Florida Nuclear Station is leaking radioactive material into Biscayne Bay

Radioactive ‘tracer’ detected at up to 215 normal levels near canals

County commission set to discuss cooling canal problems Tuesday

Threat from pollution to public, marine life not addressed in report

Recent sampling of water in Biscayne Bay found higher than normal levels of tritium, a rare hydrogen isotope produced by nuclear reactors and used to track water leaking from Turkey Point’s cooling canals. Tim Chapman Miami Herald Staff MIAMI HERALD BY JENNY STALETOVICH  jstaletovich@miamiherald.com    http://www.miamiherald.com/news/local/environment/article64667452.html#storylink=cpy

A radioactive isotope linked to water from power plant cooling canals has been found in high levels in Biscayne Bay, confirming suspicions that Turkey Point’s aging canals are leaking into the nearby national park.

According to a study released Monday by Miami-Dade County Mayor Carlos Gimenez, water sampling in December and January found tritium levels up to 215 times higher than normal in ocean water. The report doesn’t address risks to the public or marine life but tritium is typically monitored as a “tracer” of nuclear power plant leaks or spills.

The study comes two weeks after a Tallahassee judge ordered the utility and the state to clean up the nuclear plant’s cooling canals after concluding that they had caused a massive underground saltwater plume to migrate west, threatening a wellfield that supplies drinking water to the Florida Keys. The judge also found the state failed to address the pollution by crafting a faulty management plan.

This latest test, critics say, raise new questions about what they’ve long suspected: That canals that began running too hot and salty the summer after FPL overhauled two reactors to produce more power could also be polluting the bay………

Over the last two years, problems with the canals have worsened exponentially. After the 2013 plant expansion to increase power output by 15 percent, the canals began running dangerously high. FPL officials blamed problems on an algae bloom that worsened after the canals were temporarily shut down during the project. But when a summer drought hit in 2014, temperatures spiked. At least twice, when temperatures soared to 102 degrees, the utility was nearly forced to power down reactors.

After obtaining permission from nuclear regulators to operate the canals at 104 degrees, the hottest in the nation, FPL officials began plotting a course to fix the canals by pumping in millions of gallons of fresh water from a nearby canal as well as increasing the amount of water drawn from the Floridan aquifer.

But the growing saltwater plume triggered regulatory scrutiny. After the county complained, the state ordered a new management plan, called an administrative order, to address problems……..

Over the last five years, the report said, cooling canal water typically has tritium at levels 60 to more than 800 times higher than in the bay. Tritium at the bottom of the bay close to the canals ranged from more than 130 to 215 times higher — high enough to suggest a consistent flow from the sprawling cooling system.

County staff concluded the findings are “the most compelling evidence” that canal water has spread into the bay.

Deep seated concern about Canada’s nuclear safety

safety-symbol-Smflag-canadaCan the Canadian Nuclear Safety Commission do better?  http://www.waterkeeper.ca/blog/2016/3/2/can-the-canadian-nuclear-safety-commission-do-better by Mark Mattson.

If your drinking water comes from Lake Ontario, then you’re one of the millions of people who count on the Canadian Nuclear Safety Committee to do its job perfectly. The same is true for other Canadians who work in the nuclear industry or live near a facility.

In an interconnected, hi-tech world, we rely on regulatory agencies to keep us safe. We assume that buildings are well constructed, that toxic products will be banned, that the water coming out of our faucets will be safe to drink – and if any of these things doesn’t happen, we assume we will be warned.

When we are wrong, the consequences can be grave. Think of the Walkerton tragedy or the crisis in Flint.

Of course, the consequences of poor regulation aren’t always obvious. They may be difficult to detect or very distant from the root cause. Imagine low levels of a carcinogen (say PFOA) in a town’s drinking water, for example. If the regulator fails to prevent this, it is unlikely that the residents will detect its presence. Even if rare cancers begin to appear, making the connection can be difficult.

