Isolation Condenser (IC) operation
Wikipedians,

I've been looking over some of the documentation provided by TEPCO; this in regards to the operation of the Unit 1 IC after the earthquake and the resulting reactor SCRAM, but before the SBO condition created by the tsunami. It seems that the operators deactivated and reactivated the IC several times during this period, and that this is consistent with industry practice insofar as the action is taken to avoid excessive deltas in temperature and pressure and consequent stress to system components on the hot side. I'm still reading and assembling sources in preparation for an edit -- I hesitate to use a TEPCO document as the sole source. Irregardless, I feel the issue of the operation of the Unit 1 IC, which has been hashed and rehashed and gone over with much contention in many quarters, is a very important one. This article seems to misunderstand the utilization of the IC by the operators, displaying the hindsight bias that unfortunately so often accompanies any discussion of the accident. It is a bit of a slur against the operators, who worked selflessly and heroically, under very dangerous conditions, to simply say that the IC could have cooled the reactor effectively for however many hours if it had been left on. This is like saying that the accident could have been avoided if the operators had been clairvoyant and put the plant in safe shutdown a week before the earthquake. They didn't leave the IC on because that would have departed from procedure, and they had no reason to depart from procedure because they didn't know in advance that there was an especially terrible and dangerous tsunami on the way.

Seawater used for cooling
Has history changed ? I remember the following news. Cite: "He (i.e.Masao Yoshida) will be remembered most of all for defying an order from senior Tepco officials in Tokyo to stop pumping seawater into one of the damaged reactors in a frantic effort to keep it cool. Tepco officials were concerned that pumping seawater into the reactors would render them commercially useless." --Robertiki (talk) 01:46, 23 June 2021 (UTC)
