Two of the six reactors at Zaporizhzhia were shut down a few days ago. Presumably those reactors were safed. Which leaves, of course, four nuclear reactors controlled by a control room that has spent the last hour burning.
But really, these reactors should be inherently safe. That is, safe from a failure of control. Damage to the cores themselves and (insert scary shrug).
There is also a good deal of low and medium level waste stored at the site, as well as spent fuel. None of that needs to be scattered around by an explosion.
