Chernobyl's containment is not massive concrete, and cannot sustain a hit from a bomb in any way. The new safe containment structure is metal and air, it's meant to contain dust as the reactor building inside is dismantled.

The old sarcophagus that was build in 1986 only had concrete walls in a few key places. Much of it had huge holes and open areas covered in sheet metal. All of it was falling apart and rapidly deteriorating when construction on new safe containment started.
And remember there are 3 other reactor buildings at the site and none of them are covered by the containment structure or really any protection (Chernobyl's Soviet era design which lacks a concrete containment structure is partly why its meltdown was so catastrophic). The site cannot withstand any attack.
