Authors: Büyükcangaz Hakan
Published: September 2018

The aim of this study was to determine the effect of deficit irrigation on yield for cabbage grown under unheated greenhouse condition. The research was carried out at the Agricultural Research Station of Yenişehir High School of Uludağ University in Bursa, Turkey, in 2008. In the study, water was applied to cabbage as 1.00, 0.75, 0.50, 0.25 and 0.00% (as control) of evaporation from a Class A Pan corresponding to 2 day irrigation frequency. Irrigation water applied ranged from 70 to 520 mm and water consumption ranged from 90 to 548 mm. The effect of irrigation water level on the yield, head height, head diameter, head weight and dry matter were found to be significant. The highest yield was 72.8 t ha-1. Crop yield response factor for cabbage (ky) was found as 1.036. The highest values of water use efficiency (WUE) and irrigation water use efficiency (IWUE) for 2008 year of K2cp treatment was calculated to be 0.143 kg m-3 and 0.137 kg m-3, respectively. K2cp application (75%) can be recommended as the most effective irrigation level for the cabbage to which drip irrigation is applied under scarce and unheated greenhouse conditions.

Published: September 2018

This study was conducted with the objectives to determine the effects of licorice root powder (Glycyrrhriza glabra) on performance, serum parameters, egg yolk cholesterol and antioxidant capacity in laying Japanese quail. Two hundred and forty 10-wk-old Japanese quails were randomly assigned to four dietary groups, each one four times replicated with fifteen quails per dietary groups. Control group fed the basal diet; other groups were fed basal diet supplemented with 0, 0.5, 1.0 and 1.5% licorice root powder. There were no significant differences in terms of final live weight, feed intake, feed conversion ratio, egg weight, serum cholesterol, triglyceride and High-Density Lipoprotein (HDL) concentration between treatment groups. Egg production was higher in control group and 0.5% licorice root powder supplemented groups. 1.0% licorice root powder supplemented group had lower egg production rate. Licorice root powder supplementation decreased Low Density Lipoprotein (LDL) concentration and increased glucose concentration significantly. Licorice root powder supplementation increased total antioxidant status (TAS) and reduced total oxidant status (TOS) and oxidative stress index (OSI). It was concluded from this study that supplementation of licorice root powder at the level of 0.5, 1.0 and 1.5% to the feed of laying quails had no adverse effects on performance. Licorice root powder supplementation can be used to reduce cholesterol level and increase antioxidant status in quails.

Authors: Korchagin P. A , Letopolskiy A. B. , Teterina I. A.
Published: September 2018

Introduction. Nowadays there is sufficient number of the working bodies’ parameters, which allow performing technological operations in different conditions with minimal labor and energy resources. It is necessary to produce significant excavation during roads’ construction. Therefore, to perform such technological procedure excavation and road machinery are used. The motor grader is an earth-moving machine and is necessary for surface profiling, moving and construction materials’ level.

The motor grader efficiency is determined by the performance criterion. World producers of earthmoving and road machinery associate the growth of quality and speed of work with the improvement of the executive working bodies. Moreover, new design variants of dumps are being developed, including design variants for motor graders. Such solution would allow to reduce the necessary number of passages along the construction site and to shorten the time for mounting the working body. The article presents the variant of the motor grader working equipment improving by installing the side working dump.

Materials and methods. The calculated dependences of the main parameters of the motor grader are obtained, such as the coupling weight, the nominal traction force, the resistances arising in the operating mode when cutting and moving the ground, and the total engine power for the operating mode at 4 km per hour speed. Strength characteristics of the side working equipment of the motor grader are investigated. The analysis is carried out by using the Solid Software.

Results. The results of the theoretical studies are presented graphically and reflected the stresses, displacements and deformations in proposed lateral working equipment of the motor grader. Using the Solid Works software product it is possible to determine the safety margin of the proposed design. The conducted research allows confirming the working capacity of the proposed technical solution.

