France’s Nuclear Nightmare Deepening

Posted by feww on October 17, 2017

29 EDF nuclear reactors risk complete or partial loss of cooling systems –ASN

The French Nuclear Safety Authority (ASN) has issued an INES level 2 alert (scale of 0-7) due to the risk of loss of cooling systems for 20 of the reactors “of concern” operated by EDF.

The 29 reactors, with capacities ranging from 900 – 1300 MWe, are located at 12 nuclear power plants in the Belleville-sur-Loire, Cattenom, Chinon, Cruas, Dampierre-en-Burly, Golfech, Nogent-sur-Seine, Paluel, Saint-Alban and Saint-Laurent-des-Eaux NPPs, ASN reported.

The reactor heat sink could be lost owing to the unavailability of the pumps of the reactor essential service water system (SEC) as a result of internal flooding following an earthquake-induced rupture of the piping supplying water to the fire protection network (JPP system) and the raw water filtration network (SFI or CFI systems).

Vulnerability to Earthquakes

“The insufficient earthquake resistance of a JPP pipe was initially detected by EDF in the Belleville-sur-Loire NPP. Additional investigations requested by ASN and performed by EDF in early June 2017 revealed that several sections of these pipes were degraded, with thicknesses less than the minimum thickness required for earthquake resistance. This degradation is the result of corrosion which may have developed because of a lack of appropriate preventive maintenance. This event was provisionally rated level 1 on the INES scale on 2nd August 2017,” ASN reported.

Risk of Total Loss of Heat Sink

“EDF then took thickness measurements on piping sections of other systems (SFI and CFI) situated in the same areas as the JPP pipes, from early July to the end of September 2017, on all the EDF NPP reactors potentially concerned. Following this measurement campaign and then the earthquake resistance analysis of the piping concerned, EDF declared on 10th October 2017 that 20 reactors were concerned by a risk of total loss of heat sink (loss of both trains of the SEC system). This event is therefore rated level 2 on the INES…”

20 Reactors Subject to the INES Level 2 Alert (“Incident”)

  • Belleville-sur-Loire NPP: reactors 1 and 2
  • Cattenom NPP: reactors 1, 2, 3 and 4
  • Chinon NPP: reactors B3 and B4
  • Cruas NPP: reactors 1 and 4
  • Dampierre-en Burly NPP: reactors 1, 2, 3 and 4
  • Golfech NPP: reactors 1 and 2
  • Nogent-sur-Seine NPP: reactors 1 and 2
  • Saint-Laurent-des-Eaux NPP: reactors B1 and B2

9 Reactors subject to the INES Level 0 Alert (“Deviation”)

  • Cruas NPP: reactors 2 and 3
  • Paluel NPP: reactors 3 and 4
  • Saint-Alban NPP: reactors 1 and 2
  • Tricastin NPP: reactors 1, 3 and 4

EDF

Électricité de France (EDF) is the country’s main electricity generation and distribution company, managing 58 reactors. French Government owns about 85% of EDF shares.

Nuclear power forms 40% of France’s energy consumption, and is the largest source of electricity generation in the country, accounting for more than 76% of the total production of 546 TWh in 2015, the highest percentage in the world.

FLOODING AT TWO NEBRASKA NUCLEAR POWER PLANTS

Posted by feww on June 23, 2011

Floodwaters rising at Cooper and Fort Calhoun nuclear power plants, Nebraska

The U.S. Nuclear Regulatory Commission (NRC) said in a statement that is was closely watching conditions along the Missouri River where floodwaters are rising at two Nebraska nuclear power plants, the Cooper Nuclear Station and the Fort Calhoun NPP.

The lowest of four levels of emergency notification remain in effects at both plants, NRC said.

“We are closely following events at both plants,” NRC Region IV Administrator Elmo Collins said. “Both plants have activated their flood response plans and taken appropriate steps to protect vital structures, systems and components from rising floodwaters and maintain their plants in a safe condition.”

Cooper NPP, located in Brownville, Nebraska, is currently about 70 cm (two and a half feet) above current river levels, and is operating at full power. However, it remains under the ‘Unusual Event’ declared on June 19, NRC said.

Fort Calhoun, which is about 30 km (19 miles) north of Omaha, was shut down for refueling on April 7 and has not since been restarted. It remains under the Unusual Event declared on June 6.

“The NRC has augmented its inspection staff at Fort Calhoun where there is now two feet of water in many areas onsite,” the report said.

Flooding along the Missouri River to continue until mid-August

Water release from the reservoirs and dams along the Missouri River is expected to continue until at least mid-August, resulting “in near-record flooding along portions of the Missouri River.”

