Inte s\u00e5 mycket nytt. NISA (japanska str\u00e5lskyddsmyndigheten) har inte sl\u00e4ppt n\u00e5gon statusuppdatering, inte heller TEPCO eller JAIF. \u00a0Toshiba och Hitatchi<\/a> har skickat ingenj\u00f6rer f\u00f6r att hj\u00e4lpa till vid Fukushima.<\/p>\n

The company said dozens of its engineers are set to instruct workers at the plant operated by TEPCO about the usage of pumps to inject water into the plant’s reactors, adding the firm has already sent motors to activate the pumps at the facility.<\/em><\/p>\n

I en tidigare notis som jag inte har l\u00e4nk till s\u00e5 stod det att arbete var p\u00e5 v\u00e4g att \u00e5terst\u00e4lla elektricitet till verket, det vore fenomenalt bra ifall man lyckas med det. Kyodo har som vanligt en bra sammanfattande artikel<\/a> \u00f6ver l\u00e4get. \u00a0Vi v\u00e4ntar \u00e4nnu med andan i halsen allts\u00e5.<\/p>\n

Enligt Reuters!!!<\/a><\/p>\n

TEPCO says the water level at Fukushima Daiichi no.2 reactor is recovering smoothly<\/p>\n

Uppdatering 14:52<\/strong><\/p>\n

Det \u00e4r v\u00e4ldigt olustigt att TEPCO inte n\u00e4mner ett ord om br\u00e4nslebass\u00e4ngerna i reaktorbyggnad 1 och 3. Vi vet att n\u00e5tt h\u00e4nder i bass\u00e4ngen i reaktorbyggnad 4. Av n\u00e5gon anledning brann det d\u00e4r, men olika k\u00e4llor p\u00e5st\u00e5r olika saker. Vissa s\u00e4ger att br\u00e4nslet brann, vissa s\u00e4ger att det var n\u00e5got annat. Vatten kan ju som vi vet inte brinna, s\u00e5 vad var det is\u00e5fall. Om br\u00e4nslet brunnit s\u00e5 innebar det att niv\u00e5n i bass\u00e4ngen sjunkit \u00f6ver 10 meter och exponerat br\u00e4nsleknippena f\u00f6r luften under nog l\u00e5ng tid f\u00f6r att de ska bli varma nog att kapslingen ska b\u00f6rja brinna. Men det verkar inte logiskt d\u00e5 vattenfl\u00f6det som kr\u00e4vs f\u00f6r att h\u00e5lla upp vattenniv\u00e5n i bass\u00e4ngen gentemot den lilla effekten knippena producerar \u00e4r v\u00e4ldigt l\u00e5g.<\/p>\n

Just nu \u00e4r det flera mysterier som p\u00e5g\u00e5r, men tystnaden runt bass\u00e4ngerna i 1an och 3an \u00e4r inte betryggande.<\/p>\n

Senaste JAIF uppdateringen<\/a> av l\u00e4get, tidsst\u00e4mplad till ungef\u00e4r 3 timmar sen. Det s\u00e4gs att kylningen av reaktorer 1, 2 och 3 \u00e4r stabil eftersom trycket bibeh\u00e5lls inuti. Oklart om de menar inuti reaktortankarna eller inuti inneslutningarna. Om det \u00e4r inneslutningarna s\u00e5 l\u00e5ter det lovande med tanken p\u00e5 brottet i 2ans inneslutning. Om man lyckas bibeh\u00e5lla tryck s\u00e5 inneb\u00e4r det att brottet inte kan vara j\u00e4tte stort. Dock f\u00f6r tidigt f\u00f6r att s\u00e4ga n\u00e5got s\u00e4kert, vi h\u00e5ller alla andan!<\/p>\n

