Ukraine’s nuclear security as a key element of the European security system

Abstract

Ukraine, as a strategically located territory and an important player in the geopolitical interests of various power blocks, has become a key element of the European nuclear security system, so it is important to study the most important factors shaping the situation around nuclear weapons and take appropriate measures to avoid potential threats. The research aims to outline all aspects and factors of Ukraine’s nuclear security that directly affect the international security system, in particular, the European countries. The methodological basis of the study is a systematic analysis of information and regulatory sources, such as bilateral and multilateral international agreements, documents and materials of international organisations, documents of individual country authorities, speeches, and materials of print and electronic media. The article highlights the historical context, including the transfer of Ukrainian nuclear weapons materials to Russia following the Treaty on the Non-Proliferation of nuclear weapons. The current stage of development of the international nuclear non-proliferation regime is analysed. Attention is paid to the evolution of the regime under the influence of the confrontation between the two superpowers and the doctrine of mutual deterrence. The situation with nuclear security in Ukraine and its impact on the Black Sea region is analysed. The consequences of military actions in Ukraine and factors that create new dimensions for nuclear security, in particular in the context of control over nuclear materials and the possibilities of their use, are considered. The results of the study of the problem are presented in the description of new threats and risks that require deepening cooperation of international partners and taking effective measures to ensure nuclear safety in the region. The study emphasises the need for joint efforts to counter new challenges and minimise nuclear safety risks. The practical significance of the study is determined by strategies for cooperation with international partners to achieve stability in the field of nuclear safety
