Nuclear meltdown - Fukushima Daiichi

Piksi se vraca. Ipak radijacija je to.

Gledam danas malo CNN i prikazuju jedan supermarket u jednom od razrušenih mesta. U supermarketu sve razbacano, staklo na sve strane popucalo, a ljudi stoje u dugačkom redu i čekaju da kupe svoje artikle. Negde drugde bi se ljudi odavno pobili oko svega toga, i svako bi odvukao koliko može da nosi. Zaista neverovatan narod.

U srbiji kradu patike i prevrcu kontejnere.

Zato i volim japance, sto su neverovatni. Pre bih rekao da smo mi neverovatni
 
Jeste, svi ostali bi se potukli u supermarketu, a mi srbi ne, nama su samo patike interesante :d
 
@rAMA
Gde negde drugde? Reci lepo u Srbiji, Libanu..... ;)

Greske koje su uticale na tragican razvoj situacije u Fukushima Daiichi.
Costly missteps at Fukushima Daiichi

Backup generators susceptible to tsunami: The plant designer prepared well for an earthquake, but backup generators and fuel tanks were located on lower ground, leaving them vulnerable to a tsunami that might be expected to occur from a massive offshore temblor.

Lack of adequate battery power: When some diesel generators needed to cool the reactor core failed, the crews resorted to battery powered pumps. But the batteries had an eight-hour lifespan, and the plant was not equipped with enough extras to maintain cooling efforts.

Poor communication: The Japanese head of the International Atomic Energy Agency complained of not getting timely or detailed information, as have domestic news media. As a result, the population is uncertain and panicky at the potential threat.

Running out of fuel: Water levels in No. 2 reactor fell after the diesel pump ran out of fuel and workers did not notice quickly enough.

Checking the gauges: Air pressure inside No. 2 reactor rose suddenly when the air flow gauge was accidentally turned off. That blocked the flow of water into the reactor, leading to the water level dropping and the exposure of the fuel rods.

2004 je u TEPCO bio skandal u vezi friziranja izvestaja o bezbednosti njihovih postrojenja.

Ovo je dokaz (pored ČErnobila) da je ljudska greška, greška projektanta ili operatora uvek moguća i koliko se kod vodilo računa o njoj ona će kad tad nastupiti jer je zbog čovekove prirode neizbežna i zato je treba uvek uračunati u bilo koji projekat a najbolje je reći neka hvala nećemo nuklearke
 
Ovo nije sigurna informacija, vidim neke komentare da su se radnici vratili u NE.

Japan suspends work at stricken nuclear plant

FUKUSHIMA, Japan – Japan suspended operations to keep its stricken nuclear plant from melting down Wednesday after surging radiation made it too dangerous to stay.

Chief Cabinet Secretary Yukio Edano said the workers dousing the reactors in a frantic effort to cool them needed to withdraw.

"The workers cannot carry out even minimal work at the plant now," Edano said. "Because of the radiation risk we are on standby."

The nuclear crisis has triggered international alarm and partly overshadowed the human tragedy caused by Friday's earthquake and tsunami, which pulverized Japan's northeastern coastline, killing an estimated 10,000 people and severely damaging the nuclear plant.

Since then, authorities have tried frantically to avert an environmental catastrophe at the Fukushima Dai-ichi complex in northeastern Japan, 140 miles (220 kilometers) north of Tokyo.

Edano said the government expects to ask the U.S. military for help. He did not elaborate. He said the government is still considering whether and how to take up the various offers of help from other countries.

The surge in radiation was apparently the result of a Tuesday fire in the complex's Unit 4 reactor, according to officials with Japan's nuclear safety agency. That blast is thought to have damaged the reactor's suppression chamber, a water-filled pipe outside the nuclear core that is part of the emergency cooling system.

Officials had originally planned use helicopters and fire trucks to spray water in a desperate effort to prevent further radiation leaks and to cool down the reactors.

"It's not so simple that everything will be resolved by pouring in water. We are trying to avoid creating other problems," Edano said.

