'Floating Chernobyl?' Nuclear Plant Heads Across Arctic Circle
By Eon Higgins
Its official name is the "Akademik Lomonosov," but critics call it a "floating Chernobyl."
Whichever title you prefer, the floating barge nuclear plant is heading across the Arctic Circle. A project of the Russian government, the plant is headed to the far eastern town of Pevek on Russia's Arctic north coast to provide power to energy projects in the North Pole.
According to CNN:
The Admiral Lomonosov will be the northernmost operating nuclear plant in the world, and it's key to plans to develop the region economically. About 2 million Russians reside near the Arctic coast in villages and towns similar to Pevek, settlements that are often reachable only by plane or ship, if the weather permits. But they generate as much as 20 percent of country's GDP and are key for Russian plans to tap into the hidden Arctic riches of oil and gas as Siberian reserves diminish.
The Lomonosov has been the target of criticism from Greenpeace for years. The environmental group first coined the name "Chernobyl on ice."
But the company behind Lomonosov, Rosatom, takes exception at comparing its barge plant to the famed site of the world's worse domestic nuclear disaster.
"It's totally not justified to compare these two projects," the Lomonosov's chief engineer for environmental protection, Vladimir Iriminku, told CNN. "These are baseless claims, just the way the reactors themselves operate work is different."
The barge's operators have learned from the disaster at Fukushima, Japan as well, they said.
"This rig can't be torn out of moorings, even with a 9-point tsunami, and we've even considered that if it does go inland, there is a backup system that can keep the reactor cooling for 24 hours without an electricity supply," said Lomonosov deputy director Dmitry Alekseenko.
Bellona, a nonprofit that observes nuclear projects and their environmental impacts, found in April that 24 hours could be insufficient time to avoid disaster if the rig was torn out of its moorings and landed somewhere where escape is difficult due to the polar environment.
In an interview with The Verge, Dale Klein, the former head of the Nuclear Regulatory Commission under President George W. Bush, called the plant's nickname a "scare tactic." However, Klein acknowledged that the potential for disaster from the Lomonosov could be catastrophic if something were to go wrong.
"If there were a problem out in the middle of the ocean, you would probably never see it on land," said Klein. "Or, you might be able to measure it, but it would be such a minimal impact [on land] because the ocean is so big. But if you have this barge that's anchored providing electricity 24 hours, seven days a week, and you had a spill, then it could get into the environment locally onshore."
"And so," said Klein, "you'd have to make sure that that never happens."

Summer and fall are great seasons to enjoy the outdoors. But if you're already spending extra time outside because of the COVID-19 pandemic, you may be out of ideas on how to make fresh-air activities feel special. Here are a few suggestions to keep both adults and children entertained and educated in the months ahead, many of which can be done from the comfort of one's home or backyard.
The coronavirus may linger in the air in crowded indoor spaces, spreading from one person to the next, the World Health Organization acknowledged on Thursday, as The New York Times reported. The announcement came just days after 239 scientists wrote a letter urging the WHO to consider that the novel coronavirus is lingering in indoor spaces and infecting people, as EcoWatch reported.

It is undisputed that vitamin D plays a role everywhere in the body and performs important functions. A severe vitamin D deficiency, which can occur at a level of 12 nanograms per milliliter of blood or less, leads to severe and painful bone deformations known as rickets in infants and young children and osteomalacia in adults. Unfortunately, this is where the scientific consensus ends.
Where Does the Deficiency Begin?<p>Nobody knows exactly how much vitamin D a person actually needs. The question of when a deficiency starts is correspondingly controversial. However, vitamin D is becoming increasingly popular.Not only is the pseudo-scientific literature on the "sun vitamin" experiencing an upswing, but the number of published studies has also increased enormously in recent years. For example, in 2019 <a href="https://academic.oup.com/edrv/article/40/4/1109/5126915" target="_blank">a study found that</a> Vitamin D is responsible for keeping the skeleton functional and is associated with cardiovascular diseases, type 2 diabetes and various types of cancer. <br></p>
An All-Rounder<p>Vitamin D levels in the body rise and fall according to sun exposure. If sufficient UV rays reach the skin, the body is able to produce the vitamin itself. However, the human body only derives an estimated 10 to 20 percent of its daily requirement from food.</p><p>The vitamin D that we synthesize from sunlight or food is not biologically active at first. Before the kidneys can produce the biologically active form of the vitamin, known as calcitriol, and release it into the blood, some metabolic processes must take place beforehand.</p><p>In addition, many organs have receptors to which the precursor of calcitriol binds. Further, this substance is also present in blood.</p><p>From this precursor, the organs then produce calcitriol themselves, which the body then uses for countless other processes in the body. This form of vitamin D thus regulates insulin secretion, inhibits tumor growth, and promotes the formation of red blood cells as well as the survival and activity of macrophages, which are important for the <a href="https://www.mdpi.com/2072-6643/5/7/2502/htm" target="_blank">immune system.</a></p>
Low Vitamin D, Severe COVID-19 Disease?<p>A research study carried out <a href="https://www.sciencedirect.com/science/article/pii/S2352364620300067?via%3Dihub" target="_blank">at the University of Hohenheim</a> has now established a link between vitamin D deficiency, certain previous diseases, and severe cases of COVID-19.</p><p>According to the study, "there is a lot of evidence that several non-communicable diseases (high blood pressure, diabetes, cardiovascular diseases, metabolic syndrome) are associated with low vitamin D plasma levels. These comorbidities, together with the often accompanying vitamin D deficiency, increase the risk of severe COVID-19 events."</p><p>"This statement is completely correct," said Martin Fassnacht, head of endocrinology at the University Hospital of Würzburg. However, he qualifies that it is a pure association, "i.e. a mere observation that these events occur together.</p><p>Dr. Fassnacht is very critical of the hype surrounding vitamin D, but not because he denies the vitamin serves important functions. However, studies on humans have not been able to show that vitamin D has the healing powers many often propagate.</p><p>Fassnacht says, "If you take a closer look, the hopes that the administration of vitamin D has a healing effect have not been confirmed so far."</p>
Association Versus Intervention Studies<p>Many studies on the vitamin are association or observational studies. "By definition, these studies cannot prove the causal relationship, but only point to mere correlations," said Fassnacht. The physician tries to illustrate this with an example:</p><p>"Imagine two groups of 80-year-olds. One group is spry, active and does sports. If you compare them with another group living in nursing homes, the difference in vitamin D levels will be dramatic. Life expectancy would also be extremely different."</p><p>But to try to explain the difference in fitness by vitamin D status alone is far too simplistic. "Vitamin D levels are a good measure of how sick someone is. But not more," says Fassnacht. </p><p>According to Fassnacht, none of the intervention studies carried out to date -- that specifically examined the effect of vitamin D on various diseases -- has been able to confirm the previous association and laboratory studies or the presumed positive effect of vitamin D.</p>
Further Research Is Needed<p>"If a coronavirus infection is suspected, it is therefore absolutely necessary to check the vitamin D status and quickly correct any possible deficit," said the recommendation of the paper published by the University of Hohenheim.</p><p>"Studies are underway to see whether vitamin D helps in COVID-19 infection, but I personally do not believe that this is really the case," says endocrinologist Fassnacht. Nevertheless, he says it is of course useful to carry out these studies.<br></p><p>"I don't want to rule out that there are actually subgroups of people who benefit from an additional vitamin D dose," he says. After all, this has been proven to be the case with a severe deficit.</p><p>In view of the study situation, Fassnacht does not think much of preventive, nationwide vitamin D substitutes. "My belief that the vitamin helps somewhere is very low. But, of course, I can be wrong."</p>
