Except for the ear piercing, which I detest, that girl looks really pretty.
Anyways, not denying the 3-11 tsunami that caused all of this, but a lot of the Fukushima news is overhyped. One only needs to look at the uranium spot price chart to see why. Prior to 3-11 tsunami in Japan, uranium prices (and stocks) boomed like it was in a tulip bulb mania market. It profited everyone who shorted uranium at the market top to make news of Fukushima even years after the 3-11 incidence to drive down uranium prices....
Look at this crazy U308 chart. The insiders needed Fukushima/ 3-11 2011 to drive the sucker down hard afterwards!

interesting. The same thing with put options weeks prior to 9-11. It was trading 3x the normal average day volume.

from Japan Times. I don't think the Abe government is doing enough wrt nuclear reactor safety.
This may come back and bite them again and again.

Former nuclear regulatory body official calls for review of safety screening method
JUN 12, 2016
Japan needs to review its current method for screening nuclear plant safety, seismologist and former senior regulator Kunihiko Shimazaki said in a recent interview.
The current method risks underestimating the magnitude of possible earthquakes that may hit nuclear plants, Shimazaki, former acting chairman of the Nuclear Regulation Authority, said.
“A review is needed” for the method to calculate the design basis quakes that is currently adopted in the NRA’s screening procedures, he said.
Shimazaki said that he has confirmed the need for such a review after examining data on powerful quakes that hit Kumamoto Prefecture and other areas in Kyushu in April.
“The NRA has to be aware that the current screening procedures have shortcomings,” he said, adding it is “very dangerous to keep using the method.”
Before leaving the NRA in September 2014, Shimazaki was in charge of assessing quake and tsunami impacts in its nuclear safety screening.
The current method risks underestimating design basis quakes when it is applied to vertical faults found mainly in western Japan, according to him.
The design basis quakes for Kansai Electric Power Co.’s Takahama and Oi nuclear plants, both in Fukui Prefecture, and Kyushu Electric Power Co.’s Genkai nuclear plant in Saga Prefecture, should be recalculated based on a different method, he said.
The NRA should draw up a revised method by taking into account new data, including on strong tremors such as the Kumamoto quakes, Shimazaki said.
The Nos. 3 and 4 reactors at the Takahama plant have passed the NRA’s safety screening. The NRA is expected to approve Kansai Electric’s request for extending operational periods at the plant’s Nos. 1 and 2 reactors beyond 40 years, a basic lifetime for nuclear reactors in Japan.

Safety performances of CAP1400, the newest China-developed nuclear power station.
In case a Fukushima-alike earthquake/tsunami occurred to CAP1400, the passive safety system, with no human intervention, is able to keep the CAP1400 safe for 72hours. The traditional reactor could only assure a 30min safety time (with no human intervention). Within the 72hours, government could allocate sufficient technology/human resources to tackle with the nuclear accident.

I agree. However, looking at the Japanese Islands, there isn't much coastal land that allows for the 100 km buffer. Their islands are quite hilly.
Although Japan is caught between a rock and a hard place, they should NOT sacrifice safety.
.
Keep in mind that in emergencies, 72 hours is not a long time.
IMHO, the goal is to make nuclear reactors as safe as they can be, so that in whatever situations, we don't have an emergency. If that's not possible, let's make the nuclear reactors as safe as possible.

I don't think the Abe government has given all the details .... yet.

China Hopes Japan to Give True Picture of Fukushima Nuclear Leak

China has again urged the Japanese government to give an honest explanation of the Fukushima nuclear leak incident and its impact on the environment as soon as possible.
Foreign Ministry spokesman Lu Kang made the remarks after the Japanese government decided to lift the evacuation order in the highly radiated "residential restricted area," allowing evacuees to return to where they used to live.
"We have noticed that since the responsible person of the atomic energy department of the Tokyo Electric Power Company disclosed on May 30 the truth that had been concealed for five years, the Japanese government has, up to the present, not made any responsible and open response to the matter."
He added that the impact of the Fukushima nuclear leak on the environment, ecology and food safety is not limited to Japan itself.
Lu also addressed the issue of whether Chinese tourists to Japan are safe.
"I want to clarify that it is the freedom and choice of each and every Chinese citizen to make their own travel plan. But the Chinese government has responsibilities to give a necessary warning when there are uncertain risks and it is the compelling obligation of the Japanese government to give an honest and true answer of the Fukushima nuclear leak and its impact as soon as possible."
The Chinese Foreign Ministry has issued an alert, warning Chinese citizens and tourist groups to be cautious when going to Fukushima, and other seriously affected areas.

Japan is always hiding, from atrocities to disasters.
Hiding, denying, beautifying...

World Nuclear Association says most nuclear fuel melted at Fukushima nuclear plant
Source: Xinhua 2016-06-27 15:54:52
LONDON, June 27 (Xinhua) -- Recent tests carried out by the Tokyo Electric Power Co.(TEPCO) found little or no nuclear fuel in its original location inside some reactors at the Fukushima plant, a nuclear expert told Xinhua in an interview.
Jonathan Cobb, senior communication manager of the London-based World Nuclear Association, said this after the Japanese company was again suspected to have delayed the disclosure of a meltdown five years ago.
A report published earlier this month said TEPCO's former head Masataka Shimizu instructed staff not to use the term "core meltdown" in describing the situation at the Fukushima Daiichi nuclear complex when the nuclear disaster first struck in March 2011 following a powerful earthquake.
"There is no precise definition of a meltdown, but it represents a significant level of core damage where most of the reactor core has melted," said Jonathan Cobb, senior communication manager of the London-based World Nuclear Association.
According to media reports, TEPCO had defined a meltdown as damage to more than 5 percent of the fuel in its internal manual, but the company eliminated the definition from the manual in revisions after the Fukushima disaster.
Inside-the-reactor images that TEPCO managed to get recently showed that there is "little or no fuel to be present where it normally operates in the reactor" so the utility giant concluded that most of the nuclear fuel has melted and fallen to the bottom of the reactor pressure vessel, Cobb said.
"It is true that TEPCO initially underestimated the amount of damage there had been to the fuel cores of the three affected reactors. That there has been more extensive melting will mean it will be more challenging to eventually extract the fuel from the reactors," he added.
On TEPCO's ongoing project of "ice wall" -- an underground wall of frozen soil designed to prevent contaminated groundwater from leaking into the environment, Cobb said it should further help reduce the inflow of groundwater into the site, but he also warned that such projects should be introduced cautiously to ensure that they are working as expected.
While noting that TEPCO and the Japanese government have been providing "a huge amount of information and data" ever since the accident occurred, Cobb said they often failed to give enough context and explanation to help people understand such information.

Thanks god, hope the sea between China and Japan could reduce the potential impacts to China from the nuclear fuels meltdown.

That's why we should boycott their next Olympic Games, since their irresponsible behavior has caused this disastrous mess to the ecosystems of this planet. And their soil is now full of radiation which is extremely unsafe for the athletes.

They could prevent the meltdown of the nuclear plant, but they didn't seal it.
They still acted cheaply and wanted to preserve the damaged reactor.

Japan used to have a good reputation, products made in Japan are synonymous with quality.
Unfortunately, it is no longer the case. This Fukushima disaster has done undue damage to Japan's reputation.
Moreover, with its economy limping along, it doesn't help either.
The irony - if TEPCO had spent a little bit more money on prevention, this disaster would not have occurred.
Remember the saying, "Penny wise, pound foolish."
