A definition of criticality, a practical one that I used to determine
criticality, was "a constant positive change in neutron population
(Start Up Rate) with no reactivity addition."  Subcritical
multiplication and spontaneous fission might explain "fresh" I-131 but
the whole spectrum of fission fragmants should be present and as
detectable.

TEPCO graphs of radioactivity-versus-time in water under each of the six reactors show an ongoing nuclear chain reaction creating high levels of "fresh" I-131 in Unit 2, the same reactor pressure vessel (RPV) with a leak path to reactor floor, aux building, and outdoor trenches, that is uncontrollably leaking high levels of I-131, Cs-134, Cs-137 into the Pacific Ocean.
