Court rejects residents’ call to halt Ehime Prefecture nuclear reactor via Japan Times

HIROSHIMA – The Hiroshima High Court on Friday rejected local residents’ call to halt the operation of an idled nuclear reactor in western Japan, upholding a lower court decision.

The ruling will allow the operator, Shikoku Electric Power, to continue utilizing the No. 3 reactor at the Ikata nuclear power plant in Ehime Prefecture, which has been suspended for a regular inspection through June 19.

The appeal was filed by seven residents of Hiroshima and Ehime prefectures who live between 60 and 130 kilometers from the reactor.

The main focal point of the trial was whether the estimate of seismic ground motion, a key factor in a reactor’s quake-resistance design, made by the utility was appropriate.

During court hearings, the residents said the operator’s estimate was inadequate, arguing that a major accident could occur in the event of a powerful earthquake similar to one that devastated northeastern Japan in March 2011.


In November 2021, the Hiroshima District Court dismissed a request by the residents to suspend the reactor, saying that merely citing the magnitude of earthquakes measured across the country does not indicate a similar earthquake will hit the area.

What is the uranium-based ammunition the UK is sending to Ukraine? via PBS News Hour

By Tara Copp, Associated Press


Depleted uranium is a byproduct of the uranium enrichment process needed to create nuclear weapons. The rounds retain some radioactive properties, but they can’t generate a nuclear reaction like a nuclear weapon would, RAND nuclear expert and policy researcher Edward Geist said.


“It’s so dense and it’s got so much momentum that it just keeps going through the armor — and it heats it up so much that it catches on fire,” Geist said.

When fired, a depleted uranium munition becomes “essentially an exotic metal dart fired at an extraordinarily high speed,” RAND senior defense analyst Scott Boston said.

In the 1970s, the U.S. Army began making armor-piercing rounds with depleted uranium and has since added it to composite tank armor to strengthen it. It also has added depleted uranium to the munitions fired by the Air Force’s A-10 close air support attack plane, known as the tank killer. The U.S. military is still developing depleted uranium munitions, notably the M829A4 armor-piercing round for the M1A2 Abrams main battle tank, Boston said.



While depleted uranium munitions are not considered nuclear weapons, their emission of low levels of radiation has led the U.N. nuclear watchdog to urge caution when handling and warn of the possible dangers of exposure.

The handling of such ammunition “should be kept to a minimum and protective apparel (gloves) should be worn,” the International Atomic Energy Agency cautions, adding that “a public information campaign may, therefore, be required to ensure that people avoid handling the projectiles.

“This should form part of any risk assessment and such precautions should depend on the scope and number of ammunitions used in an area.”

The IAEA notes that depleted uranium is mainly a toxic chemical, as opposed to a radiation hazard. Particles in aerosols can be inhaled or ingested, and while most would be excreted again, some can enter the blood stream and cause kidney damage.

“High concentrations in the kidney can cause damage and, in extreme cases, renal failure,” the IAEA says.

The low-level radioactivity of a depleted uranium round “is a bug, not a feature” of the munition, Geist said, and if the U.S. military could find another material with the same density but without the radioactivity it would likely use that instead.

Depleted uranium munitions were used in the 1991 Gulf War against Iraq’s T-72 tanks and again in the invasion of the country in 2003, as well as in Serbia and in Kosovo. U.S. military veterans of those conflicts have questioned whether their use led to ailments they now face.

Vyacheslav Volodin, the speaker of the Russian parliament’s lower house, said supplies of rounds containing depleted uranium could lead to “a tragedy on a global scale that will primarily affect European countries.”

Volodin said the use of such U.S. ammunition in the former Yugoslavia and Iraq led to “radioactive contamination and a sharp rise in oncological diseases.”

Britain defends supplying Ukraine with weapons containing depleted uranium via the New York Times

Britain on Wednesday defended its decision to supply Ukraine with weapons made with depleted uranium, a day after President Vladimir V. Putin of Russia falsely claimed the material had a “nuclear component.”

