Tokyo (CNN) --Arbeitnehmer scored an important victory Wednesday in their struggle for the upper hand in the weeks long crisis win nuclear power at the site Fukishima Daiichi, although warned a top Japanese official that the fight near was about.
At dawn, authorities with the Tokyo electric power company noticed that water no longer operated one of the six building of reactor No. 2, in the Pacific Ocean from the turbine of the utility in the work.Gush was.
The tested 7.5 million times of the permitted radiation levels in the water on Saturday. On Tuesday, it was still 5 million copies of the standard.
A first attempt to fill concrete casting the 20 centimeters (8 inches) crack, through which this water was gushing, failed. And there was no immediate evidence to suggest that the injection Sunday titled a silica-based polymer "liquid glass" entweder-- until worked Wednesday morning.
The apparent success in plugging up the broken concrete means wave, that, as Wednesday afternoon, there was no known large radioactive emissions into air, water or soil.
Still, reporters Japanese Chief Cabinet Secretary Yukio Edano soon, that the Krise--which was marked by spills, explosions and apologies since the earthquake and tsunami from the systems used on 11 March, the cool fuel klopfte-system - not over.
"Is it completely stopped?" "There are no other areas where is released (radioactive) water?" Edano said. "We can not optimistic, be only because we could close this one."
We can not optimistic be, just because we plug this one could-Japanese Chief Cabinet Secretary Yukio Edano
Hidehiko Nishiyama, an official with Japan's nuclear and industrial Agency, said Wednesday that authorities is aware that other problems could, especially as excess water still the No. 2 unit turbine can be building basement flooding.
"(We) are aware that water can build more leakage elsewhere lead," he said.
Meanwhile, the same official said that almost all of the approximately 10,000 tons of radioactive water from the plant waste water treatment facility in the Pacific Ocean as the clock Wednesday dumped was had.
This happened in the waste water to room building for the much more radioactive water, from in and around the No.2 unit be pumped.
Edano said that it was a trade-off, with authorities argument that as a whole was dumping water, 1 / 200, 000ths the amount of radiation, "inevitable" and a way to minimize damage to the environment.
Edano conceded that not enough good work authorities declared the plan-announced and begun Monday-a total of 11,500 tons (including some from in and around the No. 5 and 6 units) has to take in the Pacific Ocean.
Officials in nearby countries, as well as in Japan, "point out that we have not fully reported," he said on Wednesday.
"We (more information) have reported to the people, which can be affected, in particular on the neighbouring countries," Edano, said amid reports by South Korean media, officials in Seoul among were upset.
"It was a measure to prevent more serious marine contamination, but we want to explain, the better argument."
Locals were among the fishermen angered by the deliberate release of toxic substances into the sea, potentially add to a level of radiation measured several hundred - thousand times the permitted monitoring sends a few dozen meters from the nuclear facilities.
Members of the Association of fisheries of voiced their anger in a Wednesday morning meeting with Tokyo Electric officials. The fishing industry trade group officials often felt she completely ignored, after it the utility not to radioactive water in the sea-dump asked just to, hours later learn, started the process.
In addition, the Association is called Tokyo Electric Company's previous claims that nuclear power safe, and that such accidents would never happen.
The fishermen fear has intensified with the discovery, announced on Tuesday, abnormally high levels of radioactive iodine "in a sample of fresh fish." This led the Japanese authorities to regulate the radiation on seafood for the first time.
Edano acknowledged on Wednesday that could keep the fishing industry and the need for problems which affect large developments, the safety and quality of seafood.
The Japanese Government is considering "provisional compensation" give a direct boost to Fischer, before a more definitive payment plan, that can be set in the future.
Some farmers are likely to receive payments even after the introduction of the limitations of certain products and milk due to radiation safety concerns linked to the nuclear crisis.
The concerns, experts said the release of radiation in seawater-in the light of the current plan, and in particular, if there are no further will not leak of the most poisonous fabrics-likely long-term health risks to humans are still marine life. It also helps that most of the radiation detected iodine-131, is half of its radiation loses every eight days.
The dump being 11,500 tons of radioactive water about five swimming pools full, compared to "about 300 trillion swimming pools of water", which fill the Pacific Ocean, said Timothy Jorgensen safety Chairman of the Committee, radiation at the Georgetown University Medical Center.
"So hopefully that quickly churning of the ocean and the streams that will dissipate so that it gets too much you dilute concentrations relatively quickly."
After a turbulent first weeks, utility and Government officials have described conditions in the plant reactors and spent fuel pools as generally stable. Airborne radiation in the vicinity and long way off, have meanwhile steadily declined.
The existence of significant amounts of collected radioactive water around the plant, nor can it other Lecks-and other problems. And it is still a big problem is that cool to keep more workers to the nuclear fuel inject large amounts of water.
"Conservation of the cooling water is almost impossible, and creates the only exposure to radiation and contaminating more water, soil and the atmosphere," said Tesunari IIDA, a former nuclear engineer, Tuesday.
The Japanese power industry analyst said, that it is important, authorities, as soon as possible, search plug in you far beyond the latest leak, or transmit any contaminated water from one place to another. Does determine that one feasible, effective way to ensure that the nuclear fuel still on the site of Fukushima Daiichi never again is a threat.
"This type of ad-hoc solutions is soon dead end." We need more complete solutions, "a critic of the nuclear power industry said IIDA, now." "We have to think about an exit strategy-with a grave with zinc or Tin, or manure mixed with sand or any other kind of means to cool down and contain the reactors."CNN's Whitney Hurst, Matt Smith and Kyung LAH and journalist Hiroo SASO contributed to this report.