(NISA) or the chief cabinet secretary.<\/div>\n
\u30fbSeawater injection operation is going on at unit-1, unit-2 and unit-3. NISA<\/strong><\/div>\n
presumed that these reactors are cooled in a stable manner through this<\/strong><\/div>\n
operation based on the fact that pressure inside is maintained.<\/strong><\/div>\n

\n<\/strong><\/div>\n
\u30fbFire at unit-4 was burned out naturally around 11:00. NISA expressed it\u2019s<\/strong><\/div>\n
intention to pour water into the pool immediately since fuel rods in the pool are<\/strong><\/div>\n
being heated.<\/strong><\/div>\n

\n<\/strong><\/div>\n
\u30fbNISA described the possibility of damage to the suppression pool, which has<\/strong><\/div>\n
function of decreasing pressure inside the containment vessel.<\/strong><\/div>\n

\n<\/strong><\/div>\n
\u30fbThe chief cabinet secretary said that water temperature is steady increased in<\/strong><\/div>\n

BBC Flash news : Japan Government confirms radiation leak at Fukushima nuclear plants. Asian countries should take necessary precautions. If rain comes, remain indoors first 24 hours. Close doors and windows. Swab neck skin with betadine where thyroid area is, radiation hits thyroid first. Take extra precautions. Radiation may hit Philippine at around 4 pm today. If it rains today or in the next few days in Hong Kong. Do not go under the rain. If you get caught out, use an umbrella or raincoat, even if it is only a drizzle. Radioactive particles, which may cause burns, alopecia or even cancer, may be in the rain.<\/p>\n

Fukushima Daiichi Nuclear Power Plant Update<\/strong><\/p>\n

<\/strong><\/p>\n

Radiation Dose Rates Observed at the Site<\/strong><\/p>\n

The Japanese authorities have informed the IAEA that the following radiation dose rates have been observed on site at the main gate of the Fukushima Daiichi Nuclear Power Plant.<\/p>\n

At 00:00 UTC on 15 March a dose rate of 11.9 millisieverts (mSv) per hour was observed. Six hours later, at 06:00 UTC on 15 March a dose rate of 0.6 millisieverts (mSv) per hour was observed.<\/p>\n

These observations indicate that the level of radioactivity has been decreasing at the site.<\/p>\n

As reported earlier, a 400 millisieverts (mSv) per hour radiation dose observed at Fukushima Daiichi occurred between units 3 and 4. This is a high dose-level value, but it is a local value at a single location and at a certain point in time. The IAEA continues to confirm the evolution and value of this dose rate. It should be noted that because of this detected value, non-indispensible staff was evacuated from the plant, in line with the Emergency Response Plan, and that the population around the plant is already evacuated.<\/p>\n

About 150 persons from populations around the Daiichi site have received monitoring for radiation levels. The results of measurements on some of these people have been reported and measures to decontaminate 23 of them have been taken. The IAEA will continue to monitor these developments.<\/p>\n

Evacuation of the population from the 20 kilometre zone is continuing. The Japanese have asked that residents out to a 30 km radius to take shelter indoors. Japanese authorities have distributed iodine tablets to the evacuation centres but no decision has yet been taken on their administration.<\/p>\n

Background on Radiation<\/strong><\/p>\n

<\/strong><\/p>\n

A person\u2019s radiation exposure due to all natural sources amounts on average to about 2.4 millisievert (mSv) per year. A sievert (Sv) is a unit of effective dose of radiation. Depending on geographical location, this figure can vary by several hundred percent.<\/p>\n

Since one sievert is a large quantity, radiation doses are typically expressed in millisievert (mSv) or microsievert (\u00b5Sv), which is one-thousandth or one millionth of a sievert. For example, one chest X-ray will give about 0.1 mSv of radiation dose.<\/p>\n

Chief Cabinet Secretary Yukio Edano tells reporters radiation levels at the Fukushima Daiichi complex have fallen dramatically to 596.4 microsieverts per hour<\/strong>. That level is almost 700 times less than the levels reported in the morning, after two fresh blasts at the complex.<\/div>\n