Britain’s government has confirmed that it would provide Ukraine with armor-piercing shells that contain depleted uranium, alongside its Challenger 2 tanks, which use them. Depleted uranium is a standard component in conventional anti-armor weapons that NATO countries have used for decades, and Britain said in a statement that the ammunition it was providing had nothing to do with nuclear weapons.

The density of depleted uranium makes it an effective material for piercing heavy armor on the battlefield, and is used by many militaries. Among them are Russia’s, which upgraded its main battle tank to add the ability to fire depleted uranium shells, the Tass state news agency reported in 2018.


Uranium, a heavy metal, must be enriched to be used for nuclear purposes. Depleted uranium, which is about two and a half times denser than steel, is a byproduct of that enrichment, still radioactive but at a much lower level.


The Pentagon has also deemed depleted uranium safe, though after the U.S. military used it in Iraq, some activists and others connected it to birth defects and cancers. Numerous studies have been conducted on a possible link, without firm conclusions.

In 2013, Britain’s Ministry of Defense downplayed any health or environmental risks related to the use of depleted uranium. In a paper, it said that while the dust released on impact can sometimes be a health hazard, “all the research to date indicates that these circumstances are extremely unlikely to occur, and, if they do, will only affect very small groups who will be at much greater risk from the other hazards associated with armed conflict.”

A Nuclear Plant That Leaked 400,000 Gallons of Radioactive Water Will Be Shut Down After Second Incident via NBC News

Erik Ortiz/NBC News

The owner of one of Minnesota’s two nuclear power plants said it will temporarily power down the facility Friday to repair a recurring leak of radioactive water discovered this week, occurring as state regulators had been monitoring the effects of an initial spill four months ago.

While Xcel Energy said in a news release Thursday that there is “no risk to the public or the environment” with the latest incident at the Monticello Nuclear Generating Plant, the city said it would test the municipal water supply out of precaution.


But some Monticello residents surrounding the plant — located 38 miles northwest of Minneapolis and upstream of the Mississippi River — say they have concerns about what a recurring leak presents and the delay in finding out about the initial spill.

“I think the general public needs to be informed more about this,” said Megan Sanborn, 31, who lives 6 miles upstream from the nuclear plant.

“My children go to school 2 miles downstream from the power plant,” she added. “If the water levels were safe the entire time like they were saying, then where was the transparency?”


In late February, the city was informed about the leak. But it wasn’t until March 16 when state officials told the public and Xcel Energy announced it had been taking steps to contain and manage the leak over the past four months.

“After the company told the state, it was a hush-hush situation,” Sanborn said. “No one from the state let residents know we had a nuclear leak, and when we don’t have the ability to overcome a potential impact because no one told us, that’s a big concern for residents.”

A Nuclear Power Plant Leaked Contaminated Water in Minnesota. Here’s What We Know via NPR

Minnesota officials are monitoring the cleanup of a 400,000 gallon leak of contaminated water from a nuclear power plant in the city of Monticello run by the energy giant Xcel Energy. Officials said there is no danger from the leak.

The leak was detected nearly four months ago and reported to state and federal regulators. The federal Nuclear Regulatory Commission posted a notice publicly at the time, but the company and state agencies did not notify the general public until last week.

“Xcel Energy took swift action to contain the leak to the plant site, which poses no health and safety risk to the local community or the environment,” the company announced in a statement on Thursday. Ongoing monitoring has confirmed that the leak “is fully contained on-site and has not been detected beyond the facility or in any local drinking water,” the company said.

Xcel confirmed the leak of water containing tritium in November 2022 and notified officials the same day, according to the company’s announcement. Officials attributed the leak to a water pipe running between two buildings at the plant site. The amount of contaminated water that leaked out is enough to fill an Olympic-sized swimming pool about 60% full.


“Many operating nuclear plants have had some level of tritium leakage at some point during their operations,” Nygard said.

Michael Rafferty, a spokesperson for the Minnesota Pollution Control Agency, told NPR the agency waited to get more information before announcing it to the public.