Discussion and conclusion. The proposed technical solution allows increasing the productivity of the machine while performing the planning works, while maintaining the specified accuracy of their implementation. In addition, such design allows profiling not only the horizontal surface, but also the embankment construction when the side blade is located at an angle of up to 20 degrees.

Published: September 2018

Introduction. Increased technical requirements for roads, associated with increasing axial loads, the intensity and speed of vehicles, with the actual technical condition of the roads number, engineering structures, including culverts, activation of federal and regional services to bring the parameters of road surfaces to the world standards, all listed parameters pose the task in developing the mathematical modeling methods of physical-mechanical characteristics of soils in the culverts area. Therefore, such methods allow to reduce economic costs and time for carrying out experimental research of deformations based on the monitoring results of the soil roadbed and pavement.

Materials and methods. The order of technical condition of the culverts’ research, pavement and physico-mechanical characteristics of soils, methods of experimental research were discussed in the article. Moreover, the approach to carrying out experimental works on penetration of pits in places of deformations and nearby was approved. Additionally, the evaluation of the soils condition on the roadbed and the annular space of the culverts was made.

Results. The schemes of deformation and elasticity, density, humidity, consistency, plasticity number, fluidity, and physical properties of the soil are determined. The engineering-geological elements, mean values of density, humidity and compaction factor are established according to the research aim. Consequently, the values of the strain modules and the modulus of elasticity are calculated on the basis of compression and stamp tests.

Discussion and conclusions. The dependence of the pavement on the physic-mechanical characteristics of the soil of the roadbed is proved. The correlation-regression analysis of soil characteristics is performed on the basis of experimental research. As a result, the regression equations are obtained in the annular space of culverts and at the distance of ± 30 m nearby. As could be proved, there are irregularities in the coverage of road clothes caused by drawdown in barrier locations. The physic-mechanical characteristics of the ground and strength characteristics are increased by culverts’ transfer on distance. The application of physic-mechanical characteristics of the soil together with experimental studies makes it possible to reduce labor costs, time and cost of testing.
EXPERIMENTAL INVESTIGATION OF DEFLECTED MODE OF THE RIENFORCED CONCRETE BEAMS WITH ORGANIZED CRACKS UNDER LONG-TERM LOADING
Authors: Ckhum A.
Published: September 2018

Introduction. Evaluation of the influence level of the pre-organized cracks in tensile zone of the reinforced concrete beams on their crack resistance, deformability under long-term loading is investigated in the article.

Materials and methods. Concrete for specimen was produced in laboratory and factory on portland cement of the 500-grade at W/C=0,71; concrete composition 1:1,9:4 (by weight); strength of cube at 28th days – 13,85 MPa; strength of prism with dimensions 10/10*40 cm – 11,48 MPa; span calculation – 78 cm; steel rebar grade – A400 with diameter of 10 mm. Organized crack was formed by installing plate with thickness of 0,5 mm and height of 30 mm on the rebar in the zone of maximum moments.

Results. The experiments confirmed the hypothesis about the beams rigidity with pre-organized cracks in comparison with stochastic cracks under the influence of long-term loading. As a result, the beams with pre-organized cracks provide the smaller deflection after long-term period than the beams without organized cracks. Thus, the proposed method of the deflections calculation of the reinforced concrete beams with pre-organized cracks under the long-term loading helps to reduce deflection to 33%.

Discussion and conclusion. The findings of this study suggest that the presence of pre-organized cracks reduces the beams deflections in comparison with the specimens of section, and such method actually regulates the stress-strain state of reinforced concrete structures and leads to the smooth deformation at all stages under the influence of long-term loading.

