Anger as Hinkley Point C allowed to discharge sewage into Bristol Channel and drop fish protection
AN Exmoor parish council chairman is demanding
the Environment Agency explain why it has dropped a requirement for Hinkley
Point C nuclear power station to use acoustic fish deterrents (AFDs) in its
water intakes in the Bristol Channel.
Anti-nuclear campaigners fear 11 billion fish could be killed during the 60-year lifetime of the £27 billion power station if AFDs were not used. The Environment Agency has confirmed
it has agreed to applications to vary licences for NNB Generation Company
(HPC) Ltd, the vehicle through which EDF is building the power plant. But
the decision has been criticised by Katherine Attwater, who chairs
Timberscombe Parish Council, is a member of the campaign group Stop
Hinkley.

Agency to test for tritium in fish after Fukushima water discharge
The Fisheries Agency will conduct daily checks of tritium levels in fish
caught off the coast of Fukushima Prefecture after treated water from the
Fukushima No. 1 nuclear power plant is released into the ocean.
The agency announced on Aug. 10 that the results of the checks would be released two
days later. The study will continue for about a month after the start of
the discharge of water treated after being contaminated with radiation
within the plant grounds.
The government plans to begin releasing the
water, which has accumulated at the crippled plant for more than a decade
and is nearing the capacity of storage tanks on the site, later this
summer. China has been especially virulent in opposing the discharge of the
treated water due to environmental concerns. The results of the daily
checks will be released in Japanese and English by the Fisheries Agency.

Chinese UN mission releases working paper on Fukushima nuclear-contaminated wastewater issue, urging Japan to discharge in responsible manner
By Global TimesP Aug 09, 2023 https://www.globaltimes.cn/page/202308/1295954.shtml
Chinese UN mission releases working paper on Fukushima nuclear-contaminated wastewater issue, urging Japan to discharge in responsible manner
China’s Permanent Mission to the United Nations (UN) and Other International Organizations in Vienna has submitted the working paper on the disposal of nuclear-contaminated water of Japan’s Fukushima Daiichi Nuclear Power Station to the First Preparatory Committee for the Eleventh Review Conference of the Treaty on the Non-Proliferation of Nuclear Weapons (NPT).
The disposal of nuclear-contaminated water from Fukushima concerns the global marine environment and public health. There is no precedent for artificially discharging nuclear-contaminated water into the ocean and no internationally recognized disposal standards.
The international community should attach great importance to Japan’s ocean discharge of the nuclear-contaminated water and urge Japan to dispose of the contaminated water in a responsible manner, according to the working paper released on Wednesday.
The working paper pointed out that Japan had previously discussed five ways to dispose of the contaminated water, namely injection into the ground, discharge into the ocean, vapor release, release as hydrogen gas into the atmosphere, and underground burial. However, Japan did not conduct a thorough study of all disposal options and insisted on choosing ocean dumping, which was the lowest cost option, thus transferring the risk of nuclear contamination.
If the so-called ”treated-water” is really safe and harmless, why does Japan not dispose of it within its own territory or use it for industrial and agricultural purposes? The working paper pointed out.
The paper noted that Japan fails to prove the long-term effectiveness and reliability of the purification equipment for treating the contaminated water. According to the data released by Japan, nearly 70 percent of the nuclear-contaminated water treated by Japan’s ALPS (Advanced Liquid Processing System) still fails to meet the discharge standard and needs to be purified again.
Japan has failed to prove the authenticity and accuracy of the data on contaminated water. Fukushima power plant operator TEPCO has repeatedly concealed and falsified nuclear-contaminated water related data in recent years. The IAEA conducted its review and assessment solely based on the data and information provided by Japan, and carried out inter-laboratory comparative analyses of only a small number of nuclear-contaminated water samples collected by Japanese officials, read the working paper.
According to general international law and the provisions of UN Convention on the Law of the Sea, Japan has the obligation to protect and preserve the marine environment. The Convention on the Prevention of Marine Pollution by Dumping of Wastes and Other Matter 1972 (the London Convention) prohibits the dumping of radioactive waste into the sea by means of man-made structures at sea. Japan’s discharging of nuclear-contaminated water into the sea by means of submarine pipelines is in violation of the relevant provisions of the London Convention.
Japan has failed to demonstrate the perfection of the monitoring program. Tokyo must not start discharging until the long-term monitoring mechanism is established, and must stop discharging water once anomalies are detected in the data on the discharge of nuclear contaminated water.
The Chinese UN mission stressed that Japan should not confuse the concept of nuclear-contaminated wastewater with the wastewater from the normal operation of nuclear power plants.
