Development of CASMO5 for VVER-1000/1200 analysis and preliminary validation using critical experiments
Authors: Ferrer R. , Hykes J. , Rhodes J.
Published: September 2019

Studsvik has recently extended the CASMO5 advanced lattice physics code for the analysis of VVER 1000 and 1200 reactors. These extensions form the basis of CASMO5-VVER, which is primarily intended to compute homogenized nodal data for SIMULATE5-VVER. CASMO5-VVER leverages the latest nuclear data and numerical methods to VVER analyses. The current CASMO5 data library, based on the ENDF/B-VII.1 nuclear data evaluation, features a 586 energy group structure and nuclear data for hundreds of unique nuclides. Resonance self-shielding, based on the Equivalence Theory and an Optimal Two-Term Rational (OTTR) method, has been extended to support hexagonal geometry. The solution to the two-dimensional transport equation is based on the new Linear Source (LS) approximation for the Method of Characteristics (MOC). The acceleration of the MOC solution is attained through the implementation of a Coarse-Mesh Nonlinear Diffusion (CMND) acceleration. Results from preliminary validation against various critical experiments are presented in this work.

Leningrad NPP-2 start-up loss of power test and its simulation with use of KORSAR/GP code
Authors: Suslov M. V. , Petkevich I. G. , Uvakin M. A.
Published: September 2019

The paper deals with the results of the Leningrad NPP-2 start-up loss of power test and its simulation with use of KORSAR/GP code. The test was held at the 1st unit with VVER 1200 reactor on the 29th of March. During the test the steam generators were refilled with EFW system at first. This system is connected to the SG steam space. Therefore, injection of water leads to the secondary pressure decrease. This phenomenon is difficult for simulation due to complicated structure of the SG internals. Also, the test provides unique data for the reactor facility cooldown at natural circulation in the primary circuit. The important data for reactor head and pressurizer cooldown were obtained. Thus, the test data provides the validation of several processes such as: emergency feedwater injection into the steam generator; steam generator filling with “cold” water from AFWS; pressure regulation at filled pressurizer; cooldown of the reactor head and the coolant circulation beneath the head. The results of the test were used for the validation of KORSAR/GP code, unit nodalization and equipment models.
Statistical evaluation of C-15 cycles in Paks NPP, based on measured in-core data
Authors: Horváth M. , Pós I. , Parkó T.
Published: September 2019

After a preparation period with VERONA upgrade and lead test assembly program, a new fuel type was introduced at MVM Paks NPP Ltd. This 4.7% average uranium enriched assembly type, together with the former 4.2% uranium enriched fuels, allowed us to lengthen the operating cycles to 15 months. Both fuel types contain gadolinium burnable poison, in six and three pins respectively. All of the four units have been converted to the C15 cycles, and have been being operated without any problems in the last few years. In this paper the test results of core design code HELIOS/C-PORCA, which is the basic model of VERONA, are outlined. C15 cycles were entirely investigated with the comprehensive study of measured and predicted (calculated) values of different reactor states. At first step, in order to prove the capability of the reactivity calculation of the nodal diffusion model, critical boric acid concentrations of different burnup and start up states were calculated and compared with measured values. During the next step of the verification process local in-core parameters were investigated. Measured neutron flux distributions (SPND signals) and coolant outlet temperatures were examined. SPND and thermo couple (TC) signals were predicted as a part of the monitoring system. The results of statistical investigations (average differences and standard deviations) for the applied fuel types are also presented.

Published: September 2019

Currently, new types of fuel are being considered to be introduced or already in the introduction process at Ukrainian NPPs with WWER. By means of a new version of the TRANSURANUS code, new functions of the gas gap thickness in dependence on the burnup have been created and implemented into the gas gap model of the reactor dynamics code DYN3D. These new functions cover all actual and perspective fuel types for the Ukrainian NPPs with WWER.
VVER-1000 fuel assembly model in CAD-based unstructured mesh for MCNP6
Authors: Lovecký M. , Závorka J. , Vimpel J.
Published: September 2019

