RSVDon Posted March 11, 2011 Report Share Posted March 11, 2011 I'm surprised by a nuclear plant design that allows the boiling water being passed to the turbines to become even slightly radioactive. Aren't those typically in a separate closed loop system? Besides that, the pic looks like its right by the water, seems like they should be able to use pumps to get some cool water in there.It's not unheard of. Do you have info that this reactor is a boiling water type where the coolant steam is what turns the turbines? I didn't figure they'd use that setup. It's usually the radioactive coolant which is just circulated between the steam chamber and reactor rods, then a second coolant system is the one that gets boiled to create steam, to turn the turbines. If the system is the latter, there's always going to be one radioactive coolant and one not. Boiling of the radioactive one sucks. Hope that reactor case holds if it were to loose coolant and suffer a meltdown...Chernobyl's reactor did some crazy things with a 11 ft deep concrete slab over top of it....well, WAS over top of it.

Disclaimer Posted March 11, 2011 Report Share Posted March 11, 2011 Beyond the human suffering, this is related to the forum...How the earthquake is affecting Japan’s motorcycle companieshttp://hellforleathermagazine.com/2011/03/how-the-earthquake-is-affecting-japan%E2%80%99s-motorcycle-companies/This illustration shows the locations of Japanese motorcycle factories and companies in relation to the 8.9 magnitude earthquake’s epicenter off the coast of Sendai. So far, the only word of significant damage comes from Honda’s Tochigi R&D facility where one person was killed and 30 injured during the quake. It should be noted that this is an ongoing event, aftershocks continue and tsunami warning remain in place for the entirety of Japan’s east coast. Illustration: Grant Ray Even though most of the above facilities appear to have escaped the catastrophe unscathed, it seems reasonable to expect disruptions to production as Japan’s infrastructure reels from the massive quake. According to Jason Fullington’s firsthand report, public transportation in Tokyo is currently shut down completely and the roads — jammed with people trying to reach loved ones or escape damage — aren’t much better. The next few weeks are likely to see energy shortages, continuing difficulties with transportation and emergency measures which could further interrupt normal operations.

ReconRat Posted March 12, 2011 Report Share Posted March 12, 2011 In the past hour and a half there have been 7 more quakes. Is this area always this active?Yes, after a major event like this, there will be several days of settling down and adjusting along the fault line. Like they said, there was a 7.1 or something a couple of days before, and in 1 in 20 of those, it's a precursor to a "big one". This time it was.

ReconRat Posted March 12, 2011 Report Share Posted March 12, 2011 (edited) Ah, all reactors were successfully scrammed during the largest earthquake. No more reactions. That's good.Scrammed, yes, but still struggling to reduce the core temperatures. The power for the pumps of the cooling systems failed at most of the reactors. And the worst one just exploded the outer concrete containment shell.Watch the explosion here - CNNThere is no fear of a meltdown, since these are not fast breeder reactors like the one at Chernobyl. But they will have to cool them down and quickly. They have started pumping sea water into some of the buildings for cooling.And there has been a fair amount of radiation released to the local areas surrounding the worst of the reactors. One reactor now has cleared everyone out of a zone of 10 kilometers around it.edit: 83,000 people live within the 10kilometers around the two worst cases.edit: two reactors have cleared a 10k zone, and the one that exploded increased to 20k.

Cheech Posted March 12, 2011 Report Share Posted March 12, 2011 Ah, all reactors were successfully scrammed during the largest earthquake. No more reactions. That's good.There's a pretty active discussion on Fark about this, and from what I can gather these things are happening. Disclaimer: I'm not a nuclear scientist, merely a pudgy engaged observer. Consume the appropriate amount of salt.The reactor is a Boiled Water Reactor design, with a metal Reactor Vessel, a concrete containment chamber around that, and possibly a chamber around that designed so that weather events don't erode or compromise the containment chamber.From what I understand, they are still running on batteries (more which are being delivered) since the diesel generators were knocked out in the tsunami. Whatever power source they have (or don't), it's not enough to keep the pumps running continuously to circulate fresh water, hence the pressure buildup.Don's post is somewhat accurate in that they scrammed the reactors after/just before the quake, however that puts them out of OMGWTFBBQ CHERNOBYL! disaster range and more into Three Mile Island range. Reactors don't just shut off, the analogy I'm hearing thrown around the most is they are akin to a stove; you can kill the flame/element, but you'll still burn your hand if you touch the top. What we're seeing now is decay heat, which as long as they can keep that under control they should be out of the woods.Explosions are never good, and I don't know whether the outer shell of the containment structure blew or the containment structure itself. They are talking about releasing pressure (steam) to the atmosphere, the vents of which are filtered so the environmental fallout of the venting would be controlled.One last thing, try not to get too caught up with the media talking about 100x levels this or 1000x levels that. Radiation is measured using a logarithmic, not exponential scale, I'll let some of the mathletes here explain that in further detail.

ReconRat Posted March 12, 2011 Report Share Posted March 12, 2011 (edited) The explosion was from a build up of hydrogen gas. The zone around that one has been increased to 20 kilometers....Japan's nuclear agency said there was a strong possibility that the radioactive cesium the monitors detected was from the melting of a fuel rod at the plant, adding that engineers were continuing to cool the fuel rods by pumping water around them. Cesium is a byproduct of the nuclear fission process that occurs in nuclear plants. Before Edano's announcement, Malcolm Grimston, associate fellow for energy, environment and development at London's Chatham House, said the explosion indicated that "it's clearly a serious situation, but that in itself does not necessarily mean major (nuclear) contamination." "This is a situation that has the potential for a nuclear catastrophe. It's basically a race against time, because what has happened is that plant operators have not been able to cool down the core of at least two reactors," said Robert Alvarez, a senior scholar at the Institute for Policy Studies in Washington...http://www.cnn.com/2011/WORLD/asiapcf/03/12/japan.nuclear/ Edited March 12, 2011 by ReconRat Quote Link to comment Share on other sites More sharing options...

ReconRat Posted March 12, 2011 Report Share Posted March 12, 2011 (edited) Good BBC videos of the explosion and results, on the AlJezeera English channel: edit: Containment pressures are out of control at seven reactors at two locations now. They will begin venting radioactive gas and steam to try and lower the pressures. Monitoring of radiation levels outside the facilities show Cesium, which means that some of the fuel rods are melting. The reason that is bad, is that the fuel rods wind up as a puddle at the bottom. Then there is no control of the nuclear reaction. The result is a continuous build up of heat, until it is hot enough to melt through the bottom of the reactor and into the ground below.
