On December 2, 1942, a small group of physicists under the direction of Enrico Fermi gathered on an old squash court beneath Alonzo Stagg Stadium on the Campus of the University of Chicago to make and witness history. Uranium pellets and graphite blocks had been stacked around cadmium-coated rods as part of an experiment crucial to the Manhattan Project–the program tasked with building an atom bomb for the allied forces in WWII.

Yes, it’s time for that metaphor again. If you grew up near a TV during the 1960s or ’70s, you probably remember the ever-burning Yule Log that took the place of programming for a large portion of Christmas Day. The fire burned, it seemed, perpetually, never appearing to consume the log, never dimming, and never, as best the kid who stared at the television could tell, ever repeating.

The Nuclear Regulatory Commission cannot issue a license for the construction and operation of a new nuclear reactor in Maryland–that is the ruling of the NRC’s Atomic Safety and Licensing Board (ASLB) handed down Thursday.
Michael Mariotte, Executive director of NIRS, called Thursday’s decision “a blow to the so-called ‘nuclear renaissance,’” noting that back in 2007, when permit requests were submitted for Calvert Cliffs 3, the project was considered the “flagship” of a coming fleet of new reactors. “Now,” said Mariotte, “it is a symbol or the deservedly failed revival of nuclear power in the US.”
A symbol, yes, but far from the only symbol.

The real profits in the nuclear racket come from the ability to collect on services not rendered and a product not delivered, or at least not delivered regularly. Because the system backstops the financing of nuclear facilities while also allowing plant operators to pass both real and anticipated costs onto ratepayers, many American taxpayers are poised to pay twice for nuclear power plants that don’t produce power.

For those who thought that, with the new year, nuclear power had turned a page and put its “annus horribilis” behind it–as if the calendar were somehow the friend America’s aging reactors–let’s take a quick look at January 2012.

Gregory Jaczko, the chairman of the United States Nuclear Regulatory Commission, made some comments to the press earlier this week. Jaczko, it seems, is worried. He believes, as noted in an Associated Press story, that “U.S. nuclear plant operators have become complacent, just nine months after the nuclear disaster in Japan.” The NRC head thinks that a slew of events at over a dozen domestic nuclear facilities reveal the safety of America’s reactors to be something less than optimal.
To be clear, safety concerns at any kind of plant, be it a soda bottler or a microchip manufacturer, are probably not trivial, but when the safe and secure operation of a nuclear facility comes into question–as the aftermath of Chernobyl or the ongoing crisis in Japan will tell you–it ratchets up concern to a whole different level. So, when the man who more or less serves as the chief safety officer for the entirety of the nation’s nuclear infrastructure says he’s worried, many, many other people should be worried, too.

As September drew to a close, residents of southwest Michigan found themselves taking in a little extra tritium, thanks to their daily habit of breathing. The tritium was courtesy of the 40-year-old Palisades Nuclear Generating Station in Covert Township, which suffered its third “event” (as they are politely called) in less than two months, and was forced to vent an indeterminate amount of radioactive steam.
The reactor at Palisades was forced to scram after an accident caused an electrical arc in a transformer in the DC system that powers “indications and controls“–also known as monitoring devices, meters and safety valves.
While it is nice to see rectors shut themselves down when a vital system goes offline, remember that “turning off” a fission reactor is not like flicking a light switch. Shutting down a reactor is a process, and the faster it is done, the more strain it puts on the reactor and its safety and cooling systems. And even after fission is mitigated, a reactor core generates heat that requires a fully functional cooling system.
