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.

Scientists used CT scanning and 3D-printing technology to re-create the voice of Nesyamun, an ancient Egyptian priest.
- Scientists printed a 3D replica of the vocal tract of Nesyamun, an Egyptian priest whose mummified corpse has been on display in the UK for two centuries.
- With the help of an electronic device, the reproduced voice is able to "speak" a vowel noise.
- The team behind the "Voices of the Past" project suggest reproducing ancient voices could make museum experiences more dynamic.
Howard et al.<p style="margin-left: 20px;">"While this approach has wide implications for heritage management/museum display, its relevance conforms exactly to the ancient Egyptians' fundamental belief that 'to speak the name of the dead is to make them live again'," they wrote in a <a href="https://www.nature.com/articles/s41598-019-56316-y#Fig3" target="_blank">paper</a> published in Nature Scientific Reports. "Given Nesyamun's stated desire to have his voice heard in the afterlife in order to live forever, the fulfilment of his beliefs through the synthesis of his vocal function allows us to make direct contact with ancient Egypt by listening to a sound from a vocal tract that has not been heard for over 3000 years, preserved through mummification and now restored through this new technique."</p>
Connecting modern people with history<p>It's not the first time scientists have "re-created" an ancient human's voice. In 2016, for example, Italian researchers used software to <a href="https://www.smithsonianmag.com/smart-news/hear-recreated-voice-otzi-iceman-180960570/" target="_blank">reconstruct the voice of Ötzi,</a> an iceman who was discovered in 1991 and is thought to have died more than 5,000 years ago. But the "Voices of the Past" project is different, the researchers note, because Nesyamun's mummified corpse is especially well preserved.</p><p style="margin-left: 20px;">"It was particularly suited, given its age and preservation [of its soft tissues], which is unusual," Howard told <em><a href="https://www.livescience.com/amp/ancient-egypt-mummy-voice-reconstructed.html" target="_blank">Live Science</a>.</em></p><p>As to whether Nesyamun's reconstructed voice will ever be able to speak complete sentences, Howard told <em><a href="https://abcnews.go.com/Weird/wireStory/ancient-voice-scientists-recreate-sound-egyptian-mummy-68482015" target="_blank">The Associated Press</a>, </em>that it's "something that is being worked on, so it will be possible one day."</p><p>John Schofield, an archaeologist at the University of York, said that reproducing voices from history can make museum experiences "more multidimensional."</p><p style="margin-left: 20px;">"There is nothing more personal than someone's voice," he told <em>The Associated Press.</em> "So we think that hearing a voice from so long ago will be an unforgettable experience, making heritage places like Karnak, Nesyamun's temple, come alive."</p>

