Setback at nuclear plant?

Tokyo (CNN) -- Radiation levels in pooled water tested in the No. 2 nuclear reactor's turbine building at the Fukushima Daiichi power plant are 10 million times above normal, utility company and government officials said Sunday.
Hidehiko Nishiyama, an official with Japan's nuclear and industrial safety agency, said the surface water showed 1,000 millisieverts of radiation. By comparison, an individual in a developed country is naturally exposed to 3 millisieverts per year, though Japan's health ministry has set a 250 millisievert per year cumulative limit before workers must leave the plant.
The 10-million-times normal reading applies to radioactive iodine-134 found in the No. 2 building's pooled water, according to the nuclear safety agency. This isotope loses half its radioactive atoms every 53 minutes, compared to a half-life of every eight days for radioactive iodine-131 that has also been detected in recent days.
This exponentially dwindling amount of radiation means, according to Nishiyama, that it's unlikely that sealife -- and, several steps down the line, humans who might eat once contaminated seafood -- will suffer greatly from the iodine-134 exposure.
"Certainly, we have to be concerned about the fact that the level of radiation is increasing," said Nishiyama. "But at this point, we do not ... envisage negative health impacts."
There was no indication either of harm done to the two people working in and around the No. 2 reactor when the test result became known. Those two subsequently left, and work in the turbine building has stopped until the government signs off on the power company's plan to address the issue, according to an official with the Tokyo Electric Power Company, which runs the plant.
That said, a Tokyo Electric official noted Sunday that people continued to work in other buildings -- including a control room, which got power and light for the first time in weeks the previous afternoon -- in the No. 2 reactor's complex.
Work has similar ceased at the No. 3 reactor's turbine building, where tests earlier indicated radiation 10,000 times normal in that structure's basement.
Eventually, authorities want to pump the pooled, and contaminated, water from both these reactors' turbine buildings. This happened again Sunday in the No. 1 reactor's turbine building, where tests had showed some radioactive contamination, although nowhere as high as in the other two locales.
Authorities are still trying to pinpoint the relationship, if any, between these alarming readings from inside all these buildings to a continued spike in radiation detected in seawater just offshore.
A Japanese nuclear safety official said Sunday that levels of radiation were 1,850 times normal at a monitoring post situated 330 meters (361 yards) into the Pacific Ocean. This is near the discharge canal for the Nos. 1, 2, 3 and 4 reactors.
On Saturday, similar readings from the same monitoring posts showed readings were 1,250 times above normal. The previous day, they'd been lower -- at 104 times more than a typical level.
This substance is a biproduct during the nuclear energy process, and officials suspect the seawater contamination may be a direct result of problems at the plant.
These setbacks notwithstanding, a Tokyo Electric official said that fresh water -- and not seawater, as had been done earlier -- is still being injected into the reactor cores and the spent nuclear fuel pools for the Nos. 1, 2 and 3 units.
That is critical as it suggests that measures continue to ensure that nuclear fuel rods there are kept cool, in order to prevent overheating and the release of more airborne radiation.
Up until Sunday, the potential for contamination from the No. 3 reactor had been a primary concern. This unit, which has had a building severely damaged by a hydrogen explosion and that an official said last week might have leaked radiation from its reactor core, is the only one of the facility's six reactors to use a combination of uranium and plutonium fuel, called MOX. Experts say this mix is considered more dangerous than the pure uranium fuel used in other reactors.
Three men laying cable in the No. 3 unit turbine building's basement have been hospitalized after stepping in the highly radioactive water there on Thursday.
On Sunday, Japanese Chief Cabinet Secretary Yukio Edano confirmed that these workers would likely be released Monday from the hospital, which he characterized as a "good development."
An official with Tokyo Electric Power Company, which runs the plant, apologized Saturday, saying the exposure might have been avoided with better communication.
Hideyuki Koyama, the company's associate director, said pooled water had been discovered in the basement of the No. 1 reactor six days earlier. But a sample was not taken for analysis until the 24th, after the three workers were exposed to between 173 to 181 millisieverts of radiation.
Edano told reporters Saturday the company has been given "stronger instructions" to fully and quickly disclose information about the plant's conditions, so the government can ensure "proper safety measures."
As important, the chief secretary said, was the need for Tokyo Electric to be upfront with the Japanese -- millions of whom get power from the company and millions more of whom have been affected by radioactive emissions from the crisis.
"We need to be sure that (Tokyo Electric) isn't going to act in a way that will create distrust," Edano said.
Koyama told reporters that radiation alarms went off while the three men were working, but they continued with their mission for 40 to 50 minutes after assuming it was a false alarm.
This continued debate about the working conditions for the roughly 500 individuals -- among them utility workers, Japanese soldiers and firefighters from several cities -- comes as work continued Sunday to cool nuclear fuel at the plant and prevent the further emission of radioactive material into the air and sea.
The Nos. 1, 2 and 3 units have been authorities' chief focus, since they were the only ones operating (and, thus, the only ones with nuclear fuel rods in the reactor cores) when the March 11 earthquake and subsequent tsunami hit.
Authorities have been trying to restart a steady supply of electricity to power the cooling systems, in order to control the temperatures of nuclear fuel and prevent further radioactive emissions, for that reactor and several other in the nuclear facility.
This has already occurred in the Nos. 5 and 6 units, which are considered stable. These units have fuel rods in spent fuel pools, but not in their reactor cores.

