re. Reactor buildings covers: I can't find the link now but I read recently about the plan to cover all reactors 1, 3 and 4 with a temporary cover and later on they will install a more robust cover which they usually use every time they do inspections or refuelling operations where it is required to remove the top head of the RPV and expose the fuel. The plan might be on TEPCO's English version website, IAEA website or JAIF website. I'm not sure.

Hmmm from this pdf www.meti.go.jp 3.4 times the amount of xenon-133 was released from the 4 units, as all noble gases were released from Chernobyl, according to UNSCEAR. This is without krypton.

i am getting confused if this is news or olds:

TEPCO forced to halt water treatment system again
22:26
TOKYO, June 29, Kyodo english.kyodonews.jp

seems NEWS ...

Awesome -- insert radioactive waste, it comes out smelling like roses :)

maybe this is a time warp.

Whoops, you blinked -- they stopped it again.

do
filter
sleep
leak
loop

Here's the report on the accumulated water treatment and treated water injection time line according to TEPCO's latest report:

"- From 8:00 pm on June17, we started operation of water treatment of
accumulated water at accumulated water treatment facility.
- At 9:56 am on June 22, we started transferring accumulated water in
turbine building of Unit 2 to central waste treatment facility building.
- At 4:20 pm on June 27, the operation of circulation injection cooling
was initiated by injecting water from the filter water tank as well as
usage of the treated water regarding water injection to the reactor. At
5:55 pm, since we confirmed a leakage from the pipe which supplies water
from treated water tank to injection pump of reactor, we stopped
supplying treated water. Subsequently, we have implemented measures
against the leakage at pipe joint. At 2:36 pm on June 28, we started
operation of supply pump for treated water, and resumed the operation of
circulation injection cooling at 3:55 pm.
- At around 3:00 pm on June 28, water blot was confirmed at the outlet
flange of the processing transfer pump of the accumulated water
treatment system, and a saucer was installed at 3:45 pm. After that, no
increase of the blot has been confirmed.
- At 8:10 am on June 29, (two) minute holes were confirmed at the hose for
the injection cooling system of the accumulated water treatment system,
and we temporally repaired them. At 10:59 am, we replaced the pipe with
a new one while operation of the processing transfer pump was suspended.
We started to operate circulating injection cooling at 1:33 pm.
- At around 9:30 am on June 29, water leakage was confirmed at the drain
of lower part of the primary storage tank for water desalinations
reverse osmosis membrane concentrated water in the accumulated water
treatment system. We stopped the leakage by installing a drain cap at
10:30 am.
- Since an alarm showing water leakage was sounded in the On-site Bunker
Building at 2:49 pm, the accumulated water treatment system was stopped
at 2:53 pm.
- From 9:40 am to 3:29 pm on June 28, we injected fresh water to the
reactor well (unit 4) and temporally dry separation pool for environment
improvement (reduce radio active dose) on 5th floor reactor building of
unit 4." www.tepco.co.jp

If you read the rest of the report you'll find two more incidents that apparently haven't been reported on the news yet.

@bojack54 I read that the dry cask storage facility is underground. I'm not familiar with Calhoun's plant design so I can't be of much more help there.

Shareholders reject anti-nuclear proposals at Japanese utilities

OSAKA, June 29, Kyodo

Shareholders rejected anti-nuclear proposals at the annual general meetings of three Japanese power utilities Wednesday following a similar development at Tokyo Electric Power Co. on Tuesday.

Some shareholders called for withdrawing from nuclear power generation in meetings for Kansai Electric Power Co., Tohoku Electric Power Co. and Chugoku Electric Power Co. amid heightened safety concerns following the Fukushima nuclear crisis, triggered by the March 11 quake and tsunami.

Their management leaders defended their nuclear power generation plans with anti-nuclear proposals voted down at their longest-ever shareholders' meetings.

About 90 more homes to be encouraged to evacuate

About 90 more households around the Fukushima Daiichi nuclear plant are likely to be urged to evacuate due to high radiation levels in their areas.

The houses are in 3 districts in Date City not designated as evacuation zones but in areas where accumulated levels of radiation are expected to exceed the threshold of 20 millisieverts a year. Date is about 60 kilometers from the troubled plant.

The government is to consider designating which houses in these districts will need to be evacuated depending on local radiation levels.

Designated residents will receive state support for relocating, including the provision of substitute homes.

On Tuesday night, officials explained the evacuation system to about 400 residents.

One resident asked whether households not recommended to evacuate will receive any public support. Another asked why there is no need for everyone in the districts to evacuate.

A 21-year-old mother said she feels the designation system is unfair, adding that she is full of anxiety about the possible impact of radiation on her child.

"encouraged to evacuate" ?

sounds like : it is better for you to move away, but we will not pay.

TEPCO restarts new cooling system
The operator of the Fukushima Daiichi nuclear power plant restarted its new reactor cooling system on Wednesday after fixing faults in the hosing.

Tokyo Electric Power Company was forced to suspend the system's operation earlier in the day after plant workers detected water leaking from 2 holes in the hosing.

On Monday, TEPCO halted the system after 90 minutes of operation due to water leakage from a displaced joint connecting plastic hoses.

The system was restarted on Tuesday afternoon, but more leaks from another joint were found.

After the series of leaks, TEPCO says it will look at ways to strengthen the system's hosing.

Also on Wednesday, workers found water leaking from a storage tank for decontaminated water. www3.nhk.or.jp Morning all! Found this just now, but probably old already!!

@LM : no, this is old. it is halted again. english.kyodonews.jp 22:25

@Edano Oh well..it figures!

imagine they run out of duct tape ...

@Edano That would be catastrophic.
