[Various] Japan Nuclear Emergency - Continuous Coverage of Damage and Radiation Risks - Page 270  

post #2691 of 2836
Hmm. TEPCO put out a rather interesting press release on the 20th:

Quote:
We deeply apologize for the anxiety and inconvenience caused to local residents near the site and broader society due to the accident at Fukushima Daiichi Nuclear Power Station caused by the Tohoku-Chihou-Taiheiyou-Oki Earthquake that occurred on March 11 2011. Today, we held a Board of Directors meeting where it was decided to decommission Units 1 to 4 and abolish plans to build Units 7 and 8 at Fukushima Daiichi Nuclear Power Station.

Fukushima Daiichi Nuclear Power Station was severely damaged due to the Tohoku-Chihou-Taiheiyou-Oki Earthquake and the tsunami that followed after. In particular, the melting of the fuel pellets inside Units 1 to 4 caused them significant damage. This was followed by a series of explosions. Hence, the decision to decommission them was made. Furthermore, in consideration of the societal impact, we believe that it would be very difficult to gain acceptance from local residents with regards to building additional Units 7 and 8 and therefore, decided to abolish their construction plans.

Power-grade uranium cannot explode. It's just impossible, because it's not enriched enough to have a quick enough and large enough chain reaction to cause an explosion. "

As soon as that thing pulsed on meltdown it set off everybody's satelites that are sensor packed for nuclear detection which is why they admitted it. Power grade uranium can explode. It is balanced for excess neutrons which are sucked up by the nickle control rods. You remove the control rods and it starts an explosion. It's a very very slow explosion and the core simply melts down before it reaches an explosion but some of the fuel will go off. If it's only a few atoms and results in 10 lb of tnt explosion then that's the end of the explosion. ALL the fuel won't explode because there's not enough excess neutrons to do it. 13 neutron pulses were created one of them hit other fuel and caused a small explosion relative to a nuclear bomb. It was rather large as these buildings are not cracker boxes. They are thick they are rough they are tough and it blew one of them to nearly shreds and put massive I beams in the fuel pool.

So you're sort of right. No a powerplant can't go full nuclear bomb explosive. But they can explode with rather frightening force.


The explosions that did physical damage to the plants were from hydrogen buildup, NOT from the nuclear material itself!

Again, I am not arguing that there are not small nuclear fission events happening, but it will never happen in a large enough sequence with power-grade fuel to cause any sort of large explosion or significant damage.

Reuters just reported Japan has just now confirmed 2 of the other suspected Reactors have gone Full Meltdown. They said this likely happened early on and they allude to them keeping it quiet to avoid additional panic in Tokyo in the early days of the disaster.

Idiots, everyone knew all 3 suspect Reactors were going to Meltdown.

Overall what a disaster.

LOL No. Yes you can have hydrogen build up but it was a nuclear explosion.
Right now they are fighting the core melt down with boron. It's not going too well. The thing just jumped up from 45ish seiverts to 200 plus. Boron should stop soaking up the excess neutrons before too much longer and it should melt down to water table and go critical scattering some 3 or so tons of gaseous plutonium and uranium all over. You just don't get it. Plutonium isn't uranium it's a built up uranium on steroids and it's got so many excess neutrons it just doesn't know what to do with em.

This isn't a hydrogen explosion.

This video is no longer available due to a copyright claim by Fukushima Central Television.

Interesting that the news can be copyrighted!!

It's not, huh? And what is your source? Where are you getting the information that ALL of the news sources are lying? Not only that, how did such an explosion happen without rupturing the containment vessel, where the nuclear material is stored?