Earlier the NWS released the following statement:

“The upper Missouri River Basin (Montana, Wyoming, North and South Dakota and Nebraska) has received 100 to 800 percent of normal precipitation during the past several weeks. Snow pack runoff entering the upper portion of the river system is more than twice the normal amount.

“These conditions have resulted in Missouri basin reservoirs across eastern Montana and the Dakotas nearing their maximum levels. Reservoir water release rates are expected to stay at high release levels (150,000 cfs) into August. These extremely high flows, combined with normal rainfall, will result in near-record flooding along portions of the Missouri River.”


The graphic above shows where recent river gauge forecasts are available, and are colored according to their values.  They are the most recent guidance forecasts we have issued as of the date/time stamp on the bottom of the graphic.  Orange, magenta, and red dots represent river points that are forecast to be in flood.  Yellow dots represent those which are under flood stage, but are high enough to merit some internal action (e.g., perhaps a crest forecast is issued, or a forecast is issued more frequently).  Green dots represent stages that are below the action stage and are not high enough to merit much hydrologic concern.  Gray dots mean that the status couldn’t be determined (perhaps because no forecasts for these points have been recently issued).

Storm Xynthia Kills at least 60 in Europe

Posted by feww on March 1, 2010

At least 60 people have been killed in Europe as storm Xynthia buffet the west coasts of Spain, Portugal and France.

About fifty of the victims were killed in France, most of whom were drowned, while others were hit by falling trees or collapsing buildings, as 140km/h winds pummeled the coastal towns in the three countries, causing widespread flooding, destroying buildings and cutting power to nearly 2 million homes.

French Nuke Waste Plagues Siberia

Posted by feww on October 12, 2009

EDF nuclear waste dumped in open air in Siberia, Russia

Why i s it that everything that comes out of France lately turns out to be toxic?

Radioactive waste from France’s power group EDF are being dumped in the open air in Russia, French newspaper Liberation reported.

Some 13 percent of radioactive waste produced by France’s power giant is dumped in a town in Siberia, Liberation said, adding that its information was based on an investigative report, which would be broadcast on French TV channel ARTE  on Tuesday night local time.

“An EDF spokeswoman declined to confirm the 13 percent figure, or that waste was stored in the open air, but confirmed EDF sends nuclear waste to Russia.” Reuters reported.

“We send waste to Russia for treatment, and they send 10 to 20 percent of it back to us to be used in French power plants,” she was reported as saying.

The world’s largest nuclear power producer, EDF is about 85 percent state-owned, operating 58 reactors in 19 nuclear plants in France.

This’s Got to Be the Year of Radioactive, Chemical and Oil Spills, Too!

Posted by terres on July 24, 2008

The Moderators have so far declared 2008 the year of fire, tornadoes and volcanic eruptions.

We were wondering whether 2008 could also be declared the year of radioactive, chemical and oil spills, too, almost certain of the knowledge that Areva, EDF and the likes would not “disappoint” us!

French Nuke Industry, Again!

Sure enough, in the third incident of uranium spillage in two weeks, it was revealed that about 100 employees at a nuclear power plant in southern France were contaminated with radiation during maintenance work at the Tricastin reactor number four.

Nuke Leaks, USA: Contaminated US site faces ‘catastrophic’ nuclear leak

More than 210 million liters of radioactive and chemical waste are stored in 177 underground tanks at Hanford in Washington State. Most are over 50 years old. Already 67 of the tanks have failed, leaking almost 4 million litres of waste into the ground. New Scientist reported.

Mississippi Oil Spill [Though Not the Largest Ever!]

Meanwhile, back home, A chemical tanker broke a fuel barge in half on the Mississippi River. About 420,000 gallons (1,589,700 liters) of fuel oil No. 6 [described as lighter than crude oil, but heavier than diesel] were spilled forcing the closure of a 58-mile (93km) stretch from New Orleans southward.

“It’s not the largest spill we’ve ever had, but it’s a large one,” said Louisiana Department of Environmental Quality spokesman Rodney Mallett. [Well, isn’t that a relief!]

Vanadium mine leak in China

Sludge from a vanadium mine in northwestern China contaminated two nearby rivers, Shuanghe River and Donghe River in Shaanxi province, when a spillway collapsed on Tuesday and sent authorities scrambling to protect drinking water supplies, Xinhua news agency said.

“The black-colored waste water with a layer of white bubbles on the top is being stopped by multiple (makeshift dams) and stored and diverted to low-laying areas,” Xinhua said.

