The Fukushima #1 meltdown was man-made, namely the absolute ineptitude of the Japanese government at the time. As disasterous as the 3/11 earthquake and tsunami were, those were not what ultimately caused the meltdown.
When faced with pressure to save money but still deliver, weighed up against a very low risk of catastrophe in their time, they did the mental math and cut corners, found ways around the safeguarding policies previously put in place and kicked infrastructure spending down the line.
The big problem with nuclear is not technological, it’s guaranteeing that whoever is responsible for it will be competent, capable and solvent for hundreds of years.
When the tsunami hit and Fukushima #1 lost power and was at risk of meltdown, TEPCO was ready to scuttle the reactors by dumping seawater in them. It would have rendered the reactors unusable, but meltdown would be prevented.
The Japanese government at the time, coming from the Prime Minister (Naoto Kan) himself, denied TEPCO from scuttling them because the government wanted the reactors usable. TEPCO was begging for authorization but it was not meant to be.
So what happened was the meltdown happened and the reactors became unusable anyway.
The blame was then scapegoated on TEPCO, because elite politicians surely can't and shouldn't be prosecuted for their ineptitude.
What happened at Fukushima #1 was a human failure that did not have to happen.
Bittersweet revenge was that the incumbent party at that time, the Democrat Party of Japan, lost the subsequent general election and the party subsequently fell apart.
The nuclear (TEPCO) people in the field were and are amazing, and it is a cardinal sin they got scapegoated for political purposes.
"Everything would have been fine if it weren't for the politicians" is not a path forward. These sorts of disasters will continue to happen.
Isn't it always true, for such matters?
As we cannot avoid committing errors it seems better to prefer a way without any risk of major accident (very dangerous radioactive things, difficult to cleanup, travelling long-distance thanks to wind, rain...). No wonder renewable sources quickly gain traction.
That isn't how this works.
We have a replacement for nuclear: renewables.
Renewables can be a complement to other power sources, but to even suggest they can be a "replacement" for nuclear power indicates either naivety or ignorance.
As I said: "The big problem with nuclear is not technological, it’s guaranteeing that whoever is responsible for it will be competent, capable and solvent for hundreds of years."
Humans working in the nuclear industry are "the" nuclear industry. By definition all economical sectors are arranged around human workers. Remove each human and the industry will lose its reason to exist.
I mean. If the story is true (which I have my doubts about). Then the simple change required would have been to make it clear that TEPCO has the sole authority to decide to scuttle the reactors. The politicians could have been morons going on a power trip all they wanted, and the reactors would have been safely scuttled.
If you are a firefighter you wouldn't ask the government if you should pump gasoline or water on a fire. Why did the people managing the nuclear reactors gave the government an opportunity to choose wrong? (Or rather, why was the system set up such that it was not already clearly defined under which technical circumstances the reactor must be be scuttled.)
For the simple reason that the 3/11 Tohoku Earthquake defied and rewrote essentially all the geological/maritime scientific and political expectations up to that point.
I doubt the same errors will happen today, but hindsight is 20/20.
Don't worry, experts are perfectly able to maintain a high level of safety (nope), then to assess correctly during an accident (nope: https://www.scientificamerican.com/article/nuclear-power-ody... ), and also to manage the aftermath (nope... https://www.scientificamerican.com/article/special-report-he... ).
PM Naoto Kan infamously declared "I know nuclear!" in unilaterally ordering TEPCO around during the crisis and ultimately denying their request to scuttle the reactors. Nevermind that TEPCO had the finest nuclear engineers Japan could muster at that moment.
For his valiant achievement of causing a nuclear meltdown and turning back the clock on nuclear power for the better part of a century, PM Naoto Kan was rewarded with merely the loss of his premiership, loss of his parliament seat in the subsequent general election (regained in the same election by proportional vote), and the victim card (sympathy from guys like you).
TEPCO's engineers meanwhile got dragged through the judicial mud before they were finally cleared a few years ago, the train to repair their reputation having left the station long ago.
A solid source detailing the story would be useful.
TEPCO ignored his order to stop pumping in order to avoid re-criticality, and Kan soon accepted TEPCO views on the matter: This seems sourced to me (no mention of scuttling anything): https://en.wikipedia.org/wiki/Naoto_Kan#Fukushima_nuclear_ac...

I don't think so. Japan was, then, in a political turmoil with 4 prime ministers from September 2006 to June 2010 (when his mandate began): https://en.wikipedia.org/wiki/List_of_prime_ministers_of_Jap...
He passed a bill to promote the use renewable energy. This is sufficient, even for this ex nuclear enthusiast, to be blacklisted and villified.
