So instead of just past midnight on March 13, 2011, the water may have stopped 6 hours earlier, on the night of March 12, 2011, a few hours after the Reactor 1 building blew up in an hydrogen explosion (which may have happened on the 4th floor instead of the 5th, top floor).
From Yomiuri Shinbun (3/24/2013):
It looks like the nuclear accident is so behind them in Japan, rat or no rat. Ministry of Health and Labor announced that the radioactivity testing for food items will be scaled down significantly, by exempting 34 items from testing.
That's 25% of food items that have been regularly tested since the start of the Fukushima I Nuclear Power Plant accident.
They have been testing only 132 food items to begin with.
What's puzzling is that certain fruits that have consistently been found with elevated amounts (if not exceeding the safety standard of 100 Bq/kg) of radioactive cesium are going to be exempted - peaches, apples, and pears.

#Fukushima I Nuke Plant Reactor 3: Those Blank 6 Hours of No Water Injection on March 13, 2011 May Have Been 12 Hours Instead, TEPCO's New Analysis Shows
So instead of just past midnight on March 13, 2011, the water may have stopped 6 hours earlier, on the night of March 12, 2011, a few hours after the Reactor 1 building blew up in an hydrogen explosion (which may have happened on the 4th floor instead of the 5th, top floor).
From Yomiuri Shinbun (3/24/2013):
３号機注水、１２時間途絶か…解析やり直しへ
Water injection into Reactor 3 may have stopped for 12 hours, analysis to be redone
２０１１年３月の東京電力福島第一原子力発電所事故の際、３号機の原子炉への冷却水注入が途絶えた「注水の空白」は約１２時間に及んでいた可能性が、東電などの調査で明らかになった。
It has been revealed by analysis by TEPCO and others that the blank in water injection into the Reactor 3 RPV may have been 12 hours in March 2011 in the Fukushima I Nuclear Power Plant accident.
３号機の「注水の空白」は従来、３月１３日未明から６時間半とされていたが、当時の運転員が記録した水位データが昨秋、新たに判明し、最大で約６時間早い１２日夜には注水が止まっていた恐れが出てきた。
The blank in water injection into Reactor 3 is said to have been for 6.5 hours starting in the early hours of March 13, 2011. However, the data on water levels recorded by the operator at that time surfaced in fall last year, which shows the water injection may have stopped max 6 hours earlier, on the night on March 12, 2011.
東電はこれまでの解析で、３号機の炉心溶融は１３日朝に始まったとしてきたが、注水が早く停止したという新しい条件に基づき、解析をやり直す方針。その結果次第では、放射性物質の拡散状況を推定する前提条件が変わる可能性もある。東電の調査に関して、政府の事故調査・検証委員会は昨年７月の最終報告書で「事故の解明は不十分で、検証すべき論点やデータが残っている」と指摘していた。
TEPCO's current analysis shows the core melt of Reactor 3 started in the morning of March 13, 2011. The company plans to redo the analysis based on the new condition that the water injection may have stopped earlier.Depending on the result of the new analysis, it is possible that the conditions to estimate the dispersion of radioactive materials will change. Regarding TEPCO's investigation [of the accident], the independent accident investigation commission set up by the Cabinet Office pointed out in the final report issued in July last year that "the investigation of the accident is not enough, and there are issues and data still to be studied".
All I can say is that the investigation commission is correct.
Even though there was no MOX fuel in the Reactor 3 Spent Fuel Pool at the time of the accident, it was in the Reactor Pressure Vessel, being used in generating power.
Back in May 26, 2011, Mainichi English reported that TEPCO admitted the pipe connected to the High Pressure Coolant Injection system (HPCI) for the Reactor 3 probably broke during the earthquake (see my post on that day).
On March 13, 2011 at 12:55PM, TEPCO discovered that 1.9 meter of the fuel rods in Reactor 3 were exposed, and at 1:12PM they started to pour seawater into the RPV (see my post that day). Well, that 1.9 meter exposure was false, in retrospect.
Earlier that day, the emergency battery power ran out for the High Pressure Coolant Injection System, and the system shut itself down at 2:44AM. At 4:15AM, the fuel rods started to get exposed as the water in the container started to boil and water level started to go down. Nuclear emergency was issued on 6AM. (See my post from that day.)
Now, TEPCO is saying the water may have stopped much earlier than 2:44AM on March 13, 2011 when the HPCI stopped. Or are they saying the HPCI itself stopped much earlier? Or are they saying water ran out (as the pipe to the HPCI had been broken in the earthquake) before the HPCI stopped?
I'm looking forward to TEPCO's new and improved analysis. I want to know the true timeline of events, which is clear as mud after more than two years since the start of the nuclear accident.
Whether you like it or not, TEPCO remains unfortunately the only source of information when it comes to Fukushima I Nuke Plant.

#Radioactive Japan: Number of Food Items to Be Tested for Radiation Will Be Reduced by 25%, First Major Revision Since the Start of Nuclear Accident
It looks like the nuclear accident is so behind them in Japan, rat or no rat. Ministry of Health and Labor announced that the radioactivity testing for food items will be scaled down significantly, by exempting 34 items from testing.
That's 25% of food items that have been regularly tested since the start of the Fukushima I Nuclear Power Plant accident.
They have been testing only 132 food items to begin with.
What's puzzling is that certain fruits that have consistently been found with elevated amounts (if not exceeding the safety standard of 100 Bq/kg) of radioactive cesium are going to be exempted - peaches, apples, and pears.
From Kyodo News (3/19/2013):
食品のセシウム検査縮小へ 厚労省
Testing for radioactive cesium in food to be scaled down, Ministry of Health and Labor says
政府は１９日、自治体が実施している食品の放射性セシウム検査で、葉もの野菜や、果実の一部とイワシなど魚類の一部などを４月以降、原則として重点検査対象から除外すると発表した。厚生労働省によると、対象食品数（品目・類）は１３２から９８に減る。重点検査の大幅見直しは初めて。
On March 19, the national government announced that certain leafy vegetables, fruits, and certain kinds of fish will be exempt from the tests conducted by the municipalities for radioactive cesium, starting April. The number of food items to be tested will be reduced from the current 132 to 98. It is the first time that the radiation test for food has been significantly revised.
同省は「検査で放射性セシウムが検出されない食品が多くなっているため」としている。
The reason given by the ministry is that radioactive cesium is not detected any more in increasing number of food items.
具体的には、野菜類ではホウレンソウやレタス、キャベツ、ダイコン、ジャガイモなど、果実ではモモ、リンゴ、ナシなど、魚類ではコウナゴ（イカナゴの稚魚）、イワシ、サバ、ブリなどが除外される。
For example, the items to be excluded from the testing are spinach, lettuce, cabbage, daikon, potatoes and others for the vegetables, peach, apple, pear and others for the fruits, young lancefish, sardine, mackerel, yellowtail and others for the fish.
Well, as you know, peaches, apples, pears and persimmons from Fukushima will be sold to Thailand as "gourmet fruits" for the rich. JETRO just announced that Malaysia will no longer require the radiation test certificates for the food items from Japan. Rich Malaysians will get to eat those "gourmet fruits", too.
Information at the website of Ministry of Health and Labor is as clear as mud. You can't readily tell which vegetables, fruits and fish have been exempted by the Nuclear Disaster Response Headquarters. You have to know exactly what they have been testing (132 items) to know what will be exempt, as the ministry's press release only confirms what are still to be tested.
