Electricity and fear: The trouble with nuclear energy
Although everyone knows that coal-based energy is a thing of the past, declarations about nuclear power plants somehow do not want to enter into force.
No other power-generating device raises as much concern as the nuclear reactor. Because of this, until recently the future of the entire energy sector has been determined by its past.
On the eve of the pandemic, the European energy sector found itself at a crossroads, somewhere between Great Britain, Germany and Poland. Five years ago, across the English Channel, the then Prime Minister David Cameron announced an ambitious program to build 12 new nuclear power plants with a total capacity of 16 GW. While developing renewable energy resources, they would allow the United Kingdom to reduce carbon dioxide emissions from the energy sector to almost zero. Soon after, Cameron came up with the idea of a referendum on leaving the EU – and Brexit reset all long-term British plans. However, the British are already producing electricity in a very sustainable way. Almost 38% comes from renewable sources, about 20% from nuclear power plants, while the remainder is provided by gas-powered plants, the only ones that emit CO2.
Meanwhile in Germany, the aversion towards nuclear energy has been growing for years. Finally, following the Fukushima disaster in March 2011, chancellor Angela Merkel announced that all nuclear power plants would be shut down by 2022. For the first few years, the great Energiewende (energy transformation) plan seemed to be going well. Thanks to subsidies and increased electricity prices for individual customers, the intensive development of wind farms and solar power plants continued. However, no technological solution has been found to overcome the main weakness of renewable energy sources: plants running on renewable sources work on average for 20-30% of the day and remain completely dependent on whether the wind blows or the sun shines. Because of this, they are not able to handle energy peaks. In turn, when a gale comes, suddenly there is a network overload due to excess power. In both these extreme cases, the entire country is at risk of blackout, and the risk of collapsing energy supplies increases significantly when more than 30% is obtained from renewable sources. Safety requires the maintenance of traditional power plants, which due to their flexibility, stabilize the entire system.
In Germany, as subsequent nuclear reactors began to shut down, lignite-fired power plants started to play a key role. Unlike nuclear plants, they devastate the natural environment not only due to CO2 emissions, but also the need to expand opencast mines. A huge wave of criticism from environmentalists and Berlin's goal to lead by example in the fight against global warming have brought an adjustment in strategy. Today, coal-fired power plants are being replaced by gas-fired ones that emit one-third less carbon dioxide. Russia will provide fuel for them via the Nord Stream and Nord Stream 2 gas pipelines. However, withdrawal from the decommissioning of nuclear power plants is now out of the question.
In turn, the development of renewable energy in Poland is suffering, despite the construction of one or more nuclear power plants having been announced two decades ago. Before the pandemic, the government envoy for strategic energy infrastructure Piotr Naimski claimed that by the end of 2045 as many as six nuclear reactors with a total capacity of 6 GW would be built. Although everyone knows that coal-based energy is a thing of the past, declarations about nuclear power plants somehow do not want to enter into force. And this is a very complicated undertaking, during which any disregard of security standards can awaken demons from the past.
A pile of trouble
"In fifteen years, nuclear power will provide electricity too cheap to measure its consumption," the head of the American Atomic Energy Commission, Lewis Strauss, prophesied in 1954. By the end of that decade, energy corporations had overcome technological barriers. "Westinghouse has perfected the PWR reactor, the water-pressure reactor, and GE [General Electric] the BWR reactor, boiling water reactor," explains Daniel Yergin in the The Quest: In Search of Energy. These two types of first generation reactors have spread throughout the world. By 1970, 15 nuclear power plants had launched in 62 countries and the construction of a further 89 had begun. Most of them were located in the US, USSR, UK, France, Japan and West Germany. Three years later, the first oil crisis erupted and it seemed certain that highly developed countries would base their future on nuclear power plants. However, the first problems began to emerge.
The first generation, 1000 MW water-pressure reactor generated as much as 20 tons of radioactive waste annually. Initially, the Americans placed it into metal containers and buried it in the ocean. The Soviets did the same. Protests by environmental organizations led to containers with a guarantee of durability of a thousand years starting to be buried in the Nevada desert – ignoring the fact that the half-life of plutonium-239 is about 24,400 years. In other countries, old mines were used as waste dumps. The French coped with this problem exemplarily by building a plant at La Hague specializing in the recovery of radioactive uranium and plutonium from waste. Later, these elements are enriched and sold to energy companies. During the 1980s, many countries – including Japan, West Germany, Belgium and Switzerland – began to use the services of the French.
In addition to waste, investment costs have become an equally large problem. "Emerging ecological movements, especially anti-nuclear ones, forced additional reviews and changes. It was necessary to thicken the concrete walls, and remove pipeline installations and rework them. Power plants had to be redesigned, even several times during construction," emphasizes Yergin. He writes: "Power plants also became more expensive because of inflation and later, the high interest rates on loans. Instead of six years, construction took ten; it also cost money. The power plants, which were to cost $200million, ultimately cost $2billion." Later, they produced the cheapest electricity on the market, but gigantic expenses had to be included in its price. While the French model handles waste well, investment costs remain the Achilles' heel of nuclear energy to this day, even if they are less important than the media and public fear.
Awaiting the apocalypse
"There is nothing in the laws of nature that stops us from building better nuclear power plants. We are stopped by a deep justified public distrust. The public distrusts the experts because they claimed to be infallible," writes Freeman Dyson, a physicist who participated in the construction of the first reactors, in the book Imagined Worlds. The distrust of nuclear energy emerged gradually. In the 1960s, everyone remembered the fate of Hiroshima and Nagasaki, but the fear of radioactive radiation had not yet paralysed ordinary people. Experts managed to convince Western societies that the nuclear power plant hardly differed from the coal-fired power plant. All it needs is access to a lot more coolant for the reactor, preferably a huge water tank.
The sense of security began to fade not because of a failure, but catastrophic scenarios loved by the press, especially in West Germany. In October 1975, Der Spiegel very vividly presented to readers what would happen if the reactor at a power plant built near Ludwigshafen overheated. "The molten reactor core will penetrate the surrounding protective structures. It will sink into the ground at a speed of two to four meters per hour. The amount of radiation emitted would correspond to the radiation of a thousand bombs such as the one dropped on Hiroshima," the newspaper forecasted, estimating the number of victims at 100,000 killed immediately and about 1.6 million "dying slowly" due to radiation sickness. Such apocalyptic visions interested Hollywood, resulting in the neo-thriller entitled The China Syndrome. In specialist jargon, this name means the severe meltdown of the core components of the reactor.
Lo and behold, two weeks after the film's release, on 28th March 1979, there was a failure at the Three Mile Island nuclear power plant located on an artificial island. Pipes supplying coolant to the reactor burst when the back-up cooling system was disconnected for inspection. The reactor had warmed up, but the safety measures worked. Each reactor is managed using control rods. They are made of alloys that absorb neutrons. Sliding the control rods in between the fuel rods slows down the chain reaction. Pulling them out has the opposite effect. When the reactor overheats, all control rods fall into the core, quenching the reaction.
