Another quake-hit Japan reactor in trouble: operator
- Thread starter tioliaohuat
- Start date
Many Malaysians live in landed houses instead of highrise flats or condos. There're in control of their own roofs. It's quite common to see Malaysian houses with roofs fitted with solar panels. I heard it's quite expensive and require regular cleaning and maintenance too. It's not used as main power source. It's just a backup in case of main power outage. Some households even have private electricity generators like those used in outdoor shows.
Solar energy is not in common use because its paneling requires huge land areas to harness the energy. Just like farming, expansive land area is need to farm more, no way of building up vertically. Even in the tropics, there's only half a day per day of less (in case of cloudy or raining) of useful sunlight. In the temperate regions, it gets even less with the four seasons.
surely not only TEPCO personals are involved in the fraud, govt department don't have their officials to check and confirm the reports authenticity. corruptions on both sides. ( TEPCO and govt )
cheating on this is like China Tofu buildings construction, look ok but very apt to collapse in an earthquake. very wicked doings.
This type of crooked dealings is common everywhere, even Land of the Free also has. Hopefully, Japanese people wake up, find out their govt is incompetent and put a better government in.
Nope bankers. Africans are better bonkers.Did you meant , Chinese are better bonkers ?
Africans make other races men inferior with their dick size.Africans invented bonking monkeys, that's where AIDS came from.
Nuclear rescue work halted as radiation levels rise
Posted: 16 March 2011 1136 hrs
TOKYO: The workers battling to contain the crisis at Japan's stricken Fukushima nuclear plant were all temporarily evacuated Wednesday because of a rise in radiation levels, a nuclear safety agency official said.
"Around 10:40 am (0140 GMT) we ordered the evacuation of workers... due to the rise in (radioactivity) data around the gate" of the plant, the official said at a televised press conference.
The evacuation came after Japanese TV footage showed smoke billowing from Fukushima No. 1 plant 250 kilometres (155 miles) northeast of Tokyo.
Japanese officials said later the smoke was likely to have been caused by a damaged reactor containment vessel.
A fire broke out early Wednesday at the number-four reactor there but was said to have been extinguished later.
Engineers have been grappling with a nuclear emergency since last Friday's massive earthquake and tsunami cut power to the plant and caused reactor fuel rods to heat up dangerously.
There have now been four explosions and two fires at the complex.

Japan's nuclear crisis spurs Europe to review nuclear safety
Posted: 16 March 2011 0230 hr
BERLIN : Growing alarm over Japan's nuclear disaster is prompting several European nations to review the safety of their own nuclear installations, with Germany temporarily shutting down seven reactors.
As Japan's nuclear crisis raged on Tuesday with two more blasts and a fire rocking the quake-stricken Fukushima power plant, Chancellor Angela Merkel announced a safety review of Germany's 17 nuclear reactors and a three-month closure of seven of them.
"We are launching a safety review of all nuclear reactors ... with all reactors in operation since the end of 1980 set to be idled for the period of the (three-month) moratorium," Merkel said.
In Brussels, the European Union, responding to soaring public anxiety, agreed Tuesday to conduct "stress tests" on the continent's nuclear power plants, the bloc's energy chief Guenther Oettinger said.
Oettinger said the tests would be conducted on a "voluntary" basis and would look at whether plants could resist earthquakes, tsunamis and terrorist attacks.
The agreement was reached at a meeting of ministers, national nuclear safety chiefs and industry leaders hastily called by Oettinger.
In Moscow, Prime Minister Vladimir Putin Tuesday ordered a review of the future of Russia's atomic energy sector in the wake of the earthquake and tsunami that devastated Japan.
He said that Russia did not have atomic power stations built on earthquake faultlines and had no plans to build them there. "We need to be prepared to act in any eventuality," he added.
Putin's remarks mark the first time the Russian leadership has questioned the future of nuclear energy in Russia after the Japanese earthquake, which damaged the Fukushima nuclear power plant.
Russia is one of the world's most significant producers of nuclear energy and it also builds nuclear power stations abroad.
In Britain, the government asked its chief nuclear inspector to report on what implications the Japanese nuclear crisis could have for the country's nuclear energy sector.
"We take this incident extremely seriously even though there is no reason to expect a similar scale of seismic activity in the UK," Energy Minister Chris Huhne said.
