The operator of Japan's crippled nuclear plant laid out a blueprint Sunday for stopping radiation leaks and stabilizing damaged reactors within the next six to nine months as a first step toward allowing some of the tens of thousands of evacuees to return to the area.

While the government said the timeframe was realistic, those forced to flee their homes, jobs and farms were frustrated that their exile is not going to end soon. And officials acknowledge that unforeseen complications, or even another natural disaster, could set that timetable back even further.

"Well, this year is lost," said Kenji Matsueda, 49, who is living in an evacuation center in Fukushima after being forced from his home 12 miles (20 kilometers) from the plant. "I have no idea what I will do. Nine months is a long time. And it could be longer. I don't think they really know.

Radiation Leaks Into Groundwater Under Japan Nuclear Plant

Japan -- Radiation exceeding government safety limits has seeped into groundwater under a tsunami-crippled Japanese nuclear plant, according to the operator, but experts said Friday that it was unlikely to contaminate drinking supplies.

The leak is, however, a concern and an indicator of how far the Tokyo Electric Power Co. is from stabilizing dangerously overheating reactors after cooling systems were knocked out in the March 11 tsunami.

TEPCO has increasingly asked for international help in its uphill battle, most recently ordering giant pumps from the U.S. that were to arrive later this month to spray water on the reactors.

The groundwater contamination was found in concentrations 10,000 times higher than the government standard for the plant. The iodine-131, a radioactive substance that decays quickly, was nearly 50 feet (15 meters) below one of the reactors, according to TEPCO spokesman Naoyuki Matsumo.

Seiki Kawagoe, an environmental science professor at Tohoku University, said the radioactive substances were unlikely to affect drinking water, noting that radiation tends to dissipate quickly in the ground, as it does in the ocean.

But there are two ways the iodine could eventually affect drinking water if concentrations were high enough. One is if it were to seep into wells in the area. For now, a 12-mile (20-kilometer) radius around the plant has been cleared, though residents of the area are growing increasingly frustrated with evacuation orders and have been sneaking back to check on their homes.

The other concern is that contaminated water from the plant could seep into underground waterways and eventually into rivers used for drinking water. Tomohiro Mogamiya, an official with the Ministry of Health, Labor and Welfare's water supply division, said that was "extremely unlikely" since groundwater would flow toward the ocean, and the plant is right on the coast.

There are two nearby filtration plants for drinking water, and both have been shut down because they are just inside the exclusion zone. One takes water from the Kido River, to the south, and another takes it from groundwater below Odaka, to the north. Both are several miles (kilometers) from the coast, and therefore on higher ground.

Japan On 'Path Of Core Melt' Nuclear Accident

Japan is “on the path of a core-melt accident,” a nuclear expert tells Newsmax in an exclusive interview.

The news Friday afternoon that the only nation that ever has endured a nuclear-weapons attack is venting contaminated vapor from a nuclear power plant’s containment core could indicate that the coolant loss is quite serious, says Mark Hibbs, a Berlin-based senior associate at the Carnegie Endowment for International Peace, a nonprofit think tank. Hibbs, who works in Carnegie's Nuclear Policy Program, has spent 20 years reporting for nuclear-energy journals and has spoken with Japanese officials in the aftermath of the nuclear plant mishap resulting from the earthquake there.

Japanese officials have evacuated 3,000 residents who live near the damaged reactors as a precautionary measure, according to Fox News. The pressure inside the reactor containment domes is 50 percent higher than normal, the officials say, although they contend that a last-ditch emergency cooling system is intact.

“The Japanese public is generally very alarmed about things like radioactive emissions,” says Hibbs, who served for two decades as an editor and correspondent for the nuclear energy publications “Nucleonics Week” and “Nuclear Fuel.” “They have an extreme high standard of safety protection, and they don’t like to see risks like this taken even if the risk is small.

“It’s a very, very risk-averse culture in this regard. So if the authorities are willing to do this, that might be a sign of how serious they perceive the threat to the reactor.”

Although coolant interruptions to nuclear power plants are not all that unusual, says Hibbs, who adds that the surprising aspect of this incident is that Japan’s redundant systems apparently have been unable to counteract reactor core heating.

