Emergency power supply

The emergency power supply system in a nuclear power plant is a critical safety feature designed to provide backup power in the event of a primary power loss. This system ensures that essential safety functions, such as reactor cooling and control systems, remain operational during emergencies. It typically includes diesel generators, batteries, and uninterruptible power supplies (UPS). Diesel generators are the primary source of emergency power, capable of starting up quickly to supply electricity to vital systems. Batteries and UPS provide immediate power during the transition period before the generators come online. The emergency power supply system is designed with redundancy and diversity to ensure reliability, with multiple independent power sources and pathways. Regular testing and maintenance are conducted to ensure the system's readiness at all times. The ability to maintain power during emergencies is crucial for preventing reactor overheating and ensuring the safe shutdown of the plant if necessary. This system is a key component of the plant's overall safety strategy, providing peace of mind and protection for both the plant and the surrounding community.

For the emergency power supply, KROHNE offers a range of measuring and monitoring devices that are crucial for the safety and reliability of the systems. These include flow meters for monitoring the coolant flow, level measuring solutions to control fuel or lubricant oil levels, pressure transmitters for monitoring the pressure in emergency cooling systems and hydraulic systems as well as temperature transmitters for monitoring the temperature in emergency power generators and cooling systems. Highly accuate, reliable and robust, these devices are suitable for extreme conditions.

In addition, KROHNE offers solutions for monitoring vapour and gas flow as well as water quality in cooling systems. Analytical sensors for monitoring various chemical parameters in emergency power and cooling systems round off the range. These sensors have integrated transmitter technology and enable a direct connection to control systems.

The use of these devices in the emergency power supply is advantageous as they ensure continuous monitoring of critical parameters and thus increase safety in the event of an emergency. The high quality and robust design of the devices ensure a long service life and minimise downtime. They also fulfil international standards and regulations and can be seamlessly integrated into existing monitoring and control systems. For detailed information and specific applications, it is advisable to contact KROHNE directly or consult their technical documentation.
