Note 1: EPRI and LLNL values shown are median, mean, 85 percent respectively

Note 2: Number shown is EPRI value x correction factor due to lack of LLNL

measurable value

Note 3: LLNL results for these fractiles and probabilities were above values

provided by site contractor.

Note 4: TERA values for Oak Ridge and Portsmouth assumed soil site

conditions while LLNL and EPRI values assumed rock site conditions. Lawrence

Livermore National Laboratory personnel believe that for peak acceleration the

original TERA values for soil would be the same as if rock has been assumed,

thus making comparison consistent.

Note 5: The Princeton site does not have LLNL results available without LLNL-

AE5 and does not have available EPRI results. Value recommended is based

on LLNL, peak acceleration with LLNL-AE5 divided by 1.2, times the correction

factor.

Note 6: The Brookhaven site does not have EPRI results available. Value

recommended is based on LLNL peak acceleration without LLNL-AE5 times the

correction factor.

Note 7: The correction factor is 1.80 for probabilities more than or equal to 1 x

10E-3 and 1.65 for the probability of 2 x 10E-4.
