Fukushima nuclear disaster re-created - Bang Goes The Theory - BBC 

i think there is some styrofoam in the rubble

Well your eyes are not great but not terrible .

Just shut up.

Oh you funnyboi

Hell No Reactor Dome...We won't Take Yer Styrofoam!!! . Don't by Walmart Reactor Domes!!!

You are, actually, if it was the same as all the rest the explosion could transfer its energy to the core and damage it. Fukushima had blast walls for a reason.

It's used so that the thing won't become a huge ass pipe bomb

When that pressure is in there, it has to goes out, the more you contend it, the more it became powerful. Not even a science fan, i may be wrong but i wonder if the explosion could have been avoided if they have built the top of the reactor with the same containment mesures they used for the rest of the plant.

You can have a small supercritical event though

@@aorusaki with proper mass, purity and reflector or neutron source. in reactor i think the fuel is not concentrated enough

I'd say good old aluminium. He added hydrochloric acid to it.

The reactor didn't explode, if you look at the containment buildings only the roof was destroyed which means the spent fuel pools ignited the hydrogen which seeped into the containment buildings, If the reactors exploded then the ENTIRE BUILDING would Be a burning wreck instead of the roof being a burning wreck.

If your stating that MOX fuel had something to do with the explosion being more powerful, then your wrong, The enrichment levels for the fuel used is not enough to make the fuel explode like a bomb, and an atomic bomb relies on a runaway reaction, A reactor Can not and Is unable to explode like an atomic bomb.

Fish Gil four words. Positive Steam Void Coefficient

That was a partial meltdown, not an accident including four reactor meltdowns and 3 of the containment buildings being damaged from a hydrogen explosion in the spent fuel area above the reactors.

Also let's not forget that had the back up generators been placed in a better location, such as on a higher floor other than a basement or first floor. Things could have been drastically different. The reason the back up generators were not available was because they had been installed in the basement of the building which was flooded by the tsunami.

Location near "tsunaming" ocean + Electric stuff in a floodable basement = Extremely dumb idea = Broken by design. qed.

JAPAN IS INTENTIONALLY HIDING AND PLAYING WITH THE REAL DATA CONCERNING CHILD THYROID CNCER INCIDENCE >2011 IN FACT , THEY ARE ROUTINELY REMOVING EVIDENCE (THYROID GLANDS) IN CHILDREN- NO INVESTIGATION-NO ULTEASOUND-NO BIOPSY. PURE EVIL ALL TO SPREAD GOOD NEWS PRIOR TO 2020 GAMES / PRESERVE RICE EXPORTS/ CAR EXPORTS/ PRESERVE NUCLEAR CRIME FAMILY. THEY ARE POISONING US ALL. DOES ANYONE ACTUALLY THINK THAT THIS ISN'T HAPPENING? HAS PHONE APPS REALLY BRAINWASHED US INTO BELIEVING EVERYTHING " THE APP " SAYS. WHY ARE PACIFIC ORCAS DISSAPEARING- FAST? ORCAS EAT CHINOOK SALMON? SALMON EAT SARDINES? SEA BIRDS EAT SEA CREATURES AND SMALL FISH... OH , ITS ONLY CLIMATE CHANGE= ANOTHER G7 MEETING IN AUSTRIAN ALPS- W/HOOKERS AND CAVIAR- YOU PAY(TAXES) THE FROGS HAVE BEEN BOILED NICELY. -ONTO TO FUSION REACOR TECHNOLGY NOW...... WHATTTTTT, WHAAAA. WHATS THE COSTS INVOLVED ?.....WHAAAAAAAT? NUCLEAR INDUSTRY HAS THE ANSWER! YOU PAY UP FRONT - FOR THE CONCEPT REALISATION ! YOU DONT BELIEVE ME? DO THE RESEARCH THEY WANT US TO PAY FOR THE FUNDING OF FUTURE REACTORS (YEARS IN ADVANCE) THIS GENERATION IS SO DUMBED DOWN , ITS NOT FUNNY. LETS LEGALISE CANNABIS (TO FURHTER ERADICATE CRITICAL THINKING ) YOUV'E BEEN BOILED NICELY. KEEP YOUR EYE ON THE PACIFIC ORCA SALMON NUMBERS .

