6/24/2011 | Levee Fails Upstream From Cooper Nuclear Station
Source: Nebraska.StatePaper.com
Date: 6/24/1970
Authorities: Don't worry
A levee three-miles upstream from the Cooper Nuclear Station at Brownville failed Thursday night, but authorities said the incident presented no threat to the nuclear plant. The failed levee, in Atchison County, Missouri, was breached at about 9 p.m.
Atchison County borders Nemaha and Otoe Counties in Nebraska. The Cooper plant, operated by the Nebraska Public Power District, is in Nemaha County.
An emergency evacuation was ordered for Atchison County west of I-29, including Landgdon, Watson, Phelps City, and Nishnabotna.
“This is a large breach and water will be moving rapidly. Persons should stay out of this area if previously evacuated due to danger,” the Atchison County Emergency Management office said in a prepared statement.

Date: Recording started June 24, 2011 12:41:53 AM CST
Per the Geiger counter's owner (CerebralProgrammer) 20 CPM (counts per minute) is the normal background radiation level. I first noticed an unusually high reading last night at about midnight CST. Tonight I have recorded a 2 minute or so sampling of high readings where 100 CPM is touched or exceeded, or 5x background.

6/24/2011 | Drone Aircraft At Fukushima Plant Loses Control, Lands On Reactor Building
Source: DOW JONES NEWSWIRES
Date: JUNE 24, 2011, 12:22 A.M. ET
by: Mitsuru Obe
TOKYO (Dow Jones)--A small 8.2 kilogram drone aircraft gathering data from heavily damaged areas of the Fukushima Daiichi nuclear power plant lost control Friday and landed on the roof of the No. 2 reactor building, plant operator Tokyo Electric Power Co. (9501.TO) said.
The vehicle, known as a T-Hawk, is about 20 centimeters in diameter and looks like a small jet pack. It is used primarily by the military for reconnaissance work in dangerous areas. It has been used at Fukushima Daiichi since mid-April to assist in damage assessment.
The company said there didn't appear to be any damage from the impact of the vehicle, with no fire or smoke observed following the accident. It wasn't known if the vehicle was damaged in any way.
Tepco spokesman Junichi Matsumoto said that due to its small size and weight, the drone is "unlikely to crash through the rooftop and damage the reactor."
Tepco said it may attempt to retrieve the unit using a long crane.
The No. 2 unit is the only one of the four reactors to retain its roof following explosions at units 1, 3 and 4 that destroyed much of their outer buildings.
Tepco is undertaking a nine-month project to bring the heavily damaged reactor units under control following the March 11 earthquake and tsunami.

6/23/2011 | TEPCO radioactive water treatment under-performance blamed on incorrectly set valve
Date: 6/23/2011
The Kurion (U.S. company) subsystem was tested to be only 10% as good at filtering radioactive material as expected during previous testing. TEPCO thinks it is due to the cesium filtration component which was installed with one valve incorrectly opened. Here is the English handout diagram given to reporters:
TEPCO will test the radioactive water treatment system with the valve closed.

6/22/2011 | TEPCO restarts Fukushima Daiichi water treatment but tests show underperformance
TEPCO has continued tested it's radioactive water treatment system at Fukushima Daiichi but discovered that the subsystems were not performing up to expectations. Per the EX-SKF blog expectations were for a 1/1,000,000 reduction in radioactive materials overall after filtering, but only a 1/18,400 decrease was actually achieved. The under-performance was noticed in the Kurion treatment subsystem, as well as the Areva (French) subsystem which both did not perform up to expectations.
The latest estimate for the amount of water pooled at the Fukushima Daiichi complex is estimated at more than 110,000 tons. Per TEPCO spokesman Junichi Matsumoto 1700 tons of water have been treated so far. The processing rate at which TEPCO wants to run the water treatment system is 50 tons/hour. Assuming 24 hour nonstop operation, 1200 tons/day of radioactive water could be theoretically processed at this rate. Approximately 500 tons a day of water is injected in to Fukushima Daiichi per the JAIF (Japan Atomic Industry Forum, Inc.) Earthquake Report for June 22, 2011.
In order to decrease the rate at which the radioactive water is building up TEPCO has reduced the amount of water being poured in to reactors 1 (-.5 tons/hr), 2 (-.5 tons/hr) and 3 (-1 tons/hour) while carefully monitoring the heat level of the reactors. The #3 reactor did experience a heat rise per TEPCO who are monitoring closely without increasing the water poured in to the reactor. The water flow in the #1 and #2 reactors will be reduced by another -.5 tons/hr.
The right sidebar of the EX-SKF blog shows the number of millimeters left to the top of the water ditches for reactors 2 and 3 if you are interested in imminent overflow.

6/23/2011 AST | Japan issues tsunami advisory after strong 6.7-magnitude quake
Source: NewsCore via thetelegraph.com.au
Date: June 23, 2011 8:21AM (Australia time)
A TSUNAMI advisory was issued for part of Japan's north-east coast after a 6.7-magnitude earthquake struck offshore this morning local time, the Japan Meteorological Agency said.
The meteorological agency said today the latest jolt hit at 6.51am (7.51am AEST) about 50km off the east coast of Miyako, Iwate prefecture, at a depth of 20km in the Pacific.
The north-east coast of Japan's main Honshu island was ravaged by a 9.0 magnitude quake and monster tsunami on March 11, which left more 23,000 people dead or missing.
The disasters also crippled the Fukushima Daiichi nuclear power plant, triggering the world's worst atomic accident since Chernobyl in 1986 and forcing hundreds of thousands of residents to leave their homes.
If there is a tsunami, its height is only expected to be around 1.6 feet (0.5m), and it would likely affect coastal regions of Iwate prefecture, the JMA said.
