More Lessons From the Fukushima Daiichi Accident: Containment Failures and the Loss of the Ultimate Heat Sink

More Lessons From the Fukushima Daiichi Accident: Containment Failures and the Loss of the Ultimate Heat Sink

In this Monday's video, Fairewinds investigates a recently released report from Tokyo Electric. Arnie Gundersen discusses TEPCO's latest analysis that, almost two years after the accident, fully substantiates Fairewinds long held position that the explosion at Fukushima Daiichi Unit 3 was the result of a detonation shock wave. Arnie also discusses troubling reports that the Nuclear Regulatory Commission has been avoiding the analysis of damage to many nuclear plants' emergency cooling systems (Ultimate Heat Sink) from storm surges, tsunamis or dam failures. The ramifications of both of these issues on old designs and also the AP1000 are also analyzed in depth.

It Could Have Been Worse

It Could Have Been Worse

Fairewinds analysis of the triple meltdowns at Fukushima Daiichi determined that other Japanese reactor sites were also in jeopardy because their cooling water systems were destroyed by the same tsunami. In this film, Fairewinds provides evidence that cooling systems for 24 out of 37 diesel generators were shut down by the tsunami and that 14 additional nuclear reactors were impacted. Finally, Fairewinds also recommends that the criteria of the international nuclear accident scale have a Level 8 added. The addition of a Level 8 would reflect the nuclear accident scenario at a multi-reactor site that significantly changes the risk factors to the general public and emergency evacuation procedures.

Can Spent Fuel Pools Catch Fire?

Can Spent Fuel Pools Catch Fire?

In this Fairewinds’ feature, Fairewinds Associates Chief Engineer Arnie Gundersen analyzes a US government national laboratory simulation video that shows nuclear spent fuel rods do catch fire when exposed to air. This simulation video proves Fairewinds’ assertions that nuclear fuel rods can catch fire when exposed to air, and Arnie discusses the ramifications of this phenomena if the Fukushima Daiichi Unit 4 spent fuel pool were to lose cooling water. The Sandia National Laboratories video in its entirety can be seen here.

As Japan Says Fukushima Daiichi Disaster "Man-Made" & "Preventable," Fears Grow for Nuclear Plants Worldwide

As Japan Says Fukushima Daiichi Disaster "Man-Made" & "Preventable," Fears Grow for Nuclear Plants Worldwide

Democracy Now's Juan Gonzalez hosts Arnie Gundersen of Fairewinds Energy Education. A Japanese parliamentary inquiry has concluded last year’s nuclear meltdown of the Fukushima Daiichi nuclear power plant was "a profoundly man-made disaster — that could and should have been foreseen and prevented." Arnie Gundersen and Juan Gonzalez talk about the report and what it means for U.S. nuclear facilities, in particular the 23 with a similar design to the Fukushima Daiichi plant.

Fukushima Daiichi: The Truth and the Future

Maggie and Arnie Gundersen of Fairewinds Energy Educationwere invited to prepare a video for presentation in Kansai, Japan on May 12th 2012.  They answered specific questions submitted in advance by symposium organizers regarding the condition of the spent fuel pool at Fukushima Daiichi Unit 4. Fairewinds analyzes the explosion at Fukushima Daiichi Unit 3. Also, Arnie discusses what the future may hold for Japan if it chooses a path without nuclear power.

Tokyo Soil Samples Would Be Considered Nuclear Waste In The US

Tokyo Soil Samples Would Be Considered Nuclear Waste In The US

While traveling in Japan several weeks ago, Fairewinds’ Arnie Gundersen took soil samples in Tokyo public parks, playgrounds, and rooftop gardens. All the samples would be considered nuclear waste if found here in the US. This level of contamination is currently being discovered throughout Japan. At the US NRC Regulatory Information Conference in Washington, DC March 13 to March 15, the NRC's Chairman, Dr. Gregory Jaczko emphasized his concern that the NRC and the nuclear industry presently do not consider the costs of mass evacuations and radioactive contamination in their cost benefit analysis used to license nuclear power plants. Furthermore, Fairewinds believes that evacuation costs near a US nuclear plant could easily exceed one trillion dollars and contaminated land would be uninhabitable for generations.
