That requires generating and burning keys to devices during manufacturing. This process will be hacked by NSA & all, exactly like Gemalto https://www.theguardian.com/us-news/2015/feb/19/nsa-gchq-sim...

Cell processor shipped for commercial installation in the IBM Blades QS20/QS21/QS22, which was based on Roadrunner supercomputer.
Sony also demoed rack-mount with Cell (https://en.wikipedia.org/wiki/Zego) but it is not clear that it was available in open market

Turn of millennium was era before of SSL/TLS. Livejournal did not want to send clear text password during login to the site. SRP was patent encumbered (and anyway implementing proper PAKE in JavaScript of that era was unfeasible).
So at Livejournal implemented their own challenge-handshake auth: https://www.livejournal.com/doc/server/ljp.csp.auth.challres.... Unfortunately it require storing plain-text equivalent of password on the server.
Seems to be worked fine through the years, but they used it well past "best before" date.

The usual problem is not shutting down the reactor: both TMI and Fukushima was properly shutdown. Important task is cooling down the core (and SFP) after that.
Left on its own, halted thermal reactor generates hundreds MW of heat after shutdown. That heat destroys cladding of fuel, generates explosive Hydrogen and causes meltdowns of former core.
It is believed that ATF, core catchers and electricity-independent passive cooling will reduce risk of this types of incidents, commonly called LOCA - Loss of coolant
