Thousands of brittle tubes. Seems like a bad plan.
The Nuclear Regulatory Commission said Thursday it was sending a special team of inspectors to try to determine why the metal tubes, which were installed in Unit 3 in 2010, have become frail enough to pose a risk of leaks.
“This is a significant issue,” said NRC spokeswoman Lara Uselding. “A tube rupture is really the concern.”
Investigators have been looking into excessive wear on tubes in Unit 3 and its twin, Unit 2, which has been off line for maintenance and refueling. In a $670 million overhaul, two huge steam generators, each containing 9,700 tubes, were replaced in Unit 2 in fall 2009 and a year later in Unit 3.
