Tokyo Fire Department to start spraying water
The Tokyo Fire Department plans to use a temporarily unmanned fire engine to spray water into the No. 3 reactor's storage pool at the quake-hit Fukushima Daiichi nuclear power plant.
The operation is expected to last for 7 hours.
The fire engine has a foldable arm that can spray water from a height of 22 meters.
A vehicle equipped with a large pump is parked at a dock 300 meters from the fire engine to suck water from the ocean.
The sea water will be supplied to the fire engine by hose.
Firefighters laid the hose on the ground by hand on Friday night.
Firefighters will calculate distance and direction, and then leave the fire engine before starting to spray water into the storage pool.
The unmanned operation permits water to be sprayed for a long period of time without exposing firefighters to radiation.
The Tokyo Fire Department plans to spray water for 7 hours on Saturday, while refueling the vehicles.

yeah, 7 hours, in which they plan to spray 1200 tons of water onto reactor3s storage pool, which should almost fill it
radiation is still around 350 micro sieverts at the plant, its not really going down so far :/

I feel that the whole nuclear scare is just a side show to the very real damage brought by the earthquake and tsunami.
Hear hear...
and once more, had the japanese government disclosed more information and kept everybody up to date about everything that was going on, had constantly provided updates about the radiation levels and situation at the plants, international media would have cited it and taken it seriously instead of speculating. and people would trust its assessments and not over-react...Quote:

btw, so are us and russian experts at the site now?
did the us set up their own measuring equipment?
if not, i have a feeling we may never know what REALLY happened... things might have been much worse at one or another point in time than the gov claimed, but now that they seem to have everything under control, its easy to cover up any details about mistakes they might have made...
this is all highly political and all people involved want to move on asap and probably pretend it never happened or everything was fine all along and the media just blew it out of proportion...
we still dont fully KNOW today, at least the public doesnt, what exactly happened at chernobyl... i hope for fukushima things will be different... but its probably not in the interest of any of the high powers involved here so im sceptical that there will ever be an accurate report of the events.
You think chernobly lacks enlightenment... how about the Kyshtym disaster... 30 years noone even knew it happend...
never heard of it :DQuote:

i honestly believe that if the gov and atomic industry would disclose all infos properly, and stop trying to keep ancient reactors up and running, most people would support atomic energy as a necessary evil, because the alternatives are burning more fossil fuels, more dependency on autocratic fascist human rights violating regimes in the middle east, more pollution and higher energy costs...
but the way things are run right now...
i honestly feel a strong urge to GTHO from nuclear energy as well, no matter the cost...
its like a cheating girlfriend, in the end your better off without her :D
same with the atomic industry :D
saaya... you are conscious that petroleum prices are going sky high if Nuclear energy is left aside ... not to talk about that all the ambient agreements about co2 emissions will be blown away ...
So... it's not that easy... i defend nuclear power BUT... big BUT with gen3 plants andddd with a great effort to bring out gen4 ...
TEPCO have succeeded in connecting a new external power cable to units 1 and 2. They will undergo inspection today (20th) to check the pump and valves in order to ensure they function.
I heard they drilled holes in reactors 5 and 6 this morning to vent steam. I guess the generators weren't keeping up with the cooling needs.

If you guys got more live feeds of radiation data, why not post it?
With enough of them you could estimate more accurately...
I have not checked out the german news yet.
The usa news I haven't seen much of it, just cnn so far.
As for power plant stuffs..
I think since we can grow fuels we should be doing that.
Figuring out which has the least environmental impact and which has the best octane and balancing it, wood pellets/gases, coal/gases or algae gases.
Oil and gas are fine as long as there isn't mass spills, or even sinking ships... and people deliberately putting mass amount of gas and oil into the ocean and lighting it on fire lol... :shakes:
Methane gas.
Solar turbine dish's.
Hybrid car's should of been out years ago in much bigger #'s.
And I personally think they should be using a small gas powered generator to the side of the engine to power the engine or to charge the batteries...
Finding a few gal's of gas isn't so hard, charging your batteries for a few hr's at an outlet would suck on the road.
I honestly think we should be doing mass hydroponics too...
But whatever lol :P.
Latest Update
Tokyo Electric Power Company says radiation levels around the compound at its Fukushima Daiichi nuclear plant are on the decline since water-spraying began in earnest on Saturday afternoon.
The company told reporters that the radiation level at the plant's headquarters building, located some 500 meters northeast of the No. 3 reactor, dropped to 2,625 microsieverts per hour at 8:30 on Sunday morning.
The reading shows a drop of more than 800 microsieverts from 18 hours ago--about the time the water-spraying at the No.3 reactor began.

Sounds to me like the radiation is still going up.
FUKUSHIMA, Japan – Technicians prepared to vent radioactive gas into the air Sunday because of a new spike in pressure at Japan's crippled, leaking nuclear complex............
...............The venting is an "unavoidable measure to protect the containment vessel," Nishiyama said. He warned that a larger amount of radiation would have to be released than when similar venting was done a week ago because more nuclear fuel have have degraded since then.

They should get a bunch of fabric/cloth/whatever and cover the exposed reactor where they vent the coolant a bit, it would help to keep the escaping steam from carrying radiation away.
Its known as a "Volenti Cooler" btw, basically acts just like a "bong" cooler.

