Cyber security of nuclear power plants in the context of International Law

In this study, the processes from the "Atom", which is the smallest building block of the material that was even mentioned by Aristotle, to the first uses of nuclear energy; from what the nuclear energy means in international law to the importance of nuclear energy compared to other energy sources and from humanitarian and military use to basic principles have been examined with a holistic approach. The use of nuclear energy in various areas, for what purposes it is used today and the total nuclear power plants in the world have been tried to be explained in a comparative way. While the international public opinion regards nuclear energy's being cheap and not emitting carbon as an advantage, there have been a serious concerns for the safety and security of nuclear power plants. Among these concerns, with the latest technology, the tendencies of the terrorists to target nuclear power plants that are vulnerable and can cause massive disasters have been the leading reasons. Prominent international organizations such as IAEA, UN and ICJ have been working for the safety and peaceful use of nuclear power plants that are both binding and advisory, such as the Paris Convention, the Vienna Convention and the NPT. Cybersecurity of nuclear power plants has become increasingly important in recent times and is an area where international law couldn't fully form a legal framework. This study, consisting of three parts, examines the development of nuclear energy, international legal principles and cyber security of nuclear power plants, and tries to develop a hypothesis on this subject.