Geometry models for Monte Carlo transport codes have been using standard constructive solid geometry (CSG). The standard approach is using analytical equations for defining surfaces from which spatial cells are constructed. However, this approach can be quite time consuming and possibly error prone for complex models. Monte Carlo transport codes are continuously developed, one of the paths is using CAD-based mesh geometry. MCNP6 features unstructured meshes (UM) created with Abaqus/CAE as geometry description. Attila4MC package for creation of UM geometry from CAD model can be used for MCNP6 models. VVER-1000 fuel assembly model in UM geometry was created for TVSA-T.mod.2 fuel type. Basic validation of the model was performed, initially for criticality calculations. In the future, the model will be used for criticality safety analyses, preparation of boundary conditions for diffusion codes and radiation shielding analyzes of spent fuel transport and storage facilities.
Covert channel implementation using motion vectors over H.264 compression
Authors: Segal Yoram , Hadar Ofer
Published: September 2019

Embedding information inside video streaming is a hot topic in the world of video broadcasting. Information assimilation can be used for positive purposes, such as copyright protection. On the other hand, it can be used for malicious purposes such as a hostile takeover, remotely, on end-user devices. The basic idea of information assimilation technology within a video is to take advantage of the sequence of frames that flows between the video server and the viewer. Casting foreigner data into each frame such a hidden communication channel is created namely - covert channel. Attackers find the multimedia world in general and video streaming, an attractive backdoor for cyber-attacks. Multimedia covert channels provide reasonable bandwidth and long-lasting transmission streams, suitable for planting malicious information and therefore used as an exploit alternative. In this article, we propose a method to protect against attacks that use video payload for transferring confidential data using a covert channel.  This work is part of a large-scale study of video attack methods. The goal of the study is to build a generic platform that will investigate the reliability of video sequences. The platform allows to encoding and decoding video. A plugin can be added to each encoder or decoder. Each plugin is an algorithm that is studied and developed in the framework of this study. One of the algorithms in this platform is information transmission over video using motion vectors. This method is the topic off this article.
Moroccan armed forces in the face of geopolitical mutations
Authors: Houdaigui Rachid EL
Published: September 2019

One of the first sovereign decisions of independent Morocco was to create the Royal Armed Forces (FAR) on 14 May 1956. Since then, the mission of the Moroccan army is consistent with the country's historical continuity shaped by strategic constants, it has however been subject to both conceptual and operational pressures since the late 1990s, as the lines between defense and security have blurred.  This paper explores the central issue of adjusting the Royal Armed Forces (FAR) to a rapidly changing world.  It examines two dynamics from a comparative perspective: strategic prioritization in support of defense policy adjustment and the defense-security continuum at the heart of FAR doctrine.
The strategic planning of the National Power: a vision from the National Defense
Authors: Carmona Ronaldo G
Published: September 2019

The key elements of national power is a recurring theme in the debate on international relations, appearing in classical writers such as Morgenthau and Kenneth Walt. In Brazil, the theme of the elements of National Power was formulated mainly within the scope of the Brazilian War College (ESG). The following text seeks, firstly, to introduce the reader into the planning system structured by the Brazilian State as of the 1930 Revolution. Next, he specifically addresses the geopolitical contribution to this debate for a third and last part, to discuss the evolution of Brazilian Defense policies and strategies, relating them to the debate on national construction and the national development project. In this last part, the article is aimed at identifying and discussing the main vectors that show changes in the Brazilian national strategy observed from the key points of the main official documents. It is, therefore, a work that seeks to discuss, essentially, the contribution of the Brazilian Armed Forces to the national planning system, demonstrating how this participation has been decisive in the construction of the Nation.
Particle mass and gaseous emissions from small scale modern wood stoves
Authors: OBAİDULLAH Md.
Published: September 2019

The objectives of the paper were to evaluate
particle mass concentrations of PM1 (size <1 µm) and PM2.5
(size <2.5 µm), mass size distributions and CO emissions under standard
laboratory conditions obtained from two commercially available modern
residential wood stoves with capacity 10 kW and 20 kW. Four combustion batches
with minor modification of primary air flows into the combustion chamber for
each stove were conducted to evaluate the emission results. Particle mass
concentrations and size distributions were measured in real time using an
Electrical Low Pressure Impactor Plus (ELPI+) instrument, which measures
particles with a fast response time in a wide particle size range from 6 nm to
10 µm aerodynamic diameter. Gaseous concentrations of O2 and CO2
were measured continuously using a Horiba PG-250 analyzer and CO emissions were
measured using a Siemens Ultramat 6 gas analyzer. The measurement protocols of
each combustion test were conducted according to the European standard EN
13229. The combustion experiments were conducted in a laboratory of a stove
manufacturing plant in Belgium. The results showed that PM1 and PM2.5
concentrations of all the batches of both stoves varied from 116 to 327 mg/Nm3
and 139 to 413 mg/Nm3, respectively in the combustion cycle.
Particle mass size distribution for all batches from both stoves is very
similar showing a maximum in the fine mode at a particle size of around
330 nm to 500 nm. The CO emissions from all the batches varied from
447 to 1184 mg/Nm3 for the 10 kW stove and 958 to 1545 mg/Nm3
for the 20 kW stove. The experimental results of PM1, PM2.5
concentrations and CO emissions from combustion measurements could be useful
for the improvement of the combustion process as well as the reduction of
gaseous and particle mass emissions from these residential biomass combustion
appliances.

On the use of aqueous solutions of polyvinyl methyl ether for the embolization of blood vessels
Authors: Ignatieva P. E. , Zhavoronok E. S. , Legonkova O. A. , Kedik S. A.
Published: September 2019

Aqueous solutions of polyvinyl methyl ether were investigated in order to test whether it is possible to utilize them as bases for embolic agents used to deliberately block blood vessels. This may be necessary in the course of treatment of vascular abnormalities, tumors, as well as during the preparation of patients for surgery. The right branch of the binodal curve for the binary system “polyvinyl methyl ether–water” was drawn using the cloud point method and the lower critical mixing temperature (35.5 °C) was calculated. Furthermore, the exact concentration of polyvinyl methyl ether in aqueous solutions at which phase transition occurs (given the temperature of 35.5 °C) was found to be 30 wt %. The viscosity–velocity curves for the 30% solution of polyvinyl methyl ether, obtained by rheoviscometry in the temperature range of 5 to 36 °C, indicate that this aqueous solution has a low viscosity and behaves like a Newtonian fluid. However, at the temperature of 35 °C and higher, close to the phase transition, a significant deviation from its Newtonian behavior is observed due to precipitation of polyvinyl methyl ether as it forms a solid white mass. Through the use of the Arrhenius–Frenkel–Eyring equation, the activation energy of the viscous flow for polyvinyl methyl ether solutions was found to be 31 kJ/mol. Based on refractometry data, it was demonstrated that phase transition in aqueous solutions of polyvinyl methyl ether is reversible. This feature can facilitate medical equipment cleaning before introducing the embolic agent into a patient’s bloodstream. Finally, the investigation determined some parameters, in which the formation of embolic agents from a 30% polyvinyl methyl ether aqueous solution occurs (in situ in a blood vessel at a temperature of 35.5 °C).

This work presents the results of a study of the resins of seven Ancient Egyptian mummies from the collection of the Pushkin State Museum of Fine Arts using a complex of analytical methods: gas chromatography, atomic emission and mass spectrometry. Natural bitumen and beeswax were identified in the resins using the gas chromatography–mass spectrometry method. Based on the results of hydrocarbon distribution in the profiles of n-alkanes in the resin coatings of the mummies and naturally occurring bitumen, it was assumed that the Dead Sea bitumen was used. The gas chromatography–mass spectrometry studies of mummy resins in the selected ion mode (m/z 217 and 191) provided additional evidence of the bitumen’s geographic origin. Atomic emission spectrometry with inductively coupled plasma was used as a means to determine the content of microelements. Vanadium, nickel and molybdenum were found in the tar of five mummies. The determined relative amounts of vanadium, nickel, and molybdenum in the resins of the studied mummies showed a good correlation with the available data on the content of these elements in the Dead Sea bitumen, as well as the Fayum mummy resin based on this bitumen. The advantages of using the method of identifying bitumen in mummy resins based on relative content of vanadium, nickel, and molybdenum were revealed.

On the origin of the oldest borrowed Christian terminology in Icelandic
Authors: Tarsi Matteo
Published: September 2019

This article deals with the origin of the oldest core of borrowed Christian terminology still extant in Icelandic, i.e. those words which were introduced in Old Norse in the period ranging from the first evangelical missions in Scandinavia (9th c.) to the establishment of the archbishopric in Niðarós (1153). After a short introduction (1), a brief overview of the aforementioned historical period is given (2). The corpus, which consists of 45 words, is subsequently presented alongside its semantic classification (3), of which a chronological (text-based) reading is given. In the next section (4), particular attention is drawn to a sample of ten words, which have been chosen for their importance both from a historico-linguistic and etymological perspective. Special emphasis is placed on addressing the role of Old Saxon in the dawn of Christianity in Scandinavia and Iceland and on revising some of the etymologies proposed by the three major Icelandic etymological dictionaries (AeW, IeW and ÍOb). In the final section (5), it is stressed that a methodology which rests upon historical, alongside linguistic and philological, facts is needed if one wants to better understand the cultural and linguistic background of a particular portion of the lexicon: here, the oldest part of the borrowed Christian lexicon is analysed as a particularly interesting example.
Algorithm for dynamic route assignment in complex street layouts
Authors: Деркач М.В. , Скарга-Бандурова І.С.
Published: September 2019

In some scenarios, public transport vehicles do not have permanently fixed routes that make it hard to implement optimal automatic routing techniques and use forecasting algorithms. To solve the problem of route destination, a mathematical model of the dynamic route assignment is developed. It is based on the graph model of the street layouts and includes the results of the arrival of vehicles in certain points. The proposed algorithm enables to dynamically recalculate the routes, depending on the intersection of the four types of nodes representing the key points of the transport network. A case study for the route assignment in city of Severodonetsk is discussed.

Research in the marine field is important to look at the state of the ocean's atmosphere and the biodiversity that can live in it. Based on the CalCOFI data set, seawater salinity correlates with the depth of the sea. Sea water salinity can be predicted based on its depth. The classic method that is often used is the least squares regression. Deep neural network is one of the machine learning methods that has been widely applied to regression problems. This study aims to find better predictive performance by comparing the least squares regression method and the deep neural network method. The research method is done first by making an equation model with the least squares regression method. Second, by training the deep neural network using the same data so that the network model is obtained. Furthermore, the results of both methods are compared by calculating MAE and MSE. The results showed that the network model with superior deep neural network was used to predict data outside the range of trained data compared to the least squares regression method.

A three-year experiment evaluated the beneficial effects of independent and combined practices on thermal conditions inside high tunnels (HTs), and further investigated the temperature impacts on lettuce production. Specific practices included mulching (polyethylene and biodegradable plastic films, and vegetative), row covers, cover crops, and irrigation with collected rainwater or city water. The study conducted in eastern Tennessee was a randomized complete block split-split plot design (RCBD) with three HTs used as replicates to determine fall lettuce weight (g/plant) and lettuce survival (#/plot), and the changes in soil and air temperature. The black and clear plastic mulches worked best for increasing plant weight, but when compared to the bare ground, the higher soil temperature from the plastics may have caused a significant reduction in lettuce plants per plot. Moreover, the biodegradable mulch did not generate as much soil warming as black polyethylene, yet total lettuce marketable yield was statistically similar to that for the latter mulch treatment; while the white spunbond reduced plant weight when compared with black plastic. Also, row covers provided an increased nighttime air temperature that increased soil temperature, hence significantly increased lettuce production. Cover crops reduced lettuce yield, but increased soil temperatures. Additionally, irrigation using city water warmed the soil and provided more nutrients for increased lettuce production over rainwater irrigation.
The Effect of Chromosome Structure upon Meiotic Homologous and Homoeologous Recombinations in Triticeae
Authors: Naranjo Tomás
Published: September 2019

The tribe Triticeae contains about 500 diploid and polyploid taxa, among which are important crops, such as wheat, barley and rye. The phylogenetic relationships, genome compo-sition and chromosomal architecture, were already reported in the pioneer genetic studies on these species, given their implications in breeding-related programs. Hexaploid wheat, driven by its high capacity to develop cytogenetic stocks, has always been at the forefront of these studies. Cytogenetic stocks have been widely used in the identification of homoeologous relationships between the chromosomes of wheat and related species, which has provided valuable information on genome evolution with implications in the transfer of useful agronomical traits into crops. Meiotic recombination is non-randomly distributed in the Triticeae species, and crossovers are formed in the distal half of the chromosomes. Also of interest for crops improvement is the possibility of being able to modulate the intraspecific and interspecific recombination landscape to increase its frequency in crossover-poor regions. Structural changes may help in this task. In fact, chromosome truncation increases the recombination frequency in the adjacent intercalary region. However, structural changes also have a negative effect upon recombination. Gross chromosome rearrangements produced in the evolution usually suppress meiotic recombination between non-syntenic homoeologs. Thus, the chromosome structural organization of related genomes is of great interest in designing strategies of the introgression of useful genes into crops.
