The entry of postmodernism into world culture in the second half of the 20th century had a significant impact on many areas of art. As a result of the division of postmodernism into mutual directions, the separation of the aletorics and happening directions became the beginning of writing many works. The article provides information about the features of aleatorics and happening in such areas of art as drama, music, and discusses cases of manifestation in literature. Aleatorics and happening as artistic trends in art, occurring in the eyes of the audience and listeners, have their own technique of execution. In the process of identifying the features of the meeting of aleatorics and happening in the literature, attention is drawn to the philosophical essence and idea of these directions. The article reveals the image of a posthuman in two main directions of postmodernism under the influence of the environment, social situation, and the material world. Since aleatoric is based on the philosophical notion that life is governed by chance, the author tries to save the protagonist from unscrupulous structures, but is faced with subjective arbitrariness caused by other events. In happening, the posthuman in a world consisting of a series of random events is exposed to a freedom-loving image that subjectively feels complete freedom, but in fact is subject to fate. There are also mysterious, illogical actions of the characters. In most of the innovative works of Kazakh literature, there are features characteristic of aleatorics and happening. Considering that art depends on the social stability of society, it is natural that, in accordance with the ongoing changes in society and culture, the features of postmodernism also affect the literary work. To consider the manifestations of related trends in literature, the works of several writers were analyzed, examples were given.
Types of proverse in the works of Abay
Authors:   M.O.Auezov Institute of Literature and Art Almaty, Kazakhstan, Nabiolla N.
Published: January 2022

The article examines the "proverbs" in the works of the poet, which are an offshoot of Kazakh folklore. In the course of the analysis, the proverbs in the poet's work were considered in three stages. Initially, Abai Kunanbayev used folklore in his poems as a master of the art, a representative of aesthetics, a poet-thinker, in "words of edification" he studied folklore. At the same time, he viewed some of the proverbs as a representative of the people. This article discusses Abai's views on some of the proverbs and sayings that reveal their meaning, as well as the proverbs that are still used today. A number of Abai's proverbs are preserved in the manuscript heritage collected in the fund of the State Historical, Cultural and Literary Memorial Museum-Reserve "Zhidebay-Borili Abay" in Semipalatinsk. In these letters, written in Arabic, he praised the governor who ruled the country and settled disputes fairly. As a result of the study, it was established that these are the proverbs of Abai. The article clearly compares the dance to the hero and clearly shows the place and status of the dance for the country. We also looked at a proverb that compares the psychology of slavery to nobility, height, and depth of consciousness. Abai managed to convey human psychology at all levels of society. These proverbs are cited as examples in a research article. Of course, not all proverbs are as pure as gold. Some proverbs appeared in a certain period, within the framework of a certain ideology, in the interests of a certain group. Therefore, all this is considered the property of the people, but many of them fell out of use. Naturally, Abai Kunanbayev is critical of the ancient Kazakh heritage and, in turn, reveals the shortcomings of this heritage. Criticism of the use of some outdated ideas about the national heritage, including proverbs, by groups with certain views in their own interests, is mainly reflected in the poet's work. The article examines the poet's work and conducts research on the basis of the above three points.

