Flame disappear Fukushima Daiichi nuclear power plant No. 4


16 around 5:45 am, employees of TEPCO has confirmed that the fire is up from the No. 4 reactor building has Fukushima Daiichi Nuclear Power Station, and disappeared 30 minutes after the fire TEPCO announced.

16 around 5:45 am, fourth floor of Building No. 4 reactor at the Fukushima Daiichi nuclear power plant, Tokyo Electric found that employees have come up near the northwest corner of the fire with a fire report. 6:15 am approximately 30 minutes later, was confirmed by several tens of meters away, is that the fire had become invisible. The field, in much the same as that in the morning where there were 15 fire, is that it is located where the speed of the device to adjust the pump to send water reactor. According to TEPCO, the value of the radiation field is high, all that away, now had to consider and how to check the status of the fire and from the outside. Is that not injured. The No. 4 is found in the fire at 9:30 am so 15 days, TEPCO has since disappeared, had been used in nature and cause of the fire is unknown.

Apparently they can not see flames anymore but do not know anything else about that status.

URGENT: Fuel rods damage at Fukushima's 2 reactors estimated at 70%, 33%

TOKYO, March 16, Kyodo

An estimated 70 percent of the nuclear fuel rods have been damaged at the troubled No. 1 reactor of the Fukushima No.1 nuclear power plant and 33 percent at the No. 2 reactor, Tokyo Electric Power Co. said Wednesday.

The reactors' cores are believed to have partially melted with their cooling functions lost after Friday's magnitude 9.0 earthquake rocked Fukushima Prefecture and other areas in northeastern and eastern Japan.

Fire erupts again at Fukushima Daiichi's No. 4 reactor
A new fire breaks out in the No. 4 reactor at the Fukushima Daiichi nuclear complex. The plant's operator says the fire reignited because an initial blaze was not completely extinguished.

By Carol J. Williams, Times Staff Writer

March 15, 2011, 4:12 p.m.
Another fire at Japan's stricken Fukushima Daiichi (No. 1) nuclear power complex broke out early Wednesday, compounding the spree of disasters expected to take historic peacetime tolls on the nation's people and economy.

The latest blaze broke out in the No. 4 reactor at the nuclear complex on the northeast coast where a plume of radiation escaped Tuesday, sending background radiation levels soaring to degrees that authorities conceded were harmful to anyone with prolonged exposure. The plant's operator said the fire reignited because an initial blaze was not completely extinguished, the Associated Press reported.

Here's the photo I was looking for. It clearly shows the short distance between the spent fuel rods "swiming pool" & the reactor (in the background):

Re: Japan - Fukushima Daiichi Nuclear Power Plant Crisis - Units 1 - 6 Reports, News, Graphics

Thanks Denise, nice job with the site maps. The radiation readings given in the detailed NISA reports http://www.nisa.meti.go.jp/english/index.html tend to have long sections like this

The measurement of radioactive materials in the environmental monitoring area near the site boundary conducted by a monitoring car in considering the wind flow, confirmed the increase in the radioactivity compared to the radioactivity at 07:30, March 14.
MP3 (Monitoring at North West of Site Boundary for Unit 2) : 231.1 micro Sv/h (14:30 March 14)
MP4 (Monitoring at north- west of Site Boundary for Unit 2 : 56.4 micro Sv/h(04:08 March 14)

which are difficult to interpret unless you know, or can make an educated guess as to, where MP4, portal or NW gate are in relation to the probable sources of radiation release e.g. steam venting or the fire in the dried out moonpool at reactor 4.

From the first nuclear power plant near the "white smoke"
11:10 am May 16

NHK helicopter before 10 am, but that is a kind of white smoke rising from near the Fukushima Daiichi Nuclear Power Station, has been confirmed. Kindof looks like smoke blowing intermittently. NHK helicopter is shot from above 30 km or more away from nuclear power plants.

