SUBJECT:
WNP-2 GABLE MOUNTAIN FAULT ASSESSMENT On October 16 and 17, 1980, Phil Justus, accompanied by the U; S. Geological Survey, visited the kNP-2 site region and examined trench excavations at Gable Mountain.
Although he cannot prepare a trip report for several,
- weeks, due to the need to prepare for a G.E. Test Reactor subcommittee and full committee meetings, we have discussed his visit'nd decided on the following course of action in the immediate future.
I believe that we. should handle this problem as a,.HNP-2.licensing action under the ongoing OL review and that we and our USGS advisors request all necessary information through the HNP-2 docket.
This approach is absolutely. necessary in order to avoid confusion due to the ancillary involvement of NESCO (Puget/
~ Skagit site),
Department of. Energy, and various Haste Isolation Projects
. including NRC/NMSS.
7 It is our 'current understanding that the WNP-2 applicant will request through
- Harold Denton a meeting with,the NRC staff and consultants on December 16, 1980 for the purpose of providing a comprehensive program to,assess the significance of the discovery of the new faults including consideration of their impact
. on.-the seismic design adequacy of the facility.
They also plan to.solicit the assistance of NESCO and their consultants and will seek our review of tPeir proposed program.
I >>sill also plan to inform relevant DOE and waste isolation groups (NMSS) of the meeting.
WNP-2 will plan on submitting an annotated agenda about a week before the meeting.
We will work with them t'o develop this agenda in order to have the most productive meeting possible.
This approach >>sill allow for the best use of our available resources and allow WNP-2 to proceed with a more focussed'rogram of investigation following the meeting.
Dr. Justus will proceed with completion of hi.s trip report after the GETR meetings.
Based on. our present understanding and due to the, relatively early stage of the Gable Mountain fault investigations, we cannot reach any immediate conclusion >>sith respect to the safety significance that these faults may have on the HNP>>2.
V I will keep you informed of any new developments as the m'ecting date approaches.,
