Fukushima Daiichi Still Releases 10 Million Becquerels Per Hour

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

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 »

Japan Moves Closer To Nuclear Restarts, But Who Decides?

Japan Moves Closer To Nuclear Restarts, But Who Decides?

Japan’s NRA gave an initial approval towards the Sendai nuclear plant meeting government “safety standards”. There are still other aspects of safety and equipment that NRA would need to approve but there is much more that would have to happen before any reactor was to restart operations. NRA also mentioned they are close to giving an approval to the Takahama nuclear plant. Part of these safety upgrades includes construction of a radiation resistant bunker building/command center … Read entire article »

Fukushima Unit 3 Demolition Spread Contamination 50km, Multiple Instances

Fukushima Unit 3 Demolition Spread Contamination 50km, Multiple Instances

More information has come out about the contamination caused by the demolition work on unit 3. It was not the government, or TEPCO who found this was happening. Researchers from Kyoto University confirmed the problem in March 2014 and alerted the government. Had the university not been operating dust monitors on a regular basis, this issue likely would not have been admitted or known. 4 trillion becquerels were released in the August 19th incident and spread … Read entire article »

TEPCO Contaminated Nearby Town During Unit 3 Demolition

TEPCO Contaminated Nearby Town During Unit 3 Demolition

TEPCO has admitted to re-contaminating the area around Minamisoma after being confronted by the agriculture ministry. Rice in Minamisoma was found to be over the government radiation limit of 100 bq/kg. Upon further inspection the ministry found it was the outside of the rice plants that had the most contamination rather than the rice kernel itself. This indicated contamination fell on the plants rather than being taken up from the soil. Now TEPCO is admitting on … Read entire article »

Fukushima Disaster Causes Nuclear Workers To Flee To Solar, Creates New Robotic Industry

Fukushima Disaster Causes Nuclear Workers To Flee To Solar, Creates New Robotic Industry

Workers for TEPCO have been leaving at a rapid pace. Between cuts in pay and the social stigma of working for the company, many have chosen to leave. What is more interesting is how many have left the nuclear industry all together and are now working for new solar power companies. This could become an even larger trend as other nuclear power utilities see their businesses flounder. The disaster has also caused a drastic shift in … Read entire article »

Saturday Quake, Aftershock of 3-11 Quake

The 6.8 quake in Japan on early Saturday morning generated tsunami warnings and caused a few evacuations. So far no significant damage has been reported from the quake. It has however been classified as an aftershock of the 3-11 quake that kicked off the massive disaster in Fukushima.

TEPCO Submits Plan For Fuel Removal At Unit 3 Fukushima Daiichi

TEPCO submitted plans to the NRA for spent fuel removal from unit 3. This included more detail on how they intend to install a cover and remove transit casks from the building. The defueling building cover bridges the original reactor building, putting the load on the existing scaffolding system and an accessory building. This structure avoids contact with the reactor well, known to have high radiation levels. TEPCO did not mention any measures to prevent radiation issues from the fuel canal between the reactor and the spent fuel pool. They also do not mention anything about worker exposures or how human work would be conducted. Estimated radiation levels in the area are as high as 1 sievert/hour.     The fuel casks would be moved out of the pool to the left side … Read entire article »

US Taxpayers May End Up Paying For Fukushima Disaster

The US and Japanese governments are one step closer to a liability agreement that would put US taxpayers on the hook for millions of dollars towards the clean up of Fukushima Daiichi. Other countries that are party of the treaty would also be expected to put money in to the disaster site. The US has been pushing Japan to agree to this by withholding some assistance until Japan signs the treaty. The treaty also shelters major nuclear companies like Hitachi-GE, Toshiba and Areva from liability while pushing costs back on taxpayers. General Electric is a major proponent of this treaty.