Authors: Uskova I. V.
Published: September 2018

The author discusses a currently important issue –design of the textbook-based home assignment in teaching the Russian language as a school subject. The author views the purpose of this article in drawing attention to that issue, because home assignments largely consist of textbook exercises. However, since the goals of education, principal approaches to the design of the educatory process, and the teaching environment have changed in the past decade, it is necessary to update approaches to the design of schoolchildren’s home assignments in the Russian language. Having based on advanced methods of academic research, completed experimental work and her own school-teaching experience, the author comes at the conclusion that existing textbooks of the Russian language provide ample opportunities for the design of home assignments targeting development of modern education’s key skill in the students – ability to self-educate. At the outcome, the study helps to identify the teachers’ priorities in organizing homework of schoolchildren and describes the vectors of changes in organizing textbook-based homework. The working methods and techniques proposed by the author take into consideration the informational and educatory environment of the contemporary school student, and have been tried out and evaluated within the framework of experimental activities.

Published: September 2018

With the increase of population and change in lifestyle, the quantity and quality of solid waste has drastically changed in Indian society. Aspects involved in solid waste management are mostly, collection, transportation, disposal and processing. The disposal of solid waste is concerned with disposal process followed and availability of disposal land. Proper care should be taken in choosing the disposal area and disposal mechanism. Monitoring of the sites is priority criteria for successful management of solid waste as leachate generation occurs which is associated with ground water as well as surface water contamination near dumping sites. Surface water system situated near the disposal or landfill sites shows more toxicity as the dose of toxicants passage from the nearby landfill [1]. This note is simplified on the basis of guidelines on landfill gas management by SEPA, 2004 [2]. Through this short note, authors make a glimpse of landfill gas characteristics and management practices.

Published: September 2018

In the present work, green synthesis of silver nanoparticles (AgNPs) using a natural phytochemical agent has been described. The aqueous latex from Musa paradisiaca peduncle has been utilized as reducing as well as stabilizing agent. The formation of AgNPs was optimized by varying latex and AgNO3 concentrations and finally reaction time. Ultraviolet-visible spectroscopic analysis showed the surface plasmon resonance peak between 350 and 450 nm confirms the formation of silver nanoparticles. X-ray powder diffraction analysis revealed the crystalline nature of AgNPs, Fourier transform infrared spectroscopy analysis revealed that AgNPs were stabilized by polyphenols and other aromatics present in the Musa Paradisiaca peduncle latex, while X-ray energy dispersive spectroscopy confirms the metallic nature. The field emission scanning electron microscopy and high resolution transmission electron microscopy showed the spherical shape of the particles and size distribution of AgNPs measured by dynamic light scattering which are in the range of 40 to 50 nm. The synthesized AgNPs showed photocatalytic activity on the degradation / removal of the methylene blue dye and the antimicrobial activity against Pseudomonas aeruginosa, Staphylococcus aureus and Klebseilla bacterial species.
California DREAM: The Impact of Financial Aid for Undocumented Community College Students
Authors: Ngo Federick , Astudillo Samantha
Published: September 2018

Ineligibility for state financial aid has traditionally limited undocumented students’ access to higher education. Since 2013, the California Development, Relief, and Education for Alien Minors Act (CA-DREAM) has made state-supported aid available to undocumented college students with demonstrated financial need. We use a difference-in-difference strategy and administrative data to examine the impact of the policy on undocumented community college students’ enrollment behaviors and postsecondary outcomes. The availability of CA-DREAM aid for these students, in the form of enrollment fee waivers, drew in undocumented Hispanic male students, students with lower average incoming high school GPAs, and those who increased their 11th to 12th grade achievement. Receiving DREAM aid significantly increased the average number of units attempted and completed and, in some cases, improved persistence and attainment outcomes. Undocumented students receiving aid achieved at similar levels as U.S. citizen peers receiving aid and better than their undocumented peers not receiving aid.

This study aims to find out about bureaucracy transformation in the management of regional assets covering administrative reform, transparency, and professionalism of apparatus in the management of regional assets. The method of this research is qualitative with descriptive type. Data collection was done by observation and interview. The results showed that the asset management is centralized to be easily monitored. Moreover, asset has many types, ranging from moving goods to the immovable, while Perfection of performance is done by monitoring function by leader to activity or program of asset management of area which is being implemented. The government's responsibility to provide accurate information about local assets still takes time for inventory through the asset census because of the many local assets it has. Transparency of asset management is important to do because without the existence of transparency of management hence difficult to succeed in improving performance management of local property become WTP (Wajar Tanpa Pengecualian). Then to improve the professionalism of the apparatus of the asset area then there will be held a training for goods committee so that rules related to the utilization of regional property can be understood.

Systematic conservation planning (SCP) has increasingly been used to prioritize conservation actions, including the design of new protected areas to achieve conservation objectives. Over the last 10 years, the number of marine SCP studies has increased exponentially, yet there is no structured or reliable way to find information on methods, trends, and progress. The rapid growth in methods and marine applications warrants an updated analysis of the literature, as well as reflection on the need for continuous and systematic documentation of SCP exercises in general. To address these gaps, we developed a database to document SCP exercises and populated it with 155 marine SCP exercises found in the primary literature. Based on our review, we provide an update on global advances and trends in marine SCP literature. We found accelerating growth in the number of studies over the past decade, with increasing consideration of socioeconomic variables, land-sea planning, and ecological connectivity. While several studies aimed to inform conservation decisions, we found little evidence of input from practitioners. There are important gaps in geographic coverage and little correspondence with areas most threatened. Five countries lead most studies, but their networks suggest potential for capacity building through collaborations. The varying quality and detail in documentation of studies confirmed the limited opportunities to develop and assess the application of best practice in conservation planning. A global database to track the development, implementation, and impact of SCP applications can thus provide numerous benefits. Our database constitutes an important step towards the development of a centralized repository of information on planning exercises and can serve several roles to advance SCP theory and practice: it facilitates assessing geographic coverage and gaps; scientists and practitioners can access information to identify trends in the use of data, methods, and tools; reviewers and editors of journals can assess whether studies have covered important literature and developments; donors and non-government organizations can identify regions needing further work; and practitioners and policy-makers can learn from previous plans.
Can Abraham bring peace? The relationship between acknowledging shared religious roots and intergroup conflict
Authors: Kunst Jonas R.
Published: September 2018

Although the protracted Israeli-Palestinian conflict is rooted in contesting ethno-national narratives, it is often also framed and perceived in religious terms. While all three groups who consider the region a holy land, namely Jews, Muslims and Christians, have theological roots in common, the potential of emphasizing such commonalities among more than two groups and - most importantly - whether acknowledging such shared Abrahamic lineage generally may be an asset for actual peacemaking in the region remains unknown. Focusing on the Israeli-Palestinian conflict, we aimed to fill this gap using diverse groups and contexts. In Study 1, American Jews acknowledging their shared Abrahamic lineage with Muslims were more supportive of aid to, and peacemaking with, Palestinians. Next, we broadened this categorization to also include Christians. In Study 2, the more American Jews acknowledged this extended categorization including all three groups, the less biased they were toward Muslims and Christians and the more they supported political and territorial conflict solutions. We then took the paradigm to the Middle East. In Study 3, Israeli Jews acknowledging the Abrahamic category showed less bias toward Muslims and Christians and were more supportive of peacemaking, intergroup contact and the two-state solution. Finally, in Study 4, Palestinian-Muslims living in the Palestinian Territories who acknowledged this shared religious lineage showed less bias toward Jews, yet more bias toward Christians. In all studies, findings held when controlling for political orientation or social dominance orientation. Implications for using religious and Abrahamic categorizations for conflict resolution and intergroup relations are discussed.
Does MRI acoustic noise affect chemosensory perception?
Authors: Havermans Remco , Hendriks Anouk Elisabeth Matheus
Published: September 2018

