaluated. Decontamination performance tests using the specimens taken from a uranium conversion plant were quite successful with the application electrochemical decontamination conditions obtained through the basic studies on the electrolytic dissolution of structural material of the system components.

  14. New liquid waste control with tannin adsorbent

    International Nuclear Information System (INIS)

    Since 1971, the Mitsubishi Nuclear Fuel Co., Ltd. (MNF) has been fabricating PWR fuels and developing related technology and processes. In the UF6 reconversion lines of MNF, the ammonium diuranate (ADU) process has been operating and the newly developed process of liquid waste treatment was installed last year. The characteristic of this process is to use insoluble tannin adsorbent which has been developed by MNF. The tannin adsorbent is not only an effective means to adsorb heavy metals such as uranium and plutonium but is also easy to incinerate at low temperature. Control of radioactive liquid waste from nuclear facilities is generally implemented by co-precipitation. However, it produces secondary wastes such as noncombustible materials which include radionuclides and it is anticipated that the storage and disposal of those wastes will be at high cost. Those are the reasons why tannin adsorbent has an advantage, and why MNF develops it. (author)

  18. A mathematical model for estimation of distribution in the solvent stripping of uranium from TBP/n-paraffin ammonium nitrate

    International Nuclear Information System (INIS)

    The ammonium nitrate bearing effluent after ADU precipitation can be recycled as strippant in the stripping process of solvent extraction during uranium refining process. The nature of stripping of uranium with various concentration of ammonium nitrate as strippant was studied experimentally and a suitable theoretical model developed for the estimation of Distribution coefficient. The theoretical values of equilibrium constant distribution coefficient was estimated after employing the correction factors due to the activity coefficients each species at higher ionic strength. The activity coefficients of salts in aqueous solution were estimated the correlations developed by 'Bromley' for activity coefficients of multiple salt solutions. The model equations were developed by the mass balance of uranium at equilibrium for biphasic system. Solubility of TBP in water is not considered in the equation so developed. Also the model does not take into account for the ideality of organic phase

  19. Production of uranous nitrate with hydrazine nitrate as reducing agent in presence of Adams catalyst for uranium reconversion purposes

    International Nuclear Information System (INIS)

    The reconversion of 233U to its oxide was done through ADU route in Uranium Thorium Separation Facility (UTSF). As this process has some drawbacks an alternative route for uranium reconversion was envisaged. In this method uranium is first reduced to its tetra-valency and the tetra-valent uranium is precipitated as oxalate. Of the existing methods available for uranyl reduction, the reduction with uranium with hydrazine nitrate in presence of Adams catalyst was chosen and accordingly new equipment has been designed, fabricated and extensively tested for its performance. It was found that near 100 % conversion could be achieved even at the concentration normally encountered in PRTRF. As this method is simple and is amenable to remote operation, this method of reduction can be adopted in Power Reactor Thoria Reprocessing Facility. (author)

  1. Estimation of sensitivity factor for direct thoron progeny sensors in occupational environments of a reprocessing facility

    International Nuclear Information System (INIS)

    Direct Thoron progeny sensors are deposition based absorber mounted track detector, which can be used for measuring the long time-averaged progeny concentrations. Extensive measurements had been carried out in the indoor environments using these detector systems. In the present work, the field studies of these dosimeter systems carried out in the ADU Processing areas of Kalpakkam Reprocessing Plant has been reported. Since the sensitivity factor of these dosimeters is dependent on the deposition of progeny particulates on the detector surface, hence the various environmental processes governing the deposition, affect the sensitivity factor, especially the air exchange rates. Since higher air exchange rates are generally maintained in the Thorium processing plants, these dosimeters were first calibrated for the plant environment, and the calibration factor was obtained as 2.5 Tr cm-2d-1 / EETC (Bq m-3).

  7. Wet process of external gelation of uranium for preparation of uranium dioxide kernel of high temperature gas-cooled reactors

    International Nuclear Information System (INIS)

    In order to prepare the dense uranium dioxide (UO2) kernel for high temperature gas-cooled reactors (HTGR) fuel, the conventional sol-gel processes are optimized and modified. The wet process of modified extemal gelation of uranium (EGU) is introduced, which includes the dissolution of U3O8, i.e. the preparation of acid-deficiency uranyl nitrate, preparation of broth solution, casting and gelation of broth solution and aging, washing and drying of the gelled spheres, and etc. The mechanism of wet process of EGU is also discussed. With the optimized wet process, the ammonium diuranate (ADU) microspheres with good sphericity, uniform diameter and perfect porous structure are prepared. After the subsequent treatments of dry processes such as calcination, reduction and sintering, the eligible dense UO2 kernels for HTGR fuel are manufactured. (authors)

    2009-01-01

    A technique involving ^{55}Fe X-rays provides a straightforward method to measure the response of a detector. The detector's response can lead directly to a calculation of the conversion gain (e^- ADU^{-1}), as well as aid detector design and performance studies. We calibrate the ^{55}Fe X-ray energy response and pair production energy of HgCdTe using 8 HST WFC3 1.7 \\micron flight grade detectors. The results show that each K$\\alpha$ X-ray generates 2273 \\pm 137 electrons, which corresponds to a pair-production energy of 2.61 \\pm 0.16 eV. The uncertainties are dominated by our knowledge of the conversion gain. In future studies, we plan to eliminate this uncertainty by directly measuring conversion gain at very low light levels.

    O/U ratio is of high importance to both U3O8 and UO2 powders for different reasons. In UO2 powder it is a guiding parameter for sintering process where as for U3O8, it indicates efficiency of ammonium di-uranate (ADU) to U3O8 conversion process. In the present method for O/U determination, UO2 and U3O8 powders are dissolved in 4.5 M sulphuric acid and little HF by heating on hot plate. Subsequently, optimized quantity of phosphoric acid is added on cooling, for getting sharp end point. The resultant solution is titrated with standard potassium dichromate using barium diphenylamine sulphonate (BDS) as an indicator. The expanded uncertainties calculated for UO2 and U3O8 powders are ±0.004 and ±0.006 O/U ratio units respectively at 95 % confidence level. (author)

  19. Measurement of activation energy value for sintering of uranium dioxide powder compacts

    International Nuclear Information System (INIS)

    Uranium dioxide powder compacts prepared from their precursor Ammonium Di-Uranate (ADU) powders and calcined at various temperatures exhibit wide variations in their sintering behaviour. In general, it is observed that powders calcined below 8000C are non-crystalline in nature under X-ray diffraction studies and are highly sinterable (active) while those calcined above this temperature, designated inactive, exhibit poor sinterability. A model was proposed to measure the activation energy value for sintering these powder compacts. The model was based on a derived modification of Frenkel's sintering model as applicable to non-crystalline powders. The flow rate (ds/dt) leading to densification of the powder compacts was plotted against temperature, and the activation energy values were established. For low temperature (below 8000C) calcined powders an activation energy value of the order of 75 kcal/mole were observed. (orig.)

Results have shown detrimental effects of silica sand on the properties of natural rubber compound. It has been reported that when silica is used as a part for part replacement of carbon black, the heat build up the composite decreased whilst tear resistance improved. Results revealed that within the filler content range used in the present work, the hardness, modulus, and tensile strength of composites loaded with silica sand/carbon black showed enhanced magnitude over the composite loaded singly with silica sand. These parameters generally increased with increasing carbon black content in the composite. New area of use requiring moderate level of tensile strength, hardness and modulus (as in soles of shoes and engine mounts) is therefore opened up for silica sand.(author)

  7. Nuclear material control and accounting system evaluation in uranium conversion operations

    International Nuclear Information System (INIS)

    The Nuclear Material Control and Accounting Systems in uranium conversion operations are described. The conversion plant, uses ammonium diuranate (ADU), as starting material for the production of uranium hexafluoride. A combination of accountability and verification measurement is used to verify physical inventory quantities. Two types of inspection are used to minimize the measurements uncertainty of the Material Unaccounted For (MUF) : Attribute inspection and Variation inspection. The mass balance equation is the base of an evaluation of a Material Balance Area (MBA). Statistical inference is employed to facilitate rapid inventory taking and enhance material control of Safeguards. The calculation of one sampling plan for a MBA and the methodology of inspection evaluation are also described. We have two kinds of errors : no detection and false delation. (author)

  11. Recovery of uranium and thorium from secondary resources

    International Nuclear Information System (INIS)

    In the present paper an effort has been made to briefly describe first the effort that has been made at Rare Earths Division (RED), Alwaye, and Orissa Sands Complex (OSCOM) of IREL to recover nuclear grade ADU from uranium bearing monazite (0.35% U3O8) and other sources like thorium hydroxide (0.6% U3O8) and uranium fluoride concentrate (40%U). All these processes developed have similarity in the sense that they involve solvent extraction technology with novel combination of three different reagents falling in the category of acidic (PC88A) basic (ALAMINE-336) and neutral (TBP) extractants. Extensive R and D work in collaboration with uranium extraction division of BARC and plant scale trials have been completed to standardize the processes with respect to choice of ligands, composition of extractants, scrubbing/stripping reagents, number of stages as well as organic to aqueous ratios. Tons of ADU meeting the stringent specification have been produced and supplied to BARC for making uranium metal fuel for research reactors of the centre. In the case of uranium recovery from dilute phosphoric acid, the present paper is confined to use of a synergistic combination of DEHPA and TBP rather than well proven DEHPA-TOPO mixture. The primary motivation for examining this synergistic combination is the indigenous availability of both the solvent components since the supply of TOPO from the international market is likely to be denied. Based on the results of R and D test carried out at BARC large scale trials of various dilute phosphoric acids using experimental rigs consisting of carbon column, heat exchanger, commercial sized single stage mixer-settler, and plate separator are in progress at RED and OSCOM. IREL is also at advanced stage of pre-project activities and commercial negotiation with a number of host fertiliser companies like PPL, FACT and SPIC generating and using large volume of uranium bearing dilute phosphoric acid

  12. Fabrication of fuel for water reactors

    International Nuclear Information System (INIS)

    Nuclear Fuel Complex (NFC) established at Hyderabad in 1972, produces zircaloy clad uranium dioxide fuels for pressurised heavy water reactors (PHWRs) at Kota (Rajasthan), Kalpakkam (Tamilnadu), Narora (U.P.) etc., and boiling water reactors (BWRs) at Tarapur (Maharashtra). The experience gained at BARC in the production of zircaloy clad natural uranium oxide fuel for the initial core of the first PHWR at Kota, has been translated and utilised for establishing higher capacity fabrication plant at NFC. Natural uranium dioxide fuel pellets are produced starting with indigenous magnesium di-uranate concentrate from Uranium Corporation of India Ltd., Jaduguda (UCIL), a unit of the Department of Atomic Energy (DAE); and enriched uranium dioxide pellets from imported uranium hexafluoride and then fabricated into fuel elements and assemblies using zircaloy fuel tubes and components produced at NFC. For PHWR fuels the yellow cake, MDU, is purified through solvent extraction process and converted to ceramic grade uranium oxide powder via ADU route which is then pelletised and the pellets are loaded in zircaloy tubes which in turn are resistance welded with end caps to form elements. 19 elements with strip appendages are assembled into bundles with zircaloy end plates and the fuel bundles supplied to the various reactor sites. For BWR fuels the imported enriched uranium hexafluoride, in designated enrichments, is processed through ADU route to produce ceramic grade uranium oxide powder which is pelletised and the pellets loaded in autoclaved zircaloy tubes and the loaded tubes in turn TIG welded with end plugs to form elements. 36 elements of different U235 enrichments (including two elements of UO2-Gd2O3) are assembled in 6x6 array with stainless steel tie plates at the end, with the intermediate spacing maintained by zircaloy spacer grids.

Badania terenowe oraz modelowanie w warunkach laboratoryjnych skutków odprężenia warstwy zabezpieczającej w trakcie wydobycia są niezwykle czasochłonne i skomplikowane. Uwzględniając niejednorodność skał i wykorzystując dane geologiczne i o obecności gazów w kopalni Pindingshan 5, opracowano model numeryczny pękania skał w układzie gaz-ciało stałe w oparciu o analizę układu RFPA-Gaz. Model wykorzystano do symulacji zmian naprężeń, odkształceń stropu i spągu, propagacji pęknięć, przemieszczeń w pokładach zabezpieczonych, zmian w przepuszczalności gazów oraz migracji gazów w trakcie wybierania warstwy zabezpieczającej. Wyniki symulacji odwzorowują zmiany naprężeń, odkształceń stropu i spągu, propagacji pęknięć w trakcie wybierania warstwy ochronnej. Ruchy warstw górotworu scharakteryzowano poprzez analizę trzech stref nadkładu i dwóch stref lezących poniżej: w warstwach nadkładu: strefy zawału, strefy spękań oraz strefy osiadania (przemieszczenia w kierunku pionowym), w warstwach leżących poniżej: strefy odkształcenia i pękania spągu, oraz strefy odkształceń elastyczno- plastycznych w kierunku pionowym. Wykazano, że odprężanie miało miejsce w pokładzie zabezpieczającym, co prowadziło do powstania przemieszczeń pionowych oraz poziomych, zanotowano także znaczny wzrost przepuszczalności gazów, desorpcji gazów oraz ich transportu. Z tych względów zagrożenie wybuchem w pokładzie ochronnym zostało wyeliminowane.

  17. Development of coated particle fuel technology

    International Nuclear Information System (INIS)

    Ammonia contacting method for prehardenning the surfaces of ADU liquid droplets and the ageing/washing/drying method and equipment for spherical dried-ADU particles were improved and tested with laboratory sacle. After the improvement of fabrication process, the sphericity of UO2 kernel obtained to 1.1, and the sintered density and O/U ratio of final UO2 kernel were above 10.60g/cm3. 2.01 respectively. Defects of SiC coating layer could be minimized by optimization of gas flow rate. The fracture strength of SiC layer increased from 450 MPa to 530 MPa by controlling the coating defects. An effort was made to develop the fundamental technology for the fuel element compact for use in High Temperature Gas-cooled Reactor(HTGR) through an establishment of fabrication process, required materials and process equipment as well as performing experiments to identify the basic process conditions and optimize them. Thermal load simulation and verification experiments were carried out for an assesment of the design feasibility of the irradiation rod. Out-of-pile testing of irradiation device such as measurement of pressure drop and vibration, endurance test was performed and the validity of its design was confirmed. A fuel performance analysis code, COPA has been developed to calculate the fuel temperature, the failure fractions of coated fuel particles, the release of fission products. The COPA code can be used to evaluate the performance of the high temperature reactor fuel under the reactor operation, irradiation, heating conditions. KAERI participated in the round robin test of IAEA CRP-6 program to characterize the diameter, sphericity, coating thickness, density and anisotropy of coated particles provided by Korea, USA and South Africa. QC technology was established for TRISO-coated fuel particle. A method for accurate measurement of the optical anisotropy factor for PyC layers of coated particles was developed.

