The San Jose Mercury News ran an Associated Press article today:
Inspectors are waiting for the 105 degree temperature inside a nuclear reactor to drop enough to make it safe for workers and equipment to get inside and inspect a tube leak that prompted operators to shut down a nuclear plant on the California coast, officials say.
Edison spokeswoman Jennifer Manfre said Friday that the temperature inside Unit 3 would not drop to cool enough temperatures until the middle of next week.
The article contained this assessment of the steam tube damage:
According to the Nuclear Regulatory Commission, more than a third of the wall had been worn away in two tubes at Unit 2, which will require them to be plugged and taken out of service. At least 20 percent of the tube wall was worn away in 69 other tubes, and in more than 800, the thinning was at least 10 percent. The inspection is continuing.
Edison spokeswoman Manfree could not estimate when either reactor would be up and running:
With the extent of the problem unknown, it’s too soon to estimate the cost of repairs or predict when Unit 3 will resume generating power, she added.