The working paper warned Japan of not making use of IAEA’s comprehensive assessment report on the disposal of Fukushima nuclear-contaminated water as ”shield” or ”greenlight” for the dumping plan.
In addition, the paper urged Japan to fully respond to the concerns of China and the international community, and dispose of the nuclear-contaminated water in a responsible manner in line with its obligations under international law, stop pushing through the dumping plan, fully consult with stakeholders including neighboring countries, make sure to handle the nuclear contaminated water in a science-based, safe and transparent way, and subject itself to rigorous international oversight
Fish Hell – impacts of sea water nuclear cooling systems
12 July 2023 https://www.banng.info/news/regional-life/fish-hell/
Varrie Blowers looks at the devastating impacts of sea water cooling systems on the marine environment in the July 2023 edition of Regional Life
What amounts to a ‘fish hell’ is being proposed at the Hinkley Point C (HPC) new nuclear power station. This provides an indication of what might happen on the Blackwater if a new nuclear station or so-called Small Modular Reactors were ever built here.
In 2019, conservation groups predicted that the gigantic twin cooling water intake tunnels at HPC would kill up to 250,000 fish a day. Eels, small fish and the fry of many species, such as salmon, whiting and cod, and microorganisms will be sucked into the cooling system through the 5mm mesh installed to prevent larger fish being swallowed up into this fish hell, to be discharged in heated water after hideous suffering. If this seems outrageous, things may be about to get worse.
To gain Planning Permission HPC’s developer, Electricité de France (EDF), was required to instal Acoustic Fish Deterrents (AFDs) in the intake pipes to give some warning to fish to keep away. EDF does not now want to instal these, most likely for financial reasons. Without AFDs, Stop Hinkley! argues that up to 500,000 fish a day will be sucked into the cooling water intakes. That suggests 11 billion fish and other marine life will be destroyed in the c.60 years life of the station.
Conditions may be different in the Bradwell B context but any nuclear development that requires cooling water from the estuary would severely affect marine life. Affected, too, would be the many wildfowl and migratory birds that depend on fish and other marine life for food in estuaries like the Severn and Blackwater, which support important and protected habitats.
In other sobering news, an ‘unheard of’ heatwave in our coastal waters has been reported. Before you jump into the sea, consider the impacts of warmer water on our marine life. If the heatwave continues through the summer, experts believe ‘we could see the mass mortality of kelp, seagrass, fish and oysters’ (Guardian, 20 June).
Do right by the whales
Beyond Nuclear International 6 Aug 23
No environmental study has ever been conducted of the impact of the North Atlantic right whales’ protected birthing waters being occupied by the massive Kings Bay naval station
Nuclear sub base expansion ignores precious species; missiles could destroy us all
Background: The U.S. Navy has released a Draft Environmental Assessment for the homeporting of the Columbia Class submarines at Naval Submarine Base (NSB) Kings Bay.
The Navy proposes to establish facilities and functions at NSB Kings Bay to support the homeporting of Columbia Class submarines as replacements for the retiring Ohio Class submarines currently homeported at NSB Kings Bay. Under the Proposed Action, the Navy would construct eight facilities, modify five facilities, and demolish three facilities across three locations on NSB Kings Bay.
Facility changes and development activities would be phased over a period of five years and completed coincident to the first Columbia Class submarines in 2028.
Nuclear Watch South has prepared comments opposing this development. The following article is drawn from their statement and comments recently submitted to the U.S. Navy.
Georgia’s 100 miles of Atlantic Ocean coastline is a globally unique, fertile, and fragile marshland environment of barrier islands, freshwater tidal forests, maritime forests, and endangered longleaf pine forest. Georgia’s vast salt marshes support a staggering diversity of plant and animal life nurturing the eggs and hatchlings of countless sea creatures and providing significant nesting and migration habitat for 200 bird species.
Kings Bay, near the Georgia-Florida state line, is home base for six Trident submarines and deploys 25% of the U.S. nuclear arsenal. A Trident submarine is the most expensive and deadly nuclear weapons system on Earth. The only other nation to possess a similarly powerful system is the United Kingdom, a longtime United States ally. The Trident has been controversial since its inception as it upsets the so-called MAD (Mutually Assured Destruction) power balance, fueling a dangerous and costly international arms race.
The Navy conducted an Environmental Impact Statement (EIS) in 1977 when Kings Bay Naval Submarine Base was first proposed. The EIS was performed to fulfill environmental and public accountability requirements of the newly instituted National Environmental Protection Act (NEPA) of 1969.
