Ugh! Who wants to do that? Well, this is one time when you don't have to! In this webinar, Team Samurai will personally walk you through the site and show you many of the useful and powerful features that even long-time users probably never knew existed.

Another reactor at Fukushima nuke plant loses its cool-- that makes SIX reactors!

Tokyo Electric Power Co. said Sunday another reactor of its quake-hit Fukushima nuclear power plants had lost its cooling functions, while at least 15 people at a nearby hospital were found to have been exposed to radioactivity.

The utility supplier notified the government early Sunday morning that the No. 3 reactor at the No. 1 Fukushima plant had lost the ability to cool the reactor core. The reactor is now in the process of releasing radioactive steam, according to top government spokesman Yukio Edano.

It was the sixth reactor overall at the Fukushima No. 1 and No. 2 plants to undergo cooling failure since the massive earthquake and ensuing tsunami struck Japan on Friday.

The disaster raised fears over radioactive leaks from the plants after cooling systems there were hampered, most seriously at the No. 1 reactor.

An explosion Saturday at the No. 1 plant blew away the roof and the walls of the building housing the No. 1 reactor's container.

The government and nuclear authorities said there was no damage to the steel container housing the troubled No. 1 reactor, noting that the blast occurred as vapor from the container turned into hydrogen and mixed with outside oxygen.

Tokyo Electric Power has begun new cooling operations to fill the reactor with sea water and pour in boric acid to prevent an occurrence of criticality. Chief Cabinet Secretary Edano said in a press conference Sunday morning that there had been no major changes in the results of monitoring radioactivity near the No. 1 reactor.

Following the explosion, the authorities expanded from 10 kilometers to 20 km the radius of the evacuation area for residents living in the vicinity of the Fukushima plants.

The Fukushima prefectural government said Saturday that three people had their clothes contaminated with radioactive substances while fleeing from the No. 1 nuclear plant.

The Fire and Disaster Management Agency said Sunday that 15 people were found to have been contaminated at a hospital located within 10 km from the No. 1 reactor. Edano said there was a possibility that nine people who fled on a bus had been exposed to radioactivity.

Seems odd---that coolant was lacking and there was NO WAY to repair that?

I saw a news report---the electrical power failed. This powers the circulation pump(s).

Not surprising---given an 8.9 earthquake.

But the Back-Up system (diesel generators) also failed. Though it was not explained why or how.

The Back-Up/Back-Up system (batteries) may have been operational for a time but obviously would need power at some point to recharge or replacement batteries. What a mess.

Very odd that the diesel generators failed. Almost like they were sabotaged. Combined with the intel that the Fukushima Daiichi plant was scheduled to be mothballed in March 2011 (yep, this month) and I smell an insurance scam a la 9/11 Twin Towers when old Silverstein made out like a literal bandit.

In the future a way to gravity feed water into the reactors should be in place. Worst case scenario blow a dam and kill the reactor rods through a last ditch canal to each reactor.

They should build these plants ironically below a power dam. Use the forces of nature to secure the reactors by opening the floodgates. It makes me sick to see these disasters.

Yesterday---news reports indicated that the Japanese were trying to put in place a *power line* to get the Coolant Pumps operational.

The "line" is said to be 6/10ths a mile long.

I can't help but wonder---why go thru all of that?

Use a massive lifting helicopter to drop-ship a giant diesel generator package...

Another thing--with everything being in proximity to these huge explosions---are those pumps undamaged/even operational?

Too little information is being offered by the Japanese Gov't...
