running US and Japanese nuclear power plants. I'd say the Californians have damned good reasons to be concerned.
The failure of emergency systems at Japan's nuclear plants comes as no surprise to those of us who have worked in the field.
Nuclear plants the world over must be certified for what is called "SQ" or "Seismic Qualification." That is, the owners swear that all components are designed for the maximum conceivable shaking event, be it from an earthquake or an exploding Christmas card from al-Qaeda.
The most inexpensive way to meet your SQ is to lie. The industry does it all the time. The government team I worked with caught them once, in 1988, at the Shoreham plant in New York. Correcting the SQ problem at Shoreham would have cost a cool billion, so engineers were told to change the tests from "failed" to "passed."
The company that put in the false safety report? Stone & Webster, now the nuclear unit of Shaw Construction, which will work with TEPCO to build the Texas plant. Lord help us.

Back in the day, when we checked the emergency backup diesels in America, a mind-blowing number flunked. At the New York nuclear plant, for example, the builders swore under oath that their three diesel engines were ready for an emergency. They'd been tested. The tests were faked; the diesels run for just a short time at low speed. When the diesels were put through a real test under emergency-like conditions, the crankshaft on the first one snapped in about an hour, then the second and third. We nicknamed the diesels, "Snap, Crackle and Pop."
