Leaks at Minnesota Reactor

Events having the potential to affect public health and safety are occurring at Xcel Energy’s Monticello single nuclear power reactor, about 35 miles up the Mississippi River from Minneapolis. Primary cooling water containing tritium (radioactive hydrogen) has been leaking into the ground at least since last November.

Xcel Energy and the Minnesota Department of Health didn’t bother to report the Monticello leak of about 400,000 gallons until mid-March, and then announced, with much fanfare, that there is no risk to public health and safety and that the leak had not reached the Mississippi River. Then, a few days later Xcel Energy announced a second leak of several hundred gallons because the tank into which contaminated water had been collected overflowed. Not bad, for a clown show.

While state and corporate officials say not to worry, the problem is that these same people fail to consider the authority of the National Academy of Sciences in its 2006 report BEIR VII — the Biological Effects of Ionizing Radiation. The book-length BEIR VII conclusively reported that there is no safe dose of ionizing radiation, no level of exposure that can be declared harmless. Every exposure, no matter how small, carries a potential for causing cancers and other mutations.

Considering that the radioactive half-life of tritium is just over 12 years, and that it takes about 10 half-lives before a radioactive substance becomes relatively benign biologically, it is probably premature to speculate about public health and safety impacts. In fact, there are three pathways for leaked radiation to affect the public: it can migrate to the river, which supplies most of the drinking water for Minneapolis; it can migrate into groundwater off-site, where it becomes available for private and municipal water pumps; and it can evaporate. There is no doubt that during the next 120 years, some fraction of the leakage will follow each of these pathways and then affect biological activity. Of course, nobody will ever know how much contamination went where, or know what it did when it got there, because radiation monitoring at Monticello, as well as at the rest of the global commercial nuclear fleet, is mostly incapable of detecting radiation in any of these pathways. It makes better PR to just say there is no threat to public health and safety.

This Monticello pipe leak could be an omen of things to come. The leak occurred because a pipe carrying primary cooling water broke. Primary cooling water circulates through the reactor and thereby becomes radioactive. This radioactivity bombards the pipe through which it flowed with neutrons, and over time, this neutron bombardment causes metals to get brittle. Arguably, the pipe broke because it had become embrittled and something jarred it. The problem here – as with all nuclear reactors — is that every bit of metal at Monticello that is part of the primary system, which contains and controls the nuclear reaction, has also been subjected to this same neutron bombardment. All these metals are at some elevated state of embrittlement, now that the reactor is over 50 years old. As a result, we all now get to sit around and wait to see which components will be next in line to brake, and what the consequences of that breakage will be. That could get real exciting very quickly.

Earth Day ‘23: A Newly Post-Nuclear Germany vs. California’s Reactor Relapse

Germany’s initiative calls out California’s backpedaling

 

By Harvey Wasserman
Reuters reported on December 16, 2022 that renewable sources like these wind turbines now produce over 46% of Germany’s electricity.

This year’s Earth Day marked a massive green energy triumph in Germany that stands in stark contrast to a bitter nuclear challenge in California.

A wide range of estimates puts the two regions at a virtual tie for the world’s fourth and fifth-largest economies.

They also share a leading growth industry — renewable energy — with unprecedented investments in wind, solar, batteries, and efficiency. But when it comes to atomic power, they are headed in very different directions.

On April 15, 2023 Germany claimed a huge global landmark by becoming one of the world’s wealthiest nations to pull the plug on atomic power.

The decision dates back to 2011, when Germany’s powerful Green movement led a national demonstration aiming to shut the seventeen atomic reactors that, at the time, provided around a quarter of the nation’s electricity.

Before the rally took place, four reactor buildings blew up in Fukushima, Japan, sending huge clouds of radioactive fallout into the air and ocean.

Germany’s then-Chancellor Angela Merkel — who has a Ph.D. in quantum chemistry — ordered eight reactors immediately shut, and soon announced a plan to shut the remaining nine by December 31, 2022.

This “energiewende,” or “energy transition,” substitutes wind, solar, battery storage, and increased efficiency for nuclear reactors, moving Germany toward full reliance on renewables. Germany, since then, has invested billions in the renewables sector, transitioning whole towns to locally owned, rooftop solar power and corporate wind power pumped in from large turbines in the North Sea.

