Nuclear disaster at Three Mile Island
At 4 a.m. on March 28, 1979, the worst accident in the history of the U.S. nuclear power industry begins when a pressure valve in the Unit-2 reactor at Three Mile Island fails to close. Cooling water, contaminated with radiation, drained from the open valve into adjoining buildings, and the core began to dangerously overheat.
The Three Mile Island nuclear power plant was built in 1974 on a sandbar on Pennsylvania’s Susquehanna River, just 10 miles downstream from the state capitol in Harrisburg. In 1978, a second state-of-the-art reactor began operating on Three Mile Island, which was lauded for generating affordable and reliable energy in a time of energy crises.
After the cooling water began to drain out of the broken pressure valve on the morning of March 28, 1979, emergency cooling pumps automatically went into operation. Left alone, these safety devices would have prevented the development of a larger crisis. However, human operators in the control room misread confusing and contradictory readings and shut off the emergency water system. The reactor was also shut down, but residual heat from the fission process was still being released. By early morning, the core had heated to over 4,000 degrees, just 1,000 degrees short of meltdown. In the meltdown scenario, the core melts, and deadly radiation drifts across the countryside, fatally sickening a potentially great number of people.
As the plant operators struggled to understand what had happened, the contaminated water was releasing radioactive gases throughout the plant. The radiation levels, though not immediately life-threatening, were dangerous, and the core cooked further as the contaminated water was contained and precautions were taken to protect the operators. Shortly after 8 a.m., word of the accident leaked to the outside world. The plant’s parent company, Metropolitan Edison, downplayed the crisis and claimed that no radiation had been detected off plant grounds, but the same day inspectors detected slightly increased levels of radiation nearby as a result of the contaminated water leak. Pennsylvania Governor Dick Thornburgh considered calling an evacuation.
Finally, at about 8 p.m., plant operators realized they needed to get water moving through the core again and restarted the pumps. The temperature began to drop, and pressure in the reactor was reduced. The reactor had come within less than an hour of a complete meltdown. More than half the core was destroyed or molten, but it had not broken its protective shell, and no radiation was escaping. The crisis was apparently over.
Two days later, however, on March 30, a bubble of highly flammable hydrogen gas was discovered within the reactor building. The bubble of gas was created two days before when exposed core materials reacted with super-heated steam. On March 28, some of this gas had exploded, releasing a small amount of radiation into the atmosphere. At that time, plant operators had not registered the explosion, which sounded like a ventilation door closing. After the radiation leak was discovered on March 30, residents were advised to stay indoors. Experts were uncertain if the hydrogen bubble would create further meltdown or possibly a giant explosion, and as a precaution Governor Thornburgh advised “pregnant women and pre-school age children to leave the area within a five-mile radius of the Three Mile Island facility until further notice.” This led to the panic the governor had hoped to avoid; within days, more than 100,000 people had fled surrounding towns.
On April 1, President Jimmy Carter arrived at Three Mile Island to inspect the plant. Carter, a trained nuclear engineer, had helped dismantle a damaged Canadian nuclear reactor while serving in the U.S. Navy. His visit achieved its aim of calming local residents and the nation. That afternoon, experts agreed that the hydrogen bubble was not in danger of exploding. Slowly, the hydrogen was bled from the system as the reactor cooled.
At the height of the crisis, plant workers were exposed to unhealthy levels of radiation, but no one outside Three Mile Island had their health adversely affected by the accident. Nonetheless, the incident greatly eroded the public’s faith in nuclear power. The unharmed Unit-1 reactor at Three Mile Island, which was shut down during the crisis, did not resume operation until 1985. Cleanup continued on Unit-2 until 1990, but it was too damaged to be rendered usable again.
U.S. PRESIDENTS
1969
President Eisenhower dies
Dwight D. Eisenhower, the 34th president of the United States and one of the most highly regarded American generals of World War II, dies in Washington, D.C., at the age of 78. Born in Denison, Texas, in 1890, Eisenhower graduated from the United States Military Academy in 1915, and after World War I he steadily rose in the peacetime ranks of the U.S. Army. After the U.S. entrance into World War II, he was appointed commanding general of the European theater of operations and oversaw U.S. troops massing in Great Britain. In 1942, Eisenhower, who had never commanded troops in the field, was put in charge of Operation Torch, the Anglo-American landings in Morocco and Algeria.
HISPANIC HISTORY
1939
Spanish Civil War ends
In Spain, the Republican defenders of Madrid raise the white flag over the city, bringing to an end the bloody three-year Spanish Civil War. In 1931, Spanish King Alfonso XIII approved elections to decide the government of Spain, and voters overwhelmingly chose to abolish the the monarchy in favor of a liberal republic. Alfonso subsequently went into exile, and the Second Republic, initially dominated by middle-class liberals and moderate socialists, was proclaimed. During the first five years of the Republic, organized labor and leftist radicals forced widespread liberal reforms, and the independence-minded Spanish regions of Catalonia and the Basque provinces achieved virtual autonomy.