Introduction. Sounds can affect food and flavour perception. For example, loud noise can affect taste perception. In the present study, we examined whether exposure to ~80 dB magnetic resonance imaging (MRI) acoustic noise affects taste perception. Methods. Participants (N = 27) came to the lab twice for a taste test, a smell test, and evaluating sweet and savoury food items: once when continuously being exposed to loud MRI acoustic noise and once when being exposed to much quieter background noise. It was hypothesized that exposure to loud noise would impair taste perception,especially identifying and detecting sweet taste, and that it would decrease liking for the taste of particularly sweet foods. Results. Neither overall taste detection nor sweet taste detection was affected by exposure to (f)MRI acoustic noise. Further, we found no effect of noise on sweet food liking, but exploratory analyses do imply such an effect of MRI noise on liking for savoury foods, with these foods being significantlyless liked when exposed to MRI acoustic noise. Conclusion. We conclude that loud noises do not necessarily affect chemosensory perception. Implications. MRI acoustic noise specifically does not seem to have a relevant effect on smell and taste.
Fake Math-Dislike Students in Japan and East Asian countries
Authors: Mori Kazuo , Uchida Akitoshi
Published: September 2018

International surveys repeatedly showed that Japanese children were good at mathematics but disliking it. We hypothesized there were a considerable number of “fake math-dislikes” among Japanese students who claimed they disliked mathematics explicitly while accepted it implicitly. To examine this hypothesis, we administered questionnaires and paper-based implicit association tests (IAT) to 204 Japanese junior high school students (13-14 years old) and found 38 fake math-dislikes (Study 1). We hypothesized further that those fake math-dislikes would become real math-dislikes eventually and that informing of their implicit attitude toward mathematics might work preventing this undesirable transition. Then, in Study 2, we randomly assigned them into experimental and control groups and informed only the experimental students of their positive implicit attitude toward mathematics we revealed with the IAT. One year later, we found 15 of the 16 experimental students improved their math achievement scores while only nine of the 17 control students did. The simple practice of informing of their implicit attitude worked effectively for improving their math achievement. As hypothesized, it prevented the fake math-dislike students from turning into real math-dislikes.
Living on the Edge. Neighborhood Boundaries and the Spatial Dynamics of Violent Crime
Authors: Legewie Joscha
Published: September 2018

Neighborhood boundaries are a defining aspect of highly segregated urban areas. Yet, few studies examine the particular challenges and spatial processes that occur at the bordering region between two neighborhoods. Extending the growing literature on spatial interdependence, this article argues that neighborhood boundaries—defined as sharp changes in the racial or socioeconomic composition of neighborhoods—are a salient feature of the spatial structure with implications for violent crime and other outcomes. Boundaries lack the social control and cohesion of adjacent homogeneous areas, are contested between groups provoking intergroup conflict, and create opportunities for criminal behavior. This article presents evidence linking racial neighborhood boundaries to increased violent crime. The findings illustrate the importance of neighborhood boundaries for our understanding of spatial dimensions of population dynamics above and beyond the characteristics of neighborhoods.
The “mutual ignoring” mechanism of cyberbalkanization: triangulating observational data analysis and agent-based modelling
Authors: Chan Chung-hong , Fu King-wa
Published: September 2018

Cyberbalkanization has been observed in some online activities, but its mechanism remains uncertain. Drawing on the Social Balance Theory, we theorized that the formation of “mutual ignoring” triads (three actors in a group with only a pair of interacts) in a network is a key procedure for cyberbalkanization. A cyberbalkanized network was constructed using data shared on Facebook Pages during the 2014 Hong Kong protests. Our findings indicate “mutual ignoring” was a prominent triad network configuration, whereas no such configuration was found in randomly generated networks. Our empirical-based observation was retested with simulation by agent-based model, confirming that “mutual ignoring” is essential for the emergence of cyberbalkanization. A strategy is then suggested to minimize cyberbalkanization.
Rabbi Nachman of Breslev and Cognitive Therapy: A Short Comparison of Conceptual and Educational Similarities
Authors: Katz Yaacov J
Published: September 2018

