En hel del positiva nyheter har dykt upp nu under kv\u00e4llen vilket ger hopp om att man kommer kunna l\u00f6sa situationen utan allvarliga utsl\u00e4pp. \u00c4nnu g\u00e5r det dock inte garantera n\u00e5got och m\u00e5nga saker kan \u00e4nnu g\u00e5 fel.

Vi f\u00e5r hoppas man inte vaknar till nya orov\u00e4ckande rubriker imorgon!<\/p>\n Reuters<\/a><\/p>\n (Reuters) – The situation at\u00a0Japan’s Fukushima Daiichi nuclear power plant was serious but “reasonably stable” Thursday with no major worsening since the day before, a senior U.N. nuclear watchdog official said.<\/em><\/p>\n “It hasn’t got worse, which is positive,” Graham Andrew of the International Atomic Energy Agency (IAEA) said. “The situation remains very serious but there has been no significant worsening since yesterday.”<\/em><\/p>\n But Andrew, a senior aide to IAEA Director General Yukiya Amano, cautioned at a news conference: “It is still possible that it could get worse.”<\/em><\/p>\n Despite the unfolding crisis in Japan, Andrew said the nuclear industry in general had a “very good safety record,” even though the risks could not be reduced to zero.<\/em><\/p>\n “As of today I’m not aware that anyone has died from this accident. That is not to seem complacent, we’re far from that.”<\/em><\/p>\n Japanese military helicopters and fire trucks poured water on an overheating nuclear facility Thursday and the plant operator said electricity to part of the crippled complex could be restored in a desperate bid to avert catastrophe.<\/em><\/p>\n Andrew said the situation at the Fukushima Daiichi plant’s reactors 1, 2 and 3 — whose cores he said had suffered damage — appeared to be relatively stable with seawater injected into all three units to cool them.<\/em><\/p>\n But the unit 4 reactor in particular remained a “a major safety concern, he said, adding that no information was available on the water level in the spent fuel pond.<\/em><\/p>\n “The water levels in the reactor pressure vessels of reactors 5 and 6 have been declining,” he added.<\/em><\/p>\n The top U.S. nuclear regulator earlier said the cooling pool for spent fuel rods at reactor No.4 may have run dry and another was leaking and that radiation levels around the cooling pool were extremely high.<\/em><\/p>\n “UNFAIR” NUCLEAR CRITICISM<\/em><\/p>\n Workers have been trying to connect a 1-km (0.6-mile) long power cable from the main grid to restart water pumps to cool reactor No. 2, which does not house spent fuel rods considered the biggest risk of spewing radioactivity into the atmosphere.<\/em><\/p>\n The IAEA — which is tasked with fostering the safe use of atomic energy — said in a statement issued after Andrew’s news conference that Japan had informed it that engineers were able to lay the power cable to the No.2 unit.<\/em><\/p>\n “They plan to reconnect power to unit 2 once the spraying of water on the unit 3 reactor building is completed,” it said.<\/em><\/p>\n Andrew said the IAEA was regularly receiving radiation dose rate information from 47 Japanese cities and that there had been no significant change in levels in Tokyo since Wednesday.<\/em><\/p>\n Uppdatering 21:05<\/strong><\/p>\n Lite mer fr\u00e5n Reuters<\/a> om kabeln.<\/p>\n (Reuters) –\u00a0Japan<\/a>ese engineers worked through the night to lay a 1.5 km (one mile) electricity cable to a crippled nuclear power plant in the hope of restarting pumps desperately needed to pour cold water on overheating fuel rods and avert a catastrophe.<\/em><\/p>\n Officials could not say when the cable might be connected, but said work would stop on Friday morning to allow helicopters and fire trucks to resume pouring water on the Daiichi plant, about 240 km (150 miles) north of Tokyo.<\/em><\/p>\n “Preparatory work has so far not progressed as fast as we had hoped,” an official of plant operator Tokyo Electric Power Co (TEPCO) told a news briefing, adding that a cold snap was hampering the effort.<\/em><\/p>\n Washington and other foreign capitals have expressed growing alarm about radiation leaking from the plant, severely damaged by a magnitude 9.0 earthquake and tsunami a week ago that triggered a series of destructive explosions which compromised the nuclear reactors and spent fuel storage tanks.<\/em><\/p>\n Yukiya Amano, head of the Vienna-based International Atomic Energy Agency (IAEA), was due back in his homeland later on Friday with an international team of experts after earlier complaining about a lack of information from Japanese authorities on the crisis.