Fukushima nuclear reactor clean-up unit hit by acid leak http://www.theaustralian.com.au/news/world/fukushima-nuclear-reactor-cleanup-unit-hit-by-acid-leak/story-e6frg6so-1226772520045 STAFF WRITERS AFP DECEMBER 02, 2013 THE trouble-prone system used to decontaminate radioactive water at Japan’s crippled Fukushima nuclear power plant was switched off yesterday because of a chemical leak, the plant’s operator said.
Hydrochloric acid, used to neutralise the alkaline water being decontaminated, was found seeping from a pipe joint, the Tokyo Electric Power Co said.
The joint was wrapped in a vinyl bag to contain the leakage, TEPCO said, and the company was investigating the cause. About a litre of hydrochloric acid had been contained in the bag. The leak was found at one of three Advanced Liquid Processing System units designed to remove radioactivity from contaminated water at the plant, where a massive earthquake and tsunami in March 2011 sent the nuclear reactors into meltdown.
The systems are expected to play a crucial role in treating the huge amounts of toxic water accumulating at the plant. The troubled system was one of two units that had been in trial operation and were due to go into full operation yesterday.
In late September, plastic padding clogged up a drain in the same system, causing it to shut down. In October, it was halted due to a programming mistake.
Thousands of tonnes of water, used since the meltdown to cool reactors or polluted by other radioactive material, are being stored in huge tanks at the site on Japan’s northeast coast.
Nuclear Regulatory Commission employees surf porn while on the job, December 01, 2013 by: J. D. Heyes (NaturalNews) It’s something that Homer Simpson would most likely do, but he’s a cartoon character and isn’t even real. Still, it is an apt comparison given Simpson’s cartoon job status as an employee at a nuclear power plant.
As reported by The Washington Times, employees at the Nuclear Regulatory Commission, the federal agency that oversees the operations of the nation’s nuclear power plants, recently managed to bypass government firewalls and access porn online with their work computers.
From the paper:
It’s become tougher to surf porn on government computers after scandals, but some workers at the Nuclear Regulatory Commission managed to find ways to bypass detection software and firewalls to get the illicit content, records show.
One contract employee watched, in his words, two “porn type” Netflix movies during “downtime” on his 12-hour shift at the commission’s office of information services, according to case records reviewed by The Washington Times.
Problem has not gone away
Another employee, the paper said, had repeatedly used photo-sharing website Flickr to search for porn while in the office.
And for years, a resident inspector at the nuclear agency scanned eBay looking for images of porn.
Bomb explodes near Indian nuclear reactor,THE AUSTRALIAN, ROBIN PAGNAMENTA THE TIMES NOVEMBER 29, 2013 A BOMB has exploded close to India’s biggest nuclear power station, killing six people and prompting a police investigation into whether it was linked with anti-nuclear protests in the area. The device exploded in a village close to Kudankulam in the southern state of Tamil Nadu, destroying at least two houses and seriously injuring three people. Among the six killed were a woman and three young children.
Vijayendra Bidari, a police spokesman, said the house in which it exploded was being used as a “bomb-making facility” in a village where anti-nuclear activists had been operating. He said the bomb apparently detonated accidentally as the suspected activists were building it. Two unexploded bombs were recovered from the site. The blast occurred about 1km from the Russian-built plant, which started operating last month – six years later than was planned – despite protests from locals who fear a nuclear accident.
Kudankulam lies in a seismically active area and the coastal zone was affected by the 2004 tsunami. Activists fear there could be a repeat of the 2011 Fukushima nuclear disaster in Japan.
SP Udayakumar, the founder of the People’s Movement Against Nuclear Energy, the main anti-nuclear group in the region, denied involvement in the bomb-making. “We made it clear immediately that we have nothing to do with the bomb blasts,” he said.
