Quad Fuel Rod (Uranium)

They last 20,000 seconds (about 5 and a half hours). A lone rod gives 5 EU/t and 4 hU per second. Each extra pulse from a neighbouring rod or a reflector adds 5 EU/t, and heat grows faster: 2·n·(n+1) hU with n pulses. The dual rod equals two rods side by side (20 EU/t, 24 hU) and the quad equals four (60 EU/t, 96 hU). Filled in the Canning Machine (Canning mode: enriched uranium fuel + empty rod). Depleted rods go to the Thermal Centrifuge: uranium 238, plutonium and iron dust.
