California 'closely monitoring' Japan nuclear leak

Mon, 2011-03-14 10:24 — Katie Rast

LOS ANGELES (AFP) – California is closely monitoring efforts to contain leaks from a quake-damaged Japanese nuclear plant, a spokesman said Saturday, as experts said radiation could be blown out across the Pacific.

While officials downplayed any immediate danger, the US Nuclear Regulatory Commission deployed two experts to Japan, where the Fukushima plant, which was rocked by a large explosion earlier in the day in the aftermath of Japan's strongest-ever earthquake.

"At present there is no danger to California. However we are monitoring the situation closely in conjunction with our federal partners," Michael Sicilia, spokesman for California Department of Public Health, told AFP.

"California does have radioactivity monitoring systems in place for air, water and the food supply and can enhance that monitoring if a danger exists," he added.

Fukushima Dai-ichi nuclear reactor in Japan suffers 2nd explosion

Mon, 2011-03-14 10:00 — Katie Rast

Monday, March 14th 2011, 9:36 AM

A second hydrogen explosion rocked a crippled Japanese nuclear reactor Monday, spewing a giant cloud of smoke into the air and injuring 11 workers, officials said.

The blast was so large it could be felt 25 miles away.

The plant's operator, however, insisted that radiation levels around the facility remained within legal limits.

A similar explosion was triggered Saturday at the Fukushima Dai-ichi reactor after cooling systems were damaged by Friday's earthquake and tsunami.

Officials said a separate damaged reactor at the facility was also experiencing severe problems after its fuel rods became fully exposed, raising the risk of overheating and yet another explosion.

A state of emergency has been declared at six reactors where cooling systems and backup generators failed following Friday's twin disasters.

Winds at Japan Power Plants Should Send Radiation out to Sea

Mon, 2011-03-14 09:36 — Katie Rast

Three reactor units at the Onagawa plant are being watched and controlled for radiation leaks and possible meltdown.

The wind direction may impact where the radiation goes both at a local level and even across the globe. The wind direction at both of these locations are similar since the Onagawa power plant is located just to the northeast of Fukushima power plant.

"The exact direction of the winds would have to be known at the time of the release of a large amount of radiation to understand exactly where the radiation would go," according to Expert Senior Global Meteorologist Jim Andrews.

It is unknown when a large release of radiation would occur, if at all, at this point.

"You can calculate how long the release of a radiation would take to cross the Pacific from Japan to the U.S. by choosing different speeds that the radioactive particles might be moving and using the direct distance between given locations- say Sendai, Japan, and Seattle, Wash.," Andrews added.

Japan may hand out iodine near nuclear plants: IAEA

VIENNA | Sat Mar 12, 2011 11:59am EST
Japanese authorities have told the U.N.'s atomic watchdog they are making preparations to distribute iodine to people living near nuclear power plants affected by Friday's earthquake, the Vienna-based agency said.
