The Influence of Zeolite (Sokyrnytsya Deposit) on the Physical and Chemical Resistance of a Magnesium Potassium Phosphate Compound for the Immobilization of High-Level Waste

The manuscript presents the results of the development of new material for high-level waste (HLW) management: the magnesium potassium phosphate (MKP) compound. The possibility of using zeolite (Sokyrnytsya deposit) to increase the mechanical, thermal, and hydrolytic resistance of this compound with immobilized HLW was studied. The main component of the used natural zeolite is a mineral of the clinoptilolite–heulandite series, and quartz, microcline, and clay minerals (illite, sepiolite, and smectite) are present as impurities. The compressive strength of the compound, containing at least 4.2 wt % zeolite, is about 25 MPa. Compound containing 28.6 wt % zeolite retains high compressive strength (at least 9.0 MPa), even after heat treatment at 450 °C. The adding of zeolite to the composition of the compound increases its hydrolytic stability, while the leaching rate of the mobile nuclides 137Cs and 90Sr decreases up to one order of values. Differential leaching rate of radionuclides from the compound containing 28.6 wt % zeolite is 2.6 × 10−7 for 137Cs, 2.9 × 10−6 for 90Sr, 1.7 × 10−9 for 239Pu, and 2.9 × 10−9 g/(cm2∙day) for 241Am. Thus, the properties of the resulting compound correspond to the requirements for solidified HLW in Russia

Solidification of high level waste using magnesium potassium phosphate compound

Compound samples based on the mineral-like magnesium potassium phosphate matrix MgKPO4 × 6H2O were synthesized by solidification of high level waste surrogate. Phase composition and structure of synthesized samples were studied by XRD and SEM methods. Compressive strength of the compounds is 12 ± 3 MPa. Coefficient of thermal expansion of the samples in the range 250–550 °C is (11.6 ± 0.3) × 10−6 1/°C, and coefficient of thermal conductivity in the range 20–500°С is 0.5 W/(m × K). Differential leaching rate of elements from the compound, g/(cm2 × day): Mg - 6.7 × 10−6, K - 3.0 × 10−4, P - 1.2 × 10−4, 137Cs - 4.6 × 10- 7; 90Sr - 9.6 × 10−7; 239Pu - 3.7 × 10−9, 241Am - 9.6 × 10−10. Leaching mechanism of radionuclides from the samples at the first 1–2 weeks of the leaching test is determined by dissolution (137Cs), wash off (90Sr) or diffusion (239Pu and 241Am) from the compound surface, and when the tests continue to 90–91 days - by surface layer depletion of compound. Since the composition and physico-chemical properties of the compound after irradiation with an electron beam (absorbed dose of 1 MGy) are constant the radiation resistance of compound was established.

Magnesium Potassium Phosphate Compound for Immobilization of Radioactive Waste Containing Actinide and Rare Earth Elements

The problem of effective immobilization of liquid radioactive waste (LRW) is key to the successful development of nuclear energy. The possibility of using the magnesium potassium phosphate (MKP) compound for LRW immobilization on the example of nitric acid solutions containing actinides and rare earth elements (REE), including high level waste (HLW) surrogate solution, is considered in the research work. Under the study of phase composition and structure of the MKP compounds that is obtained by the XRD and SEM methods, it was established that the compounds are composed of crystalline phases—analogues of natural phosphate minerals (struvite, metaankoleite). The hydrolytic stability of the compounds was determined according to the semi-dynamic test GOST R 52126-2003. Low leaching rates of radionuclides from the compound are established, including a differential leaching rate of 239Pu and 241Am—3.5 × 10−7 and 5.3 × 10−7 g/(cm2∙day). As a result of the research work, it was concluded that the MKP compound is promising for LRW immobilization and can become an alternative material combining the advantages of easy implementation of the technology, like cementation and the high physical and chemical stability corresponding to a glass-like compound

Temporality of law in light of axiology

The main point of that article is to consider the axiological aspect of legal temporality. The presupposition of authors is consideration of the legal framework as a specific type of social frameworks. The social temporality theory is applicable for characterizing the temporal modes of social reality. The category of time is discussed as a phenomenon determined by events in terms of the social temporality theory. The authors regard the category of legal time as a special kind of social time. Legal time becomes reality through rules of law, legal events and juridical facts. They function as reference points that shed light on the temporal processes in law. The category of legal time is essential for characterizing the specifics of legal relationships that remain fixed in the past, present and future. The kinds of time are of direct importance to law. These mentioned kinds exist in three temporal dimensions that are absolutes. The law links people and their destiny with the past, regulates the rules of conduct in the present and determines social changes in the future as well as what happens to a person possibly. Thus, the value of time and temporality determines the value of law. Consideration of legal time in the axiological dimension gives us possibility to overview the role of temporal factors in the formation and development of legal relationships

Исследование адаптационного потенциала в разных возрастных группах студентов в период пандемии

