Implemented Nuclear Reactor Meltdown

I've been told that when nuclear reactors meltdown, they don't damage blocks...However, i've had bad experiences with them blowing up bases and being used for griefing. Could a staff member please take a moment of their time to test this and see if they do indeed not blow up blocks?

 

However Big Reactors don't only IC2

 

uhuhuhuhuhuhuhuhuhuh uhuh uh yhea "players can't greif with it" was this before or after my base?

 

but we placed the reactor while there was a protection next to it? so you fixed that? or no? cuz 1 quad core does that much damage, a full set i think reachs quite far
