Thread is about the various issues surrounding Japan in the aftermath of the recent earthquake. Don't bring the shit side of the internet to the thread, and post with the realization that this thread is very important, and very real, to your fellow members. Do not post speculative and unconfirmed news you saw on TV or anywhere else. Generally the more dramatic it sounds the less likely it's true. | ||

The utility says it will conduct another test of the leaked water at the reactor's turbine building. The company said on Sunday evening that the data for iodine-134 announced earlier in the day was actually for another substance that has a longer half-life. The plant operator said earlier on Sunday that 2.9 billion becquerels per cubic centimeter had been detected in the leaked water. It said although the initial figure was wrong, the water still has a high level of radioactivity of 1,000 millisieverts per hour.

I don't know anything about Nuclear stuff, but that's the current report. The 10 million x Higher thing was misreporting. That's the actual figure. http://www.bbc.co.uk/news/world-asia-pacific-12875327 | ||

That's the actual figure. http://www.bbc.co.uk/news/world-asia-pacific-12875327 2Sv, 2000mSv or 2 hours of exposure, is enough to cause severe radiation poisoning. 4Sv is lethal if untreated. 8Sv is a death sentence. However this is just from the immediate aftereffects of a large dose. 100mSv, 0.1 Sv or 6 minutes of exposure, is enough to increase the likelihood of cancer notably. The likelihood of getting cancer from exposure grows very quickly after that. | ||

With hot nuclear fuel rods at the bottom of a pool it seems likely that this breach of containment might also go DOWN in addition to up. If that is the case it would be stupid to just put a lid on the whole thing while the radiation still seeps out down and into the surrounding area via any water which is in the earth below the plants. Sure there is bound to be a thick layer of concrete below, but even concrete does get damaged over time. The closeness to a large body of salt water makes it practically imperative to "fix the problem" because this kind of atmosphere will increase the speed of corrosion in most of the metals used there. Even reinforced concrete (I hopefully used the correct technical term) has iron in it which usually isnt rust-proof. Thus these parts will stop performing their job eventually - after not being maintained regularly due to high radiation levels - and the whole building might collapse. So they simply HAVE TO fix the cooling and eventually take out the fuel rods to check on the central pressure vessel. Just covering it up wont work for long due to the aggressive atmosphere (which is something that Chernobyl didnt have, so covering it up is much safer there). That is something we developed after being the designated central battlefield for a potential third wold war which would be fought with short range nuclear missiles and even nuclear artillery. In addition to that germany is densely populated and there is no room to maneuver in case anything goes wrong ... something I would think Japan has in common with us due to the mountainous nature of the land. Thus losing a "30 km radius area" around Fukushima would be quite a blow if it comes to that and it is another reason why they simply have to clean up and fix the power plants. There are some types of UHPC (Ultra-High Performance Concrete) mixes that are specifically designed to withstand erosion from salt..... And they do not rely on on steel to provide tensile and flexural strength (which is the entire point of reinforcing traditional concrete mixes). And there are specific admixtures that can be used to help prevent erosion due to salt water anyways. And although I've never actually looked into it, I'm sure there are admixtures which can be used to help against radiation as well. So, if it comes down to it, it will be possible to contain the reactor in a far better way than Chernobyl was contained. Hopefully they don't have to though, and can get it under control ASAP. But if it's at the point where spending 6 minutes will noticeably increase your cancer risk, and 8 hours is 100% lethal, then they've gotta hurry up..... All this while still dealing with soooooooo many other effects of the earthquake.  Poor Japan.Basically, if they absolutely have to | ||

That's the actual figure. http://www.bbc.co.uk/news/world-asia-pacific-12875327 "At the quake-hit Fukushima nuclear power plant, high radioactive density detected in 3 turbine buildings may further delay work to restore the cooling systems for the overheated fuel rods. Tokyo Electric Power Company says that on Sunday it detected 100,000 times the normal density of radioactive substances in the leaked water in the Number 2 reactor's turbine building at the Fukushima Daiichi nuclear power plant. The water surface had a high radiation level of more than 1,000 millisieverts per hour. In similar tests conducted earlier, about 10,000 times the normal radioactive density had been detected in the turbine buildings of the Number-1 and -3 rectors as well. The utility on Sunday revised an announcement made earlier in the same day that 10 million times the normal level had been detected in leaked water in the Number 2 reactor's turbine building. It said it previously made an erroneous calculation, prompting the Nuclear and Industrial Safety Agency to order it to review its assessment procedures. In order to resolve the problem of the contaminated water, the utility says it is trying to accelerate work at the Number-one reactor to pump the water from the basement into the turbine condenser for storage by increasing the number of pumps from one to 3. The company says although it had planned to take similar steps to remove the water from the Number-2 and -3 reactors, their turbine condensers were found to have been almost full and unable to contain any more water. The company says it is considering pumping that water from the condensers into adjacent pools and then filling them with the contaminated water. Regarding spent fuel rods in the storage pools, the company told reporters early Monday morning that the pools in the Number-2 and -4 reactors appear to be filled with water, with the rods submerged. The company said the pool's water temperature at the Number-2 reactor measured 56 degrees Celsius---a level slightly higher than usual--- at 5:50 PM on Sunday.

Does anyone have good links for news on the disaster? I check Reuters, BBC and Kyodo regularly but after Libya kicked off the international media has moved on and there simply isn't as much news and frequent updates as there was when the international media was staring down the necks of TEPCO and the govt here. | ||

This is very bad. Edit: Although the trench is not directly connected to the sea, there is still a fear that the water might leak to the sea. Edit 2: Kyodo news: "High levels of radiation exceeding 1,000 millisieverts per hour were found in water in a trench outside the No. 2 reactor's turbine building at the troubled nuclear power plant in Fukushima on Sunday afternoon, Tokyo Electric Power Co. said Monday. One end of the tunnel-like trench is located about 55 meters from the shore, with the surface of the water staying about 1 meter below its ground-level hole. But no trace has been confirmed of the contaminated water having flowed into the sea, an official of the company said. Similarly high levels of radioactivity have been found in a pool of water in the basement of the turbine building for the No. 2 reactor at the Fukushima Daiichi complex, raising concerns that radioactive substances may have seeped into the environment, including the sea nearby. The level of radiation at a similar trench for the No. 1 reactor was 0.4 millisievert per hour, the utility company said, adding that radiation could not be measured at a similar location for the No. 3 unit due to difficulty getting there." http://english.kyodonews.jp/news/2011/03/81532.html | ||

It could still all fail and there is still potential for re-criticality, as small a chance as that is, but here's hoping that doesn't come to pass. I mean when tepco accidentally told everyone that the radiation at certain places was 10 million times normal. | ||