  18. Spherical UO2 kernel Particle Preparation for HTGR fuel in Korea

    International Nuclear Information System (INIS)

    A VHTR(Very High Temperature Reactor) is an important reactor concept for a near-term deployment under the nuclear R and D program of the Ministry of Education and Science Technology in Korea. The proposed nuclear fuel for the preliminary reactor concept is a TRISO(Tri-Isotropic or multi-layered structure) coated particle prepared by pyro-carbon and silicone coatings on a spherical UO2 kernel surface as a fissile material. Generally, the HTGR nuclear fuel production processes have been classified as five categories of research and development; - Spherical UO2 kernel preparation - Pyro-carbon(PyC) and silicon carbide(SiC) coatings - Pebble or Prismatic block preparation by using graphite matrix powder - Fuel performance including a fission products release - Advanced and improved fuel development Several proven fuel production processes are currently available for a spherical UO2 kernel production. The typical processes are an internal gelation process and an external gelation process. The well-known GSP(gel supported precipitation) process is one of the modified process for an external gelation method NUKEM of Germany. As developed above mentioned, both processes are based on the reaction of UN(Uranyl Nitrate, UO2(NO3)2)) and ammonia. The fundamental difference between the internal and external processes is in method of an ammonia supply to a liquid medium. The ammonia is supplied from an ammonium hydroxide solution within a gelation column in the external gelation process, whereas, in the internal gelation process, the ammonia is supplied from a thermal decomposition of an ammonia precursor solution which is included the HMTA(Hexa-Methylene Tetra Amine, C6H12N4) chemical. Here, the HMTA chemical contains the ammonia functional group at a low temperature condition. In this study, spherical ADU gel and UO3 particles via an UN solution as a raw material were prepared with the GSP process. And the spherical UO2 particles were obtained by a conversion of UO3 in a

Este trabalho relata o uso da técnica de mobilização do pisiforme na compressão do nervo ulnar no canal de Guyon de um homem que sofreu luxação do punho direito aos 8 anos e, aos 25, queixava-se de um deficit para adução do dedo mínimo, que atrapalhava a realização de algumas atividades de vida diária. O paciente foi submetido a uma única sessão de mobilização articular do pisiforme. Após a aplicação da técnica, o sinal positivo do teste foi eliminado, restabelecendo-se a função de adução do 5o dedo. Embora carecendo de maior fundamentação teórica, pode-se afirmar que a técnica usada, de mobilização articular do osso pisiforme, é eficaz para melhora do quadro de paresia por neuropraxia do nervo ulnar no canal de Guyon.A common ulnar nerve neuropraxia is lesion that may result in muscle strength decrease and/or paresthesia; it usually takes place at medial epicondyle level and the ulnar tunnel (Guyon's canal.

  1. The relationship of JNC and JCO in the uranium processing plant criticality accident

    International Nuclear Information System (INIS)

    On September 30th 1999, the criticality accident occurred at JCO's uranium conversion building in Tokai. The accident occurred during reconversion from U3O8 to uranium nitrate solution (UNH) with uranium enriched 18.8% and about 60 kgU. JCO contacted with JNC to supply UNH that is fuel material for the experimental fast breeder reactor 'JOYO'. JNC has contracted with JCO that had started nuclear fuel material processing business following a definite policy of Japanese government and developed SUMITOMO ADU PROCESS'. JNC made the first contract with JCO in 1985 and has made a contact every year. There had never been a problem in their products. JNC inspected products based on contract. JNC discharge our duty as customer inspecting products based on contract. As for safety control, JCO had taken licensing safety review and had been permitted to be 'a processing facility'. Therefore JNC understood that JCO produced following this license. 'The Uranium Processing Plant Criticality Accident Investigation' showed that JCO had been taking a different method from the permit and violating the license. However JNC had never been explained about that and JCO's operation procedures had never described about that. Therefore the Criticality Accident couldn't be avoided. This report describes the relationship of JNC and JCO in the uranium reconversion contract for JOYO, atomic development policy of Japanese government, process to the order and the contents of contract.

    1994-01-01

    Detailed monitoring of AGN's with FRESIP can provide well-sampled light curves for a large number of AGN's. Such data are completely unprecedented in this field, and will provide powerful new constraints on the origin of the UV/optical continuum in AGN's. The FRESIP baseline design will allow 1 percent photometry on sources brighter than V approximately equals 19.6 mag, and we estimate that over 300 sources can be studied. We point out that digitization effects will have a significant negative impact on the faint limit and the number of detectable sources will decrease dramatically if a fixed gain setting (estimated to be nominally 25 e(-) per ADU) is used for all read-outs. We note that the primary limitation to studying AGN's is background (sky and read-out noise) rather than source/background contrast with a focused telescope and by longer integrations. While we believe that it may be possible to achieve the AGN-monitoring science goals with a more compact and much less expensive telescope, the proposed FRESIP satellite affords an excellent opportunity to attain the required data at essentially zero cost as a secondary goal of a more complex mission.

    Electrolytic dissolution study was carried out to evaluate the applicability of electrochemical decontamination process using a neutral salt electrolyte as a decontamination technology for the recycle or self disposal with authorization of large amount of metallic wastes contaminated with uranium compounds generated by dismantling a retired uranium conversion plant using SUS-304 and Inconel-600 specimen as the main materials of internal system components of the plant. The effects of type of neutral salt as an electrolyte, current density, and concentration of electrolyte on the dissolution of the materials were evaluated. On the basis of the results obtained through the basic inactive experiments, electrochemical decontamination tests using the specimens contaminated with uranium compounds such as UO{sub 2}, AUC (ammonium uranyl carbonate) and ADU (ammonium diuranate) taken from an uranium conversion plant were performed in Na{sub 2}SO{sub 4} and NaNO{sub 3} solution. It was verified that the electrochemical decontamination of the dismantled metallic wastes was quite successful in Na{sub 2}SO{sub 4} and NaNO{sub 3} neutral salt electrolyte by reducing {beta} radioactivities below the level of self disposal with authorization within 10 minutes regardless of the type of contaminants and the degree of contamination.

  8. Uranium hexafluoride - chemistry and technology of a raw material of the nuclear fuel cycle

    International Nuclear Information System (INIS)

    Uranium hexafluoride exhibits an unusual combination of properties: UF6 is both a large-scale industrial product, and also one of the most reactive compounds known. Its industrial application arises from the need to use enriched uranium with up to 4% 235U as fuel in light water reactors. Enrichment is performed in isotope separation plants with UF6 as the working gas. Its volatility and thermal stability make UF6 suitable for this application. UF6 handling is difficult because of its high reactivity and its radioactivity, and special experience and equipment are required which are not commonly available in laboratories or industrial facilities. The chemical reactions of UF6 are characterized by its marked fluorination efficiency which is similar to that of F2. Of special importance in connection with the handling of UF6 is its extreme sensitivity to hydrolysis. Because they all use UF6, the isotope separation processes currently in use (gas diffusion, gas centrifuge, separation nozzle process) have a number of common features. For instance, they are all beset by the problem of formation of solid UF6 decomposition products, e.g. by radiolysis of UF6 molecules induced by its own radiation. Reconversion of UF6 into UO2 is achieved by three well-known methods (ADU, AUC, IDP-process). To produce uranium metal, UF6 is first reduced to UF4, which is subsequently reduced by Ca6 or Mg metal. 158 refs

Dla przykładu, procent osób w wieku powyżej 55 lat wynosił 30% w roku 2010, a w roku 2030 ma wzrosnąć do 37%. Jednak podnoszenie wieku emerytalnego nie powinno być jedynym sposobem na walkę z tymi problemami, jako że starszym osobom jest znacznie trudniej znaleźć pracę, choć z drugiej strony posiadają oni wiedzę, umiejętności i doświadczenie, które mogłyby zostać spożytkowane w działalności gospodarczej. Na świecie nasila się także tzw. trend „aktywnego starzenia”, który oznacza „proces optymalizacji szans dla zdrowia, uczestnictwa i bezpieczeństwa, aby poprawić jakość życia wraz z upływem lat”, który również zawiera koncept przedsiębiorczości osób starszych.

  17. The one-parameter-model - a constitutive equation applied to a heat resistant alloy

    International Nuclear Information System (INIS)

    In the present work a constitutive model earlier developed and used to predict experimental results of hot tests and fatigue tests from creep experiments of metallic materials were modified to comply with the properties of a high temperature resistant material. The improved model accounts for the properties of a material developing a density and a structure of dislocation lines which are capable of interactions with particles (carbides) from a second phase. The time and temperature dependent evolution of the carbide structure has been described by an equation which explains the formation of seeds as well as their growths (Ostwald ripening). The extended model was applied to Incoloy 800H which is known to develop a carbide structure. Therefore hot tensile and fatigue tests, creep and relaxation experiments using the heats ADU and BAK (KFA specifications) at temperature between 800deg C and 900deg C were performed including both solution treated specimens and specimens heat treated for 10, 100 and 1000 hours. As compared with the results from tensile tests where the carbide structures play a subordinated role, alternately, these structures have a decisive influence on the creep properties of specimens during the primary creep phase, i.e. low stresses and high temperatures.

  19. Nuclear fuel conversion and fabrication chemistry

    International Nuclear Information System (INIS)

    Following irradiation and reprocessing of nuclear fuel, two operations are performed to prepare the fuel for subsequent reuse as fuel: fuel conversion, and fuel fabrication. These operations complete the classical nuclear fuel cycle. Fuel conversion involves generating a solid form suitable for fabrication into nuclear fuel. For plutonium based fuels, either a pure PuO2 material or a mixed PuO2-UO2 fuel material is generated. Several methods are available for preparation of the pure PuO2 including: oxalate or peroxide precipitation; or direct denitration. Once the pure PuO2 is formed, it is fabricated into fuel by mechanically blending it with ceramic grade UO2. The UO2 can be prepared by several methods which include direct denitration. ADU precipitation, AUC precipitation, and peroxide precipitation. Alternatively, UO2-PuO2 can be generated directly using coprecipitation, direct co-denitration, or gel sphere processes. In coprecipitation, uranium and plutonium are either precipitated as ammonium diuranate and plutonium hydroxide or as a mixture of ammonium uranyl-plutonyl carbonate, filtered and dried. In direct thermal denitration, solutions of uranium and plutonium nitrates are heated causing concentration and, subsequently, direct denitration. In gel sphere conversion, solutions of uranium and plutonium nitrate containing additives are formed into spherical droplets, gelled, washed and dried. Refabrication of these UO3-PuO2 starting materials is accomplished by calcination-reduction to UO2-PuO2 followed by pellet fabrication. (orig.)

    International Nuclear Information System (INIS)

    KAERI (Korea Atomic Energy Research Institute) constructed a pilot plant for the uranium conversion process for the development of the technologies and the localization of nuclear fuels for HWR (heavy water reactor) in 1982. The final product of the plant was a UO2 powder of ceramic grade for HWR and its capacity was 100 ton-U/year. After that, a part of the AUC (Ammonium Uranyl Carbonate) process was added and the process was improved for automatic operation. 320 tons of UO2 powder was produced and supplied to the fabrication plant at KAERI for the fuel of the Wolsong-1 CANDU (Canadian deuterium uranium) reactor. The conversion plant has building area of 2916 m2 and two main conversion processes. ADU (Ammonium Di-Uranate) and AUC process are installed in the backside and the front side of the building, respectively. Conversion plant has two lagoons, which is to store all wastes generated from the plant operation. Sludge wastes stored 150m3 and 100m3 in Lagoon 1 and 2, respectively. Main compounds of sludge are ammonium nitrate, sodium nitrate, calcium nitrate, and calcium carbonate. In early 1992, it was determined that the plant operation would be stopped due to a much higher production cost than that of the international market. The conversion plant has been shutdown and minimally maintained for the prevention of contamination by deterioration of the equipment and the lagoon

  1. Electrolytic decontamination of the dismantled metallic wastes contaminated with uranium compounds in neutral salt solutions

    International Nuclear Information System (INIS)

    Electrolytic dissolution study was carried out to evaluate the applicability of electrochemical decontamination process using a neutral salt electrolyte as a decontamination technology for the recycle or self disposal with authorization of large amount of metallic wastes contaminated with uranium compounds generated by dismantling a retired uranium conversion plant using SUS-304 and Inconel-600 specimen as the main materials of internal system components of the plant. The effects of type of neutral salt as an electrolyte, current density, and concentration of electrolyte on the dissolution of the materials were evaluated. On the basis of the results obtained through the basic inactive experiments, electrochemical decontamination tests using the specimens contaminated with uranium compounds such as UO2, AUC (ammonium uranyl carbonate) and ADU (ammonium diuranate) taken from an uranium conversion plant were performed in Na2SO4 and NaNO3 solution. It was verified that the electrochemical decontamination of the dismantled metallic wastes was quite successful in Na2SO4 and NaNO3 neutral salt electrolyte by reducing β radioactivities below the level of self disposal with authorization within 10 minutes regardless of the type of contaminants and the degree of contamination

  4. MT topoiberia. Deep structure of a transect across the western Betic Cordillera (southern Spain)

    International Nuclear Information System (INIS)

    Complete text of publication follows. Two profiles combining long-period (LMT) and broadband data (BBMT) have been carried out within the context of Topoiberia project in the central and southern Iberian Peninsula. The main aim of this study is to provide new information about the crustal structure and mantle resistivity properties below the Betics, the Iberian Massif and the transition between both domains. The southern magnetotelluric profile is a 140-km-long profile that runs approximately NNW-SSE orthogonal to the major geological structures: from the internal zones of the Betic Cordillera, across the external zones, and onto the Guadalquivir foreland basin and the Iberian Massif. Data were acquired with Metronix ADU-06 (BBMT) and LEMI-417 (LMT) equipments and consist of fourteen broad-band MT sites and nine long-period MT sites. The studied period range is comprised between 10-4-104 s. MT data along this profile are integrated with other geophysical (gravity, magnetic, seismicity) and geological data to highlight the main crustal and upper mantle structure of the western Betic Cordillera. The new data contribute to discuss the recent geodynamic evolution of the western Mediterranean, where many controversial models have been proposed to explain the development of the Gibraltar Arch in the frame of the NW-SE Eurasian-African convergent plate boundary.

  5. A distributed CAN bus based embedded control system for 750 KeV DC accelerator

    International Nuclear Information System (INIS)

    This paper describes a distributed embedded system that uses a high performance mixed signal controller C8051F040 for its DAQ nodes and is based on CAN bus protocol for remote monitoring and controlling of various subsystems of 750 KeV DC accelerator based irradiation facility at RRCAT, Indore. A PC with integrated PCI CAN card communicates with intelligent DAQ nodes over CAN bus and each node is interfaced with a subsystem. An opto isolated SN65HVD230 CAN driver is interfaced between each node and physical bus. Remote frames and message prioritising are used for efficient control. The PC application is developed using LabVIEW 8.6. The proposed system is more reliable and noise immune as compared to previously used systems that initially used a centralized system based on C8051 controller. This was then upgraded to a distributed system that used microcontroller AduC812 and communicated over RS485 link. The new system has been integrated and tested satisfactorily for its designed performance with test jigs that simulated the actual subsystems with a bus length of 75 meters. First the complete scheme of the system is presented, and then the hardware and software designs are discussed. (author)

  7. Studies on supercritical fluid extraction of uranium from sodium diuranate

    International Nuclear Information System (INIS)

    Crude sodium diuranate (SDU) produced from phosphoric acid by solvent extraction process with di-2-ethyl hexyl phosphoric acid (D2EHPA) and tri-n-butyl phosphate(TBP) contains iron and other rare earth impurities along with uranium. For further use of this uranium for fuel fabrication and its subsequent use in nuclear reactors, it has to be purified up to nuclear grade ammonium diuranate (ADU) specifications. Conventionally crude SDU is being purified by dissolving it in nitric acid followed by solvent extraction process using TBP in diluent. Use of large amount of acid and organic solvents for industrial processes is an environmental concern. Nowadays there are efforts to minimize use of acid and organic solvents in industrial processes. Supercritical Fluid Extraction (SFE) of uranium from different matrices (solid as well as liquid) has been reported by several authors in recent years. Near complete extraction of uranium from UO2 (powder, green pellet and sintered pellet) using TBP-HNO3 adduct by SFE has been reported. We attempted to explore possibility to purify crude SDU to nuclear grade by SFE of uranium from crude SDU matrix and study the effect of different operational parameters, mode of extraction and complexation

    International Nuclear Information System (INIS)

