@Nancy: A ways back you were discussing a spreadsheet that would automatically update a graphic. Radioguy wanted the column heading translated. Perhaps he will be back and respond.

@dh I think I know what one. Do you want me to just post the link to the sheet?

Live cam showing a stream of black smoke rising above #1

@Deb Thanks. I see it as well.

@Deb, yep I see it also. black smoke out of #1 is unusual.

is what I was thinking, very unusual

What part of the reactor might that be coming from?

I think this is a pretty big deal. The cesium levels measured above it were very high. What's coming out know!?

hard to tell what it is from. Looks like middle but doubt that with the roof intact but flat. Otherwise maybe on the front (camera view) edge. I don't know for sure how #1 is oriented. If it is like the others the SFP would be on the far right like 4 is.

Thanks Deb!

@LM You could be right, I am looking thru the past couple hours of video, see what I find.

Thanks for looking, Deb!

TEPCO: reactor damage includes holes
The operator of the troubled Fukushima Daiichi nuclear power plant says data analyses suggest that damage to its reactors may have caused holes inside them of up to 10 centimeters across.

Reactors 1 through 3 at the plant suffered nuclear fuel meltdowns after the March 11th earthquake and tsunami. This is likely to have created holes and cracks at the bottom of the pressure vessels protecting the reactor cores and damaged the containment vessels.

Massive amounts of highly radioactive water also leaked from the structures.

Tokyo Electric Power Company analyzed the changes in pressure levels inside the pressure and containment vessels after the quake to gauge the scope of the damage.

TEPCO said the analyses show that a hole 3 centimeters across may have been created at the containment vessel of the Number One reactor 18 hours after the quake. It added that a hole as large as 7 centimeters across is also likely to have been created at least 50 hours after the quake. www3.nhk.or.jp

@Deb That's interesting...I didn't think they were allowing vessels that close unless they were tied to the water storage.

@Deb Probably not a coincidence.

Radioactive water transfer halted at Fukushima

Tokyo Electric Power Company, operator of the Fukushima Daiichi nuclear power plant, has suspended work transferring highly radioactive water from two of the reactor buildings to storage facilities at the plant.

The utility stopped the work at 9 AM on Wednesday, saying it needed to work on power supply lines.

It said when that work is finished it will resume the transfer of water from the Number 2 reactor, but not from Number 3, because storage facilities are nearly full.

Contaminated water accumulating in the reactors' turbine buildings and utility tunnels is hampering the utility's efforts to get the crippled nuclear plant under control.
Tokyo Electric is aiming to transfer a total of 14,000 tons of contaminated water from the two reactor buildings to the storage facilities.

That work is about 90 percent complete at the Number 3 reactor building, but can't be finished until the utility determines how much more storage space is left.

High levels of cesium detected above No.1 reactor

The operator of the Fukushima Daiichi nuclear plant says the density of radioactive cesium above the No.1 reactor is 18 times the permissible level for the edge of the plant's compound.

Large amounts of radioactive substances have been released into the air since reactor cores and buildings were damaged, but measurements were not available.

On Sunday, Tokyo Electric Power Company began measuring the density of radioactive elements above the No.1 and No.4 reactors.

The firm used instruments attached to the crane pumps that are injecting water into the reactors.

TEPCO detected 360 becquerels of cesium-134 per cubic meter above the No.1 reactor, where most of the fuel rods are believed to have melted. The amount is 18 times the allowable limit for the plant's perimeter.

The firm also discovered 7.5 times the limit of cesium-134 above the No.4 reactor, which has no fuel in its core. The substance is believed to have come from the fuel storage pool and the neighboring No.3 reactor.

TEPCO says it will measure the levels of radioactive elements above the No.2 and No.3 reactors. It also plans to cover the reactor buildings with polyester sheets to prevent the further dispersal of radioactive materials into the air.
