22.06 Legible blackout schedule up at Mainichi:
21.25 Map showing the two major power networks in Japan. Energy conservation is absolutely necessary for those living on the 50kHz network grid in the East of Japan. Of course, saving energy is important, so those on the Western 60kHz are still encouraged to cut back during these difficult days. (via @Mutantfrog)
21.03 Tentative schedule of power outage locations and times:
20.30 Prime Minister Kan calls the earthquake the greatest crisis in Japan in 65 years since WWII. He is calling for all people to conserve power in Japan by turning off appliances and unplugging devices from the power outlets. Nuclear power stations in two locations in Tohoku and Kanto as well as thermal power stations in 5 locations have stopped functioning. This has led to a 10 million kw shortage (equaling the annual electric usage for 2500 homes – via @Goldie_luvmj), meaning that it is necessary to utilise controlled blackouts to minimise the power consumption and disruption. The blackouts are scheduled to begin from tomorrow.
20.20 The water gauge at unit 3 in Fukushima is not rising as water is pumped in to cool the system. There is concern that the water is not being adequately applied and the task force is looking in to the matter.
19.20 Remember, even thought the tsunami warnings have been cancelled, there is still a 70% chance of a level 7 earthquake occurring in Japan within the next 3 days. Be prepared.

16.14 Eyewitness account by @jamesinjapan on the quake.
That night, however, was terrifying – not because of any particular event, but as a result of our fear. Aftershocks hit time after time, little shakes and big bumps, each time forcing us to question whether it was time to flee the building.
We started the night with just a single emergency rucksack on standby at the entrance, but through the early morning we had assembled two further bags with clothes and blankets – basic essentials that might make a disaster more comfortable. By 06:30, unable to withstand the constant stress of the earthquake alert system, I drifted off.
16.12 Stunning pictures of the aftermath:
16.00 Explanation of the state of the units in Fukushima plant 1.
Below, units 4-6 are under examination.
The orange section at the bottom shows the outer storage building for the reactor. High pressure is building up inside it at units 2 and 3. At unit 1, it has been filled with sea water to prevent further damage or radiation leaks.
The blue section shows the cooling situation. unit 3 is currently being cooled with water, unit 2 is still unstable.
The green section shows the power outage. None of the reactors are functioning.
15.40 Unit 3 at Fukushima plant 1 is in trouble. Topping up the water in the cooling system is failing and a hydrogen explosion may be imminent. Government says that it will not affects the nuclear reactor or core. Currently radiation levels there are at 184.1 micro sieverts/hour. (via NHK t.v)

