In the extreme Russian north a team of engineers are ready to dismantle the a Typhoon-class submarine-the world's largest nuclear submarine, the Typhoon. Int its heyday, this monster sub was a terrifying weapon of war-it prowled the oceans of the world armed with 20 deadly nuclear missiles. Now that the Cold War is over, the Typhoon is ready for demolition. But dismantling a submarine with two nuclear reactors is a risky mission. It will take the team over a year to remove the radioactive nuclear fuel, move the submarine into the dry dock and cut its hull into pieces small enough for recycling.
