May 8: This is supposed to be the R4 spent fuel pool. Why is the top of the reactor visible in the spent fuel pool? Easy. it's not the spent fuel pool. it's the reactor reloading pool. That's why the top of the reactor is visible at the beginning of the picture. The spent fuel pool would have been two floors above this. I'll bet it doesn't look like this anymore – and I hope everyone within a thousand miles of this is moving away as we speak.