14.44 Mirrored the report on who can and can’t give blood in Japan (from Mutantfrog)
Who can and can not donate blood in Japan
March 13th, 2011 by Roy Berman[Correction: Accidentally typed Australia at first below, should have been Austria all along.]
There has been a lot of confusion over who exactly is allowed to donate blood according to Japanese regulations, especially foreigners. To try and clarify the situation I have translated the entire list of categories of persons who are NOT allowed to donate blood in Japan, from the Japanese Red Cross official web page.
The biggest confusion is regulations relating to foreigners, especially because of mad cow disease aka spongiform encephalitis (Creutzfeldt–Jakob disease).
The following categories of people are BANNED from donating blood in Japan.
Please do not clog blood donations centers if there is even a chance you fall into one of the following categories, and instead find some other way to help.
Please also note first of all that ANYBODY who has entered Japan in the last four weeks may NOT give blood.
First, the rules relating to BSE/Mad Cow Disease
To clarify the below rules, please calculate your TOTAL amount of time spent in ANY of the countries in categories 1~4 during the relevant risk period for that country. If your total period of time in a high-risk country during a high-risk period is equal to 6 months or more than you are banned from blood donations for life.
Similarly, if you have spent a total of 5 years total in any of the countries listed in all 6 categories during risk periods, then you are banned from blood donations for life in Japan unless a new medical test in the future causes the regulations to change.
Please note that no countries in North or South America are on this list; despite the worries over Canadian/US beef it was never transmitted to humans.
Anybody who has spent a TOTAL of 30+ days in the UK between the years 1980 and 1996.
Anybody who has spent a TOTAL of 6+months in the UK between 1997 and 2004. (Note: Also include period of stay under category 1,3,4 in this total.)
Anybody who has spent a TOTAL of 6+ months in Ireland, Italy, Holland, Saudi Arabia, Spain, Germany, France, Belgium, Portugal, between the years of 1980 and 2004. (Note: Also include period of stay under category 1,2,4 in this total.)
Anybody who has spent a TOTAL of 6+ months in Switzerland between the years of 1980 and 2004. (Note: Also include period of stay under category 1,2,4 in this total.)
Anybody who has spent a TOTAL of 5+ years in Australia, Austria, Greece, Sweden, Denmark, Finland, Luxembourg, between the years 1980 and 2004. (Note: Also include period of stay under category 1,2,3,4,6 in this total.)
Anybody who has spent a TOTAL of 5+ years in Iceland, Albania, Andorra, Croatia, San Marino, Slovakia, Slovenia, Serbia, Czech Republic, Vatican City, Hungary, Bulgaria, Poland, Bosnia, Herzegovina, Macedonia, Malta, Monaco, Montenegro, Norway, Lichtenstein, Romania, between the years of 1980 through the present day. (Note: Also include period of stay under category 1,2,3,4,5 in this total.)
Next the rules relating to blood parasite diseases.
Anybody who has entered the country in the past four weeks.
Anybody who has entered Japan after visitinga malaria high-risk area within the last year. This is true even if you were only at a resort area of the country. HOWEVER, if you have been specifically tested for malaria and been found negative you may donate blood.
Anybody who has entered Japan after living in a malaria high-risk area within the last three years.
Anybody who has ever lived in a region known for Chagas Disease, AKA American trypanosomiasis. (This is a blood parasite like malaria.)
Anybody recently returned from Africa or who has lived in Africa and ever tested positive for African trypanosomiasis (African sleeping sickness.)
Anybody who has ever tested positive for babesiosis, another blood parasite most commonly found in tropical regions such as Africa or Latin America.
Also anybody who has engaged in medical work, research, field work, etc. in any regions known for similar diseases should not donate blood.
Last are other categories of persons who may not donate blood.
Anyone who has or has had heart disease, or malignant tumor,
Anyone who has rheumatic fever or is on antibiotics due to risk of rheumatic fever
Sufferers from any convulsive disorder
Sufferers from blood-loss related diseases such as hemophilia or purpora.
Anyone with medicine allergies, nephritic syndrome, chronic inflammation disorders.

Anyone who has ingested marijuana or other psychoactives within the last year
Any man who has engaged in homosexual behavior
Anyone with a history of sex with anonymous partners
Anyone who has been treated for hepatitis A within the past 6 months. Also, since it is often transmitted by shellfish, anybody whose family member has been treated for hepatitis A within the past 1 month. Hepatitis B and C stay in your system, so you are permanently banned.
Anybody who has ever RECEIVED a blood transfusion. (Due to the possibility of viruses as yet unknown to medical science.
Anybody who has gotten a body piercing (ears included) within the past year.
Anybody with a piercing on a mucous membrane such as the lip, tongue, nose, no matter when you got it.

Anyone vaccinated against smallpox within the past 2 months.
Anyone given an antisterum for tetanus, snake bite or other poison, gas gangrene, botulism etc. within the past 3 months.
Anyone who has had dental surgery that caused bleeding within the past 3 days.
14.21 Unit 3 at Fukushima plant 1 is recovering after water levels cooling the reactor were topped up.
14.10 How the World is reporting on the Japan quake:
14.04 The latest on the state at Fukushima. Unit 1 has been filled with sea water and is under control. Units 2 and 3 have experienced problems and radioactive vapour has been released into the atmosphere to reduce pressure, as was done with the reactor in the first unit.
On Sunday, they announced that the cooling system at a second reactor in the same aging plant had failed, forcing officials to release radioactive vapor into the atmosphere. At least 210,000 people were told to evacuate the areas.
The cooling systems at three other reactors at a second nuclear plant had also failed, officials said. While cooling might still be revived, if it could not, these reactors could also require emergency cooling, they said.
For now, the most pressing concern stemmed from a radiation leak and explosion at the No. 1 reactor of the Fukushima Daiichi Nuclear Power Station on Saturday. Officials were forced to flood the overheating reactor with seawater to avoid a nuclear meltdown.
By Sunday officials were forced to take steps at another reactor — No. 3 — to avert a nuclear meltdown after a critical failure of their cooling systems briefly exposed fuel rods — a dangerous state that could lead to meltdown.
On Sunday morning, officials injected water and boric acid into the second reactor and released radioactive vapor to ease pressure, said Yukio Edano, the chief cabinet secretary. The reactor’s fuel rods had become exposed, he said, which called for the extraordinary measures.