“In April, ore tailings from another vanadium mine in Shanyang county polluted and literally blackened three rivers, state media reported at the time.” Reuters reported.

[All vanadium compounds should be considered highly toxic. Generally, the higher the oxidation state of vanadium, the more toxic the compound is. The most dangerous compound is vanadium pentoxide.]

Oil Spill in Amur River

Russia informed China of oil pollution in the Amur River On July 8. last week, the Ministry of Environmental Protection ruled out the possibility that the fuel oil pollution in Amur, or Heilongjiang River, was China.

Mystery oil spill in Patagonia: January 2008 [Don’t you just love the murder mystery spin?]

“The overall spill is made up of several slicks, two to three kilometers wide along a total extension of approximately forty kilometers,” reported the local newspaper El Chubut.

“Argentine government is analyzing recent satellite imagery to determine the cause of the spill but has yet to determine where the oil came from. According to local media reports, several corporations are suspected of causing the spill.” IFAW reported.

Black Sea and San Francisco Bay Oil Spills: Environmental disasters follow oil spills

“In the Black Sea and San Francisco Bay, tens of thousands of birds, countless marine creatures and a half-dozen people died following oil spills. The spills in the Black Sea were caused by ships running aground and sinking during the worst storm the region has seen in decades, while the spill in the Bay Area was caused by a lone container ship hitting a bridge in fog. Environmental groups working in both regions call the spills ecological catastrophes.” GEOTIMES wrote.

In Russia, a severe storm struck the Black Sea on Nov 11 damaging or sinking 11 ships and tankers. a total of about 1 million gallons (1,378,500 liters ) of oil was spilled into the Kerch Strait, which ends in the Black Sea, killing as many as 15,000 birds. It’s thought as many as 11 endangered species of birds inhabit the area, and many more migrate through the fragile eco-region.

A container ship in San Francisco Bay struck the Bay Bridge on Nov. 7, causing substantial damage to the vessel and spilling about 60,000 gallons (~ 227,00 liters) of fuel oil into the bay. Some 2,500 birds died as a result. Experts say the region may be affected by the spill for the next 20 years.

Although the two incidents happened in November 2007, the full environmental impacts are now beginning to appear.

Norwegian oil spill raises concern about future oil plans

The second biggest oil spill in Norway occurred in December 2007, reviving concerns of the possible expansion of oil and gas exploration in Norwegian waters.

The spill of around 25,000 barrels left an oil slick 5 kilometres wide and 10 kilometres long. Fortunately the accident was mostly contained by favourable winds. The accident occurred as a tanker was loaded at energy group StatoilHydro’s Statfjord field. IceNews reported.

Norway Again: Oil spill on Draugen

The Petroleum Safety Authority Norway (PSA) has conducted an investigation of the incident that occurred on Draugen on 10 January 2008, which led to an oil spill of about 6 m3 to the sea. On the basis of our findings we have issued an order to A/S Norske Shell (Shell) and Teekay Shipping Norway AS (Teekay). The Petroleum Safety Authority Norway reported.

Oh, NO! Not Norway Again!

During oil offloading from the Statfjord A platform in the North Sea, about 4,000 cubic meters (~ 1.1 million gallons) of crude oil was spilled into the sea on the December 12 causing marine pollution. The Statfjord field is located around 200 kilometres west of Bergen, close to the border of the UK continental shelf. Statfjord was discovered by Mobil in 1974, and Statoil took over the operatorship on 01 January 1987. The field is likely to remain in production until 2019. MarineBuzz reported.

Oil Spill Lebanon

“war on Lebanon brought about the biggest environmental catastrophe in the history of this small country. 15,000 tons of oil spilled from Jiyyeh power [plant] after Israeli bombardment spilling oil onto most of the Lebanese coast. ”

“A lot of oil is still on the beach, but all oil spill cleanup operations have stopped due to lack of funding. The last organization doing cleanup is ‘Bahr Loubnan’ NGO that was cleaning rocks from oil near Jiyeh using high pressure water jets. A lot of oil can still be found on shore all along the coast in Jiyeh, Beirut, Tabarja, Jbeil and Anfeh. The Ministry of Environment has issued a call for the second phase of cleanup and is looking for funding.” Oil Spill Lebanon reported.

Oil Spill Korean Style

In South Korea’s worst oil spill [December 2007,] a crane barge punched holes into Hebei Spirit tanker which spewed 10,500 tons (3.4 million gallons) of its crude oil load into the sea.

Folks, it’s time to drill the Arctics some more. There’s too much pollution out here!
