“…While previous studies have made efforts to identify and rank various risks associated with nuclear decommissioning projects [9][10][11][12], there remains a notable gap in the literature concerning the systematic prioritization of these risks to aid decision-making regarding both structural aspects and worker safety. The absence of a systematic approach to risk assessment in prior research raises significant concerns regarding the effectiveness and comprehensiveness of risk management strategies in nuclear decommissioning pro-jects.…”

“…In this regard, previous studies have attempted to identify and rank many risks including waste management, safety, radiological, etc. [9][10][11][12] However, there has not been an extensive study that systematically ranks (prioritizes) the elements of risks to assist in making decisions regarding both the structural aspects and the safety of workers involved. Previous research by [13] emphasized the importance of systematic risk assessment in nuclear decommissioning projects, highlighting that such projects involve numerous hazards and complexities that must be carefully managed.…”

Over 50% of nuclear power plants (NPPs) worldwide have operated for over three decades, leading to a surge in decommissioning projects. This study addresses the gap in current guidelines by analyzing risks in nuclear decommissioning. Using the fuzzy-AHP technique, tasks within dismantling radioactive concrete structures are prioritized. Findings reveal structural and human-related risks across five main cutting tasks. Collision emerges as a significant concern, particularly during wire saw installation and concrete block hoisting hole creation. Subcategory risk priorities highlight variations in risk across tasks, with jamming, falling, and falling objects identified as top concerns during wire saw transportation. This study emphasizes the importance of comprehensive risk assessment in enhancing safety during decommissioning. It underscores the need to consider both physical risks and risks to personnel throughout the process. By prioritizing safety, stakeholders can ensure worker safety and operational efficiency while minimizing hazards. This research contributes to standardized safety protocols for nuclear decommissioning worldwide, aligning with sustainable energy practices. The outcomes offer practical insights for safety manual development and decision-making processes. This study represents progress in ensuring safety during nuclear decommissioning, paving the way for further refinement of safety protocols and guidelines tailored to decommissioning sites.

“…Nuclear power plants are far safer than is often believed, and they are the only kind of power plant that can generate electrical energy nonstop for the whole 365 days and 24 hours of each year, regardless of the weather or any other external factors (Vitázková & Cazzoli, 2013). Obviously, in addition to all these occurrences, the effects of nuclear catastrophes are also quite significant and eye-catching in their scope and magnitude.…”

The fast growth of digital technologies is causing a lot of trouble in the logistics industry, which is causing the industry to change in a big way. The idea of "lights-out logistics," which refers to the automation of logistics operations through the use of digital technologies such as robotics, autonomous vehicles, and artificial intelligence, is one of the most significant shifts that has taken place. In this chapter, a summary of the lights-out logistics concept is presented, along with a discussion of its advantages, challenges, and potential effects on the logistics industry. Aside from that, the chapter focuses on the critical technologies and applications that enable lights-out logistics, as well as the strategies and best practices that businesses can use to successfully implement this concept. This chapter uses different case studies and examples to show how lights-out logistics can help businesses improve their operational efficiency, lower their costs, and improve the customer experience. A discussion of the future prospects of lights-out logistics and its potential to transform the logistics industry in the digital age serves as the chapter's conclusion.

The principle of Defence-in-Depth in the perspective of Probabilistic Safety Analyses in the wake of Fukushima

The principle of the Defence-in-Depth concept has been set forth by the IAEA as fundamental for the safety of Nuclear Power Plants in INSAG10 (1996). Within the time, essentially after severe accidents in Three Mile Island and Chernobyl, the concept evolved and the currently accepted definition is based on five successive layers of safety and four physical safety barriers, including organizational and administrative measures. Safety demonstrations are required to show that the safety layers and barriers provide sufficient margin to prevention or mitigation of releases of radioactivity to the environment. These safety demonstrations are well established for Design Basis Accidents. Probabilistic Safety Assessments (PSAs) assumed to be risks assessment tools also for Severe Accidents, however, enter the description of the Defence-inDepth concept only as an afterthought and their role is marginalized to "improvement of defence in depth" and "optimization of efforts to implement defence in depth". This article investigates aspects related to implementation of defence in depth in the wake of the Fukushima accidents and in view of the historical evidence of nuclear power plants' risks considering also risk targets complying with IAEA safety objectives and principles. Analysis of the levels of currently accepted defence in depth is performed focusing on real accidents vs. PSA analyses results with objective to answer the question, if some of current defence-in-depth levels may not actually be yet a reason of concern instead of prevention or mitigation of risk, and, what should be the role of risk targets and risk assessment within the defence in depth concept.
