Walls, roof collapse at Chornobyl nuclear power plant

At 2 p.m. on Feb. 12, part of the roof and the wall of the Chornobyl nuclear plant collapsed, Ukraine's emergencies services announced. The accident took down about 600 square meters of a covering adjacent to the ill-famed fourth unit. Emergencies services said radiation levels did not increase after the accident. Ukrainian officials said the preliminary cause for the collapse was heavy snowfall. Meanwhile, the plant’s administration gave itself two weeks to investigate the accident.

According to Chornobyl’s spokeswoman Maya Rudenko, normally snow is cleaned from the plant’s roof. However, she wouldn’t say if the snow was properly removed in the days before the accident, but noted that there were constant snowfalls and rain in recent days.

The collapsed area was in a machinery hall, part of plant's fourth unit, the one that exploded in 1986, spewing radiation over a large part of Europe. According to Rudenko, the collapsed area is over 50 meters away from exact place of explosion. The damaged building was part of a protective construction built after the catastrophe. While the sarcophagus covers the reactor itself, other protective structures are built around the entire unit. “We knew that there was a risk of collapsing of the old constructions,” Rudenko told Kyiv Post.

The constructing of the new shelter that will cover Chornobyl's fourth unit is scheduled for completion for 2015. The collapsed area will be covered by it, too.

3. Going to happen eventually.

That thing just wasn't designed or built well enough to last.

4. none of them are designed to last long enough to handle this sort of disaster.

5. This wasn't part of the original construction

It's not the "sarcophagus", but it is part of the hastily-built covering for other parts of the plant that was just slapped together in the wake of the original accident.

6. Right, it was jury rigged because it had to be

because the original design, as are all reactors, was under-designed for the disaster scenarios that supposedly could not happen, as actually designing and building reactors that could safely malfunction and self contain their spew for the time periods required would be ridiculously expensive.

7. Just like all commercial aircraft are underdesigned

for the disaster scenarios that supposedly can't happen. It would be ridiculously expensive to design aircraft that were actually safe, and the technology is just as dangerous as it was 60 years ago.

Aviation disasters 1946-present (tilt 20º counterclockwise to simulate bias of anti-nuclear hysteria).

10. Sorry... that's wrong.

There are substantial differences between the soviet reactor design and western reactors. What could (and did) happen there is very different from what could happen here.

And the latest designs most certainly can "safely malfunction and self contain their spew for the time periods required".

8. Tobacco contains 1,000x as much radioactivity as Chernobyl fallout

"When the Chernobyl nuclear reactor melted down in 1986, it spread radioactive fallout across a wide area. But a new study says that the amount of radioactive material left on plants by Chernobyl pales in comparison with the radium and polonium found naturally in tobacco, ITWire reported June 7.

Greek researcher Constantin Papastefanou found that tobacco plants contain up to 1,000 times more radioactive radium and polonium than the radioactive cesium fallout from Chernobyl left on plants. Polonium is considered one of the most deadly radioactive elements known to man, but is only harmful when inhaled or ingested.

“Many scientists believe that cancer deaths among smokers are due to the radioactive content of tobacco leaves and not to nicotine and tar,” according to Papastefanou, a researcher at the Atomic and Nuclear Physics Laboratory at the Aristotle University of Thessaloniki."