“What happened in Japan is very alarming because it would appear . . . that about 2:30 this afternoon Japan time, when the earthquake struck . . . three of the reactors that were operating were disenabled because of a loss of offsite power that was caused by the earthquake.”

The Japanese situation appears to be roughly analogous to the Three Mile Island incident in the United States, where authorities struggled for days to contain an improperly cooled reactor core but were able to avert a widespread release of nuclear material.

“We were in a situation as I recall then very similar to where we are now, where we were told by news media in 1979 that there was a core melt accident unfolding, we didn’t know how serious it would become, and what would happen,” Hibbs tells Newsmax.

At least one of the reactors in Japan, and perhaps more, “ are on the path of a core-melt accident. It’s called a loss of coolant accident. . . . And it’s up to the Japanese authorities, together with the industries in that country, to find a way to stem this problem,” he said.

Secretary of State Hillary Clinton confirmed that the United States is trying to help alleviate the situation. "We just had our Air Force assets in Japan transport some really important coolant to one of the nuclear plants," Clinton said, according to the Associated Press.

The Japanese reactors are designed to drop neutron-blocking control rods into the core as soon as the plants detect a seismic disturbance. These controls apparently functioned normally. But even after the procedure, scientists say a base level of heat continues to flow, and coolant is needed to constrain those temperatures.

Asked how long Japanese scientists have to correct the problem to avoid a core meltdown, Hibbs tells Newsmax that it depends on system design, adding, “it could be a day, plus or minus 10 hours.”

“After a while, with the heat building up in there, and lack of coolant, you’re going to see damage in your fuel, the cladding, the metal container around the nuclear material, begins to buckle or balloon or break, and after a little while you’ll get a situation where the fuel falls apart, melts, and falls into the core, and then you’ve got a classical core melt accident like you had in Three Mile Island that you had in the United States in '79.”

Hibbs spoke with Japanese government officials who told him the force of the tsunami was so severe that the water may have flooded the reactors,  power generators, and cooling mechanisms, disabling the equipment. "Which means they have to resort to basically a military-type exercise, to rush in to the devastated site equipment that they can quickly hook up to the reactor to get power in there and start this emergency equipment, to get cooling water into that core and prevent that fuel from overheating.

“And if they can’t do that,” he told Newsmax, “then you’re going to have this meltdown.”

They have 24 hours or so to avoid a core meltdown, he says. But if one occurs, two scenarios could follow: The good outcome would mirror what happened at Three Mile Island, while the bad one could involve what he called a “Chernobyl scenario, where the damage to the reactor was such that the integrity of the structures were damaged.

Will the Gulf Oil Spill Be This Generation’s Three Mile Island?

As we once wrote, you can make the argument that the 1979 accident at the Three Mile Island nuclear-power plant — which came just 12 days after the release of the film The China Syndrome, a cautionary tale about a nuclear-plant meltdown — helped stop the U.S. nuclear-energy industry dead in its tracks. While other countries soldiered on — France, Japan, Switzerland and Sweden, to name just a few — the U.S. turned away from nuclear, in large part because of public and political fear generated by what turned out to be a relatively harmless accident. There were other barriers to nuclear, of course, including cost overruns and regulatory nightmares; but once the sentiment turned, those more substantial barriers became secondary.

Does anyone have the sense that the recent BP oil disaster in the Gulf of Mexico may come to be seen as a Three Mile Island moment, at least for the prospects of U.S. offshore drilling? President Obama has called the spill a “potentially unprecedented environmental disaster” — just weeks after he endorsed an increase in offshore drilling, to the deep chagrin of a broad swath of his supporters and environmentalists.

To be sure, there are key differences between the BP spill and TMI, the chief one being that our economy today is (still) very much dependent on oil, whereas our economy in 1979 was not very much dependent on nuclear power. Nor is it today, even though the U.S. does make more electricity from nuclear power than another other country in the world — although, when ranked by share of overall electricity, the U.S., with 20 percent coming from nuclear, is roughly in the middle.

That said, could the Gulf disaster be just the kind of tragic, visible, easy-to-comprehend event that crystallizes the already-growing rush to de-petroleum our economy? As with TMI, it won’t do much to change the facts on the ground about how energy is made. But as we’ve seen before, public sentiment can generate an awful lot of energy on its own, for better or worse.
