Nuclear Event in USA on Tuesday, 27 September, 2011 at 03:09 (03:09 AM) UTC.

Quote
Entergy’s Palisades nuclear plant near South Haven is venting radioactive steam into the environment as part of an unplanned shutdown triggered by an electrical accident. This shutdown, which began Sunday evening, came just five days after the plant restarted from a shutdown that was caused by a leak in the plant’s cooling system. Nuclear Regulatory Commission spokeswoman Prema Chandrithal said that the current shutdown happened because an object slipped during work on a circuit breaker and caused an arc that took out power for one of two DC electrical systems that power safety valves and other devices. According to a notice filed with the Nuclear Regulatory Commission, the plant is stable and “controlling temperature using Atmospheric Dump Valves.” “The steam that would normally go to the generators, that steam is now going into the environment … through the steam stack,” said Chandrithal.

This is deep Zorgon, I just hope this isnt to dangerous for the inhabitants near it and the environment surrounding.  It seems these days radiation isnt taken as serious/fearful as it was in the past. 
-1 LIGHT* amongst many within the kingdom of dark.  Far off in the distance all that's seen is a SPARK! 

-Some say why do you care about these VIBRATIONS - I say awaken the 3rd eye and lets establish communications..

too frequent accidents make it seem as system's failures of safety.

Radioactive steam? Oh nothing to worry about.
 

Hmmm well then  how about THIS?

Radioactive water released into river at Grand Gulf
Published 12:00am Wednesday, May 4, 2011


PORT GIBSON — An unknown amount of radioactive water was released accidentally into the Mississippi River late last week at the Grand Gulf Nuclear Station.

The Nuclear Regulatory Commission is investigating the incident, but suggests the release poses no public health hazard.

Entergy Nuclear, which operates Grand Gulf, filed a report with the NRC explaining that crews located standing water at the plant last week after the area experienced heavy rains.

Water was found Thursday at the Unit 2 turbine building — which is an abandoned, partially constructed building — and began pumping the water into the river.

An alarm apparently alerted workers to the presence of tritium, a byproduct of the nuclear reactor processes. The pumps were turned off stopping the flow. Investigators are not certain why tritium was in the storm water or how it got there.

“Although the concentrations of tritium exceeded EPA drinking water limits, the release should not represent a hazard to public health because of its dilution in the river,” said Lara Uselding, public affairs officer with the U.S. Nuclear Regulatory Commission, Region IV.

Maybe they can catch Glofish...  that new delicacy in Japanese restaurants

Yes there have been too many close calls lately that barely make the news. Even the Fukushima case is hardly mentioned, if at all and that is still on going. And I think they still haven't started on that new cover for Chernobyl yet, but I haven't checked on that in a while

Fort Calhoun Nuclear Plant: 06/27/11
Flood Seeps Into Turbine Building At Nebraska Nuke Station




Quote
BLAIR, Neb. — The nation's top nuclear power regulator said Monday that both of Nebraska's nuclear power plants have remained safe as they battle floodwaters from the bloated Missouri River.

Nuclear Regulatory Commission Chairman Gregory Jaczko visited both Fort Calhoun and Cooper nuclear power plants in eastern Nebraska this week to see how the utilities that run them are coping with the flooding. Both plants sit on the river.

The Omaha Public Power District's Fort Calhoun is the subject of more public concern because the floodwaters have surrounded that plant and forced workers to use elevated catwalks to access the facility. Nebraska Public Power District's Cooper plant is more elevated.

Flood berm bursts at Nebraska nuclear plant
June 26, 2011


Quote
A water-filled berm protecting a nuclear power plant in Nebraska from rising floodwaters collapsed Sunday, according to a spokesman, who said the plant remains secure.

Some sort of machinery came in contact with the berm, puncturing it and causing the berm to deflate, said Mike Jones, a spokesman for the Omaha Public Power District (OPPD), which owns the Fort Calhoun plant.

The plant, located about 20 miles north of Omaha, has been shut since April for refueling.

"The plant is still protected. This was an additional, a secondary, level of protection that we had put up," Jones said. "The plant remains protected to the level it would have been if the aqua berm had not been added."

Recent Biotechnology Innovation
Is a Bit Fishy: A Fluorescent Pet


Oh and you thought I was JOKING about the Glofish huh? Well I found these on a whim when I searched for Glofish to go with the article... didn't expect to find genetically altered fish that glow green  :o



Quote
TAIPEI, Taiwan -- In the basement of a building down an alley here floats the future of bioengineered pets, and it is glowing.

In a corner, small fish flit about in a dozen aquariums. Bill Kuo, a manager at Taikong Corp., draws a thick curtain and switches on black lights over the tanks. Suddenly, the fish glow a bright green. "Imagine you come home from work, turn out the lights and look at these," Mr. Kuo says. "It's very relaxing."

Fluorescent fish are just one of the latest off-the-wall innovations to come along in the biotechnology march. American researchers are seeking approval for a super-size salmon, retooled with growth hormones. A Canadian company, Nexia Biotechnologies Inc., is injecting spider genes into goats to produce milk that can be refined and woven into "BioSteel," for use in surgical sutures and "ballistic protection," the company says. Another Canadian group has trademarked the name "EnviroPig" for its genetically modified swine, whose manure contains fewer phosphates, a natural pollutant.

But Taikong's fish, which hit the market in Taiwan last month, may well be the world's first genetically modified house pets -- certainly the first designed to glow in the dark and one of the first leisure-time applications for genetic engineering. Born in a Taiwan biologist's lab in 2001 and written up in a scientific journal, the fish were soon discovered by Taikong, a 20-year-old company that sells aquarium equipment and fish food to shops around the world.

Quote
A group of nuclear weapons designers and scientists at the Lawrence Livermore National Laboratory conducted a what-if experiment several years ago, deploying supercomputers to simulate what happens to a nuclear weapon from the moment it leaves storage to the point when it hits a target.

They methodically worked down a checklist of all the possible conditions that could affect the B-83 strategic nuclear bomb, the most powerful and one of the most modern weapons in the U.S. arsenal, officials said. The scientists and designers examined how temperature, altitude, vibration and other factors would affect the bomb in what is called the stockpile-to-target sequence.

Such checks typically have been carried out by taking bombs and warheads apart; scrutinizing them using chemistry, physics, mathematics, materials science and other disciplines; and examining data from earlier nuclear explosive tests. This time, however, the scientists and designers relied entirely on supercomputer modeling, running huge amounts of code.

Then came a surprise. The computer simulations showed that at a certain point from stockpile to target, the weapon would “fail catastrophically,” according to Bruce T Goodwin, principal associate director at Livermore for weapons programs. Such a failure would mean that the weapon would not produce the explosive yield expected by the military — either none at all, or something quite different than required to properly hit the target.
