With all off the backup systems working, a meltdown is nearly impossible. Japan is extremely unlucky as that quake and tsunami simotaniously wiped out every backup system they had.
Actually Come to think of it, Chernobyl failed somewhat in the same way. Not from a natural disaster but due to a power fluctuation that caused their plant and all the systems to shut down. The only difference between here and Chernobyl at this point is the fact that they got the rods back in the reactor allowing at least SOMETHING to be done.
Which is why they are now pumping seawater in as a last resort. The problem is that its possible the reaction is strong and throwing off enough heat that it may be steaming off the seawater before it even has a chance to do much of anything.
I personally think they should be entombing this thing now and taking a loss on the whole system rather than slamming it with seawater and boron and hoping for the best
Comparing the RBMK reactor at chernobyl to the LWR in japan is like comparing a shoebox to a modern day bank vault in terms of reliability, containment, and all other lines around structures and redundancies.
Chernobyl was still in operation 14 years after the incident.
Four hundred times more radioactive material was released than had been by the atomic bombing of Hiroshima. However, compared to the total amount released by nuclear weapons testing during the 1950s and 1960s, the Chernobyl disaster released 100 to 1000 times less radioactivity.
Nevada has seen higher levels higher than Chernobyl over the course of testing.
Oh without a doubt, but I’m just making the point that Chernobyl had “safeties” in place just like Japan did, there problem much like japan was an event that caused all of them to fail at once. Big difference being that Chernobyl was a technical problem that would probably not ever happen again.
No, the REAL big differences is that the RBMK reactor at chernobyl had barley a scrap of containment vessel around the reactor core, and that the design of an RBMK reactor and it’s functions puts it at FAR more risk when this sort of incident occurs. People who know little about nuclear reactors confuse shielding with contaiment. Sheilding is essentially the protective layer that retains neutrons amongst other radiactive particles and isotopes while the reactor is in thermal operation, while the contaiment is essentially a large steel and concrete vessel that surrounds the reactor completely in the event that an internal rupture of the core and shielding occurs. Chernobyl had no such containment on any of it’s 4 reactors. If fact a concrete and steel sarcophagus was built around the #4 reactor to contain the debris of the still exposed reactors(which has been degrading drastically FWIW). A majority of the explosion of chernobyl was from when the RBMK’s moderator was exposed to the atmosphere, where it instantly ignited and exploded. A proper containment vessel could have been flooded and likely prevented that from ever happening if one was in place at the time.
Chernobyl was copious amounts of human error and bad timing combined with poor reactor design and faulty safety features. The LWR in japan is far from that. Again still a HUGE issue, but it’s no chernobyl. There only major issue with flooding the reactor site is that IF the final external contaniment vessel does rupture, then there can be massive contamination to the sea water. As stated before, beyond worst case scenario.
Read up on the differences of RBMK and LWR’s. One of their biggest differences lies in how and what they use the cooling water for, and ultimately one of the biggest safety benefits of LWR’s
Well I do not know as much as you seem to in terms of the reactors technologies or Nuclear technologies in general, I was more or less just trying to point out that it is always possible for a failure to happen, as its happend in the past. Regardless of their “technologies” it takes one major fuckup and subsiqent failures to result in a catastrophic failure which has happend in both cases. Apparently its not as clear cut to compare as I tried to make it seem.
Adam how da fuck you hold all this knowledge in your head? :lol
lol, but I wouldn’t go as far as to say that. chuck norris is the man :lol
i dunno. I know a little about this stuff from my dad from when he worked at GE, was laid off during the strikes and worked at Knolls, then returned to GE. Plus a few friends he had at Knolls, plus retired military friends and family in the nuke field(FIL was a nuke on a particular sub for a long time). I love this shit
They will get this under control no doubt. The issue is as stated in the video, them getting water INTO the pv to cool it. Flooding the site simply keeps the cv from overheating and melting down if it ever got that far. Being a BWR type reactor(no internal closed loop cooling system/steam generator) there’s a better possibility to tap into the moderator/feed water supply which is used to both cool the reactor and slow down the netrons simultaneously.
Personally, I think this could have all been avoided had they attached the flux capacitor to the binary signaling lines, creating a super-capacitor capable of holding an infinite amount of energy. Therefore, the heat caused by the inadequate sub-cooling of the outer dam, could have been absorbed as energy into the super-capacitor.
This would cause the meltdown to never occur, also, the excess energy could be harnessed and used to transport people and non-biological elements, through time and space.
Why this has not been done, I don’t know. I am beginning to think conspiracy.
Another reactor at Japan’s Fukushima Daiichi nuclear plant has lost its cooling capabilities.
“Japanese officials have said that they are operating under the presumption that there may be a partial meltdown in the No. 3 and No. 1 nuclear reactors. Authorities have not yet been able to confirm a meltdown, because it is too hot inside the affected reactors to check.”
There is a viral video going around right now on youtube that has a constantly changing name because it keeps getting flagged of another 3rd explosion with who ever is speaking saying reactor 1 and 3 have indeed just had a meltdown. The explosion makes that second explosion look like nothing cause now the entire containment building is gone there is nothing left no frame or anything
I hate the internet for this shit its so hard to tell whats real and whats some asshole dumping a bunch of BS out there
