BONUS (Boiling Nuclear Superheater) was a prototype nuclear power plant at Punta Higuera, on the northwest side of Rincon, Puerto Rico. It was a joint project of the U.S. Atomic Energy Commission and the Puerto Rico Water Resources Authority, built to test a boiling reactor that superheated its own steam.

Construction started in 1960. The reactor reached its first controlled chain reaction on April 13, 1964, was first connected to the grid on August 14, 1964, and reached full power in 1965. It was permanently shut down on June 1, 1968, because of technical difficulties and the costly modifications they would have required. During 1969 and 1970 the fuel and highly activated parts were shipped to the mainland, and the reactor vessel was entombed in concrete inside the dome-shaped building.