    Nuclear energy is an inevitable option for meeting the ever-increasing demand of electricity without degrading the environment. Water-cooled reactors are currently in operation in our country where uranium dioxide fuel in the form of pellet encapsulated in zircaloy clad fuel pins are used. Nuclear fuel production is an established industry in our country and the fuel required is produced at NFC, Hyderabad for both Pressurized Heavy Water Reactor (PHWR) and Boiled Water Reactor (BWR). The raw material in the form of Magnesium diuranate (MDU) also known as yellow cake is received from UCIL Jaduguda and is processed through ADU route to produce ceramic grade UO2 powder, which is subsequently pelletised. The pellets are loaded in Zircaloy tubes and resistance welded with end caps to fuel element for subsequent supply in the form of fuel bundles to the reactors. The quality of the fuel supplied has to be ensured with respective to chemical composition and various other parameters like isotopic assay, mechanical strength and leak test for helium, etc. Thus determination of isotopic assay is an important part of the quality assurance programme. The isotopic assay is being carried out using Thermal Ionization Mass Spectrometry (TIMS) at Control Laboratory

  17. The relationship of JNC and JCO in the uranium processing plant criticality accident. The second revision edition

    International Nuclear Information System (INIS)

    On September 30th 1999, the criticality accident occurred at JCO's uranium conversion building in Tokai. The accident occurred during reconversion from U3O8 to uranium nitrate solution (UNH) with uranium enriched 18.8% and about 60 kgU. JCO contracted with JNC to supply UNH that is fuel material for the experimental fast breeder reactor 'JOYO'. JNC has contracted with JCO that had started nuclear fuel material processing business following a definite policy of Japanese government and developed SUMITOMO ADU PROCESS'. JNC made the first contract with JCO in 1985 and has made a contact every year. There had never been a problem in their products. JNC inspected products based on contract. JNC discharge our duty as customer inspecting products based on contract. As for safety control, JCO had taken licensing safety review and had been permitted to be 'a processing facility'. Therefore JNC understood that JCO produced following this license. 'The Uranium Processing Plant Criticality Accident Investigation' showed that JCO had been taking a different method from the permit and violating the license. However JNC had never been explained about that and JCO's operation procedures had never described about that. Therefore the Criticality Accident couldn't be avoided. The reports is the revision of former JNC TN8420 2003-003. (author)

  20. MT TOPOIBERIA. Long period measurements in the Iberian Massif (central Spain)

    International Nuclear Information System (INIS)

    Complete text of publication follows. Within the context of the Spanish TOPOIBERIA project a number of MT profiles are being carried out in Iberia and northern Morocco. The data are collected with recently acquired instruments consisting of 5 ADU07 (BBMT) and 10 LEMI-417 (LMT) systems, which make up a new Spanish pool of MT instruments. Two profiles with the LMT system have been carried out to date. One profile was undertaken in the Iberian Massif (Central Iberian Zone and Ossa Morena Zone) and the other across the Betic Chain in the south of Spain. Both profiles together form a 400 km long transect from the centre of Iberia to the Mediterranean Sea. We present the results of the first profile located in the eastern part of the Central Iberian Zone. The profile crosses the boundary between the Ossa Morena and Central Iberian zones and reaches the Tajo basin, crossing the Sierra de Alcudia and the Toledo Mountains. It is a 210 km long profile in a NE direction, from NW of Toledo to the province of Cordoba. The MT data consist of 31 BBMT sites (T=0.001-1000s) and 9 LMT sites (T=10-20000s). Dimensionality analysis indicates two directions, one for medium and the other for long periods. 2D inversions with different strikes in accordance with dimensionality analysis were performed in order to detect common features in the resistivity structure as a first step prior to a 3D inversion.

  1. A study of UF4 preparations

    International Nuclear Information System (INIS)

    Uranium tetrafluoride (UF4), green salt, is very important intermediate in the production of metallic uranium and uranium hexafluoride (UF6) for enrichment. The hydrofluorination of uranium dioxide (UO2) with anhydrous hydrogen fluoride (HF), produced from ADU (ammonium diuranate) process or AUC (ammonium uranyl carbonate) process, are commercially used for the production of uranium tetrafluoride. At present, a new approach such as direct UF4 preparation at the mine-site without further precipitation, filteration and drying of yellow cake from leaching solution has been studied. The single step continous reduction of uranium hexafluoride to uranium tetrafluoride is one of the most interesting process being applied for the commercial use of a large amount of depleted UF6 which is produced in tail after enrichment. The direct conversion of UF6 and UF4 with hydrogen and fluorine gases using cold wall reactor has a certain advantage over various wet process such as AUD and AUC processes in which hydrolysis of UF6 and various kind of chemicals are required, including liquid waste treatment. This report reviews and analyzes the theory and processes being used commercially or under study. (Author)

    International Nuclear Information System (INIS)

    An Inductively Coupled Plasma Mass Spectrometer was procured for trace elemental determination in diverse samples. Since its installation a number of analytical measurements have been carried out on different sample matrices. These include chemical quality control measurements of nuclear fuel and other materials such as uranium metal. Uranium peroxide, ADU, ThO2, UO2; isotopic composition of B, Li; chemical characterization of simulated ThO2 + 2%UO2 fuel; sodium zirconium phosphate and trace metallic elements in zirconium; Antarctica rock samples and wet phosphoric acid. Necessary separation methodologies required for effective removal of matrix were indigenously developed. In addition, a rigorous analytical protocol, which includes various calibration methodologies such as mass calibration, response calibration, detector cross calibration and linearity check over the entire dynamic range of 109 required for quantitative determination of elements at trace and ultra trace level,, has been standardized. This report summarizes efforts of RACD that have been put in this direction for the application of ICP-MS for analytical measurements. (author)

  5. Thermal decomposition of ammonium diuranate, uranyl nitrate hexahydrate and uranyl peroxide

    International Nuclear Information System (INIS)

    The behaviors of three types of starting powder had been investigated during their thermal decomposition processes in nitrogen, air, and hydrogen. The powder types were the products of uranyl nitrate precipitation, i.e. ADU (ammonium diuranate), UNH (uranyl nitrate hexahydrate), and UPO (uranyl peroxide). The objective of the investigation was to find out the best atmosphere that would result in good quality powder in a thermal decomposition process with the lowest temperature and the shortest period of time in order to reduce the cost of UO2 powder preparation. Before the thermal decomposition process was initiated, all powder types were characterized for their crystal structures. The investigation was conducted by TG-DTA instrument at temperature up to 800°C and the heating rate of 10°C/minute. The crystal structures were identified by X-Ray Diffractometer with Cu-Ka radiation. The specific surface area of the powder was also observed using BET method, especially for the powder that underwent the process in hydrogen heated up to 800°C. The Results showed that the process took place faster in hydrogen, and UNH required lower thermal decomposition temperature in relations with other types of powder. (author)

    The subject of the research concerned the coal samples from 360/1, 361 and 362/1 seams of the Orzesze beds in the "Pniówek" coal mine. The obtained samples were characterized by low ash content - 2.22- 6.27% of the mass. The chemical composition of the ash indicates the presence of aluminosilicate minerals in the analyzed coal samples - most likely clay minerals, the presence of which has been confirmed in microscopic tests of the petrographic composition of channel samples of coal. The content of rare earth elements (REE sum) in the ash of the tested coal seams ranged from 364 to 1429 ppm. Variation of the REE content has been observed within a single seam. The fraction of REE indicates a relation with a mineral substance. No relation of the REE fraction and the presence of red beds has been found based on the tested samples. The content of REE found in ash, normalized to chondrites, is characterized by LREE enrichment in relation to HREE. The Eu anomaly is most likely related to tuff and tonstein levels occurring in Orzesze beds, which accompany the coal seams in the Upper Silesian Coal Basin (i.a., south of the studied area). The research has indicated that LREE in the tested samples are more related to the mineral substance, while HREE have a stronger affinity with organic substances.

    International Nuclear Information System (INIS)

    Full text: The Industrias Nucleares do Brasil - INB is company with both private and public capital, linked to Comissao Nacional de Energia Nuclear-(CNEN) and to the Brazilian Ministry of Science and Technology. It has facilities in the states of Bahia, Ceara and Minas Gerais, with corresponding uranium mining and milling plants, which represent the first stage of the Nuclear Fuel Cycle. Caldas Unit (decommissioning phase) -First mineral-industrial complex settled in the country, located in the municipality of Caldas, at the southern State of Minas Gerais, since 1982. Here the development of the nuclear fuel cycle technology was started aiming at generating electric power, through uranium processing by chemical treatment and its transformation into yellowcake. Due to the exhaustion of the economically feasible uranium, the facility stopped its production in 1996, and the priority was to transfer the mining activities to Caetite (BA) in the late nineties. Caetite Unit (operational phase) - One of the most important Brazilian uranium ore provinces, is located in the southwest of the state of Bahia, near the towns of Caetite and Lagoa Real. The mining of uranium ore, with average content of 2 900 ppm in U3O8 equivalent, is underway since 1999 in an open pit mine at the Cachoeira deposit. Milling takes place at the industrial facilities for the extraction of uranium through acid heap leaching in piles, and concentration and purification through solvent extraction in countercurrent method, followed by the production of the corresponding concentrate as ammonium diuranate - ADU, or yellow cake. The current yearly production of ADU reaches 400 metric tonnes in U3O8 equivalent. The next step, presently being licensed, will be a shift on the mining process, from open pit to underground mining, aiming at a more economical exploration of the ore. It will be the first underground uranium mine in our country. Santa Quiteria Unit (implementation phase) - The Santa Quiteria

  13. MOX fuel development: Experience in Argentina

    International Nuclear Information System (INIS)

    Since 1973, when a laboratory conceived for the safe manipulation of a few hundred grams of plutonium was built, the CNEA (Argentinean Atomic Energy Commission) has been involved in the small-scale development of MOX fuel technology. The plutonium laboratory consists in a glove box facility (α Facility) featuring the necessary equipment to prepare MOX fuel rods for experimental irradiations and to carry out studies on preparative processes development and chemical and physical characterization. The irradiation of the first prototypes of (U,Pu)O2 fuels fabricated in Argentina began in 1986. These experiments were carried out in the HFR (High Flux Reactor)- Petten , Holland. The rods were prepared and controlled in the CNEA's a Facility. The post-irradiation examinations (PIE) were performed in the KFK (Kernforschungszentrum Karlsruhe), Germany and the JRC (Joint Research Center), Petten. In the period 1991-1995, the development of new laboratory methods of co-conversion of uranium and plutonium were carried out: reverse strike co-precipitation of ADU-Pu(OH)4 and direct denitration using microwaves. The reverse strike process produced pellets with a high sintered density, excellent micro-homogeneity and good solubility in nitric acid. Liquid wastes showed a very low content of actinides and the process is easy to operate in a glove box environment. The microwave direct denitration was optimized with uranium alone and the conditions to obtain high density pellets, with a good microstructure, without using a milling step, have been developed. At present, new experiments are being carried out to improve the reverse strike co-precipitation process and direct microwave denitration. A new glove box is being installed at the plutonium laboratory, this glove box has process equipment designed to recover scrap from previous fabrication campaigns, and to co-convert mixed U-Pu solutions by direct microwave denitration.

  14. Effect of solvent on in vitro dissolution: Summary of results for uranium, americium, and cobalt aerosols

    International Nuclear Information System (INIS)

    The revised 10 CFR Part 20 has adopted the ICRP Publication 30 method for calculating the committed effective dose equivalent from intakes of radionuclides. This dosimetry scheme requires knowledge or assumptions about the chemical form of the radionuclide, its particle size, and its known or assumed solubility. The solubility is classified as being either D (relatively soluble), W, or Y (relatively insoluble), depending on whether the material dissolves over periods of days, weeks, or years. Although Nuclear Regulatory Commission licensees may wish to take advantage of material-specific knowledge in order to adjust annual limits on intake and derived air concentrations, relatively few radioactive materials to which workers and the general population may be exposed have been adequately characterized either in terms of physicochemical form or solubility. Experimental measurement of solubility using some type of in vitro dissolution measurement system is therefore needed. However, there is currently no clear consensus regarding the appropriate design of in vitro dissolution systems, particularly when considering the range of different radionuclides to be studied, and the complexity of the biological mechanisms involved in the retention and clearance of inhaled deposited radioactive particles. The purpose of this study was to evaluate the effect of the several solvents on the dissolution of four test aerosols (57Co3O4, 241AmO2, ammonium diuranate [ADU], and U3O8) selected to encompass a variety of chemical and biochemical properties in vivo. The results of this study provide some guidance on the usefulness of in vitro dissolution tests for estimating the solubility of unknown radionuclide particles within the context of a simple model such as the class D, W, and Y formulation of ICRP 30

  18. Development of advanced LWR fuel pellet technology

    International Nuclear Information System (INIS)

    A UO2 pellet was designed to have a grain size of larger than 12 μm, and a new duplex design that UO2-Gd2O3 is in the core and UO2-Er2O3 in the periphery was proposed. A master mixing method was developed to make a uniform mixture of UO2 and additives. The open porosity of UO2 pellet was reduced by only mixing AUC-UO2 powder with ADU-UO2 or milled powder. Duplex compaction tools (die and punch) were designed and fabricated, and duplex compacting procedures were developed to fabricate the duplex BA pellet. In UO2 sintering, the relations between sintering variables (additive, sintering gas, sintering temperature) and pellet properties (density, grain size, pore size) were experimentally found. The UO2-U3O8 powder which is inherently not sinterable to high density could be sintered well with the aid of additives. U3O8 single crystals were added to UO2 powder, and homogeneous powder mixture was pressed and sintered in a reducing atmosphere. This technology leads to a large-grained pellet of 12-20 μm. In UO2-Gd2O3 sintering, the relations between sintering variables (additives, sintering gas) and pellet properties (density, grain size) were experimentally found. The developed technology of fabricating a large-grained UO2 pellet has been optimized in a lab scale. Pellet properties were investigated in the fields of (1) creep properties, (2) thermal properties, (3) O/M ratios and (4) unit cell lattice. (author)

  19. Electrochemical decontamination of metallic waste contaminated with uranium compounds

    International Nuclear Information System (INIS)

    A study on the electrolytic dissolution of SUS-304 and Inconel-600 specimen was carried out in neutral salt electrolyte to evaluate the applicability of electrochemical decontamination process for recycle ro self disposal with authorization of large amount of metallic wastes contamination with uranium compounds generated by dismantling a retired uranium conversion plant in Korea. Although the best electrolytic dissolution performance for the specimens was observed in a Na2SO4 electrolyte, a Na3NO3 neutral salt electrolyte, in which about 30% for SUS-304 and the same for Inconel-600 in the weight loss was shown in comparison with that in Na2 SO4 solution, was selected as an electrolyte for the electrochemical decontamination of metallic wastes with the consideration on the surface of system components contacted with nitric acid and the compatibility with lagoon wastes generated during the facility operation. The effects of current density, electrolytic dissolution time, and concentration of NaNO3 on the electrolytic dissolution of the specimens were investigated. On the basis of the results obtained through the basic inactive experiments, electrochemical decontamination tests using the specimens contaminated with uranium compounds such as UO2, AUC (ammonium uranyl carbonate) and ADU (ammonium diuranate) taken from an uranium conversion facility were performed in 1M NaNO3 solution with the current density of 100 mA/cm2. It was verified that the electrochemical decontamination of the metallic wastes contaminated uranium compounds was quite successful in a NaNO3 neutral salt electrolyte by reducing α and β radioactivities below the level of self disposal within 10 minutes regardless of the type of contaminants and the degree of contamination.

