It was April 26, 1986, I was walking into the Chrenoble power plant, in Ukraine. Today I was set to conduct a safety test of the backup cooling system on reactor no 4. To conduct this test, we will first put control rods in between the rods containing nuclear matter. Then, we will then fill the main chamber with coolant fluid, via the backup cooling system. I then proceeded to the reactor to conduct the test. I reduced the reactor to 25% power then, the reactor power plummeted to 1% and having a great risk of shutting down. Then, we sent more power to the reactor, to keep it running. For the moment, the reactor seemed “stable”. After that, we inserted the control rods, and turned on the backup cooling system, with failed. Then the reactor received a great power surge. Then the heat in the system soared and produced more steam then the system could handle. The 3500 megawatt system was now operating at 35000 megawatts. The 1-ton rods on the top of the system started to jump up and down, then they blew completely off. One worker said, ”You could feel the shockwave throughout the building.” At that moment the 1000 ton biological shield blew off, and everything went dark.
