U.S. nuclear regulators probing leak at Honeywell uranium plant BY LEWIS KRAUSKOPF Tue Oct 28, 2014 Oct 28 (Reuters) – U.S. nuclear regulators are investigating a leak of uranium hexafluoride that occurred on Sunday at an Illinois plant operated by Honeywell International Inc where union workers have been locked out.
Honeywell confirmed the Sunday evening leak at its Metropolis, Illinois plant, saying it was due to an equipment failure. There were no injuries and no reason to believe anyone was endangered by the leak, according to Honeywell.
An inspector from the Nuclear Regulatory Commission started an investigation at the plant on Tuesday, said NRC spokesman Roger Hannah.
“At this point we’re still in a fact-finding mode,” Hannah said. “We haven’t come to any conclusions about whether processesweren’t followed.” He said the investigation could take a few days to a week. Honeywell’s Metropolis plant is the only U.S. facility that converts uranium oxide into to uranium hexafluoride, or UF6, which is then enriched to be used as fuel in nuclear power plants.
Uranium hexafluoride is radioactive, and if released into the air can be chemically toxic……..http://www.reuters.com/article/2014/10/28/honeywell-intl-uranium-idUSL1N0SN0ZX20141028
Contractor Submitted False Radiation Data at Hunters Point, NBC Bay Area In an internal report uncovered by the Investigative Unit, Tetra Tech says it provided the Navy false soil samples while working on the radiological cleanup of the Hunters Point shipyard By Vicky Nguyen, Liz Wagner and Felipe Escamilla Monday, Oct 13, 2014
A Navy contractor tasked with cleaning radioactive soil at the Hunters Point Naval Shipyard in San Francisco admitted in an internal report obtained exclusively by the NBC Bay Area Investigative Unit that it mishandled soil samples and submitted false data.
Tetra Tech, a multinational engineering, construction and environmental corporation details in an April 2014 report how it was caught submitting false soil samples to the Navy in an apparent effort to declare the soil free of radiological contamination when it may not have been. The Pasadena-based company is a $2.7 billion per year business that has won more than $300 million worth of contracts for cleanup work at Hunters Point………
“If the Navy had not caught this,” Bowers said, “there would be very, very high levels of contaminated soil, radioactive soil in the ground, where the plans are in place to build homes for the general public to live in, with yards for children to play in.”
Bowers is one of four radiation specialists who blew the whistle on Tetra Tech’s practices and are now suing the company for retaliation, claiming they were fired after questioning the company’s actions. Bowers first spoke with the Investigative Unit earlier this year saying the cleanup of Hunters Point had been compromised and that Tetra Tech cut corners on safety to save money……..http://www.nbcbayarea.com/investigations/Contractor-Submitted-False-Radiation-Data-at-Hunters-Point-279025911.html

Workers drop refueling crane console into Fukushima Daiichi Reactor 3 spent fuel pool Enformable, 29 Aug 2014 The workers were carrying out operations to remove debris with a large remote controlled crane. At the time of the accident, workers were manipulating the control console for the refueling machine, a piece of equipment that weighs almost a thousand pounds.At the crippled Fukushima Daiichi nuclear power plant, workers accidentally dropped a large piece of debris into the Unit 3 spent fuel pool on Friday, a little after noon.
TEPCO is working to check the 566 spent fuel assemblies in the Unit 3 spent fuel pool to see if any of them have been damaged by the most recent accident. According to decommissioning plans, the utility is scheduled to start removing spent fuel rods from the Unit 3 spent fuel pool in the first half of 2015 at the earliest.Tokyo Electric, who is in charge of cleanup operations at Fukushima Daiichi, told reporters that they have not detected any change in radiation levels around the spent fuel pool after the accident.
This is not the first time that debris and large objects have been accidentally dropped, pulled, or pushed into the Unit 3 spent fuel pool. Between 2012 and 2013, TEPCO workers used the remote control cranes to remove debris from atop the Unit 3 reactor building, and multiple instances were recorded where operators moving cranes via remote control knocked debris into the spent fuel pool or dislodged other materials on the roof.
