Fukushima Daiichi Still Releases 10 Million Becquerels Per Hour
TEPCO admitted today that the plant is still releasing 10 million becquerels per hour to the atmosphere. This is in addition to all the initial and over time releases from the early phases of the disaster. TEPCO also claimed that the incident during unit 3′s demolition only released one trillion becquerels, much lower that the 4 trillion becquerels release estimate for the incident compiled by researchers at Kyoto University who found the releases in the … Read entire article »

Fukushima: Unit 1 Cover Removal & Demolition Work To Begin Soon
TEPCO has announced their plan to remove the cover of unit 1 so that debris on the refueling floor can be cleaned off. This work will enable viewing of the spent fuel pool and the condition of the reactor well. The work has come under increased scrutiny after it was discovered that similar demolition work at unit 3 had caused contamination up to 50km from the plant due to the wind blowing radioactive building dust. TEPCO’s … Read entire article »

New Robot Inspection Of Fukushima Unit 1
Two robots, sponsored by IRID conducted an investigation of unit 1. The areas between the 2nd and 3rd floors have radiation levels too high for humans to enter for any extended period of time. Robots Rosemary and Sakura were sent in to do a coordinated inspection. Rosemary is equipped with a newer type of gamma camera to record radiation readings.

TEPCO Restarts Fukushima Unit 5 Pool Cooling Without Permanent Fix
TEPCO has announced they have restarted the cooling system for unit 5 just days after stopping it due to a valve body leak. TEPCO mentions in this handout of the restart but there is no permanent fix mentioned as being completed or proposed. Earlier reports said TEPCO would suspend the system until they could determine a permanent fix. Apparently some patch on a cracked valve is now considered a permanent fix.

Welded Water Tanks Installed At Fukushima Daiichi
Welded water tanks to replace the miles of leaking bolt together tanks at Fukushima Daiichi are being installed. The tanks are welded off site and shipped in by barge, ready to install. This allows workers to do the bulk of the work somewhere safe, leaving only the final move and installation to be done in the radioactive areas. This does make one wonder why TEPCO hadn’t thought of this themselves when the first tanks were … Read entire article »

New Strontium 90 Removal System To Be Installed At Fukushima Daiichi
Kurion will provide a truck back filter system to remove strontium 90 from contaminated water currently held in storage tanks at Fukushima Daiichi. Kurion, Toshiba and TEPCO have all been mum about the exact role the new filter system plays vs. the ALPS system that has been the main hope for decontaminating water. ALPS is also intended to remove strontium but also to remove a wider array of isotopes. The system should be on line at some … Read entire article »
