The purpose of this study is to measure the quality of nuclear science and technology research using the scientometric indicators, like activity index, attractivity index and publication efficiency index.

The present scientometric study is based on the bibliographic data extracted from the core collection of the Web of Science database from 1989 to 2019. The data was collected using the advanced search feature, with a search string of 28 related terms. The bibliographic data for all the journal articles, excluding all other formats, was downloaded for statistical analysis.

The present study highlights the growth pattern and the research efforts devoted to the field of nuclear science and technology worldwide, as reflected through the Core Collection of the Web of Science database, for 31 years from 1989 to 2019. The USA has emerged as the topmost producer, with a total share of almost 29% with respect to the world literature followed by Japan, Germany, France and UK. However, the relative citation impact has been the highest for Netherlands followed by the USA, Germany, France and UK, respectively. The study depicted that the activity index, also called as the relative performance indicator, has been the highest for the USA, whereas the attractivity index has been the highest for China, indicating its dominance in attracting citations to its publications in the field of nuclear science and technology. The publication efficiency index, the value has been the maximum for Iran, for which the value has been greater than 1 (1.618). The measure suggests that Iran’s research effectiveness in the field of nuclear science and technology has been more than the research effort devoted to the field.

The paper was based on the data retrieved from a single database, and the results may vary across other databases. Hence, caution should be taken while generalizing the findings.

Several scientometric studies have taken place in the field of nuclear science and technology, particularly in its allied branches, but none of the studies has focused on evaluating the research efforts carried out by the countries in terms of activity index, attractivity index and publication efficiency index, and the present study is an attempt to fill the gap.

The purpose of this paper is to make an assessment of the global status of research in nuclear science and technology (NST) publications.

The present bibliometric study is based on bibliographic data that were retrieved from the Web of Science during 2001-2010. In all, 85,198 records published by the 35 journals under the category of NST in the database of Journal Citation Reports were assessed in terms of many aspects. A further assessment has been made using advanced bibliometric indicators such as field citation scores and collaboration network analysis using the NetDraw software.

Unlike research-prolific countries, the annual growth rates of publications for most developing countries have experienced an evident leap. The highest scientific impact and productivity among the publications belonged to the International Journal of Radiation Biology (10.46). A limited group of prolific authors produced a considerable portion of the publications, among whom, Japanese authors had the most contributions. The USA is in the centre of the international collaborative network illustration and is also the main partner of most of the research-prolific countries. Nuclear physics has the greatest field normalised measured impact ratios (CPP/FCSm = 4.2) among the publications, which signifies its inherent impact on NST research. In general, like the inter-institutional collaborative publications, the internationally collaborative publications are more frequently cited and therefore have a higher scientific impact.

The paper could aid to show collaborative research in the NST journals and assess the research performance of the NST.

The aim of this study is to examine the significant factors to improve the green nuclear energy investments in the emerging economies. For this purpose, balanced scorecard-based criteria are weighted with DEMATEL methodology. The findings demonstrate that technological improvement and financial issues are the most important issues for the improvement of the green nuclear energy investments in these countries. Nuclear energy working with thorium can also be obtained with proton accelerator technology that is currently quite expensive. Because of this problem, the investors are not willing to make investments for green nuclear energy projects. Hence, emerging countries should make the necessary technological investments to have proton accelerator technologies. With the help of this condition, it will be possible to reduce the cost of green nuclear energy projects which attracts the attention of the investors. This situation has a powerful contribution for the sustainable economic development of these countries.

The decentralised information strategy upon which the International Nuclear Information System (INIS) was established has stood the test of time. INIS celebrated its 25th anniversary during 1995. One of the world's early international computerised systems, INIS was born in 1970 with its mission to produce and disseminate a database containing records of the world's literature on the peaceful applications of nuclear science and technology, and full text of non‐conventional (grey) literature. Since that time, the INIS Database has grown to over 1.8 million bibliographic records and abstracts. It continues to increase by approximately 85 000 records each year. Additionally, INIS generates full‐text microfiche of approximately 20 000 non‐conventional literature documents each year as well as a number of other information products and services. As of 1976, INIS could be considered the world's most comprehensive abstracting and indexing service in the field of atomic energy. Ninety‐four Member States (countries) and 17 cooperating international organisations currently participate in INIS. A decentralised operational philosophy is at the core of the information strategies of the organisation. INIS is, in effect, an international information cooperative made up of members who are the contributors as well as the benefactors of the system. Participants get a return on their information investment: member countries who publish and therefore contribute a few records have access to the collective 85 000 records submitted annually by all members, as well as to the full database. One of the major advantages of decentralisation is that it tends to stimulate the establishment and improvement of an international information infrastructure, as well as the transfer of modern information technology. Systems such as INIS, which capitalise on information technology transfer, information skills development and the use of standards for information management and exchange, have contributed to paving the way for the global information highway envisioned today. The INIS decentralised global information management strategy has stood the test of time and will be critical in the future information industry. INIS will embrace the changes necessary to remain in the forefront of the information society.

