Because that would make it even more complex to maintain. This reactor is a 40 years old design. Modern reactor designs can cool the residual heat without needing active cooling systems, so what we're seeing is a problem that has already been solved on any reactor that's built now.
The backup generators were underground actually and apparently died when the circuitry was flooded. What I don't know is, could the underground area be sealed off at all, even if it could you'd assume its normal operation after the earthquake would have opened them up.
I guess future design improvements that could have probably prevented the accident could be as simple as a huge chimney stack sticking out of the Turbine buildings(I'm under the impression the generators were beneath the turbine buildings) so they can get air to run/cool/etc but the building is essentially sealed up to roof level to prevent flooding.
I really haven't seen much on passive cooling, always better to have more redundancy but I'm assuming theres still ways passive cooling(I assume based on large surface area's and some airflow?) can fail, buildings getting some damage and holes getting blocked, various reasons decay heat doesn't fall fast or in the case of burning rods or coolant leak, increases, what level is passive cooling able to actually cool.
Realistically accidents will continue to happen even in the best designed plants, and then, we'll learn and make better plants.
I think one of the biggest dangers is unlike so many other industries, someone makes a fatal flaw in a car, its replaced in a year and maybe fixable on the go, nuclear power plants are designed to go for decades, are very expensive to build, expensive to close, and expensive to clean up so even if someone designed a supposedly fool proof design tomorrow, 99% of world nuclear power would be pretty old and more vunerable designs.
Like I've said, we should be aware of the risks but the alternatives are in my opinion, much worse, eventually running out of power, society without real levels of power, its almost unthinkable.
They are only making money off peoples irrational fear. It's not as though they are selling essential goods.
Yeah, I posted a quoted story, rather than like in the UK/USA where a bottle of water at a local store would have cost £5, some guy overcharged him for fruit, got on his bike, caught him at the station and gave him the right change.
This is basically what the pharmaceutical industry is based on. Selling drugs for hundreds of pounds when you can make them for a few quid.
Iodine tablets are pretty much useless anyway.
Throat cancer is pretty "easy" to get when Iodine 131 is lurking about and its made in pretty large quantities when the nuclear reaction is going(and fast decaying when not) and iodine tablets are actually a VERY effective way to prevent thyroid cancers. Though, Thyroid cancer is almost completely survivable these days, better to not have to go through treatment if you don't want to. Also companies make pretty huge profits, but not always disgusting when you realise how big they are. They pump SO much money into research , often on research that goes no where, if there weren't large profits available, they wouldn't put so much money into research for treatments for rare cancers and the like.
Its capitalism, nothing "good" gets done unless their profit in it
