More evidence of safety risks: Hunterston B nuclear reactors should be closed
The Ferret 17th Oct 2019, Hunterston, The graphite cores of two ageing nuclear reactors at Hunterston in North Ayrshire have begun to crumble as cracks spread, prompting safety inspectors to impose tough new conditions threatening future operations.
Technical reports released by the UK government’s Office for Nuclear
Regulation (ONR) reveal that at least 58 fragments and pieces of debris
have broken off the graphite bricks that make up the reactor cores.
According to ONR there is “significant uncertainty” about the risks of
debris blocking channels for cooling the reactor and causing fuel cladding
to melt. This could cause an accident and a leak of radioactivity.
The 50-strong group of Nuclear Free Local Authorities (NFLA) is urging ONR to close down both reactors at Hunterston. “These latest alarming
revelations about the graphite reactor cores at Hunterston B starting to
crumble and potential issues with the fuel make us even more convinced that
reactor three should not be allowed to resume operation,” said NFLA
Scotland convener and Glasgow SNP councillor, Feargal Dalton.
“We will be pressing the Office for Nuclear Regulation very hard to examine very carefully any justification which EDF Energy puts forward to reopen reactor four after its initial four month trial, and to be open and transparent
about what they find.
The precautionary principle would suggest that this reactor too should stay closed.” NFLA radiation consultant, Dr Ian Fairlie, described ONR’s latest reports as “very worrying”. By considering the melting of fuel cladding the regulatory agency was “getting into even more dangerous matters than before”. He added:
“These reports and their harder language make one wonder why ONR granted
a four month extension to reactor four in August. Taken together the new
revelations strengthen the calls by local residents to close both reactors
at Hunterston B.” https://theferret.scot/hunterston-graphite-debris-nuclear/
Safety concerns over Berkshire nuclear weapons factories
Safety concerns over Berkshire nuclear weapons factories, BBC, 17 Oct 19, Two nuclear weapons factories are to remain under extra scrutiny due to safety concerns over their ageing facilities, a government watchdog said. BBC News
The AWE sites in Aldermaston and Burghfield, Berkshire, make and maintain the UK’s nuclear warheads.
The Office for Nuclear Regulation (ONR) said the sites will be scrutinised closely for at least two years.
Contractor AWE Plc said the replacements for the outdated facilities had been delayed.
The private company manufactures the warheads for Trident, the UK’s nuclear deterrent at sea.
AWE had planned to replace the Burghfield facilities by 2016, but due to construction delays it is expected to be completed in 2023, according to the Local Democracy Reporting Service. …. https://www.bbc.com/news/uk-england-berkshire-50099579
A single bird grounds America’s Navy ‘Doomsday’ plane
Navy ‘Doomsday’ plane built to withstand nuclear attack grounded after striking single bird, By JESSICA SCHLADEBECK, NEW YORK DAILY NEWS |OCT 18, 2019 The Navy’s “Doomsday Plane,” designed to withstand even a nuclear attack, suffered millions of dollars in damages after striking a single bird as it practiced a landing maneuver earlier this month at a Maryland air station.

Switzerland’s old Beznau nuclear power plant
|
The world’s oldest nuclear power plant, By Jack Unwin Power Technology, 16 Oct 19, A look at Beznau nuclear power plant in Switzerland, the world’s oldest nuclear power plant currently in operation…….
Construction on the plant began in 1965 and Beznau 1 began producing power on 1 September 1969, with Beznau 2 following in 1972. It has two pressurised water reactors (PWR) built by Westinghouse with a capacity of 365MW each, for a total capacity of 730MW and able to produce 6000 gigawatt-hours (GWh) of energy. The plant is owned and operated by Swiss private company Axpo Holdings.
Accidents will happenDespite its long run producing power, Beznau has been no stranger to accidents at its site. According to the Swiss Federal Nuclear Safety Inspectorate, there were 91 nuclear security incidents between 1995 and 2014. However 86 of these were at level 0 on the International Nuclear Event Scale (INES), the least severe on its scale. Four were at level 1 and one in 2009 that was level 2, when two workers at the plant were exposed to “inadmissible” levels of radiation . Following its reopening four incidents were recorded at in 2018.
