Mr. Thompson mentioned probabilistic risk assessments. We require them. We have a CSA standard based on IAEA guidance, so we have international guidance on this one. We also require the licensees to look at design-basis accidents. We require them to look beyond design basis or severe accidents. We want to make sure that those are dealt with, so that they understand what they could do to prevent releases even on low-probability accidents.
How we would manage the risk would not change whether we are administering this act or not. We put a lot of effort into making sure that the risks of a major accident are kept small. We don't keep within the design basis; we go well beyond it and make sure they are controlling the risks and trying to improve the performance of the plants.
