Nuclear Reactor

Nuclear Reactor (EU mode). Turned on with redstone (on the reactor or a chamber). It has 3 columns of 6 slots; each Reactor Chamber touching its faces adds one column (up to 9). Every second fuel rods give 5 EU/t per neutron pulse plus heat; vents, exchangers and cells handle it. What they do not absorb goes to the hull: up to 10,000 hU plus what platings add. From 40% it sets fires around it, at 50% it evaporates water, at 70% it irradiates nearby creatures, at 85% it melts blocks and at 100% it explodes. The GUI shows hull heat and EU/t. The energy packet is everything it produces: a big reactor needs higher-voltage cables.