In 1979, construction began on Kings Bay. In 1984, it was first discovered that the base had unwittingly intruded upon the (previously unknown and apparently only) birthing waters for the critically endangered North Atlantic right whales in the Cumberland Sound.
Kings Bay base began operations in 1989. The Soviet Union dissolved in 1991. At the same time, the U.S. nuclear weapons manufacturing complex, occupying vast reservations in more than a dozen states from Washington to South Carolina, was shuttering its reactors and facilities amidst revelations of widespread nuclear contamination and vast inventories of poorly managed radioactive wastes.
The nuclear weapons complex suddenly and belatedly became subject to environmental law and NEPA has since proved to be a difficult filter through which to permit new nuclear weapons manufacture.
For example, the U.S. Department of Energy and National Nuclear Security Agency have failed in five attempts over the past 30 years to establish a plutonium pit production facility at the Savannah River Site (SRS) on the South Carolina/Georgia state line.
Nuclear weapons manufacturing has languished since 1990 in all nuclear-armed nations and limited nuclear treaties have greatly reduced nuclear stockpiles. All nuclear testing ceased in 1992. Trident submarines now carry fewer nuclear weapons, but each Trident submarine currently can deploy the explosive power of 1,825 Hiroshimas.
In 2021, the UN Treaty on the Prohibition of Nuclear Weapons entered into force, presently counting 68 nations as parties. The treaty begins by expressing the parties’ concern for “the catastrophic humanitarian consequences that would result from any use of nuclear weapons, and recognizing the consequent need to completely eliminate such weapons, which remains the only way to guarantee that nuclear weapons are never used again under any circumstances.”
This landmark, game-changing treaty sets forth as international law that it is illegal to “develop, test, produce, manufacture, otherwise acquire, possess or stockpile nuclear weapons or other nuclear explosive devices.”
The North Atlantic right whale population rebounded from near extinction when hunting the whales was outlawed in 1935. The whales encountered new hazards, however, with the industrialization of shipping and fishing. Ship strikes and entanglement in fishing gear are held responsible for mortality events which are now decimating the whale population.
The current population of the critically endangered North Atlantic right whale has crashed to fewer than 350 animals. The National Oceanic and Atmospheric Administration (NOAA) estimates 50 births per year are required to avoid extinction of these ancient, magnificent marine mammals. In 2022, only 15 North Atlantic right whales were born.
No environmental study has ever been conducted of the impact of the North Atlantic right whales’ protected birthing waters being occupied by the massive Kings Bay naval station.
Despite the moribund state of nuclear weapons manufacture, in 2022, the U.S. spent $83,000 per minute on nuclear weapons. This budget includes items such as the redundant Columbia class submarine, which this environmental study narrowly contemplates.
Earth’s inhabitants now face extreme dislocation from climate change in addition to living under the Damocles sword of nuclear annihilation for the previous three generations. Clearly, resources now squandered on nuclear weapons can be converted to the task of making the lifestyle changes required to retain our planet’s life-supporting atmosphere.
It is the pleasure and duty of the public to participate in important decisions as framed and codified by the National Environmental Policy Act of 1969. Nuclear Watch South lists here the pertinent portions of the Act upon which these comments rely.
Comments
An Environmental Assessment is inadequate. An Environmental Impact Statement should be performed…………………………………………………………………………….
Before 1984, it was unknown where the critically endangered North Atlantic right whales gave birth to their calves. Nuclear Watch South believes that the construction activities of the naval base forced the whales into open waters during a most vulnerable part of their life cycle, which led to the death of the baby calf discovered in 1982 and puts ongoing pressure upon the dwindling population of this critically endangered, protected species. Kings Bay’s presence must be counted among the human-created hazards driving the North Atlantic right whale to extinction.
The reasonably foreseeable impact of nuclear weapons is wholesale environmental destruction
NEPA requires analysis of all foreseeable impacts from the proposed activity. The environmental impact from use of the nuclear weapons and nuclear weapons system housed at Kings Bay must be contemplated in an EIS. It is the nature of the SSBN (Sub-Surface Ballistic Nuclear) program that it is capable of destroying the whole Earth. The whole Earth is stakeholder…………………………………………………
Kings Bay impacts on unique Georgia coastal environment are absent from EA and must be considered in an EIS
Kings Bay is a complex and unique site with environmental impacts from 30 years of Kings Bay operation in the sensitive Georgia coastal eco-system. Kings Bay’s previous environmental impacts, some of which are highlighted below, must be included in an EIS……………………………………………………………….
