Mr. Chair, within our regulatory toolbox, what we do to provide assurance of safe operation is verification work. If there is a problem, we do enforcement work if we find things out of compliance. For return to service, we would be looking at three things.
First, main heavy water pump 105 would be connected to the new emergency power system. We would be looking at the quality assurance and quality control applied for that connection, the reliability and the testing to make sure that would be done right.
For the other critical main heavy water pump 104, which would not be connected to emergency power system, we would make sure that it was serviceable, and our understanding is that AECL had not done any work on it.
The final thing would be that when a reactor is returned to service, the operator follows the routine start-up processes. We would do routine verification to make sure that this has been followed.
