Nuclear security and nuclear safety: Definition, legal aspects and holistic approach to the concepts

Abstract

The subject of this paper is scientific description of the terms nuclear security and nuclear safety, with reference to international legal aspects and necessary holistic approach to these concepts. Taking into account that there are overlapping and inconsistent use of the abovementioned terms in both domestic and foreign literature, the aim of this paper is to describe them precisely, point to the main differences and similarities in terminology, in order to enable their understanding, adequate use in scientific and professional literature, as well as holistic approach in practice. The connection between the terms stems from their common goal - protection of people and the environment from harmful influence of radioactivity, whereas the terms diverge in areas where the requirements for achieving nuclear security and nuclear safety are in complete contradiction. Nuclear security refers to the protection of nuclear materials and facilities from unauthorized access, theft and abuse, with primary focus being on preventing criminal activities. Nuclear safety, on the other hand, has an aim to prevent accidents in nuclear facilities, as well as to protect people and the environment from potentially harmful influence of radioactivity. Holistic approach requires integration of nuclear security and safety measures, in order to achieve synergy between the two concepts, and, at the same time, make sure that their implementation does not jeopardize one another. This way, societies and states can reduce risks to nuclear materials and facilities, both from unauthorized access and potential hazards arising from nuclear processes and facilities.
