Technical Specifications

The ETRR-1 reactor is a research and training nuclear reactor located at the Nuclear Research Center in Inshas, Egypt. It was supplied by the USSR and arrived in 1958, with commissioning occurring in 1961. The reactor is situated 40–60 kilometres northeast of Cairo. It serves as the first nuclear reactor in Egypt, providing a platform for neutron physics, materials testing, and isotope production.

Reactor Parameters

The ETRR-1 is a light water-moderated, light water-cooled reactor. The thermal power capacity is 2 MW. The primary fuel source is uranium. The reactor design is a horizontal pool-type reactor, which is typical for early Soviet-supplied research reactors of this class. The core configuration allows for multiple experimental positions for neutron flux utilization. The cooling system relies on natural circulation or forced convection of light water, which also serves as the moderator. The reactor vessel is housed within a concrete biological shield to protect against gamma and neutron radiation. The control system utilizes control rods inserted vertically into the core to manage reactivity and criticality. The reactor operates at a relatively low pressure, close to atmospheric levels, which simplifies the primary circuit design compared to power-producing pressurized water reactors.

The reactor core is designed to provide a high neutron flux for experimental purposes. The fuel elements are typically arranged in a lattice structure to optimize neutron economy. The reactor includes a reflector, usually made of beryllium or graphite, to bounce neutrons back into the core, enhancing the flux distribution. The experimental facilities include a central thimble for irradiation and several peripheral positions for various neutron beams and sample holders. The reactor's design allows for flexibility in fuel enrichment levels, although the specific enrichment percentage is not detailed in the primary source. The reactor's operational status remains active, contributing to Egypt's nuclear research capabilities. The facility supports both academic and industrial research, leveraging the neutron source for material characterization and isotope production. The reactor's longevity is attributed to regular maintenance and upgrades to its instrumentation and control systems. The ETRR-1 continues to be a key asset for the Egyptian Atomic Energy Authority in advancing nuclear science and technology in the region.
