The Philippine Research Reactor-1 (PRR-1) is a research reactor that is owned and maintained by the Philippine Nuclear Research Institute (PNRI) in Quezon City, Philippines. The PRR-1 is the first nuclear reactor and the only operating nuclear facility in the Philippines. The PRR-1 initially operated as a critical reactor from 1963 to 1988 and the facility became dormant for 34 years. A new subcritical reactor, the Subcritical Assembly for Training, Education, and Research (SATER), was setup within the facility which was first loaded with nuclear rods in June 2022.
