They did explode Main Generator Gas and no I never stated they wouldn't need Containment Flooding WHICH BTW is an EOP step at Fukushima not a SAG.
Aren't you the guy who has no practical experience at a BWR and hasn't qualified Shift Manager? Do you need the concept of Support System explained to you?
Frigging NUBs
these are all yours, and every single one has proven to be wrong:
that looks more like a turbine building explosion to me that blew away the blowout panels on the refueling floor. wanna bet they released hydrogen from the generator and it went poof?
check out the explosion, looks exactly like a generator h2 release.
i'll guarantee they are not flooding containment.
once they covered the core none of that was credible.
and they did cover the core.
the explosion emanated outside containment and it looks like the blowout panels did their job.
there is no mechanism for getting hydrogen inside the secondary containment and a internal drywell explosion is impossible.