The CNSC is responsible for protecting Canadians from the risks associated with the nuclear industry. This means ensuring that Canada never has to deal with the pandora’s box of problems that would stem from a complete or partial meltdown, or major release of radioactive material into the environment. It means protecting Canadians from those insidious, day-to-day harms that are harder to detect, like low level radiation or the slow release of radionuclides into the watershed. It also means protecting Canadians from the impact of non-nuclear contaminants, habitat loss, and environmental destruction.

If you’ve followed some of our previous work, you’ll know that Waterkeeper questions whether the CNSC effectively serves the public as an impartial regulator. We believe the CNSC relies on an inadequate licensing process, demonstrates limited appreciation of environmental risks, and has a tendency to downplay or ignore concerns raised by the public.

When regulatory agencies show signs of failing to meet their public duties, it’s important to speak up. In fact, any individual or organization that has such concerns has an obligation to share them. After all, you rely on us to help keep you safe, too.

For this reason, Lake Ontario Waterkeeper is joining Greenpeace Canada, Ecojustice, the Canadian Environmental Law Association and others in calling on Prime Minister Trudeau to initiate a twenty year review of the Nuclear Safety and Control Act. This is the legislation that dictates how the CNSC operates. 

Reviewing the Act would provide an opportunity to address deep-seated concerns about the CNSC and improve nuclear regulation in Canada. You can read the open letter that has been sent to Prime Minister Trudeau below. (on original)

Trudea called upon to fix Canada’s nuclear law and oversight

safety-symbol-Smflag-canadaGroups urge Trudeau to fix Canada’s nuclear law and oversight, National Observer By Mike De Souza  March 8th 2016 Canada needs to fix its nuclear safety law and put a stop to internal political strategizing by its industry watchdog that is putting public safety at risk, Prime Minister Justin Trudeau was told in an open letter released on Tuesday.

 Fourteen groups, led by Greenpeace Canada, wrote in the letter that Trudeau should use the upcoming fifth anniversary of the Japanese Fukushima disaster to launch a full parliamentary review of the law, the Nuclear Safety and Control Act.

The groups released the letter along with a federal strategy document showing that staff at the watchdog were recommending that management consider the “political environment” in 2015 prior to developing any changes needed to improve nuclear oversight.

Greenpeace Canada said this indicates there was political strategizing by the watchdog, theCanadian Safety Nuclear Commission, and demonstrates why the Liberal government has to clean up Canadian nuclear oversight………

All 14 groups, including MiningWatch Canada, EcoJustice and the Canadian Environmental Law Association, said that Japan and the European Union have increased the independence and transparency of their nuclear watchdogs in the wake of the disaster. But the groups argued that the previous federal government, led by former prime minister Stephen Harper, failed to keep pace with the other jurisdictions to prepare the country for any similar disaster in Canada.

“While the (Canadian watchdog) carried out a review of the technical failures that led to radioactive releases at Fukushima, it did not consider how institutional failures and industry-led regulation caused the accident,” said the letter to Trudeau. “This should be addressed as part of a public review process leading to the modernization of the (law).”…..

Greenpeace Canada nuclear analyst Shawn-Patrick Stensil said Trudeau needs to put a stop to the commission’s internal strategizing.

“In public the CNSC says Canada’s nuclear safety laws are fine, but behind closed doors they’re strategizing on how to amend the law without public input,” Stensil told National Observer. “If they’re not being honest with the public about things like this what else are they trying to hide? This is why Trudeau should clean house at the CNSC.”……..http://www.nationalobserver.com/2016/03/08/news/groups-urge-trudeau-fix-canadas-nuclear-law-and-oversight

Japan’s Nuclear Regulator urges vigilance, has doubts on efficacy of underground ice wall around Fukushima

Japan’s nuclear watchdog chief urges safety vigilance by government, utilities, Japan Times, KYODO MAR 8, 2016  The head of the Nuclear Regulation Authority is urging the government and utilities to redouble their vigilance to ensure reactor safety, warning them not to drop their guard simply because units have cleared the NRA’s tough safety screening.