ART, LITERATURE, AND FILM HISTORY
1958
W.C. Handy—the “Father of the Blues”—dies
“With all their differences, my forebears had one thing in common: if they had any musical talent, it remained buried.” So wrote William Christopher Handy in his autobiography in discussing the absence of music in his home life as a child. Born in northern Alabama in 1873, Handy was raised in a middle-class African American family that intended for him a career in the church. To them and to his teachers, W.C. Handy wrote, “Becoming a musician would be like selling my soul to the devil.” It was a risk that the young Handy decided to take. He was internationally famous by the time he wrote his 1941 memoir, Father of the Blues, although “Stepfather” might have been a more accurate label for the role he played in bringing Blues into the musical mainstream. The significance of his role is not to be underestimated, however. W.C. Handy, one of the most important figures in 20th-century American popular music history, died in New York City on March 28, 1958.
WORLD WAR I
1915
First American citizen killed during WWI
On March 28, 1915, the first American citizen is killed in the eight-month-old European conflict that would become known as the First World War. Leon Thrasher, a 31-year-old mining engineer and native of Massachusetts, drowned when a German submarine, the U-28, torpedoed the cargo-passenger ship Falaba, on its way from Liverpool to West Africa, off the coast of England. Of the 242 passengers and crew on board the Falaba, 104 drowned. Thrasher, who was employed on the Gold Coast in British West Africa, was returning to his post there from England as a passenger on the ship.
SPORTS
1984
Baltimore Colts move to Indianapolis
On March 28, 1984, Bob Irsay (1923-1997), owner of the once-mighty Baltimore Colts, moves the team to Indianapolis. Without any sort of public announcement, Irsay hired movers to pack up the team’s offices in Owings Mills, Maryland, in the middle of the night, while the city of Baltimore slept. Robert Irsay gained control of the Colts in 1972 when he essentially traded his ownership in the Los Angeles Rams with Caroll Rosenbloom, then the owner of the Colts franchise. The Colts, led by quarterback Johnny Unitas, halfback Lenny Moore and defensive linemen Gino Marchetti and Art Donovan, had been the best team in the NFL in the late 1950s and had come to embody the working-class spirit of Baltimore. The players lived among the fans, worked alongside the fans in the off-season and performed with evident pride in their adopted city. It wasn’t until Irsay purchased the team that the franchise began its downward spiral. After winning Super Bowl V in 1971, the Colts had a few winning years, but by the late 1970s, the franchise was so bad that when future Hall of Fame quarterback John Elway was drafted number one overall by the Colts out of Stanford in 1983, he refused to report to the team, saying he would play baseball for the New York Yankees instead. The Colts were forced to trade Elway to the Denver Broncos.
U.S. PRESIDENTS
1834
Congress censures President Jackson
On March 28, 1834, President Andrew Jackson is censured by Congress for refusing to turn over documents. Jackson was the first president to suffer this formal disapproval from Congress. During his first term, Jackson decided to dismantle the Bank of the United States and find a friendlier source of funds for his western expansion plans. Jackson, who embodied the popular image of the Wild West frontiersman, claimed that the bank had too many foreign investors, favored the rich over the poor and resisted lending funds to develop commercial interests in America’s Western territories. When the Senate passed legislation in 1831 to renew the bank’s charter, Jackson promptly vetoed it. An 1831 meeting with his cabinet generated classified documents regarding Jackson’s veto of the bank legislation. Soon after, Congress overruled Jackson’s veto.
CRIME
1814
Funeral held for the man behind the guillotine
The funeral of Dr. Joseph-Ignace Guillotin, the namesake of the infamous execution device, takes place outside of Paris, France. Guillotin had what he felt were the purest motives for inventing the guillotine and was deeply distressed at how his reputation had become besmirched in the aftermath. Guillotin had bestowed the deadly contraption on the French as a “philanthropic gesture” for the systematic criminal justice reform that was taking place in 1789. The machine was intended to show the intellectual and social progress of the French Revolution; by killing aristocrats and journeymen the same way, equality in death was ensured.
CRIME
2006
Duke lacrosse team suspended following sexual assault allegations
Duke University officials suspend the men’s lacrosse team for two games following allegations that team members sexually assaulted a stripper hired to perform at a party. Three players were later charged with rape. The case became a national scandal, impacted by issues of race, politics and class. In April 2007, all charges against the young men were dropped due to lack of credible evidence and the district attorney was eventually disbarred for his mishandling of the case.
CIVIL WAR
1862
Union forces halt Confederates at Battle of Glorieta Pass
On March 28, 1862, Union forces stop the Confederate invasion of New Mexico Territory when they turn the Rebels back at Glorieta Pass. This action was part of the broader movement by the Confederates to capture New Mexico and other parts of the West. This would secure territory that the Rebels thought was rightfully theirs but had been denied them by political compromises made before the Civil War. Furthermore, the cash-strapped Confederacy could use Western mines to fillits treasury. From San Antonio, the Rebels moved into southern New Mexico (which included Arizona at the time) and captured the towns of Mesilla, Díaz Ana and Tucson. General Henry H. Sibley, with 3,000 troops, now moved north against the Federal stronghold at Fort Craig on the Rio Grande.
AMERICAN REVOLUTION
1774
British Parliament adopts the Coercive Acts in response to the Boston Tea Party
Upset by the Boston Tea Party and other blatant acts of destruction of British property by American colonists, the British Parliament enacts the Coercive Acts, to the outrage of American Patriots, on March 28, 1774. The Coercive Acts were a series of four acts established by the British government. The aim of the legislation was to restore order in Massachusetts and punish Bostonians for their Tea Party, in which members of the revolutionary-minded Sons of Liberty boarded three British tea ships in Boston Harbor and dumped 342 crates of tea—nearly $1 million worth in today’s money—into the water to protest the Tea Act.