Protests and closureProtestors in Switzerland have targeted Beznau in particular, and nuclear power in general. Following the Fukushima nuclear disaster in Japan in 2011, 20,000 protestors gathered in the town of Doettingen to condemn Beznau in the largest anti-nuclear protest in the country for 25 years. In 2014 100 Greenpeace activists broke into Beznau and scaled one of the buildings at the site with a banner proclaiming “the end” of nuclear power due to safety concerns for the ageing plant. These concerns appeared to be well-founded in October 2015 when Beznau 1 was found to have 1000 holes, cracks and indentations around the reactor. Beznau was closed for repairs when “anomalies” were found in its steam generators from March 2015 to March 2018. The future of nuclear power in SwitzerlandDespite still producing power and being one of five nuclear plants that form35% of Switzerland’s energy mix, Beznau and nuclear power itself is under threat. Switzerland will instead develop renewable energy from wind, solar and hydropower as part of its Energy Strategy 2050 plan. Meanwhile there will be no new general licenses for nuclear power plants, but old plants like Beznau will continue to run until they are decommissioned…..https://www.power-technology.com/features/worlds-oldest-nuclear-power-plant/ |

Risks of nuclear transportation
|
Safer nuke shipments? Critics split on whether tech has cut nuclear transportation risk, reno gazette journal, Scott Sonner, Associated Press Oct. 14, 2019 “…… Today, radioactive shipments are hauled in double-walled steel containers inside specialized trailers that undergo extensive testing and are tracked by GPS and real-time apps.But whether shipping technology has evolved enough to be deemed safe depends on whom you ask.
The Trump administration’s revival of a decades-old plan to move the nation’s most dangerous radioactive waste to a remote spot in the Nevada desert has reignited a long-running fight in the courts and Congress over how to safely get the hazardous remnants of decades of bomb-making and power generation to a permanent resting place. “It seems to me, that part of the gist of the government’s argument is that, ‘We’ve been doing this a long time. We know what we are doing. You have to trust us,’” noted U.S. District Judge Miranda Du who’s considering a lawsuit Nevada filed against the Energy Department over waste being sent there. For its part, the government says there are no safety concerns………. But there have been close calls, said Robert Halstead, an analyst who has studied the dangers of transporting radioactive waste for 35 years and is head of Nevada’s Agency for Nuclear Projects. A truck crash in 1971 killed a driver and propelled a cask full of nuclear waste into a ditch in Tennessee. The container was damaged, but no radioactive material leaked. More recently a Tennessee contractor revealed earlier this year it may have mislabeled low-level nuclear waste – items such as contaminated equipment or workers’ clothing – that potentially was sent to Nevada over six years without the proper safeguards. The Energy Department responded by announcing in July it will review all radioactive waste packaging and shipping. Perhaps the greatest point of disagreement is whether the “rigorous testing” is rigorous enough. It would be dangerous and expensive to run tests involving explosions, fire or other hazards on a real cask of spent nuclear fuel. So it’s never been done in the United States. “What isn’t clear is: ‘What are the conditions under which the package would fail?” said Edwin Lyman, head of the nuclear safety project at the Union of Concerned Scientists, who has studied the hazards of nuclear shipments for 25 years. There’s enough high-level nuclear waste awaiting disposal in the U.S. to fill a football field 65 feet deep. Few states want to house it within their borders. To solve the long-time problem, the Trump Administration has revived a decades-old plan to move the nation’s most dangerous radioactive waste from around the country to a site 90 miles northwest of Las Vegas, the Yucca Mountain Nuclear Waste Repository. It was proposed to hold 77,000 tons of highly radioactive spent nuclear fuel in a maze of tunnels bored into an ancient volcanic ridge. Nevada doesn’t want it. The state and its congressional delegation have been fighting the project and other attempts to store nuclear waste in Nevada for decades, and the Yucca Mountain project was shelved in 2010 under pressure from then-Senate Democratic Majority Leader Harry Reid of Nevada and President Barack Obama. U.S. Rep. Dina Titus, a Nevada Democrat who helped defeat a GOP-led effort to restore funding to Yucca Mountain last May, called it “the latest attempt to force nuclear waste down Nevada’s throats.” Meanwhile, the state has sued the federal government over the half metric ton of plutonium secretly shipped from South Carolina to the Nevada National Security Site. That site is separate from but close to the Yucca Mountain site. While U.S. leaders battle over where to ship the nuclear waste, the government says it has upgraded transportation containers and the way it hauls the material………..https://www.rgj.com/story/news/2019/10/14/critics-split-whether-tech-has-cut-nuclear-transportation-risk/3978815002/ |

Is UK’s regulator of Hinkley nuclear project ignoring the seismic risks of fracking in the area?
