Sabotaging the working of the liquid T reactor to put out accelerated energy does not require explosives.
No, but we got an explicit answer about how much explodeyjuice most methods of sabotage produce and it's no worse than conventional explosives or heavy industrial accidents, measured in tons of TNT not kilotons. The kiloton figure came about specifically in reference to catalyst devices, it's not the default failure state from chucking a wrench in the gears it's the theroetical absolute worst case if Kane comes back and starts handing out catalysts like candy.