The sound where whales have given birth for previous millennia is regularly dredged to accommodate the five-story Trident submarines. In addition, U.S. Navy sonar testing has been shown to harm sea turtles and marine life, including the large marine mammals, whales, and dolphins. The impacts of Kings Bay on the dwindling North Atlantic right whale population’s southern range must be considered in addition to its impacts on other sea-life……………………………………………………………..
We are at a cultural crossroads that requires contemplation of whether to continue planet-killing nuclear arms roulette or to denuclearize and end the Atomic Age to avert annihilation. The NEPA process provides for a public and transparent exploration of the “big picture” with respect to large projects. Indeed, NEPA was borne out of the previously unforeseen environmental misadventures of the military industrial complex and instituted as a method to avert disaster with experience and deep foresight.
An alternative to continued “business as usual” at Kings Bay would be to remove the submarine killing machines and nuclear weapons from this sensitive, fragile, and vital eco-system and instead maintain a presence of national defense in the coastal marsh with a Coast Guard base and marine wildlife sanctuary.
This serves as a more benign project for our national defense that will also defend our wildlife and restore a healthy atmosphere to our planet.

Failed Fukushima System Should Cancel Wastewater Ocean Dumping

The global ban on ocean dumping of radioactive waste adopted in 1993 applies only to barrels. It has allowed Britain and France to pump billions of gallons of radioactive wastewater into the Irish Sea and the North Sea respectively, for decades.
BY JOHN LAFORGE, 25 July 23 https://www.counterpunch.org/2023/07/25/failed-fukushima-system-should-cancel-wastewater-ocean-dumping/
From the Fukushima-Daiichi triple-reactor meltdown wreckage, Japan’s government and “Tepco,” the owner, are rushing plans to pump 1.37 million tons (about 3 billion pounds) of radioactive wastewater into the Pacific.
Their record is poor. Their lies are documented. This is not safe, at all.
To keep the three meltdowns’ wasted fuel from melting again, Tepco continuously pours cold water over 880 tons of “corium,” the red-hot rubblized fuel amassed somewhere under three devastated reactors. “That water leaks into a maze of basements and trenches beneath the reactors and mixes with groundwater flowing into the complex,” Reuters reported Sep. 3, 2013.
Most of this water is collected and put through Tepco’s jerry-rigged mechanism dubbed ALPS, for Advanced Liquid Processing System, which it turns out hasn’t processed much of anything.
Tepco, Japan’s Nuclear Regulatory Authority, the International Atomic Energy Agency (IAEA), and much of the media endlessly repeat that ALPS removes over 62 radioactive materials from the ever-expanding volume of wastewater. Reports regularly claim the planned dumping is routine, safe, and manageable.
This unverified PR loop has fooled a lot of people, but the ALPS is a fraud. As early as 2013, the filter system stalled and the IAEA reported that April that ALPS had not “accomplished the expected result of removing some radionuclides,” Reuters reported.
In September 2018, the ALPS was revealed to have drastically failed, forcing Tepco to issue a public apology and a promise to re-filter huge volumes of the waste.
According to Reuters, Oct. 11, 2018, documents on a government committee’s website show that 84 percent of water held at Fukushima contains concentrations of radioactive materials higher than legal limits allow to be dumped.
Among the deadly isotopes still in the waste are cesium-137, strontium-90, cobalt-60, ruthenium, carbon-14, tritium, iodine-129, plutonium isotopes, and more than 54 more.
In a June 14, 2023 op/ed for the China Daily, Shaun Burnie, the Senior Nuclear Specialist at Greenpeace East Asia, reported that the ALPS “has been a spectacular failure,” and noted:
“About 70 percent or 931,600 cubic meters of the wastewater needs to be processed again (and probably many more times) by the ALPS to bring the radioactive concentration levels below the regulatory limit for discharge. Tepco has succeeded in reducing the concentration levels of strontium, iodine, and plutonium in only 0.2 percent of the total volume of the wastewater, and it still requires further processing. But no secondary processing has taken place in the past nearly three years. Neither Tepco nor the Japanese government has said how many times the wastewater needs to be processed, how long it will take to do so, or whether the efforts will ever be successful. … none of these issues has been resolved.”
Tepco says it will re-filter more than 70 percent of the wastewater through ALPS again, a process that itself leaves massive amounts of highly radioactive sludge that must be kept out of the environment for centuries.
Hoping to slow the rush to dump, Professor Ryota Koyama from Fukushima University, said in an interview with China Media Group last May, “If the Japanese government or the Tokyo Electric Power Co. really wants to discharge contaminated water into the sea, they need to explain in more detail whether the nuclides have really been removed.”