Rabbi Nachman of Breslev, born in 1772, was the great-grandson of Rabbi Yisrael Baal Shem Tov (Master of the Good Name) and founder of the Chassidic movement. He grew up to be an outstanding and charismatic Chassidic master. During his lifetime he attracted a group of devoted followers who looked to him as their prime source of spiritual guidance in their quest for God. The teachings of Rabbi Nachman focused on a number of key concepts such as faith in God, simplicity, study of Jewish sources (bible, talmud, legal code) individual and private prayer, and joy. He taught his followers that deviant past actions result from perceiving illusions which contorted reality. In addition, these illusions which led in the past to transgressions and deviant religious and social behavior, need to be rationally understood in order to erase them. The individual needs to focus on the rational present in order to improve his or her perceptions and actions and to live according to God's will. Unlike classical depth psychology which dwells on problematic key personality issues linked to the individual's past and are usually embedded in the subconscious or the unconscious, cognitive therapy suggests that problematic issues affecting the individual can be dealt with by helping the individual to rationally overcome difficulties by identifying and changing dysfunctional thinking, beliefs, behavior, and emotional responses. Cognitive therapy consists of testing the assumptions which one makes and identifying how some of one's usually unquestioned thoughts are distorted, unrealistic and unhelpful on the one hand and what the individual needs to do in order to view life rationally on the other.The conceptual definitions used by Rabbi Nachman in his theological model expounded in the latter part of the eighteenth century and by those espousing the model underlying cognitive therapy in the 20th and 21st centuries are remarkably similar and seem to have evolved from the same psychological assumptions. The similarities between the principles underlying two theories are analyzed and discussed in the present paper.
Tectonic Study of Lineaments for Part of Zagros Belt, Northeast Iraq
Authors: J. Alabidi Abdulkadhim
Published: September 2018

The study area situated in the western part of Zagros fold-thrust belt, north east (NE) Iraq. Google earth image for study area was used to build up lineaments map. Studying and processing of these lineaments revealed that there are two dominant directions of lineaments northeast-southwest (NE-SW) and northwest- southeast (NW-SE), compatible with the main regional stress direction and Zagros belt direction respectively. It was found that there is no significant change of lineaments density in different tectonic zones and there is no obvious effect of lithology on lineament density in the study area. Length rose diagrams showed an obvious increase in the value of NW-SE lineaments direction, starting from low folded zone toward NE, despite frequency rose diagrams of different tectonic zones showed no significant change of the main prevailing direction. It is found that some lineaments shifted or bended some folds or ridges in the study area.   Field observations demonstrated that some lineaments of study area had field criteria of faults while they did not described in tectonic map.

This research illustrates the results of a study on the synthesis of maleic anhydride-vinyl acetate copolymers (MAVA) with the monomer molar ratio of 1:1 by the radical polymerisation method in which benzoyl per-oxide was used as a catalyst. The structure and compo-sition of MAVA were characterised by FTIR, 1H-NMR and 13C-NMR spectra. The molecular weight of the co-polymers was determined by the viscosity method. The copolymers were then modified by the esterification reaction with hexadecanol - a long alkyl chain alcohol. The modified copolymer products (MAVAC) were used as additives to improve the cold flow properties of palm oil-based biodiesel through pour point temperature measurement according to standard ASTM-D97 and dynamic viscosity according to ASTM D445-97. The re-sults showed that the MAVAC additives with the comb-shape structure at the concentration of 1000 ppm could decrease the pour point temperature of palm oil-based biodiesel by 5.5oC and dynamic viscosity by 0.17 cPs.