Theater is a synthetic art. It creates performances full of mysteries, combining several arts. Although only actors appear before the public, it is no secret that hundreds of people are behind this. One of these performances is production of «Kyz Zhibek» at the K. Kuanyshbayev State Academic Kazakh Music and Drama Theater. Libretto by G. Musrepov, written based on the folklore source of the Kazakh people, staged by S. Kamiev.He tries to reveal the uniqueness of the work, which has become a masterpiece of Kazakh classics, finding modern directorial solutions and exploring the epic through the roles of actors. The features of each performer of the role are analyzed and identified. The value of the article is enhanced by the fact that the images created by the actors are analyzed taking into account the tastes of modern youth. At the same time, taking into account the tastes and needs of today’s public, the importance of musical and plastic solutions in the modern interpretation of classical works has not goneunnoticed by the authors.Th e historical and scientific value of the article is increased by the analysis of the first production of the libretto «Kyz Zhibek» with examples of director's decisions and the merits of acting.With the help of scientific analysis, the authors determined the place of the musical performance «Kyz Zhibek», staged specifically for the integration of songs and dances, in the theatrical repertoire. Researchers have also differentiated trends in the development of metropolitan art. Special attention of researchers is devoted to the issues of continuity between the young generation of actors and leading actors. The article uses an analytical approach that identifies modern trends in the development of Kazakhstani acting skills. The authors analyzed the performance taking into account S. Kamiev’s experience in staging musical performances. Considering other stage versions of the work, the researchers emphasize the originality of the performance of the K. Kuanyshbaev theater.
STIMOLARE LA PARTECIPAZIONE ALLA CONVERSAZIONE IN CLASSI CON LIVELLO ETEROGENEO DI SCOLARIZZAZIONE. LE PRATICHE DEL TEATRO SOCIALE PER SVILUPPARE SCOPI COMUNICATIVI REALI: L’ESPRESSIONE DI SÉ E L’INTEGRAZIONE
Authors: Canuto Claudia
Published: January 2022

Le interazioni nella classe di lingue sono sovente caratterizzate da una forte asimmetria e assenza di spontaneità che limita lo sviluppo della competenza d’uso in L2.  L’adozione di alcune pratiche del teatro sociale all’interno di percorsi glottodidattici permette di ribaltare tali dinamiche. In particolare, queste pratiche risultano funzionali nei contesti di italiano L2 per persone migranti in quanto permettono di inserire la persona nella vita sociale e comunitaria. Grazie alla pedagogia del teatro sociale i discenti diventano protagonisti degli scambi comunicativi ed esercitano un ruolo determinante nella scelta dei contenuti delle lezioni. Il presente contributo ha come obiettivo l’analisi delle dinamiche di interazione rilevate nel corso di due laboratori di teatro sociale rivolti a gruppi eterogenei di persone migranti. Per rilevare i dati e per verificare l’utilità delle attività si sono usati gli strumenti dell’Analisi della Conversazione. In particolare, l’analisi si è concentrata sulle forme della turnazione (le autoselezioni dei partecipanti, i turni dei registi), il contenuto dei turni, monitorando l’eventuale prossimità rispetto alle ordinarie conversazioni in classe (feedback correttivi, richieste di chiarimento) e le manifestazioni di attenzione alla forma (autocorrezioni, eterocorrezioni).

 

Stimulating participation conversations in classes with heterogeneous levels of schooling. Social theater practices to develop real communicative objectives: self-expression and integration

In language classes, interactions are often characterized by strong asymmetry and the absence of spontaneity that limits the development of proficiency in second language learning. The adoption of some social theater practices in language teaching can reverse these dynamics. These practices are especially functional in Italian language learning for migrants as they allow people to be included in social and community life. Thanks to social theater pedagogy, learners become protagonists of conversations and play a decisive role in choosing the content of the lessons. This paper aims to analyze the interaction dynamics observed during two social theater workshops for heterogeneous groups of migrants. Conversation analysis tools were used to collect data and verify the usefulness of the activities. In particular, the analysis focused on the forms of turns (the self-selection of the participants, the turns of the directors), the content of the turns, monitoring proximity to ordinary class conversations (corrective feedback, requests for clarification) and attention on form (self-corrections, heterocorrections).
«IL ROMANZO D’UN MAESTRO» DI EDMONDO DE AMICIS: PRIME INDAGINI SULLA LINGUA E LA SUA EVOLUZIONE
Authors: Del Mauro Miria Martina
Published: January 2022

