But the meltdown could easily resume if they cannot continue present emergency measures. How do we calculate the time to cold shutdown in a reactor where there has been a partial meltdown. Seems we need better definitions of "partial". It matters whether the rods have cracked and the pellets have been exposed to sea water or whether the pellets have fallen out and collected on the bottom where recriticality is conceivable, especially in #3, with MOX fuel.
