A small step in reactivity does not blow the power up instantly, because a fraction of neutrons are released with a delay. Those delayed neutrons slow the response to a controllable timescale — the reactor period. But push reactivity past the delayed fraction β and it goes prompt-critical, growing on the neutron lifetime — millisecond-fast and uncontrollable.

Reading this result: Positive but below β — delayed neutrons stretch the response onto a stable, controllable reactor period.