13.50 Instructions are being giving for people living within the 20km radius around Fukushima to be evacuated, totally 210,000 people. (via NHK t.v)
13.48 Japan Newbie has published a list of useful Japanese vocabulary related to the earthquake:
13.46 Latest figures: over 1600 people dead (via NHK t.v).
13.41 Latest figures on TBS: Over 2700 dead or missing.
13.38 Mutantfrog has published an article detailing who can NOT give blood in Japan Useful reading.
13.30 150 SDF troops along with water tanks and pumps have been sent to reactor 2 at Fukushima nuclear power plant ready to start work releasing the radioactive steam and cooling the reactor core (it has not yet been decided when). Problems have been reported at the second reactor since this morning. Due to the loss of the first reactor yesterday and the continuing problems, controlled blackouts are being predicted in order to deal with the lack of power. (via TBS tv)
13.00 After careful analysis, the Japan Meteological Agency has upgraded the Tohoku earth to a Moment Magnitude (Mw) of 9.0. The effects were felt 500km North-South and 200km East-West and the quake lasted around 5 minutes. There still remains a 70% risk of the highest magnitude 7 (on the Japanese scale) aftershock for up to 3 days within the 500x200km area, so people are being advised to take care.
12.50 Live Updates Resume
**End live Updates** Thanks for sticking with me again everyone. Really gotta catch up on some proper sleep now. Keep following the live updates on Twitter with other people in Japan and be vigilant – earthquakes and tsunamis are still occurring and likely to do so for some time yet. Good night!

00.21 Explanation from an alleged Nuclear Reactor Operator from Reed College about nuclear reactor cooling systems.
In response to the question How serious is the threat to the Fukushima nuclear plant? on Reddit.
Disclaimer: IAaNRO (I Am a Nuclear Reactor Operator. I work part-time at my college’s research reactor)
Short Answer: It’s unlikely. It’s been shutdown, but the core is still producing heat. It’s not impossible for it to meltdown, but the main concern right now is that the steam pressure is rising in the cooling system, to the point where the system might rupture if nothing is done.
(Note: Originally I thought it was impossible for this reactor to meltdown at this point, but I’ve since been corrected. I’ve edited my answer slightly to reflect this)
Nuclear power reactors are of two main varieties: Pressurized Water Reactors, and Boiling Water Reactors. The plant in question is a Boiling Water Reactor (BWR). BWRs work by using the core’s thermal energy to boil the cooling water into steam, and then channelling the steam in order to turn a steam turbine. After it exits the turbine, the steam is cooled in a condenser, where it turns back to water, and then is sent back into the core. The condenser requires cool water to be actively pumped through it, to keep the pipes upon which the steam condenses from becoming too hot. The water/steam that runs through the core and the turbine is referred to as the “primary cooling system”, and the water running through the condenser is the “secondary cooling system.” The primary is assumed to be contaminated (that is, it is measurably radioactive), whereas the secondary system is not, since it is isolated from the primary.
As far as I can tell, the chain of events for this particular plant went something like this:
Shortly after the quake, the reactor successfully shut down in anticipation of the tsunami. This means that no more fission is occurring in the core. A meltdown a la Chernobyl is a result of uncontrollable fission. This will not be another Chernobyl. However, just because U-235 is no longer fissioning, doesn’t mean that the core isn’t producing heat. The fission fragments (those isotopes produced as a result of the U-235 fissioning) will continue to decay through alpha, beta, or gamma emission, until stable elements at the bottom of the decay chain are reached. The decay of these fission fragments and their decay products will cause the core to continue to produce heat for some time after shutdown.
Presumably due to the fact that every reactor near the east coast of Japan was being shutdown, offsite power for the secondary cooling system was unavailable, so the power plant had to rely on onsite backup power, but the onsite power only lasted for 8 hours. After that, the secondary cooling system failed, which is what triggered the declaration of the Nuclear Emergency, and evacuation of those living within 3Km of the plant.
Since the core is continuing to produce heat, and consequently steam, the steam pressure inside the primary system is rising above normal levels. They are hesitant to bleed off steam into the containment dome, since the dome was probably damaged in the quake, but obviously bleeding off some steam is better than having the primary system rupture. Thankfully, most of the really nasty decay products have a relatively short half-life. In particular, Nitrogen-16, which gives off pretty high energy betas when it decays, has a half-life of 7.2 seconds. Therefore, releasing the steam is undesirable, but not catastrophic, and probably not even particularly hazardous. The radioactive materials in the cloud will be longer-lived decay products of hydrogen and oxygen in, and as far as I’m aware none of those are particularly active. The cloud will be dilute itself after release, which will lower the intensity of the radiation field significantly. Therefore, the total radioactivity release will be many orders of magnitude lower than that of Chernobyl or Three Mile Island.
tl;dr: Right now, the fear isn’t meltdown, it’s mainly the steam pressure. The media are definitely playing up the meltdown angle, though.
Like I said, I’m a nuclear reactor operator–if you still have questions, please ask me.

