Blast Heard At Fukushima's No.2 Reactor: Govt

TOKYO (Kyodo)--An explosion was heard early Tuesday morning at the troubled No. 2 reactor of the quake-hit Fukushima No. 1 nuclear power plant, the government said, about five hours after work resumed to inject seawater into it to prevent overheating of exposed fuel rods.

Shortly after the 6:10 a.m. incident, the radiation level exceeded the legal limit to reach 965.5 micro sievert per hour, and it is feared that the reactor's pressure-suppression system was damaged, the Nuclear and Industrial Safety Agency.

Tokyo Electric Power Co., the plant's operator, said it is evacuating workers from the plant, except for those necessary for the work to cool the reactor.

The reactor's fuel rods were fully exposed for around two and a half hours Monday evening after water levels rapidly fell, and again late Monday night although seawater was being injected, prompting the utility to open some steam valves at 1:10 a.m. in order to resume pumping seawater.

As of 3 a.m., pressure inside the reactor's pressure container had dropped and it was believed seawater had been successfully pumped in, but a rise in water levels has not been confirmed, the utility said.

Prime Minister Naoto Kan said earlier in the morning that the government and TEPCO will set up an integrated headquarters, headed by himself, to address issues at the Fukushima No. 1 plant.

With radiation levels around the facility up, TEPCO suspects the core of the No. 2 reactor has partially melted, a critical nuclear safety situation.

The development follows hydrogen blasts at both of the plant's two other reactors whose cores are also believed to have partially melted, occurring Saturday at the No. 1 reactor and Monday at the No. 3 reactor.

''A worrisome situation remains but I hope to take the lead in overcoming this crisis,'' Kan said of the nuclear power plant. ''I will take all measures so that damage will not expand.''

At the headquarters set up at the TEPCO head office, with TEPCO president and the economy, trade and industry minister serving as its deputy chiefs, Kan confronted TEPCO officials about their delay in reporting recent blasts at the plant.

The No. 2 reactor automatically shut down after the magnitude 9.0 earthquake hit the region on Friday. Its reactor cooling function was lost on Monday and water levels rapidly dropped, fully exposing fuel rods for around two and a half hours from 6:30 p.m.

Seawater was injected and water levels were increased temporarily but late Monday night they started dropping, leading to full exposure of the rods again.

At 1:10 a.m. Tuesday, TEPCO opened some steam valves and resumed work to pump seawater and was considering opening more valves, according to the company.

The International Atomic Energy Agency (IAEA) said it was “unlikely” that the accident would turn into another Chernobyl, but failed to rule it out completely.

Na verdade, disse "very unlikely"...

Aqui fica a declaração e as razões:

FUKUSHIMA 'UNLIKELY' TO BE NEW CHERNOBYL: IAEA
AFP
March 15, 2011, 7:46 am

VIENNA (AFP) - The crisis at Japan's earthquake-damaged nuclear power plant is "unlikely" to turn into a new Chernobyl, which was the world's worst nuclear accident, the UN atomic watchdog said on Monday.

"Let me say that the possibility that the development of this accident into one like Chernobyl is very unlikely," Yukiya Amano told a news conference at the headquarters of the International Atomic Energy Agency in Vienna.

The current crisis at the Fukushima nuclear plant was caused not by human error or a design fault, as in the case of Chernobyl in Ukraine in 1986, but by a "huge natural catastrophe beyond imagination," Amano said.

In addition, the reactors at Fukushima had been automatically shutdown when the earthquake hit, so "there is no chain reaction going on," the IAEA chief said.

Furthermore, the Chernobyl reactor did not have a reactor vessel, while Fukushima does "and that reactor vessel is still contained" even after two explosions there, he said.

The "design is different and the structure is different. Based on this, it is very unlikely that Fukushima would develop into an accident like Chernobyl," Amano said.

The IAEA also said it has no indication at the current time of a possible meltdown at the quake-hit nuclear reactors.

"We have no indication of fuel that is currently melting at this point," said James Lyons, director of the IAEA's Safety at Nuclear Installations division.

The current situation was "very dynamic... (but) given the information we have, we have not been told that at this point," the expert said.

Amano said that Japan has officially asked the IAEA to send a team of experts to help in the current nuclear crisis.

It had not yet been decided the exact nature of the assistance the watchdog would provide, or when, he said.

"The areas that we can provide assistance are radiation surveillance, environmental sampling, medical support, recovery of missing or misplaced radioactive sources and advice on emergency response," he said.

"It will be discussed in the coming days and weeks."

As soon as the massive earthquake hit Japan on Friday, damaging the Fukushima nuclear plant located 250 kilometres (160 miles) northeast of Tokyo, the IAEA made a formal offer of assistance to the government.

Japanese-born Amano described the 8.9-magnitude quake and the devastating tsunami it triggered as "a tragedy of cataclysmic proportions. This has been one of the greatest natural disasters of modern times, the full extent of which is still becoming clear."

The events of the last few days were "truly unprecedented," Amano continued.

"The modern infrastructure of a highly industrialized country has been dealt a devastating blow by the immense destructive power of nature. I send my deepest condolences to the people and government of Japan."