This happened at Three Mile Island. However, due to the pipes bursting, water poured out onto the reactor jacket and immediately evaporated, forming a mixture of oxygen and hydrogen under the dome of the power block. One spark could have blown up the power plant. The following day, technicians pumped off hazardous, radioactive gases outside. The residents of nearby Harrisburg panicked. About 80,000 people attempted to escape the city in cars. The US energy minister James Schlesinger's assurances that the radiation only increased by around 0.03 rem and would not hurt anyone fell on deaf ears. Those who have seen The China Syndrome knew better. It wasn't until five days later, when President Jimmy Carter personally visited Three Mile Island and in the presence of TV cameras toured the area, that the panic was subjugated. However, the misfortunes of nuclear power plants were only just beginning.
The weakest link
The owners of the plant, the Westinghouse group, largely caused the Three Mile Island disaster. The power plant was built in a rush to make it operational before 30th December 1978, in order for the company to gain a $40 million tax break. After launching the reactor, it turned out that the coolant supply pipes were leaking. At that point, the management ordered temporary sealing of leaks, after which the test of the emergency cooling system was performed, starting with its shutdown. This was done on the assumption that the main pipes would still last a little longer. "The accident was caused by a series of relatively small equipment failures followed by operator error," the head of the commission investigating the causes of the disaster, Admiral Hyman G. Rickover, wrote in his report. Fortunately, none of the Westinghouse executives were so thoughtless as to deactivate the other safeguards. Seven years later, it turned out that even such recklessness is possible.
On the night of 26th April 1986, the management of the Chernobyl power plant began to experiment with manual control of the reactor in block 4. For complete freedom, all automatic security systems were turned off. During the experiments, the stack heated up rapidly, and the control rods blocked by the staff did not automatically quench the chain reaction. Then the pipes supplying water to the cooling system burst. As in Three Mile Island, the water evaporated by the hot reactor turned into hydrogen and oxygen. The explosion of this mixture tore the dome and threw a 500-ton piece of concrete into the air, which a moment later fell into the reactor, breaking it completely. 50 tons of fuel escaped outside and the core melted. Vast areas of northern Ukraine and Belarus became contaminated due to the radioactive cloud. 50,000 residents of the nearby town of Pripyat and surrounding villages were evacuated.
As a result of the disaster, 31 people lost their lives (mainly irradiated firefighters). UNSCEAR (UN Scientific Committee on Effects of Atomic Radiation) found that there were many more casualties: a 2000 report found that of about 600 employees of the power plant and firefighters, 237 were diagnosed with radiation sickness symptoms. Of these, 28 people died. According to the report, epidemiologists have not observed an increase in the incidence of cancer in the most contaminated areas, except for higher than average rates of thyroid cancer. No genetic defects were found in the offspring of irradiated persons.
A quarter of a century later, the 'Chinese syndrome' became Japanese. Two oil crises in the 1970s encouraged the government of Japan to finance the construction of 50 nuclear reactors. They guaranteed energy security for the state. However, haste made them forget about their side effects in a country where earthquakes happen regularly. The Fukushima reactor was built right on the seafront. When massive shocks (9 on the Richter scale) came on 11th March 2011, the security systems functioned properly. The reactors were automatically quenched and the cooling system switched to the emergency power supply. Nothing bad would have happened if it weren't for the sea. Tectonic shocks caused a tsunami wave of 15-metre heights, and the breakwater was only six-metres high. Huge amounts of water flooded the power plant. The power generators went down and the reactor core suddenly stopped being cooled. Then the water evaporated and the hydroxide mixture exploded.
About 10 times less radioactive substance escaped outside than in Chernobyl, and no-one was killed during the event. The first person irradiated as a result of the disaster's aftermath did not die until September 2018. Yet again, however, a wave of fear swept through the entire world.
The sum of fears
The disaster in Fukushima was a strong blow to the nuclear energy sector – which even without it, suffered bad press – and led to public trepidation, even though by the mid-1980s the number of reactors operating worldwide had reached 430 and stopped growing. New ones were still being built in France, Japan, the USSR (later, Russia), South Korea and China, but elsewhere they were gradually dismantled. The only country that had based their entire energy system on nuclear power plants was France, where they produce over 80% of electricity. Finland is also focusing on the development of nuclear energy. Two nuclear power plants currently generate around 30% of the country's energy, and once the third one is built, this will reach 60% (the rest is to come from renewable sources).
Most countries, however, still recognize the nuclear industry as a dead end. The emergence of much better third generation reactors that use less uranium, while reducing the amount of waste, did not change that. Developed by two companies – the French Framatome and the German Siemens – the EPR (European Pressurized Reactor) has a quadruple safety system and reinforcement that can withstand even the impact of an aircraft crash. In turn, the ESBWR (Economic Simplified Boiling Water Reactor) by GE Hitachi, apart from showing similar resistance, requires minimal amounts of coolant and discharges excess heat directly into the atmosphere.
There are more innovative constructions, but they have started to generate interest only recently, thanks to the rapid development of Asian countries, and thus an increase in demand for cheap electricity. A nuclear power plant uses roughly 30-50 tons of uranium per year. At a market price of around $55 per kilogram, a cost of fuel of around $2.5 million a year is very cheap – 100 times cheaper than the cost of fuel for a coal-fired power plant fuel. It is estimated that known uranium deposits will last for about 300 years. At the same time, as with crude oil, this deadline may prove to be much more distant, since no new ones have been sought for years. Therefore, it should not come as a surprise that in April 2019 China presented a plan for the vast expansion of its nuclear energy sector. While today the total capacity of Chinese nuclear power plants is about 42 GW, it will exceed 100 GW in 100 years. Then, the People's Republic of China will overtake the US in this field. South Korea has presented slightly less ambitious goals, announcing an increase in nuclear power by one-third.
And what path will the European Union take? The fight against CO2 emissions determines the direction of its energy policy, and renewable energy sources are a priority. However, to fully base their economy on them, efficient energy storage is necessary – methods capable of accumulating electricity at times of overproduction and releasing it in the absence of sun and wind. Even lithium-ion cells cannot fully cope with this task. Attempts are being made at avoiding the lack of this element by designing self-sufficient buildings that draw energy from solar batteries and heat pumps. However, in the scale of cities and entire countries, large power plants cannot be replaced, and the only ones that do not emit carbon dioxide are nuclear power plants. This fact means that even in Europe, their slow renaissance continues. For now, countries on the outskirts of the EU (Finland, Hungary, Lithuania, the Czech Republic and Slovakia) are modernizing old plants or building new ones. In just one year, the construction of over 60 new reactors began.
Despite public resentment, more investments will begin soon. Right now, fear of the 'China syndrome' is weaker than fear of the effects of global warming and sudden energy shortages and blackouts.