L’articolo propone un’indagine linguistica sulla prima metà dell’opera de Il romanzo d’un maestro di Edmondo De Amicis. Dal punto di vista grafico, fonetico, morfologico, lessicale e infine sintattico, si opera un confronto tra l’edizione a stampa del 1900 (ultima vivente l’autore), con la prima edizione del 1890 e una versione autografa del testo, quest’ultima conservata presso la Biblioteca Civica L. Lagorio di Imperia. Nell’articolo si inquadrano i mutamenti intercorsi all’interno della teoria e della prassi linguistica del Nostro oltreché del panorama linguistico e della riflessione grammaticografica e lessicografica a lui coevi. Le scelte linguistiche di De Amicis sono state quasi sempre confrontate anche con quelle della Quarantana del Manzoni: il Nostro è sì manzoniano, ma non pedissequo, e con una autonomia di vedute nella formulazione di proposte linguistico-didattiche caratterizzate dall’uso del fiorentino coevo che si stempera nel toscano, nei classici e, sia pure limitatamente, nell’uso del dialetto. Nel Romanzo d’un maestro è dunque presente un eclettismo linguistico conciliativo, ravvisabile anche nelle pagine dell’Idioma gentile: nonostante il modello manzoniano risulti essere il preferito, tuttavia la sua apertura verso modelli alternativi smorza le più radicali implicazioni del pensiero del Maestro, dando ragione a chi ha riconosciuto il carattere moderato delle scelte linguistiche del Nostro.

 

Il romanzo d’un maestro by Edmondo De Amicis: preliminary investigations of language and its evolution

The paper proposes a linguistic investigation of the first half of Il romanzo d’un maestro by Edmondo De Amicis. From the graphic, phonetic, morphological, lexical and syntactic point of view, a comparison is made between the printed edition from 1900 (the last published during the author’s lifetime), with the first edition from 1890 and an autographed version of the text, conserved at the L. Lagorio Civic Library in Imperia. The article frames the changes that took place within De Amicis’s theory and linguistic practise as well as in the linguistic landscape and in the grammatical and lexicographic reflection of his contemporaries. The linguistic choices of De Amicis have almost always been compared with those of Manzoni’s Quarantana: De Amicis is Manzonian, but not slavish, and with an autonomy of views in the formulation of linguistic-didactic proposals characterized by the use of contemporary Florentine which dissolves into classic Tuscan and, to a limited extent, in the use of the dialect. In Romanzo d’un maestro there is therefore a conciliatory linguistic eclecticism, also recognizable in the pages of Idioma gentile: although the Manzonian model is the preferred one, its openness towards alternative models dampens the most radical implications of the Master’s thought, in agreement with those who recognized the moderate character of De Amicis’s linguistic choices.
APPUNTI PER UNA EDIZIONE DEL GLOSSARIO BERGAMASCO MEDIOEVALE DI ANTONIO TIRABOSCHI
Authors: Guerini Federica
Published: January 2022

Il presente contribuito descrive la struttura e i contenuti del Glossario Bergamasco Medioevale di Antonio Tiraboschi, attualmente conservato presso la Biblioteca Civica Angelo Mai di Bergamo, e costituito da quattro quaderni manoscritti e inediti, all’interno dei quali sono registrati oltre 2000 lemmi organizzati alfabeticamente. Si descrivono le fonti, edite e inedite, dalle quali Tiraboschi attinge i frammenti citati all’interno di ciascun lemma e si propone una classificazione delle annotazioni di cui il Glossario si compone in tre sottogruppi: 

note di carattere dialettologico, riguardanti gli esiti di forme latine o proto-romanze in italiano e nei dialetti gallo-italici (bergamasco, in primis) o relative alle particolari sfumature semantiche osservabili nel lessico del bergamasco;

annotazioni di natura linguistica sulla comparsa di costruzioni romanze in sostituzione delle costruzioni latine, e sulle innovazioni semantiche romanze ravvisabili all’interno dei frammenti citati ad esemplificazione di ciascun lemma;

osservazioni di carattere onomastico, relative a toponimi, microtoponimi e – più raramente – nomi personali.

L’analisi condotta rappresenta un passo preliminare alla realizzazione di una edizione digitale (consultabile in modalità Open access a partire dalla home page della Biblioteca Civica Angelo Mai) dei preziosi materiali linguistici di cui il Glossario si compone e di una corrispondente edizione cartacea, che favoriscano valorizzazione e la fruizione del lavoro svolto dallo studioso bergamasco.

