The reactor, in fact, had been shut down earlier than scheduled to compensate for that leak. But the Canadian public was told about “unanticipated technical challenges”.
I will pose this question to AECL. I was trying to get some understanding from you, as an expert in the field, if that is somehow code or translates into a serious problem. While you may suggest that the site is big and there are miles of pipe, the funny thing about nuclear waste is that it doesn't take much to affect an environment, and it doesn't take much to alert the public.
Is it leaking right now?