Drill or Drop 12th Oct 2019, Hinkley. The safety regulator for the nuclear industry has no information about the risk of earth tremors from fracking near the Hinkley Point power station, a campaign group has revealed. Frack Free Exmoor, Quantocks and Sedgemoor.
(FFEQS) has also shown that the Office for Nuclear Regulation (ONR) has had no correspondence on the subject with either the oil and gas industry regulator, the power station operator, local exploration companies or Somerset County Council. FFEQS has described the failure to assess the risk of fracking on the nuclear station, which includes the new Hinkley Point C facility, as “a gaping hole” in the safety case.
In August 2019, fracking by Cuadrilla near Blackpool caused more than 130 earth tremors, including the UK’s largest fracking-induced seismic event, measuring 2.9ML. This tremor led to formal complaints of cracks to walls, windows and doors to about 100 properties, DrillOrDrop understands. Hinkley Point is a few miles from an area where the exploration company, South Western Energy, has indicated it is interested in drilling for hydrocarbons (DrillOrDrop report).
Opposition to fracking appears to be growing in the region.
Sedgemoor District Council voted unanimously on 9 October 2019 to be a Frack Free zone. This follows previous similar votes in Somerset West and Taunton councils.
Russia’s fatal Skyfall missile test- a fatal nuclear accident
- A report from a US State Department official on Thursday provides a clearer picture as to how the August 8 Skyfall accident occurred at a secret Russian military testing range.
- “The United States has determined that the explosion near Nyonoksa, Russia, was the result of a nuclear reaction that occurred during the recovery of a Russian nuclear-powered cruise missile,” the official wrote. “The missile remained on the bed of the White Sea since its failed test early last year, in close proximity to a major population centre.”
- Amid confusion and obfuscation from Russia and speculation from analyst, the report gives a clearer picture of how the accident, which killed seven Russians, occurred.
A report to the UN General Assembly First Committee on Thursday by Thomas G. DiNanno, the deputy assistant secretary and senior bureau official at the State Department’s Bureau of Arms Control, Verification, and Compliance, ended months of speculation about the exact cause of the accident, which killed seven Russians.
While experts at the time determined that the cause was a nuclear-reactor explosion and tied it to the 9M730 Burevestnik nuclear-powered cruise missile, which NATO calls the SSC-X-9 Skyfall, DiNanno’s report gives a clearer picture of how the accident occurred.
After the accident, Russia’s explanations and reactions to it varied greatly, from ordering an evacuation of the area to canceling it hours later. Four radiation sensor sites also went mysteriously offline after the accident, pointing to a potential cover-up. Russian officials said they were not obligated to share the data, which could have helped point to the cause of the accident, The New York Times reported.
Officials also declined to tell doctors treating engineers affected by the blast that they had been exposed to nuclear radiation and requested hospital staff sign a nondisclosure agreement, The Moscow Times originally reported……. https://www.businessinsider.my/us-putins-skyfall-missile-failed-test-and-exploded-during-recovery-2019-10/

Drones a threat to nuclear facilities
Korea Times 6th Oct 2019, National infrastructure sites are vulnerable to possible drone strikes, with a growing number of intrusions at nuclear power plants here using the small unmanned aircraft being confirmed, according to a lawmaker, Sunday.
