Since I'm experimenting with nuclear reactors, I wanted to see how devastating a nuclear blast really is and what counter measurements I need to take (2 Layer Reinforced Stone? 3 Layer?)
The result was a save game with a nuclear test site, featuring two 6-chamber nuclear reactors (IC2) for controlled experiments.
Test Site A is located in a desert surrounding, simulating a "normal" environment.
Test Site B is located on a 48x48 stone cube to get repeatable results in a controlled area.
Both sites are monitored and switched on/off from a center control room.
For the lulz I did a test explosion with a fully filled 6 chamber reactor (quad cells):
I attached the save file in case others want to use it as well. I created it with Tekkit Lite, but it might work with other IC2 installations as well (not tested though).
Have fun!
