Mr. Chair, the 120 days is a rough approximation of the time at risk argument that was added to the safety case. Essentially, what time at risk means is that the risk is acceptable for a period of time. That is roughly where it came from.
In order for pump four to return to normal isotope production, the installation of the upgrade would need to be done during those four day outages on a monthly basis. That will represent a challenge for us. I do not want to mislead the member or Parliament. That will be a challenge for us, but it is an achievable outcome.