<\/em><\/p>\n Even if TEPCO manages to connect the power, it is not clear the pumps will work as they may have been damaged by the natural disaster or subsequent explosions. Work has been slowed by the need to frequently monitor radiation levels to protect workers.<\/em><\/p>\n U.S. officials took pains not to criticize Japan’s government, but Washington’s actions indicated a divide with its close ally about the perilousness of the world’s worst nuclear accident since the Chernobyl disaster in 1986.<\/em><\/p>\n Uppdatering 19:32<\/strong><\/p>\n IAEA konfirmerar<\/a> att kabeln \u00e4r dragen till reaktorn nummer 2. Det som \u00e5terst\u00e5r \u00e4r allts\u00e5 att koppla in den, vilket \u00e4r ett jobb som man kan f\u00f6rmoda p\u00e5g\u00e5r just nu.<\/p>\n (Reuters) – Japan has told the U.N. nuclear watchdog that engineers were able to lay an external grid power cable to the No.2 unit of the disaster-hit Fukushima nuclear power plant, the Vienna-based agancy said on Thursday.<\/em><\/p>\n “They plan to reconnect power to unit 2 once the spraying of water on the unit 3 reactor building is completed,” the International Atomic Energy Agency (IAEA) said in a statement.<\/em><\/p>\n It said spraying of the No.3 unit was temporarily stopped at 1109 GMT.<\/em><\/p>\n Workers in Japan have been trying on Thursday to connect a 1-km (0.6-mile) long power cable from the main grid to restart water pumps to cool reactor No. 2.<\/em><\/p>\n Uppdatering 19:23<\/strong><\/p>\n NEI har uppdaterat sin uppf\u00f6ljning<\/a> av olyckan. Den \u00e4r tre timmar gammal vid skrivandets stund.<\/p>\n Det l\u00e5ter v\u00e4ldigt uppmuntrande! Bass\u00e4ngen i 4an \u00e4r intakt. Inneslutningen \u00e4r kanske intakt p\u00e5 2an, den nya elkabeln \u00e4r p\u00e5 g\u00e5ng och inneslutningen p\u00e5 3an \u00e4r f\u00f6rmodligen intakt. Om allt det \u00e4r sant, eller ens bara h\u00e4lften, d\u00e5 b\u00f6rjar situationen ljusna!<\/p>\n T<\/span>Reactor 1’s primary containment is believed to be intact and the reactor is in a stable condition. Seawater injection into the reactor is continuing.<\/span><\/p>\n Access problems at the site have delayed connection of a temporary cable to restore off-site electricity. The connection will provide power to the control rod drive pump, instrumentation, batteries and the control room. Power has not been available at the site since the earthquake on March 11.<\/p>\n Reactor 3 is in stable condition with seawater injection continuing. The primary containment is believed to be intact. Pressure in the containment has fluctuated due to venting of the reactor containment structure.<\/p>\n TEPCO officials say that although one side of the concrete wall of the reactor 4 fuel pool structure has collapsed, the steel liner of the pool remains intact, based on aerial photos of the reactor taken on March 17. The pool still has water providing some cooling for the fuel; however, helicopters dropped water on the reactor four times during the morning (Japan time) on March 17. Water also was sprayed at reactor 4 using high-pressure water cannons.<\/p>\n Uppdatering 14:51<\/strong><\/p>\n Uppdatering fr\u00e5n JAIF<\/a> om resultaten av att f\u00f6rs\u00f6ka f\u00e5 in vatten i 3ans bass\u00e4ng. De s\u00e4ger att de sprutat in 30 ton vatten, 30 ton \u00e4r 30 000 liter. Om man uppskattar att polen har ungef\u00e4rliga dimensioner 20*20*10 meter s\u00e5 inser man att den inneh\u00e5ller 4 miljoner lite vatten. Det handlar allts\u00e5 om mindre \u00e4n 1 % av bass\u00e4ngvolymen grovt r\u00e4knat. Den effekt denna vattensprutning kan ha haft \u00e4r att kyla ner stavarna n\u00e5got och f\u00f6rminska risken att partiklar odyl kommer spridas. Men det kr\u00e4vs betydligt mer \u00e4n s\u00e5 f\u00f6r att \u00e5terfylla bass\u00e4ngen om vattenniv\u00e5erna sjunkit. Man ser att bilarna kunde spruta 30 ton p\u00e5 24 minuter. Om de kunde st\u00e5 kvar och kontinuerligt \u00f6sa p\u00e5 med vattnet s\u00e5 tar det lite drygt 2 dagar att \u00e5terfylla en tom bass\u00e4ng(t\u00e4nk dock p\u00e5 att min uppskattning av bass\u00e4ngvolymen utan vidare kan vara fel med en faktor 2-3 jag ska f\u00f6rs\u00f6ka f\u00e5 tag p\u00e5 detaljerad information om bass\u00e4ngvolymen).