***We addressed this before: A runaway, sinking nuclear plant which is no longer moderated except by surrounding seawater in an open loop configuration is a radiation heat pump into the environment. The seawater closest to the device quickly turns to steam, ablating away as it rises to the top because it's lighter than the surrounding water, and carries its radiation with it into the open sea. From there, ocean currents could carry the radiation poisoned seawater to multiple places.

1) Reactors SINK. In 20 minutes your precious reactor with it's heat will be on the bottom at the ocean floor. Sure it will leak a LITTLE but after 15 minutes, nothing.

2) Ever seen a volcanic vent ? NO STEAM.

3) There are thermal gradients in the ocean water that prevent what you are talking about. The irridated water would ride up several hundred feet aznd by the top it got to the top it would be at the surrounding seawater temperature again.

Of course in shallows (less than 500m), then there could be some issue, but the fact remains that the reactor core will be well shielded even in shallows.

Of course, there is something else to consider. How exactly are you going to make water radioactive ? Oxygen isotopes ?

A reactor in thermal runaway would take at least several hours to cool down even under the best of conditions, at a minimum contaminating several million gallons of seawater. 2) Ever seen a volcanic vent ? NO STEAM. ***I've seen it on TV. There is steam, but it quickly reintegrates with the surrounding water because of a couple of factors. The open question is at what depth does the steam no longer vent to the open air, which is probably on the order of several hundred feet. 3) There are thermal gradients in the ocean water that prevent what you are talking about. The irridated water would ride up several hundred feet aznd by the top it got to the top it would be at the surrounding seawater temperature again. ***This is exactly the problem. The factor of rising hot water being replaced by inrushing cool water is an open configuration heat pump. As you stated, the "irridated water would ride up several hundred feet". This configuration just keeps pumping radiation into the sea. Of course in shallows (less than 500m), then there could be some issue, but the fact remains that the reactor core will be well shielded even in shallows. ***The danger in the shallows would be that the steam could rise to the open air, creating a radioactive cloud.

Sorry about the HTML problem. This is a duplicate post but easier to read.
