en.wikipedia.org back for a bit.. that link will explain the fuel corium and melt times through the vessel bottom head

look under the section reactor vessel breaching ...

During the Three Mile Island accident, slow partial meltdown of the reactor core occurred. About 19,000 kg of material melted and relocated during about 2 minutes, about 224 minutes after the reactor scram. A pool of corium formed at the bottom of the reactor vessel, but the reactor vessel was not breached.

yeh.. I remember that Reed .. I was thinking up to 24 hours if my memory is right

interesting radioguy.. my memory says about 30% of the TMI core melted.. can't remember how many tons.. something like 130 or so was eventually removed and moved to Idaho site where I worked..

Angie.. no sweat because I"ve heard different numbers depending on the specificl conditions.. a lower percent melt would take longer..

interesting point on TMI...At 6:56 am, a plant supervisor declared a site emergency, and less than 30 minutes later station manager Gary Miller announced a general emergency, defined as having the "potential for serious radiological consequences" to the general public.In a 2009 article, Gilinsky wrote that it took five weeks to learn that "the reactor operators had measured fuel temperatures near the melting point".[30] He further wrote: "We didn't learn for years—until the reactor vessel was physically opened—that by the time the plant operator called the NRC at about 8 am, roughly ½ of the uranium fuel had already melted. THAT WAS ONLY ROUGHLY OVER AN HOUR... TMI was able to restart pumps and take emergency procedures but the core had already melted by that time

good one radioguy... PRIME MINISTER SAYS.. get those fuel elements back to the original shape quickly ..

very good anon.. see.. you were there .... good info and appreciate it

I always wondered what really happened.. because it always sounded like there were some mad people between the plant, company and nrc
