Tata Power to build India's first floating solar plant

Mumbai, Mar 22: Tata Power today said it will be building the country's first low-cost, high-efficiency floating solar plant in partnership with an Australian company which invented the technology.

Sunengy, the Australian company, and Tata Power will begin constructing a pilot plant that uses the Liquid Solar Array (LSA) technology from August this year, a press release issued here said.

LSA uses traditional concentrated photovoltaic technology but rather than mounting the cells on a frame, it is made to float on water, making it low-cost, cyclone-proof and less tedious as it does not involve any land acquisition, it added.

"It effectively turns a dam into a very large battery, offering free solar storage and opportunity for improved water resource management," the inventor of the technology and Sunengy's Executive Director and Chief Technology Officer, Phil Connor, said.

Tata Power's Executive Director, Banmali Agrawala, confirmed the tie-up for the "nascent technology" and said this is a part of the company's effort to invest in clean and eco-friendly technologies.

Radioactive substances in seawater near Japan plant

Osaka, Mar 22: High levels of radioactive substances have been detected in seawater near a quake-crippled nuclear power plant in Japan, its operator said early today.

The substances were detected in seawater which was sampled yesterday about 100 metres south of the Fukushima No 1 plant, a Tokyo Electric Power Co (TEPCO) official said, stressing it was not a threat to human health.

"Normally, such radioactive substances are not detected in the area," said Naoki Tsunoda, adding that the company will continue monitoring at the same point and in other areas.

TEPCO said the level of iodine-131 was 126.7 times higher and caesium-134 was 24.8 times higher than government-set standards.

The level of caesium-137 was also 16.5 times higher while that of cobalt-58 was lower than the standard, said Tsunoda.

A 9.0-magnitude quake and ensuing tsunami on March 11 devastated Japan''s northeastern Pacific coast, knocking out the plant's cooling systems and leaving it on the brink of a catastrophic meltdown.

Helicopters and fire trucks have been deployed to pour water over heating fuel rods at the plant since Thursday.

New blasts, fire at nuke plant in disaster-hit Japan

Sendai, Mar 15: Japan's nuclear crisis escalated today (Mar 15) as two more blasts and a fire rocked a quake-stricken atomic power plant, sending radiation up to dangerous levels.

Radiation around the Fukushima No.1 plant on the eastern coast had "risen considerably", Prime Minister Naoto Kan said, and his chief spokesman announced the level was now high enough to endanger human health.

In Tokyo, some 250 kilometres to the southwest, authorities also said that higher than normal radiation levels had been detected in the capital, the world's biggest urban area, but not at harmful levels.

Kan warned people living up to 10 kilometres beyond a 20 km exclusion zone around the nuclear plant to stay indoors.

The fire, which was later reportedly extinguished, was burning in the plant's number-four reactor, he said, meaning that four out of six reactors at the facility are now in trouble.

As well as the atomic emergency, Japan is struggling to cope with the enormity of the damage from Friday's record-breaking quake and the tsunami which raced across vast tracts of its northeast, destroying all before it.

The official death toll has risen to 2,414, police said today, but officials say at least 10,000 are likely to have perished.

The crisis at the ageing Fukushima plant has escalated daily after Friday's quake and tsunami which knocked out cooling systems.

On Saturday an explosion blew apart the building surrounding the plant's number-one reactor. On Monday, a blast hit the number-three reactor, injuring 11 people and sending plumes of smoke billowing into the sky.

Early today a blast hit the number-two reactor. That was followed shortly after by a hydrogen explosion which started a fire at the number-four reactor.

Chief government spokesman Yukio Edano said radioactive substances were leaked along with the hydrogen.

"What we most fear is a radiation leak from the nuclear plant," Kaoru Hashimoto, 36, a housewife living in Fukushima city 80 kilometres northwest of the stricken plant, told AFP by phone.

"Not much confirmed information is coming to us, so we are in trouble about how to cope with the situation." Hashimoto said supermarkets are open but shelves are completely empty. "Many children are sick in this cold weather but pharmacies are closed. Emergency relief goods have not reached evacuation centres in the city.

"I'm wondering how long we can manage with the food we have in stock. Everyone is anxious and wants to get out of town. But there is no more petrol. We are afraid of using a car as we may run out of petrol."