- Mr Udayakumar said he believed gangs associated with illegal mining were behind the blasts. – ………:
S.Korea nuclear reactor hit by automatic shutdown; six units now off First Post World, 29 Nov 13, SEOUL (Reuters) – A “safety-related action” automatically shut down one of its 23 nuclear reactors on Thursday, South Korea’s nuclear operator said, bringing the tally of those closed to six and hiking chances of possible power blackouts this winter……. “We are now looking into the cause of the shutdown and it is not yet clear when the reactor will restart,” said a spokesman at operator Korea Hydro & Nuclear Power. Operation of the 587-megawatt Kori No. 1 reactor, over 300 km southeast of Seoul, was suspended early on Thursday morning. The reactor, which started operation in 1978, had recently returned from nearly 180 days of scheduled maintenance through October 5, according to KHNP’s website. (www.khnp.co.kr). The unit’s license to operate was extended another 10 years in end-2007, another KHNP spokesman noted……
Iran Earthquake Near Nuclear Plant Kills ‘Seven’ http://news.sky.com/story/1175142/iran-earthquake-near-nuclear-plant-kills-seven 28 Nov 13 The epicentre lies 35 miles from the Bushehr nuclear plant, where concerns have been expressed in the past about possible leaks A 5.7-magnitude earthquake near an Iranian nuclear plant has killed seven people and injured 30, according to reports.
The quake’s epicentre was near Borazjan, around 60km (35 miles) from Bushehr, where Iran has its Russian-built reactor.
Emergency Response Chief Hassan Qadami told IRNA news agency: “So far, there are seven dead and 30 injured receiving hospital treatment.” Iran stands on several seismic fault lines. A massive quake in December 2003 struck the southern city of Bam, killing 26,000 people and destroying its ancient mud-built citadel.
Iran’s Arab neighbours across the Gulf have often raised concern over the reliability of the Bushehr plant and the risks of radioactive leaks in case of a major quake.
But Iran and Russia insist it respects international standards under the supervision of the UN nuclear watchdog.
Explosion at Idinthakarai claims 6 lives, THE HINDU P. SUDHAKAR 26 NOV 13, Six persons, including two children and a woman, were killed and a few others injured seriously on Tuesday evening when country bombs exploded in a house at Tsunami Colony at Idinthakarai, the epicentre of protests against the Kudankulam Nuclear Power Project.
Police fear the toll could rise as people might have been trapped under debris.
One presumption is that that the country bombs exploded when the miscreants were engaged in making a bomb in the house. Police suspect the explosion could be because of rivalry between two groups who hail from Kooththenkuzhi, about 6 km from Idinthakarai…….http://www.thehindu.com/news/national/tamil-nadu/5-killed-in-blast-at-hub-of-antikudankulam-protests/article5394541.ece
Pipeline blamed for spill at former uranium plant in Colorado http://trib.com/business/energy/pipeline-blamed-for-spill-at-former-uranium-plant-in-colorado/article_de1c924f-92ae-5df5-b0d8-e5be8d2282da.html By the Associated Press, 25 Nov 13, CANON CITY, Colo. — A pipeline rupture led to a spill of an estimated 4,000 to 9,000 gallons of contaminated water spilled at a former uranium mill near Canon City, but an on-site collection system contained the spill, officials told residents.
A joint on the underground pipeline broke Nov. 5, unleashing the spill at the defunct Cotter Corp. mill, Jennifer Opila, a radioactive materials monitor for the state health department, told the Thursday meeting. The pipe was repaired and operable by Nov. 6, Opila said.
Cotter safety officer Jim Cain said between 4,000 and 9,000 gallons of water spilled. A sample showed traces of uranium and molybdenum were found, Cain said.
John Hamrick, vice president of Cotter Mill operations, said there have been three leaks “in three different years, all for different reasons.”
Cotter once processed uranium for weapons and fuel at the mill. Federal authorities placed the mill on a national list for Superfund cleanups in the 1980s after radioactive materials traced to the mill were found to have contaminated the soil and groundwater. Part of the neighboring Lincoln Park community also is a Superfund site.
The U.S. Environmental Protection Agency eventually turned oversight of cleanup work to state officials.
Uranium hasn’t been processed at the mill since 2006. The state requires mill sites that are being decommissioned to be thoroughly cleaned up and restored at the operator’s expense. It’s expected to be a multimillion-dollar effort.
Seaweed shuts down Scottish nuclear reactor Seawater cooling system of Torness in East Lothian has become clogged with seaweed for the second time this year Rob Edwards theguardian.com, Friday 22 November 2013 A nuclear reactor near Edinburgh shut down on Thursday because its seawater cooling system became clogged with seaweed.

Durban uranium stash sparks nuclear alert 2013-11-19 Rowan Philip and Jonathan Erasmus, The Witness Durban – A shopping bag filled with stolen uranium has been seized in a sting operation in Durban, triggering alarm among local and international nuclear watchdog agencies.
