These videos are VERY informative. They are translated very well also..
Linked from most recent, but ALL are worth watching. Very technical but easily understood. They are each about 2 hours long is the only draw back, but very worth watching, or listening to in the background.

Re: Japan - Fukushima Daiichi Nuclear Power Plant - Unit 1 Meltdown & Radiation released, Unit 3 had hydrogen explosion, Unit 2 problem cooling & possible fuel rod failure, and release of radioactive material

My understanding is that MOV is only in Unit 3. If anyone has different information, please post.

Thanks!

If you mean MOX fuel, yes, only #3 has that.

Emergency exposure limits are raised

1 hour 26 minutes 3 twitter tweet on May 16 (NHK-click and leave the site)

For workers hitting tasks such as cooling of the reactor at a nuclear power plant Fukushima Daiichi, the national standards so far as not allow time enough work beyond just limits the amount of exposure to radiation, the Ministry of Health, Emergency if and only if, so far decided to increase the 2.5 maximum amount of exposure to 250 mSv times hit.

Health effects of radiation, is indicated by a unit called the Sievert, and individual differences more than 250 mSv, but have been with the acute symptoms begin to appear, such as a temporary decrease in white blood cells . About this ministry, and were thoroughly professional and as such impact on workers, "in addition to international standards has been limited to the amount of 500 mSv, 250 mSv or less acute obvious medical knowledge out there is no health hazard. in order to prevent the spread of nuclear disaster is inevitable decision, "I said.

Use of helicopters is difficult to pool water injection

March 16 3:36 3:00 3 twitter tweet in (click on the site leaves the NHK)

In Unit 4 of Fukushima Daiichi Nuclear Power Station, they are unable to store nuclear fuel pool cooling, TEPCO was considering putting in a pool of water from the air transport helicopters, used helicopters The method proved to be difficult.

The primary Fukushima Daiichi, when the earthquake, the No. 4 had to stop driving for a regular inspection, the temperature of the water in the pool to store nuclear fuel to 84 degrees high 40 degrees around than usual at the time of the early morning of July 14 they rise, then a fault in the equipment, making the temperature 測Renaku. If this situation continues, the melt or fuel, or is likely due to the generation of hydrogen, Tokyo Electric Power as a way into the pool water, carry water when you work like wildfire using firefighting helicopter was intended to be placed over a damaged portion of the roof of the building from above. But tens of meters away and that the distance between the damaged area and pool, from a small amount of water transported by helicopter at a time, and how to use helicopters, proved to be very difficult. Around the pool, if strong radiation out, away from immediate circumstances, TEPCO has been unable to examine whether injection of water in other ways such as using a fire truck.

Has anyone got a good site plan? Have been looking but not found one yet, it would make understanding the radiation readings around the site a lot easier.

Did find this


which may help in understanding the relationship of the key parts

I first advanced nuclear fuel rod damage
41 min at 4 3 twitter tweet on March 16 (click on the site leaves the NHK)

Little progress in cooling water injection, two groups of three reactors in Fukushima Daiichi nuclear power plant fuel rods are exposed, I found that there is a rapidly moving in the fuel rod damage .

TEPCO's two nuclear reactors at Fukushima Daiichi nuclear power plant, and can crack or small hole, and how much of the entire range of rods based on the amount of radioactive material leaked into the cooling water estimates have shown the results of the Disaster Relief Headquarters in a meeting held on August 15 province. According to that, there is a percentage of damaged fuel rods, the No. 1 ▽, 43 at 1:00 pm was 15%, 3 pm 25 minutes had spread to 70 percent. Also, No. 2 at 14 -▽% 33% means that the rapidly increased to. These two groups are exposed to falling water level of the fuel rods in the reactor cooling water, but work is continuing to inject water inside the water level does not recover enough, the hot rod has been pointed out that it is melting. Continue to damage the fuel rods, making it easier for external leak of radioactive material. Pressure in the two reactors is that there continues to decrease, TEPCO, while carefully watching the trend of this data, we decided to water injection to proceed.

Slightly lower water level in the furnace No. 5

March 16 5:15 am local Japan time

NISA, in a press conference early Sunday morning, 16 at Unit 5 of the primary Fukushima Daiichi was going to have to stop safely so far, it has slightly lower water level in the reactor containing the nuclear fuel to reveal. However, the generator has not received the No. 6 next tsunami, in the Nuclear and Industrial Safety Agency, "you can adjust the amount of water," I said.

According to the Nuclear and Industrial Safety Agency, Unit 5 of Fukushima Daiichi nuclear power plant, the occurrence of earthquakes and tsunamis of the 11th month in a regular inspection, that reactors had been shut down safely. However, nuclear fuel, they have already entered the reactor for commercial operation, it was necessary to keep the circulating water to cool the fuel. However, diesel is damaged by the tsunami, not enough water circulation, there was a higher pressure in reactor. Therefore, the attempt to adjust the pressure in the reactor operation was carried out to open the valve from the steam out there, now 15, 9:00 pm, was down over 1 cm to 2 meters of water nuclear fuel . Exposure of nuclear fuel, but this is the fact that less than 40 cm, 15 hours before 4:00 pm 5.

However, there is a generator has not been a tsunami in No. 6 the next, and now, using generators that they send water into the reactor 2, Unit 6 and the No. 5, NISA In "The amount of water because there is a sound generator can be adjusted" to this.

Accidental release of radioactive materials can not be predicted

In the vicinity of TEPCO's Fukushima Daiichi (Unit 1 - edit) nuclear power plant, which measure the amount of radiation "monitoring posts" Most of the devices, called for work without power after the earthquake, together with the primary wind and weather information If radioactive material leaks, or extend the system to predict how, I found that hardly function.

"SPEEDI" This system is called the Ministry of Economy, Kasumigaseki, Tokyo, has been installed and Nuclear Safety Agency. "SPEEDI", when radioactive material leaked from a nuclear power plant, using a computer to predict the spread of radioactive material in conjunction with wind and weather information such as the value of the radiation observed in many areas. The nuclear disaster, "SPEEDI" is supposed to be helpful in determining the scope of the evacuation and evacuation of residents and the interior data. NISA is "measuring the amount of radiation monitoring posts [many] for work without power after the earthquake] [SPEEDI not get enough of the original function. Now expected to recover not stand, "I said.

"Immediate measures need the No. 4"

3月16日 6:49 Japan time

About what is no longer the cool of the pool to store nuclear fuel in the No. 4 nuclear power plant Fukushima Daiichi, Nuclear and Industrial Safety Agency of the Ministry of Economy, at a press conference early Sunday morning, 16 "water into a fast冷Yasanai become dangerous, "he said, showed the idea that immediate measures must be taken.

Fukushima Daiichi nuclear power plant No. 4 from last November to stop operation for regular inspections, in turn, is placed in the pool for storing all the books were among 548 nuclear reactors. However, could no longer circulate water to cool the pool under the influence of the earthquake, the water temperature at the time of the early morning of July 14, they rise up to 84 degrees high 40 degrees around than usual, then, such as equipment failure, temperature and water level has been 測Renaku. NISA about this at a press conference on the 16th, and added there is a pool of water going down the water to evaporate, "also has a nuclear heat water quickly to insert For example, what has become dangerous.'d better think very optimistic, "he said, showed the idea that immediate measures must be taken. Pool to store nuclear fuel, they become a mechanism to contain the radiation from the fuel can fill with water, if there are no water, melt the fuel, radioactive materials or radiation, it may leak out. In this issue, the Minister 海江田 15, according to the law mandates that water into the pool for quick Electric Power Company.