NRA Chairman Shunichi Tanaka, chairman of the Nuclear Regulation Authority, said passing the screening is “not enough” during an interview Monday ahead of Friday’s fifth anniversary of the Fukushima No. 1 disaster……..

The NRA chairman said the situation at Fukushima No. 1 is calm, with cleanup work making steady progress.

But he expressed doubts about the efficacy of an underground ice wall that Tepco has built around reactor buildings to prevent groundwater from flowing into their basements.

The wall “will not essentially help reduce the risk” of an increase in toxic water, he said……http://www.japantimes.co.jp/news/2016/03/08/national/japans-nuclear-watchdog-chief-urges-safety-vigilance-government-utilities/#.Vt80nX197Gh

Tokyo came close to nuclear catastrophe – former Japan PM Kan

n-kan-a-20160129-870x621Fukushima: Tokyo was on the brink of nuclear catastrophe, admits former prime minister, Telegraph UK, 6 Mar 16  Five years on from the tsunami, the former Japanese prime minister says the country came within a “paper-thin margin” of a nuclear disaster By , Tokyo Japan’s prime minister at the time of the 2011 earthquake and tsunami has revealed that the country came within a “paper-thin margin” of a nuclear disaster requiring the evacuation of 50 million people.

In an interview with The Telegraph to mark the fifth anniversary of the tragedy, Naoto Kan described the panic and disarray at the highest levels of the Japanese government as it fought to control multiple meltdowns at thecrippled Fukushima Daiichi nuclear power station.

He said he considered evacuating the capital, Tokyo, along with all other areas within 160 miles of the plant, and declaring martial law. “The future existence of Japan as a whole was at stake,” he said. “Something on that scale, an evacuation of 50 million, it would have been like a losing a huge war.”

Mr Kan admitted he was frightened and said he got “no clear information” out of Tepco, the plant’s operator. He was “very shocked” by the performance of Nobuaki Terasaka, his own government’s key nuclear safety adviser. “We questioned him and he was unable to give clear responses,” he said.

“We asked him – do you know anything about nuclear issues? And he said no, I majored in economics.”

Mr Terasaka, the director of the Nuclear and Industrial Safety Agency, was later sacked. Another member of Mr Kan’s crisis working group, the then Tepco chairman, Tsunehisa Katsumata, was last week indicted on charges of criminal negligence for his role in the disaster……….

Dramatic CCTV footage from the plant, released in 2012, showed a skeleton staff – the so-called “Fukushima 50” – struggling to read emergency manuals by torchlight and battling with contradictory, confusing instructions from their superiors at Tepco. At one stage, an appeal went out for workers to bring batteries from their cars so they could be hooked up to provide power for the crippled cooling systems.

Total disaster was averted when seawater was pumped into the reactors, but the plant manager, Masao Yoshida, later said he considered committing hara-kiri, ritual suicide, in despair at the situation…….

[Mr Kan] – “I knew that even based on what little we were hearing, there was a real possibility this could be bigger than Chernobyl. That was a terrible disaster, but there was only one reactor there. There were six here.”

Although the Fukushima disaster caused no immediate deaths from radiation, it did force the evacuation of almost 400,000 people, most of whom have still been unable to return to their homes. Hundreds of thousands more fled in panic and much of Fukushima province ceased functioning.

An area within 20km (12.5 miles) of the plant remains an exclusion zone, with no-one allowed to live there. Some studies have identified a higher incidence of child cancer in the wider region.

Mr Kan said that the nuclear accident is “still going on” today. He said: “In reactors 2 and 3, the radioactive fuel rods are still there and small amounts of [radioactive] water are leaking out of the reactor every day, despite what Tepco says.”