 

Notes for an edition of Glossario Bergamasco Medioevale by Antonio Tiraboschi

This paper describes the structure and the content of Antonio Tiraboschi's Glossario Bergamasco Medioevale, currently preserved at the Biblioteca Civica Angelo Mai in Bergamo, consisting of four manuscripts and unpublished notebooks containing more than 2000 alphabetically organized headwords. The sources, both published and unpublished, from which Tiraboschi drew the fragments cited as part of each lemma are described and a classification of the annotations into three subgroups is proposed: 

notes of a dialectological nature, concerning either Latin or proto-Roman forms in Italian as well as in the Gallo-Italic dialects (Bergamasque, in primis) or relating to particular semantic nuances observable in the lexicon of Bergamasque;

linguistic notes on the appearance of Romance constructions replacing Latin constructions and questionable Romance semantic innovations in the fragments cited as examples of each lemma;

onomastic observations, concerning toponyms, microtoponyms and - more rarely - personal names.

This analysis is preliminary step towards creating a digital edition (available in Open access mode from the home page of the Biblioteca Civica Angelo Mai) of the precious linguistic materials which compose the Glossary and a corresponding paper edition, which will favor the valorization and fruition of the work carried out by the Bergamasque scholar.
Do Social Media Platforms Always Use Personal Data Lawfully?
Authors: Flint Jason
Published: January 2022

The article considers the principal concerns posed by the increasing influence of social media and analyses the potential and actual legal bases relied upon by selected platforms for the processing of personal data. Special reference is made to the EU General Data Protection Regulation (Regulation (EU) 2016/679). The article concludes that the application of those legal bases may be questionable in certain situations and that platforms may struggle to achieve the transparency and proportionality required by applicable rules.

Published: January 2022

ObjectiveTo develop a predictive model using the risk factors of gestational diabetes mellitus (GDM) and construct a predictive nomogram for GDM risk in women during early pregnancy.MethodsA prospective study was conducted in two tertiary hospitals among pregnant women with gestational age ≤14 weeks. Early GDM was diagnosed if an abnormal 100 g oral glucose tolerance test was detected using the Carpenter and Coustan criteria after an abnormal 50 g glucose challenge test. The factors included in the model were ACOG risk factors; maternal age; family history of hypertensive disorder in pregnancy; family history of dyslipidemia; gravida; parity; histories of preterm birth, early fetal death, abortion, stillbirth, and low birth weight; and glycated hemoglobin (HbA1c) levels. The predictive models for early GDM were analyzed using multiple logistic regression analyses. The nomograms were constructed, and their discrimination ability and predictive accuracy were tested.ResultsOf the 553 pregnant women, 54 (9.8%) were diagnosed with early GDM. In the integrated model, there was a history of GDM (adjusted odds ratio [aOR], 5.15; 95% confidence interval [CI], 1.82-14.63; P=0.004), HbA1c threshold ≥5.3% (aOR, 2.61; 95% CI, 1.44-4.74; P=0.002), and family history of dyslipidemia (aOR, 2.68; 95% CI, 1.37-5.21; P=0.005). The integrated nomogram model showed that a history of GDM had a high impact on the risk of early GDM. Its discrimination and mean absolute error were 0.76 and 0.009, respectively.ConclusionApplication of the predictive model and nomogram will help healthcare providers investigate the probability of early GDM, especially in resource-limited countries.

Coronavirus disease 2019 (COVID-19) is associated with a systemic inflammatory response that activates coagulation in symptomatic patients. In addition, a rare form of thrombosis has been reported in people who received the COVID-19 vaccine, most of whom were women younger than 50 years of age. Considering that hormonal contraceptive methods widely used by women of childbearing age increase the risk of thrombosis, the development of guidelines for the use of hormonal contraceptives in the era of the COVID-19 pandemic is necessary. In this context, the Korean Society of Contraception and Reproductive Health provides guidelines for issues regarding contraception and reproductive health during the pandemic.

