It's absolutely correct, Mr. Chair, that we recently put staff on site because of the significant regulatory oversight issues that we have had on that site. So it actually was a response to the ongoing difficult, complex regulatory oversight needed at that site.
When the licence is given, the commission and the commission staff have the expectation that the licensee actually will put in those processes themselves to make sure that things are in place. The AECL absolutely told the commission on at least three occasions that the EPS system, as one of the seven upgrades, was in existence.
So first of all, the responsibility for ensuring the safety of that site is primarily AECL's. The CNSC staff would have had an inspection program, and in fact it was the CNSC staff who, on November 5, as pointed out in my chronology, actually pointed out the issue. That was during an arrangement for an inspection. So in fact the CNSC have had an inspection. One lesson learned, which I talked about, would in fact be to look at this. I think every organization can learn.
