Warships have a “battle short” on some critical equipment, which will bypass safety equipment like fuses. If your gun turret traversal motors pull too much current in the middle of a battle, you’d rather risk damage or fire to have them keep working rather than disable themselves to protect from a fault. Total speculation here, but it would make sense for military reactors to have something similar, to put them in a mode where the threat of a reactor accident due to a malfunction is less than the threat from the enemy if it goes down. https://en.wikipedia.org/wiki/Battleshort
Likewise commercial aircraft have bypasses on the fuel and oil filters in case they get clogged in flight. The engine will need a thorough inspection if this happens but it's better to damage the engine if it gets you to the nearest airfield.
I’ve never been in the Navy or on a submarine, but my impression is that SUBSAFE is about never ever having a reactor accident, at least partially for PR reasons. It wouldn’t surprise me if there simply are not procedures to deliberately put the reactor in a dangerous state.
The Navy may have done the math and determined the loss of a boat to the enemy is a less bad thing than the loss of a boat to a “nuclear accident”.
I desperately hope for and welcome anyone with experience in the space to correct me.