Pressure rises again in No. 3 reactor:(
Technicians prepared to vent radioactive gas into the air Sunday because of a new spike in pressure at Japan’s crippled, leaking nuclear complex, while a safety official said protective iodine pills should have been distributed near the plant days earlier.
Radiation, a danger for days in areas around the plant, already has seeped into the food supply, with the government warning that tests of spinach and milk from areas as far as 120 kilometers away exceeded safety limits. Tap water farther away turned up tiny amounts of radioactive iodine in Tokyo and other areas.
Amid concerns of wider contamination, a nuclear safety official said the government was caught off-guard by the accident’s severity and only belatedly realized the need to give potassium iodide to those living within 20 kilometers of the Fukushima Dai-ichi nuclear complex.
Quote:
Radioactivity tests have found that milk from Fukushima and spinach from Ibaraki contain levels of iodine-131 that exceed safety standards:
In raw milk samples collected from a farm in the town of Kawamata in Fukushima prefecture, up to 1,510 becquerel per kilogram of iodine-131 were detected, about five times the limit of 300 becquerel per kilogram set by law.
“This will be a huge blow to dairy farms all over Fukushima,” said Yukimitsu Sato, a spokesman for the prefecture’s dairy farm cooperative, which represents about 60% of local dairy farms, including the one in Kawamata.
The prefecture had not shipped milk for consumption since the earthquake, and the health ministry’s announcement came just as the cooperative was preparing to begin shipping again.
“We were just starting to see a ray of hope,” said Mr. Sato, adding that the cooperative was not told about the radioactivity tests.
According to the cooperative, Fukushima prefecture’s 516 dairy farms usually ship 254 tons of milk every day, with annual sales of about ¥10 billion (about $125 million). About 1.3% of dairy cows in Japan were in Fukushima as of 2008, according to the prefecture.
The health ministry also detected higher-than-normal levels of iodine-131 from spinach samples collected Saturday from farms in six locations in Ibaraki prefecture, south of Fukushima.
One spinach sample collected from the city of Hitachinaka, located about 120 kilometers south of the plant, contained 8,420 becquerel per kilogram of iodine-131, according to the health ministry. The normal amount set by Japanese law is 2,000 becquerel per kilogram.
Another spinach sample from Takahagi, a city closer to Fukushima, recorded 15,020 becquerel per kilogram, more than seven times the normal amount. From that sample, radioactive caesium 134 and caesium 137 were also detected in slightly larger amounts than the limits set by law.
The Ibaraki prefectural government has asked farmers to suspend shipments of spinach, according to the Ibaraki branch of the National Federation of Agricultural Cooperative Associations.
An official in Ibaraki prefecture said that he couldn’t deny the possibility that some spinach from the prefecture has already reached consumers. The prefecture produces about 14,000 tons of spinach a year, about 5% of overall production in Japan.
Tokyo Electric Power Co. said at a press conference Saturday that it was prepared to offer compensation to farmers.
It is also being reported that tap water in the Kanto region has been found to contain trace amounts of iodine-131, but the levels do not exceed safety standards:
Radiation was detected in water in Tokyo and the prefectures of Tochigi, Gunma, Saitama, Chiba and Niigata, Japan’s Ministry of Education, Culture, Sports, Science and Technology said today in a faxed statement.
Tochigi Prefecture’s reading of radioactive iodine-131 was 77 Becquerel per kilogram, the highest among the prefectures, while the level of iodine found in Tokyo’s Shinjuku district was 1.5. All the numbers were within the 300 Bq/kg limit, the ministry said.
This is not an unexpected development, nor is it a sign of a new radiation leak. The explosions at the Fukushima plant earlier in the week caused higher-than-normal radiation readings throughout Tokyo (which have since dropped considerably). At such levels, direct exposure would not harm human health, but it could build up to unhealthy levels in crops and livestock that feeds on local vegetation.
To summarize:
Iodine-131 in Vegetables
* Japanese legal limit on radiation in spinach (and other vegetables): 2,000 per kilogram
* Amount of radiation detected in spinach from Takahagi, Ibaraki prefecture: 15,020 becquerel per kilogram (plus caesium 134 and caesium 137)
* Amount of radiation detected in spinach from Hitachinaka, Ibaraki prefecture: 8,420 becquerel per kilogram.
Iodine-131 in Milk & Water
* Japan’s legal safety limit on radiation in water / milk: 300 becquerel per kilogram
* Amount of radiation detected in milk from Kawamata, Fukushima prefecture: 1,510 becquerel per kilogram
* Amount of radiation detected in Tochigi tap water: 77 becquerel per kilogram
* Amount of radiation detected in Tokyo tap water (Shinjuku): 1.5 becquerel per kilogram
Experts have said that the greatest health impact from Chernobyl came from the consumption of contaminated food. In that case, authorities did not properly warn people about radiation in crops, milk, meat, and water. In this case, Japanese authorities appear to be restricting the sale of contaminated food.
Even if future tests find that radiation levels have dropped, this will still probably kill the agriculture business in Ibaraki and Fukushima. One can expect that consumers will be checking the packages of vegetables at supermarkets, and avoiding anything from that region.
Although this only seems to be effecting a small region of Japan, the New York Times is speculating that this will probably make people stop buying Kobe beef and Japanese sushi.

then they said they would ban food from fukushima anyways just to be sure
now it turns out they did so because it DID exceed safety limits notably

It's only as safe as the people handling it allow it to be. One error is enough to cause a catastrophic failure.Quote:
