The possibly failed salt cavern may be closer to the outer wall of the Napoleonville Dome than Texas Brine officials believed.• DNR defended the timing of its disclosures about the history surrounding the salt cavern as matching the emerging facts of the incidents in Bayou Corne.• Sonny Cranch, Texas Brine spokesman, said company officials have been as surprised as anyone about a possible collapse of their salt cavern.• DNR officials allowed Texas Brine to deposit naturally-occurring radioactive material arising from drilling into two company salt caverns, including the one that may have breached in the Bayou Corne area. As of Wednesday, state environmental officials had not tested the sinkhole for radioactivity."

Friday evening, the day the sinkhole developed and released a foul diesel odor was the first time DNR officials made public information indicating that the cavern may have failed and caused the sinkhole, a “slurry area.” Tuesday night, DNR and Texas Brine officials explained that the cavern appeared closer to Napoleonville Dome’s edge than thought when the cavern was issued a state permit 1982, and that the cavern wall might have been breached. That failure could allow a connection between the cavern’s brine contents and sediments around the dome.

Ball said DNR officials focused on locating a source of the natural gas large enough to send gas bubbling up in the bayous and they focused on area natural gas pipelines and two salt caverns known to be storing natural gas under pressure.

SIMI VALLEY, Calif. (AP) — Lingering radioactive contamination exists at a former rocket test lab outside of Los Angeles that was the site of a partial nuclear meltdown, federal environmental regulators said Wednesday. The Environmental Protection Agency launched a $42 million study to investigate radioactive pollution at the Santa Susana Field Laboratory, 25 miles northwest of downtown Los Angeles. Technicians collected 3,735 soil samples from a corner of the 2,850-acre hilltop lab where most of the testing was done. Of those, they found about 10 percent contained radioactive concentrations exceeding background levels. Most of the contaminated soil was found in places like the materials handling facility that were previously cleaned, but it looked like "isolated spots were missed," said Mary Aycock, an EPA Superfund remedial project manager.

Radioactive cesium was detected from two minke whales caught off the coast of Kushiro, Hokkaido, in Japan's so-called research whaling, a whalers' association said Tuesday.

While the level of the radioactive material remained below the temporarily set upper limit, the association officials said during a press conference in Kushiro that the contamination must have been caused by the continuing nuclear crisis at the Fukushima Daiichi power plant and that they will closely monitor future developments.

During the research whaling that started in late April, 17 whales were caught, and researchers examined six of them. Of the six, two were found tainted with 31 becquerels and 24.3 becquerels of cesium per kilogram of whale meat, they said.

The discovery of radioactive tissue boxes at Bed, Bath & Beyond Inc. (BBBY) stores in January raised alarms among nuclear security officials and company executives over the growing global threat of contaminated scrap metal.

While the U.S. home-furnishing retailer recalled the boutique boxes from 200 stores nationwide without any reports of injury, the incident highlighted one of the topics drawing world leaders to a nuclear security meeting in Seoul on March 26-27. The bi-annual summit, convened by President Barack Obama for the first time in 2010, seeks to stem the flow of atomic material that has been lost, stolen or discarded as trash.

As U.S. and European leaders tackle the proliferation of weapons-grade uranium or plutonium in countries like Iran and North Korea, industries are confronting the impact of loose nuclear material in an international scrap-metal market worth at least $140 billion, according to the Brussels-based Bureau of International Recycling. Radioactive items used to power medical, military and industrial hardware are melted down and used in goods, driving up company costs as they withdraw tainted products and threatening the public’s health. ‘Major Risk’ “The major risk we face in our industry is radiation,” said Paul de Bruin, radiation-safety chief for Jewometaal Stainless Processing BV, one of the world’s biggest stainless- steel scrap yards. “You can talk about security all you want, but I’ve found weapons-grade uranium in scrap. Where was the security?”

Radioactive contamination at the Treasure Island Naval Station, where San Francisco plans to build a high-rise community for 20,000 residents, is more widespread than previously disclosed, according to a new U.S. Navy report and other documents obtained by The Bay Citizen.

The draft report, dated Aug. 6, marks the first time the Navy has fully acknowledged that the island, created from landfill in 1937, was used as a repair and salvage operation for a Pacific fleet exposed to atomic blasts during the Cold War. The report came in response to state regulators, who pressed for details after cleanup workers found radioactive waste in unexpected locations.

Known potential sources of radiation on the island included a nuclear training ship intentionally doused in radiation and even glow-in-the-dark buttons handed out at the 1939-1940 Golden Gate International Exposition held on the island.

Continued flooding does threaten the plants, however. As nuclear engineer Arnie Gundersen explains in the above video, cooling pumps must operate continuously, even years after a plant is shut down. One group, the Foundation for Resilient Societies, has proposed solar panels and other high-reliability power sources to supply backup cooling for the fuel pools at nuclear plants.

While hindsight might be 20/20, the lack of foresight can be blindingly deadly when it comes to radioactive waste that lasts tens of thousands of years for the measly prize of 40 years of electricity.

“Ft. Calhoun is the designated spent fuel storage facility for the entire state of Nebraska…and maybe for more than one state. Calhoun stores its spent fuel in ground-level pools which are underwater anyway – but they are open at the top. When the Missouri river pours in there, it’s going to make Fukushima look like an x-ray.