  20. Decommissioning of nuclear fuel cycle facilities - IPEN's experience

    International Nuclear Information System (INIS)

    Since its foundation in 1956, IPEN has played a decisive role in the development of the nuclear science and technology in Brazil. As an evidence of the multidisciplinary character of the scientific and technological work being carried out at IPEN/CNEN-SP could be mentioned activities such as radioisotope production, nuclear radiation applications, nuclear reactors, materials science, nuclear fuel cycle, radiological safety and dosimetry, laser applications, biotechnology, materials, chemical processes and environment. The Institute recent history has shown a major participation in the technological development of all steps of the nuclear fuel cycle. Fuel cycle activities were accomplished in pilot plant scale and most facilities were built in the 70-80 years. The facilities were used to promote human resources, scientific research and better understanding of fuel cycle technologies. Nevertheless, radical changes of the Brazilian nuclear policy in the beginning of 90's determined the interruption of activities and facilities shutdown. The problem of dismantling and decommissioning of deactivated facilities has been target of concern at IPEN considering that there was no experience/expertise in this field at all. Two facilities were actually dismantled at IPEN recently. On one hand there is the problem of facilities maintenance/surveillance. On the other hand there are the usual lack of resources and different problems involving each facility such as documentation, planning, risk assessment, decommissioning cost estimating, selection of dismantling techniques, decontamination costs x waste disposal, decontamination techniques, extent of decontamination, availability of waste disposal space, safety and staff training among others. However, in spite of the mentioned problems, a team has already dismantled two pilot plants: ADU (impure) dissolution / uranyl nitrate purification and part of the thorium nitrate (mantle grade) production. In this work, besides a small

    X-ray radiography is an important and frequently used NDE method of testing metal structures, such as tube welding quality, cracks and voids in cast iron or other metals. It gives fast and visible answer for structural defects. The Varian high energy portal imagers on Clinacs used in cancer treatment were tested for this purpose. We compared the traditional Gadox (LANEX) screen with and without a 1mm Cu buildup plate as used clinically. We also tested different hybrid scintillators, which consisted of different phosphor layers deposited onto fiberoptic plates. The last screen tested was a 2cm thick fiberoptic plate which contained scintillating fibers. The sensitivity (ADU = number of digital counts per a given X-ray dose), the resolution (MTF - modulation transfer function) and the DQE (detective quantum efficiency) were compared, with a 1 MV source, for these X-ray conversion screens. We found that the additional 1mm Cu plate, which improves the absorption and the contrast at 6 or higher energy MeV imaging, does not improve the image quality at 1MV. Rather it attenuates the X-rays, resulting in lower sensitivity and a lower DQE(0) of 2.2% with the additional Cu plate compared to DQE(0) of ~4% without the Cu plate. The hybrid scintillators with evaporated phosphors on fiberoptic plates tested were too thin resulting in low sensitivity. The best results were obtained from the thick scintillating fiberoptic screens, which provided the best DQE and high resolution with the 1MV X-ray beam. Further optimization is planned by changing the thickness of the scintillating fiber optic plate.

    2013-06-11

    Ion exchange using spherical resorcinol-formaldehyde (SRF) resin has been selected by the U.S. Department of Energy’s Office of River Protection (DOE-ORP) for use in the Pretreatment Facility (PTF) of the Hanford Tank Waste Treatment and Immobilization Plant (WTP) and for potential application in at-tank deployment. Numerous studies have shown SRF resin to be effective for removing 137Cs from a wide variety of actual and simulated tank waste supernatants (Adamson et al. 2006; Blanchard et al. 2008; Burgeson et al. 2004; Duignan and Nash 2009; Fiskum et al. 2006a; Fiskum et al. 2006b; Fiskum et al. 2006c; Fiskum et al. 2007; Hassan and Adu-Wusu 2003; King et al. 2004; Nash et al. 2006). Prior work at the Pacific Northwest National Laboratory (PNNL) has focused primarily on the loading behavior for 4 to 6 M Na solutions at 25 to 45°C. Recent proposed changes to the WTP ion exchange process baseline indicate that loading may include a broader range of sodium molarities (0.1 to 8 M) and higher temperatures (50°C) to alleviate post-filtration precipitation issues. This report discusses ion exchange loading kinetics testing activities performed in accordance with Test Plan TP-WTPSP-002, Rev. 3.0 , which was prepared and approved in response to the Test Specification 24590 PTF-TSP-RT-09-002, Rev. 0 (Lehrman 2010) and Test Exception 24590 PTF TEF RT-11-00003, Rev. 0 (Meehan 2011). This testing focused on column tests evaluating the impact of elevated temperature on resin degradation over an extended period of time and batch contacts evaluating the impact on Cs loading over a broad range of sodium concentrations (0.1 to 5 M). These changes may be required to alleviate post-filtration precipitation issues and broaden the data range of SRF resin loading under the conditions expected with the new equipment and process changes.

  5. Crustal structure of the western transect of the Rif Cordillera from broadband magnetotelluric data

    International Nuclear Information System (INIS)

    Complete text of publication follows. Within the frame of the Topo-Iberia project, the magnetotelluric method has been applied for first time in the western transect of the Rif Cordillera to delineate the electrical crustal structure. Data acquisition has been done in 18 MT measurement sites, with ADU-07 Metronix equipment, including vertical magnetic records. Frequencies range from 4Hz to 32 kHz and acquisition time on each site was from two to three days. The profile extends approximately 110 km in NE-SW trend orthogonal to the main regional geological structures, crossing from the Alboran Sea coast through the major alpine units of the western Rif Cordillera up to the foreland Gharb basin. We have performed a dimensionality analysis using the Wal's and the Bahr's methods, both based on the rotational invariants. The data obtained show variable dimensionalities ranging from 1D to 3D. Predominant strikes suggest NW-SE orientations. Therefore several 2D models have processed using Winglink software with different rotations. The model with N145 deg E rotation shows a good correlation between the resistive structures and the surface geology, as well as their continuity in depth. The Internal Zones corresponds generally to resistive rocks (metamorphic rocks) including a significant conductive body that probably corresponds to the nearby outcropping Beni Boussera peridotites. The External Zones and the foreland basin are characterized by shallow heterogeneous conductive structures. In depth, the most relevant feature corresponds to a large resistive body located below the frontal part of the Rif. The presence of exotic gneiss blocks in the front of the External Zones suggests that this large deep body may correspond to a gneissic or granitic basement surrounded by metapelitic rocks. The deep structure of this transect contributes to highlight the recent evolution and development of the southern part of the Gibraltar Arch in the frame of the Eurasian-African convergent

  6. Effect of solvent on in vitro dissolution: Summary of results for uranium, americium, and cobalt aerosols

    1995-12-01

    The revised 10 CFR Part 20 has adopted the ICRP Publication 30 method for calculating the committed effective dose equivalent from intakes of radionuclides. This dosimetry scheme requires knowledge or assumptions about the chemical form of the radionuclide, its particle size, and its known or assumed solubility. The solubility is classified as being either D (relatively soluble), W, or Y (relatively insoluble), depending on whether the material dissolves over periods of days, weeks, or years. Although Nuclear Regulatory Commission licensees may wish to take advantage of material-specific knowledge in order to adjust annual limits on intake and derived air concentrations, relatively few radioactive materials to which workers and the general population may be exposed have been adequately characterized either in terms of physicochemical form or solubility. Experimental measurement of solubility using some type of in vitro dissolution measurement system is therefore needed. However, there is currently no clear consensus regarding the appropriate design of in vitro dissolution systems, particularly when considering the range of different radionuclides to be studied, and the complexity of the biological mechanisms involved in the retention and clearance of inhaled deposited radioactive particles. The purpose of this study was to evaluate the effect of the several solvents on the dissolution of four test aerosols ({sup 57}Co{sub 3}O{sub 4}, {sup 241}AmO{sub 2}, ammonium diuranate [ADU], and U{sub 3}O{sub 8}) selected to encompass a variety of chemical and biochemical properties in vivo. The results of this study provide some guidance on the usefulness of in vitro dissolution tests for estimating the solubility of unknown radionuclide particles within the context of a simple model such as the class D, W, and Y formulation of ICRP 30.

  8. Production of nuclear ceramic fuel for nuclear power plants at 'Ulba metallurgical plant' OSC

    International Nuclear Information System (INIS)

    The paper describes the flow-sheet of production of uranium dioxide powders and nuclear ceramic fuel pellets of them existing at the facility. 'UMP' OSC applies ADU extraction process of UO2 powders production. An indisputable success of the process is the possibility of use of the wide range of raw materials. Uranium hexafluoride, uranium oxides, uranium metal, uranium tetrafluoride, uranyl salts, uranium ore concentrates, all possible types of uranium-containing materials the processing of which by routine methods is difficult (ashes, scraps, etc.) are used as the raw materials. In addition, a reprocessed nuclear fuel can be used for fuel production. The quality of uranium dioxide powder produced does not depend on the type of uranium raw material used. High selectivity of extraction refining makes possible to obtain material with rather low impurities content that meets practically all specifications for uranium dioxide known to us. Ceramic and process features of uranium dioxide powders, namely, specific surface, bulk density, grain size and sinterability make possible to produce nuclear ceramic fuel with specified features. Quality of uranium dioxide powders produced by 'UMP' OSC was highly rated by General Electric company that is one of the leading companies from fuel manufactures in the USA market . It has certified 'UMP' OSC as its supplier. Currently, our company makes great efforts on establishing production of uranium dioxide powders with natural isotopes content for production of fuel for CANDU reactors. Trial lots of such powders are under tests at some companies manufacturing fuel for this type reactors in Canada, USA and Corea

    The CANDU-type nuclear fuel localization project started in 1981, and mass-production system completed in 1987 through the pilot scale demonstration of fuel manufacturing. Since the completion of the mass-production system, about 24,000 fuel bundles (450 ton-U) had been delivered to Wolsung Nuclear Power Plant by the end of 1992, according to the fuel supply contracts with KEPCO. The superiority of KAERI-made nuclear fuel has been demonstrated by having achieved the highest utilization factor in the world in 1992. In 1993, as contracted, 4,824 fuel bundles well fabricated and delivered to Wolsung Nuclear Power Plant. The process improvement, quality control, safety management, safeguards of nuclear materials and various kinds of audits have also been performed in the course for fuel manufacturing. Especially in 1993, the difficulties of the reduction of participating work-force were overcome by improving the manufacturing techniques, and raising the efficiency of the works, which eventually lead to the reduction of production cost. The major improvements achieved are as follows ; 1. Improvement of the fuel pellet productivity In spite of the additional powder treatment process due to the use of the UO{sub 2}-exADU instead of UO{sub 2}-exAUC, the daily production of 800 kg.UO{sub 2} which is the 60% extension in the productivity, can be achieved by improving slugging process and blending process. 2. Improvement of fuel rod fabrication process The productivity of rod fabrication can be doubled by improving the pellet loading equipment. 3. Other production supporting activities In the year of 1993, trend analysis of the product qualities, physical inventory verification of nuclear materials, QA/QC audits, annual facility inspection and product shipping inspections have been performed by IAEA, MOST, KINS and KEPCO to ensure the quality and safety of the nuclear fuel and the facility.

  13. MT soundings in south Shetland Islands and Antarctic Peninsula (Antarctica). Constraints to the crustal structure of the Bransfield strait conjugated continental margins

    International Nuclear Information System (INIS)

    Complete text of publication follows. The South Shetland Block was separated from the Antarctic Peninsula during the opening of the Bransfield Strait since the Pliocene (about 3.3 Ma). The Bransfield basin is developed by the interaction of two tectonic processes that continue active up to Present: the back-arc extension related to the subduction of the former Phoenix plate oceanic crust along the South Shetland trench and the transtensional deformation associated to the western end of the sinistral Scotia-Antarctic plate boundary along the South Scotia Ridge fault zone. In this tectonic framework 12 MT broadband data (BBMT) were recorded along a NW-SE transect orthogonal to the Bransfield Strait, with Metronix ADU-06 equipments, during 2008 and 2009 International Polar Year field surveys. Due to the difficult access of the region and in order to compare the resistivity crustal features, MT soundings were grouped in three sectors representing the different tectonic settings. In the South Shetland Block 4 MT soundings were located in Livingston Island (3 in Byers Peninsula and one in Hurd Peninsula) and suggest the presence of conductive Cretaceous to Cenozoic sedimentary and volcanic rocks above the resistive and heterogeneous metamorphic basement that outcrop in Hurd Peninsula. Southwards, 7 MT sounding were situated around the Quaternary volcanic caldera of Deception Island, formed on the fault system separating the South Shetland Block and the Bransfield basin. Conductive bodies highlight the location of the main magma chambers. Finally, in the Antarctic Peninsula northern margin a MT sounding was obtained in Isla Larga, near the O'Higgins base that constitutes one of the scarce islands of this region not covered by ice during the summer. This MT sounding suggest a 3D complex resistivity structure related to the metamorphic rocks intruded by basic dykes. These MT soundings may contribute to improve the scarce available data on the crustal structure of this

    to the broader considerations related to uncertainty of the proposed method's measurements, due to the authors' awareness that this is the first prototype of such a device and, on the basis of this experience, another one will be built and tested. The observations and numerical analysis of the image formed on the screen by the passage of a laser beam through the free surface of the liquid-gas separation show that at low values of pressure difference, the bubble acts as a membrane shifting in the direction of lower pressure, in such way that the displacement is proportional to the pressure difference at both ends of the bubble. The proprietary method of numerical data processing presented in this article, based on analysis of the intensity of color change in a frame moving along a selected line outside of visual changes in the image of the laser beam after passing through the test structure, provided a tool to create first mathematical models to describe the observed changes (2),(3). Presented in this article method of measuring the difference between the free surface levels in two containers, and hence the measurement of hydrostatic pressure difference provides a new tool for laboratory measurements in the fields of science, which were previously unattainable.

    cells: those which axons form the ipsolateral abducens nerve and those (interneurons whose axons reach the medial longitudinal fasciculus and ascend for innervating the subnucleus of the contralateral III nerve subserving the contralateral medial rectus. Because of this arrangement, a lesion at the region of the VI nerve nucleus generally causes a paralysis of the ipsolateral lateral rectus and the contralateral medial rectus muscles, which characterizes the ipsolateral horizontal gaze palsy. CONCLUSION: The definition of the Möbius sequence is the paralysis of the facial nerve and the horizontal gaze palsy, instead of a VI nerve palsy, as seen in most published papers.OBJETIVO: Não há uniformidade na literatura sobre as anomalias necessárias para caracterizar a seqüência de Möbius. Originalmente, os requisitos mínimos eram a paralisia do VI e do VII nervos cranianos. A paralisia facial bilateral, às vezes assimétrica, é comum a todos os pacientes, mas alguns fatos mostram que a paralisia isolada do VI nervo não é a regra.1 Quando há esotropia na seqüência de Möbius, é muitas vezes muito pequena para ser causada por paralisia bilateral do VI nervo. Há muitos casos que não apresentam esotropia ou mesmo, embora raramente, têm exotropia. 2 Em muitos casos a esotropia pode ser eliminada com apenas o retrocesso dos retos mediais. 3 Em muitos desses pacientes há, além da limitação de abdução, também limitação de adução, o que define a paralisia conjugada dos movimentos horizontais. Os autores apresentam argumentos para mostrar que a paralisia isolada dos retos laterais não pode ser considerada condição sine qua non para o diagnóstico da seqüência de Möbius. MÉTODOS: O alinhamento binocular em posição primária e a incidência de limitação de abdução e adução entre 28 dos casos consecutivos de seqüência de Möbius dos autores e entre os casos de 5 outros autores eleitos aleatoriamente são apresentados para coment

    Full Text Available A distonia laríngea respiratória (DLR é uma desordem rara caracterizada por espasmos da musculatura adutora das pregas vocais durante a fase inalatória da respiração, com manifestação clínica de dispnéia e estridor. O diagnóstico etiológico do estridor laríngeo, entretanto, nem sempre é fácil de ser realizado, principalmente em situações emergenciais, de forma que a DLR pode não ser diagnosticada, o que nos leva a supor ser mais freqüente do que usualmente é descrita. O diagnóstico da DRL requer primeiramente a realização de uma história médica e exames laringológico e neurológico apropriados, com ênfase na verificação da presença de características distônicas e na exclusão de outras etiologias causadoras de movimentos paradoxais de pregas vocais. Muitos tratamentos foram propostos para a DLR, mas nenhum deles apresentou resultados satisfatórios. O uso da Toxina Botulínica do tipo A (Botox® no músculo tireoaritenoídeo tem oferecido melhoras admiráveis, apesar dos poucos casos descritos. Apresentamos dois casos clínicos de pacientes com DLR tratados com Botox® que apresentavam o fechamento glótico inspiratório causado tanto pelos espasmos anômalos dos músculos tireoaritenoídeos, como pela movimentação paradoxal da epiglote. Dentro da classificação proposta por Koufman e Blabock para as distonias laríngeas, inserimos um novo subtipo de DLR caracterizado pela presença de paroxismos de adução de estruturas glóticas e supraglóticas durante a respiração.

