Okay the reactor core MIGHT sill be contained but you still probably have a huge fire, inaccessible critical machinery and tons of damage to other essential equipment surrounding the reactor, like coolant valves. Besides, if you avoid the reinforced reactor and take out, say the control room or a cooling tower you can cause enough damage to shut down the power plant for some years.

Right. You can cause a good deal of power loss and property damage. It would be costly.
