I GWt equivalent with the burning of 125 tonns of coal in every hour.
You want to remove that energy with natural airflow, or with the water dripping out of walls?
It can evaporate 1000 tonns of water in every hour.

In your ground plant, don't you remove that energy with natural airflow (the air around your plant)? If you can do that, why can't you do it even better through water and rock? You know water and rock is many times (tens to hundred) more efficient heat conductors than air? In air of 30 degrees, you feel hot but not life threatening, but if you stay in 30 degrees of sea water without suit you will feel cold in half an hour and probably die in a few hours.
The water drips constantly through the mountain, they don't stay statically (which will evaporate eventually), that is how water cooling works, any type of cooling. When your plant on the ground, it still has to have the same amount of heat being removed by the surrounding air PASSIVELY, relying on natural circulation. That circulation is much less efficient than water and rock where the water ACTIVELY passthrough because of gravity, that is like constant wind that you may not have on the ground.
To get what I am talking, you can search for video report about China building a highway tunnel through mountain of the same region. Watch and listen to the water flooding trouble they faced. The water comes from the mountain before the tunnel was drilled, so it goes out of the tunnel back to the mountain, that is natural water circulation that I am talking about.
In a simplistic analogue, your ground plant is an ordinary fan based air-cooling PC, my plant is a pumped water-cooling gaming station.

At a minimum, commercial nuclear fuel can be used to generate bomb grade materials, otherwise the notion of countries with nuclear powerplants but no weapon systems weaponizing their Pu stockpiles wouldn't even exist. Separation of Pu-239 from reprocessed spent commercial fuel may require greater processing to achieve ICBM grade material, but it is still doable. In any event however, such a capability is only intended to be complementary to dedicated Pu generation plants and not a pure substitute.
Japan has a huge stockpile of Pu. I don't think they produced them using a dedicated reactor

I don't think it can be used for weapon, not weapon grade Pu
You can make bomb from commercial grade Pu, but it will be heavy, and inefficient.
Additionally the reprocessing needs expensive machines, and very difficult ( the weapon Pu reactors output can be handled with gloves).
It means the delivery of such weapons not possible with missiles, or bombers.
Maybe with ships. Or these can be used as mines.

or as a dirty bomb
Perhaps just better to use U-235 than commercial grade Pu
Perfect material for dirty bomb is the Cs137, if someone reprocessing fuel anyway.
It can be obtained from dismantled gamma sources, like radiotherapy machines, maybe RTGs?
Soluble in water, very strong gamma emitter, and has 30 years of half life.
The biggest contamination from Fukushima (and Chernobil) is the Cs137.
Theoretically doable, but in practice impossible.
It is hard to separate the U235 from the U238, but there is only one neutron difference between the Pu-239 and Pu-240.
Means it is extremely difficult to separate them from each other.
