via Japan Times / April 12, 2014 / Tokyo Electric Power Co. said Friday that toxic water found to have leaked last August at one of the huge tanks at the accident-hit Fukushima No. 1 nuclear power plant was far more contaminated than initially announced. After recalculating the radiation level, Tepco said the water contained 280 million becquerels per liter of beta ray-emitting radioactive materials such as strontium-90, instead of … →
TEPCO released an interim report into the recent construction worker’s death at the plant. The report showed that the worker had been working in a small cave like area while jackhammering concrete overhead. This was under the overhang of the building foundation. This scenario would have been considered inappropriate under the worker safety rules in most developed countries.
The hole dug for access to this area of the foundation was held back with plywood and steel conduit poles. A steel excavation wall set is the norm most places. It appeared there also was no soil bracing under the building where the worker was conducting the work.
Former Fukushima Daiichi workers Happy & Sunny both expressed frustration with the long time it took between the incident and getting the worker to the emergency room of the nearest hospital in Iwaki. There is still only ground based ambulance service to the plant. This can …

DOE is planning the first reentry into the mine for April 1st.
“Tomorrow, personnel are scheduled to enter the WIPP underground to survey conditions for the first time since the February 14 radiological release. A team of eight radiological control, mine operations, and mine rescue experts will descend into the mine through the Salt Shaft to establish a safe base of operations and conduct radiation surveys to check for airborne contamination. If no contamination is detected, a second team of eight members will enter the underground to check conditions between the Salt Hoist and the Air Intake Shaft.
Multiple mine entries are necessary before the team accesses the waste disposal area where a continuous air monitor detected airborne contamination. Once they reach that point, the team will locate and isolate the source of the contamination.”

Report-backs on many events showing up now at http://fukushimathirdanniversaryevents.blogspot.com.

The Department of Energy doesn’t seem to be reassuring many people that it has everything under control following the radioactive leak at its Waste Isolation Pilot Plant (WIPP) three weeks ago.
But at a meeting last night near the WIPP site in Carlsbad, New Mexico, both local residents and officials expressed frustration with DOE and its either inability or reluctance to provide concrete information about what happened and what comes next.
“Nobody knows what the plans look like. Nobody knows what the agenda looks like. We just hear a lot of surmises about what might happen and what might not happen,” John Heaton, a former state representative and head of Mayor Dale Janway’s nuclear task force, told a panel of officials at the town hall.
A joint public meeting was held in Carlsbad NM today for the public to ask questions about the incident at WIPP. The meeting video is archived here.
- DOE cited a release level at the meeting but did not specify if it was for just the underground area, both areas or just the above ground area.
- DOE says 84 microcuries were released during the event. This converts to 3.108 MBq (megabecquerels) by a direct conversion using Wolfram Alpha.
There were extensive conversations at the meeting, attempting to explain the lengthy process undertaken to read monitoring post filters to determine isotope identification. While this is work that needs to be done to further confirm the nature of the release it is not the only available measure of said release. The fact that DOE gave the 84 microcuries release estimate shows why the excuse that they are unable to give the public any further data for at …
