No. Being at the bottom of a mile deep hole in bedrock makes a very effective isolation.

No. Being at the bottom of a mile deep hole in bedrock makes a very effective isolation.
- cyberax 4mo agoIsolation from _what_? If you reactor melts down, it will contaminate the water column above it. And by having it inside the shaft, you won't be able to do any maintenance on it. It's a stupid idea designed to filter out investors who are stupid enough to fall for it.
- UltraSane 4mo agoactually you just pump the water into a tank. You can also pull the reactor up on a cable if needed.
- consensus1 4mo agoHow does your reactor melt down if it is submerged in coolant?
- cyberax 4mo agoIt boils off the coolant, creating a vapor lock, then water-zirconium reaction happens. Then it explodes and ruins the shaft. So you'll have to drill a rescue well, and then defuel the reactor to avoid any possible contamination. Again, this is a monumentally stupid idea for no reason whatsoever. And modern reactors are already passively safe. Even if the core melts down, it'll be contained in a core catcher: https://en.wikipedia.org/wiki/Core_catcher https://en.wikipedia.org/wiki/Core_catcher
- consensus1 4mo agoIt boils off a 1 mile deep water column? And you don't need a core catcher when you are already 1 mile deep in bedrock. It just goes to the bottom of the hole.
- cyberax 4mo ago> It boils off a 1 mile deep water column? Yes? > And you don't need a core catcher when you are already 1 mile deep in bedrock. Yes, you do. Because if the shaft explodes or gets blocked near the top, the fission products can travel up the water column.
- consensus1 4mo agoSo this thing is just boiling off water from the mile deep water column, and nobody things "hey maybe we could add some more water"? How does a shaft "explode"? What is generating the explosive force?
