The research reactor is a 1 Megawatt (MW) swimming-pool–type reactor housed within a dome-shaped containment building.

The reactor first achieved criticality on January 2, 1975 and has since undergone continuous upgrades. Major milestones include the conversion from Highly Enriched Uranium (HEU) and Low Enriched Uranium (LEU) fuel in 2000, a control system modernization in 2003, and ongoing facility enhancements such as the Fast Neutron Irradiator (FNI).

In 2025, the reactor celebrated its 50th anniversary of operation, marking half a century of safe and reliable service for research, education, and industry.

The complex supports controlled exposure and testing using both gamma and neutron radiation, with operations carried out by a team of highly trained staff and students.
