The design, construction, and operation of a nuclear power plant (NPP) pose technological and R&D challenges for the organisations concerned. The purpose of this paper is to analyse the sources of innovation and the technological developments throughout the construction and commissioning processes for Atucha II NPP.

Studying a high-risk organisation that is reliable in practice poses several research questions the authors consider in this work. What kind of R&D processes can take place in a mature industry like the nuclear sector in Argentina? How have technological challenges been overcome since the restart of the completion phase of Atucha II NPP? Primary data were mostly gathered through semi-structured interviews. Grounded theory was the methodological approach adopted.

Multiple sources of technological developments arise, an incremental R&D pattern being the most salient. Atucha II NPP seems to be a case of network innovation in a triple helix innovation scheme led by the Argentinian state. In effect, one of the outcomes of the construction of the Atucha II NPP was the development of the Argentinian nuclear sector together with the development of organisational capabilities. In this sense, the third Argentine NPP follows the socio-technical path of the Argentine nuclear industry.

Too little is known about R&D processes in high reliability organisations (HROs), especially in the nuclear sector of a Latin American country such as Argentina as there seem to be no organisational studies analysing HROs’ impact on innovation, reliability, and economic development.

Diseñar, construir y operar una central nucleoeléctrica plantea desafíos tecnológicos y de innovación a las organizaciones involucradas. Este artículo analiza las fuentes de innovación y los desarrollos tecnológicos del proceso de construcción y puesta en marcha de la central nucleoeléctrica Atucha II.

Abordar el estudio de una organización concebida desde la teoría como altamente riesgosa pero confiable en la práctica plantea múltiples interrogantes. ¿Qué tipo de procesos de I+D se pueden dar en una industria madura como la nuclear civil, en Argentina? ¿Cómo se afrontaron los desafíos tecnológicos a partir de la reactivación de un proyecto abandonado durante más de una década? La entrevista semi-estructurada a interlocutores clave fue el instrumento de intervención predominantemente utilizado. Se adoptó el enfoque metodológico de la teoría fundada.

Del análisis del caso surgen diversas fuentes de desarrollos tecnológicos prevaleciendo un patrón de I+D incremental. Se trata de un caso de innovación en red en el marco de un modelo de triple hélice liderado por el Estado. En efecto, una de las resultantes de la construcción de Atucha II es el desarrollo del entramado del sector nuclear argentino junto con el desarrollo de capacidades organizacionales. En ese sentido, la tercera central nuclear de potencia argentina retoma la trayectoria socio-técnica del sector nuclear argentino.

Resultan escasos los conocimientos sobre los procesos de I+D en organizaciones de alta confiabilidad (HROs), especialmente del sector nuclear de un país latinoamericano como Argentina así como se carece de estudios organizacionales que analicen el impacto de las HROs en la innovación, la confiabilidad y el desarrollo económico.

This paper aims to investigate the major causes of the nuclear power plant (NPP) disasters since 1950, elucidates the commonalities between them and recommends strategies to minimize the risk of NPP disasters.

This paper analyzes facts from five case studies: Chernobyl disaster, USSR 1986; Fukushima Daiichi disaster, Japan 2011; Three Mile Island incident, USA 1979; Chalk River Accident, Canada 1952; and SL-1 Accident, USA 1961. A qualitative approach is adopted to compare and contrast the major reasons that led to the accidents, and consequent social and technological impacts of the disasters on environment, society, economy and nuclear industry are analyzed.

Although each of the nuclear accidents is unique in terms of its occurrence and impacts, this research study found some common causes behind the accidents. Faulty system design, equipment failure, inadequate safety and warning systems, violation of safety regulations, lack of training of the nuclear operators and ignorance from the operators and regulators side were found to be the major common causes behind the accidents.

This paper recommends some of the nuclear disaster risk reduction strategies in terms of “lessons learned from the past accidents”. The findings of the research paper would serve as an information tool for the nuclear professionals for informed decision-making and planning for proper preventive measures well in advance so that the mistakes which led to the occurrence of accidents in the past are not repeated in the future.

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.

This paper aims to critically evaluate the impact of empowering leadership on safety behavior and safety climate during safety monitoring at a nuclear power plant (NPP) in the United Arab Emirates (UAE).

Data were collected using questionnaires filled out by 500 participants from the UAE nuclear sector. The relationships among the variables were analyzed using structural equation modeling.

The results indicated that empowering leadership has a positive impact on safety behavior, and a positive safety climate leads to increased levels of safety behavior (compliance and participation). The results also showed that safety climate partially mediates the relationship between empowering leadership and safety behavior.

This study contributes to the existing knowledge regarding empowering leadership, safety monitoring, behavior and climate. Because limited information is available on this topic, this study extends the research on the relationship between empowering leadership and safety research at an NPP. Specifically, it outlines that safety monitoring partially mediates the relationship between empowering leadership and safety behavior. This research enables NPPs worldwide to incorporate empowering leadership to enhance safety monitoring and ensure better safety behavior and climate.

With the increase in population, the energy needs of countries are also increasing. These countries have difficulties in meeting these increasing needs. Countries that cannot meet this need have to import energy from abroad. This situation adversely affects the current account balance of countries. Nuclear energy investments allow countries to obtain their own energy, although there are some criticisms. In this framework, while some countries in the world increase their nuclear energy investments, some countries do not have any nuclear power plants (NPP). There are 32 such countries where nuclear energy projects are running till date. Therefore, it is very important to determine the socio-economic variables of countries that have nuclear energy investments. In this context, a detailed literature analysis will be made first to determine socio-economic criteria. Then, the importance weights of these factors will be calculated using the Decision Making Trial and Evaluation Laboratory (DEMATEL) method. The profiles of the countries that make nuclear energy investments demonstrate that education level is the most essential socio-economic factor for the improvement of nuclear energy investments. Also, income inequality is another important variable in this regard. However, consumption behaviour and saving behaviour have the lowest weights.
