50-508 APPLICANT: Washington Public Power Supply System (WPPSS)

FACILITY:

Nuclear Project 3

SUBJECT:

MEETING

SUMMARY

On August 23, 1984, NRC and applicant representatives met in Bethesda, Maryland to discuss the details of their position paper on subduction zone earthquake. A meeting notice and attendance roster are enclosed (Enclosures 1 and 2 respectively).

The applicant presented infonnation on the following items:

(i)WNP-3 situation and status, (ii) Anticipated geologic investigations of geosciences program, and (iii) characteristics of the Juan De Fuca/ North American Plate Boundary. ~he highlights of the applicant's presentation are provided in Enclosure 3.

The technical presentation was made by Dr. Greg Davis, geological consultant to WPPSS. The major open issue is whether or not there is potential for a great earthquake (magnitude 8 or greater) in the site region as a result of i

the subduction of the Juan De Fuca oceanic plate beneath the rlorth American continental plate. Available evidence supports active subduction but is insufficient to determine if it is occurring seismically or aseismically. Dr.

Davis stated that the problem was still unresolved but based on the most recent study by WPPSS, the case for aseismic slip is more strongly supportcd now than it has been in the past. The evidence on which that opinion is based 1

falls into four categories: geodecy, earthquake. fault plane solutions, comparison 1

of the geologic characteristics of the Juan De Fuca/ North American plate boundary with other plate boundaries around the globe, and comparison of the seismicity of the Juan De Fuca/ North American margin with other margins i

worldwide.

The staff was satisfied with the efforts of the applicant and provided oral comments. Detailed comments will be provided at a later date following review of the applicant's submittal.
