Chernobyl Accident Cannot Occur In U.S. Type Reactors


Twenty years ago (April 25, 1986), the Chernobyl nuclear accident sent a plume of radiation into the air above Ukraine.  The word "Chernobyl" remains the most emotionally charged argument used by the opponents of nuclear energy.  But if examined carefully, the main lesson from Chernobyl may be that what happened there cannot occur in the better designed light water reactors used in the United States, and most of the rest of the world.  William Sweet, the author of the commentary below, has also authored Kicking the Carbon Habit:  Global Warming and the Case for Renewable and Nuclear Energy.

 

(p. A23) . . . , though it went unnoticed at the time and has been inadequately appreciated since, Chernobyl also cast into relief the positive features of the reactors used in the United States and most other advanced industrial countries.

The reactor at Chernobyl belonged to a class that was especially vulnerable to runaway reactions.  When operating at low power, if such reactors lost water, their reactivity could suddenly take off and very rapidly reach a threshold beyond which they could only explode.  Making matters worse, surprisingly little more pressure than normal in the machine’s water channels would lift its lid, snapping the vital control rods and fuel channels that entered the reactor’s core.

On the night of April 25, 1986, poorly trained and supervised plant operators conducted an ill-conceived experiment, putting the machine into the very state in which reactivity was most likely to spike.  Within a fraction of a second, the reactor went from being barely on to power levels many times higher than the maximum intended.

This kind of accident cannot happen in the so-called light water reactors used in the United States and most of Western Europe and Asia.  In these reactors, the water functions not only as a coolant but as a "moderator": self-sustaining nuclear chain reactions cannot take place in its absence.  This is a very useful passive safety feature.  If coolant runs low, there is still a danger of a core meltdown, because the fuel retains heat; but the reactor will have automatically and immediately turned itself off.

The Centrally Planned Economy: “Why doesn’t Wuhan have heating?”

(p. B1) WUHAN, China — As a winter wind howled through this central Chinese city, university lecturer Li Qiao settled down in his two-bedroom apartment for what should have been a cozy evening of reading. Around his apartment were signs of China’s new prosperity: a color television, refrigerator, washing machine and air conditioner. The only thing missing: heating.
Even though winter temperatures in Wuhan dip into the 30s with occasional snow, virtually none of the city’s homes are heated. “The cold is cutting into my bones,” lamented Mr. Li, who was bundled up in a down coat and a quilt, with an electric heater blowing warm air toward him. “Why doesn’t Wuhan have heating?”
Mr. Li isn’t the only one asking. Heating systems are one of the last areas that remain under China’s former centrally planned economy, with government regulators still setting the thermostat for homes, classrooms and offices across the country. Under the policy, which dates back to Mao Zedong in the 1950s, the government provides heat in the northern half of China, and, to save money, it provides no heat in the southern half. As a result, northerners often wilt in steaming apartments, while those in southern provinces shiver through the winter.
With no heat, even residents of modern cities like Shanghai spend much of the winter trying to get warm.
. . .
(p. B2) Mr. Li, the university teacher, and his wife ward off the cold air that seeps into their apartment at the university with an electrical heater, a hot-air fan and a wall unit air-conditioner that also blows out heat. At night, they wriggle into long underwear before piling under two sets of thick quilts. Although he has a three-hour lunch break, Mr. Li seldom goes back to his apartment, opting instead to hole up in his heated office.
His students aren’t so lucky. Classrooms aren’t heated, so they listen to his lectures swathed in down jackets, caps and gloves. Some students even carry hot-water bottles to keep their hands warm and cushions to place on the icy chairs.

Hayek Was Right: Free Speech is Fragile, When Property Can be Seized


For those who doubt the central message of Hayek’s The Road to Serfdom, something to ponder:

 

(p. 351) The Sandinistas called coffee farmers who cooperated with them "patriotic producers." Anyone who questioned their politics or policies was labeled a capitalist parasite. Throughout most of the 1980s, any farms that did not produce sufficiently, or whose owners were too vocal, were confiscated by the government.

Solzhenitsyn Endures: The Return of “The First Circle”

    Source of book image:   Amazon.com.

