requirements on the plant being able to withstand earthquakes that are historic to the area in which the plant is located. and then puts additional margin on that to make sure that that determination is conservative. the nuclear regulatory commission has indicated they're going to look again at those standards and make sure if some additional requirements may need to be placed. but that plant is well maintained. there are stringent requirements on it. it has been considerably updated since it was first built. >> so you basically don't have any concerns about radiation leaking should there be some significant earthquake in the area? >> well, my view is that the plant has been built to withstand the standards of earthquakes that could be expected in that area. one of the things you have to think about with earthquakes isn't just merely the magnitude, it's the ground motion. how much does the ground go back and forth. i think the standards the nrc has used is conservative and are appropriate for that plant, but