Tokyo (CNN) -- Radiation readings that showed extremely high levels of a form of radioactive iodine at the earthquake-damaged Fukushima Daiichi nuclear power plant were incorrect, the plant's owner said Sunday.
The Tokyo Electric Power Company reported earlier that water pooling in the turbine building of the plant's No. 2 reactor was 10 million times more radioactive than normal and contained a sharply elevated level of iodine-134, a short-lived isotope produced in a nuclear reaction. But the utility acknowledged that those figures were incorrect late Sunday, after Japanese regulators questioned the readings.
"Presently, we are re-sampling, analyzing and re-evaluating, and as soon as it's collated, we will make an announcement," the company said.
Tokyo Electric reported earlier that radiation levels in that water had hit 1,000 millisieverts per hour -- more than 330 times the dose an average person in a developed country receives per year, and four times the top dose Japan's health ministry has set for emergency workers struggling to prevent a meltdown at the damaged plant.
High radiation levels persisted in the Pacific Ocean waters near the seaside power plant, however, with one monitoring post reporting levels 1,850 times normal Sunday. And tests at the No. 3 reactor building suggested sharply elevated radiation levels as well, the utility said.
Experts suspect that three of the six reactors at Fukushima Daiichi, located about 240 km (190 miles) north of Tokyo, suffered damage to their radioactive cores after the March 11 earthquake. The magnitude 9 quake and the tsunami that followed knocked out backup generators that ran their coolant systems and damaged water pumps at the plant, forcing workers to scramble to prevent a meltdown.
Hydrogen explosions severely damaged the buildings housing the No. 1 and No. 3 reactors in the days following the quake, while an explosion also may have occurred inside No. 2 -- the source of the extremely high readings Sunday.
"The radioactive material that is found in that water is either from the reactor itself or the spent fuel pool," said Hidehiko Nishiyama, a NISA spokesman. "At the moment, we consider that the possibilities are higher that the water is from reactor."
He said the pressure vessel surrounding the core of the No. 2 reactor was not believed to have been damaged -- but the water could be leaking from valves or pipes connecting the reactor to other parts of the plant.
Nishiyama told reporters it was "not possible" that radioactive water was leaking into the ocean from the plant. He suggested runoff from the area around the damaged plant may have carried radioactive particles into the ocean, but said no definite source had been identified.
Sunday's erroneous test results stopped work at the No. 2 reactor, and there was no indication of harm done to the two people working in and around the turbine house. Tokyo Electric said crews continued working in other buildings in the No. 2 reactor's complex, including a control room, which got power and light for the first time in weeks Saturday afternoon.
Iodine-134 has a radioactive half-life of 53 minutes, compared to eight days for another reactor byproduct, iodine-131, that is far more common. Nishiyama said earlier that NISA considered the extremely high radiation figures "a bit odd," based on a high ratio of iodine-134 to a more common reactor byproduct, iodine-131.
Eventually, authorities want to pump the pooled, contaminated water the reactors' turbine buildings. This happened again Sunday in the No. 1 reactor's turbine building, where tests had showed some radioactive contamination, although nowhere as high as in the other two locales.
But high radiation levels also stopped work at the No. 3 reactor's turbine building, where tests earlier indicated radiation 10,000 times normal in that structure's basement. And 19 plant workers have received doses of radiation of more than 100 millisieverts, both the utility and the Nuclear and Industrial Safety Agency reported Sunday.
Tokyo Electric said fresh water -- and not seawater, as had been done earlier -- was still being injected into the reactor cores and the spent nuclear fuel pools for the Nos. 1, 2 and 3 units.
Up until Sunday, the potential for contamination from the No. 3 reactor had been a primary concern. This unit, which has had a building severely damaged by a hydrogen explosion and that an official said last week might have leaked radiation from its reactor core, is the only one of the facility's six reactors to use a combination of uranium and plutonium fuel, called MOX.

The Nos. 1, 2 and 3 units have been authorities' chief focus, since they were the only ones operating when the March 11 earthquake hit. Units 5 and 6 are considered shut down and stable, while Unit 4's fuel rods had been removed before the quake.
Authorities have expressed concern about the spent fuel from Unit 4, which was placed in a cooling pool adjacent to the reactor. That pool has been the target of repeated efforts to spray water into the reactor housing, which was damaged by a fire March 15.
