I tried this idea. The problem is that most chest freezers don't have a good way to deal with the accumulated condensed water and the water builds up at the bottom of the chest freezers.

1. The LFTR fans think an inherently low breeding ratio is a good thing and always advertise "non-proliferating" as a feature.
This of course makes the design very delicate (or unreliable if you like) in terms of neutron balance.
It also makes the LFTR dependent on some external source of fissile material.

2. and 3. are also true.

4. is what worries me most. The cracks and corrosion are not a trivial problem and have never been shown to be solved.
The presence of dissolved fission fragments means you are running a very complex chemistry experiment with your pipes and pumps.
Most of our experience is with solid fuel where the fission fragments are well contained. It's going from one extreme (well controlled) to the other (worse possible case for fission fragment attack).

Your 20 year time frame seems like a minimum to me. We need to add to that the time required to round up funding.

How many civilian LFTR anywhere?

Maybe GE thinks they're so smart their sodium reactors will never leak.
Personally, I have my doubts.

Every sodium reactor ever run has had a leak.
And a leak of radioactive molten sodium is always a serious leak.
This makes the industry look very bad.

You could, and the Soviets did, use liquid lead as a coolant and neutron reflector.
They powered their fastest submarines with them. There were a number of failures related to letting the lead cool off and solidify when the submarines were docked but adding some electric heaters for startup should solve that.

It's not clear an LFTR can run at temperatures suitable for a Brayton cycle.
There are enough worries about corrosion without raising the temperature.

That example involves breaking the problem down into smaller steps.
Instead of subtracting 7 in one step, you do it in two steps, 5 and then 2.
You subtract 5 first, as 15-5=10 is easy to remember.
Then 10-2=8 is also easy to remember.

Did you include the cost of electricity?

Worse yet, the energy to pump those lasers was much higher.
The 1.8 megajoules of laser power were the output of pumping the lasers with 422 megajoules. And conversion from thermal to electric power is around 33% so there would need to be about 1266 megajoules of thermal power to produce that 8000 joules.

This is an inertial confinement system which means the lasers make it blow up.

Earthquakes are a symptom of built-up stress, a result of a continuing natural process (movement of tectonic plates). As you know from your choice of the word "induces", the boreholes are relieving stress which would otherwise be released later in a more violent way.

This is a good thing.

CO2 is easily liquified at room temperature with moderate pressure. Once liquified, just open a valve at the bottom of the tank to drain out the liquid CO2, closing the valve afterwards.

I wonder how easy it is to separate the iron pellets from the coal ash at the scale of a large power plant, which is about one million pounds of coal per hour.

Did you read the reports of the Accident Investigation Boards?
