Nuclear incident at Fukushima

Officials: Level 1 nuclear incident today at Fukushima plant — “Extremely high radiation levels” found leaking near Unit 4



19 August, 2013

NHK, Aug 19, 2013: [...] The officials said on Monday about 120 liters of highly-radioactive water had leaked from a tank near the number 4 reactor. They detected 100 millisieverts per hour of radiation on the surface of puddles near the tanks. The maximum annual exposure limit for nuclear plant workers is 50 millisieverts. [...] Officials from the Nuclear Regulation Authority assessed the problem as a level one incident on an 8-point international scale.


Kyodo News, Aug 19, 2013: Highly toxic puddles found near water tanks at Fukushima plant [...] extremely high radiation levels have been found [...] The NRA released a preliminary assessment of a level 1 incident on an eight-point international scale, defined as an “anomaly.” […]


AFP, Aug 19, 2013: [...] TEPCO denied that toxic water had flowed into the adjacent Pacific ocean, but the Nuclear Regulation Authority ordered the utility to study the possibility that it had escaped into the sea through nearby drains. The NRA released a preliminary assessment that the incident was a level one incident on an eight-point international scale […]




Fukushima may eclipse Chernobyl as the worst nuclear disaster in history


Two years after the Fukushima nuclear power plant meltdown, the disaster is still causing problems, and the Japanese government is looking at new ways to address the issue.


Fukushima may be eclipsing Chernobyl as the greatest nuclear disaster in history. Public sentiment appears to be against the continuing reliance on nuclear power in Japan, but the government has been slow to move in that direction.


Aileen Mioko Smith, the Director of Green Action, joined Senior Producer Kate Zickel to talk about the current state of affairs in Japan regarding the Fukushima clean up.

Tritium Measurement In Fukushima Bay Highest Ever As TEPCO Admits 40 Trillion Becquerels Have Spilled Into Pacific


19 August, 2013


Over the weekend we posted an in-depth narrative of what may happen in a theoretical worst case scenario in Fukushima, one in which the government continues to do nothing and pretends all is well, and where the end casualties are millions of innocent Japanese (and other) citizens, whose only crime is believing their government. Sadly, with every passing day the theoretical is becoming all too real, and moments ago reality struck again, when the Nikkei newspaper reported that readings of tritium in seawater taken from the bay near the crippled Fukushima nuclear plant has shown 4700 becquerels per liter.


This was the highest tritium level in the measurement history.









Tokyo Electric Power Company (TEPCO) has detected the highest radiation level in seawater collected in the harbor of the crippled nuclear plant in the past 15 days, Nikkei reports.
 
TEPCO said the highest radiation level was detected near reactor 1. Previous measurements showed tritium levels at 3800 becquerels per liter near reactor 1, and 2600 becquerels per liter near reactor 2. The concentration of tritium in the harbor’s seawater has been continuously rising since May, according to Nikkei. 
 
Also on Monday, a leak of highly contaminated water was discovered from a drain valve of a tank dike located on the premises of the nuclear plant, according to Fukushima’s operator responsible for the clean-up.
 
The level of radiation at the site was estimated at 100 millisieverts per hour, while the safe level of radiation is 1-13 millisieverts per year, according to ITAR-TASS news agency.  The plant’s operator is currently investigating reasons for the leak, TEPCO said in  statement.

We don't know if simply raising the "safety threshold" again will do it this time, but we do know that trillions of becquerels flowing into the Pacific is a lot to quite a lot:







Earlier, Tepco admitted that an estimated 20 to 40 trillion becquerels of tritium may have flowed into the Pacific Ocean since the nuclear disaster.


Tritium, which slowly but surely is making its way to the United States. But one can't blame TEPCO of doing nothing. Oh wait. One can.







Protective barriers installed to prevent the flow of toxic water into the ocean have failed to do so. The level of contaminated water has already risen to 60cm above the barriers, which has been a major cause of the daily leak of toxic substances, TEPCO admitted.
 
Japan’s Ministry of Industry recently estimated that around  300 tons of contaminated groundwater has been seeping into the Pacific Ocean on a daily basis. TEPCO has promised to reinforce protective shields to keep radioactive leaks at bay.

And if that fails, TEPCO will simply "freeze" the exploded nuclear reactor in an inverted igloo in its latest idiotic MacGuyverian contraption, one which unlike Hollywood, does not have a happy ending when everything goes up, quite literally, in radioactive smoke again.
