The key aspect of radiation-proof manipulators used in nuclear industry is human presence in the manipulator control loop due to a wide variety of performed operations and the nondeterministic nature of the working environment. Relatively large distances between the control stations and the manipulators, imperfect visibility of the sealed chamber’s inner space from the control station necessitate the use of computer vision systems. They serve both for general chamber observation as well as local observation of the manipulator end-effector working area. High levels of radiation impose certain limitations on the primary video sensors with regard to radiation resistance and service life. This requires special technical solutions to ensure additional radiation protection as well as design and algorithmic ways of minimizing the influence of hazardous environment. Modern trends in digital manufacturing design are based on a system of unique identification of materials, package, etc. One of the technically viable ways is applying optical labels containing barcodes that are identified by algorithms. The article covers the design, structure, functional possibilities and experimental results of one of the radiation-proof manipulator vision systems. This system is designed for working together with radiation-proof robotic electromechanical manipulators installed in sealed chambers of nuclear plants.

Diagnosis Errors

Advancements in the nuclear industry have led to the development of fully digitized main control rooms (MCRs)—often termed advanced MCRs—for newly built nuclear power plants (NPPs). Diagnosis is a major part of the cognitive activity in NPP MCRs. Advanced MCRs are expected to improve the working environment and reduce human error, especially during the diagnosis of unexpected scenarios. However, with the introduction of new types of tasks and errors by digital MCRs, a new method to analyze the diagnosis errors in these new types of MCRs is required. Task analysis for operator diagnosis in an advanced MCR based on emergency operation was performed to determine the error modes. The cause-based decision tree (CBDT) method—originally developed for analog control rooms—was then revised to a modified CBDT (MCBDT) based on the error mode categorizations. This work examines the possible adoption of the MCBDT method for the evaluation of diagnosis errors in advanced MCRs. We have also provided examples of the application of the proposed method to some common human failure events in emergency operations. The results show that with some modifications of the CBDT method, the human reliability in advanced MCRs can be reasonably estimated.

Human Emotions

In order for humans and robots to interact in an effective and instinctive manner, robots must obtain information about the human emotional state in response to the robots actions. This is important as the presence of robot in manufacturing industry is very wide and robot plays a big role in the emerging of automation manufacturing technology. Consequently, we believed that it is necessary to investigate how human feel about this situation and if robot can understand those human emotions, collaboration with human can be much better. In order to investigate the human emotions, we applied akanseisurvey method based on akanseiengineering technology. We request a number of participants to take part in our experiment where they will be in the same environment of where a robot is working on some tasks. The participants will answer those questions in the survey based on what they feel about working together with moving robot. The overall goal is, in fact, to predict in which area in the vicinity of the robot that the human is heading to, especially in term of humans feeling, so that by understanding how human feels of working together with robots, perhaps we can create a better working environment. This paper describes the results of our findings about how human feel when collaborating with robot (s).

The Middle Cumberland Archaeological Project is a multi-institution research effort launched in 2010 that includes archaeologists with Florida State University, the Tennessee Division of Archaeology, and Middle Tennessee State University, working together to identify and assess Archaic shell-bearing sites in the western Middle Cumberland River Valley of Tennessee. In 2012, the project investigated the substantial Archaic shell-bearing deposits at archaeological site 40DV7, located on the Cumberland River in Davidson County, Tennessee. This interdisciplinary project gathered basic site-level data regarding the horizontal and vertical extent of cultural deposits, radiocarbon assays to determine site chronology, bulk and column samples for flotation and water-screening to aid in zooarchaeological analysis and paleoethnobotanical analysis, and geomorphological samples of the immediate environment. The results of the 2012 excavations, combined with earlier data collected by the senior authors, provide significant new data about the occupation history and freshwater shellfish composition of this site. In addition, radiocarbon data presented in this chapter reveal that 40DV7 manifests the longest continuous Archaic shell-bearing occupation yet identified in the region, spanning the period ca. 6500–4500 cal BP.

China’s nuclear energy ambitions, backed by the strong financial potential of the national economy, and the consequent desire to extend its successes in international economic cooperation to the nuclear industry have attracted the researchers’ attention to a closer examination of the current state and nuclear industry prospects of China, taking into account its technological component. The unfulfilled development plan for nuclear power in the 13th Five-Year Plan, as a result of systemic mistakes and failures in the projects selected for implementation, leads to the conclusion that it is necessary to involve foreign leaders in this field, including “Rosatom” corporation, which has in its portfolio virtually verified modern technical solutions.

The Best Value (BV) environment was introduced into the Netherlands in 2006. By 2008 testing was being done by a partnership of Arizona State University and Scenter (Sicco Santema, professor from Delft University). In 2010, the first significant test of the BV approach was done by the Rijkswaterstaat to deliver the $1B fast track infrastructure projects, and by 2015, the BV approach had become the “buzzword” of procurement and the professional procurement organization NEVI. However, in the delivery of professional engineering services, larger, more traditional services which were built on a system of relationships between clients and vendors, clients controlling the expert, and the importance of “billable man-hours”. The transition from a traditional approach to a BV approach is very challenging. Large traditional professional organizations naturally will have more difficulty adapting to the new approach. The BV approach utilized the expertise of experts to replace the need for relationships and owner management, direction and control (MDC). It also places less value on traditional practices that have been used by professional services to get business (relationships and working together with the client in a trust based relationship). The study captures the efforts of a very successful engineering firm (the second largest in the Netherlands) as they attempt to become successful in this new approach. The Best Value team that they have put together has had outstanding results in using the BV approach to changing their paradigm.

