Yes. To some extent, it is quite possible. What we have adopted for the Darlington refurbishment program in partnership with OPG is to create a full-scale reactor mock-up. This decision was made based on the lessons learned from the Bruce refurbishment and the New Brunswick Power refurbishment that using the tool at the reactor phase and getting the buy-ins from the people using it is absolutely important.
We fabricated a full-scale reactor mock-up at Darlington, and also provided the 200 tools to our tradespeople to try on this mock-up, and then have a full plastic rehearsal, not just one time but many times, to gain the necessary proficiency in using the tools to get the full buy-ins.
For any mission-critical project like this, if we adopt the same philosophy of creating a mock-up and then training the people who will be working on the reactor, it will improve not only the safety but also the productivity. I will give you an example. The cost of producing this mock-up is equivalent to 13 days of savings in critical path activities. If, through the mock-up, we can improve our efficiency by 13 days, it has paid for itself, so it's an absolutely important aspect that can be used.
