Operating License No. TR-1 Docket No. 50-70
Dear Administrative Judges:
l l
Since the last prehearing conference call between the parties to this pro-ceeding and the Board held on May 18, 1981, the parties have agreed and l-stipulated for the purposes of this Show Cause proceeding, that the follow-ing four additional matters are not in issue among the parties, can be l
accepted by the Board as given in its decision, and need not be litigated in the forthcoming hearings:
1.
The procedure used to access the stability of hillside deposits as a result of an earthquake as described in Section 2.3, page 3, is appropriate for the purpose of this proceeding.
2.
The investigations and reports provided by General Electric regarding landslides satisfy the requirements of 10 CFR Part 100, Appendix A, Section V Seismic and Geologic Design Bases ((d) Detennination of Other Design Conditions; l
(2) Slope Stability).
In addition these investigations and reports are in agreement with Standard Review Plan Section 2.5.5, Stability of Slopes.
3.
An earthquake-induced slope displacement (landslide) l of im is conservative.

4.
Ground surface displacements resulting from these
's slope movements would be ex>ected to occur near the toe of the slope, in the vicinity of t1e observed shear zone, and at some distance (approximately 300 feet) from the GETR plant.. There-fore, ground surface displacements due to the postulated landslide must be considered in the design of safety related equipment located near the toe of the slope (e.g., fuel. flood-ing system piping) but need not be considered in the design of the GETR reactor structure.
The four matters were included in the Staff's " Request For Admissions.
Interrogatories..and Request For Documents of Intervenors" dated March 16, 1981, at page 8, as admission request numbers E.1-4.
The statements were taken from the Staff's October 27, 1980 Safety Evaluation, Part I.
Pursuant to a canmunication with Chairman Grossman, I understand that the Board does not intend to question on the subject matter of the above issues.
Accordingly, the Staff does not now intend to bring Mr. Greeves to the hearing to testify on the subject of landslide characteristics. Staff witness Joseph Martore will be prepared to respond to questions regarding the impact of a landslide on the fuel flooding system piping near the toe of-the slope.
Sincerely,