Rep. Lee Sang-min of the ruling Democratic Party of Korea (DPK) said the
Nuclear Safety and Security Commission (NSSC) reported 13 cases of the
illegal flying of drones near the power plants from 2015 to 19. Ten of the
13 cases occurred just in 2019 ― and six took place near the Kori Nuclear
Power Plant in northern Busan in August.
https://www.koreatimes.co.kr/www/tech/2019/10/133_276717.html
Bulletin of Atomic scientists 4th Oct 2019, A terrorist attack by swarming drones may seem farfetched, and it is important not to engage in hyperbole. However, scenarios similar to this are playing out around the world, often in a hostile manner. Once again, the recent attacks on Saudi Arabia should give pause for concern. At least 18 drones and seven cruise missiles were reportedly used to break through national defenses and strike the designated targets in Abqaiq and Khurais.
The use of these systems in swarms makes tactical sense, as it increases
the likelihood of a successful strike, by overwhelming and saturating
defenses. Drones may also be used to help identify targets, allowing
secondary systems to strike with precision. In a different, but not
unfamiliar manner, swarms have been used for saturation, spotting, and
strike purposes by both criminal gangs and terrorists.

Massive Nuclear Explosion similar to Kyrshtym by Mayak Can Happen Happen at Hanford if the site is not Monitored and tanks not taken care of
Lane, 6 Oct 19 Mayak Explosion
Ten Thousand Gallon Tank at Mayak Exploded from Heat Decay. The Heat Deacy was from Strontium 90, Cesium 137, Cobalt 60 and Plutonium Stored in the Underground Tank. The explosion was equivalent to 100 tons of TNT. There are55 million gallons of the same Radionuclide Mix stored at Hanford, in UnderGround Tanks. If they become too concentrated and hot, the same thing will Happen there, contaminating a Great Portion of the Pacific NW USA and southe western Canada.

In 1957 the cooling system in one of the tanks containing about 70–80 tons of liquid radioactive waste failed and was not repaired. The temperature in it started to rise, resulting in evaporation and a chemical explosion of the dried waste, consisting mainly of ammonium nitrate and acetates (see ammonium nitrate/fuel oil bomb). The explosion, on 29 September 1957, estimated to have a force of about 70–100 tons of TNT,[10] threw the 160-ton concrete lid into the air.[8] There were no immediate casualties as a result of the explosion, but it released an estimated 20 MCi (800 PBq) of radioactivity. Most of this contamination settled out near the site of the accident and contributed to the pollution of the Techa River, but a plume containing 2 MCi (80 PBq) of radionuclides spread out over hundreds of kilometers.[11] Previously contaminated areas within the affected area include the Techa river, which had previously received 2.75 MCi (100 PBq) of deliberately dumped waste, and Lake Karachay, which had received 120 MCi (4,000 PBq).[7]
In the next 10 to 11 hours, the radioactive cloud moved towards the north-east, reaching 300–350 km (190–220 mi) from the accident. The fallout of the cloud resulted in a long-term contamination of an area of more than 800 to 20,000 km2 (310 to 7,720 sq mi), depending on what contamination level is considered significant, primarily with caesium-137 and strontium-90.[7] This area is usually referred to as the East-Ural Radioactive Trace EURT
Russia’s deadly explosion in August has awakened Russians to the nuclear danger
|
Blast, Radiation Unnerve Russians Living Near Test Site Deadly August explosion during missile trial was wake-up call; ‘We’re worried it could happen again’ WSJ, By Ann M. Simmons The Wall Street Journal, Sept. 25, 2019 SEVERODVINSK, Russia—For decades, the Russian military conducted trials at a restricted site near this northern city, testing missiles that Moscow loaded onto Cold War-era submarines. Residents paid little heed for years. That changed on Aug. 8, when an explosion during a missile test killed at least seven people and caused radiation levels to spike in the area around Severodvinsk. U.S. officials said the explosion confirmed that Russia is endeavoring to develop high-grade specialized nuclear weapons, as Moscow makes fresh efforts to produce a new generation of arms capable of overcoming U.S. defense systems. University student Alexandra Volkova closed all her windows when she heard about the blast hours after it occurred, but is afraid she acted too late. “I’m not sure if I have been exposed to radiation,” the 22-year-old said. “I’m not sure whether it’s a serious problem. I’m not sure whether I should have taken some iodide.”……… Russian President Vladimir Putin said the incident occurred during the test of a “promising weapons system” and praised the personnel who perished as national heroes.
The demise in August of the 1987 Intermediate-range Nuclear Forces Treaty lifted decades-old constraints on Russia and the U.S. on developing nuclear and conventional ground-based ballistic and cruise missiles with ranges of 300 to 3,400 miles.