<\/p>\n Status of Fukushima #1 power station as of 21:30, March 17, 2011<\/p>\n Status of Fukushima #1 power station as of 21:30, March 17, 2011\u201cOperation for filling the pool with water at unit-3\u201dNHK news reported on the operations conducted today for filling the pool withwater at unit-3 as follows:Water level is low at the spent fuel pools of unit-3. Considering possibility ofdamage to fuel rods in the pool outside the containment vessel, operation forfilling the pool with water were conducted three times.* 1st operationJapan Self-Defense Forces dropped 4 huge buckets of seawater from helicoptersin this morning. Lead plates were installed at the bottom of the helicopters toshield radiation and crew members wore radiation protection suits.* 2nd operationThe National Police Agency tried to pour water from the ground with pumpertruck in the evening. However, they were not able to come close because of highradiation and water did not reach the pool.* 3rd operationJapan Self-Defense Forces poured 30 tons of water from the ground with 5special pumper trucks from 19:45 to 20:09. Because these trucks are special, theywere able to do this operation without getting off the trucks. Effect of thisoperation is under evaluation.<\/p>\n Uppdatering 14:25<\/strong><\/p>\n \u00c4nnu en statusuppdatering fr\u00e5n JAIF<\/a><\/p>\n <\/a>Lite positiva grejer. I 2ans reaktor, den d\u00e4r de tidigare\u00a0officiellt\u00a0uppskattar st\u00f6rst h\u00e4rdskador (\u00e4ven om man inofficiellt kan l\u00e4sa mellan raderna att h\u00e4rden i 1an och 3an \u00e4r sm\u00e4lt), har man nu lyckats f\u00e5 upp vattenniv\u00e5n \u00f6ver halva h\u00e4rden. Det \u00e4r f\u00f6rst\u00e5s oklart om det finns n\u00e5tt kvar av \u00f6vre halvan eller om det ligger som en h\u00f6g p\u00e5 botten av tanken. Hur som helst verkar de allts\u00e5 f\u00e5 b\u00e4ttre inf\u00f6rsel av vatten till den h\u00e4rden vilket aldrig \u00e4r fel.<\/p>\n Att inneslutningstrycket \u00e4r ok\u00e4nt p\u00e5 1ans inneslutning l\u00e5ter d\u00e4remot v\u00e4ldigt allvarligt.<\/p>\n De anger ingen ny str\u00e5ldos vid gr\u00e4nsen av omr\u00e5det utan skriver bara samma v\u00e4rde som de m\u00e4tt f\u00f6r m\u00e5nga timmar sedan.<\/p>\n L\u00e4get f\u00f6r reaktorerna \u00e4r nog i stort sett of\u00f6r\u00e4ndrad. L\u00e4get med 3ans bass\u00e4ng verkar n\u00e5got f\u00f6rb\u00e4ttrad d\u00e5 man f\u00e5tt dit lite vatten, 4ans bass\u00e4ng \u00e4r of\u00f6r\u00e4ndrad.<\/p>\n Uppdatering 10:45<\/strong><\/p>\n Nyheterna g\u00e5r p\u00e5 sparl\u00e5ga… inte mycket ny information som kommer ifr\u00e5n Fukushima I just nu ut\u00f6ver statusmatrisen nedan. Senaste budet var att vattenbombningar p\u00e5g\u00e5r men att man oftast missar m\u00e5let. Inga nya besked om kraftledningen som skall \u00e5terst\u00e4lla huvudpumparna… bara att arbetet p\u00e5g\u00e5r och att man “snart” \u00e4r klara.<\/p>\n Uppdatering 10:24<\/strong><\/p>\n JAIF<\/a> har sl\u00e4ppt en ny statusuppdatering. Status f\u00f6r reaktorerna f\u00f6r 2 timmar sen. Tyv\u00e4r ser vi en gradvis f\u00f6rs\u00e4mring av l\u00e4get. I reaktorn 3 s\u00e5 har de nu fyllt upp inneslutningen med havsvatten, det betyder med stor s\u00e4kerhet att de misst\u00e4nker att en signifikant del av h\u00e4rden har sm\u00e4lt. N\u00e4r h\u00e4rden sm\u00e4lten l\u00e4gger den sig i botten p\u00e5 reaktortanken och det blir d\u00e5 viktigt att kyla tanken fr\u00e5n utsidan samtidigt som man pumpar vatten inuti h\u00e4rden f\u00f6r att p\u00e5 alla s\u00e4tt f\u00f6rhindra att sm\u00e4ltan kan sm\u00e4lta sig igenom tanken och ramla ut i inneslutningen. Vid reaktor 1 har man haft inneslutningen fylld med vatten i flera dagar nu vilket antyder att om h\u00e4rden h\u00e5ller p\u00e5 att sm\u00e4lta igenom tanken s\u00e5 g\u00e5r det iallafall l\u00e5ngsamt. Eller s\u00e5 har h\u00e4rden\u00a0kristalliserats\u00a0p\u00e5 botten och h\u00e5lls tillr\u00e4ckligt kyld. Det \u00e4r om\u00f6jligt att s\u00e4ga.<\/p>\n Det positiva \u00e4r att de verkar ha kvar vatten i br\u00e4nslebass\u00e4ngerna i 3an och 4an. L\u00e4get \u00e4r sv\u00e5rt eftersom vattenniv\u00e5erna \u00e4r l\u00e5ga, men de har \u00e5tminstone vatten d\u00e4r. Str\u00e5ldoserna p\u00e5 omr\u00e5det ligger p\u00e5 niv\u00e5n 0.6 mSv per timme. Inte omedelbart farligt, en typisk Svensk \u00e5rsdos p\u00e5 8-10 timmar.<\/p>\n Uppdatering 07:00<\/strong><\/p>\n F\u00e5 nyheter har kommit fram under natten. Vattenbombning p\u00e5g\u00e5r.<\/p>\n
\nReactor 2 is in stable condition with seawater injection continuing.