France's Foreign Minister Alain Juppe, speaking Tuesday after a Paris gathering of G8 powers, highlighted the gravity of Japan's nuclear emergency.
"The situation is extremely serious... The risk is extremely high," said Juppe, after Japan's Takeaki Matsumoto briefed him and their other G8 counterparts on the situation.
Amid heightened public concerns over France's own big nuclear power sector, Environment Minister Nathalie Kosciusko-Morizet announced safety checks on all the country's 58 nuclear power reactors.
The checks are so that "everyone can learn the lessons" from Japan's nuclear crisis centred on the quake-stricken Fukushima atomic power plant, Kosciusko-Morizet told parliament.
But French Prime Minister Francois Fillon insisted it would be absurd to condemn nuclear energy out of hand.
France is proportionally the world's biggest user of nuclear power, with 58 reactors in 19 power plants providing around 75 percent of its energy needs.
Japan's nuclear emergency also prompted Switzerland Monday to suspend plans to replace its ageing nuclear power plants, with Italy taking a hard look at its new nuclear energy plans while Poland said it would press on with building it first plants.
In Sweden, an official at the Radiation Safety Authority stressed that work to modernise the country's 10 reactors at three power stations was ongoing.
And Bulgaria said there was no plan to shut down the two operational 1,000-megawatt reactors at its single nuclear power plant at Kozloduy on the Danube, prior to their operation deadlines which expire in 2017 and 2019.
In Spain, the environmental umbrella group Ecologists in Action urged the government Tuesday to close the country's oldest nuclear reactor following the Japanese developments.
It called for a demonstration on Thursday in Madrid to demand the closure of the plant at Garona in northern Spain and for a "sensible" timetable to shut down the country's five other reactors.
Meanwhile, explosions and a fire at Japan's quake-hit nuclear plant unleashed dangerous levels of radiation Tuesday.
Radiation levels around the Fukushima No.1 plant on the eastern coast had "risen considerably", Japanese Prime Minister Naoto Kan said, and his chief spokesman announced it had reached the point where it endangered human health.

6.0-aftershock strikes Chiba
TOKYO: A strong 6.0-magnitude aftershock struck in the Pacific just off Chiba prefecture, the Japan Meteorological Agency said, with the force strong enough to sway buildings in Tokyo.
The quake struck in the Pacific off Chiba prefecture -- 96 kilometres (60 miles) east of the capital -- and was felt across large areas of eastern Japan, the USGS said.
There were no reports of injuries or damage following the tremor, which struck at a shallow depth of 25 km at 12:52 pm (0352 GMT), police and local government officials said.
No tsunami warning was issued but the Japan meteorological agency warned of a possible change in sea levels.
Japan had been experiencing a series of aftershocks since a massive 9.0-magnitude earthquake -- which resulted in a powerful tsunami -- hit the northeast coast of Japan of Friday.
Japanese officials said on Sunday the country faces a "70 per cent" possibility of a 7.0-magnitude aftershock.
"There is a 70 per cent possibility that an aftershock with a magnitude of seven or more will occur" within the next three days, said Takashi Yokota, director of earthquake prediction and information at the Japan Meteorological Agency.
"The possibility is 50 per cent" during the three days from March 16, he added, pointing out that strong aftershocks have continued since Friday's quake and tsunami.
Authorities said more than 11,000 people were dead or missing amid the disaster.

Take diesel for instance. Because of research in the last twenty years, it is a different fuel we know from the 80s. It is in fact, cleaner, more powerful and cheaper than the petrol we get in regular pump stations. Yet the government restricts diesel powered private cars.
Why?
This is true. There are already inventions to generate electricity from alternative fuels like soya bean oil,. But the technology is always bought out before further research is halted.
Diesel tax is lower than petrol tax. If tax are same the price will be only 10% different.
there are a few reason why research using food product as alternative fuel was so slow. firstly not economically feasible as energy product per mass of biofuel vs petrol/diesel has a great difference. however one of the concern was the danger of cutting down on food supply to meet the energy demand.
if you think bio-fuel burn cleaner or greener, you might get a shock if you look at recent studies. large farm area needed, burn less effectively producing more CO2, waste product during the extraction process. it was not as simple as what was being advertised by these green group. majorities of them never goes to school anyway and believed blindly what others told them without looking further.