New research suggests you can't fake your emotional state to improve your work life — you have to feel it.
What is deep acting?<img type="lazy-image" data-runner-src="https://assets.rebelmouse.io/eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJpbWFnZSI6Imh0dHBzOi8vYXNzZXRzLnJibC5tcy8yNTQ1NDk2OS9vcmlnaW4uanBnIiwiZXhwaXJlc19hdCI6MTYxNTY5MzA0Nn0._s7aP25Es1CInq51pbzGrUj3GtOIRWBHZxCBFnbyXY8/img.jpg?width=1245&coordinates=333%2C-1%2C333%2C-1&height=700" id="ddf09" class="rm-shortcode" data-rm-shortcode-id="9dc42c4d6a8e372ad7b72907b46ecd3f" data-rm-shortcode-name="rebelmouse-image" data-width="1245" data-height="700" />
Arlie Russell Hochschild (pictured) laid out the concept of emotional labor in her 1983 book, "The Managed Heart."
Credit: Wikimedia Commons<p>Deep and surface acting are the principal components of emotional labor, a buzz phrase you have likely seen flitting about the Twittersphere. Today, "<a href="https://www.bbc.co.uk/bbcthree/article/5ea9f140-f722-4214-bb57-8b84f9418a7e" target="_blank">emotional labor</a>" has been adopted by groups as diverse as family counselors, academic feminists, and corporate CEOs, and each has redefined it with a patented spin. But while the phrase has splintered into a smorgasbord of pop-psychological arguments, its initial usage was more specific.</p><p>First coined by sociologist Arlie Russell Hochschild in her 1983 book, "<a href="https://www.ucpress.edu/book/9780520272941/the-managed-heart" target="_blank">The Managed Heart</a>," emotional labor describes the work we do to regulate our emotions on the job. Hochschild's go-to example is the flight attendant, who is tasked with being "nicer than natural" to enhance the customer experience. While at work, flight attendants are expected to smile and be exceedingly helpful even if they are wrestling with personal issues, the passengers are rude, and that one kid just upchucked down the center aisle. Hochschild's counterpart to the flight attendant is the bill collector, who must instead be "nastier than natural."</p><p>Such personas may serve an organization's mission or commercial interests, but if they cause emotional dissonance, they can potentially lead to high emotional costs for the employee—bringing us back to deep and surface acting.</p><p>Deep acting is the process by which people modify their emotions to match their expected role. Deep actors still encounter the negative emotions, but they devise ways to <a href="http://www.selfinjury.bctr.cornell.edu/perch/resources/what-is-emotion-regulationsinfo-brief.pdf" target="_blank">regulate those emotions</a> and return to the desired state. Flight attendants may modify their internal state by talking through harsh emotions (say, with a coworker), focusing on life's benefits (next stop Paris!), physically expressing their desired emotion (smiling and deep breaths), or recontextualizing an inauspicious situation (not the kid's fault he got sick).</p><p>Conversely, surface acting occurs when employees display ersatz emotions to match those expected by their role. These actors are the waiters who smile despite being crushed by the stress of a dinner rush. They are the CEOs who wear a confident swagger despite feelings of inauthenticity. And they are the bouncers who must maintain a steely edge despite humming show tunes in their heart of hearts.</p><p>As we'll see in the research, surface acting can degrade our mental well-being. This deterioration can be especially true of people who must contend with negative emotions or situations inside while displaying an elated mood outside. Hochschild argues such emotional labor can lead to exhaustion and self-estrangement—that is, surface actors erect a bulwark against anger, fear, and stress, but that disconnect estranges them from the emotions that allow them to connect with others and live fulfilling lives.</p>
Don't fake it till you make it<p>Most studies on emotional labor have focused on customer service for the obvious reason that such jobs prescribe emotional states—service with a smile or, if you're in the bouncing business, a scowl. But <a href="https://eller.arizona.edu/people/allison-s-gabriel" target="_blank">Allison Gabriel</a>, associate professor of management and organizations at the University of Arizona's Eller College of Management, wanted to explore how employees used emotional labor strategies in their intra-office interactions and which strategies proved most beneficial.</p><p>"What we wanted to know is whether people choose to engage in emotion regulation when interacting with their co-workers, why they choose to regulate their emotions if there is no formal rule requiring them to do so, and what benefits, if any, they get out of this effort," Gabriel said in <a href="https://www.sciencedaily.com/releases/2020/01/200117162703.htm" target="_blank">a press release</a>.</p><p>Across three studies, she and her colleagues surveyed more than 2,500 full-time employees on their emotional regulation with coworkers. The survey asked participants to agree or disagree with statements such as "I try to experience the emotions that I show to my coworkers" or "I fake a good mood when interacting with my coworkers." Other statements gauged the outcomes of such strategies—for example, "I feel emotionally drained at work." Participants were drawn from industries as varied as education, engineering, and financial services.</p><p>The results, <a href="https://psycnet.apa.org/doiLanding?doi=10.1037%2Fapl0000473" target="_blank" rel="noopener noreferrer">published in the Journal of Applied Psychology</a>, revealed four different emotional strategies. "Deep actors" engaged in high levels of deep acting; "low actors" leaned more heavily on surface acting. Meanwhile, "non-actors" engaged in negligible amounts of emotional labor, while "regulators" switched between both. The survey also revealed two drivers for such strategies: prosocial and impression management motives. The former aimed to cultivate positive relationships, the latter to present a positive front.</p><p>The researchers found deep actors were driven by prosocial motives and enjoyed advantages from their strategy of choice. These actors reported lower levels of fatigue, fewer feelings of inauthenticity, improved coworker trust, and advanced progress toward career goals. </p><p>As Gabriel told <a href="https://www.psypost.org/2021/01/new-psychology-research-suggests-deep-acting-can-reduce-fatigue-and-improve-your-work-life-59081" target="_blank" rel="noopener noreferrer">PsyPost in an interview</a>: "So, it's a win-win-win in terms of feeling good, performing well, and having positive coworker interactions."</p><p>Non-actors did not report the emotional exhaustion of their low-actor peers, but they also didn't enjoy the social gains of the deep actors. Finally, the regulators showed that the flip-flopping between surface and deep acting drained emotional reserves and strained office relationships.</p><p>"I think the 'fake it until you make it' idea suggests a survival tactic at work," Gabriel noted. "Maybe plastering on a smile to simply get out of an interaction is easier in the short run, but long term, it will undermine efforts to improve your health and the relationships you have at work. </p><p>"It all boils down to, 'Let's be nice to each other.' Not only will people feel better, but people's performance and social relationships can also improve."</p>

Even during anonymous studies, participants may select socially acceptable answers over honest ones. They may further interpret their goal progress and coworker interactions more favorably than is accurate. And certain work conditions may not produce the same effects, such as toxic work environments or those that require employees to project negative emotions.</p><p>There also remains the question of the causal mechanism. If surface acting—or switching between surface and deep acting—is more mentally taxing than genuinely feeling an emotion, then what physiological process causes this fatigue? <a href="https://www.frontiersin.org/articles/10.3389/fnhum.2019.00151/full" target="_blank">One study published in the <em>Frontiers in Human Neuroscience</em></a><em> </em>measured hemoglobin density in participants' brains using an fNIRS while they expressed emotions facially. The researchers found no significant difference in energy consumed in the prefrontal cortex by those asked to deep act or surface act (though, this study too is limited by a lack of real-life task).<br></p><p>With that said, Gabriel's studies reinforce much of the current research on emotional labor. <a href="https://journals.sagepub.com/doi/abs/10.1177/2041386611417746" target="_blank">A 2011 meta-analysis</a> found that "discordant emotional labor states" (read: surface acting) were associated with harmful effects on well-being and performance. The analysis found no such consequences for deep acting. <a href="https://doi.apa.org/doiLanding?doi=10.1037%2Fa0022876" target="_blank" rel="noopener noreferrer">Another meta-analysis</a> found an association between surface acting and impaired well-being, job attitudes, and performance outcomes. Conversely, deep acting was associated with improved emotional performance.</p><p>So, although there's still much to learn on the emotional labor front, it seems Van Dyke's advice to a Leigh was half correct. We should put on a happy face, but it will <a href="https://bigthink.com/design-for-good/everything-you-should-know-about-happiness-in-one-infographic" target="_self">only help if we can feel it</a>.</p>
