Soviet era plants don’t have containment shells. I don’t know about this one though.

I'm certainly no expert, but I read a little bit about it before I commented. The reactors here do have a building intended to serve as containment. I didn't really see much assessment of how robust it is.

This is from last week and discusses the practical impacts of war around the plant being a major issue even if the plant isn't involved:

That article briefly mentions this page, where the CEO of Ukraine's nuclear operator states that they are protected:

"In addition, Ukrainian power units are ready even for an aircraft crash, because the containment and the reactor vessel designed to withstand corresponding risks."

Russia doesn't need to control the immediate areas around nuclear plants in the initial phases of their invasion, it's lunacy that they aren't carefully avoiding them.

We are over a week in, I think this is beyond the initial invasion timeframe. Russia has faced fierce resistance so I can understand a desire to weaken that defense.

It’s a lot harder to stage a defense when you have no electricity. Strategically it makes a lot of sense for Russia to overtake or shut down the power grid. If they do that with physical damage then there’s no need to control the immediate vicinity.

Why not just cut the transmission lines?
Because they would have to occupy the area where the lines were cut to prevent repairs? I don't know. I'm not justifying what Russia is doing, but it isn't surprising.
This one has a smaller core than a RBMK so it was cheap enough to have a containment shell that the Soviets were willing to pay for one.
