Most nuclear accidents aren’t melt downs. They’re steam explosions and releases of irradiated material. It’s great that they built such a failsafe for meltdowns but steam explosions have a bad habit of blowing holes in the containment system. Much less the idea of a steam explosion happening dockside or on something like a natural gas ship.

The only way it would be even close to trusted is if this Chinese ship only visits ports they can strongarm into accepting it and/or they use their military naval technology and have military personnel manning the engineering spaces.