I remember Ben Rogge recommending The First Circle, decades ago when it first appeared in English. It is a powerful, courageous, wise work, bearing many lessons. As you read the book, you keep hoping you can find someone to blame for the evil that is happening. But as Solzhenitsyn works his way up the bureaucracy, each bureaucrat has a plausible motive for his part in evil; one motive, for example, is the protection of the bureaucrat’s family. Only when you reach Stalin, do you find someone who you can really despise. But he seems borderline crazy, so even he is not a totally satisfying villian.

The book can be seen as illustrating a point that Rogge often made: socialism is not bad because it is run by bad people; it is bad because it provides ordinary people incentives to do bad things. (These are not his words, but I believe they capture his point.)


Alexandr Solzhenitsyn. Source of image: online version of the NYT article quoted and cited below.

(p. A1) MOSCOW, Feb. 8 — A grandfatherly figure, his bearded face wrinkled into a smile, peers down from billboards around town.

It is surprise enough that the man is Aleksandr I. Solzhenitsyn, the once-exiled writer, Nobel Prize winner and, of late, octogenarian scold. It is even more so that the billboards advertise his adaptation — broadcast on state television, no less — of one of his fiercely anti-Soviet novels, “The First Circle.”

Solzhenitsyn has been called the conscience of the nation, but his reputation has risen and fallen as tumultuously as Russia itself since the collapse of the Soviet Union. “First Circle” has once again placed him on the national stage, reaching an audience that would have been inconceivable to him four decades ago, when he smuggled the book out of the Soviet Union.

Private Property Rights Would Help American Indians

(p. W11) The main problem with Indian reservations isn’t, as some argue, that they were established on worthless tracts of grassland. Consider the case of Buffalo County, S.D., which Census data reveal to be America’s poorest county. Some 2,000 people live there. More than 30% of the homes are headed by women without husbands. The median household income is less than $13,000. The unemployment rate is sky high.

Just to the east of Buffalo County lies Jerauld County, which is similar in size and population. Yet only 6% of its homes are headed by women without husbands, the median household income is more than $30,000, and the unemployment rate hovers around 3%. The fundamental difference between these two counties is that the Crow Creek Indian Reservation occupies much of Buffalo County. The place is a pocket of poverty in a land of plenty.
Maybe we should give land back to the rez-dwellers, so that they may own private property the way other Americans do. Currently, the inability to put up land as collateral for personal mortgages and loans is a major obstacle to economic development. This problem is complicated by the fact that not all reservations have adopted uniform commercial codes or created court systems that are independent branches of tribal government — the sorts of devices and institutions that give confidence to investors who might have the means to fund the small businesses that are the engines of rural economies.
. . .
. . . the real tragedy is that reservations, as collectivist enclaves within a capitalist society, have beaten down their inhabitants with brute force rather than lifting them up with opportunity. As their economies have withered, other social pathologies have taken root: Indians are distressingly prone to crime, alcoholism and suicide. Families have suffered enormously. About 60% of Indian children are born out of wedlock. Although accurate statistics are hard to come by because so many arrangements are informal, Indian kids are perhaps five times as likely as white ones to live in some form of foster care. Their schools are depressingly bad.
Even if casino revenues were able to address these soul-crushing problems — a doubtful proposition — most reservations are too isolated geographically to profit from big-dollar gambling. Yet the rise of the casinos may help point the way forward: Their ability to flourish contradicts the tenured Marxists in ethnic-studies departments who claim that communitarian Indian cultures aren’t compatible with market capitalism. After all, it takes entrepreneurship to run some of the world’s biggest casinos.
What’s more, this modern-day entrepreneurship is part of a long tradition: Meriwether Lewis (of Lewis & Clark fame) described the Chinooks as “great hagglers in trade.” I once visited Poverty Point, a 3,000-year-old set of earthen mounds in Louisiana; the museum there displayed ancient artifacts found at the site, including copper from the Great Lakes and obsidian from the Rockies. These prehistoric Americans were budding globalizers, and there’s no reason why their descendants should remain walled off from the world economy.
