Steam Generators: Design and details

A recent NRC blog post (see here) brings up a matter that has come into focus of late at San Onofre Nuclear Generating Station in California. The problem, briefly, is this; leaks have been detected in the steam generators at Unit 3 at the site, and Unit 2, with identical steam generators and which has been shut down for work anyway, was also inspected and the operator, Southern California Edison, has made the decision to restart neither plant until the cause of the leaks at No. 3 plant and assurance it won't happen at No. 2 plant are both secured. While No. 2 plant did have some steam generator tubes plugged as a part of normal work, and there appears to be no commonality between the few leaking tubes at No. 2 and the leaks at No. 3, SCE has decided to be cautious.