International law governing state-sponsored or corporate pollution of the seven seas is relatively useless in challenging Tepco’s outrageous transfer of private industrial poison into the public commons. The global ban on ocean dumping of radioactive waste adopted in 1993 applies only to barrels. It has allowed Britain and France to pump billions of gallons of radioactive wastewater into the Irish Sea and the North Sea respectively, for decades.
Cesium 180 times limit found in fish at Fukushima nuke plant 12 years after disaster.

July 19, 2023 (Mainichi Japan)
FUKUSHIMA — Radioactive cesium 180 times Japan’s legal maximum has been found in fish caught in the port at the crippled Fukushima Daiichi nuclear plant, revealing that the March 2011 triple meltdown there continues to impact the local ecosystem.
The cesium in the black rockfish caught in May measured 18,000 becquerels per kilogram. The legal limit under the Food Sanitation Act is 100 becquerels per kg. According to plant operator Tokyo Electric Power Company (TEPCO) Holdings Inc., the fish was captured inside the inner breakwater, close to the No. 1 to No. 4 reactors at the seaside plant, where decommissioning work continues.
When it rains, the rainwater streams into the “K drainage” — one of several drainpipes at the plant — after running through debris and over the ground, both contaminated with radioactive substances. It is then discharged into the station’s small port.
TEPCO claims that it has confirmed the cesium levels in the discharged rainwater are below the government criteria of 60 becquerels per liter for cesium-134 and 90 becquerels for cesium-137. But compared with other drainages at the plant, runoff with higher concentrations of radioactive materials has been discharged within the inner breakwater. The seabed sediment in the area was also found to contain cesium-137 up to 130,000 becquerels-plus per kilogram and cesium-134 up to 3,400 becquerels-plus as of the end of January this year………………………………………………………………..
……………………………………………………….”We urge that TEPCO take thorough measures to prevent radioactive materials from getting into the ocean, even within the port,” a fisheries federation official urged, refering to the black rockfish with more than 100 becquerels per kg caught in May at the nuclear complex’s port.
Toshihiro Wada, an associate professor of fish ecology at Fukushima University, said of the heavily contaminated fish, “It’s likely that cesium was concentrated within the fish from the food chain, confined as it is by the inner breakwater where radioactive substances have accumulated from the drainages flowing into the port.”
He continued, “Unless fundamental measures are taken to lower the concentrations of radioactive materials discharged from the ‘K drainage,’ fish surpassing the maximum will likely keep being found,” even as TEPCO has stepped up measures to prevent fish from getting away…………………………………
Radioactively contaminated water has been swelling daily at the plant as water injected to cool nuclear fuel debris that melted down in the 2011 disaster has been accumulating with groundwater and rainwater mixing into it. TEPCO processes the contaminated water using ALPS, or multi-nuclide removal equipment, and stores the treated water in tanks after reducing the radioactive levels apart from tritium, which is difficult to remove from water.
‘Set treated water aside’
The Japanese government plans to release treated water from the Fukushima plant into the ocean around the summer, after diluting it to get tritium concentrations below 1,500 becquerels per liter, or one-fortieth of the national standard. It plans to release the water about 1 kilometer offshore via an undersea tunnel.
“Unlike cesium, tritium does not concentrate in fish even if they ingest it, according to data,” associate professor Wada said. “Experimental results have shown that if treated water is put into regular seawater, the concentration (of tritium) is reduced. We need to consider (tritium) separately from cesium.”

To the Pacific islands, the West’s support for Japan’s Fukushima nuclear waste ocean dumping is hypocrisy
Having been used for nuclear tests and dumping by the US and France, the Pacific islands deeply oppose Japan’s plan and see it as a ‘nuclear legacy’ issueThat the likes of Australia and the US support Japan’s plan just ups the region’s geopolitical stakes – and gives China a trump card
Kalinga Seneviratne, SCMP, 18 Jul 23
International Atomic Energy Agency (IAEA) director general Rafael Mariano Grossi, after travelling to Tokyo earlier this month to present a report endorsing Japan’s approach to discharging Fukushima’s treated nuclear waste water into the Pacific, has been trying to convince Japan’s sceptical Pacific neighbours of the authenticity of the report’s findings.
The IAEA, which has opened the door for Tokyo Electric Power Company (Tepco) to dump about 1.3 million tonnes of contaminated water into the Pacific Ocean, insists the controlled, gradual release would have a “negligible radiological impact on people and the environment”.
