That's a good question, and post-Fukushima we decided that we would look at what the industry in Canada is calling the “Binder's doomsday scenario”, which is that we don't care how we got into the doomsday scenario but that what we want to know is how we're going to mitigate the disaster.
That means, for example, that one of the important new enhancements in safety is that the industry is now talking about putting assets outside the site. So if you recall, in Japan what happened was it took them a long time to bring assets into the site. So the industry in the U.S., and in fact globally, is looking into how to enhance. This is only one point. They're also having backup to backup, so they can operate with diesel, and backup to diesel, etc. All of these have now been put in our task force report, and the commission is now looking into actually implementing them.