The kilogram of the radioactive material confiscated is believed to be a mere sample from a much larger batch, for which police are now hunting.
In a joint operation involving the Durban organised crime unit, crime intelligence and the department of minerals and energy, two men were arrested in their car opposite a shopping centre on the Bluff, following an informant’s tip-off…..
Defunct Cañon City uranium mill discharges tainted water The Gazette, The Associated Press November 13, 2013 CANON CITY — A ruptured underground pipe discharged contaminated water from the defunct Cotter Corp. uranium mill near Cañon City.
The Denver Post reports that the contaminated water spill is the third in the last four years (http://bit.ly/HLG5jd).
The spill was reported Nov. 5. It was five to 10 times larger than previous discharges.
The Colorado Department of Public Health and Environment says the company reported 4,000 to 9,000 gallons of water tainted with uranium and molybdenum spilled onto the ground…… http://gazette.com/defunct-caon-city-uranium-mill-discharges-tainted-water/article/1509264
1 reactor shut down at Oconee Nuclear Station The Tribune, : October 25, 2013 By JEFFREY COLLINS — Associated Press COLUMBIA, S.C. — The Oconee Nuclear Station near Seneca had to shut down one of its three reactors after a problem in the water system that helps generate electricity, federal regulators said.
Unit 3 at the plant was manually shut down by Duke Energy around 6 a.m. Thursday, about four minutes after the problem was detected, Nuclear Regulatory Commission spokesman Roger Hannah said.
A control valve in the plant’s water system started causing changes in the flow of water that generates steam to turn the turbines and create power. Engineers shut down the reactor before it was automatically turned off, and there was no danger to the public, Hannah said……. The shutdown did come in the same month the Government Accountability Office released a report about nuclear plant safety. Since 2000, the Oconee Nuclear Station reported the most safety violations of any nuclear plant in the Southeast.
The plant reported 163 lower-level violations and 14 higher-level violations. Lower-level violations pose very low risk, such as improper upkeep of a transformer, while higher-level violations range in significance, such as an electrical system that caused a fire…….. The Browns Ferry plant in Decatur, Ala., reported 135 lower-level violations and six higher-level violations, while the Palo Verde plant in Wintersburg, Ariz., reported 299 lower-level violations and five higher-level violations since 2000. http://www.sanluisobispo.com/2013/10/25/2749832/1-reactor-shut-down-at-oconee.html
[Photo] 2 holes found in the bottom of 300m3 leakage tank / Entirely deteriorated http://fukushima-diary.com/2013/10/photo-2-holes-found-in-the-bottom-of-300m3-leakage-tank-entirely-deteriorated/ by Mochizuki on October 8th, 2013
Tepco has been dismantling the tank since yesterday that experienced the 300m3 of leakage. The structural flaw may cause other tanks of the same type to leak commonly. Tepco is investigating the potential leaking points.
From their inspection, they found 2 holes around the bolt parts, which are 3mm × 11mm and 3mm × 22mm.
The flange parts were rusting inside and outside. The bottom parts of the tank were found severely deteriorated.

Iran foils nuclear plant sabotage plot http://www.skynews.com.au/world/article.aspx?id=912635 Sunday October 6, 2013 Iran has arrested four people suspected of attempting to sabotage one of its nuclear plants, Atomic Energy Organisation chief Ali Akbar Salehi says. ‘Some time ago, we uncovered sabotage activities by several people at a nuclear plant,’ Salehi said in comments carried by the Mehr news agency on Sunday.
‘We let them continue their activities so that we could gather more intelligence. ’We arrested them at the appropriate moment and their interrogation is ongoing.’ Salehi did not specify which of Iran’s nuclear plants was targeted.
In August last year, saboteurs blew up power lines supplying Iran’s underground uranium enrichment plant at Fardo outside the central city of Qom.
In 2010, a US cyber-attack, reportedly carried out in collaboration with Israel, hit Iran’s nuclear facilities. The Stuxnet virus was tailored specifically to target uranium enrichment facilities. ’There are still viruses out there but we have taken the necessary measures,’ Salehi said.
‘Since we uncovered the Stuxnet virus, we have reinforced our protection systems and a special unit has been set up.’ In recent years, Iran has detained a number of alleged US or Israeli agents accused of spying on, or attempting to sabotage, its nuclear program. Several Iranian nuclear engineers have also been killed in what Tehran says were assassinations by foreign intelligence services.