ObjectiveTransvaginal removal of large specimens during laparoscopic hysterectomy can be a complex surgical procedure that poses a risk of organ injury and tissue spillage into the abdominal cavity and is associated with extraction of the specimen and manual morcellation. Our objective was to demonstrate a technique for transvaginal removal of large specimens using the Alexis Contained Extraction System (CES) in laparoscopic hysterectomy.MethodsThe technique used for transvaginal removal of large specimens using the Alexis CES was presented in this video. Surgery was performed at a tertiary hospital.ResultsFollowing resection of the specimen during laparoscopic hysterectomy, the Alexis CES was inserted into the abdominal cavity through the umbilical trocar wound. The specimen was placed in a bag to prevent tissue spillage. The ring retractor was guided to the vagina and pulled out transvaginally. By repeatedly turning the ring retractor, tension was applied to the specimen bag, and the vaginal wall was unfolded all around to enable a secure surgical field. During manual morcellation of the specimen in the bag, the retractor was pulled and additionally turned to roll and re-tension the specimen bag when the bag was loosened. The specimen was pushed out of the vagina and safely and effectively extracted without concerns about tissue spillage in the abdominal cavity or related organ injuries.ConclusionThe technique for transvaginal removal of large specimens using the Alexis CES enables simple, effective, and safe tissue extraction with contained manual morcellation during laparoscopic hysterectomy.

Regional autonomy refers to the authority that regulates the community's interests or acts as a regulator in areas where the federal government empowers local governments to manage their own government. This research technique utilizes five book sources in order to learn about regional autonomy, its various forms, and legal foundations. Community engagement in governance, particularly at the village level, is one of the foundations of regional autonomy that requires attention in this regard. Concerning the village government system's role in development implementation, many village development initiatives have been conceived and determined primarily on considerations and techniques from above, without involving the community being developed.

Nigeria has been identified as one of the largest active users of gasoline generators globally. Due to the widespread incessant use of gasoline generators, the present study assessed the exposure to gasoline generator emission (GGE) and some toxicity endpoints. This study employed a laboratory-based experimental design. An emission chamber was designed using clear thermoplastic to house the rats during exposure to 0.5KVA GGEs. Three experimental groups, each with eight rats respectively, were subjected to 5, 10, 15 minutes of of daily GGE exposure for fourteen days for fourteen days, while the fourth was a control group. Selected air quality parameters were measured using the appropriate samplers. Assays like liver function tests, antioxidant enzyme activity, and micronucleus frequency were conducted after the experiment. Micronucleus frequency significantly increased with time of GGE exposure (p=0.000), while the liver tissue antioxidant activity of the test groups was significantly higher than that of the control group (p<0.05). Moreover, histopathological examinations revealed lesions like sinusoidal congestion and vacuolar degeneration of the hepatocytes in liver tissues of the exposed rats. However, the liver function test showed a non-significant association with their level of GGE exposure. The result of this study suggested that exposure to GGEs at a non-lethal concentration in a sub-acute or chronic manner has deleterious effects on mammalian biochemical systems. Therefore, the use of exhaust filters and improvement in the ventilating systems of houses are encouraged to reduce exposure rates in developing countries like Nigeria, where GGEs are widespread due to erratic electricity supply.

Depression is a negative cognitive triad that consists of alternating amounts of alienation. In addition, this generally leads to inaction, remorse, lack of focus, societal disengagement, sleep disruptions, and suicidal impulses. The cross-sectional descriptive study intended to analyze depression and ascertain the influences of depression among 439 undergraduate students. These pupils were attending their second semester of the academic year 2020, Nakhon Pathom province, Thailand. Research instruments were self-report questionnaires, the 9-item patient health questionnaire, the Parenting Style Questionnaire, the Rosenberg’s Self-Esteem Scale, and the revised Multi-dimensional Scale of Perceived Social Support. The Cronbach's alpha reliabilities comprised .85, .69, .72 and .92, respectively. Descriptive statistics and stepwise multiple regression analysis examined the data gathered. Results revealed that the mean score of depressive symptoms was 6.51 (SD = 4.27), which was minimal depressive symptoms. Authoritarian parenting style was the best significant predictor (β = .316), the second-best was social support (β = -.237), and the third-best was self-esteem (β = .104). The three predictors accounted for 20.7 % (F3, 435 = 37.837, p < .001) in the prediction of depressive symptoms among undergraduate students. Moreover, the findings recommended that healthcare providers and school workers should plan activities or interventions for undergraduate students. Consequently, they should encourage self-esteem, social support and cultivate appropriate parenting styles. As a result, depressive symptoms would decline.