It is now unclear whether a parallel accord, New START, which limits U.S. and Russian long-range nuclear arms, will be renewed when it expires in 2021. The Kremlin hasn’t named the weapon that was being tested in the explosion in an area called Nyonoksa, which a CIA report declassified in 2013 described as a prominent weapons testing site. Experts believe the explosion resulted from Russia’s failed test of its nuclear-powered Burevestnik missile, known as Skyfall, which it started developing in the 2000s. Mr. Putin unveiled the weapon last year in a slick animated video, showcasing a guided missile gliding untracked over oceans and circumventing air-defense systems. The Kremlin has described the missile as virtually unstoppable, with potentially unlimited range and an unpredictable flight pattern. Little is publicly known about it. Matt Korda, a research associate for the Nuclear Information Project at the Federation of American Scientists in Washington, said it wouldn’t be an overstatement to describe it as “a kind of flying Chernobyl,” referring to the 1986 nuclear accident at this Soviet nuclear power plant.
If completed, Skyfall would be an “unshielded nuclear reactor that’s essentially just flying around pumping out radiation,” Mr. Korda said. The accident sowed concerns among residents around Severodvinsk, home to a naval base and around 183,000 people. “As far as we knew, there was never any nuclear testing here and there had never been any accidents with radiation involved,” said Oleg Mandrykin, a businessman and environmental activist in the city. “People died because of this explosion, because of high exposure to radiation,” he said. “Now people here are worried because they just don’t understand what happened.” Russian authorities’ Soviet-era style secrecy in the aftermath of the explosion exacerbated fears. A notice on the Severodvinsk city website announcing a spike in radiation levels following the blast was quickly deleted. An initial order for residents of Nyonoksa to evacuate was canceled. And at least four Russian monitoring stations designed to detect nuclear radiation were switched off soon after the blast, the Comprehensive Nuclear-Test-Ban Treaty Organization said. Authorities in Severodvinsk, where foreigners still need official permission to visit, didn’t respond to requests for comment on the statements following the incident and accusations that officials are deceiving the public about the severity of the radiation and the current risk. https://www.wsj.com/articles/blast-radiation-unnerve-russians-living-near-test-site-11569403801

NRC weakens safety measures at nuclear power plants
A Meltdown in Nuclear Security A commando raid on a nuclear power plant seems the stuff of Hollywood. So why are nuclear security experts so worried? U.S. News, By Alan Neuhauser Staff Writer, Sept. 20, 2019 IT RANKS AMONG THE worst-case scenarios for a nuclear power plant: an all-out assault or stealth infiltration by well-trained, heavily armed attackers bent on triggering a nuclear blast, sparking a nuclear meltdown or stealing radioactive material.
For nearly two decades, the nation’s nuclear power plants have been required by federal law to prepare for such a nightmare: At every commercial nuclear plant, every three years, security guards take on a simulated attack by hired commandos in so-called “force-on-force” drills. And every year, at least one U.S. nuclear plant flunks the simulation, the “attackers” damaging a reactor core and potentially triggering a fake Chernobyl – a failure rate of 5 percent.
In spite of that track record, public documents and testimony show that the Nuclear Regulatory Commission, the federal agency responsible for ensuring the safety and security of the nation’s fleet of commercial nuclear reactors, is now steadily rolling back the standards meant to prevent the doomsday scenario the drills are designed to simulate.
Under pressure from a cash-strapped nuclear energy industry increasingly eager to slash costs, the commission in a little-noticed vote in October 2018 halved the number of force-on-force exercises conducted at each plant every cycle. Four months later, it announced it would overhaul how the exercises are evaluated to ensure that no plant would ever receive more than the mildest rebuke from regulators – even when the commandos set off a simulated nuclear disaster that, if real, would render vast swaths of the U.S. uninhabitable.
Later this year, the NRC is expected to greenlight a proposal that will allow nuclear plants – which currently must be able to fend off an attack alone – to instead begin depending on local and state law enforcement, whose training, equipment and response times may leave them ill-prepared to respond to a military-grade assault.
