seems it usually happened at lesser depths, and for ones deep enough to contain debris, the main effects were geological, from the actual explosion? not what i expected tbh
I'm not sure how this question would be relevant. Nuclear bombs are impractical for power generation and a nuclear reactor is not ever going to turn into a nuclear bomb.
"Project PACER, carried out at Los Alamos National Laboratory (LANL) in the mid-1970s, explored the possibility of a fusion power system that would involve exploding small hydrogen bombs"