Fukushima: History of "cover-ups"
Well before the present Fukushima nuclear power plant emergency, the Tokyo-based Citizens Nuclear Information Centre had reported about a history of “cover-ups” in the Japanese nuclear energy industry.
The cover-ups included data falsification during voluntary site inspections and attempts to camouflage damage. “There have been a growing number of damage cover-ups and data falsifications around 1994 when electric companies had started shortening the time for a periodical inspection having learned from the ‘success’ experience in the US,” said the CNIC.
Among the plants included in the report were the Fukushima I plant.
The NISA and the TEPCO published interim reports on September 13 and 17 (2002) respectively, which addressed the 29 suspected cases in more detail. Regarding the cracks detected in the core shroud, according to the report, they had been already found at Fukushima I Unit-1 and Unit-4 in 1993, where the cracks in the middle part of the shroud at Fukushima I Unit-2 in 1994 were reported officially as the first case. The magnitude of the cracks in Fukushima I Unit-2 turned out to be far greater and more serious than the ones announced by the official report. It has also become clear that reactors in Fukushima I Unit 1, 3, and 5 have cracks in each shroud, so the claim that no cracks were found in the core shrouds and that they were replaced as a “preventive measure” is completely false.
See the report on the CNIC website. http://cnic.jp/english/newsletter/nit92/nit92articles/nit92coverup.html

Exactly. They are like robots working in a factory - doing the same and being expendable.
But they are definitely better than useless, smelly, backstabbing, ugly kelings who will kill their own kind. Yes shoot the ah neh instead of the snakes.
Japan choppers dump water on stricken atomic plant
Posted: 17 March 2011 1613 hrs
TOKYO: Japanese military helicopters dumped tonnes of water Thursday onto the stricken Fukushima nuclear power plant northeast of Tokyo in a bid to douse fuel rods and prevent a disastrous radiation release.
Four twin-rotor CH-47 Chinooks of the Self-Defence Forces ran the first mission to empty large buckets that hold more than seven tonnes of water each onto the facility damaged by Friday's massive earthquake and tsunami.
The operation aims to keep the fuel rods inside reactors and containment pools submerged under water, to stop them from degrading when they are exposed to air and emitting dangerous radioactive material.
The helicopter mission started in the morning under a clear sky after a similar effort the previous day was called off shortly before darkness fell by officials citing strong radiation and high winds.
Police water cannon were also set to support the effort Thursday in addition to equipment already in use over recent days at the plant, some 250 kilometres (155 miles) northeast of the Japanese capital.
Defence Minister Toshimi Kitazawa said an additional 11 military vehicles would be deployed for efforts to help cool the reactors, while pumps supplied by the US armed forces were also being transferred.
The government's nuclear safety agency has said the top priority should be pouring water into the fuel-rod pools at reactors three and four, which may be boiling and are not fully covered by roofs that would reduce radiation leaks.
An official at plant operator Tokyo Electric Power Co (TEPCO) said Thursday the pool at the number-four reactor "seemed to have water" on Wednesday, based on aerial observations carried out by the military helicopters.
Another TEPCO spokesman said: "We have not confirmed how much water was left inside but we have not had information that spent fuel rods are exposed."
TEPCO said earlier it was concentrating on restoring the power supply to reactivate its crippled cooling systems, which were knocked out in the dual calamity that hit Japan.
"We cannot tell when, but we want to restore the power source as soon as possible," TEPCO spokesman Naohiro Omura told AFP.
TEPCO was preparing to restore outside power lines from Tohoku Electric Power Co., which serves the region, and connect its damaged electric transmission system with unaffected lines.
"At the moment, we are concentrating our efforts on this work," the spokesman said.
"If the restoration work is completed, we will be able to activate various electric pumps and pour water into reactors and pools for spent nuclear fuel."
The 9.0-magnitude quake, the biggest on record to strike Japan, knocked down electricity pylons which Tohoku had used to supply power to the TEPCO plant.
Some 70 workers have been using pumps to pour seawater to cool reactors at the plant, according to media reports, using electricity from borrowed mobile generators.
In Fukushima prefecture, where a zone within 20 kilometres of the plant has already been evacuated, about 10,000 people were to be screened at 26 locations for radiation exposure, Kyodo News reported, citing local officials.
So far, radioactivity was detected on six people, whose faces and hands were wiped clean, the report said.