Published: January 2022

High-power intense heat exchange devices found wide circulation in the world industry. One of types of such heat exchange devices are the furnaces of fire heating which are widely used in oil processing and chemical branch. Because of considerable heterogeneity of temperatures in their combustion chamber, there is an overheating of a part of pipes, which is followed by the increased coke production on the surfaces of heat exchange contacting to oil products. And, as a result, reliability of operation of the equipment, its resource of work and efficiency of oil processing decreases. In work the design of heat exchange pipe of the furnace fire heating with use the eutectic alloy of lead with bismuth is offered. The design represents the "pipe in a pipe" heat exchanger which ring gap is filled with the eutectic alloy of lead with bismuth, fire heating is carried out from an external surface, oil products settle down in an internal pipe. With use of numerical modeling in an OpenFOAM CFD package comparative estimates of distribution of temperatures on the heat exchange surface contacting to oil products for a "traditional" heat exchange pipe and a design of the pipe offered by authors in the conditions of uneven fire heating from an external surface are carried out, results of calculations are presented. It is shown that the pipe design offered by authors promotes alignment of temperature fields on the section of heat exchange pipe.

Published: January 2022

In the present work the digital data on decay curves of delayed neutron intensity, measured for the fission of 235U, 238U and 239Pu by thermal and fast neutrons, is presented. The estimation of time parameters of delayed neutrons in 6 and 8 groups representation have been made on the base of individual experimental series using iterative least squares technique. It have been shown, that uncertainties of the parameters estimation in the 8 group representation, obtained on the basis of the experimental data are comparable with the uncertainties of the 6-group representation. The experimental data measured in the wide range of the time after the end of irradiation - (0,1-700 s) are of significant interest for intercomparison and validation of the different mathematical methods and programs, used for the processing of the decay curves of delayed neutron intensity, and also for analysis of the experimental data in the process of formulating of the evaluated data on relative abundances and half-lives of the delayed neutron precursors for the wide range of the fissioning nuclides.
CORRECTION OF INVERSE POINT KINETICS EQUATIONS FOR MEASUREMENT REACTIVITY IN THE PROMPT JUMP APPROXIMATION
Authors: Abramov B
Published: January 2022

We consider methods for calculating the reactivity of a nuclear reactor from the measured dependence of the neutron flux in the reactor on time, based on the use of the inverse point kinetics equations, which relate the values of reactivity and neutron flux in the reactor. The main attention is paid to the correction of the equations of inverse point kinetics in the prompt-jump approximation (or in the theory of singular perturbations for equations with a small parameter with the highest derivative). The nonequivalence of the corresponding problems for the direct and inverse point kinetics equations in the prompt-jump approximation is noted, which consists in the fact that, contrary to expectations, the reactivity values appearing in these problems do not generally coincide with each other. The reasons for this non-equivalence are investigated and ways to eliminate it are considered. New inverse point kinetics equations are proposed in the prompt-jump approximation, devoid of the indicated disadvantage of the traditional equations. These equations are tested by substituting in them analytical solutions of the corresponding (direct) Cauchy problems for point kinetics equations using the apparatus of the theory of systems of ordinary differential equations, adapted to the problem in question. It is shown that the use of the equations proposed in the work leads to the correct determination of reactivity immediately after the instantaneous introduction of a disturbance into the reactor, and not in asymptotics, as is usually the case when applying traditional equations.
UPGRADING OF CORE DESIGN SOFTWARE
Authors: Adeev V
Published: January 2022

