I believe they tried to inject some chemicals to slow the reaction, but the pump and/or valves failed and clogged.

I was thinking maybe have those chemicals sitting in a glass or temperature sensitive container inside the tank. So when there's too much pressure or heat, the container containing the neutralizing chemical is broken like a fuse and the chemical is automatically released.

That is active.

Something passive could be submerging the tank in a pool of water (also good for proving spill containment won't leak).

Typically you don't have enough surface area for that. The walls are thick enough that thermal conductivity into an ambient-temperature liquid alone is not going to be sufficient.

Uh, you can't just disconnect a pressurized 35,000 gallon tank and drop it into a an enormous pool you just keep full under it at all times.

Riiight. That is exactly what I was thinking.

I think the passive version is the tank stays in a pool all the time.
