Nuclear island

The nuclear island is the heart of a nuclear power plant, housing the critical components involved in the nuclear fission process. It includes the reactor vessel, where the nuclear reaction occurs, and the steam generators, which transfer the heat produced by fission to the secondary loop. The reactor vessel contains the nuclear fuel assemblies and control rods, which regulate the fission process. The nuclear island also encompasses the pressurizer, which maintains the pressure of the reactor coolant system, and the containment building, a robust structure designed to contain any potential release of radioactive materials. Safety systems within the nuclear island are paramount, including emergency core cooling systems and backup power supplies to ensure the reactor remains stable under all conditions. The design and operation of the nuclear island are governed by strict regulatory standards to ensure the highest levels of safety and reliability. The nuclear island's efficient and safe operation is crucial for the overall performance of the nuclear power plant, providing a steady and reliable source of electricity.

KROHNE provides a comprehensive range of measurement and monitoring devices for the Nuclear Island, essential for the safety and efficiency of nuclear reactors. Key equipment includes highly accurate flowmeters to monitor the coolant flow within the reactor core, or TDR transmitters to control the water level in various tanks and pools. Pressure transmitters also play a critical role by monitoring the pressure within the reactor circuit. They help ensure that systems operate within safe limits and safeguard the integrity of the reactor pressure vessel. Temperature transmitters are equally important, continuously measuring the temperature of the coolant and other critical components. Designed for extreme operating conditions, these devices offer exceptional precision and durability.

To monitor the chemical composition of the coolant and other process liquids, KROHNE provides pH sensors and other analytical instruments. These sensors measure key chemical parameters, contributing to the safety and efficiency of reactor processes.

The deployment of this measurement technology delivers numerous benefits. It enables continuous monitoring of critical parameters, enhancing system safety and operational efficiency. The devices are designed for longevity and robustness, minimising downtime while complying with international standards and regulations. Additionally, they integrate seamlessly into existing monitoring and control systems.
