Geothermal power is NOT going to replace all of Japans major nuclear power. He is right that the drive towards the US style light water reactor was for access to nuclear processing NOT power, but it is not too late to learn.

CANDU (heavy water reactors) are designed for passive shutdown safety and would likely have survived the event. Since this is a VERY extreme event that means that there is almost NO likelihood of a geophysical event that would cause them to fail.

Also note that his point about japan being crisscrossed with faults is not relevant. The damage was from the Tsunami for which there were inadequate defenses and the failure of backup power from the subseqent flooding. Without a steady and active cooling, light water reactors can 'melt down' even when 'shut down' at the time.

Fukushima has a long history of cover ups & studies NOT heeded:

1976: Falsification of safety records[edit]
Fukushima Daiichi was central to a falsified-records scandal that led to the departure of senior TEPCO executives.

In 2002, TEPCO admitted falsifying safety records for unit 1. The scandal and a fuel leak at Fukushima Daini forced the company to shut all 17 of its reactors.[75] A power board distributing electricity to temperature control valves was not examined for 11 years.

1991: Back-up generator of reactor 1 flooded[edit]
On 30 October 1991, one of two backup generators of reactor 1 failed, after flooding in the reactor's basement. Seawater used for cooling leaked into the turbine building from a corroded pipe at 20 cubic meters per hour, as reported by former employees in December 2011.

2008: Tsunami study ignored
//////////
The most comprehensive & least likely publicity affected report about casualties from Fukushima was the Ten Hoeve & Jacobson evaluation. Mark Jacobson is the central authority to evaluation of air pollution standards & deaths, post 3-way catalytic converter implementation on California vehicles. His ascendency on air pollution effects on human physiology is unquestioned.

Nuclear munitions plant Fukushima Dai Ichi has been covered up by the highest ranks of the japanese governement for a while. Look for USGov to not to expose Japanese breach of NPT, as long as the nips keep their reactors shut and keep paying the petroleum exaction&jyzia.

What are you saying?

Make it clear for a change.

Whatever you are saying is not as important as this one:

However, as experts have warned, the decommissioning process currently being undertaken by TEPCO at Fukushima—particularly at the damaged and sinking Reactor 4 building—is exceedingly fragile.

And as long-time anti-nuclear activist Harvey Wasserman explained to Common Dreams earlier this year, "The potential radiation released in this situation can only be described as apocalyptic."

The cesium alone would match the fallout of 14,000 Hiroshima bombs. If the job is botched, radiation releases could force the evacuation of all humans from the site, and could cause electronic equipment to fail. Humankind would be forced to stand helplessly by as billions of curies of deadly radiation pour into the air and the ocean.

"The potential radiation released in this situation can only be described as apocalyptic"

And cities being wiped out by exploding mile-long oiltrains is a pastoral idyll?

"Humankind would be forced to stand helplessly by as billions of curies of deadly radiation pour into the air and the ocean."

Given the amount of water in the pacific Ocean, the level of radiatioactivity would be hardly detectable... much less deadly.

BTW that's what should have been done from the very beginning (washing the inside of melted reactors into the ocean)..
