The Philippine Research Reactor-1 (PRR-1) is an inactive research reactor for decommissioning in Quezon City, Philippines. The PRR-1 is the first nuclear reactor in the Philippines.

The Philippine Research Reactor was built under the Atoms for Peace nuclear research exchange program of the United States.[1] The reactor which had its first criticality in August 26, 1963,[2] was built by U.S. firm General Atomics and was originally a 1MW open general-purpose reactor.[1]

The Philippine Atomic Energy Commission (PAEC; then name of the Philippine Nuclear Research Institute) decided to convert the reactor into a TRIGA Mark III reactor in 1984. The converted reactor achieved criticality in April 1988.[2] It had a capacity of 3MW and has the ability to use low-enriched uranium instead of highly enriched uranium. On the same year, the reactor pool had a leak which led to the reactor being shut down. There were plans to repair the reactor with collaboration with the International Atomic Energy Agency but such plans were abandoned.[1]

In 2005, it was decided that the reactor would be decommissioned.[1]