Introduction. This paper demonstrates the importance of studying adaptive potential in students during a pandemic and its parameters as a basis for mental health and psychological well-being. The authors describe the structure and key parameters of adaptive potential in their relation to hardiness. This study aimed to investigate associations of psychological flexibility as a predictor of adaptability with other manifestations of adaptation mechanisms. This paper brings new insights into the dynamics of adaptability at different stages of adolescence. Methods. The study sample comprised 67 students aged 18 to 24 years (Mean ± SD = 20.7 ± 1.8). Diagnostic instruments: (a) the Hardiness Survey by S. Muddy, (b) Young Schema Questionnaire, YSQ-S3R, (c) Ways of Coping Questionnaire, WCQ, by R. Lazarus, and (d) Clinical Questionnaire for Detection and Evaluation of Neurotic States by K. K. Yakhin and D. M. Mendelevich. All statistical analyses were performed using IBM SPSS Statistics 27 software. Methods of mathematical statistics: Pearson’s correlation coefficient, parametric Student’s t-test, and Mann–Whitney U-test for independent samples. Results and Discussion. Correlation analysis showed the existence of strong inverse correlations of hardiness with maladaptive schemas, including ‘vulnerability’, ‘distrust’, ‘submission’, ‘failure’, ‘rigid standards’, ‘dependence/helplessness’, and ‘defectiveness’, as well as neurotic states and coping strategies. Therefore, the authors identified two contradictory trends in adaptation to the COVID-19 pandemic in different age groups. The scales of early maladaptive schemas (EMS) and coping strategies have numerous positive correlations, except for the ‘decision planning’ strategy, which correlates negatively with certain schemas. The authors consider EMS as a manifestation of psychological rigidity, which reduces adaptive potential. The absence of pronounced maladaptive schemas increases adaptive potential. There is a positive age-related dynamics in the development of individual adaptation capabilities. The resistance indicator increases and the EMS manifestation decreases with age.Введение. Авторами доказывается актуальность изучения адаптационного потенциала студентов в период пандемии, выявления его параметров, как основы психического здоровья и психологического благополучия. Описана структура, ключевые критерии адаптационного потенциала в их связи с жизнестойкостью. Новизна исследования заключается в изучении связи психологической гибкости, как предиката адаптивности, с другими проявлениями адаптационных механизмов; изучении динамики показателей адаптивности на разных этапах юности. Методы. Приняли участие студенты в возрасте от 18 до 24 лет (Mean ± SD = 20,7 ± 1,8) в количестве 67 человек. Диагностический материал: тест жизнестойкости С. Мадди; схемный опросник Янга «YSQ-S3R»; опросник «Способы совладающего поведения» (WSQ) Лазаруса; клинический опросник для выявления и оценки невротических состояний (К. К. Яхин, Д. М. Менделевич). Статистическая обработка данных проводилась в программе SPSS Statistics 27 (IBM). Методы математической статистики: коэффициент корреляции Пирсона; параметрический t-критерий Стьюдента и U-критерий Манна – Уитни для независимых выборок. Результаты и их обсуждение. Корреляционный анализ выявил наличие сильных обратных корреляций жизнестойкости с дезадаптивными схемами «уязвимость» и «недоверие», «покорность», «неуспешность», «жесткие стандарты», «зависимость/беспомощность» и «дефективность», невротическими состояниями, копинг-стратегиями. В результате были определены две противоположные адаптационные тенденции к условиям пандемии в разных возрастных группах. Шкалы РДС и копинг-стратегии имеют многочисленные положительные связи, за исключением стратегии «планирование решения», которая имеет отрицательные связи с некоторыми обнаруженными в выборке схемами. Авторы рассматривают РДС как проявление психологической ригидности, снижающее адаптивный потенциал; отсутствие выраженных дезадаптивных схем повышает адаптационный потенциал. В заключение делается вывод о наличии положительной возрастной динамики в развитии адаптивных возможностей личности: с возрастом повышаются показатели жизнестойкости, снижаются проявления РДС

Production of High-Dispersed Palladium Particles on α-Al2O3 Nanoporous Microgranules by the Extractive-Pyrolytic Method

The extractive-pyrolytic method (EPM) was used for the production of composites based on nanocrystalline palladium. Nanoporous microgranules of α-Al2O3 prepared from a plasma-processed nanopowder of Al2O3, were used as a carrier. The organic precursor was prepared by extracting palladium from an aqueous solution using n-trioctylammonium chloride ((C8H17)3NHCl) in toluene. The influence of pyrolysis conditions on the phase composition and nanoparticle size of final products has been investigated. X-ray diffraction measurements demonstrated that the heating of samples to 300, 350 and 400 °C (heating rate 14 °/min) resulted in the formation of nanocrystalline palladium on a porous carrier with an average particles size of 15, 23 and 28 nm, accordingly. IR spectra of the above-mentioned samples did not show the presence of organic impurities. Thermal treatment at 250 °C allows to obtain palladium particles with a crystal size of 7 nm, but the complete decomposition of the organic part has not been achieved under such conditions. It has been found that composites produced at pyrolysis temperatures of 250-400 °C (2.5 wt.% Pd content) exhibit catalytic activity at the oxidation of glycerin by molecular oxygen. The study of magnetic properties has shown that the composite produced at 300 0C exhibits ferromagnetic properties