The shutdown of Germany’s last three reactors was delayed by nearly four months due to natural gas shortages caused by the Russian war in Ukraine.

It was also complicated by a major atomic breakdown in neighboring France. Heavily reliant on nuclear power, France’s more than fifty standard-design reactors succumbed to a wide range of problems, including generic structural flaws and warming rivers too hot to cool their super-heated radioactive cores. In 2022, with more than half its fleet of reactors under repair, France made up for the energy shortfall by importing power from Germany, much of it generated by the burning of coal.

This prompted the nuclear industry to criticize Germany’s plan by pointing to a rise in the country’s CO2 emissions from burning increased quantities of coal, failing to note that much of that power was being exported to France to compensate for its own shuttered reactors.

California, whose economy may now be slightly larger than Germany’s, has taken an opposite route.

Two of its last four reactors — at San Onofre, between Los Angeles and San Diego — were shuttered in 2012, and closed permanently in 2013, after flaws were found in the turbines and other components.

In 2016, a deal was reached to shut the Golden State’s last two reactors, located at Diablo Canyon, nine miles west of San Luis Obispo. In the 1970s and 1980s, thousands of protestors were arrested at Diablo Canyon, more than at any other American nuclear reactor.

The 2016 shutdown deal involved another energiewende, based on blueprints to replace Diablo’s power with a huge influx of new wind, solar, battery, and efficiency installations. The agreement was approved by the California state legislature, Pacific Gas & Electric (PG&E), the federal Nuclear Regulatory Commission (NRC) and the state Public Utilities Commission. It was signed by then-Governor Jerry Brown, then-Lieutenant-Governor Gavin Newsom, and a wide range of local governments, unions, and environmental groups, all of whom assumed the state would thus be nuke-free once Unit Two was shut in 2025 — the date its original forty-year license would expire.

But along the way, the state experienced two close calls with partial blackouts. During both incidents, Newsom, now the governor, asked consumers to dial back their energy use. Ironically, independent battery capacity — mostly controlled by individual owners — helped the state stay lit.

But Newsom reversed course and now argues that California must keep Diablo open. Infuriating the national safe energy movement, Newsom rammed through the legislature a $1.4 billion midnight bailout for PG&E, to be funded by all of the state’s consumers, including many who live hundreds of miles from the reactors, and receive no energy from it at all.

The Biden Administration also kicked in $1.1 billion, money that safe energy advocates angrily argue would be far better spent on renewables.

In 2019, a statewide petition signed by Hollywood’s Jane Fonda, Martin Sheen, Lily Tomlin, Eric Roberts, and some 2,500 other Californians demanded that Newsom facilitate an independent inspection. Nearing forty years of age, both Diablo reactors suffer a wide range of structural and age-related defects.

They are also surrounded by at least a dozen known earthquake faults, sitting just forty-five miles from the infamous San Andreas fault. Former NRC site inspector Michael Peck, who was stationed at Diablo for five years, has warned it might not survive a major earthquake, for which its owner, PG&E, has little or no private insurance. The state has never made public any plans to evacuate Los Angeles or other heavily populated areas in the event of an accident.

Newsom has also supported moves by state regulators to severely slash compensation paid by utilities to solar panel owners who feed their excess energy into the grid. While 1,500 workers are stationed at Diablo, some 70,000 work in the state’s solar industry, which angrily charges that Newsom’s pro-nuclear, anti-green positions are crippling the state’s top job creator.

Indeed, the irony of these twin economies heading in opposite energy directions is hard to ignore. In the 1970s, much of America’s early anti-nuclear movement was inspired by mass demonstrations led by German Greens (with the slogan “Atomkraft? Nein, danke!”). Both movements succeeded in massively moving their communities toward a renewable future.

But at this critical moment, Germany appears to be moving beyond nuclear power, while California clings to a hugely controversial technology it had once planned to transcend.

Germany Shutters Remaining Reactors

By John LaForge

Germany has switched off the last of its nuclear power reactors for good.

