The article is an attempt to summarize the experience of coping with urban problems caused by major human-made disasters. Based on the analysis of archival materials and other sources, the authors reproduce the situation in particular in Kyiv after the accident at the 4th Unit of the Chornobyl Nuclear Power Plant in 1986. It is proved that the official claim that radioactive emissions from the destroyed reactor bypassed the city was false. Data on the actual situation of radioactive contamination of the territory of Kyiv was published in Kyiv newspapers only in the beginning of 1991. However, both the central and local authorities have made some efforts to overcome the harmful effects of the accident. Among its main activities are work on the study of pollution of the hydrosphere, elaboration of methods of water purification and practical steps to ensure its population in the contaminated territories; organization of active radiation control of food, agricultural products, markets, dairies, meat-packing plants, as well as the territory of the city, motor transport, etc .; improvement and improvement of the sanitary condition of the urban space, resolving the issue of bio-waste disposal, decontamination of wildlife objects, residential, public and technical premises. The city authorities have taken many steps to protect the population of Kyiv from the possible effects of radiation contamination - for example, trying to regulate outdoor recreation. However, the authors claim, when the radiation background in Kyiv began to rise, no special measures for the protection of children were taken, and only in the second half of May, some children were sent away from the city. Already during independent development of Ukraine, work was being done to streamline the status of children affected by the Chernobyl disaster and, accordingly, to provide them with certain privileges defined by the legislation. It is noted that similar processes took place in 2011 and the Japanese city of Fukushima. Authors conclude, that the incompleteness of the process of dealing with the consequences of accidents at nuclear power plants in Ukraine and Japan, the likelihood of recurrence of such events, make the long experience of Kyiv significant for the residents of Fukushima and the human community as a whole.

Este artigo propõe-se a ser uma colaboração com os estudos dedicados às irmandades religiosas brasileiras, na sua face regional. A linha de pensamento adotada toma a cidade, a experiência urbana e as ditas associações religiosas como instâncias sociais intimamente relacionadas e interdependentes. Durante o século XIX, a irmandade gestora da Santa Casa de Misericórdia em Porto Alegre cumpria um papel fundamental não apenas para a composição material de seu espaço, mas igualmente para conferir-lhe o status de importante cidade dentro do mosaico urbano que compunha o Império brasileiro. Tomando por base o histórico de ações concretas da irmandade, como a construção do Hospital, as iniciativas para a caridade e filantropia e a promoção das festas litúrgicas, este artigo analisa o vínculo indissociável entre o associativismo católico e o estilo de vida urbano dos setecentos e oitocentos. Palavras-chave: Irmandades Religiosas. Santa Casa de Misericórdia. Cultura Urbana.AbstractThis paper intends to collaborate with other works dedicated to the study of brazilian religious brotherhoods, in their regional aspect. The line of thought  adopted takes the city, the urban experience and the religious associations above mentioned as closely related and interdependent social instances. During the XIX century, the brotherhood in charge of the Holy House of Mercy in the city of Porto Alegre played a fundamental role, not just in the material composition of the urban space, but also in giving it the status of an important city within the urban mosaic comprised by the Brazilian Empire. Based on the (historic of) concrete actions of this brotherhood, as were the construction of the Hospital, the creation of a social representation for the notion of charity, and the promotion of liturgic feasts, this article analyses the unbreakable bond between catholic associativism and the urban lifestyle of the XVIII and XIX centuries.Keywords: Religious Brotherhoods.

The purpose of the article is an adaptation of the affective labor concept as a method for analyzing vandalism among young people. The article examines youth vandalism as a form of affective labor and identifies two types of effects. The first type deals with the experiences of the vandals themselves which cause the new subjectivity and collectivity; the second type refers to the effects experienced by the users of vandal-altered spaces: they begin to feel differently because the damage can seriously change the status, value, user qualities of the urban environment and the emotions it induces on inhabitants. The paper analyzes youth vandalism as a strategy which not only transforms the urban space visually (physically) but also consciously constructs the affects transforming the subjectivity of young people, social positions and community forms of both the vandals themselves and the users of the city. This approach, reflecting the strategic nature of the young people’s vandal activity, shows that vandal practice should be understood as the practice of space occupation, its appropriation, its de- and reconstruction and should be based on social topology and general ideas of actor-network theory. The socio-philosophical conclusions in the paper are illustrated by the results of interviews involving 17 participants from 7 youth communities conducted in summer and autumn 2017 in Yekaterinburg. The photographs of the damaged urban spaces in various city districts were also taken; the data were mapped, and the photo database was marked according to geographical location and types of damaged buildings. This helped to draw certain conclusions about the youth vandalism phenomenon. The article outlines the prospects for the use of the proposed methodology in the analysis of vandal damage and in urban vandalism prevention activities.