BREAKING NEWS: Remains to be seen if water smoothly injected into No. 2 reactor: Edano<\/p>\n

Uppdatering 08:22<\/strong><\/p>\n

Just nu kommer ingen vettig information ut \u00f6verhuvudtaget. Det vi vet \u00e4r att under natten skedde n\u00e5gon slags explosion som f\u00f6rmodligen skadade pressure supression pool, ringen i botten p\u00e5 reaktorn p\u00e5 bilden jag bifogat. Detta \u00e4r v\u00e4ldigt allvarligt d\u00e5 det \u00e4r en del av inneslutningen och d\u00e4rmed s\u00e5 finns det en v\u00e4g direkt ut till omgivningen ifall reaktortanken, den st\u00e5ltank som h\u00e5ller h\u00e4rden, havererar. Det inneb\u00e4r ocks\u00e5 att det kan bli sv\u00e5rt att h\u00e5lla inneslutningen och reaktortanken t\u00e4ckt med vatten. TEPCO ger inga detaljer \u00f6verhuvudtaget om orsaken till explosionen eller nuvarande statusen.<\/p>\n

Ungef\u00e4r samtidigt som nyheten om explosionen d\u00f6k upp i japansk media s\u00e5\u00a0meddelade\u00a0man ocks\u00e5 att det brinner i reaktorbyggnaden runt reaktor nummer 4. Reaktor 4 \u00e4r en av de 3 reaktorer som redan var nedst\u00e4ngda f\u00f6re tsunamin och f\u00f6re branden har det inte funnits n\u00e5gon antydan till att TEPCO skulle haft problem d\u00e4r eller att kylningen inte fungerar. I samband med branden uppm\u00e4ttes v\u00e4ldigt h\u00f6ga aktivitetsniv\u00e5er<\/a> runt reaktor nummer 3, upp mot 400 mSv.<\/p>\n

Eftersom inget nytt rapporterats om inneslutningen p\u00e5 3an s\u00e5 kan man bara f\u00f6rmoda att det n\u00e5got h\u00e4nder med br\u00e4nslebass\u00e4ngen i 3an. Br\u00e4nslebass\u00e4ngen \u00e4r en bass\u00e4ng d\u00e4r man l\u00e5ter anv\u00e4nt br\u00e4nsle ligga innan det skickas vidare till en l\u00e4ngre tids f\u00f6rvaring. Bass\u00e4ngerna i den typ av reaktor som finns i Fuhushima \u00e4r inte skyddad ovanifr\u00e5n och st\u00e5r d\u00e4rmed \u00f6ppen f\u00f6r v\u00e4der och vind och ingen vet hur den p\u00e5verkades av explosionen. Br\u00e4nsleknippena i bass\u00e4ngen \u00e4r inte lika heta som i reaktorn, men nog heta f\u00f6r att kunna b\u00f6rja brinna ifall de avt\u00e4cks. Med tanken p\u00e5 att det inte finns n\u00e5gon inneslutning s\u00e5 skulle en brand i bass\u00e4ngen kunna vara v\u00e4rre \u00e4n en h\u00e4rdsm\u00e4lta i h\u00e4rden.<\/p>\n

Det verkar dessv\u00e4rre nu som att TEPCO inte varit v\u00e4ldigt \u00f6ppna med den informationen som de gett ut och d\u00e4rmed gett sken om att situationen \u00e4r mer kontrollerad \u00e4n den egentligen var. M\u00e5nga stora fr\u00e5getecken finns just nu och det \u00e4r om\u00f6jligt att veta hur allvarlig situationen \u00e4r f\u00f6ren de har besvarats. Men med tanken p\u00e5 att f\u00f6rh\u00f6jda aktiviteter uppm\u00e4tts i Tokyo s\u00e5 har n\u00e5got stor och allvarligt g\u00e5tt fel.<\/p>\n