What is human dignity? Here's a primer, told through 200 years of great essays, lectures, and novels.
- Human dignity means that each of our lives have an unimpeachable value simply because we are human, and therefore we are deserving of a baseline level of respect.
- That baseline requires more than the absence of violence, discrimination, and authoritarianism. It means giving individuals the freedom to pursue their own happiness and purpose.
- We look at incredible writings from the last 200 years that illustrate the push for human dignity in regards to slavery, equality, communism, free speech and education.
The inherent worth of all human beings<p>Human dignity is the inherent worth of each individual human being. Recognizing human dignity means respecting human beings' special value—value that sets us apart from other animals; value that is intrinsic and cannot be lost.</p> <p>Liberalism—the broad political philosophy that organizes society around liberty, justice, and equality—is rooted in the idea of human dignity. Liberalism assumes each of our lives, plans, and preferences have some unimpeachable value, not because of any objective evaluation or contribution to a greater good, but simply because they belong to a human being. We are human, and therefore deserving of a baseline level of respect. </p> <p>Because so many of us take human dignity for granted—just a fact of our humanness—it's usually only when someone's dignity is ignored or violated that we feel compelled to talk about it. </p> <p>But human dignity means more than the absence of violence, discrimination, and authoritarianism. It means giving individuals the freedom to pursue their own happiness and purpose—a freedom that can be hampered by restrictive social institutions or the tyranny of the majority. The liberal ideal of the good society is not just peaceful but also pluralistic: It is a society in which we respect others' right to think and live differently than we do.</p>