The giant nuclear plant of Fukushima was damaged by the quake, with two explosions hitting separate reactor units there.

But "the reactor vessels have held and radioactive release is limited," Amano insisted.

In Brussels, the EU's energy commissioner Guenther Oettinger called on the IAEA to convene an extraordinary meeting of member states "to take stock of the situation" in Japan.

The idea was also to "organise a coordinated response and initiate a reflection on the possible implications for nuclear safety" following Japan's nuclear emergency, Oettinger's office said.

The commissioner has called a snap meeting in Brussels on Tuesday of EU energy ministers, national nuclear safety officials and big nuclear companies to look at safety measures in Europe.

Some 150 reactors are scattered across the continent in half as many nuclear power plants -- some located in seismic areas.

Amano said he had not received Oettinger's letter, but it was not up to him to decide, but rather the IAEA member states.

"Whether we have a special meeting of member states or not, that's up to the member states to decide," he said.

But as far as he was concerned, he thought member states would find a planned daily briefing useful, which would be held starting from Tuesday, Amano said.

Também existem peritos a alegar que o acidente já tem a dimensão de Chernobyl mas que os Japoneses estão a esconder a verdade. Convém recordar que estamos em 2011 e Fukushima está sobre o olhar atento do mundo inteiro praticamente desde a primeira hora. Além disso, o Japão é um país democrático e aberto e pediu auxílio internacional. Encontram-se nas proximidades forças militares com dispositivos capazes de medir radioactividade inclusivamente (ver notícia abaixo).

No caso de Chernobyl, estavamos em 1986 e perante uma nação fechada ao mundo que escondeu o sucedido. Porém, em cerca de 24 horas os países vizinhos descobriram o que aconteceu pois detectaram a radiação anormal...

17 in U.S. Navy Treated for Contamination
By THOM SHANKER
Published: March 14, 2011

WASHINGTON — American Navy officials in Japan said early Monday that 17 military personnel who had been aboard three helicopters assisting in the earthquake relief effort had been exposed to low levels of contami

Cmdr. Jeff A. Davis, a spokesman for the American Seventh Fleet in Japan, said the Navy personnel — who apparently had flown through a radioactive plume from a damaged nuclear power plant — had been ordered to dispose of their uniforms and to undergo a decontamination scrub that had successfully removed radioactive particles.

“They received very, very low levels of contamination,” Commander Davis said in a telephone interview from Japan early Monday.

“It certainly is not cause for alarm,” he said. “It is something we have to watch very carefully and make sure we are able to monitor, and to mitigate against this environmental hazard.”

The Navy personnel aboard the three helicopters had received the equivalent of one month’s natural background radiation from the sun, rocks or soil, he said.

The helicopter crew members had landed aboard the U.S.S. Ronald Reagan, a nuclear-powered aircraft carrier whose on-board sensors had indicated that the warship, too, had been exposed to airborne contamination at very low levels. The helicopter crew members were tested individually with hand-held radiation monitors.

The carrier and its strike group were operating about 100 miles northeast of the damaged power plant at the time, but the helicopters had flown closer to assist in relief missions near Sendai, the city that bore much of the brunt of the tsunami after Friday’s earthquake.

The Ronald Reagan and other American warships have now sailed to areas where they will not be in the path of radiation carried in the wind.

“As a precautionary measure, U.S.S. Ronald Reagan and other U.S. Seventh Fleet ships conducting disaster-response operations in the area have moved out of the downwind direction from the site to assess the situation and determine what appropriate mitigating actions are necessary,” Commander David said.

But he stressed that the fleet remains “committed to our mission of providing assistance to the people of Japan.”

Japan crisis: third explosion raises spectre of nuclear nightmare
New explosion at Fukushima plant, as engineers fought to prevent a meltdown in the second worst nuclear accident in history.

By Gordon Rayner and Martin Evans 10:06PM GMT 14 Mar 2011

The Japanese nuclear safety agency says explosion heard at Unit 2 of Fukushima Daiichi plant.

Earlier a cloud of radioactive dust billowed from the Fukushima Daiichi power plant after it suffered its second explosion in three days.

Government officials admitted that it was “highly likely” the fuel rods in three separate reactors had started to melt despite repeated efforts to cool them with sea water. Safety officials said they could not rule out a full meltdown as workers struggled to keep temperatures under control in the cores of the reactors.

The Fukushima crisis now rates as a more serious accident than the partial meltdown at Three Mile Island in the US in 1979, and is second only to the 1986 Chernobyl disaster, according to the French nuclear safety authority. After insisting for three days that the situation was under control, Japan urgently appealed to US and UN nuclear experts for technical help on preventing white-hot fuel rods melting.

The International Atomic Energy Agency (IAEA) said it was “unlikely” that the accident would turn into another Chernobyl, but failed to rule it out completely.

Meltdown alert at Japan reactor
14 March 2011 Last updated at 21:44 GMT

Technicians are battling to stabilise a third reactor at a quake-stricken Japanese nuclear plant that has been rocked by a second blast in three days.

