Taking the nukes first, it certainly is not news that utilities all across the United States including Xcel Energy in Minnesota have sought federal approval for programs to refurbish nuclear reactors as they come to the end of their operating licenses and then to have those licenses renewed.Still, it was striking to read in Sunday’s Times that officials in charge of seven plants in Pennsylvania, Virginia and South Carolina "are preparing to ask for permission to run them until they are 80 years old."Working past retirement ageThe plants, that is, would be 80 years old; the utility executives will have retired at a much younger age. In terms of total design lifespan,
TaylorMade R15 Hybrid, the Times noted, the extensions could mean that certain plants would be running on plans drawn 90 or even 100 years earlier.Back in the 1990s, when the idea of getting 20 year license extensions for 40 year old reactors was gaining traction, it may have seemed like a sensible short term fix in an era when electricity demand was rising steeply and steadily,
Titleist 915 D3 Driver, the chances of putting a new nuke plant on line were tiny, and the writing was on the wall, however faintly, about the need to phase out coal fired generation.Since setting the rules for relicensing in 1991, the Times reports,
Titleist 915 D2 Driver, the Nuclear Regulatory Commission has granted 70 license extensions and rejected none.Now it has to figure out how to handle expected applications for additional 20 year extensions that it anticipates will go on the docket starting about four years from now.I don’t know about you, but I didn’t find terribly comforting to be reminded that, "To win a license extension, the plants do not have to show that they will be safe for 80 years, only that they have monitoring programs in place to promptly detect problems as they emerge."Exposed to decades of radiation, some metal parts grow brittle and more likely to crack under stress. One potential source of stress is the emergency core cooling system; if the system sensed a leak in the piping, it could start up and dump huge volumes of cold water into a reactor, keeping it at operating pressure but at a far lower temperature.
