You: Why Dave; why now?
Me: Well, I've a two talented kids; the younger said, 'Stop with the lectures.' Then asked, 'Dad, can I help you set up a blog?' Moments later, Me: 'OK, that's a great idea, thinkin' they might just read it someday.

Science, Environment, MIT Looking at a few of the pictures, it is very likely that some concrete failure was involved in the mishap. How high up in the chain of causation is a matter to be determined, or not, depending on the honesty and competency of the Russians. The disaster is an environmental tragedy where 400 tons of trout were killed by the transformer oil (with presumed deadly dioxins) that was released with the explosions caused by the water shorting the transformers and generators. Creating better concrete for uses such as hydroelectric which depend on that structure for as long as it functions and if failure occurs, this type of disaster is the result. This may alter the cost-benefit ratio as regards lifecycle of such a power facility. Similar disaster almost occurred during Hur. Andrew in 1992 when the emergency power was flooded out within the plant so that the cooling pumps stopped as did the controlling mechanisms. Luckily the storm was fast moving at about 25 mph, so the emergency power was restored before the cooling system ruptured and all hell would have broken loose, but differently from Chernobyl which was a dry system using graphite blocking radiation and no water. Trying to calculate catastrophic failure is difficult to be accurate as it happens so infrequently. Studying this Russian one would be very important as any improvement to the failed components would enhance it’s benefit of lifecycle. Critically failed components would be most important to identify. That’s critical when that component fails, the system fails. Remember as my last comment to FEMA as a Hazard Mitigation Specialist: Mitigation is like good sex: you have got to harden the worst first.The Sayano-Shushenskaya dam accident - The Big Picture - Boston.com
On August 17th, near Sayanogorsk in south central Russia, a catastrophic accident took place in the turbine and transformer rooms of the hydroelectric plant of the Sayano-Shushenskaya dam. The exact cause is still under investigation, but what is known so far is that a tremendous amount of water from the Yenisei River flooded the turbine room, causing at least one transformer explosion and extensive damage to all ten turbines, destroying at least three of them. 74 workers are known to have lost their lives in the accident, while one remains missing. Additionally, 40 tons of transformer oil were spilled into the river, killing an estimated 400 tons of trout in two fisheries. Investigators plan to release findings in two months, as Prime Minister Vladimir Putin called for a nationwide infrastructure inspection. (32 photos total)