The moves have inflamed open dissent within the commission, which has been riven in recent years by internecine conflict between Republican and Democratic commissioners…….
Nuclear security experts, consultants, law enforcement veterans and former NRC commissioners – several of whom spoke with U.S. News on condition of anonymity in order to address the issue candidly – are nothing short of alarmed. They openly question whether top regulators at the NRC, ceaselessly lobbied by an industry strapped for cash, have fallen prey to valuing quarterly earnings, lucrative contracts and potential plum job opportunities over day-to-day security.
A longtime nuclear security expert minced no words about the potential consequences: “I know how easy it is to cause a Fukushima-scale meltdown, radiation release or worse. And the timelines are very short. You don’t have much room to maneuver if you misjudge what the threat is,” says Ed Lyman, senior scientist in the global security program and acting director of the nuclear safety project at the Union of Concerned Scientists. “You can’t afford to be wrong once.”
‘No One Likes Security’
Force-on-force exercises, a mix of live-action role playing and military-grade laser tag, are not unique to the nuclear sector – they’re used to test military bases, and police departments engage in a version of them in active-shooter drills. For obvious reasons, they remain cloaked in secrecy.
Some details about the nuclear drills, though, are publicly available: The attacking force is expected to deploy a range of tactics, from disabling alarm systems to using automatic weapons and silencers, attacking one or multiple entry points, employing land and water vehicles, and using “incapacitating agents” and explosives. The types of attacks are explicitly outlined in NRC regulations…….
The industry has long lobbied to either eliminate the drills or, more recently, conduct them internally, with regulators relegated to the role of passive observer rather than planning and directing each exercise.
“The industry is under economic strain, so they’re looking to cut wherever they possibly can, and this is one place that they’ve been harping on for a long time to cut,” a former NRC chairman says……
Such an assault may seem the stuff of Hollywood. But intelligence assessments show that despite a spate of so-called “lone wolf” incidents in the U.S. and overseas, groups like al-Qaida and domestic terrorists in the U.S. remain as determined as ever to launch spectacular attacks. U.S. nuclear plants are at the top of the target list, experts say. …..
As recently as 2016, authorities in Belgium warned that Islamic State group operatives were planning to attack nuclear plants. The gunman who opened fire that year at a gay nightclub in Orlando worked for a contractor as a security guard at a nuclear plant in the U.S. Intelligence officials have fingered Russia in repeated cyberattacks on nuclear power plants, which could be used in conjunction with an armed infiltration.
But serious breaches have occurred even without the help of rogue insiders, heavy weaponry or foreign adversaries. With just a pair of bolt-cutters, a nun and a pair of pacifist activists in 2012 broke into a nuclear weapons complex on federal land that supposedly had higher security standards than civilian nuclear energy sites. They did little more than spray paint protest slogans, but some 30 minutes passed before guards realized a breach had occurred. Yet despite sparking a flurry of headlines and investigations, the incident prompted a collective shrug within the civilian nuclear sector, surprising security experts and contractors…….
Commissioner Baran, the lone NRC dissenting vote, later spoke out at a Senate committee hearing in April.
“We should not allow licensees to inspect themselves,” he testified. “Doing so would be fundamentally inconsistent with our role as an independent nuclear safety regulator.” Writing in a comment accompanying his vote opposing the change, he insisted that “efficiency” – or, put more bluntly, companies’ bottom lines – appeared to be the only consideration that mattered to regulators.
“Going from two NRC-conducted FOF exercises to one would provide no security benefits,” Baran wrote. Rather, one of the only benefits “would be to reduce the costs of conducting the exercises.”……
Nuclear power plant owners had long lobbied to weaken the evaluation process, former NRC commissioners say. ……..https://www.usnews.com/news/the-report/articles/2019-09-20/nuclear-power-regulators-ease-security-and-experts-sound-the-alarm
faulty parts found in a number of France’s nuclear reactors
10% of French Nuclear Reactors Have Potentially Faulty Parts Installed as Fukushima Fears Persist https://sputniknews.com/europe/201909181076832892-10-of-french-nuclear-reactors-have-potentially-faulty-parts-installed-as-fukushima-fears-persist/

by Tim Korso Most European states have taken a course to reduce to zero the use of nuclear plants since the disaster at the Japanese plant Fukushima in 2011 that led to the contamination of nearby land and sea.
