As others have pointed out, this is a 53 year old design. Not exactly the best example for modern nuclear power.
New reactor designs implement passive cooling that allows for 0 interaction for 72 hours. 72 hours is more than enough time for manual intervention to be possible.
>The design is intended to passively remove heat for 72 hours, after which its gravity drain water tank must be topped up for as long as cooling is required [1]
