Reactor fitness check:

8x8x8 area surrounding the core must either contain..
|
|
Water source nodes
|
|
Neutron Absorber (with active medium)
|
|
Fluid Port (with COLD coolant available)
|
|
Also acceptable nodes:
|
|
Any fluid transfer conduit
|
|
Any reactor component
|
|
Unacceptable nodes (These raise heat INSTANTLY!):
|
|
Lava source
|
|
Hot coolant
|
|
..in order to keep the heat below critical. Any other detected node will either be MOLTEN or ACTIVATED (TODO) (you don't want this!)
|
|
Reactor core will be replaced by a molten core when the heat reaches 100%. All components and fuel will be lost!