  18. A custom on-line ultrasonic gas mixture analyzer with simultaneous flowmetry developed for use in the LHC-ATLAS experiment, with wide application in high and low flow gas delivery systems

    International Nuclear Information System (INIS)

    We describe a combined ultrasonic instrument for continuous gas flow measurement and simultaneous real-time binary gas mixture analysis. In the instrument, sound bursts are transmitted in opposite directions, which may be aligned with the gas flow path or at an angle to it, the latter configuration being the best adapted to high flow rates. Custom electronics based on Microchip R dsPIC and ADuC847 micro-controllers transmits 50 kHz ultrasound pulses and measures transit times in the two directions together with the process gas temperature and pressure. The combined flow measurement and mixture analysis algorithm exploits the phenomenon whereby the sound velocity in a binary gas mixture at known temperature and pressure is a unique function of the molar concentration of the two components. The instrument is central to a possible upgrade to the present ATLAS silicon tracker cooling system in which octafluoro-propane (C3F8) evaporative cooling fluid would be replaced by a blend containing up to 25% hexafluoro-ethane (C2F6). Such a blend will allow a lower evaporation temperature and will afford the tracker silicon substrates a better safety margin against leakage current-induced thermal runaway caused by cumulative radiation damage as the luminosity profile at the CERN Large Hadron Collider (LHC) increases. The instrument has been developed in two geometries following computational fluid dynamics studies of various mechanical layouts. An instrument with 45 crossing angle has been built in stainless steel and installed for commissioning in the ATLAS silicon tracker evaporative fluorocarbon cooling system. It can be used in gas flows up to 20000 l.min-1, and has demonstrated a flow resolution of 2.3% of full scale for linear flow velocities up to 10 m.s-1 in preliminary studies with air. Other instruments are currently used to detect low levels of C3F8 vapour leaking into the N2 environmental gas surrounding the ATLAS silicon tracker. Gas from several parts of the

  20. Large grain size UO2 sintered pellets obtaining used for burn up extension

    International Nuclear Information System (INIS)

    The actual tendency all over the world is to manufacture fuel bundles capable to resist high burn-up. The main factors affecting the burn-up increase are: the pellet-cladding mechanical interaction (PCMI), the oxidation and hydriding of the Zircaloy-4 sheath, the increase of internal pressure, stress corrosion cracking, Zircaloy-4 irradiation growth, fuel swelling. A way to increase fuel burn-up is to diminish the elements internal pressure by an adequate large grain UO2 fuel pellet structure. In the large grain size UO2 pellets, fission gas release rate decreases and the elements internal pressure increase slowly. One of the ways to increase pellets grain size without increasing sintering temperature and time is the addition of small quantities (2 powder (TiO2, Nb2O5, Cr2O3, CaO, V2O5), the grain size, the porosity and the mean free diffusion path are increased, whereas the grain boundary area is reduced. At the Institute for Nuclear Research (ICN) at Pitesti a project for obtaining large grains size UO2 pellets using dopants was developed. Two UO2 non-free flowing powders, manufactured by ADU and IDR routes, were mixed with dopants (TiO2, Nb2O5, Cr2O3), content of metals being 0.05-1 % wt M/U. The green pellets obtained by pressing UO2 powders were directly sintered (4 hours at 1700 degC) in a sintering furnace. The physical, mechanical and microstructural properties of UO2 sintered pellets with large grain size are studied, as compared to the undoped ones. The diagrams presented the dependency of the main sintered pellet characteristics (pore radius distribution, pores volume, density, grains size) as function of the dopant nature and concentration, UO2 sinterable powder nature and sintering temperature. Other sintered pellets characteristics (electrical conductivity, Seebeck coefficient, high temperature molar heat capacity and thermomechanical properties) are important to study. The beneficial effects resulted from theoretical and practical projects are

  2. Core Material Preparation of TRISO Coated Particle in HTGR Fuel

    International Nuclear Information System (INIS)

    A VHTR(Very High Temperature Reactor) is being conducted by many countries mainly promoted for electricity production and high temperature process heat. The proposed nuclear fuel for the preliminary reactor concept on these purposes is a TRISO(Tri-Isotropic or multi-layered structure) coated particle prepared by pyro-carbon and silicone coatings on a spherical UO2 kernel surface as a fissile material. Generally, UO2 kernels are prepared by using the modified sol-gel process, wet process, known as the GSP(gel supported precipitation) method. This chemical route was well-known to the potential kernel fabrication process. HTGR nuclear fuel production processes have been classified in five categories of research and development : - Spherical UO2 kernel preparation step - Pyro-carbon(PyC) and silicon carbide(SiC) coatings - Pebble or Prismatic block preparation by using graphite matrix powder - Fuel performance including a fission products release - Advanced and improved fuel development The well-known GSP process is one of the modified processes for an external gelation method developed NUKEM of Germany. As shown in Figure 1, a spherical UO2 kernel particle was prepared by using a modified external gelation process. UO2 kernels are highly dense sintered microsphere of stoichiometric UO2 with a nominal diameter of about 500 μm. The raw material for UO2 kernel preparation is nuclear grade U3O8 powder which will be dissolved with nitric acid to obtain the UN solution. The procedures are formed by mixing the UN solution with organic additives and transferring the aqueous solution to spherical droplets, which are on the surface of liquid droplets slightly hardened by a chemical reaction with ammonia. The necessary viscosity and shape of liquid droplets are achieved by the addition of PVA. THFA solution is added to achieve a controlled shrinkage of the ADU gel particles during gelation, ageing, and washing processes. After ageing in ammonia water and washing with demi

    The aim of the investigations was to estimate the half-life of selected PAHs in sewage sludge. Five hydrocarbons selected from 16 PAHs- EPA were chosen. In this study, the quantity changes in the concentration 3- and 4-ring of PAHs in sewage sludges were investigated. Sewage sludges were stored under aerobic conditions for 12 weeks. At the same time the sewage sludges with the added sodium azide, in order to deactivate the microorganisms (abiotic samples), were also stored. Gas chromatography-mass spectrometry was used to qualify and quantify PAHs in 2-week intervals. Sewage sludges were taken from a municipal wastewater treatment plant. Under experimental conditions the half-lives of individual compounds were diversed. In biotic samples halflife of hydrocarbons was in the range of 19 to 368 days. Half-life of PAHs in abiotic sewage sludges was in the range of 31 to 2961 days. The most persistent were phenanthrene. Celem badań była ocena trwałości WWA w warunkach składowania poprzez wyznaczenie czasu połowicznego rozpadu. Określono zmiany ilościowe WWA w osadach przechowywanych w warunkach tlenowych przez 12 tygodni. W tych samych warunkach pozostawały także osady, w których zahamowano aktywność mikroorganizmów poprzez dodatek azydku sodu. Ilościową analizę WWA prowadzono z wykorzystaniem zestawu GC-MS w odstępach 2-tygodniowych równolegle w osadach biotycznych i abiotycznych. Oznaczano pięć WWA (fluoren, fenentren, antracen, fluoranten, piren), które znajdują się wśród 16 związków podanych na liście EPA. Osady pobrano dwukrotnie z oczyszczalni ścieków komunalnych, które w praktyce kierowane są na składowisko. Zawartość początkowa WWA w osadach była na poziomie 346μg/kg.s.m. W warunkach prowadzonego eksperymentu czas połowicznego rozkładu był zróżnicowany dla poszczególnych związków. W osadach aktywnych biologicznie czas połowicznego rozpadu badanych węglowodorów był w granicach od 19 do 368 dób. Czas po

    Ion exchange using spherical resorcinol-formaldehyde (SRF) resin has been selected by the U.S. Department of Energy’s Office of River Protection (DOE-ORP) for use in the Pretreatment Facility (PTF) of the Hanford Tank Waste Treatment and Immobilization Plant (WTP) and for potential application in at-tank deployment. Numerous studies have shown SRF resin to be effective for removing 137Cs from a wide variety of actual and simulated tank waste supernatants (Adamson et al. 2006; Blanchard et al. 2008; Burgeson et al. 2004; Duignan and Nash 2009; Fiskum et al. 2006a; Fiskum et al. 2006b; Fiskum et al. 2006c; Fiskum et al. 2007; Hassan and Adu-Wusu 2003; King et al. 2004; Nash et al. 2006). Prior work at the Pacific Northwest National Laboratory (PNNL) has focused primarily on the loading behavior for 4 to 6 M Na solutions at 25 to 45°C. Recent proposed changes to the WTP ion exchange process baseline indicate that loading may include a broader range of sodium molarities (0.1 to 8 M) and higher temperatures (50°C) to alleviate post-filtration precipitation issues. This report discusses ion exchange loading kinetics testing activities performed in accordance with Test Plan TP-WTPSP-002, Rev. 3.01, which was prepared and approved in response to the Test Specification 24590-PTF-TSP-RT-09-002, Rev. 0 (Lehrman 2010) and Test Exception 24590-PTF-TEF-RT-11-00003, Rev. 0 (Meehan 2011). This testing focused on column tests evaluating the impact of elevated temperature on resin degradation over an extended period of time and batch contacts evaluating the impact on Cs loading over a broad range of sodium concentrations (0.1 to 5 M). These changes may be required to alleviate post-filtration precipitation issues and broaden the data range of SRF resin loading under the conditions expected with the new equipment and process changes.

Widespread vascular endothelial cell dysfunction is thought to mediate the generalized vasospasm and hypertension characteristic of PE. Altered nitric oxide (NO production has been associated with the endothelial dysfunction in the pathogenesis of PE but conflicting results have emerged from previous studies. Objectives: To determine maternal serum levels of NO, a biomarker of endothelial function, in nonpregnant, normal pregnant, and preeclamptic women. Materials and methods: This was a cross-sectional case–control study of 277 women comprising 75 nonpregnant, 102 normal pregnant, and 100 preeclamptic women conducted at the Korle Bu Teaching Hospital between April and June 2011. About 5 mL of venous blood was obtained from the participants for the various investigations after meeting the inclusion criteria and signing to a written consent. Serum levels of NO were determined by Griess reaction. The data obtained were analyzed with SPSS version 20. Results: The study showed significantly elevated serum levels of NO in preeclamptic women (82.45±50.31 µM compared with normal pregnant (33.12±17.81 µM and nonpregnant (16.92±11.41 µM women with P<0.001. The alteration in maternal serum NO levels was significantly more profound in early-onset (severe PE (119.63±45.860 µM compared to that of late-onset (mild disease (62.44±40.44 µM with P<0.001, indicating a more severe vascular endothelial cell dysfunction in the

Biorąc jednakże pod uwagę fi zykalną naturę procesu pomiaru można zauważyć, że projektowane dodatkowe obserwacje mogą zwiększyć liczbę potencjalnych błędów grubych w sieci, nie podnosząc niezawodności wewnętrznej do oczekiwanego według teorii poziomu. Niezbędne jest zatem ustalenie realistycznych poziomów górnych dla liczby obserwacji w sieci. W niniejszym artykule podjęta jest próba sformułowania zasad ustalania takich poziomów.

Przy użyciu pomocniczej zależności wyprowadzonej na podstawie gaussowskiego rozkładu błędów dokonano modyfikacji formuły Adamczewskiego, przekształcając ją w jawną funkcję liczby obserwacji w sieci. Umożliwiło to skonstruowanie narzędzi niezbędnych do analizy, i ostatecznie sformułowanie wskazań co do wyznaczania górnych limitów niezawodności wewnętrznej sieci.

    It is well known that in LHCD system, the rf power coupling between antenna and plasma strongly depends on the edge plasma parameter. Thus it is mandatory to monitor edge plasma parameter to establish proper impedance matching condition when LHCD power is launched into the plasma. For SST1 LHCD system, we intend to monitor the edge plasma parameter employing electric probes, connected to the grill antenna sides for the said purpose. In SST1, initially LHCD system would couple rf power to plasmas lasting for small durations. Gradually the power and pulse length would be increased to eventually get 1000 seconds plasma. To monitor the edge plasma parameter, over such a wide spectrum (say few millisecond to seconds) during the above campaign, a flexible measurement scheme is desired which would cater to entire spectrum of operation. Normally a ramp is utilized to bias the electric probe, which yields various plasma parameters. To cater our requirement, the ramp generator must have facility to change ramp-up rate to meet our pulse length requirement. Further during SST operation, the human access near the machine would not be permitted and ramp circuit might not be accessible for manual settings. Thus remote setting facility to change ramp-up rate is also desired. Keeping these constraints in mind, a ramp circuit has been designed using Analog Device micro-controller ADuC842. The circuit has both manual and remote setting facility. Ramp generator parameters like Ramp-up rate, Trigger mode, number of cycles, etc. can be set from PC through RS-485 serial link. Initially low voltage (0-5V) ramp signal is generated using micro-controller and inbuilt DAC. This low voltage ramp is then amplified with PA-85 op-amp to get desired probe biasing voltage (-110V to +110V). The ramp period can be change form (1ms to 1000 ms) to cater to different plasma pulse length. Programming for micro-controller is done in structured language-C with the help of "Keil" IDE.

