9.3 Ground Movement (sink holes or geo-sliding
==
Description:==
Ground movement caused by sink holes and/or dissolution of the limestone under the containment can result in lack of foundation support.
Data to be collected and Analyzed:
1.Geo-technical report-Gilbert Geotechnical Study Section 1.2.11 (1971) (FM 9.3 Exhibit 1)
- 2. FSAR Chapter 2 Section 2.5.7.2 (FM 9.3 Exhibit 2)
- 3. E-mail from Glen Pugh to Craig Miller (FM 9.3 Exhibit 3)
- 4. Buttress and Dome Survey Data (FM 9.3 Exhibit 4)
Verified Refuting Evidence:
- a.
The limestone supporting the containment was cement grouted to assure the continuity and integrity of the material. (FM 9.3 Exhibit 1)
- b.
There is no record of an observation of building cracking or sinkhole consistent with FSAR conclusions. (FM 9.3 Exhibits 2 and 3)
- c.
The Buttress and dome survey data show that the containment structure remains plum and the containment has not settled. (FM 9.3 Exhibit 4) See FM 1.5 for a more detailed discussion.
Verified Supporting Evidence:
None
==
Conclusion:==
There is no indication of containment settlement sufficient to cause added, asymmetrical I
