This reactor is well suited for duplicating the fuel performance of power reactors. The core consists of low-enriched Uranium pins intended to be very similar to what is used in commercial nuclear power plants. Five beam ports are adjacent to the core of the reactor. This reactor is well suited for experiments requiring a large neutron flux because peaking occurs around the edge of the core due to under moderation. In September 2007, students, faculty and staff produced the most intense operating positron beam anywhere in the world.
