Venting the station's air into space will require an attack team to kill mutants leaving the corridor to ensure that none of them get to void suits or hide in pressurized compartments.  Of course, you could just vent the area to clear the vault corridor, then seize the gold and leave the system, but that route will cause you not to score the 100 achievement points for restoring Attica station.  You'll still be able to claim the 50 achievement points for fixing the orbital defenses and distributing the ammunition, though.<br/><br/>If the group had assault sentinels, that would probably be the best plan A they could come up with.  The flaming heretics plan is kind of lousy, but it does have the advantage of not particularly exposing the PCs and their assets to much risk.<br/><br/>I won't be going ahead with the assault until the PCs and their positions are accounted for.  (likely including a post from Creeper)
