There was a bit less people than before the disaster but still a decent number. On my way from Tokyo to there, I was surprised because the motorway was quite distorted because of the effect of the earthquake (kinda of wavy) and it was a bit shaky to drive on it.

Deep beneath Fukushima's crippled nuclear power station, a massive underground reservoir of contaminated water that began spilling from the plant's reactors after the 2011 earthquake and tsunami has been creeping slowly toward the Pacific. Now, 2 1/2 years later, experts fear it is about to reach the ocean and greatly worsen what is fast becoming a new crisis at Fukushima: the inability to contain vast quantities of radioactive water. The looming crisis is potentially far greater than the discovery earlier this week of a leak from a tank that stores contaminated water used to cool the reactor cores. That 300-ton (80,000-gallon) leak is the fifth and most serious from a tank since the March 2011 disaster, when three of the plant's reactors melted down after a huge earthquake and tsunami knocked out the plant's power and cooling functions. But experts believe the underground seepage from the reactor and turbine building area is much bigger and possibly more radioactive, confronting the plant's operator, Tokyo Electric Power Co., with an invisible, chronic problem and few viable solutions. Many also believe it is another example of how TEPCO has repeatedly failed to acknowledge problems that it could almost certainly have foreseen — and taken action to mitigate before they got out of control. It remains unclear what the impact of the contamination on the environment will be because the radioactivity will be diluted as it spreads farther into the sea. Most fishing in the area is already banned, but fishermen in nearby Iwaki City had been hoping to resume test catches next month following favorable sampling results. Those plans have been scrapped after news of the latest tank leak. "Nobody knows when this is going to end," said Masakazu Yabuki, a veteran fisherman in Iwaki, just south of the plant, where scientists say contaminants are carried by the current. "We've suspected (leaks into the ocean) from the beginning. ... TEPCO is making it very difficult for us to trust them." To keep the melted nuclear fuel from overheating, TEPCO has rigged a makeshift system of pipes and hoses to funnel water into the broken reactors. The radioactive water is then treated and stored in the aboveground tanks that have now developed leaks. But far more leaks into the reactor basements during the cooling process — then through cracks into the surrounding earth and groundwater. Source | ||

Radiation readings near a tank holding highly contaminated water at Japan's crippled Fukushima nuclear plant has spiked 18-fold, the plant's operator said Sunday, as the company and officials struggle to bring the crisis under control after more than two years. Radiation of 1,800 millisieverts per hour was detected near the bottom of one storage tank Saturday, Tokyo Electric Power Co. (TEPCO) said. An Aug. 22 reading measured radiation of 100 millisieverts per hour at the same tank. Japanese law has set an annual radiation exposure safety threshold of 50 millisieverts for nuclear plant workers during normal hours. Last month, TEPCO revealed that water was leaking from the tank. Japan's nuclear regulator later raised the severity of the leak from a level 1 "anomaly" to a level 3 "serious incident" on an international scale for radiation releases. Although no new leaks were found at the tank, a TEPCO spokesperson said another leak had been detected from a pipe connecting two other tanks nearby. "We have not confirmed fresh leakage from the tank and water levels inside the tank has not changed," the TEPCO spokesperson said. "We are investigating the cause." TEPCO said the radiation measured was beta rays, which would be easier to protect against than gamma rays. The TEPCO spokesman also said the higher level of radiation from the latest reading was partly because investigators had used a measuring instrument capable of registering greater amounts of radiation. Instruments used previously had only been capable of measuring radiation up to 100 millisieverts, but the new instruments were able to measure up to 10,000 millisieverts. Radiation of 230 millisieverts was detected from the new leak from the pipe connecting two nearby tanks, and a new measurement of 70 was taken from a separate storage tank. Source | ||

2 hours and you are already at LD 50/30. 4 hours and LD 100/14. And they don't even know why radiation levels are so high :S | ||

TOKYO, Sept 4 (Reuters) - Radiation readings around tanks holding contaminated water at the crippled Fukushima nuclear plant have spiked more than 20 percent to their highest level, Japan's nuclear regulator said, again raising questions about the clean-up of the worst atomic disaster in 27 years. Readings at the Fukushima Daiichi plant showed radiation as high as 2,200 millisieverts (mSv), the Nuclear Regulation Authority said, up from 1,800 mSv at the weekend. Exposure to radiation of those levels would be enough to kill an unprotected person within hours. Source | ||

1. 2 years on and it's not under control? -I realize that radiation does not dissipate so quickly, but when they say that fuel is 'hot' what does that mean? 2. how/why the tanks they put in are leaking? | ||

The fuel is hot because radioactive decay produces heat. That's why they keep filling the tanks with water, to keep the reactor material cool. If they let it heat up too much, it could melt through the tanks they've so far contained it in. | ||

The "fuel" is hot because of the radioactive decay. The Area is not save for humans to work in. So Tepco set up the tanks in a hurry, they are not well made and leak the cooling water in the ground, also there is water leaking beneath the reactor... Tepco still has not established a closed cooling circuit, and won´t be able without risking peoples lives. They would have to seal the ground and remove the reactor from the seaside and put a dome over it. Can´t do to expensive. Nuclear energy, hard to control. | ||

The reactor material is not in the tanks, it is still in the ruins and cannot be moved because it's impossible for humans or robots to get there (heat, radiation and rubble blocking the way). Also i think i've read that the cores of 1 or 2 reactors have melted into the ground, but so far luckily not deep enough to contaminate Tokio's ground water. The Tanks contain water that was used to cool the broken reactors and also water thats streaming into the ruins. | ||

Just as there are lots of different cars, some being safer than others, there are lots of ways to do nuclear power, and they aren't all dangerous. | ||

TOKYO - A senior official of the Tokyo Electric Power Co(TEPCO), operator of the crippled Fukushima Daiichi nuclear plant, said Friday that situation in the stricken plant was "out of control," according to local media. The remark was made by Kazuhiko Yamashita, who holds the executive-level title of fellow, at a meeting with Japanese opposition lawmakers in the city of Koriyama in Fukushima prefecture, said Japan's Kyodo News. His words came less than a week after Prime Minister Shinzo Abe assured the world at a meeting of the International Olympic Committee (IOC) at Argentina that the situation in the damaged nuclear plant is "under control." The IOC last week ruled out Madrid and Istanbul and chose Tokyo as the host of the 2020 Summer Games, despite the ongoing highly contaminated water leaks at the plant, which was fatally damaged in a quake-triggered tsunami in March 2011. Japan's Chief Cabinet Secretary Yoshihide Suga reiterated Friday that impacts of the toxic water leakage remain "inside the plant's port" that was enclosed by breakwaters, Kyodo quoted the top government spokesman as saying. Suga also said the remarks by Yamashita were made under "grill" by the opposition lawmakers during their meeting, according to Kyodo. The TEPCO recently admitted that highly toxic water leaked from the plant and into the adjacent Pacific Ocean at a rate of around 300 tons per day from makeshift storage tanks on the site. Furthermore, it said this week that there are possibly two leaks in tanks storing highly-radioactive water at the facility, with the second leak causing radiation levels to spike from 650 becquerels per liter found near the first leak, to 3,200 becquerels per liter of radioactive substances detected at a trench near the second leak.

They did build and run a LFTR back in the 50's, and it worked great. But the Airforce cut the funding, and the program died. The idea is still sound, and even if the US isn't the first to do it, it'll happen. China and India are both already looking at it. | ||