He said the experience had turned him from a supporter of nuclear power into a convinced opponent. “I have changed my views 180 degrees. You have to look at the balance between the risks and the benefits,” he said. “One reactor meltdown could destroy the whole plant and, however unlikely, that is too great a risk.”……..

He criticised his successor as prime minister, Shinzo Abe, for restarting some of the country’s nuclear power stations, all of which were shut down after the crisis, saying that Japan had “not learned the lessons enough” and was “closing its eyes” to the risk of a second disaster. He has joined protest demonstrations against the plant reopenings.

“There is a clear conflict between government policy and the wishes of the public,” he said. “Additional protective measures against tsunamis have been taken, such as raising the protective walls, but I don’t think they go far enough. We shouldn’t be building nuclear power plants in areas where there is a population to be affected. After the tsunami, Japan went without nuclear power for years, so it can be done.”…….. http://www.telegraph.co.uk/news/worldnews/asia/japan/12184114/Fukushima-Tokyo-was-on-the-brink-of-nuclear-catastrophe-admits-former-prime-minister.html

Sucked into nuclear power plant pie – scuba diver

Scuba diver sucked into nuclear power plant pipe relives horrific experience living in ‘complete darkness’ , Mirror UK,  6 MAR 2016 BY 

Christopher Le Cun was in complete darkness when he was sucked through a 16ft-wide nuclear plant water pipe. A scuba diver broke down in tears after reliving the harrowing ordeal of when he was sucked into a nuclear plant water pipe and was forced to contemplate suicide.

Christopher Le Cun was diving off the coast of Hutchinson Island in South Florida when he was suddenly gulped “like a wet noodle” into the huge pipe – which pulls through 500,000 gallons of water a minute and is used to cool nuclear reactors.

The pipe is 16ft wide and a quarter of a mile long.

Christopher – who is launching a legal case against the owners of the nuclear plant, Florida Power and Light (FPL) – said he was in complete darkness when he was sucked into the giant tube, and couldn’t see a hand in front of his face.

Because the pipe at the St Lucie Nuclear Power Plant is so long it took Christopher five whole minutes before he reached its end………. http://www.mirror.co.uk/news/uk-news/scuba-diver-sucked-nuclear-power-7504504

Radiation exposure to 20 workers at Faslane nuclear base

Workers exposed to radiation at Faslane nuclear base, Scotsman, 5 Mar 16  Twenty workers were exposed to radiation at the Faslane nuclear base as a result of a safety breach, according to newly released documents.

The workers were inadvertently exposed to a low dose of ionising radiation as they were repairing a leaking tank on a Trident nuclear weapons submarine at the same time a nearby reactor was undergoing trials………[other radiation incidents at Faslane] ……

SNP defence spokesperson Brendan O’Hara MP said: “The MoD – once again – stands accused of a very poor approach to radiation safety at the Faslane base……..

‘’These incidents and how they were subsequently handled, pose real and serious questions , not just about nuclear safety procedures at the base – but also whether the regulator the ONR is doing enough – and quickly enough – to address these concerns.

‘’The MoD must investigate and explain why these failings occur and lay out precisely what it is doing to get it sorted.’’……..http://www.scotsman.com/news/workers-exposed-to-radiation-at-faslane-nuclear-base-1-4046659

Design flaws in America’s nuclear reactors: NRC engineers call for shutdown, if not fixed

safety-symbol1Flag-USANRC engineers urge shutdown of nuclear plants if design flaw not fixed, Utility Dive By  | March 3, 2016 

Dive Brief:

  • A group of engineers in the U.S. Nuclear Regulatory Commission say they have identified a design flaw in nearly all nuclear reactors in the country that should result in their mandatory shutdown unless operators fix the problem, Reuters reports.
  • In late February, the engineers petitioned the NRC to order immediate enforcement actions to correct the design flaw, which they say could result in damage to cooling systems and ultimately lead to an emergency situation. The filing asks the agency to respond by March 21 and is a part of a standard NRC process, according to the news outlet.
  • The filing stems from an incident in January 2012, when Exelon’s Byron 2 unit in Illinois experienced an automatic reactor trip from full power after an undervoltage condition was detected. The unit was shut down for a week, in what is known as an open phase condition created by an unbalanced voltage. The NRC engineers say such an event could cause an electrical short, reducing the abilituy of cooling systems to operate.

