- ПубликацияТолько метаданныеAssessment of the impact of diversification of uranium switching on the risk of its non-energy use(2019) Glebov, V.; Глебов, Василий Борисович© 2018 Elsevier Ltd The main objective of the IAEA verification activities is the timely detection of the switching of a significant quantity of nuclear material (NM). However, from the point of nuclear security the multiple switching of “small” quantities of nuclear material with the aim of their subsequent collection also constitutes one of the main threat to ensuring the exceptionally peaceful use of nuclear materials. In this article this threat assessments were performed under the scenario of diversification of uranium switching. It is shown that diversification of 4%-uranium switching can lead to a substantial increase (up to 30 times) of the risk of uranium disuse even with carrying out proper uranium control and protection. However this effect is observed only when there are large opportunities to search for insiders (the search area is comparable to the existing set of nuclear facilities). The obtained results also prove that a reduction in the level of NM safe management at facilities could allow the collector to complete a chain of unauthorized actions with a significant probability (PSQ>0.1).
- ПубликацияТолько метаданныеSimulation of Crude Chloroform Purification Methods(2019) Naletov, V. A.; Glebov, M. B.; Naletov, A. Y.; Khitrov, N. V.; Glebov, V. B.; Глебов, Василий Борисович© 2019, Springer Science+Business Media, LLC, part of Springer Nature. Crude chloroform purification methods to remove impurities with properties similar to those of chloroform (1,1-dichloroethane and cis-1,2-dichloroethylene) were analyzed. The considered methods for removing impurities from crude chloroform included reaction-rectification and separate processing in a reactor and a distillation column. The results of simulation of the above schemes are presented. Comparative analysis of the results taking into consideration economic viability showed that purification of crude chloroform by reaction-rectification shows great promise.
- ПубликацияТолько метаданныеThe knowledge preservation problem in the nuclear industry and the role of Web-based tools in its solution(2019) Geraskin, N. I.; Kulikov, E. G.; Glebov, V. B.; Гераскин, Николай Иванович; Куликов, Евгений Геннадьевич; Глебов, Василий Борисович© The Author(s) 2019.This case study analyses an application of distance training in the practice of nuclear knowledge preservation. The purpose of the research is to evaluate the potential of distance training in solving the problem of knowledge preservation in the nuclear industry. Thirty specialists from different European countries participated in the pilot training experiments. It was found that the efficacy of distance training depends directly on the convenience and ease of the knowledge transmission process, the possibility for the trainees to combine training with their professional activities, the ability to work independently and a conscious desire on the part of trainees to improve their professional competencies. The study included a comprehensive evaluation of the distance training platform Cyber Learning Platform for Network Education and Training (CLP4NET) in the context of nuclear knowledge preservation. It was found that CLP4NET provided a friendly interface, was relatively easy to use and allowed an extensive application of interactive data representation forms and ample communication between training participants.
- ПубликацияТолько метаданныеImplementing energy-efficient autonomous power systems with trigeneration for increasing the profitability of oil production(2019) Naletov, V. A.; Glebov, M. B.; Naletov, A. Y.; Glebov, V. B.; Глебов, Василий Борисович© 2019, Neftyanoe Khozyaistvo. All rights reserved. Heavy oil production is characterized by low profitability and low oil recovery factor value. This is due to the necessity of using external power sources for the production process, on one hand, and on the other hand – due to the limited number of possibilities for using cheap resources in implementing efficient enhanced oil recovery methods. These problems can be successfully solved by utilizing energy-efficient multifunctional power systems. The design of suitable power equipment for cost-effective heavy oil production must be based on ener-gy-saving and, preferably, energy-autonomous power systems. In this regard, for high-viscosity oil fields with low gas-solubility factor values and increased power consumption per unit of oil produced the technology of power generation from associated petroleum gas becomes economically attractive. Such systems present a combined solution to the problems defined and do not require external carbon dioxide sources. The autonomous trigeneration power can be adapted for the feedstocks available on-site (associated petroleum gas or the flue gases from nearby power plants if present), produce the heat and power necessary for heating the viscous oil and produce carbon dioxide to reduce oil viscosity and improve phase mobility. Implementing trigeneration power systems makes it economically viable to develop and apply thermal and gas injection methods for improving oil recovery. The power systems comprise, as a rule, a power module that uses the associated petroleum gas produced on-site, a carbon dioxide capture module and a compression module for obtaining liquid or supercritical carbon dioxide. The structure of the autonomous trigeneration power system and the methodology of its implementation for oil production are presented. A comparison of the proposed autonomous power system with analogous overseas solutions is given.
