Seems impossible to make it meltdown and explode. Shutting off the coolant just makes it automatically SCRAM. No incoming tsunamis threaten to swamp your diesel generators, no xenon pits to slowly climb out of. Booooring. ;-)
I am one of the programmers that worked on this port back in 2013, I can assure you that we (the programmers) also wanted to make a scenario where the plant would explode, however given it was designed to promote nuclear technology to school children (generally speaking), the people funding the project were not so keen to have nuclear technology shown off in that way!
My biggest beef with nuclear (and I've always said this) is its just so unsexy. No mushroom shapes, no passionate explosions followed by restful oblivion at the end. Its just reliable and faithful and keeps on pluggin' away. I like to live a little dangerously, and you should too!
Nuclear isn't just reliable and faithful and just keeps on plugging away- the modern reactor designs require extraordinary engineering to be reliable and require continuous maintanence and monitoring.
I'm not so sure. There was a news article today about a leaky storage site for nuclear waste, coincidentally not too far from Manchester. [0] There are more ways than explosions to cause ecological devastation.
