Chernobyl after thirty years
Thirty years ago, the staff running a test on reactor #4 at the Lenin Nuclear Power Plant near Pripyat, Ukraine, USSR were reading unexpectedly high radiation levels. They debated stopping the test, but decided to keep going to find the limits. When the temperature readings climbed too high as well, they tried to shut the reactor down by inserting carbon rods.
There was, however, a design flaw, known by upper levels in the government, but not by the staff doing the testing. Inserting those rods somehow increased the reaction, increasing the heat. Containment water became steam, the roof of the reactor blew off and some ten tons of radioactive uranium became airborne, and was carried southeast, contaminating a large swath of Europe.
McClatchy has a very good article, Ruined Chernobyl nuclear plant will remain a threat for 3,000 years, in which they actually mention other nuclear accidents:
What they figured out was the worst nuclear-energy disaster in human history, far worse than the explosion at Kyshtym nuclear complex in 1957 in what was then the Soviet Union, which released 70 tons of radioactive material into the air, or the 1957 fire at the Windscale Nuclear Reactor in northwestern England, which forced a ban on milk sales for a month, or the Three Mile Island disaster in Pennsylvania on March 29, 1979, where a cooling malfunction led to a partial meltdown.
There are also persistent leaks threatening groundwater at Hanford in the US, and the ongoing Fukushima disaster in Japan.
CNN tries to consign the radiation problems to history, offering more upbeat articles about Chernobyl. In Meet the New Face of Chernobyl they focus on fetching young Yulia, who lives in a nearby community, Slavutych, and was chronicled over three years by Swiss photographer Neils Ackermann:
Ackermann isn’t interested in making you sit through another telling of that tragic tale about the firefighters who couldn’t put out the flames in 1986, or the technicians who failed to stop the poisonous radioactive particles from escaping the facility and raining down on nearby residents.
Instead, he wants to introduce you to Yulia.
“She’s intense, like an energy bomb,” Ackermann said, describing the 23-year-old woman he met in 2012. At the time, Yulia was kissing a man in a park in the center of Slavutych, a town near Chernobyl built for disaster evacuees.
Yulia was born three years after the disaster. Ackermann once asked her what she thought about its consequences. “She was looking at me like it was a really stupid question,” he recalled. “Because now, the scale of health consequences resulting from radioactivity in Slavutych are much more limited than what we may think about in the West.” Slavutych residents who work in Chernobyl are protected by strict control systems. The town’s attitude about radioactivity is much more realistic and pragmatic than it would be elsewhere. One young man showed Ackermann the tomb of his best friend in a cemetery and said more people in town die because of drugs and alcohol than radioactivity.
In another article, CNN emphasizes the precautions taken as Ukraine builds a new arched structure over the decrepit sarcophagus that was built quickly after the explosion. This New Safe Confinement structure is supposed to last at least one hundred years, but the buried mass will be a threat for at least three thousand years, so I wonder who will build the next thirty structures?
