Fukushima Refueling Machine Portion Falls In Spent Fuel Pool

Fukushima Refueling Machine Portion Falls In Spent Fuel Pool

TEPCO is reporting that the console portion of the refueling machine that fell into the spent fuel pool of unit 3 during the initial explosion has now fallen further into the pool. Workers were attempting to remove the section of the refueling machine from the pool when it broke loose and fell into the pool. TEPCO thinks it fell into a section of the pool beside the fuel racks but will be doing an underwater camera inspection … Read entire article »

Fukushima Disaster Interviews Clear Up Evacuation Of Daiichi Question

A new report released by Kyodo News seems to clear up what transpired and who may have wanted to abandon Fukushima Daiichi at the height of the meltdowns. The series of events are outlined as far as who said or did what during those hours, these are in time order based on either a date/time stamp or Kyodo’s narrative: 1. Susumu Kawamata (TEPCO) told Banri Kaida (NISA) “I’m sorry.

2nd ALPS Decontamination System Installed At Fukushima Daiichi

2nd ALPS Decontamination System Installed At Fukushima Daiichi

A second ALPS decontamination system is being installed at Fukushima Daiichi and will begin test operations in early September. NRA announced the new system yesterday. The first ALPS system, designed by Toshiba has been plagued with problems that required around a year of testing operations to make it work properly. Another system in testing phases at the plant is a new Hitachi system that would remove some of the isotopes that ALPS can not. image credit | … Read entire article »

Fukushima Daiichi Sea Releases Updated To 157 Billion Bq Per Day

Fukushima Daiichi Sea Releases Updated To 157 Billion Bq Per Day

Yesterday we reported on TEPCO’s admission of ongoing daily sea releases of contaminated water to the Pacific. The TEPCO rep in the press conference cited the tritium level as being 1 billion becquerels per day. The graph submitted by TEPCO to METI showed a quite different amount for the tritium readings. The journalists at the conference prodded TEPCO for actual readings due to the graph having wide ranges and exact numbers were not published along side … Read entire article »

TEPCO To Begin Unit 3 Crane Removal From Spent Fuel Pool

A brief note in the daily reports mentioned that TEPCO will be pausing cooling to the unit 3 spent fuel pool again. This time it is to begin work to remove the refueling crane that fell into the pool during the blast. This work is obviously risky to an extent as they try to remove the heavy refueling crane from the damaged fuel pool. TEPCO previously installed a flexible dam in the pool to try … Read entire article »

TEPCO Failed To Deliver Needed Equipment To Fukushima Daiichi At Height Of Disaster

NHK is reporting this new admission as coming from the late plant manager Masao Yoshida. He discussed problems with getting desperately needed equipment to the plant during the meltdowns. TEPCO sent batteries needed to try to operate control room equipment without any notice of the size or voltage of the batteries. Most batteries were too heavy to carry. Workers had to waste time sorting through the batteries to find ones that were usable. Yoshida also noted … Read entire article »

Muon Detection Tests Begin In Japan Towards Fuel Detection at Fukushima Daiichi

Muon Detection Tests Begin In Japan Towards Fuel Detection at Fukushima Daiichi

A sample testing box set was tested at JAEA’s Tokai reactor in late July. The tests helped them come up with what they think will be proper shielding for the detectors. IRID reports that they think about 10cm of shielding should be enough to enable detectors to be installed at Fukushima Daiichi. There will still be considerable challenges to an actual installation. In order to do the actual detection on the containment structure of each reactor, … Read entire article »