The future of dignity<p>Around the world, people are still working toward the full and equal recognition of human dignity. Every year, new speeches and writings help us understand what dignity is—not only what it looks like when dignity is violated but also what it looks like when dignity is honored. In his posthumous essay, Congressman Lewis wrote, "When historians pick up their pens to write the story of the 21st century, let them say that it was your generation who laid down the heavy burdens of hate at last and that peace finally triumphed over violence, aggression and war."</p> <p>The more we talk about human dignity, the better we understand it. And the sooner we can make progress toward a shared vision of peace, freedom, and mutual respect for all. </p>
Scientists find that bursts of gamma rays may exceed the speed of light and cause time-reversibility.
- Astrophysicists propose that gamma-ray bursts may exceed the speed of light.
- The superluminal jets may also be responsible for time-reversibility.
- The finding doesn't go against Einstein's theory because this effect happens in the jet medium not a vacuum.

Is Bitcoin akin to 'digital gold'?
- In October, PayPal announced that it would begin allowing users to buy, sell, and hold cryptocurrencies.
- Other major fintech companies—Square, Fidelity, SoFi—have also recently begun investing heavily in cryptocurrencies.
- While prices are volatile, many investors believe cryptocurrencies are a relatively safe bet because blockchain technology will prove itself over the long term.