The world’s press made much of “Europe’s largest economy” finally going nuclear-free, a renunciation of poison power that Germany has been planning for since 2011.

The country will replace the puny 6% of electricity provided by its last three plutonium/MOX-fueled behemoths with solar and wind generators, geothermal, conservation, and other renewables that already provide 46.9% of the country’s electricity.

“The position of the German government is clear: nuclear power is not green. Nor is it sustainable,” Steffi Lemke, Germany’s Federal Minister for the Environment and Consumer Protection and a Green Party member, told CNN. Minister Lemke told France’s Le Monde, “The risks of nuclear power are ultimately unmanageable,” after making an April visit to Japan’s Fukushima disaster zone.

Earlier, the 1986 reactor catastrophe at Chernobyl in Ukraine created a plume of radioactive fallout that doused large parts of Germany, and threw nuclear power in the doghouse for millions.

The March 2011 earthquake and tsunami that smashed and flooded the Fukushima-Daiichi complex in Japan resulted in three simultaneous reactor meltdowns and the largest radiation release to the environment — still ongoing — in history. For most in Germany, Fukushima was confirmation “that assurances that a nuclear accident of a large scale can’t happen are not credible,” Miranda Schreurs, professor of environment and climate policy at the Technical University of Munich, told CNN.

Three days after the earthquake and tsunami, Germany’s then-Chancellor Angela Merkel called Fukushima an “inconceivable catastrophe for Japan” and a “turning point” which it was, at least for Germany.

Plenty of other European countries are rejecting nuclear, CNN reported recently. Denmark passed a resolution in the 1980s not to build new reactors. Switzerland voted in 2017 to phase out nuclear. Italy closed its last reactors in 1990, and Austria’s one reactor site has never operated. Lucky for them.

“Germany’s phase-out of nuclear power is a historic event and an overdue step in energy terms,” Simone Peter, president of the German Renewable Energy Federation, told CNN. “It is high time that we leave the nuclear age behind and consistently organize the renewable age.”

Stop Holtec’s Radioactive Wastewater Dump

By Mari Inoue

Holtec International wants to dump radioactive wastewater from decommissioning nuclear facilities. People and elected officials are fighting back to halt such outrageous, unilateral plans.

Founded in 1986 in New Jersey by Kris Singh, Holtec manufactures dry storage and transport casks for highly radioactive spent nuclear fuel waste from reactors. The company also built the Central Spent Fuel Storage Facility inside the Chernobyl Exclusion Zone in 2021 for Energoatom, Ukraine’s national nuclear energy company. Its wholly-owned subsidiary, Holtec Decommissioning International, provides dismantling work for Holtec nuclear power reactors, including Indian Point on the Hudson River, 24 miles north of New York City, and Pilgrim Nuclear Station on Cape Cod Bay in Massachusetts.

 

On February 2, 2023, at a public forum of the Indian Point Decommissioning Oversight Board (DOB), Holtec announced its plans to dump highly radioactive wastewater from Indian Point’s fuel cooling pools into the Hudson River. On April 27, 2023, Holtec explained that approximately 1.3-to-1.5 million gallons from the radioactive fuel pools, a refueling water storage tank, the reactor cavity, and elsewhere need to be “processed and discharged via its Liquid Waste Processing System.” Holtec intends to begin dumping as early as September. The “processed” wastewater that will be dumped into the river contains tritium (radioactive hydrogen) and possibly other radioactive isotopes.

Tritium is clinically known to cause more harm and death to living cells than gamma rays. Numerous studies show that tritium produces common radiogenic impacts including cancerous tumors, reproductive and genetic effects, and developmental abnormalities. Studies also indicate that smaller doses of tritium can cause more mutations, chromosome damage, and cell death than larger doses. Tritium crosses the placenta and can impact an embryo or fetus.

In Massachusetts, fisheries and neighbors along Cape Cod Bay are pushing back against Holtec’s plans to dump more than 1.1 million gallons of radioactive wastewater into the Bay from Pilgrim. A warning issued by the Environmental Protection Agency states that Holtec’s unauthorized discharge into the Bay would be in violation of the Clean Water Act. Holtec agreed to cooperate with an independent environmental study, but refused U.S. Senator Ed Markey’s demand that they pay for it.

