The reaction rate increases.

Explanation: "Supercritical" means the neutron multiplication factor k > 1, so each generation produces more neutrons than the last. Neutron population (and thus fission rate and power output) grows exponentially. It does not imply less energy, increased fusion, or fewer neutrons.