@@user-gf6yl8jg6z Ok how many deaths has nuclear caused compared to fossil fuel deaths. There has been 1 direct death from the Fukushima nuclear accident. 800 deaths from stress in the elderly, the stress was caused by the evacuation. There has been 34 direct deaths from Chernobyl. 30,000+ people may die from cancer after Chernobyl No single death from Three Mile Island. The Windscale Fire had no direct deaths, and a few hundred to a thousand people may have died from cancers from before and after the Windscale Fire. SL-1 Nuclear Accident only 3 direct deaths caused by the reactor meltdown and no indirect deaths as the containment building was not destroyed. Fresh nuclear Fuel is barely radioactive so you can hold fresh uranium without protection. Uranium mining and Processing has caused few deaths in the range of 1000 deaths. Nuclear Fusion is not available yet, no not because of the costs, but because we haven't created a sustained Fusion reaction that actually produces more energy than we put in.

Reactor grade uranium isn't weapons grade (unless it's in a military vessel or headed to space), and fuel reprocessing to get plutonium is also difficult. Even if you have plutonium, it's difficult to make a nuclear bomb out of it (and a fizzle is pretty much a dirty bomb with more explosive force and less fallout). A dirty bomb made of the stuff we use for medical, industrial, and imaging purposes would be much easier to acquire, and has excellent optics for a terror group. If you have the resources to make a plutonium nuke, you can probably build a secret reactor to make the plutonium, and centrifuges to enrich uranium.

It was a plume of smoke, then nothing NOT A MUSHROOM CLOUD

Short answer: Yes.

Boiling? You mean, scientists have built a huge and complex reactor just able to power a turbine and with just a little debris of it the whole ocean boils? WTF where did leave logic?

+DiaveD I don't think logic was ever in them.

The amount of fuel in Fukushima would dilute in the ocean, even then the Japanese Clean up teams are clearing up Fukushima as we speak and all the radioactive materials will be stored in a safe storage facility.

+ zerpBot, in Fukushima, they managed to avert the reactor exploding by venting the gases from the reactor into the atmosphere, carrying with them a large degree of radioactive pollutants. In Chernobyl, the reactor did explode, and the actual graphite and uranium was ejected both in large chunks (on the roof and Elephant's foot) and in small ones (the smoke from the fires). So while you can say that Fukushima was just a slow Chernobyl, the speed of the Chernobyl accident meant that a plethora of other problems occurred, and it was qualitatively different from Fukushima.

Of course, they are two separate incidents but I believe I was thinking more about the amount of contamination when I made that comment. Yes, atmosphere vs sea contamination are very different.

Nope they were slightly different. Chernobyl's reactor number 4 was not shut down and destroyed the control rods leading to a complete meltdown. Fukushima's reactors were shut down and the control rods were inserted. But due to the water pumps failing the fuel wasn't cooled causing a meltdown.

@@zer0b0t Fukushima never exposed the core vs Chernobyl launching its core all over the goddamn place! There is a drastic drastic drastic difference between the two and one is far easier to control. Almost all the problems from Fukushima at this point originates with reactor three in the fact that the donut shape cooling pool below the reactor is what exploded not the roof like which happened in 1 2 and 4 and is demonstrated in this video. When they tried to vent the gas as he showed in this video that venting wasn't directly out of the core to the roof but in fact down into that cooling pool and it was from those cooling pools that they eventually vented the gas into the roof unfortunately reactor threes coolant pools valve did not open correctly and the cooling pool over pressurized and exploded launching not only radioactive gas but massive amounts of radioactive water directly from the core.

Chernobyl was cased by a completely different chain of events, the operators at Chernobyl didn't know that the reactor was unstable until the power surged

No, the core and containment of Chernobyl exploded, Fukushima the core melted and is in the containment which is intact but there was a hydrogen explosion in the building

do you? don't answer that because we both know your going to go to google, search it up and copy and paste the answer. that's not knowing it.

This isn't Propaganda, its and abridged and easily understandable version of what happened when the spent fuel ignited the hydrogen in the Top part of the containment buildings.
