The problem with uranium burning reactors, is that...

...the fuel is contained in fuel rods within the reactor. Coolant is circulated into the reactor and back out in order to keep the fuel cool and prevent a meltdown. If electrical power is lost to the cooling pumps, then the cooling stops.

Thorium reactors use molten salts, and the fuel is contained within these circulating salts. If power is lost to the pumps in a thorium reactor, then the fuel also stops flowing into the reactor, stopping the chain reaction.

In other words, a Torium reactor fail safe when electrical power is lost. A uranium burning reactor always need to let it flow in order to prevent a meltdown.

Comparing a design like that to an "unsinkable" ship, which is a ridiculous notion to begin with, is unfair.