    Superoxide dismutase (SOD, EC 1.15.1.1) plays a key role in response to drought stress, and differences in SOD activity changes among cultivars are important under drought conditions. We obtained the full-length DNA of the chloroplast Cu/Zn-SOD gene (AhCSD2) from 11 allotetraploid cultivars and 5 diploid wild species in peanut. BLAST search against the peanut genome showed that the AhCSD2 genes gCSD2-1 and gCSD2-2 are located at the tops of chromosome A03 (A genome) and B03 (B genome), respectively, and both contain 8 exons and 7 introns. Nucleotide sequence analyses indicated that gCSD2-2 sequences were identical among all the tested cultivars, while gCSD2-1 sequences showed allelic variations. The amino acid sequences deduced from gCSD2-1 and gCSD2-2 both contain a chloroplast transit peptide and are distinguished by 6 amino acid (aa) residue differences. The other 2 aa residue variations in the mature peptide regions give rise to three-dimensional structure changes of the protein deduced from the genes gCSD2-1 and gCSD2-2. Sequences analyses of cultivars and wild species showed that gCSD2-2 of Arachis hypogaea and gAipCSD2 (Arachis ipaensis) are identical, and despite the abundant polymorphic loci between gCSD2-1 of A. hypogaea and sequences from A genome wild species, the deduced amino acid sequence of AhCSD2-1 (A. hypogaea) is identical to that of AduCSD2 (Arachis duranensis), whereas AcoCSD2 (Arachis correntina) and AcaCSD2 (Arachis cardenasii) both have 2 aa differences in the transit peptide region compared with AhCSD2-1 (A. hypogaea). Based on the Peanut Genome Project, promoter prediction revealed many stress-related cis-acting elements within the potential promoter regions (pp-A and pp-B). pp-A contains more binding sites for drought-associated transcriptional factors than pp-B. We hypothesize that the marked changes in SOD activity in different cultivars under drought stress are tightly regulated by transcription factors through transcription and

Cel pracy: Celem pracy było zbadanie w warunkach hodowli komórkowej aktywności jednojądrzastychkomórek krwi obwodowej (peripheral blood mononuclear cell – PBMC, po stymulacji progesteronemi 17β-estradiolem. Miarą aktywności PBMC było stężenie produkowanego przez te komórki transformującegoczynnika wzrostu beta (transforming growth factor β – TGF-β, który stanowi ważny czynnik biorący udział w regulacjii przebiegu cyklu menstruacyjnego i implantacji. Materiał i metody: Materiał do badań stanowiły PBMC izolowane z krwi 25 dawców. Uzyskane komórkihodowano przez 48 godz. w samym podłożu oraz w podłożu z dodatkiem różnych stężeń (1 ng/ml, 5 ng/ml,10 ng/ml progesteronu i 17β-estradiolu. Stężenie TGF-β w supernatancie z hodowli PBMC oznaczano metodąimmunoenzymatyczną ELISA (enzyme-linked immunosorbent assay. Wyniki: Analiza otrzymanych wyników wykazała, że po stymulacji zarówno progesteronem, jaki 17β-estradiolem, aktywność sekrecyjna PBMC zmieniała się. Wraz ze zwiększeniem stężenia progesteronu,stężenie TGF-β było istotnie statystycznie większe w porównaniu z hodowlą komórek niestymulowanych(p < 0,0001. Natomiast zwiększoną istotnie statystycznie sekrecję badanego parametru przez PBMC obserwowanodopiero po stymulacji komórek 17β-estradiolem o stężeniu 5 ng/ml (p < 0,0001. Wnioski: Progesteron i 17β-estradiol wykazują wpływ na aktywność PBMC. Zwiększoną aktywność tychkomórek obserwuje się po stymulacji większymi stężeniami hormonów, co znacznie wpływa na sekrecję TGF-β.

  12. ECR Plasma Photos

    International Nuclear Information System (INIS)

    Complete text of publication follows. In order to observe and study systematically the plasma of electron cyclotron resonance (ECR) ion sources (ECRIS) we made a high number of high-resolution visible light plasma photos and movies in the ATOMKI ECRIS Laboratory. This required building the ECR ion source into an open plasma device, temporarily. An 8MP digital camera was used to record photos of plasmas made from He, methane, N, O, Ne, Ar, Kr, Xe gases and from their mixtures. The effects of the main external setting parameters (gas pressure, gas composition, magnetic field, microwave power, microwave frequency) were studied to the shape, color and structure of the plasma. The double frequency mode (9+14 GHz) was also realized and photos of this special 'star-in-star' shape plasma were recorded. A study was performed to analyze and understand the color of the ECR plasmas. The analysis of the photo series gave us many qualitative and numerous valuable physical information on the nature of ECR plasmas. To our best knowledge our work is the first systematic study of ECR plasmas in the visible light region. When looking in the plasma chamber of an ECRIS we can see an axial image of the plasma (figure 1) in conformity with experimental setup. Most of the quantitative information was obtained through the summarised values of the Analogue Digital Unit (ADU) of pixels. By decreasing the strength of the magnetic trap we clearly observed that the brightness of the central part of the plasma gradually decreases, i.e. the plasma becomes more and more 'empty'. Figure 2 shows a photo series of ECR plasma at decreasing axial magnetic field. The radial size of the plasma increased because of the ascendant resonant zone. By increasing the power of the injected microwave an optimum (or at least saturation) was found in the brightness of the plasma. We found correlation between the gas dosing rates and plasma intensities. When sweeping the frequency of the microwave in a wide region

  14. Studies on the structure and problems of family poultry production in Tanzania

    International Nuclear Information System (INIS)

    In order to identify the major disease conditions and factors limiting family chicken production in Coast and Dar-es-Salaam regions of Tanzania a survey was undertaken in six villages in two zones involving a total of 43 households. Field data were collected through identified farmer interviews in the wet and dry seasons of 1999/2000. During farm visits, the birds were clinically examined, sick and dead ones autopsied. Blood smears, serum and faecal samples were collected for laboratory examination. There was significant variation in the flock size and structure in the interviewed households. The 43 households kept 1099 chickens with an average of 25.5 per household in the wet season while in the dry season the numbers were 1352 and an average of 31.4. The ratio of chicks:growers: aduIts was 10:10:14 in the wet season and 11:10:10 in the dry season. The cock:hen ratio was 1:3.5. Average numbers of clutches per year ranged from 2.80-3.02 (average 2-94). The average number of eggs per clutch was 12 and consequently the number of eggs was 36 per hen/year. Hatchability was recorded to be 84.5. Chick mortality was found to be 30% and resulted mainly from diseases and predation. Out of 43 households interviewed, 23 kept their chickens in the chicken house, 12 within the family house, four in the kitchen/store, three kept their birds perched in trees and one used a woven basket. In all the households, scavenging was the system of feeding and sometimes supplemented by household scraps and other feeds. Poultry movement into the household's flocks resulting in mixing of birds from different flocks was rampant. Several diseases and in particular Newcastle disease were mentioned by farmers in both zones as the major constraints restricting rural chicken development. Other diseases included coughing/sneezing, fowl pox and parasitic diseases (helminths, external parasites, protozoa). Women played a major role in family poultry development through provision of labour, but men

    ę sklepienia ciśnień (Sałustowicz, 1956). Teoria ta znakomicie nadaje się do tego celu, gdyż jako jedyna z wielu w tym zakresie pozwala określić, czy pustka związana z wyrobiskiem znajduje się w stanie stateczności. Znane są bowiem przypadki, gdy płytkie wyrobiska górnicze, bez obudowy przez wiele lat pozostają w stanie nienaruszonym. W ramach pracy dokonano szczegółowych obliczeń pola strefy odprężonej nad wyrobiskiem, bez stosowania uproszczeń przyjętych przez autora metody. Stosując podobne założenia jak w innych, znanych z literatury rozwiązaniach, podano warunki, mówiące o tym kiedy gruzowisko skalne zapełni szczelnie pustkę, bez powstania pustki wtórnej, a kiedy pustka wtórna powstanie. Zależy to od wymiarów i głębokości lokalizacji pustki oraz własności górotworu nad pustką. Warunkiem wystąpienia zapadliska jest aby strefa odprężona, związana z pustką pierwotną lub wtórną osiągnęła wysokość, przy której obejmować będzie nadkład, zbudowany ze skał luźnych. W dalszej kolejności zaproponowano wzory umożliwiające określenie wymiarów zapadlisk. Wyróżniono przy tym dwa przypadki: • gdy strop pustki osiąga spąg nadkładu - wzór (15), • gdy strefa odprężona obejmuje swym zasięgiem luźne skały nadkładu - wzór (19). Dalszym etapem badań prowadzonych przez autora jest sformułowanie warunków, pozwalających stwierdzić, kiedy eksploatacja górnicza prowadzona pod pustką może wywołać jej samopodsadzenie, a w konsekwencji spowodować powstanie zapadliska na powierzchni. Prowadzone są również prace związane z utworzeniem oprogramowania komputerowego, wykorzystującego podane wzory i z weryfikacją rozwiązania w oparciu o przypadki znane z praktyki górniczej.

Fig. 2 przedstawia koncepcję kombajnu jednoorganowego. Kombajn ten składa się z kadłuba 2, jednego zamocowanego centralnie organu urabiającego 1 oraz dwóch rozkładanych ładowarek odkładniowych 3 i 4. Ładowarka 3 znajduje się w pozycji czynnej, natomiast ładowarka 4 w biernej. Kombajn jest ciągnięty po rynnach przenośnika 5 za pomocą łańcucha 6. Łańcuch 7 jest gałęzią bierną dla przedstawionego zwrotu prędkości. Podane, orientacyjne wymiary wynikają z analizy dotychczasowych rozwiązań kombajnów, głowic strugowych oraz założonego zakresu wysokości wyrobiska ścianowego (Krauze, 2006; Bołoz, 2012). Dla zaproponowanego rozwiązania przyjęto szereg koniecznych wielkości i przeprowadzono analizę możliwego do uzyskania wydobycia dobowego. Zestawione tabelarycznie wyniki umożliwiają określenie wydobycia dobowego możliwego do uzyskania przy określonych wartościach parametrów geometrycznych ściany, kinematycznych kombajnu oraz organizacyjnych pracy ściany. Dla założonych parametrów można stwierdzić, że minimalne wydobycie dobowe na poziomie Vd = 4032 Mg/d uzyskano dla L = 180 m, tp = 11 min, H = 1.0 m oraz T = 12 h/d. Maksymalne wydobycie dobowe na poziomie Vd = 11 612 Mg/d uzyskać można dla L = 300 m, tp = 0 min, H = 1.6 m oraz T = 18 h/d. Na wydobycie dobowe największy wpływ ma dobowy czas pracy ściany a następnie czas przekładki (Bołoz, 2012). Średnica organu dla takiego kombajnu dobierana jest do grubości pokładu.

    to the broader considerations related to uncertainty of the proposed method's measurements, due to the authors' awareness that this is the first prototype of such a device and, on the basis of this experience, another one will be built and tested. The observations and numerical analysis of the image formed on the screen by the passage of a laser beam through the free surface of the liquid-gas separation show that at low values of pressure difference, the bubble acts as a membrane shifting in the direction of lower pressure, in such way that the displacement is proportional to the pressure difference at both ends of the bubble. The proprietary method of numerical data processing presented in this article, based on analysis of the intensity of color change in a frame moving along a selected line outside of visual changes in the image of the laser beam after passing through the test structure, provided a tool to create first mathematical models to describe the observed changes (2),(3). Presented in this article method of measuring the difference between the free surface levels in two containers, and hence the measurement of hydrostatic pressure difference provides a new tool for laboratory measurements in the fields of science, which were previously unattainable. Do poprawnego opisu przepływu płynu przez ośrodek porowaty niezbędna jest znajomość rozkładu ciśnienia. O ile dla dużych liczb Reynoldsa (przepływy turbulentne) pomiar ciśnienia dostępnymi na rynku przyrządami nie stanowi większego problemu, to dla przepływów laminarnych cieczy (tj. dla liczb Re (Bear, 1988; Duckworth, 1983; Troskolański, 1957) z zakresu 0.01 do 3) nie ma na rynku przyrządów o wystarczającej dokładności.

Opisano podstawowe zasady metody kompleksowej oceny stanu zagrożenia tąpnięciem, w skład której wchodzi metoda sejsmologiczna bieżącej (pomiarowej) oceny stanu zagrożenia. Od wielu lat, wraz z ciągłym rozwojem bazy aparaturowej i możliwości w zakresie cyfrowej rejestracji sejsmogramów oraz przetwarzania i interpretacji danych pomiarowych wzrasta znaczenie metod sejsmicznych, które są dzisiaj powszechnie stosowane w polskich kopalniach zagrożonych tąpaniami. Ciągła obserwacja zjawisk sejsmicznych indukowanych w trakcie rozwoju procesu eksploatacji pokładów węgla umożliwiła, w oparciu o zgromadzoną bazę danych, opracowywanie nowych kryteriów zagrożenia sejsmicznego oraz zagrożenia tąpnięciem, które winny wyraźnie poprawić efektywność metody sejsmologii górniczej. W artykule przedstawiono nowe kryteria oceny stanu bieżącego zagrożenia tąpaniami zaproponowane do stosowania w polskich kopalniach węgla kamiennego, które prowadzą eksploatację systemem ścianowym. Kryteria te są oparte na wynikach ciągłej rejestracji sejsmologicznej, połączonej z bieżącą analizą zarejestrowanych wstrząsów i obliczaniem wybranych parametrów sejsmologicznych. Parametry te to położenie ognisk wstrząsów w stosunku do wyrobisk eksploatacyjnych, energia sejsmiczna wstrząsów, suma energii sejsmicznej wyzwolona na każde 5m postępu ściany eksploatacyjnej, wartość wagowanego parametru amplitudy prędkości drgań PPVW, moment sejsmiczny M0, indeks energii EI oraz parametr b rozkładu wstrząsów według relacji Gutenberga-Richtera.

O exame neurológico evidenciou apenas prejuízo da adução e do olhar vertical para cima no olho direito, com discreta dilatação pupilar ipsilateral, sem ptose. RNM foi normal. A angiografia digital revelou dissecção da ACI direita com oclusão a montante até a base do crânio. A anticoagulação foi iniciada. A cefaléia e a movimentação ocular melhoraram em 3 semanas. DISCUSSÃO: A paralisia isolada do nervo oculomotor dificilmente é reconhecida como um possível sinal clínico de dissecção da ACI. Se o estudo angiográfico for incompleto, sem a avaliação cuidadosa das artérias extracranianas, esse diagnóstico deixa de ser feito, impedindo assim o início precoce da anticoagulação para a prevenção dos eventos tromboembólicos. Por isso, reforçamos a importância do estudo das artérias cervicais nos pacientes com paralisia do nervo oculomotor. A compressão mecânica ou o estiramento do nervo são mecanismos possíveis, mas o prejuízo direto do suprimento sanguíneo arterial para o nervo é a explicação mais plausível.

Essas informações podem futuramente ser empregada como ferramenta de apoio à decisão médica em ortopedia, fornecendo subsídios na escolha do procedimento cirúrgico. MÉTODOS: Método dos Elementos Finitos foi utilizado para construir um modelo biomecânico, tridimensional, da articulação do joelho. Nesse modelo com seis graus de liberdade é aplicado movimento de flexão/extensão sendo os demais cinco graus de liberdade governados pelas interações entre os componentes da articulares. RESULTADOS: Foram obtidas informações dos movimentos, das rotações interna/externa e adução/abdução, das translações anterior/posterior, lateral/medial e superior/inferior e dos esforços nos quatro principais ligamentos articulares, no decorrer de um amplo movimento de flexão/extensão. Estes valores foram comparados, de forma qualitativa, com valores equivalentes obtidos na literatura.