Dive Insight:

In a little-noticed public filing, a group engineers from within the NRC are calling for an investigation into the nuclear vulnerability, and why it has not been fixed when the issue has been known since Exelon’s 2012 event.

Union of Concerned Scientists nuclear expert Dave Lochbaum told Reuters the agency “snatched defeat from the jaws of victory,” with its failure to address the issue after it became known in 2012. And the engineers say there has been at least 13 open phase events over the past 14 years.

Lochbaum said it was a positive sign the engineers filed, indicating no fear of reprisals. But the issue means “something is not right with the safety culture at the agency.” ……..http://www.utilitydive.com/news/nrc-engineers-urge-shutdown-of-nuclear-plants-if-design-flaw-not-fixed/414919/#.VthYQXYJX1Y.twitter

Nuclear reactor outage caused by bird droppings

Bird poop apparently caused New York nuclear reactor outage http://www.cbsnews.com/news/bird-poop-apparently-caused-new-york-nuclear-reactor-outage/ALBANY, N.Y. — Bird poop was the likely cause of a December shutdown at a nuclear power plant outside New York City, according to the operator.

An Indian Point reactor safely shut down for three days starting Dec. 14 following an electrical disturbance on outdoor high voltage transmission lines, Entergy Corp. said. An outside expert is analyzing whether what’s technically called bird “streaming” was the culprit.

In a report to the Nuclear Regulatory Commission last month, the New Orleans-based company said the automatic reactor shutdown was apparently from bird excrement that caused an electric arc between wires on a feeder line at a transmission tower.

“If it has nowhere to send its electricity, the generator senses that and automatically shuts down,” Entergy spokesman Jerry Nappi said.

Plant managers told the NRC they were revising preventive maintenance for additional inspection and cleaning and installing bird guards on transmission towers.

Nappi said he couldn’t recall a similar incident in the past several years from birds at Indian Point, which is located along the Hudson River north of New York City. He didn’t immediately know what type of bird was suspected. No carcass was found, he said.

Nuclear Regulatory Commission spokesman Eliot Brenner said it’s not uncommon for wildlife to trigger electrical outages on transmission lines regardless of the generation source of the electricity. “Squirrels are the biggest offenders,” he said.

He didn’t know if the NRC was specifically tracking animal-related reactor outages. “They’re kind of few and far between, but certainly not unheard of,” he said.

A recent radioactive leak at the plant had prompted renewed calls for the site to be shut down, amid growing concerns about the potential damage a nuclear accident could cause in one of the most densely populated parts of the country. In the past year alone there have been a number of mishaps at Indian Point, including a power failure in the reactor core, a transformer fire, an alarm failure, and the escape of radiated water into groundwater. The plant sits about 25 miles north of New York City.

Neil Sheehan, a representative for the U.S. Nuclear Regulatory Commission, told CBS News last month that the NRC is continuing to review the recent tritium leakage at Indian Point.

“We recently sent a radiation protection specialist to the plant to assess the situation and learn more about what happened. He was assisted by our three Resident Inspectors assigned to the plant on a full-time basis,” he said in an email.

NRC is also currently reviewing Indian Point’s renewal license, which would authorize it to continue operating for another 20 years. But environmental groups say the region needs to utilize other options to meet its energy needs.

The danger of flying nuclear materials between UK and USA

MoD admits flying nuclear materialssafety-symbol1 http://www.theguardian.com/uk-news/2016/mar/01/mod-admits-flying-nuclear-materials-between-uk-and-us

Campaigners highlight safety risks after defence minister admits there have been 23 such flights in the last five years, Guardian, , 1 Marc 16 , Materials used in nuclear weapons have been flown between the UK and the US 23 times in the last five years, the Ministry of Defence has admitted.

