Can Fukushima’s Spent Fuel Pools Catch Fire?

21 08 2012

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. . . . (more + video)

Broken Down California Nuke Plant, San Onofre, Wants to Re-Start

16 05 2012

The LA Times has this:

Edison’s San Onofre plan could make things worse, consultant says

A consultant who has criticized Southern California Edison’s handling of the troubled San Onofre nuclear plant issued a report Tuesday saying the utility’s proposed solution for bringing the plant back online could make the issues worse.

The plant has been offline more than three months because of excessive wear in steam generator tubes that carry radioactive water. The wear appears to be occurring when the plant is running at full power and the rate of steam flows causes the tubes to vibrate and rub against each other and against support structures, Edison officials have said. . .  (more)

Expert: San Onofre’s Leak Problems Run Deep

. . . .  After the January leak, inspections showed that hundreds of the tubes were nearly shot, and eight burst in pressure tests — an uncommon amount of wear for steam generators only two years old. . . . . (more)

May 3 Fukushima Daiichi Explosion – MORE

4 05 2012

The video we like with the footage speeded up captured a large explosion May 2nd.   What we saw on the Live Cam and posted here on May 3rd looked just like this May 2nd explosion.  We just didn’t get the screen grab til after the flame ball died down a lot.  

So the May 2nd explosion blew AGAIN on May 3rd.

Today on ENE-News they have an item with Arnie Gundersen comments and they added the speed-up footage with the dramatic explosion.  The footage in the link is from May 2 explosion. It shows it very clearly.

Gundersen: “The water is steaming and boiling” still at Fukushima; “Yes, there’s some radiation being given off ”

MAY 2 EXPLOSION

In the video check the wave of bright light that wafts across the foreground at the 55 second spot.  And look at the later big flame up.  We got these stills from the video using the pause feature:

Incredibly, Japan is still lying to tourists. They insist there is NO radiation in Japan outside the evacuation zone [!!!].

Ft. Calhoun nuclear plant “likely would have melted down” if operators were not forced by NRC to make enhancements before major flooding

30 04 2012

. . . According to Arnie Gundersen, on WBAI.

“Back in ’09 [the NRC] did force Ft. Calhoun to do flood enhancements. Had they not done that, the plant likely would have melted down.”

Fukushima – Arnie Gundersen says TEPCO Cannot Control Criticality at Wrecked Plant

23 08 2011

“Newly released neutron data from three University of California San Diego scientists confirms Fairewinds’ April analysis that the nuclear core at Fukushima Daiichi turned on and off after TEPCO claimed its reactors had been shutdown. This periodic nuclear chain reaction (inadvertent criticality) continued to contaminate the surrounding environment and upper atmosphere with large doses of radioactivity.

STORY with VIDEO: NRC now says reactors and containments have breached and released plutonium off-site — “Much worse” than if from spent fuel pools

Gundersen on lethal radiation levels: Even higher measurements to come — Nuclear core has leaked out and is on floor

5 08 2011

TEPCO has discovered locations on the Fukushima plant site with lethal levels of external gamma radiation. Fairewinds takes a close look at how this radiation might have been deposited and how similar radioactive material would have been released offsite. . .