Authors: Panka I. , Hegyi Gy. , Keresztúri A. , Maráczy Cs. , Temesvári E.
Published: September 2018

In VVER-1000/1200 type reactors much higher and geometrically more complex assemblies are applied compared to the VVER-440 design. Additionally, assembly shrouds are not used in the improved reactor types. This implies that the existing sub-channel wise models and hot channel calculation methodologies used in the safety assessment of VVER-440 reactors have to be improved. For this purpose a full core thermal hydraulic model was developed. In the first part of the paper the new model and its connections with the reactor physics of KARATE-1200 code system are demonstrated with results regarding the sub-channel outlet temperature and DNBR. In the second part of the paper the hot channel calculation methodologies to be used in the transient safety analyses of VVER-1200 type reactors are discussed. The appropriate frame parameter concept concerning the limitation of the heating up of the coolant and the single closed sub-channel approach vs. the multi-channel approach are studied, as well.
SIMULATE5-HEX extension for VVER analyses
Authors: Bahadir T.
Published: September 2018

Studsvik's 3D, steady-state, nodal code SIMULATE5, which is widely used for square lattice geometries, has been recently extended to hexagonal geometry for the analysis of VVER 1000 and VVER 1200s. The lattice physics code CASMO5 is used for generating nodal cross sections data from single assembly calculations. SIMULATE5's HEX extension solves the multi-group diffusion equation, or optionally SP3 equations, for the hexagonal-z geometry by dividing each hexagonal into six triangles. In each triangle, the Fourier solution of the wave equation is approximated by eight plane waves to describe the intra-nodal flux accurately. The cross sections are described by a hybrid microscopic-macroscopic model that includes approximately 60 heavy nuclides and fission products. Heterogeneities, due to spacer/grid and control rod, in the axial direction of an assembly are treated systematically. This paper summarizes the physics models employed in SIMULATE5-HEX as well as the initial benchmarking activities.
Power transient calculations with VERONA
Authors: Horváth M. , Pós I. , Parkó T.
Published: September 2018

In Paks Nuclear Power Plant the VERONA core monitoring system is being used. In this article there is a new way presented to determine the precision of VERONA calculations during power transients. In that case VERONA uses a sophisticated method to follow the changes of the core. During a transient many online measured parameters cannot be used to determine the precision of the model due to their insufficient accuracy. However the change of the calculated boric acid concentration can be used for this purpose. If there is no inlet of boric acid or clean condense during the transient, at the end, the calculated boric acid concentration value should be equal to that, which was determined at the beginning of the power transient. However there is often a difference between these two values, which difference denotes the precision of the calculating model. This precision is heavily influenced by the heat conduction model, used between the fuel and the coolant. During the work five different conduction models were investigated, to determine which one offers more precise results. There was also a way examined to determine the uncertainty of the fuel temperature coefficient based on the outcome of the examined power transitions.
Calculations of spent fuel isotopic composition for fuel rod from VVER-440 fuel assembly benchmark using several evaluated nuclear data libraries
Authors: Blandinskiy V. Yu. , Dudnikov A. A.
Published: September 2018

This article presents a comparison of results of simulation of VVER-440 reactor fuel burnup by means of ISTAR set of tools using ENDF/B-VII.0 and JEFF-3.1 evaluated nuclear data libraries. Code verification is required on the basis of both experimental data and computational uncertainty analysis. A VVER-440 fuel rod burnup simulation using ENDF/B-VII.0 and JEFF-3.1 evaluated nuclear data libraries was performed as preliminary step before comparison of nuclear data uncertainty analysis and calculation/experiment. Fuel irradiation conditions and SNF nuclide composition experimental data were obtained from radiochemical assays of irradiated VVER-440 fuel report. Fuel burnup simulation was carried out by means of ISTAR set of tools using Monte-Carlo code for spectrum averaged reaction rates evaluation required for solution of Bateman's equations. As a result, Kinf and nuclide composition across burnup were estimated for the sample considered. On the basis of two nuclear data libraries’ implementation for depletion simulation it was shown that Kinf uncertainties rise across burnup from 0.4% at the beginning of life up to 0.7% at the end of life. Heavy nuclides composition uncertainties run up to 9.5% for Am-241 at the end of the 4th life time; however for main uranium and plutonium isotopes the uncertainties do not exceed 1.2%. Most fission products composition uncertainties stay below 7.3% except Sm-150 nuclide (15.1%). The next step will be a comparison with experimental spent nuclear fuel isotopic composition data considering the above mentioned uncertainties.