Bitcoin as 'digital gold'<p>Still, it could take years for people to start using cryptocurrencies for everyday purchases on a large scale. Despite this, many cryptocurrency advocates see digital currencies, particularly Bitcoin, as a way to store value—digital gold, essentially.</p><p style="margin-left: 20px;">"I don't think Bitcoin is going to be used as a transactional currency anytime in the next five years," billionaire investor Mike Novogratz recently told <a href="https://www.bloomberg.com/news/articles/2020-10-23/novogratz-says-bitcoin-is-digital-gold-not-a-currency-for-now?srnd=markets-vp" target="_blank">Bloomberg</a>.

Singapore has approved the sale of a lab-grown meat product in an effort to secure its food supplies against disease and climate change.

For the initial run, the cultured chicken meat will be sold as an ingredient in "chicken bites."</p><p>"Singapore has long been a leader in innovation of all kinds, from information technology to biologics to now leading the world in building a healthier, safer food system.

These cultured stem cells are then placed in a bioreactor, essentially a fermenter for fleshy cells. The bioreactor contains scaffolding materials to keep the growing tissue from falling apart as well as a growth material—the sugars, salts, and other nutrients the tissue needs to grow. As the cells grow, they begin to differentiate into the muscle, fat, and other cells of meat tissue. Once grown, the tissues are formed into a meat product to be shipped to restaurants and supermarkets.</p>

Credit: Our World in Data<p>Singapore's approval is an important step in support for clean meats—so-called because they don't require animal slaughter and would likely leave a reduced carbon footprint—but hurdles remain before widespread adoption is possible.</p><p>The most glaring is the price. The first lab-grown hamburger was eaten in London in 2013. <a href="https://www.bbc.com/news/science-environment-23576143" target="_blank" rel="noopener noreferrer">It cost roughly $330,000</a>.

Finally, not all countries may be as receptive as Singapore. Countries with large, entrenched meat industries may protect this legacy industry through a protracted and difficult regulatory process. Though, the meat industry itself is investing in lab-grown meat. Tyson Foods, for example, has <a href="https://euromeatnews.com/Article-Tyson-Foods-announces-investment-in-clean-meat/697" target="_blank" rel="noopener noreferrer">invested in the food-tech startup Memphis Meats</a>, the company that debuted the world's first beef meatball.</p><p>"I would imagine what will happen is the U.S., Western Europe and others will see what Singapore has been able to do, the rigours of the framework that they put together. And I would imagine that they will try to use it as a template to put their own framework together," <a href="https://www.reuters.com/article/us-eat-just-singapore/singapore-approves-sale-of-lab-grown-meat-in-world-first-idUSKBN28C06Z" target="_blank" rel="noopener noreferrer">Tetrick told Reuter's during an interview</a>.</p><p>Regardless of the challenges, the demand for meat substitutes is present and growing.

And those figures do not include chickens killed in dairy or egg production.</p><p>If brought to scale and widely available, clean meats could become serious competitors to traditional meat. <a href="https://bigthink.com/technology-innovation/meat-alternatives" target="_self">One report has even predicted</a> that 60 percent of the meat people eat by 2040 won't come from slaughtered animals. It could be just the thing for people looking for a meat substitute but who find tofurkey as distasteful as, well tofurkey.</p>
