Nuclear safety and security hold significant importance in our current world, especially after the proliferation of nuclear weapons, due to the risks and disasters they pose to human life. Therefore, the International Atomic Energy Agency (IAEA) has focused extensively on this topic. Nuclear energy is a contentious and important source of global energy, offering vast potential for high-efficiency electricity generation. However, it simultaneously raises concerns regarding safety and security. Nuclear safety is a critical aspect that must be carefully considered and understood when discussing and evaluating the use of nuclear energy as an option to meet global energy needs.

Nuclear energy involves harnessing the energy released during nuclear fission processes of atomic nuclei to generate heat that can be converted into electricity. Nuclear energy is known for its high efficiency and ability to generate large amounts of energy from small quantities of nuclear materials, reducing carbon emissions and enhancing the sustainability of energy systems.
However, nuclear technologies also raise safety concerns due to past accidents such as the Chernobyl disaster in 1986 and the Fukushima accident in 2011. These incidents underscore the utmost importance of ensuring safety in the design and operation of nuclear reactors.
Definition of Nuclear Energy:
Nuclear energy involves the use of energy released during the dismantling of atomic nuclei of chemical elements and is one of the most powerful sources available for generating electricity. Nuclear energy is primarily generated through two main processes: nuclear fission and nuclear fusion.
Nuclear fission occurs when the nucleus of a heavy atom is split into smaller nuclei, releasing massive amounts of energy and neutrons. This process is controlled in nuclear reactors to continuously generate electricity.
On the other hand, nuclear fusion is the process where nuclei of light atoms fuse to form heavier nuclei, as occurs in the sun and stars. Fusion is explored as a potential solution for clean and massive energy generation but requires highly complex technologies and high costs at present.
Current nuclear reactors, which rely on nuclear fission, are essential for electricity generation in many countries worldwide. These reactors use nuclear fuel rods (such as uranium or plutonium) to induce nuclear fission, with cooling by water or gas to transfer heat to power turbines for electricity generation.
Despite the benefits of nuclear energy in terms of its high efficiency and low greenhouse gas emissions, it faces significant challenges in terms of safety and nuclear waste management. Nuclear safety is a crucial issue requiring precise engineering design and strict oversight to prevent accidents like Chernobyl and Fukushima, while nuclear waste requires permanent and safe solutions for disposal.
In conclusion, nuclear energy represents a crucial source of global electricity generation, with unique advantages and challenges that necessitate broad discussion and continuous innovation to enhance safety and sustainability in its use.
Definition of Nuclear Safety:
Nuclear safety is defined as the efforts and measures aimed at protecting humans and the environment from potential risks associated with the use of nuclear energy. Nuclear safety includes designing reactors and nuclear facilities to withstand external pressures such as earthquakes and floods, implementing strict measures to ensure the safety of operations, and safely and effectively managing nuclear waste. Additionally, nuclear safety includes developing comprehensive plans to handle emergencies such as nuclear material leaks and ensuring the existence of legal and regulatory frameworks to monitor nuclear energy activities and ensure compliance with the highest safety and security standards. These efforts require international cooperation and continuous commitment to developing best practices and technologies to enhance nuclear safety and ensure the sustainable and safe use of nuclear energy for the future.
International Agreements Related to Safety:
The Basic Convention on Atomic Energy:
Established by the International Atomic Energy Agency (IAEA) in 1957, this convention serves as the basic legal framework for the organization's work. The convention aims to achieve international cooperation in the peaceful use of nuclear energy while maintaining safety and security.
Nuclear Safety Standards (Basic Safety Standards):
These standards are a set of principles and guidelines applied to various nuclear activities, such as designing and operating nuclear reactors and managing nuclear waste. They aim to ensure public safety and protect public health and the environment.
Convention on the Safety of Nuclear Waste Management:
Aims to provide an international framework for nuclear safety in the management and storage of nuclear waste. It includes standards and guidelines for the safe and effective disposal of nuclear waste.
Convention on Nuclear Transport Safety:
Sets safety standards for the international transport of nuclear and radioactive materials, focusing on protecting workers, the public, and the environment from any potential hazards.
Convention on Early Notification and Assistance in Nuclear Emergencies:
Aims to enhance international cooperation in dealing with nuclear emergencies, providing a framework for early notification, rapid exchange of assistance and information.
These international agreements and standards are integral parts of the international community's efforts to enhance nuclear safety and ensure the safe and responsible use of nuclear energy, while maintaining public health and the environment and enhancing public confidence in this technology.
Key Challenges to Nuclear Safety:
1.Safe Engineering Design:
Nuclear reactors require precise engineering to withstand external pressures such as earthquakes and effectively deal with potential accidents such as nuclear material leaks. Effective cooling systems and insulating materials must be provided to ensure cooling continuity and prevent emergencies.
2.Nuclear Waste Management:
Safe disposal of nuclear waste is a major challenge. This waste includes radioactive materials that require long-term storage and strict measures to minimize their environmental and health impacts on local communities and the environment.
3.Operational Safety:
Strict procedures must be put in place to ensure the safety of nuclear reactor operations, including rigorous control over cooling operations, nuclear fuel management, and active material management.
4.Oversight and Legislation:
There must be strict legal and regulatory frameworks to monitor and review nuclear energy activities, ensuring operators' compliance with international safety and security standards.
These challenges require broad international efforts, including cooperation between countries to develop and exchange best practices and technologies in the field of nuclear energy. Safety and security must be top priorities in every aspect of nuclear energy use to ensure protection of humans and the environment from any potential hazard.