    Full Text Available Translation strategies in the face of cultural specificity of the 20th century Modern Greek prose translated into PolishAccording to Werner Koller, there are two main types of translations of texts which are connected to literature and culture. These types are adaptation and transfer. Adaptation is a result of using a translation strategy called domestication which consists in removing from the text all the elements which may seem odd or strange to the target reader and replacing them by some well-known units of the target culture. Transfer is a result of using a strategy called foreignization, that is of introducing to the target text some units characteristic of the source culture which may raise connotations of strangeness and foreignness. The choice of the strategy lies with the translator and depends on his vision of the target reader. The aim of this paper is to analyze translations of three Modern Greek novels into Polish with special attention paid to solutions chosen by the translators in the face of two main translation problems which are results of cultural specificity of the text: lexical problems and allusions to some historical, cultural and social facts as well as to the information these solutions provide on the translators’ vision of the target reader. Strategie tłumaczy wobec zjawiska obcości kulturowej w przekładach dwudziestowiecznej prozy nowogreckiej na język polskiWerner Koller wyróżnia dwa główne rodzaje przekładu tekstów związanych z literaturą i kulturą: adaptację oraz transfer. Adaptacja jest wynikiem użycia strategii tłumaczeniowej zwanej udomowieniem, która polega na usunięciu z tekstu elementów, które czytelnikowi docelowemu mogłyby wydać się obce i zastąpieniu ich dobrze znanymi mu elementami kultury docelowej. Transfer natomiast polega na zastosowaniu strategii zwanej egzotyzacją, tj. wprowadzeniu do tekstu docelowego elementów charakterystycznych dla kultury źródłowej, które mog

    Full text: The second RCM of this CRP was held in Morelia, Mexico from 21 to 25 April with Joseph Adu-Gyamfi as the Scientific Secretary. The RCM was attended by ten participants including six research contract holders, two technical contractors and two agreement holders. Four of the research contract holders could not attend because of visa-related issues and three of the agreement holders failed to attend. The participants were welcomed by Dr. Silvia Figueroa Zamidio, President, Universidad Michoacana de San Nicolas de Hidalgo, who acknowledged the valuable collaboration between her University and the IAEA through this CRP. The FAO Representative in Mexico, Dr. Norman Bellino, in his opening address, stressed that low available soil nutrients and severe nutrient depletion is a threat to food security and environmental sustainability. He was confident that this CRP, funded by the Joint FAO/IAEA programme, will go a long way to help developing innovative crop and nutrient management strategies that will enhance the adaptability of crops to low nutrient environments using nuclear and related techniques. Ms. Leonel Godoy Rangel, Constitutional Governor, State of Michoacan de Ocampo, opened the meeting. The Scientific Secretary (SC) outlined the objectives of the meeting which were to review, evaluate and discuss the achievements in accordance with the project objectives and agreed work plans, to discuss issues for implementing the second half of the CRP, and outline priorities, identify gaps and adjust work plans to achieve the overall objectives of the CRP. During an opening lecture on 'Integrated soil-plant approaches to increase crop productivity in harsh environment', the SC stressed the need to identify nutrient (nitrogen and phosphorus) sources and pools available to crop plants in low nutrient available soils. The SC presented a framework for the CRP outlining the three pillars, i.e. screening, evaluation (2006-2008) and adaptation mechanisms (2008

OBJETIVO: revisar a literatura, a fim de descrever as características respiratórias, posturais e vocais associadas aos estágios na DP e suas possíveis inter-relações. CONCLUSÃO: Na DP, a etiologia das manifestações respiratórias é multifatorial, sendo obstrutivas; restritivas; relacionadas à bradicinesia, à rigidez e às alterações posturais; fraqueza da musculatura; anormalidades na musculatura laríngea; interferência da medicação antiparkisoniana. A postura em flexão altera a dinâmica corporal, interferindo nas funções estomatognáticas e na relação tóraco-abdominal. As alterações vocais podem estar presentes desde os estágios iniciais com diminuição dos tempos máximos de fonação e da intensidade vocal; adução glótica incompleta; fendas glóticas; tremor e instabilidade fonatória; perturbações de frequência e de intensidade; e qualidade vocal alterada. Os déficits na força muscular respiratória se refletem no menor suporte respiratório à emissão vocal e, por consequência, na diminuição da intensidade vocal e dos tempos máximos de fonação. Do mesmo modo, a postura em flexão gera desvantagem biomecânica à atividade respiratória, com menor expansão e redução dos volumes pulmonares, e déficit na excursão diafragmática. Os distúrbios respiratórios, posturais e/ou vocais, à medida que a DP evolui, de acordo com os seus estágios, tendem ao maior comprometimento, apresentando efeitos na comunicação verbal e não-verbal.BACKGROUND: respiratory, postural and vocal manifestations, associated to stages in Parkinson's Disease and their possible interrelations.

    Full Text Available A síndrome de Brown é caracterizada por grande limitação de elevação em adução, elevação ligeiramente diminuída ou normal na abdução, anisotropia em "Y" ou "V", intorção do olho em supraversão e ducção forçada positiva. Sua causa se deve à inelastibilidade do músculo oblíquo superior ou por sua contenção em sua própria bainha. A hipermobilidade articular benigna é doença hereditária do tecido conectivo caracterizada por aumento da mobilidade em diversas articulações. Sua prevalência é muito variável em relação à idade, sexo e etnia, variando de 2 a 35% em homens e de 5 a 57% e mulheres. Neste relato os autores descrevem um caso de síndrome de Brown associada com hipermobilidade articular benigna e atentam para a associação pouco referida na literatura. J.C.S, masculino, 6 anos de idade, pardo, estudante, foi encaminhado à Universidade de Santo Amaro com queixa de exotropia há dois anos que aumentava na supraversão. Paciente com o diagnóstico de síndrome de Brown bilateral teve o diagnóstico de hipermobilidade articular benigna pelo Reumatologista. O paciente com hipermobilidade articular benigna pode desenvolver sintomas articulares como artralgia devido a uma inflamação articular. Acreditamos na possibilidade de que síndrome de Brown possa ter ocorrido devido a processo inflamatório na tróclea que teve início devido a hipermobilidade articular benigna.Brown's syndrome is characterized by a limitation of elevation in adduction, slight or normal limitation of elevation in abduction, divergence in straight upgaze (V-pattern, intorsion in upgaze and positive forced duction.

    Full Text Available O conhecimento dos problemas de saúde relacionados à voz ocupacional torna-se cada vez mais importante à medida que mais indivíduos usam a voz como instrumento de trabalho. Os músicos tocadores de instrumento de sopro são um grupo bastante específico de indivíduos que usa o trato vocal intensamente no exercício de suas atividades profissionais. Curiosamente, pouco ou nada temos relatado sobre a atuação direta da laringe nesta modalidade profissional. OBJETIVO: O objetivo do atual estudo foi avaliar o comportamento da laringe e do trato vocal de músicos tocadores de instrumento de sopro. MATERIAL E MÉTODO: Foram estudados 10 indivíduos tocadores profissionais de instrumento de sopro através de videonasofibrolaringoscopia, sendo observados o comportamento da laringe, faringe e língua durante o tocar do instrumento. RESULTADOS: Em todos os participantes deste estudo observamos que os tons musicais foram produzidos durante a adução das pregas vocais. O relato de maior dificuldade técnica de tocar determinada peça musical estava relacionado a uma maior tensão glótica (constricção látero-lateral e supraglótica. CONCLUSÕES: A glote participa ativamente da produção sonora do instrumento de sopro e que alterações na configuração glótica podem interferir na produção sonora musical final. Estes conhecimentos sugerem a necessidade de incluir os músicos tocadores de instrumento de sopro no grupo dos chamados profissionais da voz.INTRODUCTION: Knowledge of occupational voice disorders has gained increased importance as more individuals rely on their voices for their work.

    The system vibration is a very significant measure of the sawing performance, because it indicates the amount of energy required to saw the rock. The maintenance cost of system is also dependant on system vibration. A few increases in system vibration cause a huge increase in the maintenance cost of the system. In this paper, the vibration of system in terms of RMSa was investigated and models for estimation of vibration by means of rock brittleness indexes and operational specifications were designed via statistical models and multiple curvilinear regression analysis. In this study, the relationships between rock brittleness indexes and operational specifications were investigated by regression analysis in statistical package for social science (SPSS) and the results of determination coefficients have been presented. In the second part, the diagrams show that a point lying on the line indicates an exact estimation. In the plot for model, the points are scattered uniformly about the diagonal line, suggesting that the models are good. It is very useful to evaluate the vibration of system and select the suitable operational characteristics by only some mechanical properties of rock. Drgania układu uważane są za miernik wydajności procesu urabiania, ponieważ pokazują ilość energii niezbędnej do urabiania skały. Od poziomu drgań zależą także koszty eksploatacji systemu. Nieznaczny nawet wzrost poziomu drgań prowadzi do znacznego zwiększenia kosztów eksploatacyjnych urządzenia. W pracy tej przeprowadzono analizę drgań (ich wartości skutecznych) i opracowano model estymacji poziomu drgań w oparciu o współczynnik kruchości skał i parametry eksploatacyjne urządzenia. W pracy wykorzystano modele statystyczne i wielokrotną analizę metodą regresji krzywoliniowej.

    2014-12-01

    The catastrophic mine failure resulting from the inrush of water into the Wapno Salt Mine was probably caused by a fracture in the roof protection shelf. The purpose of the present study was to apply the method of the homogenization of the multi-level room-and-pillar structure in the Wapno Salt Mine for 3D+t modelling of the elastic-viscous medium to determine the distribution of stress and strain, and, on that basis, to estimate the geomechanical conditions existing in the roof shelf. This paper presents briefly the spatial development of the salt mine's structure and the results of the surveying measurements carried out during the salt mine's operation and after the mine was flooded. Those results constituted a basis for the verification of the introduced homogenization parameters, i.e. the time-dependent changes of the elasticity modulus and the susceptibility to creep at particular salt mine's levels. A simulated process demonstrated the development of positive values of principle stresses, increasing with time, and of omnidirectional tensile strains. In such conditions, the cracking of the protection shelf body could proceed, also with opening of water flow paths from the dome cap into the salt mine's workings. This paper presents a new research method, the results of its application, and the obtained distribution of stresses and strains that can be useful for the assessment of water hazard in other salt mines. Katastrofa górnicza wywołana wdarciem wody do kopalni soli w Wapnie spowodowana była prawdopodobnie pęknięciem ochronnej półki stropowej. Celem tej pracy było zastosowanie metody homogenizacji struktury komorowo-filarowej wielopoziomowej kopalni Wapno do modelowania ośrodka sprężysto-lepkiego 3D+t dla określenia rozkładu naprężeń i odkształceń oraz na tej podstawie oszacowania warunków geomechanicznych w półce stropowej.

    Full Text Available BACKGROUND: Proximal factors have been proposed to influence the biomechanics of the patellofemoral joint. A delayed or diminished gluteus medius (GM activation, before the foot contact on the ground during functional activities could lead to excessive femur adduction and internal rotation and be associated with anterior knee pain (AKP. There are few studies on this topic and the results were inconclusive, therefore, it is necessary to investigate the GM preactivation pattern during functional activities. OBJECTIVE: To compare the GM electromyographic (EMG preactivation pattern during walking, descending stairs and in single leg jump task in women with and without AKP. METHODS: Nine women clinically diagnosed with AKP and ten control subjects with no history of knee injury participated in this study. We evaluated GM EMG linear envelope before the foot contact on the ground during walking and GM onset time and EMG linear envelope during descending stairs as well as in a single leg vertical jump. Mann-Whitney U tests were used to determine the between-group differences in GM EMG preactivation pattern. RESULTS: No between-group differences were observed in GM linear envelope during walking (P=0.41, GM onset time and linear envelope during descending stairs (P=0.17 and P=0.15 and single leg jump (P=0.81 and P=0.33. CONCLUSIONS: Women with AKP did not demonstrated altered GM preactivation pattern during functional weight bearing activities. Our results did not support the hypothesis that poor GM preactivation pattern could be associated with AKP.CONTEXTUALIZAÇÃO: Tem sido proposto que fatores proximais influenciam a biomecânica da articulação fêmoro-patelar. Um atraso ou diminuição da ativação do glúteo médio (GM antes do contato do pé no solo, durante atividades funcionais, poderia levar a adução e rotação interna excessiva do fêmur e provocar a dor anterior do joelho (DAJ.

    , under the specific conditions of the georeactor operations within the time interval of 100 hours and 305 hours. The results of the numerical solution have been compared with the results of experimental results under in-situ conditions. Zaprezentowano wyniki badań modelowych polegających na numerycznej symulacji procesu podziemnego zgazowania węgla. Dla potrzeb realizowanej pracy dokonano wyboru oprogramowania wykorzystywanego do symulacji procesu podziemnego zgazowania węgla. Na podstawie przeglądu literatury zdecydowano, że oprogramowaniem, za pomocą, którego będą realizowane badania modelowe, będzie oprogramowanie informatyczne ANSYS-Fluent. Za jego pomocą przeprowadzano obliczenia numeryczne z zamiarem zidentyfikowania rozkładu zmian stężenia składników gazu procesowego w funkcji czasu trwania procesu zgazowania węgla. Przeprowadzone obliczenia miały charakter predykcji. W oparciu o dane konstrukcyjne georeaktora stosowanego podczas badań na KD Barbara oraz KWK Wieczorek, opracowano model geometryczny oraz wykonano jego dyskretyzację poprzez wygenerowanie odpowiedniej siatki numerycznej w oparciu, o którą wykonywane są obliczenia. Dane dotyczące sposobu zasilania georeaktora oraz parametrów utrzymywanych podczas procesu wykorzystano do definiowania modelu numerycznego. Część danych została uzupełniona w oparciu o źródła literaturowe. Głównym przyjętym założeniem było oparcie symulacji pracy georeaktora o modele opisujące reaktywny przepływ płynu. Składniki gazu procesowego oraz czynnik zgazowujący przemieszczają się wzdłuż kanału zgazowującego symulując zjawiska fizykochemiczne związane z transportem masy i energii oraz zachodzące reakcje chemiczne (wraz z efektem energetycznym). Chemizm procesu zgazowania oparto o równanie kinetyczne, które determinuje przebieg danego typu równania chemicznego zgazowania węgla. W ramach modelu opisano też interakcję gazu z otaczającą warstwą węgla. Opis ten dotyczy

Levando em conta os tipos de movimentos iniciais o autor observou que, quando nos pacientes com hemiplegia após AVC, os movimentos de flexo-extensão e oponência do polegar aparecem precocemente de forma isolada ou associada a movimentos da articulação proximal (ombro, ou central (cotovelo é de esperar melhor prognóstico do que nos pacientes cujo movimento inicial é representado por flexão do cotovelo e/ou flexão-adução do braço.The study aims the registration and analysis of the main facts which occur during recovery of the voluntary movements in the upper extremity, in patients with hemiplegia following cerebrovascular accident, and it also intends to evaluate the prognosis. Of particular interest was the comparative recognition of the spontaneous recovery of voluntary motricity in different segments of the upper extremity in 88 patients, not previously selected, with hemiplegia after cerebrovascular accident, admitted to the hospital at the acute stage. Of the 88 hemiplegic patients studied whose further evolution has been fairly followed 56 cases (group 1 experienced clinical improvement, either with partial or total remission of neurological manifestations and complete recovery of all voluntary movements in the different upper extremity joints, while 32 patients (group 2 with persistent neurological symptoms, particularly spasticity, showed a slighter clinical improvement, as well as only partial recovery of upper extremity movements. The clinical quantification of neurological signs applied in this study, has made possible to report the main significant changes developed during the 88 patients recovery. This criteria has allowed to enphasize the degree of the spontaneous remission of symptoms and the determination of the critical level of stabilization "plateau".

Jak wynika z przeprowadzonego przeglądu literatury, metoda ta nie jest powszechnie znana i używania przez przed- siębiorstwa, niemniej jednak posiada ona pewne zalety, uzasadniające jej wykorzystanie. Do jej głównych atutów należy zaliczyć łatwość zastosowania oraz "stabilność" uzyskiwanych wyników - wyliczony koszt kapitału własnego nigdy nie będzie przyjmował wartości mniejszych niż przyjęta stopa wolna od ryzyka. Omawiana metoda ma swoje szczególne zastosowanie do spółek (przedsiębiorstw), które nie są notowane na giełdach papierów wartościowych. Niniejszy artykuł składa się z pięciu części: wstępu, metody LEFAC, parametryzacji metody LEFAC (P-LEFAC), przykładu obliczeniowego oraz podsumowania. Druga cześć opracowania dotyczy charakterystyki metody LEFAC. W trzeciej części artykułu dokonano parametryzacji metody uzyskując funkcję określoną przez wzór 22.

Kategoryzacja zagrożenia wyrzutowego w krajach europejskich i w Chinach ma wiele cech wspólnych. Ustalane są najczęściej dwie, lub trzy kategorie zagrożenia. Często incydenty wyrzutów, bądź poważnych symptomów mogących świadczyć o zagrożeniu są podstawą do zaliczenia pokładu do najwyższej kategorii zagrożenia.

