| Summary/Abstract |
The article is devoted to problems of defining quantitative criteria for the physical protection system (PPS) effectiveness of nuclear facilities. The article briefly describes the scheme of the PPS development used in the nuclear industry in Russia, gives a review of existing approaches to defining the minimal acceptable value of the system's effectiveness, and reveals advantages and disadvantages of the approaches. The article describes in detail an approach based on facility categorization by potential losses and a technique of defining the minimal acceptable value of the PPS effectiveness developed on its base.

| Summary/Abstract |
Over the past two decades, the international community has devoted considerable attention to the human dimension of nuclear security. This trend is part of a more holistic approach to securing nuclear facilities, grounded in the concept of culture, that moves beyond the traditional focus of physical-protection measures. But what explains this shift and what does it entail? This article begins by demonstrating, through a series of real-life case studies, the potential for human factors to undermine nuclear-security systems. It then considers the rise and consolidation of “culture” as a concept used to better understand and organize international efforts to strengthen nuclear security. Nuclear-security culture is then explored in practice, drawing on a review of relevant initiatives as well as empirical research conducted by the authors at several UK nuclear sites. A number of likely challenges for developing an effective nuclear-security culture at the operational level are discussed, as is the value of the culture-focused guidance developed by the International Atomic Energy Agency. The article concludes that while nuclear-security culture has been widely promoted at the international level, there exists considerable scope for new initiatives to further strengthen engagement at the working level of industry.
