The 20-tonne reactor support ring has arrived and will be installed at a height of 11 metres in the reactor shaft, supporting the weight of the reactor vessel, which can reach 1000 tonnes when combined with equipment and fluids.
The ring, made of high-strength steel alloys, is a "key and vital component ... it transfers the entire weight of the vessel, including its equipment, nuclear fuel, and operating fluids, to the concrete base in a balanced and safe manner.
Egypt’s Nuclear Power Plants Authority (NPPA) highlights the ring's importance in ensuring the reactor's stability during operation and contributing to load distribution and resistance to internal pressures and earthquakes.