Though the MoD does not give details, the flights are believed to have carried tritium, plutonium and enriched uranium, all vital ingredients of Tridentwarheads. They probably started or ended at the RAF base at Brize Norton in Oxfordshire.

The flights have alarmed politicians and campaign groups, who are worried about accidents causing widespread radioactive contamination. The MoD, however, insists that the transports complied with stringent safety rules.

The Guardian reported on 9 February that two MoD emergency exercises in 2011 and 2012 codenamed Astral Bend envisaged planes carrying nuclear materials crashing. One imagined a leak of enriched uranium and plutonium spreading up to five kilometres across south Wales.

That prompted a question about the nuclear flights in the House of Commons last week by the Scottish National party’s defence spokesman, Brendan O’Hara MP. In response, the government admitted the frequency of such flights for the first time. “In the last five years, 23 flights carrying defence nuclear materials were undertaken,” the defence minister, Penny Mordaunt, told MPs in a written answer.

“All flights were between the UK and the United States on fixed-wing aircraft under the control of UK armed forces.” Details of the cargoes were kept secret “as disclosure would or would be likely to prejudice national security,” she said.

O’Hara said: “This answer is alarming and highlights a practice most of the public are unaware of. The MoD need to outline what risk and safety assessments they made about these flights and precisely when and what areas of UK airspace were used. I fear the MoD does not have a great track record on transparency when it comes to nuclear issues – and this answer clearly begs more questions.”

Experts say that the UK and the US regularly exchange tritium, plutonium and enriched uranium under a mutual defence agreement. Anti-nuclear campaigners have tracked road convoys transporting nuclear materials between the nuclear bomb plants at Aldermaston and Burghfield in Berkshire and RAF Brize Norton.

The independent nuclear engineer, John Large, argued that the MoD’s air shipments would not comply with international safety regulations for civil nuclear transports. A crash could “contaminate large tracts of land with potential radiological consequences for unprotected members of the public”, he said.

Tom Clements, who heads a group monitoring a nuclear weapons plant at Savannah River in South Carolina, claimed that the MoD flights would not meet US standards for civil nuclear shipments. The flights had “disturbing” implications for the world’s attempts to reduce the proliferation of nuclear weapons, he said.

Peter Burt from the UK Nuclear Information Service, a not-for-profit group, highlighted the high risks of air shipments. “The RAF regularly fly nuclear materials over large urban areas such as Bristol, Cardiff, and Swansea, which raises serious questions about what would happen in the event of an accident involving one of these flights,” he said.

The MoD maintained that the air transports were safe. “The transport of defence nuclear materials is carried out to the highest standard in accordance with stringent safety regulations,” said an MoD spokeswoman.

“In over 50 years of transporting defence nuclear materials in the UK, there has never been an incident that has posed any radiation hazard to the public or to the environment.”

Danger of an aging nuclear power plant next to a natural gas pipeline.

There’s a proposed natural gas pipeline next to a nuclear power plant. What could go wrong? Grist By  on 29 Feb 2016  What’s scarier than an aging nuclear power plant? An aging nuclear power plant next to a natural gas pipeline.

That could be the new reality for the Indian Point Energy Center, a nuclear power station located in Westchester County, just 45 miles north of Manhattan. A proposed expansion of a natural gas pipeline across the power station’s property has environmentalists and other groups concerned that an accident could turn the power plant into an unrivaled disaster. It’s a bit like smoking next to a gas tank — a gas tank filed with nuclear fuel near one of the densest population centers on the planet.

Despite how ill-advised this sounds, the pipeline has already been approved by the Federal Energy Regulatory Commission. Why would they allow such a thing? Well, as the New York Times notes, approval was partly based on reviews carried out by the Entergy Corporation — which happens to be the same company that owns the plant.

