6/16/2011 | Fukushima Daiichi reactor 1 dry well radiation dose at new highs (263 Sieverts/hour))

There is a new record high in the reactor 1 data set of 263 Sieverts/hour.  The old record high was 261 Sieverts/hour.  It seems like when the radiation dosage of the dry well gets high, they manage to get the radiation down at which point the radiation spikes again.  The chart looks like a sloppy Sine wave.

6/16/2011 JST | TEPCO tests treatment system for radioactive water

TOKYO — Workers at the stricken Fukushima Daiichi nuclear plant on Wednesday tested a treatment system for highly-radioactive water now kept in temporary storage that may overflow within days. The idea is to decontaminate the water and eventually reuse it as core coolant. Following a final test, the system is set to enter full operation Friday.

The March 11 disaster knocked out power and crucial cooling systems at the Fukushima plant, melting fuel in three reactors and leaking massive radiation into the environment.

Some radioactive water was released from the plant into the ocean, causing concerns about contamination of seafood.

The leakage stopped after the plant operator sealed cracks, built oil fences around the plant and took other steps.

OSAKA — The crisis at the Fukushima No. 1 nuclear plant has heightened concern in the Kansai region, where 15 atomic reactors are located less than 55 km from Japan's largest freshwater lake, a source of water for millions of people in Kyoto and Osaka.
The fears and questions being raised about the effects of a nuclear accident at one of the Fukui Prefecture plants has spurred local governors to review their disaster plans.

All of Kansai's nuclear power is generated by reactors on the Sea of Japan coast in Fukui.

The operator of the Fukushima Dai-Ichi nuclear plant has announced plans to construct a shroud over one of the reactor buildings, a stop-gap measure until a more permanent solution can be found, such as entombing the facility in concrete.