In February 2013, workers accidentally knocked the 1.5 ton fuel handling machine mast into the Unit 3 spent fuel pool, and it was later found to have come to rest on top of the spent fuel racks after it narrowly avoided damaging the liner of the spent fuel pool.

Tepco Says 400-Kg Control Console Fell Into Fukushima Fuel Pool Bloomberg, By Emi Urabe and Peter Langan Aug 29, 2014 Tokyo Electric Power Co. (9501) said it’s detected no change in radiation levels in the Fukushima Dai-Ichi No. 3 reactor building after a 400 kilogram piece of equipment slipped from a crane and fell back into a pool holding spent uranium fuel rods.
The accident happened at around 12:45 p.m. today as the company was attempting to move what it described as a crane control console, according to a statement on its website.
The console, which is about a meter wide and 1.6 meters high, was blown into the pool on March 14, 2011, when the No. 3 reactor building exploded following an earthquake and tsunami that wrecked the Fukushima plant.
Today, the utility known as Tepco was attempting to move the device as part of its cleanup at the site, said spokesman Hiroshi Itagaki. …….http://www.bloomberg.com/news/2014-08-29/tepco-says-400-kg-control-console-fell-into-fukushima-fuel-pool.html
Israeli stealth drone downed at nuclear facility, Iran claims Revolutionary Guard hails act against ‘warmongers’ as incident reported at major uranium enrichment plant Harriet Sherwood in Jerusalem and Saeed Kamali Dehghan in Boston The Guardian, Monday 25 August 2014 Iran‘s Revolutionary Guards claimed on Sunday that an Israeli stealth drone had been brought down above the Natanz uranium enrichment site in the centre of the country.
The semi-official Fars news agency reported that Iran’s elite forces had intercepted and brought down an unmanned aircraft belonging to “the Zionist regime”. The news was announced in a statement published by the guards, but it was not clear when the incident, if true, happened.
“This mischievous act once again reveals the adventurist nature of the Zionist regime [of Israel] and added another black page to this fake and warmongering regime’s file which is full of crimes,” said the Revolutionary Guards’ statement.
The state news agency ISNA reported that the aircraft was “of the stealth, radar-evasive type and it intended to penetrate the off-limits nuclear area in Natanz … but was targeted by a ground-to-air missile before it managed to enter the area.”
A spokesman for the Revolutionary Guards later told Iranian television that parts of the aircraft had been retrieved. Iran claimed to have reverse engineered a drone after capturing an American RQ-170 Sentinel in 2011.
“Major parts of the devices of the drone are intact and have been received by our friends that can be used for further information,” said General Ramazan Sharif. He did not say when the aircraft was shot down, but said it was “identified upon arrival in Iranian airspace”. He said authorities allowed it to fly for a short time to determine its destination.
Israeli political and military officials said they never respond to such claims. They have repeatedly threatened to take military action against Iran’s nuclear installations, but have been reluctant to do so without US backing or participation.
Natanz is Iran’s main uranium enrichment site, housing more than 16,000 centrifuges. About 3,000 more are at the Fordo plant, buried inside a mountain and hard to destroy…….. http://www.theguardian.com/world/2014/aug/24/israeli-stealth-drone-nuclear-facility-iran-natanz
Cause of New Mexico nuclear waste accident remains a mystery , LA Times, By RALPH VARTABEDIAN contact the reporter 24 Aug 14 A 55-gallon drum of nuclear waste, buried in a salt shaft 2,150 feet under the New Mexico desert, violently erupted late on Feb. 14 and spewed mounds of radioactive white foam.
The flowing mass, looking like whipped cream but laced with plutonium, went airborne, traveled up a ventilation duct to the surface and delivered low-level radiation doses to 21 workers.
The accident contaminated the nation’s only dump for nuclear weapons waste — previously a focus of pride for the Energy Department — and gave the nation’s elite ranks of nuclear chemists a mystery they still cannot unravel.
Six months after the accident, the exact chemical reaction that caused the drum to burst is still not understood. Continue reading

Nuclear watchdog requests safety checks after B.C. mine breach CTV News, Dene Moore, The Canadian Press August 19, 2014 VANCOUVER -- A toxic spill from a British Columbia mine has prompted the country’s nuclear watchdog to request a series of checks at uranium facilities.
The Canadian Nuclear Safety Commission will discuss the failure of the tailings pond at the Mount Polley gold and copper mine during a meeting Wednesday.
In the interim, the commission has asked the uranium mining and milling operations it oversees to ensure that all necessary inspections and monitoring are in compliance with licence conditions……..
The breach sent 10 million cubic metres of waste water and 4.5 million cubic metres of silt into a network of salmon-bearing lakes and rivers near Likely, 600 kilometres northeast of Vancouver.

Belgian Doel 4 nuclear reactor closed till year-end Major turbine damage forces closure till year-end By Geert De Clercq PARIS, Aug 14 (Reuters)
* GDF Suez confirms outage was due to sabotage
* Other reactors down, Belgian nuclear capacity halved
* Further outage set to impact GDF Suez earnings (Adds GDF Suez quote on sabotage, detail on capacity)
- Belgian energy company Electrabel said its Doel 4 nuclear reactor would stay offline at least until the end of this year after major damage to its turbine, with the cause confirmed as sabotage.
On Tuesday, Electrabel had said the plant would remain offline until Sept. 15 as it carried out repairs and investigated an oil leak that forced its closure on Aug. 5. Its French parent company GDF Suez confirmed the closure was due to sabotage.
The shutdown of Doel 4’s nearly 1 gigawatt (GW) of electricity generating capacity as well as closures of two other reactors (Doel 3 and Tihange 2) or months because of cracks in steel reactor casings adds up to just over 3 GW of Belgian nuclear capacity that is offline, more than half of the total.
The latest closure will put further pressure on the earnings of GDF Suez, which warned last month that the closure of the first two Belgian plants would push its 2014 group net recurring income to the lower end of its forecast range of 3.3 billion to 3.7 billion euros.
The French company said those outages would have an impact of about 40 million euros per month on net recurring income.
Electrabel said on Thursday the Doel 4 reactor had shut automatically on Aug. 5 following an oil leak in its steam turbine in the non-nuclear part of the plant. The firm said the leak had caused major damage to the turbine’s high-pressure section.
“Based on this partial analysis, Doel 4 will certainly not be available before Dec. 31, 2014,” Electrabel said.
A GDF Suez spokesman confirmed Belgian press reports about suspicion of sabotage.
“There was an intentional manipulation,” he said, adding that somebody had tampered with the system used for emptying oil from the Alstom-made turbine.
He said no outsiders had penetrated into the plant but declined to say whether an employee could have purposely caused the leak, as has been reported in some Belgian media.
He said Electrabel had filed a complaint and that the Belgian police had started an investigation.http://uk.reuters.com/article/2014/08/14/belgium-nuclear-doel-idUKL6N0QK43R20140814

Fukushima: Bad and Getting Worse – Global Physicians Issue Scathing Critique of UN Report on Fukushima CounterPunch, by JOHN LaFORGE, 20 July 14 “……..Points of agreement: Fukushima is worse than reported and worsening still
Before detailing the multiple inaccuracies in the UNSCEAR report, the doctors list four major points of agreement. First, UNSCEAR improved on the World Health Organization’s health assessment of the disaster’s on-going radioactive contamination. UNSCEAR also professionally “rejects the use of a threshold for radiation effects of 100 mSv [millisieverts], used by the International Atomic Energy Agency in the past.” Like most health physicists, both groups agree that there is no radiation dose so small that it can’t cause negative health effects. There are exposures allowed by governments, but none of them are safe.