    This paper presents the results of studies on gas sorption performed by means of the gravimetric method. The tests were performed on two coal samples of different metamorphism degrees, came from two regions of Upper Silesian Coal Basin, Poland. The changes in sorption capacity of coals were measured in the pressure range from 0.1 MPa to 17 MPa and in temperatures ranging from 291K to 333K. Coal of a lower coalification degree was a better methane sorbent. Changes in sorption capacity of tested coals were linearly dependent on the temperature. The increase in temperature of 10K reduces the Langmuir sorption of about 0.7-0.8 [cm3/g]. Such increase of temperature causes a nonlinear increase of the Langmuir pressure (b-1). These results showed that the rise of rock temperature, caused by geothermal gradient, can induce a significant increase of equilibrium pressure of methane in coal seam. An increase of coal seam temperature may cause an increase of gas and coal outburst risk in a coal mine. W pracy przedstawiono wyniki badań sorpcyjnych wykonanych na dwóch rodzajach węgla o różnym stopniu uwęglenia. Próbki do badań pochodziły z kopalń „Sobieski" w Jaworznie oraz „Pniówek" w Pawłowicach. Badania polegały na przeprowadzeniu serii pomiarów izoterm sorpcji w różnych temperaturach układu węgiel-metan. Badania przeprowadzono metodą grawimetryczną, polegającą na pomiarze zmian masy węgla wywołanych sorpcją metanu. Maksymalne ciśnienie sorpcji wynosiło 1.7 MPa. Zakres zmian temperatury wynosił 40K. Dla węgla z kopalni „Pniówek" wykonano dodatkowo pomiary desorpcji metanu we wszystkich badanych temperaturach. Wyniki pozwoliły na wyznaczenie izoterm sorpcji przedstawionych w pracy oraz dopasowanie współczynników izoterm Langmuir'a. Węgiel o niższym stopniu uwęglenia okazał się lepszym sorbentem dla metanu. Zmiany wartości maksymalnych sorpcji Langmuira w funkcji temperatury mają charakter liniowy a współczynniki kierunkowe

Brykiety takie wykorzystywane są powszechnie jako paliwo w gospodarstwach domowych. Drobnoziarniste pyły węgla brunatnego (paliwa pyłowe) wykorzystywane są na skalę komercyjną do produkcji ciepła w paleniskach pyłowych. Pyły węglowe powstają nie tylko w trakcie suszenia węgla po procesie oddzielania w separatorach elektrostatycznych, lecz także w procesie mielenia suszonego węgla w młynach wibracyjnych. Żużel z kotłów w konwencjonalnej elektrowni, popioły z generatorów oraz te osadzające się w instalacji podlegają wysuszeniu, następnie wykorzystywane są jako wysokiej jakości materiał na podłoże w różnorodnych instalacjach. Popioły lotne wykorzystywane są przemyśle budowlanym jako częściowe zamienniki cementu. Po oddzieleni popiołu lotnego, gazy wylotowe kierowane są do instalacji odsiarczania z wykorzystaniem technologii wilgotnego wapienia, w wyniku tego procesu powstaje gips, wykorzystywany, miedzy innymi, w przemyśle budowlanym. Glinki z warstw nadkładu nad pokładami węgla wykorzystywane są powszechnie jako surowiec do produkcji sztucznego kruszywa "Liapor', wykazującego wyjątkowe właściwości termiczne i dźwiękoizolacyjne.

    Full Text Available Prevence představuje nejúčinnější prostředek proti užívání drog. Na jedné straně vytváří tělesná aktivita řadu faktorů, které vedou k přijetí zdravých stravovacích návyků, na druhé straně představuje prevenci užívání drog, protože sama o sobě určitým způsobem stimuluje tělo i mysl. Cílem provedeného výzkumu bylo stanovit stupeň obeznámenosti s návykovými látkami a jejich užíváním (například cigarety, alkohol a marihuana u dětí ve vztahu k frekvenci jejich zapojení do sportovních aktivit. Vzorek obsahoval 748 dětí, z čehož bylo 194 žáků a 189 žákyň čtvrtých tříd (jejichž průměrný věk byl 10 let ± 5 měsíců, a 201 žáků a 164 žákyň sedmých tříd (jejichž průměrný věk byl 13 let ± 4 měsíce. Uvedené údaje byly získány v rámci projektu "Tělesná/sportovní aktivita pro zdraví" probíhajícího v Ústavu kinesiologického výzkumu ve Vědeckém a výzkumném středisku Primorske univerzity ve slovinském Koperu. Použili jsme dotazník IPAQ (International Physical Activity Questionnaire, který jsme poněkud upravili pro věk a specifické vlastnosti respondentů. Pro stanovení vztahu mezi nečíselnými proměnnými jsme použili korespondenční analýzu. Pro číselné proměnné jsme použili analýzu variance a t-testy nezávislých vzorků. Všechny hypotézy byly ověřovány s 5% statistickou úrovní rizika (p = 0,05. Výsledky potvrdily u žáků statisticky významný vztah mezi sportovní aktivitou, kouřením a užíváním alkoholu a marihuany. Faktem je, že i když problém užívání drog nemůže být zcela odstraněn, mohli bychom ho zásadním způsobem redukovat. Jedním z nejdůležitějších faktorů pro snižování užívání drog je proto rovněž zapojení mládeže do vhodných sportovních aktivit (zvláště ve volném čase, což by mělo být řízeno a plánováno rodiči a učiteli. Prevention is the most

    Full Text Available A Disfonia Espasmódica Adutora é uma desordem neurológica do processamento motor central, caracterizada por contrações involuntárias e inapropriadas da musculatura fonatória, produzindo uma hiperadução das pregas vocais, o que promove uma voz trêmula, entrecortada e tensa-estrangulada. O objetivo deste estudo foi descrever os parâmetros vocais, acústicos e laríngeos pré e pós-tratamento fonoaudiológico realizado por meio da aplicação da Técnica de Emissão em Tempo Máximo de Fonação (TETMF em paciente com Disfonia Espasmódica de Adução. Esta técnica tem como objetivo promover o aumento da resistência glótica, melhorar a estabilidade fonatória e adequar a coaptação glótica. Participou deste estudo de caso uma paciente de 66 anos de idade, gênero feminino, com Disfonia Espasmódica Adutora. A paciente foi submetida à avaliação otorrinolaringológica e fonoaudiológica pré e pós-aplicação da TETMF. Foi verificada modificação de parâmetros vocais, acústicos e laríngeos, tais como a classificação da disfonia de G3R1B1A0S3I3 para G2R1B1A0S2I2, pitch de grave a adequado, traçado espectrográfico instável para mais estável e expressivo aumento da frequência fundamental média e da intensidade vocal média, além da melhora da eficiência glótica com o fechamento da fenda glótica anteroposterior. A terapia fonoaudiológica com a aplicação da TETMF foi considerada uma adequada opção de tratamento para o caso, tendo em vista os resultados alcançados, com destaque para a qualidade vocal e estabilidade fonatória. Ressalta-se a importância de novos estudos para comprovação da eficácia da técnica no tratamento da Disfonia Espasmódica Adutora.Adductor Spasmodic Dysphonia (ASD is a neurological disorder of central motor processing, characterized by involuntary and inappropriate contractions of the phonatory muscles, producing hyperadduction of the vocal folds, which causes a tremulous, faltering

The various scenarios for restoring their memory are also present in this part: cleansing in the past, establishment in the present and liberation in the future. Their image is made complete by a short presentation of heritage canonisation patterns and ethnocentric re-evaluation of methodologies in the Macedonian humanities after 1991.  „Nowa epoka” jako kategoria kompensacyjna. Metodologiczne wyzwania opisu a casus dwudziestowiecznej MacedoniiW artykule przedstawia się funkcje i możliwe sposoby opisu macedońskich wizji histo­riozoficznych i kulturowych wyrosłych na gruncie politycznego przełomu 1991 roku – ujęte na tle przemian kolektywnej świadomości w XX wieku. Problemy metodologii badań oraz tożsamości idei nowego początku (i jej części składowych ukazane są w czterech kontek­stach: genetycznym, ontologicznym, aksjologicznym i procesualnym. W ramach pierwszego z nich zwraca się uwagę na takie zagadnienia jak retrospektywna orientacja temporalna, asymilacja przeszłości, „synchronia historii” i odbicia prototypów, nowa konceptualna sieć rekonstruowanych znaczeń, selekcja związków przyczynowych. Drugi kontekst odnosi się do celowościowo-zbawczego wyobrażenia czasu, dominacji „historii strukturalnej”, twórczego zastosowania dawnych – głównie romantycznych – kategorii historiozoficznych: moralnej predestynacji narodu (Hegel, kryzysu jako czynnika zmiany (Burckhardt, podrzędności kategorii historii wobec wolności w następstwie epok (Fichte, przełomu powstrzymującego proces rozkładu (corso – ricorso – Vico, znaczenia periodyzacji i cezur. W trzecim kontekście zawierają się między innymi następujące problemy: więź pochodzenia a roszczenie nowości i wyzwolenia, „korekta niespełnienia” przeszłości, „pozytywna apokalipsa” permanentnej rewolucji narodowej

    -causing mutations in both alleles of the NBN gene are known. No specific therapy is available for NBS, however, hematopoietic stem cell transplantation may be one option for some patients. Prognosis is generally poor due to the extremely high rate of malignancies. Zespół Nijmegen (Nijmegen breakage syndrome; NBS jest rzadkim schorzeniem z wrodzoną niestabilnością chromosomową dziedziczącym się w sposób autosomalny recesywny, charakteryzującym się przede wszystkim wrodzonym małogłowiem, złożonymi niedoborami odporności i predyspozycją do rozwoju nowotworów. Choroba występuje najczęściej w populacjach słowiańskich, w których uwarunkowana jest mutacją założycielską w genie NBN (c.657_661del5. Do najważniejszych objawów zespołu zalicza się: małogłowie obecne od urodzenia i postępujące z wiekiem, charakterystyczne cechy dysmorfii twarzy, opóźnienie wzrastania, niepełnosprawność intelektualną w stopniu lekkim do umiarkowanego oraz hipogonadyzm hipogonadotropowy u dziewcząt. Na obraz choroby składają się także: niedobór odporności komórkowej i humoralnej, który jest przyczyną nawracających infekcji, znaczna predyspozycja do rozwoju nowotworów złośliwych (zwłaszcza układu chłonnego, a także zwiększona wrażliwość na promieniowanie jonizujące. Wyniki badań laboratoryjnych wykazują: (1 spontaniczną łamliwość chromosomów w limfocytach T krwi obwodowej, z preferencją do rearanżacji chromosomów 7 i 14, (2 nadwrażliwość na promieniowanie jonizujące lub radiomimetyki, co można wykazać metodami in vitro, (3 radiooporność syntezy DNA, (4 hipomorficzne mutacje na obu allelach genu NBN, oraz (5 brak w komórkach pełnej cząsteczki białka, nibryny.

Prličev dobrze zna starogrecki i jest znawcą twórczości Homera. Pod wpływem poezji Homera pisze w archaizowanym języku greckim poemat epicki zatytułowany ‛Ο 'Aρματωλός (w macedońskim przekładzie Сердарот albo Мартолозот, który przynosi mu zwycięstwo w konkursie poetyckim w Atenach w 1860 roku. Jego drugie dzieło epickie zatytułowane Σκενδέρμπεης jest napisane także w duchu poezji Homera, głównie jeśli chodzi o styl (epitety i porównania i kompozycję (opracowanie typowych dla eposu motywów tematycznych. Obydwaj są także tłumaczami, Džinot zapowiada w prasie przekład Antygony Sofoklesa, o losach przekładu nic nam nie wiadomo, a Prličev dokonuje poetyckiego przekładu Iliady Homera na wymyślony przez siebie język, który jest w istocie mieszanką języków słowiańskich, a sam autor nazywa go "ogólnosłowiańskim". Влијанието на старогрчката култура врз македонската литература во XIX–иот векВо рамките на Турската Империја од која Македонија е дел во текот на 19-иот, македонскиот народ е изложен на политичка пресија и културното влијание и на Турција и на некои соседни држави. Под влијание на пропагандата на владата во Атина која отвора свои школи во Македонија, а во исто време и зафатени од бранот на романтизам, некои македонски интелектуалци се запознаваат со старогрчката култура што ќе остави силен печат врз нивното литературно

    agent in the capital landscape is the state. It is the bureaucracy of the state, appearing in the role of executor of the national will, deciding on the shape of the image of the city, reinforcing those values that seem to be desirable from the perspective of the represented group. The lack of that factor leads, as in the case of Skopje, to the preservation of the local past and/or to a haphazardly implemented publicly sponsored construction. In both cases discussed above, the map and the landmarks mirror the most important categories of national narrative. The shape of this narrative depends largely upon the central authorities of the nation.Ciągłość i nieciągłość w przestrzeni miasta stołecznego: Paryż i SkopjePrzedmiotem niniejszego artykułu jest zagadnienie tworzenia wizji ciągłości dziejowej, a więc usensowionej narracji o przeszłości, w przestrzeni miasta. Miasto bowiem jawi się jako przestrzeń kulturowa par excellence i ono właśnie stwarza najlepsze możliwości wpływu na interpretację poprzez tworzenie specyficznego układu odniesień symbolicznych i obrazów, pobudzających grę interpretacji. Miasto zamieszkiwane jest przez wiele jednostek i różnorakich grup, co zmusza je do negocjacji znaczeń. Przedmiotem przedstawionych tu badań są stolice. Stolica państwa to bowiem miasto szczególne, co zazwyczaj podkreśla sam status prawny ośrodka stołecznego regulowany przez specjalną ustawę, staje się niezwykle ważną przestrzenią symboliczną, miejscem pokazu państwowej i narodowej siły, eksponowania i utwierdzania tożsamości, prezentowania wizerunku obcym oraz kształtowania pożądanego wizerunku na użytek obywateli – członków swojej grupy. Na przykładzie Paryża i Skopja, miast o odmiennej kontekstowo historii, chciałbym pokazać specyficzne dla przestrzeni miejskiej sposoby indukowania interpretacji, albowiem mimo oczywistych różnic oba miasta pozwalają dostrzec historyczny okres, w którym samo miasto stało si

    , dla badanych pyłów wyznaczono izotermy adsorpcji pary wodnej (Rys. 1). Uzyskane niższe wartości adsorpcji dla materiałów po modyfikacji niż dla proszku surowego potwierdzają, że materiały posiadają charakter hydrofobowy, co pozwala stwierdzić, że obie proponowane metody hydrofobizacji są użyteczne do produkcji wodoodpornego pyłu wapiennego. Analizę termiczną pyłów wapiennych wykonano w celu porównania efektu cieplnego przemian zachodzących podczas ogrzewania pyłów modyfikowanych z efektem cieplnym zachodzącym podczas ogrzewania surowego pyłu wapiennego. W trakcie badań użyto termowagę firmy TA Instruments 2960 SDT ze sprzężonym spektrometrem masowym firmy Balzers TermoStar 300. Otrzymane wynikiprzedstawiono na Rys. 2. Linie ciągłe na Rys. 2a i 2b przedstawiają przebieg krzywych TG, DTG oraz DTA dla pyłu surowego. Linie przerywane zostały otrzymane dla pyłu modyfikowanego kwasem stearynowym (Rys. 2a) oraz preparatem SARSIL® H-15 (Rys. 2b). Na Rys. 3 zobrazowano wyniki analizy zawartości tlenku węgla IV w składzie gazów otrzymywanych podczas rozkładu termicznego pyłu wapiennego (EGA). Krzywa otrzymana dla pyłu modyfikowanego kwasem stearynowym w zasadzie pokrywa się z krzywą otrzymaną dla pyłu surowego. Parametry uzyskane z użyciem aparatu Powder Characteristics Tester umożliwiły scharakteryzowanie pyłów wapiennych nie tylko pod kątem ich właściwości hydrofobowych, ale także właściwości kohezyjnych i przepływowych.