But the small island nations of the Pacific remain deeply concerned about Japan’s intention to dump nuclear waste into the ocean. They see this as not merely a nuclear safety issue but a “nuclear legacy issue” – the Pacific has been used as a nuclear weapon testing and dumping site since the end of the second world war………………….(Subscribers only) more https://www.scmp.com/comment/opinion/article/3228154/pacific-islands-wests-support-japans-fukushima-nuclear-waste-ocean-dumping-hypocrisy
Biodiversity loss
There is widespread agreement that climate change is an existential
threat. But in our rush to address this challenge, our efforts must not
heighten another, more immediate one: the global decline of biodiversity.
We are losing species at more than 1,000 times the natural rate. If we stay
on this trajectory, we risk losing up to half of them by the middle of the
century. Science is only just beginning to quantify the magnitude of
throwing a complex system like Mother Nature out of balance. But we do know
that biodiversity loss poses a fundamental risk to health, prosperity and
wellbeing. Sadly, the singular focus on solving climate change has led to
the neglect of biodiversity. The alarming result is that many climate
efforts inadvertently accelerate nature’s destruction. Take the huge need
for solar farms. If not located properly, they will have a big impact on
ecosystems and habitats.

Japan to Release 1.3 Million Tonnes of Water Used During Fukushima Nuclear Accident
The water used to cool damaged reactor cores from the Fukushima Daiichi Nuclear Power Plant accident in March 2011.
David Krofcheck, The Wire 16 Jul 23
“…………………………………………This year the Japanese government plans to release 1.3 million tonnes of water – used to cool the damaged reactor cores from the Fukushima Daiichi Nuclear Power Plant accident in March 2011 – into the Pacific Ocean
Between 2011-2013, approximately 300,000 tonnes of untreated wastewater had already flowed into the ocean off Fukushima. These first two years were the most dangerous time because long-lived heavy nuclei, like cesium-137, strontium-90 and shorter-lived iodine-131, from nuclear fission in the reactors ended up in the ocean.
Since 2013, the stored water has also accumulated flushed seawater goundwater which leaked into the three damaged reactor cores.
The big challenge is how to manage 1.3 million tonnes of unsafe radioactively-tainted water………………………………………………………………………….
“As Low As Reasonably Achievable” or ALARA – filtering out the nuclear fission nuclei from the stored wastewater may be the best that can be done. The ALARA approach to reduce nuclear fission nuclei released resulted in a 2013 effort to develop and employ an advanced liquid processing system, or ALPS. A series of filters was designed to remove 62 fission nuclei leaving both tritium and carbon-14 in the water. It only partially worked.
Potentially, this water could be run through more cycles of the ALPS before extra dilution and later release into the ocean.
The other 30% of treated water could also be diluted with seawater by factors of several hundred to one thousand and then released into the ocean. Any remaining tritium from the Fukushima reactor may find its way into the food chain as organically bound tritium via build-up in underwater plants and organisms.
The second option for managing the Fukushima water was to hold it on site in an ever-increasing number of tanks.
If the water is properly filtered to leave only tritium and carbon-14, then the natural decay of tritium can be used to reduce overall radioactivity. Since the radioactive half-life of tritium is 12.4 years, holding the water in tanks for seven half-lives, about 85 years, would reduce the tritium content to less than 1% of its current value. This option leaves the carbon-14 which would still roughly have the same radioactivity due to its 5,730-year half-life.
However, storing a tremendous volume of water for an entire human lifespan has never been tried. Even more water and storage tanks would need to be added as decommissioning the Fukushima Daiichi nuclear reactor cores proceeds. This is problematic.
A third option was to evaporate the water on land near Fukushima.
A 1979 nuclear accident at Three Mile Island Nuclear Station in the United States resulted in a similar radioactive water storage problem. About 9,300 tonnes of tritiated water, about 140 times less than that currently held in the Fukushima storage tanks, was electrically evaporated over two years. The tritium was released into the atmosphere, resulting in a radiation dose to people in the surrounding area of about one-hundredth of the natural background radiation.
Japan and TEPCO would need to deal with even larger amounts of water and tritium emitted into the atmosphere if the 30-year timeline for the reactor core clean-up is followed……………….. https://thewire.in/environment/japan-to-release-1-3-million-tonnes-of-water-used-during-fukushima-nuclear-accident
SpaceX’s Starlink satellites are leaking electromagnetic radiation that’s ‘photobombing’ our attempts to study the cosmos
Live Science , By Harry Baker 2 Jul 23
New research finds that SpaceX’s Starlink satellites are leaking radiation that could interfere with radio astronomy.