The computerized information centre of the European Atomic Energy Community has become operational. A survey of its principal characteristics is given, and the main problems that arose in the development phase of the system are discussed. The Euratom Thesaurus includes graphic representation of relationships between indexing terms. A dual vocabulary allows specific indexing for high relevance and generic indexing for high recall. Retrieval strategy involves utilization of Boolean operators and frequency‐of‐occurrence tables. Recall ratio can be determined graphically by a continuous approach method. Indexing consistency tests show that it pays to use subject specialists. Users' needs are discussed in terms of subject coverage, specificity, rapidity, and presentation. The user service comprises retrospective searches on request as well as a customer profile service on subscription. There are three types of relevance, and various ways of bringing system relevance to coincide with user relevance. The Centre's budgetary requirements are low, due to circumspect use of its computer, an IBM 360, model 40. Its aims are centralization of documentation in the nuclear field and international co‐operation.

The purposes of a subject index in a small information service are examined and the organizational aspects of the Big information Centre and the Small Service in relation to the descriptor level are analyzed. The advantages of co‐ordinate indexing versus the conventional hierarchical classification in meeting complex information needs are pointed out. Through an evaluation of the flexible structure of the thesauri, the lower‐level but otherwise similar vocabulary needs of the small service are discussed. The use of the UDC to effect the level transitions required to adapt the thesauri to the needs of the Small Service is examined. It is shown how an improved subject index for the Soreq book collection has been constructed by the combined use of the EURATOM Thesaurus and the UDC. Examples to illustrate the design of this index are given. In the interest of expanding the co‐operation between the small Service and big centre, the idea of a multi‐level thesaurus is proposed.

Many literature reviews on project management (PM) research are limited to studies published only in PM journals but some reviews do expand their analysis on PM research published also in journals belonging to the management studies field. However, the authors found no previous literature reviews comparing the PM content in different sectors outside the management studies field. Therefore, the analysis and findings of PM content derived from the sector-specific engineering and technology-focused journals are new. The paper aims to discuss this issue.

The authors analyze PM content in nine different sectors, where each sector and its inherent research is connected to specific engineering, technological, or industry-related disciplines. The authors conduct an evidence-informed literature review on PM knowledge in the distinct literatures of these nine sectors. The period of analysis is 24 years from 1986-2009. The authors discuss potential consequences of the findings’ sector-specificity for future PM domain development.

The perspective on different origins of PM leads to a meta-level PM concept covering several different PM domains, each with its own sector specific and separated development path.

The literature analysis purposefully excluded PM journals and management studies, and the authors focused only on sector-specific engineering and technology-focused journals that represent knowledge and wisdom of different PM contents in nine sectors.

The findings have significant potential to contribute to scholarly discussion on the development of a universal PM theory. For applicability across sectors, the authors suggest a modular PM theory with different sector-specific modules for knowledge, concepts, and underlying assumptions.

Currently, this discussion has been mainly focused on theorizing concepts and approaches in management studies only. This study expands the understanding to engineering and technology-focused journals across nine industry sectors/domains.

The relatively low capital cost and contributions to mitigating global warming have favoured the continuous construction and operation of nuclear power plants (NPPs) across the world. One critical phase in the operation of nuclear plants for ensuring the safety and security of radioactive products and by-products is decommissioning. With the advent of digital twinning in the building information modelling (BIM) methodology, efficiency and safety can be improved from context-focus access to regulations pertaining to demolition of structures and the cleaning-up of radioactivity inherent in nuclear stations. The purpose of this study, therefore, is to propose a BIM-driven framework to achieve a more regulation-aware and safer decommissioning of nuclear power plants.

The framework considers task requirements, and landscape and environmental factors in modelling demolition scenarios that characterise decommissioning processes. The framework integrates decommissioning rules/regulations in a BIM linked non-structured query system to model items and decommissioning tasks, which are implemented based on context-focussed retrieval of decommissioning rules and regulations. The concept’s efficacy is demonstrated using example cases of digitalised NPPs.

This approach contributes to enhancing improvements in nuclear plant decommissioning with potential for appropriate activity sequencing, risk reduction and ensuring safety.

A BIM-driven framework hinged on querying non-structured databases to provide context-focussed access to nuclear rules and regulations and to aiding decommissioning is new.

To present dynamical analysis of axisymmetric and three‐dimensional (3D) simulations of a nuclear fluidized bed reactor. Also to determine the root cause of reactor power fluctuations.

We have used a coupled neutron radiation (in full phase space) and high resolution multiphase gas‐solid Eulerian‐Eulerian model.

The reactor can take over 5 min after start up to establish a quasi‐steady‐state and the mechanism for the long term oscillations of power have been established as a heat loss/generation mechanism. There is a clear need to parameterize the temperature of the reactor and, therefore, its power output for a given fissile mass or reactivity. The fission‐power fluctuates by an order of magnitude with a frequency of 0.5‐2 Hz. However, the thermal power output from gases is fairly steady.

The applications demonstrate that a simple surrogate of a complex model of a nuclear fluidised bed can have a predictive ability and has similar statistics to the more complex model.

This work can be used to analyze chaotic systems and also how the power is sensitive to fluctuations in key regions of the reactor.

The work presents the first 3D model of a nuclear fluidised bed reactor and demonstrates the value of numerical methods for modelling new and existing nuclear reactors.