“Minnesota state agencies are deeply committed to our role in protecting human health and the environment and take seriously our responsibility to promptly inform the public when a situation presents any sort of current or imminent risk,” Rafferty said. “The situation at Xcel Energy’s Monticello site did not — and still does not — present an imminent threat to residents’ health.”

Officials with the federal Nuclear Regulatory Commission did not immediately respond to requests for comment. A spokesperson for the NRC, Victoria Mitlyng, told a local news station that the public’s concern was “very understandable,” and emphasized that “the public in Minnesota, the people, the community near the plant, was not and is not in danger.”

What is tritium?

Tritium is a naturally occurring form of hydrogen that emits a weak form of radiation, which can’t travel far in air or penetrate skin, according to the NRC.

Tritium is also a byproduct of producing electricity in nuclear power plants, and the dose of tritium that comes from nuclear power plants is much lower than exposures from radiation present in the natural environment, according to the NRC. Xcel said the tritium levels in the leaked water were below NRC safety thresholds.

“Everyone is exposed to small amounts of tritium every day, because it occurs naturally in the environment and the foods we eat,” according to an NRC fact sheet.

Any radiation exposure can pose some health risk, including increased occurrence of cancer. The risks of exposure are linear, meaning lower levels of radiation pose lower risk.

Eating or drinking food or water with tritium in it is the most common way it enters the body. It can also be absorbed through the skin. About half of it leaves the body within 10 days after exposure.

The cleanup will take months

Xcel says it has recovered about 25% of the tritium-contaminated water that leaked, and recovery efforts will continue over the course of the next year.

“While this leak does not pose a risk to the public or the environment, we take this very seriously and are working to safely address the situation,” Chris Clark, president of Xcel Energy–Minnesota, North Dakota and South Dakota, said in the company’s statement. “We continue to gather and treat all potentially affected water while regularly monitoring nearby groundwater sources.”

To contain the leak, the water is being diverted to a treatment system inside the plant, which prevents water from leaving the plant. Xcel said it also inspected all of its piping to ensure this wasn’t also happening elsewhere in the facility.

The Minnesota Pollution Control Agency said Xcel is considering building above ground storage tanks or installing a retention pond to store the water containing tritium that has been recovered, as well as considering treatment, reuse and disposal options. Minnesota regulators will review any options the company selects, MPCA said.

“Our top priority is protecting residents and the environment, and the MPCA is working closely with other state agencies to oversee Xcel Energy’s monitoring data and cleanup activities,” said Kirk Koudelka, MPCA assistant commissioner for land and strategic initiatives. “We are working to ensure this cleanup is concluded as thoroughly as possible with minimal or no risk to drinking water supplies.”

Zaporizhzhia Nuclear Plant Disconnected via Aljazeera

After another blackout at the Zaporizhzhia Nuclear Power Plant (ZNPP) in Ukraine, the head of the United Nations nuclear watchdog has appealed for a protection zone, saying he was “astonished by the complacency” of the organisation he leads, the International Atomic Energy Agency (IAEA).

Russian forces pounded several Ukrainian cities while people slept on Thursday, killing at least six civilians, knocking out electricity, and forcing Europe’s largest nuclear plant off the grid for a sixth time since Moscow’s invasion began last year.

The last time all power was lost at the site was on November 23, 2022, Rafael Grossi told the IAEA board of directors in a meeting on Thursday.

“What are we doing to prevent this [from] happening? We are the IAEA, we are meant to care about nuclear safety,” he said.

“Each time we are rolling a dice. And if we allow this to continue time after time then one day our luck will run out.”


Grossi has long tried to get both sides to strike a deal, pledging they would not fire at or from the plant and heavy weapons would be removed.


In his statement to the IAEA board, Grossi stressed: “This is the sixth time – let me say it again sixth time – that ZNPP has lost all off-site power and has had to operate in this emergency mode. Let me remind you – this is the largest nuclear power station in Europe. What are we doing? How can we sit here in this room this morning and allow this to happen? This cannot go on.”