But in the new study, published July 3 in the journal Astronomy & Astrophysics, researchers have shown that Starlink satellites also emit unintended and previously unrecognized radio signals that are separate from the signals they send to and receive from our planet. Some of these signals overlap with those detected by the dishes of radio telescopes — which represents a new problem in this scientific field………………………………………………
SpaceX likely isn’t the only culprit; the researchers expect to detect similar emissions from many other satellites in low Earth orbit (LEO). The problem also could worsen as the number of private satellites in LEO continues to increase dramatically. For example, there were only 2,000 Starlink satellites in LEO when the data was collected, but there are now more than 4,000.
“Our simulations show that the larger the constellation, the more important this effect becomes as the radiation from all satellites adds up,” study co-author Gyula Józsa, an astronomer at the Max Planck Institute for Radio Astronomy in Germany, said in the statement. “This makes us not only worried about the existing constellations, but even more about the planned ones.”…………………
Emitting radio signals is not the only way that satellites can interfere with astronomy. The shiny spacecraft can also reflect light back toward the planet’s surface, which can leave white streaks across time-lapse images. In December 2022, the International Astronomical Union warned that the world’s largest communication satellite, known as BlueWalker 3, is creating interference that could “severely hamper progress in our understanding of the cosmos.” https://www.livescience.com/space/space-exploration/spacexs-starlink-satellites-are-leaking-radiation-thats-photobombing-our-attempts-to-study-the-cosmos
How much water do French nuclear plants use?

Figures showing that the cooling of reactors could capture 30% of water resources have been removed from the site of the Ministry of Environment.
Le Monde ,By Perrine Mouterde, March 26, 2023,
How much do nuclear power plants contribute to total water consumption in France? This simple question no longer seems to have a clear answer. At the root of the confusion lies the Ministry of Environmental Transition’s removal of a background paper on the resourcing and use of water in France on around March 10. According to this fact sheet from the statistical service, power plant cooling represented the second most water-consuming activity in the country (31%), behind agriculture (45%) and ahead of drinking water (21%) and industrial use (4%). The annual volume of water consumed in mainland France, over the period 2008-2018, was estimated at 5.3 billion cubic meters.
In the midst of the review of the parliamentary bill to accelerate the construction of new reactors, the figure of 31% was being used by opponents of atomic energy to demonstrate that this energy source was not adapted to climate change. “Once and for all, let’s say it, simply and firmly: at this rate, there will soon not be enough water in our rivers to cool the nuclear power plants!,” stated Marine Tondelier – the national secretary of Europe Ecologie-Les Verts (EELV, Greens) – on March 7, based on this data.

The site to represent the start of the Anthropocene epoch on Earth has been selected by scientists. It will mark the end of 11,700 years of a stable global environment in which the whole of human civilisation developed and the start of a new age, dominated by human activities.
The site is a sinkhole lake in Canada. It hosts annual sediments showing clear spikes due to the colossal impact of humanity on the planet from 1950 onwards, from plutonium from hydrogen bomb tests to the particles from fossil fuel burning that have showered the globe.
If the site is approved by the scientists who oversee the geological timescale, the official declaration of the Anthropocene as a new geological epoch will come in August 2024.
Experts said the decision has social and political importance, as well as great scientific value, as it would testify to the “scale and severity of the planetary transformation processes unleashed by industrialised humanity”.
The climate crisis is the most prominent impact of the Anthropocene, but huge losses of wildlife, the spread of invasive species, and the widespread pollution of the planet with plastics and nitrates are also key features.
The Anthropocene Working Group was set up in 2009 and in 2016 concluded that the human-caused changes to Earth were so great that a new geological time unit was justified. The AWG then assessed in detail a dozen sites across the world as candidates for what geologists call a “golden spike”, ie the place where the abrupt and global changes marking the start of the new age is best recorded in geological strata.
Candidate sites included tropical corals in the US and Australia, a mountainous peat bog in Poland, the Antarctic ice sheet and even the human debris accumulated under the city of Vienna. However, after several rounds of voting by the AWG, Crawford Lake, near Toronto, was selected.
“There is compelling evidence globally of a massive shift, a tipping point, in the Earth’s system,” said Prof Francine McCarthy, a geologist at Brock University, Canada, and AWG member. “Crawford Lake is so special because it allows us to see at annual resolution the changes in Earth history.
The lake, formed in a limestone sinkhole, is 24 metres deep but only 2.4 hectares in area. That tall shape means the bottom waters and surface waters do not mix, which would confuse the record laid down in the sediments. “The bottom of the lake is completely isolated from the rest of the planet, except for what gently sinks to the bottom and accumulates in sediment,” McCarthy said.
The AWG has chosen the plutonium isotopes from H-bomb tests as the key marker for the Anthropocene, as they were spread globally from 1952 but declined rapidly after the Nuclear Test Ban Treaty in the mid-1960s, creating a spike in sediments.