The tightening of safety requirements leads to the introduction of new boundary and framework parameters for the characteristics of the core. The selection has become much more complicated, because it is necessary to consider the fulfillment of criteria for the effectiveness of emergency protection, a separate organ and a working group of CPS, the temperature of repeated criticality, etc. The use of burnable absorber does not allow you to estimate the energy release peak factors only at the beginning of fuel cycle, analysis is required during the entire time of its burning, because the change of peak factors is non-monotonic. New limits on energy release have been introduced that require the performance of fuel cell calculations - linear load of fuel rods depending on their burn-up. The correct choice of reactor core determines the success of its operation during the whole year. The choice is complicated and subjective and depend on the skill of the designer. The paper focuses on the implementation and application of evolutionary strategies and genetic algorithms (ES and GA) to optimize the core pattern of VVER reactors. A method of formalizing the core pattern when using ES and GA is described. A scheme for selecting options, performing calculations and displaying results is shown. Methods of graphical representation and results of core pattern search with maximum reactivity margin for different criteria are described. Methods for reducing the search space, ensuring the finding of a global optimum and reducing the number of calculations using heuristics and neural networks are proposed. The author has developed a program for optimizing core pattern of VVER using ES and GA. The program is used in the design of fuel cycles and selection of core pattern at nuclear power plants. The program allows you to reduce labor costs, find a better core pattern, objectively assess the impact of boundary and framework safety parameters on the result of the choice.

The aim of the work is to study the possibility of long-term management of a developing or non-developing nuclear power system. The concept of fuel supply control is introduced. Nuclear power systems with different structural organization of generating capacities and a closed nuclear fuel cycle are considered. A comparison is made of these systems in terms of their development potential, ratio between the number of thermal and fast reactors and the possibilities of fuel supply. It is noted that the ratio is determined by the breeding characteristics, the balance of plutonium and natural uranium in the system, as well as the needs for NP development. A feature of the two-component systems of nuclear reactors considered in the work, consisting of thermal reactors of different types and fast reactors BN-1200, is that the SNF stocks of all types of reactors are completely processed during the considered time interval and all the excess separated plutonium is used to manufacture MOX fuel. The requirements to the characteristics of fast reactor breading are put forward. The important role of mastered and promising technologies with the possibility of their flexible adaptation to changes in the nuclear power development scale and rate is emphasized. It is shown that the system including advanced fast neutron sodium reactors having flexible breading can offer increased tolerance to possible changes in the nuclear power development rate. The results of simulation of fuel cycle scenarios for the considered two-component nuclear energy system are presented.

The BOR-60 reactor is actively used for conducting irradiation experiments in support of nuclear reactors both under operation, construction and design. Most of these experiments are conducted in the reactor core using various types of irradiation rigs. However, in recent years there has been keen interest in conducting reactor tests in the BOR-60 blanket. This is associated with several factors: the availability of blanket cells, weak influence on the reactor neutronic characteristics and safety, wide range of irradiation conditions (temperature, neutron flux density, damage doses, neutron spectrum), and cost of irradiation. The experience in BOR-60 blanket computational and experimental studies showed an ill agree-ment between the calculated and experimental neutronic characteristics. In addition to no orientation of the samples under study relative to the core center, there is a significant radial non-uniformity in the neutronic characteristics distribution in the BOR-60 blanket that limits its application for experimental studies. Therefore, detailed computational and experimental studies of the spatial-energy distribution of neutrons in the BOR-60 steel blanket is an important and urgent task.

To address the growing demand for isotopes, it is planned to use irradiation devices in high-power fast sodium reactors. With the help of this type of irradiation devices, mass production of the necessary isotopes is assumed. The designs of irradiation devices for operating time of cobalt-60 isotope in BN reactors are presented. A new version of the irradiation device for use in a high-power sodium fast reactor is proposed. The comparison of different variants of irradiation devices according to the obtained specific activity is given. The new design of the irradiation device combines the retarder units and the steel protection developed for the BN-600 in a single assembly. It allows to achieve cobalt activity of 150 Ci/g for a campaign of fuel (5 years). The results of a study of the azimuthal and radial distribution of the cobalt-60 formation speed to ensure the effective production of the product in a high-power reactor are presented. According to the results of the azimuthal distribution of the neutron capture rate, there is an uneven propagation in the horizontal section of the irradiation device. The maximum capture rate is shifted to the periphery of the irradiation device facing the center of the core. The obtained spatial distribution of the capture rate indicates the possibility of further work to create a more efficient design of the irradiation device for the conditions of a large fast reactor.