The TV report in English is saying the smoke is near Unit 4, but the corresponding article in Japanese suggests Unit 3 ---

As for “white fume” place 3 near machine?

March 16th 10:38 am Japan time

16th 10 o'clock in the morning before, you verified that those like the smoke where the NHK helicopter is white from near the Fukushima first nuclear power plant have risen.Concerning this, as for Tokyo Electric Power “being able to verify actual place it is not. If you see with image, the place 3 is seen as near the machine.There is a possibility of vapor, but in the future we would like to investigate details”, you say. As for those like the smoke in order to have blown out intermittently, it is visible from image.It photographs the NHK helicopter, from the sky where 30 kilometers or more it is far from the nuclear power plant.

Follow on from #145 above;

More reactor trouble: Fukushima No. 5 loses coolant
09:19 PM
Adding to the crisis at the Fukushima Dai-ichi plant, the cooling level has fallen in the No. 5 reactor, Japan's nuclear safety agency says.

The reactor stopped safely for inspection after Friday's magnitude 9 quake, but the tsunami damaged a diesel generator that circulated the coolant, NHK writes. Pressure built up, so a relief valve was opened, thereby reducing the coolant.

To compensate, workers are using the diesel generator for reactor No. 6 to pump water to cool both reactors.

"White smoke" or near the No. 3 place

10:55 am March 16

Before 10:00 am on May 16, NHK has confirmed that the kind of white smoke rising from the Fukushima Daiichi Nuclear Power Station near the helicopter. For this, TEPCO Hukushima office press conference "can not confirm the field. Unless you see in the picture, where Unit 3 is expected to close. There is a possibility of water vapor, will want to study more" and spoke. He added, "the story of the local employees, because they can not get out of the building so far out in the field or something like that smoke, you can not see," he said. From the video, like a balloon that looks like smoke intermittently. NHK helicopter is shot from above 30 km or more away from nuclear power plants.

"White smoke is water vapor possible"

11:29 am March 16 Japan time

16 before 10:00 am, white smoke rises from near the kind of Fukushima Daiichi Nuclear Power Station, TEPCO press conference, "As far as visuals, Unit 3 is expected to close, there is the possibility of steam" and talked.

According to TEPCO, the pool of spent fuel are stored in the Unit 3 cooling can not state that it is possible to evaporate water to the pool temperature to rise. Before 10:00 am on May 16, NHK helicopter and confirmed that the white smoke rising from some kind of Fukushima Daiichi Nuclear Power Station near. For this, TEPCO press conference "can not confirm the field. Unless you see in the picture, and was seen near the location of Unit 3, there is a possibility of water vapor, will want to study more" and told . According to TEPCO, the steam out as a possibility is that it is considered that the evaporation of pool water that is stored spent fuel. The pool of Unit 3 has stored the fuel assemblies of the body 514, now that it no longer be cool, trying to possibly exposed fuel is going down the pool water. From the video, like a balloon that looks like smoke intermittently. NHK helicopter is shot from above 30 km or more away from nuclear power plants.

North wind around the nuclear power plant expected to increase

11:29 am March 16 Japan time

Wind around the Fukushima Daiichi Nuclear Power Station TEPCO expected during the night of 16 blows from north to south for 16 days, the wind is expected to increase gradually.

According to the agency, in the vicinity of the Fukushima Daiichi Nuclear Power Station, is entering the observations after the earthquake, followed by the state and can not be observed wind direction and wind strength. In Yamada Nakoso in Iwaki, Fukushima Prefecture away more than 60 kilometers south of nuclear power stations Fukushima Daiichi is currently 11:00 am, they wind northwest of four meters, even in the vicinity of nuclear power plants, between north and south is believed that the weak wind. According to local meteorological observatory, Fukushima, because after this gradually increase the pressure pattern of the wintry wind is expected to increase gradually toward the northwest to the southeast of the sea from the landward side.
