Yeah, add "drama queen" to nadin's resume.
Uh, nads? You want to know what happened, in terms even a drooling mouth-breather such as yourself understands?
It's called a primary to secondary leak. Not even a large one, by the looks of it. By now, the plant is shutdown, cooled down, and depressurized so the leak is not a problem. The steam generator stops are closed so nothing is leaking into the turbine building or to the outside.
More likely than not, the first indication of the leak (pinhole size at best) was due to elevated activity in the secondary samples, not some poor surfer growing a third arm. What they'll do is do a steam generator inspection after they've drained the primary down to mid-loop, find the leaking tube, plug it, make sure there aren't any others potentially leaking (either by UT or eddy current testing), refill the primary, clean up the steam generator, latch and snatch the rods, and keep on pluggin.
Your milk is safe, nads. All good. You got more radiation exposure from your tooth x-ray than you'll ever get from San Onofre, and while it's not the best run plant as far as nukes go, I'll work there over a dirt-burner every single time.
Although I will say that the boys there might not have much of a life right now, they're gonna LOVE those paychecks. Nothing like a forced outage check to remind me why I work here.
