Now I know nothing about this topic, but I have heard that the reactors will eventually melt down. The only thing I'd question is I'd think it would have happened sooner or not for a while more. The death wave is questionable I realistically don't believe that would happen, and think it was just added for dramatic effect.
If all the nuclear power plan melted down it would not create a death wave but it would release a massive amount of radiation that would make large areas of the world unhinhabitable and that would cause a global ecological disaster, especially in the northern hemisphere were the majority of the 438 (approximative number) reactors are located. It could have serious consequences on our society and could even led to the fall of our civilisation.
The world was already nuke those Reactors should of blow up a long time ago that if i they were not destroy when the rest of the world burn. 100 years plus with no mantiance of any type yea i do not buy that story at all and i do think them using that as a plot hurt season 4 and has hurt the show i think they lost more when they more or less kill off everyone they could.
ALIE said between our time and the first apocalypse, humans were able to build very resistant power plants that could last more than a 100 years (which they did). However the Death Wave is just fictional because every reactor would fail at the same time in the US and the rest of the world, so the wave can't be located on the West Coast and just cover North America from West to East, it would blow up from everywhere
100 years with no Mantiance at all without a single soul going to make minor adjustments yea i do not buy for a second that the reactors would last that long. Also not every reactor would of been built the same i am sure that some would of been older reactors not everyone of them would of had what ALIE claimed. That being said the death wave was one of the dumber ideas in show to me so the reactors were used for that bs and that alone.
The scene which made me stop watching this show is the water generator blast scene ..they need that water generator to keep hundreds of people alive inside the ark after the meltdown but they decide to blast it for saving 25 people ...now instead of hundreds only hundred can stay inside the ark and Clarke decides to allow the guy who made the decision to stay inside the ark with other 99.
"water generator"? Oh, you meant the "Hydro generator" that Monty set off in Azgeda?
Yeah, that's a tough call. You want 25 people in slavery or hundreds in your camp live? I love the show exactly because of those stupid decisions. It is a wrong decision, but I can see why Monty did it.
That thing is not nuclear. So it's actually had nothing to do with the OP.
I think given the latest developments in nuclear technology, yes, it's possible to have nuclear plants keep running for one hundreds years without maintenance. Bill Gates himself invested a company who is doing research on that. However, I don't think the nuclear plants will explode and cause another world wide apacolypse like the TV series depicted. The future nuclear plants will automatically shutdown itself, if the maintenance is going bad. It will automatically move all the nuclear fission material to a safe place and store it there forever. The "move" is by physics, not machines, so even with no power, the nuclear materials will be stored in safe containment. So relax. It's just TV drama.