There has been a steady growth of interest in the technology of small modular reactors (SMR) in the world recently. SMRs are considered as a promising area for the further development of nuclear industry. The paper defines the term “small modular reactor”, presents the scope, potential advantages and disadvantages of SMR. A review was made and a classification of SMR projects was proposed depending on the novelty of their technical solutions. The paper presents an enlarged comparative analysis of individual SMR technical solutions (based on the example of Holtec International SMR-160) with operating Ukrainian NPPs to identify peculiarities of SMR that should be addressed in licensing. Certain specific design solutions of SMR-160 are correlated with defense-in-depth levels. The approaches and condition for licensing SMR designs in the international practice are analyzed. The paper identifies problematic aspects with regard to regulatory framework and confirmation of the efficiency of SMR design solutions, as well as formulates proposals and recommendations for the first steps to ensure the licensing process in response to the initiative of the operating organization Energoatom.

The management of contaminated ground and groundwater is a notable contributor to dealing with the challenge we face in cleaning up the legacy of the UK’s civil nuclear industry in a safe, cost-effective and environmentally responsible manner. To facilitate this mission, the Nuclear Decommissioning Authority, Environmental Regulators and Safety Regulators are working together to develop common expectations for the management of contaminated ground and groundwater arising on and extending off nuclear licensed sites in the UK. The aims of this work are to: • set out shared expectations for land quality management, explaining any differing expectations where consensus is difficult; • interpret expectations to ensure they are clear and implementable, facilitating planning of programmes and deliverables; • provide a framework for dialogue against which progress in land quality management can be mapped; • promote positive action to manage land quality in a proportionate and sustainable manner to achieve consistent standards; and • identify whether areas of the regulatory framework or NDA contractual requirements warrant review and propose improvements for consideration, as appropriate. This paper outlines the process currently ongoing to identify the best way of achieving these aims in a manner that avoids compromising the respective statutory obligations, duties and functions of each party.

Intensive Development

A brief overview of the development of warehouses, logistics and distribution centers in Germany and other foreign countries at the present stage is presented. Some general development trends associated with the implementation of the concept of the fourth industrial revolution are identified. The implementation of these requirements provides for deep digitalization and intellectualization of production processes, control systems and applied technologies. A key role in the new conditions belongs to the design of logistics facilities using modern modeling and virtual reality capabilities. The analysis of the latest projects of warehouses with varying degrees of automation up to automatic warehouses was carried out. Examples of projects are given and the features of the adopted technical solutions are noted. Recently, a number of new technologies and systems have been developed and implemented in warehouse logistics. Of particular interest are new technologies for picking orders in warehouses, because The requirements for this technology have changed significantly due to the intensive development of online electronic commerce. The number of orders is constantly growing, and the requirements for the duration of these operations are dictated downward. Robotization has recently taken an important place. Working in a pandemic with the requirements for the maximum possible reduction in the number of personnel has further increased the relevance and importance of using robots, in particular, collaborative ones, i.e. working together with the person. Considerable attention is paid to the use in industrial logistics of floor transport with vehicles that work without drivers.

New prefabricated lightweight structures made of solid wood with connections for joining and building metal screws for wood are proposed. Manufacture and assembly of basic elements-bars with a cross-section of 15x15 cm can be carried out in line conditions on the simplest woodworking equipment. The use of local tim-ber material has a number of advantages (ecological, economic and operational). The description of structures with manufacturing process, examples of buildings with vaulted and hipped roofing, connection arrangement, preparation of experimental samples with the use of new equipment of the National Research Moscow State University of Civil Engineering are given. The method of analysis with allowance for plastic deformations is under consideration. It provides additional economic advantages. The analysis is carried out by the method of integral estimates developed by Prof. V.M. Bondarenko for reinforced concrete structures and adapted to wooden structures by Prof. K.P. Pyatikrestovsky. Special strength criteria are used for the analysis of decks working together with the ribs (in a combined stressed state). It is planned to build buildings for various purposes in the ar-eas of development of the Far North of Russia.

How can students become transformational leaders if they are left alone to grapple with the emotional toll of climate change, preparing for careers while scientists sound the alarm that business as usual is untenable? Ecoanxiety, solastalgia, and climate grief are the affective undercurrents in sustainability and environmental science classrooms. This case study discusses strategies used to support students’ emotional well-being in an introductory sustainability class and a co-curricular climate change support group program at Oregon State University. Psychologists and sustainability educators created space for students and faculty to engage in authentic dialogues confronting the emotional uncertainty of the climate crisis and working together to define their roles building a resilient future.
