Dunkman Posted March 16, 2011 Share Posted March 16, 2011 Need to edit the description...I was thinking something like "It did. It can get pretty bad." I'm mostly joking...anyway, I haven't read this but it seems like a good timeline of events so far to catch people up who haven't been able to keep up with all the developments. http://www.reuters.com/article/2011/03/16/us-japan-quake-timeline-idUSTRE72F0WG20110316 Link to comment Share on other sites More sharing options...

LovintheWhiteFluff Posted March 16, 2011 Share Posted March 16, 2011 So is it officially a Level 7 on the nuclear disaster scale yet? Nope....Not enough radiation is being released into the atmosphere yet, but something tells me that haven't been getting too many readings lately near the reactors since it's been steady around 300 mSv to 400 mSv for a day with little reporting on any changes.

Dino Posted March 16, 2011 Share Posted March 16, 2011 I made a sample scenario for scale so people can relate better to the situation in Japan. I have placed circles increasing at 10 mile increments from the center which I have located at MD's Calvert Cliffs Nuclear Power Plant for a sense of realism.

JoMo Posted March 16, 2011 Share Posted March 16, 2011 Helicopter taking off with a water bucket on Japan television heading for the reactors. Guess a TEPCO conference is going on now. #2 reactor temps stabilized, pressure in core and container vessel has fallen. #4 situation not good #5,6 temps have risen. Really got to love TEPCO though. #2 reactor temps stabilized, or the gauge may be wrong. #2 reactor pressure in core and container vessel has fallen... this means it may be cooling.... or it may be breached.

Won't those be the concern in the coming days, as the reations in the plant stop? Or am I mis-interpreting what I have heard? Link to comment Share on other sites More sharing options...

OSUmetstud Posted March 16, 2011 Share Posted March 16, 2011 latest status table from TEPCO. Notice that the radiation at the perimeter is up to 3391 microSV/hr....or 3.391 mSV/hr. This is up 5-6 times since yesterday, but lower than the maximum of 12000 microSV/hr...12 mSV we saw the other day. Link to comment Share on other sites More sharing options...
SP Posted March 16, 2011 Share Posted March 16, 2011 Thanks OSU!.....here is a summary report Status of quake-stricken reactors at Fukushima nuclear power plants TOKYO, March 16, Kyodo The following is the known status as of Wednesday evening of each of the six reactors at the Fukushima No. 1 nuclear power plant and the four reactors at the Fukushima No. 2 plant, both in Fukushima Prefecture, which were crippled by Friday's magnitude 9.0 earthquake and the ensuing tsunami. Fukushima No. 1 plant -- Reactor No. 1 - Suspended after quake, cooling failure, partial melting of core, vapor vented, building damaged Saturday by hydrogen explosion, seawater being pumped in. -- Reactor No. 2 - Suspended after quake, cooling failure, seawater being pumped in, fuel rods fully exposed temporarily, vapor vented, building housing reactor damaged Monday by blast at reactor No. 3, damage to containment vessel on Tuesday, potential meltdown feared. -- Reactor No. 3 - Suspended after quake, cooling failure, partial melting of core feared, vapor vented, seawater being pumped in, building housing reactor damaged Monday by hydrogen explosion, high-level radiation measured nearby on Tuesday, plume of smoke observed Wednesday, damage to containment vessel likely. -- Reactor No. 4 - Under maintenance when quake struck, fire Tuesday possibly caused by hydrogen explosion at pool holding spent fuel rods, abnormal temperature rise in spent-fuel storage pool but water level not observed, fire observed Wednesday at building housing reactor, no water poured in to cool pool, spraying of boric acid being considered. -- Reactors No. 5, No. 6 - Under maintenance when quake struck, temperatures slightly rising in spent-fuel storage pools. Fukushima No. 2 plant -- Reactors No. 1, No. 2, No. 4 - Suspended after quake, cooling failure, then cold shutdown. -- Reactor No. 3 - Suspended after quake, cold shutdown. ==Kyodo Link to comment Share on other sites More sharing options...
SP Posted March 16, 2011 Share Posted March 16, 2011 reading through remarks etc....the white smoke from unit three is something that needs to be understood, or maybe they know. Notice post white smoke, the mention of containment vessel damage. I assume that is the steel vessel that would be rather difficult to damage, outside of a melt. My question for an expert would be, when containment vessel damage is likely, would that also indicate a meltdown has occurred and fuel coolant interaction has occurred, increasing the pressures and hydrogen levels which in turn caused the explosions at the reactors which likely have experienced a breach of the containment vessel? I am not sure if the containment vessel and reactor vessel are one in the same....perhaps the containment vessel surrounds the reactor? Link to comment Share on other sites More sharing options...
Ed Lizard Posted March 16, 2011 Share Posted March 16, 2011 http://users.rcn.com/jkimball.ma.ultranet/BiologyPages/R/Radiation.html 1000 mSv to cause illness, 4500 mSv about the 50% fatality does, so despite CNN suggesting these people remaining behind are risking death, it will take many hours of exposure even in the plant to risk radiation sickness. The 400 mSv noted for a time near reactor 3 in OSU's post is one notable exception, I'd hope workers minimized their time near there as 2 or 3 hours exposure would be enough to cause some illness.

Even so, they are still taking a significant risk to their lives by being so close to an uncontrolled situation and subjecting themselves to high levels of radiation that might cause health problems or premature death down the road.

They're measuring over 3000msv near the perimeter and the helicopter that was too dump water had to turn back because radiation levels were so high. Today to me is the critical day. It will either get much worse or will stabilize. At some point the slow motion wreck either gets reigned in or starts to snowball. Link to comment Share on other sites More sharing options...
OSUmetstud Posted March 16, 2011 Share Posted March 16, 2011 I found a risk calculator online...that if anyone had taken a 400 mSV dose...their lifetime cancer risk would increase by about 4%. Link to comment Share on other sites More sharing options...
Dunkman Posted March 16, 2011 Share Posted March 16, 2011 Some good news maybe from Kyodo: BREAKING NEWS: No major damage to No. 3 reactor containment vessel at Fukushima No. 1 Does make you wonder where those extremely high radiation levels were coming from though.

SP Posted March 16, 2011 Share Posted March 16, 2011 Reading through various articles etc.....one retired operator stated that one final measure is the ability to hook up a fire truck to pump water.....he stated this was on all Mark 1's in America.....and the two he worked at. If so.....I would think having a retired pump truck on site would be standard. He stated that cooling should be easy on the Mark 1's providing you pump water....... He concludes that there must have been damage to the (cant remember exact words) the circulation loop...and explosions damaged other reactors cooling loops. Otherwise hooking up a pumper..cranking it up would be a fine .....last measure and it would work. Link to comment Share on other sites More sharing options...

Poimen Posted March 16, 2011 Share Posted March 16, 2011 I had no idea Japan still had an Emperor. Anyhow, it seems we are sending some trucks to help. 7:55 a.m. ET Wednesday, 8:55 p.m. in Tokyo] Two U.S. military water trucks are being sent to help in cooling damaged reactors at the Fukushima Daiichi nuclear plant, the U.S. military says. The trucks will not be operated by U.S. military personnel, but by employees of Tokyo Electric Power Company, which operates the nuclear plant.