We present a cross-cutting review of three on-going Horizon 2020 projects (ADVISE, NOMAD, TEAM CABLES) and one already finished FP7 project (HARMONICS), which address the reliability of safety-relevant components and systems in nuclear power plants, with a scope ranging from the pressure vessel and primary loop to safety-critical software systems and electrical cables. The paper discusses scientific challenges faced in the beginning and achievements made throughout the projects, including the industrial impact and lessons learned. Two particular aspects highlighted concern the way the projects sought contact with end users, and the balance between industrial and academic partners. The paper concludes with an outlook on follow-up issues related to the long term operation of nuclear power plants.

When nuclear power plant (NPPs) is in fault, it may release radioactivity into the environment. Therefore, extremely high safety standards specification are required during its working. So it is critically important for fault detection and diagnosis (FDD). NPPs are composed of large and complex systems, it is of great significance to obtain the up-to-date information of NPPs’ running state. So FDD is used to provide the state of system accurately and timely in NPPs. Signed directed graph (SDG) can show the complex relationship between parameters and has advantages of conveniently modeling, flexible inference and so on, so SDG is adopted for FDD. To achieve SDG inference better, fuzzy theory is utilized for signal processing in the paper. Firstly, SDG model is built according to the basic steps and principles of SDG modeling, and the parameters are divided into three states which is monitored by fuzzy theory. Secondly, according to the status of parameters, SDG is used for FDD and to reveal the fault propagation path, thus possibility of each fault occurred is achieved. Finally, to verify the validity of the method, the simulation experiments are done for NPPs and the simulation experiments show that SDG-fuzzy theory framework for FDD can get the fault possibility and deeply explain the reasons of fault.

Abstract INCEFA-PLUS is a five year project supported by the European Commission HORIZON2020 programme. The project concludes in June 2020. 16 organisations from across Europe have combined forces to deliver new experimental data which is being used to develop improved guidelines for assessment of environmental fatigue damage to ensure safe operation of nuclear power plants. Within INCEFA-PLUS, the effects of mean strain and stress, hold time, strain amplitude and surface finish on fatigue endurance of austenitic stainless steels in light water reactor environments have been studied experimentally, these being issues of common interest to all participants. The data obtained has been collected and standardised in an online environmental fatigue database, implemented with the assistance of an INCEFA-PLUS led CEN workshop on this aspect. As the end of the project approaches, INCEFA-PLUS is developing and disseminating methods for including the new data into assessment approaches for environmental fatigue degradation. This paper provides an overall update to project developments since it was last presented at PVP2019 (PVP2019-93276), and provides provisional project conclusions (which will be finalised for presentation at the conference). As well as being a standalone paper, the paper will also serve as an introduction to other papers being submitted covering specific aspects of the project. In particular this paper summarises: • The results of 3 years of testing (nearly concluded at the time of paper submission) • A summary of revealed sensitivities to, and inter-dependencies between: ○ Mean strain and stress, surface finish, strain amplitude and hold time. ○ Environment ○ Material ○ Laboratory (including specimen size and form) • The latest thoughts on how the project results will be used to advance development of improved assessment guidelines. • Progress developing an International EAF database. • A summary of dissemination achieved and planned. • The status of INCEFA-SCALE plans for work after the end of INCEFA-PLUS.

This paper makes a brief introduction on AP1000 operation procedure system, including procedure classification, function and composition. In addition, key points of work flow process and the advantages of AP1000 operation procedures are described, among which the application of CPS (computerized procedure system) on AP1000 operation area and human factor engineering are highlighted. CPS, as an advanced procedure system, which is relatively new to existing nuclear power plants in China, does not only have the function of electronic indication for procedures, but also have the ability to monitor plant data, process the data and then present the status of the procedure steps to the reactor operator. Moreover, based on current situation, this paper offers several suggestions on procedure development for Sanmen AP1000 nuclear power project, i.e. first, we can ensure the quality of operation procedures by preparing a precise writer’s guideline, a friendly-interfaced procedure template, an efficient work configuration and an appropriate schedule; then determine the way how we are going to use operation procedures in English version; finally realize CPS Chinesization and localization gradually by digesting and absorbing API 000 technology from Westinghouse Electric Company. This paper gives an intact and systematic discourse on AP1000 operation procedure system and its characteristics. Besides, the latter part of this paper focuses on development of AP1000 operation procedures for Sanmen nuclear power plant and it would be a worthwhile reference for newly-built AP1000 units in China.

