7,500,000 Bq/m3 of “Strontium-90″ was measured from groundwater. The sampling date was 9/11/2013. They haven’t announced it for 3 months.
The location is in the seaside of reactor1. Tepco has been analyzing the groundwater around the reactor buildings. This November, Tepco confirmed reactor1 directly leaking the coolant water out of the vessel. (cf, Leaking part of reactor1 is made of “poly vinyl chloride” [URL])
The crippled sand cushion drain pipe is made of poly vinyl chloride, according to Tepco. In reactor1, 2 parts on the pipe are broken and leaking the coolant water. The pipe is situated on the bottom of reactor1. In the press conference of 11/15/2013, Tepco stated the part doesn’t need to be strong in the normal operation. They still inject 4.4 tonnes of coolant water into reactor1 per hour. The same volume of water is leaking out from those crippled pipes.

Study on IAEA website: Core meltdown risk now around 1,000% higher because of Fukushima — Engineer: Nuclear disaster “a certainty” over next 30 years in Europe
Fukushima continues to spew out radiation. The quantities seem to be rising, as do the impacts. The site has been infiltrated by organized crime. There are horrifying signs of ecological disaster in the Pacific and human health impacts in the U.S.... Prime Minister Shinzo Abe has been leading Japan in an increasingly militaristic direction. Tensions have increased with China. Massive demonstrations have been renounced with talk of “treason.” ... But Tepco has clamped down on media coverage and complains about news helicopters filming the fuel rod removal. By all accounts, whatever clean-up is possible will span decades.
The town of Fairfax, CA, has now called for a global takeover at Fukushima. More than 150,000 signees have asked the UN for such intervention. Thousands of tons of radioactive water now sit in leaky tanks built by temporary workers who warn of their shoddy construction. They are sure to collapse with a strong earthquake. Tepco says it may just dump the excess water into the Pacific anyway. Nuclear expert Arjun Makhijani has advocated the water be stored in supertankers until it can be treated, but the suggestion has been ignored.
Hundreds of tons of water also flow daily from the mountains through the contaminated site and into the Pacific. Nuclear engineer Arnie Gundersen long ago asked Tepco to dig a trench filled with absorbents to divert that flow. But he was told that would cost too much money.

Highest radiation levels measured outside reactor
Tokyo Electric Power Company says radiation levels are extremely high in an area near a ventilation pipe at the crippled Fukushima Daiichi nuclear power plant.
TEPCO found radiation of 25 sieverts an hour on a duct, which connects reactor buildings and the 120-meter-tall ventilation pipe.
The estimated radiation level is the highest ever detected outside reactor buildings. People exposed to this level of radiation would die within 20 minutes.
The exhaust pipe in question was used to release radioactive gases following the outbreak of the accident 2 years ago.
TEPCO says radioactive substances could remain inside the pipes.

Unit 3: No Water Spray on Core Since December 9
This is interesting....
On December 9th they stopped all water injection on Unit 3 core:
www.tepco.co.jp...
They had been dumping 3.3 cubic meters per hour on the core...

No temperature changes noted whatsoever:
