DIN EN IEC 63046:2022-02: Nuclear power plants - Electrical power system - General requirements (IEC 63046:2020); German version EN IEC 63046:2021

This standard specifies requirements and recommendations for the entire electrical power supply. In particular, it addresses non-uninterruptible and uninterruptible power supplies, including systems supplying instrumentation and control systems. It describes the specification and requirements for a suitable system of electrical power supply for reactor safety systems in a nuclear power plant at a high level of abstraction. Similarly, it enables electrical power generation to supply active power, reactive power and electromechanical inertia to the interconnected power system. It describes the interrelationships between: - the safety requirements of the power plant and the architecture of the entire electrical power system and its subsystems, including the contribution to the plant's defence in depth and the measures for independence and redundancy; - the electrical requirements and the architecture of the electrical power system and its subsystems; - the functional requirements and the architecture of the electrical power system and its subsystems; - the requirements related to the maintenance strategy and the architecture of the electrical power system and its subsystems. Furthermore, it contains requirements for the design of the electrical subsystems, requirements for auxiliary and supply systems (air-conditioning, ventilation and control systems and so on) and the overall framework of the life cycle of the electrical power supply.