"We are actually supplying water from the ground, but supplying water from above involves pumping lots of water and that involves risk. We also have to consider the safety of the helicopters above," he said.

A U.S. nuclear expert said he feared the worst.

"It's more of a surrender," said David Lochbaum, a nuclear engineer who now heads the nuclear safety program for the Union of Concerned Scientists, an activist group. "It's not like you wait 10 days and the radiation goes away. In that 10 days things are going to get worse."

"It's basically a sign that there's nothing left to do but throw in the towel," Lochbaum said.

Prelaze na hladjenje i sa helikopterima, ovo sve vise podseca na cernobilj, valjda nece i biti tako.
 
Mogli bi da ponudimo trajni smestaj njihovim izbeglicama da dobijemo infuziju Japanske pameti i marljivosti,korist bi bila obostrana.
 
Da li postoje negde na netu slike zgrade iznutra nekog od Fukushima reaktora, sad u toku radova?

Nebitno, nego čisto iz radoznalosti bih da bacim pogled ako postoji neka fotka izbliza.

Nadam se da ce sve proci bez daljih problema. Jaki su oni. Jedino imaju onog guvernera tokija, ******a koji je jednom izjavio da je ovo sto se desilo japanu bozja kazna jer su moralno posrnuli. A tip je svojevremeno bio pisac silovateljskih romana. Valjda je mislio da je on moralno posrnuo. Danas se izvinjavao pred kamerama zbog te izjave. ******.

Па јесу духовно и разне друге начине пропали (самоубиства говоре о томе), и неко може да тумачи то као казна богова, јер су исте напустили... Наравно не кажем да је то мој став. Само надам се да ће после ове катастрофе и када крену у обнову, повратити своје достојанство и повратити независност.

Trenutno pricaju o radijaciji, prilicno zanimljivo ;)
Malo pre je bio ukljucen studio gde su doneli makete reaktora i okoline. Kakvi su japanci moze se videti iz toga koliko su detaljisali sa modelom reaktora, tacno se vidi u kakvom (losem) stanju su reaktori :zgran:
Samo jedan je citav.

Obavezno pogledajte.
 
bog me napustio... za trenutak je otisao u wc da vidi gde to kaplje i jel pustio vodu za sobom :/

kakve gluposti (al dobro,necemo offtopic,podrazumeva se da pametan covek zna sta je verovatnije)

Edano said the skeleton crew of about 50 workers still struggling to pump seawater onto the fuel rods at all six of the plant's reactors had been removed from the plant for their safety, but that radiation levels appeared to be dropping by midday. He said later that monitoring showed radiation levels within 30 kilometers of the plant were not so high as to pose a threat to human health.

Even when they are not in use, the nuclear fuel rods remain very hot for weeks or months. Unless they are kept cool with a steady supply of water, their outer casings can melt away releasing radiation into the air.

jel istina ovo da mesecima ostaje vrele cevi? cak iako nije u pogonu :/

Da, ostaju vrele. Čak i kada su potpuno istrošene, one još neko vreme generišu toplotu, koja je "mala", ali ipak dovoljna da napravi sr4nje ako se ne haldi. Nivo radijacije je postao previše visok jer su potrošene fuel rods, kao i one u reaktoru, bile direktno izložene u vazduhu jer je nivo vode opao, što je nateralo radnike da se povuku. Plan je da se vodenim topovima iz daljine ubacije voda kako bi se ohladio bazen potrošenih fuel rods, tj. kako bi se sprečilo njihovo topljenje i dalje eksplozije i curenje radioaktivne materije na sve strane.

Cak i da se sve zavrsi kako valja, bice potrebno hladiti sve to bar naredne dve godine ne bi li mogli da pridju reaktorima i pociste problem.
 
Bilo koji nastavak ukljucivanja religije u ovo bice (brutalno) moderisan. Hvala.
 
^ Sta ti imas protiv religije? :D :D :d