Six (around 10% of the total amount) of nuclear reactors in France are using parts that had “manufacturing deviations” Electricite de France (EDF) SA, the country’s biggest power supplier reported. The irregularities were found in 16 steam generators used on nuclear power plants in Blayais, Bugey, Fessenheim, Dampierre-en-Burly, and Paluel. At the same time, EDF stated that the issue is not a pressing one and doesn’t require immediate attention. The report comes in line with an ongoing programme of reactor checks in France following the discovery of carbon-content irregularities in the steel produced by Le Creusot Forge in 2016, which made the metal weaker than usual. The checks led to the temporary suspension of numerous reactors, and a spike in energy prices both in France and in nearby states due to the former’s need to import energy to cover the deficit. Some European states have even announced their intention of completely phasing out the use of nuclear energy, gradually shutting down existing nuclear plants and aborting the construction of newer ones following the 2011 disaster at the Japanese plant Fukushima, which left significant patches of land and sea contaminated. The incident happened after the plant was hit by a powerful tsunami that knocked out its power and left reactors without cooling systems. Three countries, namely Belgium, Switzerland and Germany, are planning to eventually switch to renewable energy sources, while using gas in the transitional period. France, however, despite initially considering such option decided to keep its nuclear industry. Still, Paris opted for a reduction of its portion in the country’s energy generation from over 70% down to 50% by 2035. |
Iodine tablets for 2.2 million people in France
|
France will give out free iodine tablets to around 2.2 million people living close to nuclear plants to help protect them from radiation in case of an acciden https://eutoday.net/news/environment/2019/france-to-distribute-out-free-iodine-tablets-to-2-2-million-peoplet, Euronews reports. The country’s nuclear regulator agency ASN said on Tuesday people living within 10-20 kilometres from one of EDF’s 19 nuclear plants, as well as some 200,000 institutions including schools, will receive a letter in the incoming days informing them they can pick up the tablets from the nearest pharmacy. Previously, France distributed iodine tablets to people living within a 10 kilometre radius from a nuclear plant but has now decided to widen the radius. During nuclear accidents, radioactive iodine is released into the atmosphere that when inhaled or swallowed by the thyroid gland can cause cancer in later years. When the thyroid gland is saturated with stable iodine, it no longer absorbs the radioactive iodine. ASN said that in case of a nuclear accident, people should seek shelter in buildings and not go pick up their children from school. France is the world’s most nuclear-reliant nation, with three-quarters of its electricity produced by state-owned EDF’s 58 nuclear reactors in 19 plants spread all over the country. |
Nuclear power seems safer now? But there are hidden dangers
Reed ’21: The Hidden Dangers of Nuclear Energy, Brown Daily Herald , By ANDREW REED
STAFF COLUMNIST, September 6, 2019 “…….. for the last few decades, making reactors safer to operate has been the primary focus of nuclear engineers. In fact, nuclear engineers have said that some of the newest generation of reactors, which will begin production in 2030, will be even walk-away-safe — that is, you could relinquish all control of the reactor, forever, without incident. Inevitably, and even perhaps in my lifetime, the threat of nuclear meltdowns will be a relic of a technologically feeble era. But that’s what scares me.
Keep in mind, the concern here is not necessarily that a terrorist could themselves create a nuclear weapon. Though not impossible, there are considerable engineering challenges to doing so. Rather, the more immediate concern is a terrorist obtaining nuclear material, driving a truck filled with said material and conventional explosives into the middle of Manhattan, and detonating what is referred to as a “dirty bomb.” In doing so, they would disperse radioactive material across the city. A crude bomb of this form would, at the very least, cause extreme psychological chaos.
Many of the problems associated with nuclear technology remain unsolved and seem, for the time being, unsolvable. Technology can all but eliminate the risk of nuclear meltdowns, but the associated risks are intrinsic to the technology itself and only increase with the passage of time. It is up to us to decide if clean energy is worth a fully nuclear planet — if we are willing to trade energy for the chance that a terrorist flies a plane into a reactor or contaminates an entire city with a radioactive bomb. But once this technology spreads, there will be no reigning it in.
