I'm absolutely gutted. Over the course of the last two months or so, of an evening I've been quitely building a nuclear power plant in Tekkit. Tekkit is a technical expansion to Minecraft - it's simply fantastic. I spent ages learning how to wire monitoring systems, keep the reactor cold and work in redundancy so the reactor ran without me being there to watch it.
Unfortunately, tonight, I learnt the hard way what happens when reactors go bad.
I developed four reactors in a immensly deep pit. At the bottom of the pit, I used wireless transmitters to transmit the reactor temperature back to a control room on the surface. It all worked brilliantly and I was most pleased with myself. I decided to develop a lamp-based monitoring system so that in the control room, each reactor had 3 lamps, red, orange and green. Green transmitted at 0 heat, orange at 200 heat and red at 1000. To test this, I had to load the reactor. I loaded up reactor one and turned on a single coolant ring. It was pumping vast quantities of ice and all was well - my reactor was chucking out huge quantities of energy and temperatures were peaking at 250 heat.
The reactor and monitoring system had been running for well over an hour and I was busying myself in another corner of the powerplant - when out of the corner of my eye I noticed the red lamp for reactor one was on...
Holy crap! I ran to the Industrial Information Panel, the temperature was at 4000 and jumped to 6000 in the seconds I spent looking at horror at it. I rushed as fast as I could toward the surface and the control room -- noticing that the coolant pipes were all without ice. Serious ut oh!
Then suddenly, Minecraft gave the half-second lag and I knew what had happened. Reactor one blew up. The blast destroyed all three other reactors -- all the tirelessly created wiring and monitoring equipment and great swatches of the protective shroud I'd carefully built. The destruction was far greater than I imagined it could have been, taking out reinforced walls, windows, doors and complex pipework. With no-way to go back to before the explosion - my plant is lost - I must start again.
Tekkit - what a fantastic upgrade to what is already one of the best games I have ever played.