Sea water is being pumped into reactor 2 at the Fukushima Daiichi plant after its fuel rods were fully exposed twice.

International nuclear watchdogs said there was no sign of a meltdown but one minister said a melting of rods was "highly likely" to be happening.

The crisis was sparked by Friday's 9.0-magnitude quake and tsunami.

Thousands of people are believed to have died, and millions are spending a fourth night without water, food, electricity or gas. More than 500,000 people have been left homeless.

'All our effort'

On Monday a hydrogen blast at the Fukushima Daiichi's reactor 3 injured 11 people and destroyed the building surrounding it. The explosion was felt 40km (25 miles) away and sent a huge column of smoke into the air.

It followed a blast at reactor 1 on Saturday.

Chief Cabinet Secretary Yukio Edano said there were signs that the fuel rods were melting in all three reactors.

"Although we cannot directly check it, it's highly likely happening," he told reporters.

Both explosions at the plant were preceded by cooling system breakdowns but the Tokyo Electric Power Company (Tepco) said neither blast penetrated the thick containment walls shielding the reactor cores.

It said radiation levels outside were still within legal limits.

But shortly after Monday's blast, Tepco warned it had lost the ability to cool Fukushima Daiichi's reactor 2.

Officials battled all Monday and into the early hours of Tuesday to try to keep water levels up in order to cool the nuclear fuel rods, but on two occasions the rods have been fully exposed.

Exposure for too long a period of time can damage the rods and raise the risk of a meltdown.

Four of the five pumps used to administer cooling sea water were believed to have been damaged by the blast at reactor 3.

Nuclear and Industrial Safety Agency official Ryohei Shiomi said reactors 1 and 3 had "somewhat stabilised" but "unit 2 now requires all our effort".

A Tepco official later pointed to some improvement and said the company did "not feel that a critical event is imminent".

Pressure has been released from the containment vessel, reducing the risk of a catastrophic explosion, but if the vessel is cracked it could still release radioactive material.

Elias, estás enganado!!

Vai ser um acontecimento único e que ocorre uma vez por ano.......


Vai calhar no Dia do Pai!!

Não percebi. O que é que só ocorre uma vez por ano?

[tonando]

Já ouviram falar da Super Lua Cheia que vai ocorrer daqui a alguns dias, no mínimo é bizarro !

O mundo está prestes a presenciar a aparição da maior lua cheia das duas últimas décadas. Na semana que vem este satélite natural vai chegar ao ponto mais próximo da Terra.
No dia 19 de março, a lua cheia vai aparecer mais exuberante do que o usual na noite celeste quando ela atinge o ponto máximo de um ciclo, conhecido como ‘Perigeu Lunar’.
É esperado um espetáculo visual quando a lua se aproximará da Terra a uma distância de 221,567 milhas da órbita – chegará mais próxima do nosso planeta desde 1992.
A lua cheia poderá aparecer no céu 14% maior e 30% mais luminosa, especialmente quando nascer no horizonte do oriente ao pôr-do-sol ou em condições atmosféricas bem favoráveis.
Este fenômeno é reportado como o mais relevante assunto sobre ‘supermoons’ que esta conectado com o as extremas manifestações do clima - como os terremotos, vulcões e tsunamis. A última vez que a lua passou tão próxima da Terra foi no dia 10 de janeiro de 2005, nos dias próximos dos terremotos na Indonésia que registrou 9.0 na escala Richter.
O furacão Katrina em 2005 também foi associado com a lua cheia incomum.
Previsões de ‘supermoons’ aconteceram em 1955, 1974 e 1992 – cada um destes anos tivemos a experiência de fortes manifestações climáticas.

Eu também não disse que concordava!

Como se falava numa super lua nova, deixei um artigo sobre o tema.

A minha opinião sobre a lua é um fenómeno natural já anteriormente repetido.

Sobre a ligação entre este fenómeno e os outros acontecimentos já pode estar em causa imaginações mais iluminadas!

Não tenho conhecimentos de possam dizer que existe ligação entre estes fenómenos naturais, mas uma coisa tenho como certo é que o planeta está em constante mutação!

Ok?

com o comentário This is accurate, though the numbers of people with radiation sickness are gradually increasing, nearing 100. He is reporting from a large city, Sendai, in the north with population about 1,000,000 affected by the earthquake (but not the tsunami). Also, he mistakenly reports that the tsunami warnings are finished, but actually they are still continuing - so that rescue workers have to continually evacuate.

Mais tarde, tal como escreveu o Marco:

"In Fukushima, Japan. Another nuclear reactor`s water cooling tank just exploded" e depois: "There are five tank/reactor sets at the southern Fukushima Nuclear Plant , of which #1 tank and #3 tank`s cooling systems have exploded, despite efforts to use sea water... There is another Northern Fukushima Nuclear Electric Facility about 20 kilometers to the north that has not had any explosions yet.""

Acrescentou que houve mais um alerta de tsunami igualmente:

Copio a conversa, que é mais simples:

"...the ocean level at one city went 5 meters down suddenly, but no known earthquake?!?! except a 6.0 earlier this morning... Japan Self Defense reports a three meter tsunami wave in the ocean."
