Footnotes
1Seismic level 1 and seismic level 2 (SL-1 and SL-2) are levels of ground motion (representing the potential effects of earthquakes) considered in the design basis for a facility. SL-1 corresponds to a less severe, more likely earthquake than SL-2. In some States, SL-1 corresponds to a level with a probability of 10–2 per year of being exceeded, and SL-2 corresponds to a level with a probability of 10–4 per year of being exceeded.