New York Gov. Andrew Cuomo, a resident of Westchester County, is not having any of it. Cuomo recently directed his administration to conduct an independent safety analysis of the pipeline project after hearing that radioactive water had leaked from the aging plant and into the groundwater. This is just the latest strike against Indian Point by the Cuomo administration, which called for the plant’s closure last year. “The safety of New Yorkers is the first responsibility of state government when making any decision,” said the governor in a statement.

Cuomo isn’t alone. In Nov. 2015, a group of climate activists known as the Montrose 9 blocked construction of the pipeline, which would transport natural gas from Texas to Massachusetts. In addition to the activists’ concerns about the affects of burning natural gas on the climate, they targeted the Spectra-owned pipeline for its proximity to Indian Point, which the federal government previously listed among the nation’s worst power plants.

The Nuclear Regulatory Commission, however, seems unconcerned. ……http://grist.org/business-technology/theres-a-proposed-natural-gas-pipeline-next-to-a-nuclear-power-plant-what-could-go-wrong/

Engineers concerned at design flaw in US nuclear reactors

U.S. NRC engineers urge fix for nuclear power stations Reuters, By Timothy Gardner 1 Mar 
A group of engineers within the U.S. nuclear power regulator is concerned that a design flaw in nearly all U.S. nuclear plants could endanger emergency core cooling systems. The group has urged the regulator to order power station operators to either fix the problem or face mandatory shutdowns.

Seven engineers in late February petitioned the Nuclear Regulatory Commission to order immediate enforcement actions against licensees of U.S. nuclear power plants, in a little-noticed, but public move.

The petition, filed under a standard NRC process, urges the agency to respond by March 21.

The engineers are concerned that a design flaw in nearly all U.S. nuclear facilities leaves them vulnerable to so-called open phase events in which an unbalanced voltage, such as an electrical short, could cause motors to burn out and reduce the ability of a reactor’s emergency cooling system to function. If the motors are burned out, backup electricity systems would be of little help, the petition said.

In early 2012 an unbalanced voltage event forced Exelon Corp’s Byron 2 reactor in Illinois to shut down automatically. The unit was shut for about a week.

Later that year, the NRC alerted nuclear power plant operators in a bulletin to a potential design vulnerability concerning open phase and collected feedback from the operators.

But the agency never ordered the plants to make changes to reduce any open phase vulnerabilities. The petition said 13 open phase events have occurred at U.S. and international nuclear plants over the last 14 years……http://www.reuters.com/article/usa-nuclear-regulator-idUSL2N1692BF

Theft of radioactive material in Mexico

Mexico issues alert after theft of radioactive material, ABC News 29 Feb 16  Five Mexican states have been put on alert after a truck carrying a container of potentially dangerous radioactive material was stolen, the Interior Ministry says.

The National Co-ordination of Civil Protection issued the warning after a company in the central state of Queretaro reported that a ute carrying radioactive iridium-192 had been stolen.

The Ministry said the material “can be dangerous for people if not handled safely” and could cause “permanent or serious injury to a person who is handling or in contact with it for a short time”.

Such damage could occur after contact lasting anywhere from minutes to hours, it added.

Officials said the radioactive material represented a significant health risk if taken outside its container, but was not dangerous if kept sealed…….http://www.abc.net.au/news/2016-02-29/mexico-issues-alert-after-theft-of-radioactive-material/7209140

Indian Point nuclear plant’s 65,000% Spike In Radiation

text ionisingFlag-USA65,000% Spike In Radiation Outside New York Nuclear Plant Is Likely Worse Than Fukushima, Activist Post  FEBRUARY 27, 2016 BY JAY SYRMOPOULOS Buchanan, NY — An uncontrollable radioactive flow from the Indian Point nuclear power plant continues leaking into groundwater, which leads to the Hudson River, raising the specter of a Fukushima-like disaster only 25 miles from New York City.