The UN's nuclear watchdog, the International Atomic Energy Agency, said Tokyo had asked for expert assistance in the aftermath of the quake which US seismologists are now measuring at 9.0-magnitude, revised up from 8.9.

But the IAEA's Japanese chief Yukiya Amano moved to calm global fears that the situation could escalate to rival the world''s worst nuclear crisis at Chernobyl in the Ukraine in 1986.

"Let me say that the possibility that the development of this accident into one like Chernobyl is very unlikely," he said.

Officials have already evacuated 210,000 people in the exclusion zone around the crippled plant.

At one shelter, a young woman holding her baby told public broadcaster NHK: "I didn't want this baby to be exposed to radiation. I wanted to avoid that, no matter what."

Further north in the region of Miyagi, which took the full brunt of Friday's terrifying wall of water, rescue teams searching through the shattered debris of towns and villages have found 2,000 bodies. And the Miyagi police chief has said he is certain more than 10,000 people perished in his prefecture.

Millions have been left without water, electricity, fuel or enough food and hundreds of thousands more are homeless and facing harsh conditions with sub-zero temperatures overnight, and snow and rain forecast.

Tokyo stocks, which were punished Monday when the markets reopened, sending indexes around the world sliding, plummeted another 12 per cent by early afternoon today.

Panic selling saw stocks close more than six per cent lower in Tokyo yesterday on fears for the world's third-biggest economy, as power shortages prompted rolling blackouts and factory shutdowns in quake-hit areas.

Kaori Ohashi, 39, a mother-of-two working in a nursing home for the elderly near the city of Sendai, spent two nights trapped in the building after its first floor was submerged by the tsunami.

"Snow started to fall and it became dark. We lost power. I thought ''This is a nightmare," Ohashi told AFP after she was rescued.

At least 1.4 million people in Japan were temporarily without running water and more than 500,000 were taking shelter in evacuation centres, said the UN's Office for the Coordination of Humanitarian Affairs.

At a hospital in the fishing town of Kesennuma hit by the tsunami, an official said basic supplies were desperately needed.

"We are critically short of water," he said. "Water is very important here. To save it, we need a lot of disposable dishes. We need blankets as well." Aid workers and search teams from across the world joined 100,000 Japanese soldiers in a massive relief push as the country suffers a wave of major aftershocks.

Leading risk analysis firm AIR Worldwide said the quake alone would exact an economic toll estimated at between USD 14.5 billion and USD 34.6 billion -- even leaving aside the effects of the tsunami.

3rd explosion at nuclear plant jolts Japan; death toll rises

Tuesday, March 15, 2011, 7:52 [IST]Print This PageExplosion in JapanTokyo, Mar 15: Japanese government is struggling to cease meltdown in nuclear power plants from last four days but blasts, one after another, increased their miseries. Another nuclear blast in Fukushima Daiichi Nuclear Power Station shattered Japan once again on the wee hours of Tuesday (Mar 15) morning.

Tuesday's blast, which is counted as the third continuous blast in the nuclear plant, reportedly occurred at the No 2 reactor in Fukushima. The recent blast is believed to have hit each of the three crippled reactors at the plant.

Tokyo Electric Power Co officials informed that the latest blast happened near a suppression pool, which removes heat under a reactor vessel. Sources reported that the recent explosion injured 15 workers and military personnel and exposed up to 190 people to elevated radiation.

The first explosion at the nuclear plant happened on Saturday, Mar 12 following a massive earthquake and tsunami just a day before. Japanese news agency Kyodo on Sunday reported that the cooling system had stopped working in a sixth reactor. Watch Japan Tsunami Videos.

Soon after the first explosion, Japan ordered to evacuate almost 180,00 people from the area near the damaged nuclear power plant, informed the UN nuclear watchdog.

Then on Monday, another Hydrogen blast crippled the region when a massive column of smoke was seen belching from the plant's No 3 unit. However, sources informed that the reactor, previously, was under emergency watch for a possible explosion.

The total death toll in the country is feared to have crossed 10,000. After the nuclear explosions, up to 160 may have been exposed to radiation, sources confirmed.