In New York, State Senator Pete Harckham and Assemblywoman Dana Levenberg introduced legislation that makes it unlawful to release any radiological agents into the Hudson River during decommissioning of nuclear reactors, and failure to comply shall result in fines. The “Save the Hudson” bill passed the state senate unanimously, and activists are calling on the Assembly to call a special session to do the same after it initially failed June 10.

In early April, U.S. Senators Chuck Schumer and Kirsten Gillibrand wrote to the Nuclear Regulatory Commission expressing “significant concerns” regarding Holtec’s planned discharge of large amounts of radioactive wastewater from Indian Point. The NRC dismissed their concerns in a letter that states “to date, all releases at Indian Point have been a small fraction of the allowable limits for such releases.”

As of early May, more than two dozen municipal resolutions were adopted in New York, with more pending, to stop Holtec’s dumping plans. On May 6, 2023, the Save the River Rally at Cortlandt Waterfront Park was organized by the town of Cortlandt. Hundreds of local residents, kayakers, environmental activists, and public elected officials participated to demand the dumping be halted. They are calling for keeping the waste contained onsite.

Decades of Radioactive Dumping Tied to Cancers at Coldwater Creek

DOE and Army Corps accused of negligence over St. Louis radioactive waste

By Bob Mayberry

Last year the U.S. Army Corps of Engineers declined to test for radioactive contamination inside the Jane Elementary School in northern St. Louis, in spite of considerable community pressure to do so. Outside testing eventually revealed levels of contamination 22 times higher than background levels in the playground, and 12 times higher than average inside the gymnasium. The school was closed and local lawmakers persuaded the Corps to conduct new tests.

But it was not until early this year that the Department of Energy (DOE) finally requested permission to test for contamination along Coldwater Creek, and even then only at one site, the historic Fort Belle Fontaine, the first U.S. military installation west of the Missouri River. Meanwhile, reports of disease and incidences of cancer at several sites along the creek continue to surface, and residents complain that federal agencies do not communicate about the dangers in the area.

Brief History of Radioactivity in Metro St. Louis – Missouri Coalition for the Environment

Jane Elementary School sits adjacent to Coldwater Creek, which runs 19 miles between the St. Louis airport and the Missouri River. In 2014, state health officials reported higher incidences of rare cancers associated with low-dose radioactive exposure in areas adjacent to the creek. In 2016, the Centers for Disease Control and Prevention recommended residents avoid getting into or playing near the creek, and in 2019 the federal Department of Health and Human Services released a report concluding that “Radiological contamination in and around Coldwater Creek … could have increased the risk of some types of cancer in people who played or lived there.”

In early March, the Missouri House of Representatives heard testimony about compensation for St. Louis area residents exposed to radioactive waste. State Representative Tricia Byrnes accused the DOE of negligence for failing to remove “the considerable amount of waste around the region.”

The problems began during World War II when the Mallinckrodt Chemical Company began to secretly process uranium ore north of downtown St. Louis as part of the Manhattan Project. Radioactive byproducts were first stored on the St. Louis airport’s northern edge, adjacent to Coldwater Creek, then later trucked to sites further east along the creek, including a site near where the Jane Elementary School now sits. Mallinckrodt officials dismissed the dangers of radioactive waste in a 1946 statement to the St. Louis Post-Dispatch, claiming the waste materials “were not radioactive and not dangerous.”

Brief History of Radioactivity in Metro St. Louis  – Missouri Coalition for the Environment

Though processing of uranium by Mallinckrodt Co. ended in 1957, radioactive and chemical waste materials continued to be shipped to and from sites in and around St. Louis. Between 1957 and 1966, uranium ore was processed near Weldon Spring, west of Coldwater Creek along the Missouri River. Approximately 1.5 million cubic yards of radioactive and chemical waste were piled 75 feet high along Route 94 South, near another St. Louis public school. In 1973, nearly 8,700 tons of barium sulfate waste from the Coldwater Creek area was mixed with 40,000 tons of topsoil and shipped to a landfill in Weldon Spring. Residents claim not to have been notified about any of these dangerous practices.