One of the key tasks for the reactor SVBR-100 project is substantiation of the core elements performance and efficiency. As part of the R & D program to justify the project, a significant amount of work was performed, which confirmed the corrosion resistance of the material of fuel rod claddings (ferric-martensitic (FM) steel) on the basis of 50 thousand hours, the consequences of deviations of the oxygen regime of the coolant from the optimal values were considered. Paper presents the main results of the analysis of fuel rod claddings loading conditions under normal operation, in violation of normal operating conditions and in conditions of hypothetical emergency overheating. It is concluded that the main mechanisms of damage to equipment and core elements in emergency and preemergency situations are associated with the degradation of strength properties with increasing temperature, while corrosion-erosion processes that accelerates with increasing temperature proceed relatively slowly and are limited in time of exposure. Based on the experimental data obtained in the justification of the SVBR project, the nature of the most dangerous emergency processes and the analysis of their consequences, the paper presents proposals for the formulation of key safety criteria for lead-bismuth reactor plants. The approach is based on the establishment of the maximum permissible temperature-time dependences and/or calculated residual deformations of fuel rod claddings made of FM steel.

Described are state-of-the-art approaches to solving the problems associated with impact testing of the equipment under development at the design stage. A brief description is provided of an experimental facility that models in different directions the impact loads equivalent to the effect of a blast wave originated near the object. The topicality is emphasized of developing - based upon the calculational mathematical analysis - the safe process tooling that prevents any possibility of accident consequences. The capabilities of ANSYS/LS-DYNA, a state-of-the-art computing system, are elucidated in brief. In ANSYS/LS-DYNA, full-scale mathematical 3D-modeling is implemented that enables a sufficiently deep and detailed analysis of dynamic processes through the use of a finite element method. Described are analytical and experimental methods of studying the deformation models of structural materials under static and dynamic loads, and determined are parameters of the mathematical models (Jonson-Cook models, Allen model, Rule & Jones, Cowper-Symonds model) from the LS-DYNA library. With account of the safety requirements in the regulatory documents, the deformation criteria are employed to assess the dynamic strength of the structural materials used to manufacture the tooling. Following the results of the mathematical analysis of the impact action, the tooling has been designed that enables successful testing at a safe level. The specified parameters have been reached that are in the technical requirements for the developed equipment - the obtained accelerations are maximally close to the calculated ones. Thanks to the integrated approach to the computational analysis that covered the engineering-and-design, physical-mechanical, mathematical and regulatory aspects, an opportunity has come to abandon the excessive conservatism and thus to fit well into the specified overall dimensions of the item and to reduce the specific metal content of the final product. Abandoning the multivariate progressive approximations in the analysis of the tooling at the design stage resulted also in the shortened design time and in the reduced design cost.
PARTIAL NEUTRON TRANSPORT EQUATIONS

Published: January 2022

To analyze the spatial kinetics of the reactor, a system of equations for the spatial kinetics of the reactor, consisting of two equations, is usually used. One of them describes the behavior of the neutron flux density, and the second describes the behavior of the precursors of delayed neutrons. In this case, the density of the neutron flux includes the flux density prompt neutrons, appearing directly upon fission of the nucleus, and delayed neutrons that appear in the decay of some fission fragments. This system of equations is called classical. This paper considers the possibility of representing the neutron flux density in a nonstationary process by individual equations for prompt and delayed neutrons and presents the initial results of modeling the nonstationary process for dumping a control rod in a fast medium-power reactor. A system of equations describing such a behavior of the neutron field in a reactor is called a system of partial equations.