21.46 Current death toll at over 1000 people.
20.45 Edano, Chief Cabinet Secretary, briefs the public on the situation at the Fukushima nuclear power plant, reactor 1. Beginning 14.00, valves were opened to begin releasing pressure building up in the nuclear reactor. Before this, radiation amounts were increasing. At 15.36 an explosion occurred as a result of the levels of water used for cooling the reactor decreasing. This gave rises to large amounts of radioactive steam, increasing pressure. This steam had a chemical reaction with the metal-coated pipes covering the nuclear rods, producing hydrogen. The hydrogen eventually combined with oxygen to cause the explosion, damaging the surrounding concrete and steel structure. The container and nuclear core reactor itself have not been damaged, so there will be no large radiation leaks. According to Edano, the density of radiation did not increase after the explosion. At 15.29, 1015μSv/h of radiation was detected (*edit* according to other sources this is equivalent to an annual dose for a human being). The explosion then took place at 15.36. At 15.40, 860μSv/h of radiation was detected, and at 18.58, 70.5μSv/h, showing that the level of radiation was decreasing. Currently, the radiation leakage to outside has not changed much. In order to prevent any further damage or leakage Tokyo Electric Power Company (TEPCO) are to fill the reactor with seawater (something rather unprecedented) to ensure it does not reach a critical state again. These measures have been put into place as of 20.20. Residents within the 10-20km radius are not in immediate danger, but the government wanted to err on the side of caution and extend the radius in case of any further complications. Asks all citizens to react calmly and beware of false information.
20.35 Kan, Prime Minister of Japan, speaking live on television. Government making full efforts to rescue missing persons and take care of people in evacuation areas. Regarding 1st and 2nd nuclear power plant in Fukushima, the first priority is the safety of people. New development has resulted in extending the evacuation order extended to 20km radius.

19.07 Safety advice collected via Twitter:
With the 1995 Kobe earthquake, the biggest after shock occurred 3 hours after the initial quake. Prepare for those after shocks even if it appears safe now. Get some water ready and handy. Stock up some water in your bath tub or some other containers. Get some emergency food ready. Plug off unncessary outlets. Shut down gas and electricity, especially when you leave your house to evacuate or when the power is out. A fire is most likely to occur when electricity comes back. Tokyo Electricity Power Company is asking to save electricity. Keep windows open. If you live near the ocean or a river, be aware of tsunami. Here’s info on tsunami. Don’t make phone calls unless absolutely necessary in order to ensure that those in need of making emergency calls can use the lines.
Using Skype, Twitter, Facebook, and e-mail is fine.
“Dial 171, leave a message with your home number. Anyone who knows ur home number can check your safety.” (via @beerintokyo) Google Person Finder for this earthquake is available here. Get warm clothes. Be ready for potential poweroutage if it hasn’t happened to your area yet. Check where the closest evacuation center from where you are. Parks, schools, and other public places are often used as an evacuation center. If you live in Tokyo, here’s a list of evacuation centers. It’s in Japanese, though. If you are a woman, be careful for potential rapists who take advantage of this emergency situation and be with some other people. Don’t be alone.
18.58 Power outages continuing in Tohoku and most of kanto (Tokyo area). NOTE: People are advised to turn off appliances and power to their houses before evacuating – when the power returns it could cause a fire.