The Indian Point nuclear plant is located on the Hudson River, approximately 25 miles North of NYC, and serves the electrical needs of an estimated 2 million people. Last month, while preparing a reactor for refueling, workers accidentally spilled some contaminated water, containing the radioactive hydrogen isotope tritium, causing a massive radiation spike in groundwater monitoring wells, with one well’s radioactivity increasing by as much as 65,000 percent.

Entergy, the Louisiana-based company that owns the plant, chalked up the readings to “fluctuations that can be expected as the material migrates.” According to Entergy, the tritium contaminated water spill was contained within the plant, and never reached the Hudson or any other water source.

“There is no impact to public health or safety,” Entergy spokeswoman Patricia Kakridas told RT.

Of course, the tritium leak is the ninth in just the past year, four of which were serious enough to shut down the reactors. But the most recent leak, however, according to an assessment by the New York Department of State as part of its Coastal Zone Management Assessment, contains a variety of radioactive elements such as strontium-90, cesium-137, cobalt-60, and nickel-63, and isn’t limited to tritium contamination.

Despite the assurances from Entergy, the area around Indian Point is a “cancer cluster,” with the local rate of thyroid cancer rates registering at 66 percent higher than the national average, according to Joseph Mangano, Executive Director of the Radiation and Public Health Project (RPHP).

The end of the nuclear age – foreshadowed as Indian Point nuclear station leaks radioactivity

Indian Point Leak Foreshadows the End of the Nuclear Age, Fortune by  David Z. Morris @davidzmorris
 FEBRUARY 28, 2016, New York could be the next Fukushima as world governments roll back nuclear power.

The Indian Point nuclear power plant in New York State is leaking radioactive contaminant into nearby groundwater, and despite plant operator Entergy’s  ELA 0.08%  assurances that the leak has “no health or safety consequences,” Governor Andrew Cuomo called earlier this month for a full investigation by state environment and health officials.

The latest revelations add to a mounting list of recent accidents and problems at Indian Point, and Cuomo’s hard stance is nothing new, either. As of November of last year, Cuomo’s office actively opposed the continuing operation of Indian Point.

reactor-Indian-Point

The plant’s problems are not isolated—leaks have been found at as many as 75% of U.S. nuclear plants. And closing Indian Point would put New York, and the U.S., in line with a sharp global move away from nuclear power following 2011’s meltdown at Japan’s Fukushima Daichi reactor. Japan shut down all of its nuclear plants after the disaster, and only began tentatively restarting a handful in 2015.

Countries including France and Germany have moved to similar phase-outs, with Germany in 2011 pledging to phase out all nuclear power by 2022. Austria and Spain have stopped all construction on new nuclear plants. The U.S. had not constructed a new nuclear power plant in nearly twenty years when, in October of 2015, a plant in Tennessee was given the go-ahead.

Nuclear plants represent huge threats to nearby areas, though the risk of a disaster at any one plant is small. While Stanford researchers have found that Fukushima’s fallout may directly cause only about 300 deaths worldwide, estimates of economic losses range from $250-$500 billion, stemming largely from the removal of 159,128 people from a zone the size of Connecticut—land which will be uninhabitable for centuries.

Fukushima prefecture had a population just short of two million at the time of the disaster. Indian Point sits just 25 miles north of New York City’s 8.5 million inhabitants, as well as real estate many times more valuable than that in northern Japan. During the Fukushima meltdown, the Japanese government established a 20 kilometer (12 mile) evacuation zone around the reactor—but the U.S. embassy recommended that Americans leave areas within 50 miles.

That suggests that a meltdown at Indian Point could lead to the evacuation of New York City. In addition to profound human costs, the immediate economic damage would run into many trillions of dollars. And it is no exaggeration to say that a threat to New York City is a threat to the entire U.S. economy, which it plays a key role in organizing……. http://fortune.com/2016/02/28/indian-point-end-of-nuclear-age/