“The presence of plutonium gives us a stark indicator of when humanity became such a dominant force that it could leave a unique global ‘fingerprint’ on our planet,” said Prof Andrew Cundy, an environmental radiochemist at the University of Southampton, and AWG member.
There are other important markers in the lake sediments, including spherical carbon particles produced by the burning of fossil fuels in power plants and nitrates from the mass application of chemical fertilisers. “We have a dramatic increase in the concentration in our core at exactly the same depth that we see the rapid rise in plutonium,” said McCarthy.
The 1950s saw the start of the “great acceleration”, the unprecedented increase in industrial, transport and economic activity that occurred after the second world war and continues today. “It is the great acceleration that we decided to use as a major tipping point in Earth history. But it is the increase in plutonium 239 fallout specifically that we chose as the marker,” said McCarthy.
Prof Jürgen Renn, director of the Max Planck Institute for the History of Science, in Berlin, Germany, said: “The Anthropocene concept has now received a firm anchoring in a very precise stratigraphic definition, [giving] a reference point for scientific discussions.
“It also creates a bridge between the natural sciences and the humanities, because it’s about the humans,” Renn said. “We are looking at something that is shaping our fate as humanity, so it’s very important to have a common reference point.”
Official ratification of the Crawford Lake site and the Anthropocene epoch requires passing three more votes of geological authorities, the subcommission on Quaternary Stratigraphy, the International Commission on Stratigraphy and finally the International Union of Geological Sciences.
The decision may be a difficult one for geologists, who are used to dealing with time periods spanning millions of years and using rocks with fossils as markers. The AWG will present a dossier of evidence hoping to convince the voting bodies that the Anthropocene does represent a planetary change that requires a new geological time period.
Dr Alexander Farnsworth, at the University of Bristol, said plutonium is a radioactive element and decays over time, so might not persist over geological timescales of millions. He also questioned whether an Anthropocene epoch is needed, saying: “We are but a ripple in the river of gene flow through time.”
Prof Colin Waters, AWG chair from the University of Leicester, said: “The Anthropocene that starts in the 1950s represents a very rapid change that we have caused to the planet. There’s hope in that respect. The combined impacts of humanity can be changed rapidly for good and for bad. It’s not inevitable that we have to slide into continuing environmental poverty
Nuclear bomb fallout marks dawn of new epoch in which humanity dominates planet
Safe or septic – Japan’s nuclear wastewater dumping
RNZ, From The Detail, Tom Kitchin, co-host of The Detail @inkitchnz tom.kitchin@rnz.co.nz 11 July 23
There are diplomatic headaches and heated scientific debates after Japan revealed plans to dump the wastewater it’s been using to cool the Fukushima nuclear power plant – in the Pacific.
…………………………… Sea and ground water has been used to cool the damaged reactors, and now there’s about 1.3 million tonnes of that sitting in tanks while the Japanese government and plant operator Tokyo Electric Power Company (TEPCO) figure out what to do with it.
They want to release the wastewater into the ocean – diluting all the cancer-causing nuclear fission products out of it – such as caesium, which can build up in muscles, strontium-90 which can build up in bones and iodine-129 which can build up in the thyroid.
…………………………………………. journalist Nic Maclellan, a Melbourne-based correspondent with Islands Business Magazine, tells The Detail.
“The Pacific Islands Forum has been especially critical, and appointed an independent scientific panel to investigate safety issues around the proposed dumping,” he says.
“The panel has raised a series of issues around the quality of the sampling, the cost of the sampling, the cost of the programme over decades, the maintenance of safety sampling and the fact that they really don’t know whether Japan can maintain the quality that will stop other radioactive isotopes being released into the ocean.”
There are also questions over whether the wastewater dump is a breach of the Treaty of Rarotonga, signed in 1985, which created a South Pacific nuclear-free zone.
It was largely about nuclear weapons, but article seven talks about preventing nuclear waste dumping.
“Japan has been acting as if these safety concerns are not serious and it’s taken a lot of pressure for Japan to be dragged kicking and screaming into addressing questions, many of which are still unresolved,” Maclellan says.
AUKUS is also a factor now – a security pact between Australia, the United Kingdom and United States. The main news out of that is the US and UK will help Australia get nuclear-powered submarines.
“The nuclear submarines are a breach of the spirit of the Rarotonga treaty. There’s going to be interesting debates about a technical definition of whether this is… a breach of the letter as well as the spirit,” Maclellan says. https://www.rnz.co.nz/programmes/the-detail/story/2018897817/safe-or-septic-japan-s-nuclear-wastewater-dumping
