EllCLOSURE WISC0llSIfl UTILITIES PROJECT HAVEN NUCLEAR PLAflT APPLICAtlTS' RESPONSE TO U. S. NUCLEAR REGULATORY COMMISS10ft REQUEST FOR ADDITIONAL INFORMATION Dated July 11, 1979
NRC QUESTION 361.13 Appendix 2P (NRC Letter dated July ll, 1979)
On page 23 of PSAR Appendix 2P the following statements are made:
"These terraces appear to be associated with channels on the bedrock surface.
Good evidence of the association of the terraces with a bedrock channel is observed on Lines 26 and 28 (Figure 100). On these lines a zone of channeling is observed on the bedrock as well as in glacial tills in the immediate vicinity of the terraces. These terraces appear as channel walls on Lines 26 and 28 where the bedrock erosion is more pronounced relative to the erosion on Lines 24, 20 and 32.
The bedrock channel trends north-south and extends to Line 44 in the north.
In the south it appears to extend to Line 14 with the exception that no channeling was observed on intermediate Lines 22 and 20 (Figure 6). The absence of channeling on Lines 22 and 20 suggests that the bedrock channel may have been eroded away in this area by glacial scouring."
PSAR, Appendix 2P, Figure 6 (Bedrock Features Map) does not reflect the bedrock channel as described above.
Specifically, the figure does not reflect the channels extend northward to Line 44 or the southern extension to Line 14.
Provide the necessary data and discussion to clarify this apparent discrepancy.
RESPONSE
The description of the bedrock channels on page 23 and 24 of Appendix 2P is based on a preliminary draft of the bedrock contours and the bedrock features maps. The final figures are provided in Appendix 2P, Figures 5 and 6.
In order to correct this discrepancy the following should be deleted on page 23:
The bedrock channel trends north-south and extends to Line 44 in the north.
In the south it appears to extend to Line 14 with the exception that no channeling was observcd on intermediate Lines 22 and 20 (Figure 6). The absence of channeling on Lines 22 and 20 suggests that the bedrock channel may have been eroded away in this area by glacial scouring. A tributary to this bedrock channel was located in the northwestern part of the survey area.
The following should be substituted for the deleted portion of page 23:
Several bedrock channels have been identified on the bedrock sreface.
They generally trend easterly but swing northerly in the eastern most portion of the survey area (Figure 6).
f4RC QUESTIOil 361.14 Appendices 2P and 20 (f1RC Letter dated, gly 11, 1979)
Provide full size copies of the following offshore Fairfield geophysical lines:
Area I - Lines 15,17 Area II - Lines 58, 60, 25, 27 RESP 0llSE Five full-size copies of the h mil and 1 mil data from geophysical lines 15 and 17, Area I, and lines 25, 27, 58 and 60, Area II, are being transmitted separately.
NRC QUESTION 361.15 Appendix 2R (.1RC Letter dated July 11,1979)
On page 8 of PSAR Appendix 2R, Weston Geophysical discusses two mapped escarpment like features that they felt could be interpreted as faults. The first feature occurs on Fairfield Lines 18, 26, and 28.
It is further discussed in the Fairfield Industries report included as PSAR Appendix 2P.
The second feature described by Weston as occurring on Fairfield geophysical lines 44, 15,17 and 21, is not discussed in the remainder of the PSAR.
Discuss in detail all data available concerning this feature, including fault parameters and relationship to the regional geology.
RESPONSE
Pages 3 and 4 of the Supplement to Engineering Geophysical Report Lake Michigan Area I (Appendix 2P) discuss these escarpments.
A discussion of these escarp-ments is also provided in Appendix 2M, F292 2M-15.
NRC OUESTION 361.16 Appendix 2Q (URC Letter dated July 11,1979)
Pages 21 thru 24 of PSAR Appendix 2Q discuss four magnetic anomalies, numbered 1, 2, 3 and 4.
The PSAR references Appendix 2Q, Figure 8 for the anomalies location in the Fairfield Study Area II.
The lucation and areal extent of anomalics 1, 2, 3 and 4 is unclear as shown on Figure 8, Appendix 2Q.
Please nodify Figure 8 to clarify the location and areal extent of these ancmalies.
RESPONSE
Figure 8, attached, has been reproduced to show the location and extent of the four magnetic anoralics discussed in Appendix 2Q.
