Dear Dr. Jackson:
i The. purpose of this letter is to provide you with results of our limited analysis for the Seabrook site that you requested some -
time ago. We developed the enclosed estimate of the seismic .
hazard for the'Scabrook site in the same manner that we developed the seismic hazard for the sites involved in the Systematic
{
Evaluation Program (SEP). We have used the model recommen,ded by NRC and described in Jackson (1980) to specify the hazard for the sites-located in New England, t Figure 1 shows the results (synthesis) compared to R.G. 1.60
} scaled to 0.25g (245.4cm/S2) for 5% damping. The data used to construct this figure are given in Table 1.
4 I hope that this is sufficient information however, if not, 3 feel free.to call me and I will be happy to supply you with any additional information you might need.
Sincerely,
./ '7n Don L. Bernreuter, Leader
