Information and Communication Technologies and Internet networks are present in all aspects of social reality and are essential elements in research, development and innovation centers (R&D&I). Cyber-security is crucial for the progress of the research activities developed in these centers, especially given the exponential growth of cyber-attacks and incidents. The present study aims to assess from a socio-technical approach, how a serious cyber-attack on a Spanish research center has affected staff’s perceptions of information and communication systems (ICT) security. This study employed a mixed-methods research strategy, combining quantitative and qualitative methods to provide a comprehensive and nuanced understanding of ICT security perceptions among employees. First a quantitative scale was administered to 1,321 employees 3 years before the cyber-attack and 4 months afterward, to measure ICT security perceptions. Then, qualitative techniques (semi-structured interviews, focus groups, and micro-ethnography) were applied to gain a deeper understanding of the arguments underpinning cyber-security at the center after the attack. The results show that the event had an impact on employees’ perceptions, increasing the perceived importance of ICT security, with positive behavioral changes noted, but with doubts about their sustainability over time. Also, the need for cyber-security governance was critically contrasted with organizational reality. Finally, the compatibility of science and cyber-security was a central dilemma, which seems to confront antagonistic poles (research and security ICT) and justify the non-compliance with security protocols by part of the staff.

Safety culture is the result of values, attitudes, and perceptions of the members of an organization that prioritize safety over competing goals. Previous research has shown the impact that organizational aspects can have in safety performance. Under the prism of the theoretical approaches from the high reliability organizations theory (HROT), resilience engineering (RE), and conflicting objectives perspective, this study was aimed at describing the overall main safety culture traits of the Spanish nuclear power plants, as well as identifying particularities associated with subcultures. For this purpose, a statistical analysis of safety culture surveys and behavioral anchored rating scales (BARS), handed over to all the operating Spanish nuclear power plants, was carried out. Results reveal that safety is a recognized value that prevails over production, there is a high degree of standardization, power plants are better prepared to organize plans and strategies than to adapt and cope with the needs of a crisis, and there is a critical and fragmented perception about the processes of resources allocation. Findings also identify that sociodemographic aspects, such as work location and contractual relationship, seem to be shaping differentiated visions. Several safety implications linked to the results are discussed.

Renewable hydrogen is emerging as the key to a sustainable energy transition with multiple applications and uses. In the field of transport, in addition to fuel cell vehicles, it is necessary to develop an extensive network of hydrogen refueling stations (hereafter HRSs). The characteristics and properties of hydrogen make ensuring the safe operation of these facilities a crucial element for their successful deployment and implementation. This paper shows the outcomes of an analysis of hydrogen incidents and accidents considering their potential application to HRSs. For this purpose, the HIAD 2.0 was reviewed and a total of 224 events that could be repeated in any of the major industrial processes related to hydrogen refueling stations were analyzed. This analysis was carried out using a mixed methodology of quantitative and qualitative techniques, considering the following hydrogen value chain: production, storage, delivery and industrial use. The results provide general information segmented by event frequency, damage classes and failure typology. The analysis shows the main processes of the value chain allow the identification of key aspects for the safety management of refueling facilities.

Organizational culture determines the norms, values and behaviors of an organization, playing a key role in the safety of high-reliability organizations (HRO). Previous research has shown that differentiated subcultures can coexist within organizations, sharing some norms and values but not necessary everything From this perspective, this study was aimed at (1) describing the organizational culture of the Spanish nuclear industry and (2) determining the potential presence of organizational subcultures. To do that, a statistical analysis of organizational culture surveys (Organizational Culture Inventory®, N = 5825) handed over to all organizations within the Spanish nuclear industry, was carried out. Results allow us to accurately characterize the industry’s organizational culture, which is made up of predominant “Constructive”-style behaviors together with “Defensive” normative patterns of the “Conventional”, “Dependent” and “Perfectionistic” styles. Indications about the existence of various subcultures associated to the nuclear organization type, the sociodemographic aspect and the organizational structure component were also found. Certain safety implications potentially linked to the existence of subcultures and to the industry’s organizational culture are discussed.