Second, the UN and the physicians agree that areas of Japan that were not evacuated were seriously contaminated with iodine-132, iodine-131 and tellurium-132, the worst reported instance being Iwaki City which had 52 times the annual absorbed dose to infants’ thyroid than from natural background radiation. UNSCEAR also admitted that “people all over Japan” were affected by radioactive fallout (not just in Fukushima Prefecture) through contact with airborne or ingested radioactive materials. And while the UNSCEAR acknowledged that “contaminated rice, beef, seafood, milk, milk powder, green tea, vegetables, fruits and tap water were found all over mainland Japan”, it neglected “estimating doses for Tokyo … which also received a significant fallout both on March 15 and 21, 2011.”
Third, UNSCEAR agrees that the nuclear industry’s and the government’s estimates of the total radioactive contamination of the Pacific Ocean are “far too low.” Still, the IPPNW reports shows, UNSCEAR’s use of totally unreliable assumptions results in a grossly understated final estimate. For example, the UN report ignores all radioactive discharges to the ocean after April 30, 2011, even though roughly 300 tons of highly contaminated water has been pouring into the Pacific every day for 3-and-1/2 years, about 346,500 tons in the first 38 months.
Fourth, the Fukushima catastrophe is understood by both groups as an ongoing disaster, not the singular event portrayed by industry and commercial media. UNSCEAR even warns that ongoing radioactive pollution of the Pacific “may warrant further follow-up of exposures in the coming years,” and “further releases could not be excluded in the future,” from forests and fields during rainy and typhoon seasons –when winds spread long-lived radioactive particles – a and from waste management plans that now include incineration.
As the global doctors say, in their unhappy agreement with UNSCAR, “In the long run, this may lead to an increase in internal exposure in the general population through radioactive isotopes from ground water supplies and the food chain.”……” http://www.counterpunch.org/2014/07/18/fukushima-bad-and-getting-worse/
Hot cooling canals threaten shutdown of Turkey Point nuclear power plants BY JENNY STALETOVICH JSTALETOVICH@MIAMIHERALD.COM 18 July 14, Rising water temperatures and severe algae blooms in cooling canals have threatened to force the shutdown of two nuclear reactors at Florida Power & Light’s Turkey Point plant over the last few weeks.
The utility and federal regulators say there isn’t a public safety risk but the canal temperatures, climbing to 94 to 99 degrees, have come within one degree of a federal limit that would mandate an expensive shutdown at a time when power demands are soaring. The hot water has also stoked the spread of algae through the 168-mile long canal system, which has helped keep temperatures high and reignited concerns about the power plant’s impact on water quality in Biscayne Bay………
Mining companies just west of Turkey Point have also argued that saltier water from the sprawling canal system, which is heavier than freshwater, has sunk deep within the aquifer and migrated west, threatening their business as well as drinking water wells.
“When they were originally conceived and designed in the late 60s and early 70s, they were supposed to theoretically operate in a way that the salinity in the canals was going to mimic what’s in the bay,” said Ed Swakon, president of EAS Engineering and a consultant for Atlantic Civil, which operates a large mine just west of the canals. But over the years, salt built up, he said, making the water heavier and forcing it deeper underground.
At some 70 feet below the surface, he said, “it begins to spread like an inverted mushroom.”………
on Wednesday, Scott Burns, a chief environmental scientist with the water management district, said tests conducted in recent years indicate underground water is creeping west. And in a letter last month, Justin Green, chief of DEP’s office that permits power plants, said FPL has been “put on notice” about the creeping plume. DEP and the water management district, he said, are drafting an order to deal with it, which will include pumping water from the Floridan Aquifer, deep below the Biscayne.
“When we increase pumping, that will reduce salt seepage and stabilize the system,” Burns said.
But Phil Stoddard, mayor of South Miami and a longtime critic of Turkey Point’s nuclear operations, worries drawing more water from the lower aquifer will make things worse.
“All the crap we’ve thrown into the Floridan is going to end up in the Biscayne Aquifer heading toward the drinking water,” he said. “The green slime is absorbing heat and heating up the water. The problem for FPL is hot water doesn’t do such a good job of cooling the pipes.” http://www.miamiherald.com/2014/07/16/4239899/hot-weather-threatens-cooling.html