The article is devoted to the analysis of the industrial development dynamics in Cherepovets in the late imperial period, during the revolution, the establishment of Soviet power and the first Five-Year Plans of industrialization. The purpose of the study is to reconstruct Cherepovets industrialization in the context of the urban space development in the 1880–1940s before the construction of a metallurgical plant and gaining the status of an industrial center. In the 1880–1940s Cherepovets industry mainly served the needs of the city and the governorate. Small industries dominated in the city. They were located on the city outskirts, as well as near local rivers. The present research is based on materials taken from the archives of the Cherepovets Museum Association, the Cherepovets Documentation Storage Center, the Russian State Historical Archive, and from official state statistics and periodicals. The analysis of these documents allowed the author to study the dynamics of Cherepovets industry development. The article states that developmental peaks that were associated with a quantitative increase in factories and plants in the city and that occurred on the eve and in the first years of World War I, as well as in the second Five-Year Plan of Soviet industrialization. The decline in industrial production was influenced by political events related to the end of World War I, the revolution, the civil war, and the outbreak of the Great Patriotic War. They had a decisive influence on the economy of the country and the city. In the period under the study the urban space grew due to the expansion of urban outskirts, where industrial enterprises were built, and the inclusion of neighboring villages in the urban area. The results obtained in the study are significant for understanding the processes of the industrial potential formation in Soviet industrial centers, as well as for the subsequent studies devoted to the development of socioenvironmental urban problems caused by industrialization.

Tagging Methods

The electric utility industry uses equipment “tagging” methods to identify inoperable equipment and to prevent the status of equipment from being changed for various reasons. Tagging involves identifying such equipment with small tags or other indications and maintaining records of equipment status. Operator reliability in the proper placement of tags is a function of training, good tagging procedures, adequate equipment identification techniques and tag design, among other things. This paper presents the results of an investigation of the tagging process at nuclear power plants.

The U.S

As of January 2013, the U.S. Nuclear Regulatory Commission (NRC) has renewed the operating licenses of 73 nuclear units out of a total of 104 licensed units, allowing for up to 60 years of safe operation. In addition, the NRC has license renewal applications under review for 15 units and more than 13 additional units have announced plans to submit applications over the next few years [1]. This brings the total of renewed licenses and plans for renewal to over 97% of the 104 operating nuclear units in the U.S. This paper presents the status of the U.S. license renewal process and issues being raised for possible applications for subsequent renewals for up to 80 years of operation. By the end of 2013 there will be 26 nuclear plants in the U.S. (or 25% of the 104 units) that will be eligible to seek a second license renewal and by the end of 2016 this number will increase to about 50% of the 104 licensed units. Although some nuclear plant owners have announced plans to shutdown before reaching 60 years, the majority are keeping the option open for long term operation beyond 60 years. The factors that impact decisions for both the first license renewals and subsequent renewals for 80 years of safe operation are presented and discussed in this paper.

<p>The article presents an assessment of social development of Desnogorsk in comparison with other cities in Smolensk region. According to the research, Desnogorsk is a leader on a numbers of social development parameters. However, some parameters are lower than the average values. The social development of Desnogorsk is higher than that of the other cities in the region, but it has been declining since 1996 and now it is gradually approaching the average regional level. The main reason is the transfer of social responsibility from the city-forming enterprise to the city administration and the rapid population decline of the city. In the post-Soviet period there began an out-migration from Desnogorsk, mainly among young population. It is primarily caused by the monopropellant economy and the optimization of the industry. The socio-economic gap between the employees of nuclear power plants and other residents is gradually increasing. Desnogorsk displays the lowest level of labor mobility, if compared to other cities in the region. The low level of labor migration together with the migration outflow indicates a low adaptation of the population to economic and social changes.</p>
